exams and tests
How to diagnose Adult Acute Lymphoblastic Leukemia ?
Tests that examine the blood and bone marrow are used to detect (find) and diagnose adult ALL. The following tests and procedures may be used: - Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as infection or anything else that seems unusual. A history of the patient's health habits and past illnesses and treatments will also be taken. - Complete blood count (CBC) with differential : A procedure in which a sample of blood is drawn and checked for the following: - The number of red blood cells and platelets. - The number and type of white blood cells. - The amount of hemoglobin (the protein that carries oxygen) in the red blood cells. - The portion of the blood sample made up of red blood cells. - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. - Peripheral blood smear : A procedure in which a sample of blood is checked for blast cells, the number and kinds of white blood cells, the number of platelets, and changes in the shape of blood cells. - Bone marrow aspiration and biopsy : The removal of bone marrow, blood, and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. A pathologist views the bone marrow, blood, and bone under a microscope to look for abnormal cells. The following tests may be done on the samples of blood or bone marrow tissue that are removed: - Cytogenetic analysis: A laboratory test in which the cells in a sample of blood or bone marrow are looked at under a microscope to find out if there are certain changes in the chromosomes of lymphocytes. For example, in Philadelphia chromosome positive ALL, part of one chromosome switches places with part of another chromosome. This is called the Philadelphia chromosome. - Immunophenotyping : A process used to identify cells, based on the types of antigens or markers on the surface of the cell. This process is used to diagnose the subtype of ALL by comparing the cancer cells to normal cells of the immune system. For example, a cytochemistry study may test the cells in a sample of tissue using chemicals (dyes) to look for certain changes in the sample. A chemical may cause a color change in one type of leukemia cell but not in another type of leukemia cell.

outlook
What is the outlook for Adult Acute Lymphoblastic Leukemia ?
Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on the following: - The age of the patient. - Whether the cancer has spread to the brain or spinal cord. - Whether there are certain changes in the genes, including the Philadelphia chromosome. - Whether the cancer has been treated before or has recurred (come back).

susceptibility
Who is at risk for Adult Acute Lymphoblastic Leukemia? ?
Previous chemotherapy and exposure to radiation may increase the risk of developing ALL. Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesnt mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Possible risk factors for ALL include the following: - Being male. - Being white. - Being older than 70. - Past treatment with chemotherapy or radiation therapy. - Being exposed to high levels of radiation in the environment (such as nuclear radiation). - Having certain genetic disorders, such as Down syndrome.

stages
What are the stages of Adult Acute Lymphoblastic Leukemia ?
Key Points - Once adult ALL has been diagnosed, tests are done to find out if the cancer has spread to the central nervous system (brain and spinal cord) or to other parts of the body. - There is no standard staging system for adult ALL. Once adult ALL has been diagnosed, tests are done to find out if the cancer has spread to the central nervous system (brain and spinal cord) or to other parts of the body. The extent or spread of cancer is usually described as stages. It is important to know whether the leukemia has spread outside the blood and bone marrow in order to plan treatment. The following tests and procedures may be used to determine if the leukemia has spread: - Chest x-ray : An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. - Lumbar puncture : A procedure used to collect a sample of cerebrospinal fluid (CSF) from the spinal column. This is done by placing a needle between two bones in the spine and into the CSF around the spinal cord and removing a sample of the fluid. The sample of CSF is checked under a microscope for signs that leukemia cells have spread to the brain and spinal cord. This procedure is also called an LP or spinal tap. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of the abdomen, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). There is no standard staging system for adult ALL. The disease is described as untreated, in remission, or recurrent. Untreated adult ALL The ALL is newly diagnosed and has not been treated except to relieve signs and symptoms such as fever, bleeding, or pain. - The complete blood count is abnormal. - More than 5% of the cells in the bone marrow are blasts (leukemia cells). - There are signs and symptoms of leukemia. Adult ALL in remission The ALL has been treated. - The complete blood count is normal. - 5% or fewer of the cells in the bone marrow are blasts (leukemia cells). - There are no signs or symptoms of leukemia other than in the bone marrow.

treatment
What are the treatments for Adult Acute Lymphoblastic Leukemia ?
Key Points - There are different types of treatment for patients with adult ALL. - The treatment of adult ALL usually has two phases. - Four types of standard treatment are used: - Chemotherapy - Radiation therapy - Chemotherapy with stem cell transplant - Targeted therapy - New types of treatment are being tested in clinical trials. - Biologic therapy - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Patients with ALL may have late effects after treatment. - Follow-up tests may be needed. There are different types of treatment for patients with adult ALL. Different types of treatment are available for patients with adult acute lymphoblastic leukemia (ALL). Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment. The treatment of adult ALL usually has two phases. The treatment of adult ALL is done in phases: - Remission induction therapy: This is the first phase of treatment. The goal is to kill the leukemia cells in the blood and bone marrow. This puts the leukemia into remission. - Post-remission therapy: This is the second phase of treatment. It begins once the leukemia is in remission. The goal of post-remission therapy is to kill any remaining leukemia cells that may not be active but could begin to regrow and cause a relapse. This phase is also called remission continuation therapy. Treatment called central nervous system (CNS) sanctuary therapy is usually given during each phase of therapy. Because standard doses of chemotherapy may not reach leukemia cells in the CNS (brain and spinal cord), the cells are able to "find sanctuary" (hide) in the CNS. Systemic chemotherapy given in high doses, intrathecal chemotherapy, and radiation therapy to the brain are able to reach leukemia cells in the CNS. They are given to kill the leukemia cells and lessen the chance the leukemia will recur (come back). CNS sanctuary therapy is also called CNS prophylaxis. Four types of standard treatment are used: Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid (intrathecal chemotherapy), an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). Combination chemotherapy is treatment using more than one anticancer drug. The way the chemotherapy is given depends on the type and stage of the cancer being treated. Intrathecal chemotherapy may be used to treat adult ALL that has spread, or may spread, to the brain and spinal cord. When used to lessen the chance leukemia cells will spread to the brain and spinal cord, it is called central nervous system (CNS) sanctuary therapy or CNS prophylaxis. See Drugs Approved for Acute Lymphoblastic Leukemia for more information. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type of cancer. External radiation therapy may be used to treat adult ALL that has spread, or may spread, to the brain and spinal cord. When used this way, it is called central nervous system (CNS) sanctuary therapy or CNS prophylaxis. External radiation therapy may also be used as palliative therapy to relieve symptoms and improve quality of life. Chemotherapy with stem cell transplant Stem cell transplant is a method of giving chemotherapy and replacing blood-forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body's blood cells. See Drugs Approved for Acute Lymphoblastic Leukemia for more information. Targeted therapy Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Targeted therapy drugs called tyrosine kinase inhibitors are used to treat some types of adult ALL. These drugs block the enzyme, tyrosine kinase, that causes stem cells to develop into more white blood cells (blasts) than the body needs. Three of the drugs used are imatinib mesylate (Gleevec), dasatinib, and nilotinib. See Drugs Approved for Acute Lymphoblastic Leukemia for more information. New types of treatment are being tested in clinical trials. This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website. Biologic therapy Biologic therapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Patients with ALL may have late effects after treatment. Side effects from cancer treatment that begin during or after treatment and continue for months or years are called late effects. Late effects of treatment for ALL may include the risk of second cancers (new types of cancer). Regular follow-up exams are very important for long-term survivors. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups. Treatment Options for Adult Acute Lymphoblastic Leukemia Untreated Adult Acute Lymphoblastic Leukemia Standard treatment of adult acute lymphoblastic leukemia (ALL) during the remission induction phase includes the following: - Combination chemotherapy. - Tyrosine kinase inhibitor therapy with imatinib mesylate, in certain patients. Some of these patients will also have combination chemotherapy. - Supportive care including antibiotics and red blood cell and platelet transfusions. - CNS prophylaxis therapy including chemotherapy (intrathecal and/or systemic) with or without radiation therapy to the brain. Check the list of NCI-supported cancer clinical trials that are now accepting patients with untreated adult acute lymphoblastic leukemia. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website. Adult Acute Lymphoblastic Leukemia in Remission Standard treatment of adult ALL during the post-remission phase includes the following: - Chemotherapy. - Tyrosine kinase inhibitor therapy. - Chemotherapy with stem cell transplant. - CNS prophylaxis therapy including chemotherapy (intrathecal and/or systemic) with or without radiation therapy to the brain. Check the list of NCI-supported cancer clinical trials that are now accepting patients with adult acute lymphoblastic leukemia in remission. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website. Recurrent Adult Acute Lymphoblastic Leukemia Standard treatment of recurrent adult ALL may include the following: - Combination chemotherapy followed by stem cell transplant. - Low-dose radiation therapy as palliative care to relieve symptoms and improve the quality of life. - Tyrosine kinase inhibitor therapy with dasatinib for certain patients. Some of the treatments being studied in clinical trials for recurrent adult ALL include the following: - A clinical trial of stem cell transplant using the patient's stem cells. - A clinical trial of biologic therapy. - A clinical trial of new anticancer drugs. Check the list of NCI-supported cancer clinical trials that are now accepting patients with recurrent adult acute lymphoblastic leukemia. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug.

What is (are) Skin Cancer ?
Key Points - Skin cancer is a disease in which malignant (cancer) cells form in the tissues of the skin. - There are several types of skin cancer. - Skin cancer is the most common cancer in the United States. Skin cancer is a disease in which malignant (cancer) cells form in the tissues of the skin. The skin is the bodys largest organ. It protects against heat, sunlight, injury, and infection. Skin also helps control body temperature and stores water, fat, and vitamin D. The skin has several layers, but the two main layers are the epidermis (upper or outer layer) and the dermis (lower or inner layer). The epidermis is made up of 3 kinds of cells: - Squamous cells are the thin, flat cells that make up most of the epidermis. - Basal cells are the round cells under the squamous cells. - Melanocytes are found throughout the lower part of the epidermis. They make melanin, the pigment that gives skin its natural color. When skin is exposed to the sun, melanocytes make more pigment, causing the skin to tan, or darken. The dermis contains blood and lymph vessels, hair follicles, and glands. See the following PDQ summaries for more information about skin cancer: - Skin Cancer Screening - Skin Cancer Treatment - Melanoma Treatment - Genetics of Skin Cancer There are several types of skin cancer. The most common types of skin cancer are squamous cell carcinoma, which forms in the squamous cells and basal cell carcinoma, which forms in the basal cells. Squamous cell carcinoma and basal cell carcinoma are also called nonmelanoma skin cancers. Melanoma, which forms in the melanocytes, is a less common type of skin cancer that grows and spreads quickly. Skin cancer can occur anywhere on the body, but it is most common in areas exposed to sunlight, such as the face, neck, hands, and arms. Skin cancer is the most common cancer in the United States. Basal cell carcinoma and squamous cell carcinoma are the most common types of skin cancer in the United States. The number of new cases of nonmelanoma skin cancer appears to be increasing every year. These nonmelanoma skin cancers can usually be cured. The number of new cases of melanoma has been increasing for at least 30 years. Melanoma is more likely to spread to nearby tissues and other parts of the body and can be harder to cure. Finding and treating melanoma skin cancer early may help prevent death from melanoma.

How to prevent Skin Cancer ?
Key Points - Avoiding risk factors and increasing protective factors may help prevent cancer. - Being exposed to ultraviolet radiation is a risk factor for skin cancer. - It is not known if the following lower the risk of nonmelanoma skin cancer: - Sunscreen use and avoiding sun exposure - Chemopreventive agents - It is not known if the following lower the risk of melanoma: - Sunscreen - Counseling and protecting the skin from the sun - Cancer prevention clinical trials are used to study ways to prevent cancer. - New ways to prevent skin cancer are being studied in clinical trials. Avoiding risk factors and increasing protective factors may help prevent cancer. Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer. Being exposed to ultraviolet radiation is a risk factor for skin cancer. Some studies suggest that being exposed to ultraviolet (UV) radiation and the sensitivity of a persons skin to UV radiation are risk factors for skin cancer. UV radiation is the name for the invisible rays that are part of the energy that comes from the sun. Sunlamps and tanning beds also give off UV radiation. Risk factors for nonmelanoma and melanoma cancers are not the same. - Risk factors for nonmelanoma skin cancer: - Being exposed to natural sunlight or artificial sunlight (such as from tanning beds) over long periods of time. - Having a fair complexion, which includes the following: - Fair skin that freckles and burns easily, does not tan, or tans poorly. - Blue or green or other light-colored eyes. - Red or blond hair. - Having actinic keratosis. - Past treatment with radiation. - Having a weakened immune system. - Being exposed to arsenic. - Risk factors for melanoma skin cancer: - Having a fair complexion, which includes the following: - Fair skin that freckles and burns easily, does not tan, or tans poorly. - Blue or green or other light-colored eyes. - Red or blond hair. - Being exposed to natural sunlight or artificial sunlight (such as from tanning beds) over long periods of time. - Having a history of many blistering sunburns, especially as a child or teenager. - Having several large or many small moles. - Having a family history of unusual moles (atypical nevus syndrome). - Having a family or personal history of melanoma. - Being white. It is not known if the following lower the risk of nonmelanoma skin cancer: Sunscreen use and avoiding sun exposure It is not known if nonmelanoma skin cancer risk is decreased by staying out of the sun, using sunscreens, or wearing protective clothing when outdoors. This is because not enough studies have been done to prove this. Sunscreen may help decrease the amount of UV radiation to the skin. One study found that wearing sunscreen can help prevent actinic keratoses, scaly patches of skin that sometimes become squamous cell carcinoma. The harms of using sunscreen are likely to be small and include allergic reactions to skin creams and lower levels of vitamin D made in the skin because of less sun exposure. It is also possible that when a person uses sunscreen to avoid sunburn they may spend too much time in the sun and be exposed to harmful UV radiation. Although protecting the skin and eyes from the sun has not been proven to lower the chance of getting skin cancer, skin experts suggest the following: - Use sunscreen that protects against UV radiation. - Do not stay out in the sun for long periods of time, especially when the sun is at its strongest. - Wear long sleeve shirts, long pants, sun hats, and sunglasses, when outdoors. Chemopreventive agents Chemoprevention is the use of drugs, vitamins, or other agents to try to reduce the risk of cancer. The following chemopreventive agents have been studied to find whether they lower the risk of nonmelanoma skin cancer: Beta carotene Studies of beta carotene (taken as a supplement in pills) have not shown that it prevents nonmelanoma skin cancer from forming or coming back. Isotretinoin High doses of isotretinoin have been shown to prevent new skin cancers in patients with xeroderma pigmentosum. However, isotretinoin has not been shown to prevent nonmelanoma skin cancers from coming back in patients previously treated for nonmelanoma skin cancers. Treatment with isotretinoin can cause serious side effects. Selenium Studies have shown that selenium (taken in brewer's yeast tablets) does not lower the risk of basal cell carcinoma, and may increase the risk of squamous cell carcinoma. Celecoxib A study of celecoxib in patients with actinic keratosis and a history of nonmelanoma skin cancer found those who took celecoxib had slightly lower rates of recurrent nonmelanoma skin cancers. Celecoxib may have serious side effects on the heart and blood vessels. Alpha-difluoromethylornithine (DFMO) A study of alpha-difluoromethylornithine (DFMO) in patients with a history of nonmelanoma skin cancer showed that those who took DFMO had lower rates of nonmelanoma skin cancers coming back than those who took a placebo. DFMO may cause hearing loss which is usually temporary. Nicotinamide (vitamin B3) Studies have shown that nicotinamide (vitamin B3) helps prevent new actinic keratoses lesions from forming in people who had four or fewer actinic lesions before taking nicotinamide. More studies are needed to find out if nicotinamide prevents nonmelanoma skin cancer from forming or coming back. It is not known if the following lower the risk of melanoma: Sunscreen It has not been proven that using sunscreen to prevent sunburn can protect against melanoma caused by UV radiation. Other risk factors such as having skin that burns easily, having a large number of benign moles, or having atypical nevi may also play a role in whether melanoma forms. Counseling and protecting the skin from the sun It is not known if people who receive counseling or information about avoiding sun exposure make changes in their behavior to protect their skin from the sun. Cancer prevention clinical trials are used to study ways to prevent cancer. Cancer prevention clinical trials are used to study ways to lower the risk of developing certain types of cancer. Some cancer prevention trials are conducted with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are conducted with people who have had cancer and are trying to prevent another cancer of the same type or to lower their chance of developing a new type of cancer. Other trials are done with healthy volunteers who are not known to have any risk factors for cancer. The purpose of some cancer prevention clinical trials is to find out whether actions people take can prevent cancer. These may include eating fruits and vegetables, exercising, quitting smoking, or taking certain medicines, vitamins, minerals, or food supplements. New ways to prevent skin cancer are being studied in clinical trials. Clinical trials are taking place in many parts of the country. Information about clinical trials can be found in the Clinical Trials section of the NCI Web site. Check NCI's list of cancer clinical trials for nonmelanoma skin cancer prevention trials and melanoma prevention trials that are now accepting patients.

Key Points - Small intestine cancer is a rare disease in which malignant (cancer) cells form in the tissues of the small intestine. - There are five types of small intestine cancer. - Diet and health history can affect the risk of developing small intestine cancer. - Signs and symptoms of small intestine cancer include unexplained weight loss and abdominal pain. - Tests that examine the small intestine are used to detect (find), diagnose, and stage small intestine cancer. - Certain factors affect prognosis (chance of recovery) and treatment options. Small intestine cancer is a rare disease in which malignant (cancer) cells form in the tissues of the small intestine. The small intestine is part of the bodys digestive system, which also includes the esophagus, stomach, and large intestine. The digestive system removes and processes nutrients (vitamins, minerals, carbohydrates, fats, proteins, and water) from foods and helps pass waste material out of the body. The small intestine is a long tube that connects the stomach to the large intestine. It folds many times to fit inside the abdomen. There are five types of small intestine cancer. The types of cancer found in the small intestine are adenocarcinoma, sarcoma, carcinoid tumors, gastrointestinal stromal tumor, and lymphoma. This summary discusses adenocarcinoma and leiomyosarcoma (a type of sarcoma). Adenocarcinoma starts in glandular cells in the lining of the small intestine and is the most common type of small intestine cancer. Most of these tumors occur in the part of the small intestine near the stomach. They may grow and block the intestine. Leiomyosarcoma starts in the smooth muscle cells of the small intestine. Most of these tumors occur in the part of the small intestine near the large intestine. See the following PDQ summaries for more information on small intestine cancer: - Adult Soft Tissue Sarcoma Treatment - Childhood Soft Tissue Sarcoma Treatment - Adult Non-Hodgkin Lymphoma Treatment - Childhood Non-Hodgkin Lymphoma Treatment - Gastrointestinal Carcinoid Tumors Treatment - Gastrointestinal Stromal Tumors Treatment

Who is at risk for Small Intestine Cancer? ?
Diet and health history can affect the risk of developing small intestine cancer. Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Risk factors for small intestine cancer include the following: - Eating a high-fat diet. - Having Crohn disease. - Having celiac disease. - Having familial adenomatous polyposis (FAP).

How to diagnose Small Intestine Cancer ?
Tests that examine the small intestine are used to detect (find), diagnose, and stage small intestine cancer.Procedures that make pictures of the small intestine and the area around it help diagnose small intestine cancer and show how far the cancer has spread. The process used to find out if cancer cells have spread within and around the small intestine is called staging. In order to plan treatment, it is important to know the type of small intestine cancer and whether the tumor can be removed by surgery. Tests and procedures to detect, diagnose, and stage small intestine cancer are usually done at the same time. The following tests and procedures may be used: - Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken. - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. - Liver function tests : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by the liver. A higher than normal amount of a substance can be a sign of liver disease that may be caused by small intestine cancer. - Endoscopy : A procedure to look at organs and tissues inside the body to check for abnormal areas. There are different types of endoscopy: - Upper endoscopy : A procedure to look at the inside of the esophagus, stomach, and duodenum (first part of the small intestine, near the stomach). An endoscope is inserted through the mouth and into the esophagus, stomach, and duodenum. An endoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer. - Capsule endoscopy : A procedure to look at the inside of the small intestine. A capsule that is about the size of a large pill and contains a light and a tiny wireless camera is swallowed by the patient. The capsule travels through the digestive tract, including the small intestine, and sends many pictures of the inside of the digestive tract to a recorder that is worn around the waist or over the shoulder. The pictures are sent from the recorder to a computer and viewed by the doctor who checks for signs of cancer. The capsule passes out of the body during a bowel movement. - Double balloon endoscopy : A procedure to look at the inside of the small intestine. A special instrument made up of two tubes (one inside the other) is inserted through the mouth or rectum and into the small intestine. The inside tube (an endoscope with a light and lens for viewing) is moved through part of the small intestine and a balloon at the end of it is inflated to keep the endoscope in place. Next, the outer tube is moved through the small intestine to reach the end of the endoscope, and a balloon at the end of the outer tube is inflated to keep it in place. Then, the balloon at the end of the endoscope is deflated and the endoscope is moved through the next part of the small intestine. These steps are repeated many times as the tubes move through the small intestine. The doctor is able to see the inside of the small intestine through the endoscope and use a tool to remove samples of abnormal tissue. The tissue samples are checked under a microscope for signs of cancer. This procedure may be done if the results of a capsule endoscopy are abnormal. This procedure is also called double balloon enteroscopy. - Laparotomy : A surgical procedure in which an incision (cut) is made in the wall of the abdomen to check the inside of the abdomen for signs of disease. The size of the incision depends on the reason the laparotomy is being done. Sometimes organs or lymph nodes are removed or tissue samples are taken and checked under a microscope for signs of disease. - Biopsy : The removal of cells or tissues so they can be viewed under a microscope to check for signs of cancer. This may be done during an endoscopy or laparotomy. The sample is checked by a pathologist to see if it contains cancer cells. - Upper GI series with small bowel follow-through: A series of x-rays of the esophagus, stomach, and small bowel. The patient drinks a liquid that contains barium (a silver-white metallic compound). The liquid coats the esophagus, stomach, and small bowel. X-rays are taken at different times as the barium travels through the upper GI tract and small bowel. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).

What is the outlook for Small Intestine Cancer ?
Certain factors affect prognosis (chance of recovery) and treatment options.The prognosis (chance of recovery) and treatment options depend on the following: - The type of small intestine cancer. - Whether the cancer is in the inner lining of the small intestine only or has spread into or beyond the wall of the small intestine. - Whether the cancer has spread to other places in the body, such as the lymph nodes, liver, or peritoneum (tissue that lines the wall of the abdomen and covers most of the organs in the abdomen). - Whether the cancer can be completely removed by surgery. - Whether the cancer is newly diagnosed or has recurred.

stages
What are the stages of Small Intestine Cancer ?
Key Points - Tests and procedures to stage small intestine cancer are usually done at the same time as diagnosis. - There are three ways that cancer spreads in the body. - Cancer may spread from where it began to other parts of the body. - Small intestine cancer is grouped according to whether or not the tumor can be completely removed by surgery. Tests and procedures to stage small intestine cancer are usually done at the same time as diagnosis. Staging is used to find out how far the cancer has spread, but treatment decisions are not based on stage. See the General Information section for a description of tests and procedures used to detect, diagnose, and stage small intestine cancer. There are three ways that cancer spreads in the body. Cancer can spread through tissue, the lymph system, and the blood: - Tissue. The cancer spreads from where it began by growing into nearby areas. - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body. - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body. Cancer may spread from where it began to other parts of the body. When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood. - Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body. - Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body. The metastatic tumor is the same type of cancer as the primary tumor. For example, if small intestine cancer spreads to the liver, the cancer cells in the liver are actually small intestine cancer cells. The disease is metastatic small intestine cancer, not liver cancer. Small intestine cancer is grouped according to whether or not the tumor can be completely removed by surgery. Treatment depends on whether the tumor can be removed by surgery and if the cancer is being treated as a primary tumor or is metastatic cancer.

treatment
What are the treatments for Small Intestine Cancer ?
Key Points - There are different types of treatment for patients with small intestine cancer. - Three types of standard treatment are used: - Surgery - Radiation therapy - Chemotherapy - New types of treatment are being tested in clinical trials. - Biologic therapy - Radiation therapy with radiosensitizers - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for patients with small intestine cancer. Different types of treatments are available for patients with small intestine cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment. Three types of standard treatment are used: Surgery Surgery is the most common treatment of small intestine cancer. One of the following types of surgery may be done: - Resection: Surgery to remove part or all of an organ that contains cancer. The resection may include the small intestine and nearby organs (if the cancer has spread). The doctor may remove the section of the small intestine that contains cancer and perform an anastomosis (joining the cut ends of the intestine together). The doctor will usually remove lymph nodes near the small intestine and examine them under a microscope to see whether they contain cancer. - Bypass: Surgery to allow food in the small intestine to go around (bypass) a tumor that is blocking the intestine but cannot be removed. Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type of the cancer being treated. External radiation therapy is used to treat small intestine cancer. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated. New types of treatment are being tested in clinical trials. This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website. Biologic therapy Biologic therapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy. Radiation therapy with radiosensitizers Radiosensitizers are drugs that make tumor cells more sensitive to radiation therapy. Combining radiation therapy with radiosensitizers may kill more tumor cells. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups. Treatment Options for Small Intestine Cancer Small Intestine Adenocarcinoma When possible, treatment of small intestine adenocarcinoma will be surgery to remove the tumor and some of the normal tissue around it. Treatment of small intestine adenocarcinoma that cannot be removed by surgery may include the following: - Surgery to bypass the tumor. - Radiation therapy as palliative therapy to relieve symptoms and improve the patient's quality of life. - A clinical trial of radiation therapy with radiosensitizers, with or without chemotherapy. - A clinical trial of new anticancer drugs. - A clinical trial of biologic therapy. Check the list of NCI-supported cancer clinical trials that are now accepting patients with small intestine adenocarcinoma. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website. Small Intestine Leiomyosarcoma When possible, treatment of small intestine leiomyosarcoma will be surgery to remove the tumor and some of the normal tissue around it. Treatment of small intestine leiomyosarcoma that cannot be removed by surgery may include the following: - Surgery (to bypass the tumor) and radiation therapy. - Surgery, radiation therapy, or chemotherapy as palliative therapy to relieve symptoms and improve the patient's quality of life. - A clinical trial of new anticancer drugs. - A clinical trial of biologic therapy. Check the list of NCI-supported cancer clinical trials that are now accepting patients with small intestine leiomyosarcoma. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website. Recurrent Small Intestine Cancer Treatment of recurrent small intestine cancer that has spread to other parts of the body is usually a clinical trial of new anticancer drugs or biologic therapy. Treatment of locally recurrent small intestine cancer may include the following: - Surgery. - Radiation therapy or chemotherapy as palliative therapy to relieve symptoms and improve the patient's quality of life. - A clinical trial of radiation therapy with radiosensitizers, with or without chemotherapy. Check the list of NCI-supported cancer clinical trials that are now accepting patients with recurrent small intestine cancer. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug.

What is (are) Childhood Astrocytomas ?
Key Points - Childhood astrocytoma is a disease in which benign (noncancer) or malignant (cancer) cells form in the tissues of the brain. - Astrocytomas may be benign (not cancer) or malignant (cancer). - The central nervous system controls many important body functions. - The cause of most childhood brain tumors is not known. - The signs and symptoms of astrocytomas are not the same in every child. - Tests that examine the brain and spinal cord are used to detect (find) childhood astrocytomas. - Childhood astrocytomas are usually diagnosed and removed in surgery. - Certain factors affect prognosis (chance of recovery) and treatment options. Childhood astrocytoma is a disease in which benign (noncancer) or malignant (cancer) cells form in the tissues of the brain. Astrocytomas are tumors that start in star-shaped brain cells called astrocytes. An astrocyte is a type of glial cell. Glial cells hold nerve cells in place, bring food and oxygen to them, and help protect them from disease, such as infection. Gliomas are tumors that form from glial cells. An astrocytoma is a type of glioma. Astrocytoma is the most common type of glioma diagnosed in children. It can form anywhere in the central nervous system (brain and spinal cord). This summary is about the treatment of tumors that begin in astrocytes in the brain (primary brain tumors). Metastatic brain tumors are formed by cancer cells that begin in other parts of the body and spread to the brain. Treatment of metastatic brain tumors is not discussed here. Brain tumors can occur in both children and adults. However, treatment for children may be different than treatment for adults. See the following PDQ summaries for more information about other types of brain tumors in children and adults: - Childhood Brain and Spinal Cord Tumors Treatment Overview - Adult Central Nervous System Tumors Treatment Astrocytomas may be benign (not cancer) or malignant (cancer). Benign brain tumors grow and press on nearby areas of the brain. They rarely spread into other tissues. Malignant brain tumors are likely to grow quickly and spread into other brain tissue. When a tumor grows into or presses on an area of the brain, it may stop that part of the brain from working the way it should. Both benign and malignant brain tumors can cause signs and symptoms and almost all need treatment. The central nervous system controls many important body functions. Astrocytomas are most common in these parts of the central nervous system (CNS): - Cerebrum : The largest part of the brain, at the top of the head. The cerebrum controls thinking, learning, problem-solving, speech, emotions, reading, writing, and voluntary movement. - Cerebellum : The lower, back part of the brain (near the middle of the back of the head). The cerebellum controls movement, balance, and posture. - Brain stem : The part that connects the brain to the spinal cord, in the lowest part of the brain (just above the back of the neck). The brain stem controls breathing, heart rate, and the nerves and muscles used in seeing, hearing, walking, talking, and eating. - Hypothalamus : The area in the middle of the base of the brain. It controls body temperature, hunger, and thirst. - Visual pathway: The group of nerves that connect the eye with the brain. - Spinal cord: The column of nerve tissue that runs from the brain stem down the center of the back. It is covered by three thin layers of tissue called membranes. The spinal cord and membranes are surrounded by the vertebrae (back bones). Spinal cord nerves carry messages between the brain and the rest of the body, such as a message from the brain to cause muscles to move or a message from the skin to the brain to feel touch.

Who is at risk for Childhood Astrocytomas? ?
Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesnt mean that you will not get cancer. Talk with your child's doctor if you think your child may be at risk. Possible risk factors for astrocytoma include: - Past radiation therapy to the brain. - Having certain genetic disorders, such as neurofibromatosis type 1 (NF1) or tuberous sclerosis.

symptoms
What are the symptoms of Childhood Astrocytomas ?
The signs and symptoms of astrocytomas are not the same in every child. Signs and symptoms depend on the following: - Where the tumor forms in the brain or spinal cord. - The size of the tumor. - How fast the tumor grows. - The child's age and development. Some tumors do not cause signs or symptoms. Signs and symptoms may be caused by childhood astrocytomas or by other conditions. Check with your child's doctor if your child has any of the following: - Morning headache or headache that goes away after vomiting. - Nausea and vomiting. - Vision, hearing, and speech problems. - Loss of balance and trouble walking. - Worsening handwriting or slow speech. - Weakness or change in feeling on one side of the body. - Unusual sleepiness. - More or less energy than usual. - Change in personality or behavior. - Seizures. - Weight loss or weight gain for no known reason. - Increase in the size of the head (in infants).

exams and tests
How to diagnose Childhood Astrocytomas ?
Tests that examine the brain and spinal cord are used to detect (find) childhood astrocytomas. The following tests and procedures may be used: - Physical exam and history : An exam of the body to check general signs of health. This includes checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken. - Neurological exam : A series of questions and tests to check the brain, spinal cord, and nerve function. The exam checks a persons mental status, coordination, and ability to walk normally, and how well the muscles, senses, and reflexes work. This may also be called a neuro exam or a neurologic exam. - Visual field exam: An exam to check a persons field of vision (the total area in which objects can be seen). This test measures both central vision (how much a person can see when looking straight ahead) and peripheral vision (how much a person can see in all other directions while staring straight ahead). The eyes are tested one at a time. The eye not being tested is covered. - MRI (magnetic resonance imaging) with gadolinium : A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of the brain and spinal cord. A substance called gadolinium is injected into a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI). Sometimes magnetic resonance spectroscopy (MRS) is done during the same MRI scan to look at the chemical makeup of the brain tissue. Childhood astrocytomas are usually diagnosed and removed in surgery. If doctors think there may be an astrocytoma, a biopsy may be done to remove a sample of tissue. For tumors in the brain, a part of the skull is removed and a needle is used to remove tissue. Sometimes, the needle is guided by a computer. A pathologist views the tissue under a microscope to look for cancer cells. If cancer cells are found, the doctor may remove as much tumor as safely possible during the same surgery. Because it can be hard to tell the difference between types of brain tumors, you may want to have your child's tissue sample checked by a pathologist who has experience in diagnosing brain tumors. The following test may be done on the tissue that was removed: - Immunohistochemistry : A test that uses antibodies to check for certain antigens in a sample of tissue. The antibody is usually linked to a radioactive substance or a dye that causes the tissue to light up under a microscope. This type of test may be used to tell the difference between different types of cancer. An MIB-1 test is a type of immunohistochemistry that checks tumor tissue for an antigen called MIB-1. This may show how fast a tumor is growing. Sometimes tumors form in a place that makes them hard to remove. If removing the tumor may cause severe physical, emotional, or learning problems, a biopsy is done and more treatment is given after the biopsy. Children who have NF1 may form a low-grade astrocytoma in the area of the brain that controls vision and may not need a biopsy. If the tumor does not continue to grow or symptoms do not occur, surgery to remove the tumor may not be needed.

outlook
What is the outlook for Childhood Astrocytomas ?
Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on the following: - Whether the tumor is a low-grade or high-grade astrocytoma. - Where the tumor has formed in the CNS and if it has spread to nearby tissue or to other parts of the body. - How fast the tumor is growing. - The child's age. - Whether cancer cells remain after surgery. - Whether there are changes in certain genes. - Whether the child has NF1 or tuberous sclerosis. - Whether the child has diencephalic syndrome (a condition which slows physical growth). - Whether the child has intracranial hypertension (cerebrospinal fluid pressure within the skull is high) at the time of diagnosis. - Whether the astrocytoma has just been diagnosed or has recurred (come back). For recurrent astrocytoma, prognosis and treatment depend on how much time passed between the time treatment ended and the time the astrocytoma recurred.

stages
What are the stages of Childhood Astrocytomas ?
Key Points - The grade of the tumor is used to plan cancer treatment. - Low-grade astrocytomas - High-grade astrocytomas - An MRI is done after surgery. The grade of the tumor is used to plan cancer treatment. Staging is the process used to find out how much cancer there is and if cancer has spread. It is important to know the stage in order to plan treatment. There is no standard staging system for childhood astrocytoma. Treatment is based on the following: - Whether the tumor is low grade or high grade. - Whether the tumor is newly diagnosed or recurrent (has come back after treatment). The grade of the tumor describes how abnormal the cancer cells look under a microscope and how quickly the tumor is likely to grow and spread. The following grades are used: Low-grade astrocytomas Low-grade astrocytomas are slow-growing and rarely spread to other parts of the brain and spinal cord or other parts of the body. There are many types of low-grade astrocytomas. Low-grade astrocytomas can be either: - Grade I tumors pilocytic astrocytoma, subependymal giant cell tumor, or angiocentric glioma. - Grade II tumors diffuse astrocytoma, pleomorphic xanthoastrocytoma, or choroid glioma of the third ventricle. Children who have neurofibromatosis type 1 may have more than one low-grade tumor in the brain. Children who have tuberous sclerosis have an increased risk of subependymal giant cell astrocytoma. High-grade astrocytomas High-grade astrocytomas are fast-growing and often spread within the brain and spinal cord. There are several types of high-grade astrocytomas. High grade astrocytomas can be either: - Grade III tumors anaplastic astrocytoma or anaplastic pleomorphic xanthoastrocytoma. - Grade IV tumors glioblastoma or diffuse midline glioma. Childhood astrocytomas usually do not spread to other parts of the body. An MRI is done after surgery. An MRI (magnetic resonance imaging) is done in the first few days after surgery. This is to find out how much tumor, if any, remains after surgery and to plan further treatment.

what research (or clinical trials) is being done for Childhood Astrocytomas ?
New types of treatment are being tested in clinical trials. This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website. Other drug therapy Lenalidomide is a type of angiogenesis inhibitor. It prevents the growth of new blood vessels that are needed by a tumor to grow. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.

When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Because cancer in children is rare, taking part in a clinical trial should be considered. Some clinical trials are open only to patients who have not started treatment. Children with astrocytomas should have their treatment planned by a team of health care providers who are experts in treating childhood brain tumors. Treatment will be overseen by a pediatric oncologist, a doctor who specializes in treating children with cancer. The pediatric oncologist works with other healthcare providers who are experts in treating children with brain tumors and who specialize in certain areas of medicine. These may include the following specialists: - Pediatrician. - Pediatric neurosurgeon. - Neurologist. - Neuropathologist. - Neuroradiologist. - Rehabilitation specialist. - Radiation oncologist. - Endocrinologist. - Psychologist. Childhood brain tumors may cause signs or symptoms that begin before the cancer is diagnosed and continue for months or years. Signs or symptoms caused by the tumor may begin before diagnosis. These signs or symptoms may continue for months or years. It is important to talk with your child's doctors about signs or symptoms caused by the tumor that may continue after treatment. Some cancer treatments cause side effects months or years after treatment has ended. Side effects from cancer treatment that begin during or after treatment and continue for months or years are called late effects. Late effects of cancer treatment may include the following: - Physical problems. - Changes in mood, feelings, thinking, learning, or memory. - Second cancers (new types of cancer). Some late effects may be treated or controlled. It is important to talk with your child's doctors about the effects cancer treatment can have on your child. (See the PDQ summary on Late Effects of Treatment for Childhood Cancer for more information.) Six types of treatment are used: Surgery Surgery is used to diagnose and treat childhood astrocytoma, as discussed in the General Information section of this summary. If cancer cells remain after surgery, further treatment depends on: - Where the remaining cancer cells are. - The grade of the tumor. - The age of the child. Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that remain. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy. Observation Observation is closely monitoring a patients condition without giving any treatment until signs or symptoms appear or change. Observation may be used: - If the patient has no symptoms, such as patients with neurofibromatosis type1. - If the tumor is small and is found when a different health problem is being diagnosed or treated. - After the tumor is removed by surgery until signs or symptoms appear or change. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. Certain ways of giving radiation therapy can help keep radiation from damaging nearby healthy tissue. These types of radiation therapy include the following: - Conformal radiation therapy: Conformal radiation therapy is a type of external radiation therapy that uses a computer to make a 3-dimensional (3-D) picture of the tumor and shapes the radiation beams to fit the tumor. - Intensity-modulated radiation therapy (IMRT): IMRT is a type of 3-dimensional (3-D) external radiation therapy that uses a computer to make pictures of the size and shape of the tumor. Thin beams of radiation of different intensities (strengths) are aimed at the tumor from many angles. - Stereotactic radiation therapy: Stereotactic radiation therapy is a type of external radiation therapy. A rigid head frame is attached to the skull to keep the head still during the radiation treatment. A machine aims radiation directly at the tumor. The total dose of radiation is divided into several smaller doses given over several days. This procedure is also called stereotactic external-beam radiation therapy and stereotaxic radiation therapy. - Proton beam radiation therapy: Proton-beam therapy is a type of high-energy, external radiation therapy. A radiation therapy machine aims streams of protons (tiny, invisible, positively-charged particles) at the cancer cells to kill them. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type of tumor and where the tumor formed in the brain or spinal cord. External radiation therapy is used to treat childhood astrocytomas. Radiation therapy to the brain can affect growth and development, especially in young children. For children younger than 3 years, chemotherapy may be given instead, to delay or reduce the need for radiation therapy. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). Combination chemotherapy is the use of more than one anticancer drug. The way the chemotherapy is given depends on the type of tumor and where the tumor formed in the brain or spinal cord. Systemic combination chemotherapy is used in the treatment of children with astrocytoma. High-dose chemotherapy may be used in the treatment of children with newly diagnosed high-grade astrocytoma. High-dose chemotherapy with stem cell transplant High-dose chemotherapy with stem cell transplant is a way of giving high doses of chemotherapy and replacing blood -forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body's blood cells. For high-grade astrocytoma that has come back after treatment, high-dose chemotherapy with stem cell transplant is used if there is only a small amount of tumor. Targeted therapy Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. There are different types of targeted therapy: - Monoclonal antibody therapy uses antibodies made in the laboratory, from a single type of immune system cell, to stop cancer cells. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion into a vein. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. There are different types of monoclonal antibody therapy: - Vascular endothelial growth factor (VEGF) inhibitor therapy: Cancer cells make a substance called VEGF, which causes new blood vessels to form (angiogenesis) and helps the cancer grow. VEGF inhibitors block VEGF and stop new blood vessels from forming. This may kill cancer cells because they need new blood vessels to grow. Bevacizumab is a VEGF inhibitor and angiogenesis inhibitor being used to treat childhood astrocytoma. - Immune checkpoint inhibitor therapy: PD-1 is a protein on the surface of T cells that helps keep the bodys immune responses in check. When PD-1 attaches to another protein called PDL-1 on a cancer cell, it stops the T cell from killing the cancer cell. PD-1 inhibitors attach to PDL-1 and allow the T cells to kill cancer cells. PD-1 inhibitors are being studied to treat high-grade astrocytoma that has recurred. - Protein kinase inhibitors work in different ways. There are several kinds of protein kinase inhibitors. - mTOR inhibitors stop cells from dividing and may prevent the growth of new blood vessels that tumors need to grow. Everolimus and sirolimus are mTOR inhibitors used to treat childhood subependymal giant cell astrocytomas. mTOR inhibitors also are being studied to treat low-grade astrocytoma that has recurred. - BRAF inhibitors block proteins needed for cell growth and may kill cancer cells. The BRAF inhibitor dabrafenib is being studied to treat low-grade astrocytoma that has recurred. Vemurafenib and dabrafenib have been used to treat high-grade astrocytomas that have recurred but more study is needed to know how well they work in children. - MEK inhibitors block proteins needed for cell growth and may kill cancer cells. MEK inhibitors such as selumetinib are being studied to treat low-grade astrocytoma that has recurred. See Drugs Approved for Brain Tumors for more information. New types of treatment are being tested in clinical trials. This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website. Other drug therapy Lenalidomide is a type of angiogenesis inhibitor. It prevents the growth of new blood vessels that are needed by a tumor to grow. If fluid builds up around the brain and spinal cord, a cerebrospinal fluid diversion procedure may be done. Cerebrospinal fluid diversion is a method used to drain fluid that has built up around the brain and spinal cord. A shunt (long, thin tube) is placed in a ventricle (fluid-filled space) of the brain and threaded under the skin to another part of the body, usually the abdomen. The shunt carries extra fluid away from the brain so it may be absorbed elsewhere in the body. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. (See the General Information section for a list of tests.) Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Regular MRIs will continue to be done after treatment has ended. The results of the MRI can show if your child's condition has changed or if the astrocytoma has recurred (come back). If the results of the MRI show a mass in the brain, a biopsy may be done to find out if it is made up of dead tumor cells or if new cancer cells are growing. Treatment Options for Childhood Astrocytomas Newly Diagnosed Childhood Low-Grade Astrocytomas When the tumor is first diagnosed, treatment for childhood low-grade astrocytoma depends on where the tumor is, and is usually surgery. An MRI is done after surgery to see if there is tumor remaining. If the tumor was completely removed by surgery, more treatment may not be needed and the child is closely watched to see if signs or symptoms appear or change. This is called observation. If there is tumor remaining after surgery, treatment may include the following: - Observation. - A second surgery to remove the tumor. - Radiation therapy, which may include conformal radiation therapy, intensity-modulated radiation therapy, proton beam radiation therapy, or stereotactic radiation therapy, when the tumor begins to grow again. - Combination chemotherapy with or without radiation therapy. In some cases, observation is used for children who have a visual pathway glioma. In other cases, treatment may include surgery to remove the tumor, radiation therapy, or chemotherapy. A goal of treatment is to save as much vision as possible. The effect of tumor growth on the child's vision will be closely followed during treatment. Children with neurofibromatosis type 1 (NF1) may not need treatment unless the tumor grows or signs or symptoms, such as vision problems, appear. When the tumor grows or signs or symptoms appear, treatment may include surgery to remove the tumor, radiation therapy, and/or chemotherapy. Children with tuberous sclerosis may develop benign (not cancer) tumors in the brain called subependymal giant cell astrocytomas (SEGAs). Targeted therapy with everolimus or sirolimus may be used instead of surgery, to shrink the tumors. Check the list of NCI-supported cancer clinical trials that are now accepting patients with childhood low-grade untreated astrocytoma or other tumor of glial origin. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your child's doctor about clinical trials that may be right for your child. General information about clinical trials is available from the NCI website. Recurrent Childhood Low-Grade Astrocytomas When low-grade astrocytoma recurs after treatment, it usually comes back where the tumor first formed. Before more cancer treatment is given, imaging tests, biopsy, or surgery are done to find out if there is cancer and how much there is. Treatment of recurrent childhood low-grade astrocytoma may include the following: - A second surgery to remove the tumor, if surgery was the only treatment given when the tumor was first diagnosed. - Radiation therapy to the tumor only, if radiation therapy was not used when the tumor was first diagnosed. Conformal radiation therapy may be given. - Chemotherapy, if the tumor recurred where it cannot be removed by surgery or the patient had radiation therapy when the tumor was first diagnosed. - Targeted therapy with a monoclonal antibody (bevacizumab) with or without chemotherapy. - A clinical trial of targeted therapy with a BRAF inhibitor (dabrafenib), an mTOR inhibitor (everolimus), or a MEK inhibitor (selumetinib). - A clinical trial of lenalidomide. Check the list of NCI-supported cancer clinical trials that are now accepting patients with recurrent childhood astrocytoma or other tumor of glial origin.

Talk with your child's doctor about clinical trials that may be right for your child. General information about clinical trials is available from the NCI website. Newly Diagnosed Childhood High-Grade Astrocytomas Treatment of childhood high-grade astrocytoma may include the following: - Surgery to remove the tumor, followed by chemotherapy and/or radiation therapy. - A clinical trial of a new treatment. Check the list of NCI-supported cancer clinical trials that are now accepting patients with childhood high-grade untreated astrocytoma or other tumor of glial origin. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your child's doctor about clinical trials that may be right for your child. General information about clinical trials is available from the NCI website. Recurrent Childhood High-Grade Astrocytomas When high-grade astrocytoma recurs after treatment, it usually comes back where the tumor first formed. Before more cancer treatment is given, imaging tests, biopsy, or surgery are done to find out if there is cancer and how much there is. Treatment of recurrent childhood high-grade astrocytoma may include the following: - Surgery to remove the tumor. - High-dose chemotherapy with stem cell transplant. - Targeted therapy with a BRAF inhibitor (vemurafenib or dabrafenib). - A clinical trial of targeted therapy with an immune checkpoint inhibitor. - A clinical trial of a new treatment.

information
What is (are) Childhood Non-Hodgkin Lymphoma ?
Key Points - Childhood non-Hodgkin lymphoma is a disease in which malignant (cancer) cells form in the lymph system. - The main types of lymphoma are Hodgkin lymphoma and non-Hodgkin lymphoma. - There are three major types of childhood non-Hodgkin lymphoma. - Mature B-cell non-Hodgkin lymphoma - Lymphoblastic lymphoma - Anaplastic large cell lymphoma - Some types of non-Hodgkin lymphoma are rare in children. - Past treatment for cancer and having a weakened immune system affect the risk of having childhood non-Hodgkin lymphoma. - Signs of childhood non-Hodgkin lymphoma include breathing problems and swollen lymph nodes. - Tests that examine the body and lymph system are used to detect (find) and diagnose childhood non-Hodgkin lymphoma. - A biopsy is done to diagnose childhood non-Hodgkin lymphoma. - Certain factors affect prognosis (chance of recovery) and treatment options. Childhood non-Hodgkin lymphoma is a disease in which malignant (cancer) cells form in the lymph system. Childhood non-Hodgkin lymphoma is a type of cancer that forms in the lymph system, which is part of the body's immune system. The immune system protects the body from foreign substances, infection, and diseases. The lymph system is made up of the following: - Lymph: Colorless, watery fluid that carries white blood cells called lymphocytes through the lymph system. Lymphocytes protect the body against infections and the growth of tumors. There are three types of lymphocytes: - B lymphocytes that make antibodies to help fight infection. - T lymphocytes that help B lymphocytes make the antibodies that help fight infection. - Natural killer cells that attack cancer cells and viruses. - Lymph vessels: A network of thin tubes that collect lymph from different parts of the body and return it to the bloodstream. - Lymph nodes: Small, bean-shaped structures that filter lymph and store white blood cells that help fight infection and disease. Lymph nodes are located along the network of lymph vessels found throughout the body. Clusters of lymph nodes are found in the neck, underarm, abdomen, pelvis, and groin. - Spleen: An organ that makes lymphocytes, filters the blood, stores blood cells, and destroys old blood cells. The spleen is on the left side of the abdomen near the stomach. - Thymus: An organ in which lymphocytes grow and multiply. The thymus is in the chest behind the breastbone. - Tonsils: Two small masses of lymph tissue at the back of the throat. The tonsils make lymphocytes. - Bone marrow: The soft, spongy tissue in the center of large bones. Bone marrow makes white blood cells, red blood cells, and platelets. Non-Hodgkin lymphoma can begin in B lymphocytes, T lymphocytes, or natural killer cells. Lymphocytes can also be found in the blood and collect in the lymph nodes, spleen, and thymus. Lymph tissue is also found in other parts of the body such as the stomach, thyroid gland, brain, and skin. Non-Hodgkin lymphoma can occur in both adults and children. Treatment for children is different than treatment for adults. See the following PDQ summaries for information about treatment of non-Hodgkin lymphoma in adults: - Adult Non-Hodgkin Lymphoma - Primary CNS Lymphoma Treatment - Mycosis Fungoides and the Sezary Syndrome Treatment The main types of lymphoma are Hodgkin lymphoma and non-Hodgkin lymphoma. Lymphomas are divided into two general types: Hodgkin lymphoma and non-Hodgkin lymphoma. This summary is about the treatment of childhood non-Hodgkin lymphoma. See the PDQ summary on Childhood Hodgkin Lymphoma Treatment for information about childhood Hodgkin lymphoma. There are three major types of childhood non-Hodgkin lymphoma. The type of lymphoma is determined by how the cells look under a microscope. The three major types of childhood non-Hodgkin lymphoma are: Mature B-cell non-Hodgkin lymphoma Mature B-cell non-Hodgkin lymphomas include: - Burkitt and Burkitt-like lymphoma/leukemia: Burkitt lymphoma and Burkitt leukemia are different forms of the same disease. Burkitt lymphoma/leukemia is an aggressive (fast-growing) disorder of B lymphocytes that is most common in children and young adults. It may form in the abdomen, Waldeyer's ring, testicles, bone, bone marrow, skin, or central nervous system (CNS). Burkitt leukemia may start in the lymph nodes as Burkitt lymphoma and then spread to the blood and bone marrow, or it may start in the blood and bone marrow without forming in the lymph nodes first. Both Burkitt leukemia and Burkitt lymphoma have been linked to infection with the Epstein-Barr virus (EBV), although EBV infection is more likely to occur in patients in Africa than in the United States. Burkitt and Burkitt-like lymphoma/leukemia are diagnosed when a sample of tissue is checked and a certain change to the c-myc gene is found. - Diffuse large B-cell lymphoma: Diffuse large B-cell lymphoma is the most common type of non-Hodgkin lymphoma. It is a type of B-cell non-Hodgkin lymphoma that grows quickly in the lymph nodes. The spleen, liver, bone marrow, or other organs are also often affected. Diffuse large B-cell lymphoma occurs more often in adolescents than in children. - Primary mediastinal B-cell lymphoma: A type of lymphoma that develops from B cells in the mediastinum (the area behind the breastbone). It may spread to nearby organs including the lungs and the sac around the heart. It may also spread to lymph nodes and distant organs including the kidneys. In children and adolescents, primary mediastinal B-cell lymphoma occurs more often in older adolescents. Lymphoblastic lymphoma Lymphoblastic lymphoma is a type of lymphoma that mainly affects T-cell lymphocytes. It usually forms in the mediastinum (the area behind the breastbone). This causes trouble breathing, wheezing, trouble swallowing, or swelling of the head and neck. It may spread to lymph nodes, bone, bone marrow, skin, the CNS, abdominal organs, and other areas. Lymphoblastic lymphoma is a lot like acute lymphoblastic leukemia (ALL). Anaplastic large cell lymphoma Anaplastic large cell lymphoma is a type of lymphoma that mainly affects T-cell lymphocytes. It usually forms in the lymph nodes, skin, or bone, and sometimes forms in the gastrointestinal tract, lung, tissue that covers the lungs, and muscle. Patients with anaplastic large cell lymphoma have a receptor, called CD30, on the surface of their T cells. In many children, anaplastic large cell lymphoma is marked by changes in the ALK gene that makes a protein called anaplastic lymphoma kinase. A pathologist checks for these cell and gene changes to help diagnose anaplastic large cell lymphoma. Some types of non-Hodgkin lymphoma are rare in children. Some types of childhood non-Hodgkin lymphoma are less common. These include: - Pediatric-type follicular lymphoma : In children, follicular lymphoma occurs mainly in males. It is more likely to be found in one area and does not spread to other places in the body. It usually forms in the tonsils and lymph nodes in the neck, but may also form in the testicles, kidney, gastrointestinal tract, and salivary gland. - Marginal zone lymphoma : Marginal zone lymphoma is a type of lymphoma that tends to grow and spread slowly and is usually found at an early stage. It may be found in the lymph nodes or in areas outside the lymph nodes. Marginal zone lymphoma found outside the lymph nodes in children is called mucosa-associated lymphoid tissue (MALT) lymphoma and may be linked to Helicobacter pylori infection of the gastrointestinal tract and Chlamydophila psittaci infection of the conjunctival membrane which lines the eye. - Primary central nervous system (CNS) lymphoma : Primary CNS lymphoma is extremely rare in children. - Peripheral T-cell lymphoma : Peripheral T-cell lymphoma is an aggressive (fast-growing) non-Hodgkin lymphoma that begins in mature T lymphocytes. The T lymphocytes mature in the thymus gland and travel to other parts of the lymph system, such as the lymph nodes, bone marrow, and spleen. - Cutaneous T-cell lymphoma : Cutaneous T-cell lymphoma begins in the skin and can cause the skin to thicken or form a tumor. It is very rare in children, but is more common in adolescents and young adults. There are different types of cutaneous T-cell lymphoma, such as cutaneous anaplastic large cell lymphoma, subcutaneous panniculitis-like T-cell lymphoma, gamma-delta T-cell lymphoma, and mycosis fungoides. Mycosis fungoides rarely occurs in children and adolescents. Past treatment for cancer and having a weakened immune system affect the risk of having childhood non-Hodgkin lymphoma. Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesnt mean that you will not get cancer. Talk with your child's doctor if you think your child may be at risk. Possible risk factors for childhood non-Hodgkin lymphoma include the following: - Past treatment for cancer. - Being infected with the Epstein-Barr virus or human immunodeficiency virus (HIV). - Having a weakened immune system after a transplant or from medicines given after a transplant. - Having certain inherited diseases of the immune system. If lymphoma or lymphoproliferative disease is linked to a weakened immune system from certain inherited diseases, HIV infection, a transplant or medicines given after a transplant, the condition is called lymphoproliferative disease associated with immunodeficiency. The different types of lymphoproliferative disease associated with immunodeficiency include: - Lymphoproliferative disease associated with primary immunodeficiency. - HIV-associated non-Hodgkin lymphoma. - Post-transplant lymphoproliferative disease.

exams and tests
How to diagnose Childhood Non-Hodgkin Lymphoma ?
Tests that examine the body and lymph system are used to detect (find) and diagnose childhood non-Hodgkin lymphoma. The following tests and procedures may be used: - Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken. - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body, including electrolytes, uric acid, blood urea nitrogen (BUN), creatinine, and liver function values. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. - Liver function tests : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by the liver. A higher than normal amount of a substance can be a sign of cancer. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. Sometimes a PET scan and a CT scan are done at the same time. If there is any cancer, this increases the chance that it will be found. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). - Lumbar puncture : A procedure used to collect cerebrospinal fluid (CSF) from the spinal column. This is done by placing a needle between two bones in the spine and into the CSF around the spinal cord and removing a sample of the fluid. The sample of CSF is checked under a microscope for signs that the cancer has spread to the brain and spinal cord. This procedure is also called an LP or spinal tap. - Chest x-ray : An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. - Ultrasound exam: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. The picture can be printed to be looked at later. - A biopsy is done to diagnose childhood non-Hodgkin lymphoma: Cells and tissues are removed during a biopsy so they can be viewed under a microscope by a pathologist to check for signs of cancer. Because treatment depends on the type of non-Hodgkin lymphoma, biopsy samples should be checked by a pathologist who has experience in diagnosing childhood non-Hodgkin lymphoma. One of the following types of biopsies may be done: - Excisional biopsy : The removal of an entire lymph node or lump of tissue. - Incisional biopsy : The removal of part of a lump, lymph node, or sample of tissue. - Core biopsy : The removal of tissue or part of a lymph node using a wide needle. - Fine-needle aspiration (FNA) biopsy : The removal of tissue or part of a lymph node using a thin needle. The procedure used to remove the sample of tissue depends on where the tumor is in the body: - Bone marrow aspiration and biopsy : The removal of bone marrow and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. - Mediastinoscopy : A surgical procedure to look at the organs, tissues, and lymph nodes between the lungs for abnormal areas. An incision (cut) is made at the top of the breastbone and a mediastinoscope is inserted into the chest. A mediastinoscope is a thin, tube-like instrument with a light and a lens for viewing. It also has a tool to remove tissue or lymph node samples, which are checked under a microscope for signs of cancer. - Anterior mediastinotomy : A surgical procedure to look at the organs and tissues between the lungs and between the breastbone and heart for abnormal areas. An incision (cut) is made next to the breastbone and a mediastinoscope is inserted into the chest. A mediastinoscope is a thin, tube-like instrument with a light and a lens for viewing. It also has a tool to remove tissue or lymph node samples, which are checked under a microscope for signs of cancer. This is also called the Chamberlain procedure. - Thoracentesis : The removal of fluid from the space between the lining of the chest and the lung, using a needle. A pathologist views the fluid under a microscope to look for cancer cells. If cancer is found, the following tests may be done to study the cancer cells: - Immunohistochemistry : A laboratory test that uses antibodies to check for certain antigens in a sample of tissue. The antibody is usually linked to a radioactive substance or a dye that causes the tissue to light up under a microscope. This type of test may be used to tell the difference between different types of cancer. - Flow cytometry : A laboratory test that measures the number of cells in a sample, the percentage of live cells in a sample, and certain characteristics of cells, such as size, shape, and the presence of tumor markers on the cell surface. The cells are stained with a light-sensitive dye, placed in a fluid, and passed in a stream before a laser or other type of light. The measurements are based on how the light-sensitive dye reacts to the light. - Cytogenetic analysis : A laboratory test in which cells in a sample of tissue are viewed under a microscope to look for certain changes in the chromosomes. - FISH (fluorescence in situ hybridization): A laboratory test used to look at genes or chromosomes in cells and tissues. Pieces of DNA that contain a fluorescent dye are made in the laboratory and added to cells or tissues on a glass slide. When these pieces of DNA attach to certain genes or areas of chromosomes on the slide, they light up when viewed under a microscope with a special light. This type of test is used to find certain gene changes. - Immunophenotyping : A laboratory test used to identify cells, based on the types of antigens or markers on the surface of the cell. This test is used to diagnose specific types of lymphoma by comparing the cancer cells to normal cells of the immune system.

outlook
What is the outlook for Childhood Non-Hodgkin Lymphoma ?
Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on: - The type of lymphoma. - Where the tumor is in the body when the tumor is diagnosed. - The stage of the cancer. - Whether there are certain changes in the chromosomes. - The type of initial treatment. - Whether the lymphoma responded to initial treatment. - The patients age and general health.

research
what research (or clinical trials) is being done for Childhood Non-Hodgkin Lymphoma ?
New types of treatment are being tested in clinical trials. Information about clinical trials is available from the NCI website. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.

Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.

stages
What are the stages of Childhood Non-Hodgkin Lymphoma ?
Key Points - After childhood non-Hodgkin lymphoma has been diagnosed, tests are done to find out if cancer cells have spread within the lymph system or to other parts of the body. - There are three ways that cancer spreads in the body. - The following stages are used for childhood non-Hodgkin lymphoma: - Stage I - Stage II - Stage III - Stage IV After childhood non-Hodgkin lymphoma has been diagnosed, tests are done to find out if cancer cells have spread within the lymph system or to other parts of the body. The process used to find out if cancer has spread within the lymph system or to other parts of the body is called staging. The results of tests and procedures used to diagnose non-Hodgkin lymphoma may also be used for staging. See the General Information section for a description of these tests and procedures. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The following procedure also may be used to determine the stage: - Bone scan : A procedure to check if there are rapidly dividing cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones with cancer and is detected by a scanner. There are three ways that cancer spreads in the body. Cancer can spread through tissue, the lymph system, and the blood: - Tissue. The cancer spreads from where it began by growing into nearby areas. - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body. - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body. The following stages are used for childhood non-Hodgkin lymphoma: Stage I In stage I childhood non-Hodgkin lymphoma, cancer is found: - in one group of lymph nodes; or - in one area outside the lymph nodes. No cancer is found in the abdomen or mediastinum (area between the lungs). Stage II In stage II childhood non-Hodgkin lymphoma, cancer is found: - in one area outside the lymph nodes and in nearby lymph nodes; or - in two or more areas either above or below the diaphragm, and may have spread to nearby lymph nodes; or - to have started in the stomach or intestines and can be completely removed by surgery. Cancer may have spread to certain nearby lymph nodes. Stage III In stage III childhood non-Hodgkin lymphoma, cancer is found: - in at least one area above the diaphragm and in at least one area below the diaphragm; or - to have started in the chest; or - to have started in the abdomen and spread throughout the abdomen; or - in the area around the spine. Stage IV In stage IV childhood non-Hodgkin lymphoma, cancer is found in the bone marrow, brain, or cerebrospinal fluid. Cancer may also be found in other parts of the body.

What are the treatments for Childhood Non-Hodgkin Lymphoma ?
Key Points - There are different types of treatment for children with non-Hodgkin lymphoma. - Children with non-Hodgkin lymphoma should have their treatment planned by a team of doctors who are experts in treating childhood cancer. - Some cancer treatments cause side effects months or years after treatment has ended. - Six types of standard treatment are used: - Chemotherapy - Radiation therapy - High-dose chemotherapy with stem cell transplant - Targeted therapy - Other drug therapy - Phototherapy - New types of treatment are being tested in clinical trials. - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for children with non-Hodgkin lymphoma. Different types of treatment are available for children with non-Hodgkin lymphoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Taking part in a clinical trial should be considered for all children with non-Hodgkin lymphoma. Some clinical trials are open only to patients who have not started treatment. Children with non-Hodgkin lymphoma should have their treatment planned by a team of doctors who are experts in treating childhood cancer. Treatment will be overseen by a pediatric oncologist, a doctor who specializes in treating children with cancer. The pediatric oncologist works with other health care providers who are experts in treating children with non-Hodgkin lymphoma and who specialize in certain areas of medicine. These may include the following specialists: - Pediatrician. - Radiation oncologist. - Pediatric hematologist. - Pediatric surgeon. - Pediatric nurse specialist. - Rehabilitation specialist. - Psychologist. - Social worker. Some cancer treatments cause side effects months or years after treatment has ended. Side effects from cancer treatment that begin during or after treatment and continue for months or years are called late effects. Late effects of cancer treatment may include the following: - Physical problems. - Changes in mood, feelings, thinking, learning, or memory. - Second cancers (new types of cancer). Some late effects may be treated or controlled. It is important to talk with your child's doctors about the effects cancer treatment can have on your child. (See the PDQ summary on Late Effects of Treatment for Childhood Cancer for more information.) Six types of standard treatment are used: Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid (intrathecal chemotherapy), an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas. Combination chemotherapy is treatment using two or more anticancer drugs. The way the chemotherapy is given depends on the type and stage of the cancer being treated. Intrathecal chemotherapy may be used to treat childhood non-Hodgkin lymphoma that has spread, or may spread, to the brain. When used to lessen the chance cancer will spread to the brain, it is called CNS prophylaxis. Intrathecal chemotherapy is given in addition to chemotherapy by mouth or vein. Higher than usual doses of chemotherapy may also be used as CNS prophylaxis. See Drugs Approved for Non-Hodgkin Lymphoma for more information. Radiation therapy Radiation therapy is a cancer treatment that uses high energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type of non-Hodgkin lymphoma being treated. External radiation therapy may be used to treat childhood non-Hodgkin lymphoma that has spread, or may spread, to the brain and spinal cord. Internal radiation therapy is not used to treat non-Hodgkin lymphoma. High-dose chemotherapy with stem cell transplant This treatment is a way of giving high doses of chemotherapy and then replacing blood -forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the bone marrow or blood of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the bodys blood cells. See Drugs Approved for Non-Hodgkin Lymphoma for more information. Targeted therapy Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Monoclonal antibodies, tyrosine kinase inhibitors, and immunotoxins are three types of targeted therapy being used or studied in the treatment of childhood non-Hodgkin lymphoma. Monoclonal antibody therapy is a cancer treatment that uses antibodies made in the laboratory from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. - Rituximab is used to treat several types of childhood non-Hodgkin lymphoma. - Brentuximab vedotin is a monoclonal antibody combined with an anticancer drug that is used to treat anaplastic large cell lymphoma. A bispecific monoclonal antibody is made up of two different monoclonal antibodies that bind to two different substances and kills cancer cells. Bispecific monoclonal antibody therapy is used in the treatment of Burkitt and Burkitt-like lymphoma /leukemia and diffuse large B-cell lymphoma. Tyrosine kinase inhibitors (TKIs) block signals that tumors need to grow. Some TKIs also keep tumors from growing by preventing the growth of new blood vessels to the tumors. Other types of kinase inhibitors, such as crizotinib, are being studied for childhood non-Hodgkin lymphoma. Immunotoxins can bind to cancer cells and kill them. Denileukin diftitox is an immunotoxin used to treat cutaneous T-cell lymphoma. See Drugs Approved for Non-Hodgkin Lymphoma for more information. Other drug therapy Retinoids are drugs related to vitamin A. Retinoid therapy with bexarotene is used to treat several types of cutaneous T-cell lymphoma. Steroids are hormones made naturally in the body. They can also be made in a laboratory and used as drugs. Steroid therapy is used to treat cutaneous T-cell lymphoma. Phototherapy Phototherapy is a cancer treatment that uses a drug and a certain type of laser light to kill cancer cells. A drug that is not active until it is exposed to light is injected into a vein. The drug collects more in cancer cells than in normal cells. For skin cancer in the skin, laser light is shined onto the skin and the drug becomes active and kills the cancer cells. Phototherapy is used in the treatment of cutaneous T-cell lymphoma. New types of treatment are being tested in clinical trials. Information about clinical trials is available from the NCI website. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your child's condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

What is (are) Endometrial Cancer ?
Key Points - Endometrial cancer is a disease in which malignant (cancer) cells form in the tissues of the endometrium. - Endometrial cancer is the most common invasive cancer of the female reproductive system. Endometrial cancer is a disease in which malignant (cancer) cells form in the tissues of the endometrium. The endometrium is the lining of the uterus. The uterus is part of the female reproductive system. It is a hollow, pear-shaped, muscular organ in the pelvis, where a fetus grows. Cancer of the endometrium is different from cancer of the muscle of the uterus, which is called sarcoma of the uterus. See the PDQ summary on Uterine Sarcoma Treatment for more information. See the following PDQ summaries for more information about endometrial cancer: - Endometrial Cancer Screening - Endometrial Cancer Treatment Endometrial cancer is the most common invasive cancer of the female reproductive system. Endometrial cancer is diagnosed most often in postmenopausal women at an average age of 60 years . From 2004 to 2013, the number of new cases of endometrial cancer increased slightly in white and African American women. From 2005 to 2014, the number of deaths from endometrial cancer also increased slightly in white and African American women. Compared with white women, rates of endometrial cancer are lower in Japanese Americans and in Latinas. The rates of endometrial cancer in white women are about the same as in African Americans or in native Hawaiians. The number of deaths from endometrial cancer is higher in African American women compared with women of other races.

How to prevent Endometrial Cancer ?
Key Points - Avoiding risk factors and increasing protective factors may help prevent cancer. - The following risk factors increase the risk of endometrial cancer: - Endometrial hyperplasia - Estrogen - Tamoxifen - Obesity, weight gain, metabolic syndrome, and diabetes - Genetic factors - The following protective factors decrease the risk of endometrial cancer: - Pregnancy and breast-feeding - Combination oral contraceptives - Physical activity - Cigarette smoking - It is not known if the following factors affect the risk of endometrial cancer: - Weight loss - Fruits, vegetables, and vitamins - Cancer prevention clinical trials are used to study ways to prevent cancer. - New ways to prevent endometrial cancer are being studied in clinical trials. Avoiding risk factors and increasing protective factors may help prevent cancer. Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer. The following risk factors increase the risk of endometrial cancer: Endometrial hyperplasia Endometrial hyperplasia is an abnormal thickening of the endometrium (lining of the uterus). It is not cancer, but in some cases, it may lead to endometrial cancer. Estrogen Estrogen is a hormone made by the body. It helps the body develop and maintain female sex characteristics. Estrogen can affect the growth of some cancers, including endometrial cancer. A woman's risk of developing endometrial cancer is increased by being exposed to estrogen in the following ways: - Estrogen-only hormone replacement therapy: Estrogen may be given to replace the estrogen no longer produced by the ovaries in postmenopausal women or women whose ovaries have been removed. This is called hormone replacement therapy (HRT), or hormone therapy (HT). The use of HRT that contains only estrogen increases the risk of endometrial cancer and endometrial hyperplasia. For this reason, estrogen therapy alone is usually prescribed only for women who do not have a uterus. HRT that contains only estrogen also increases the risk of stroke and blood clots. When estrogen is combined with progestin (another hormone), it is called combination estrogen-progestin replacement therapy. For postmenopausal women, taking estrogen in combination with progestin does not increase the risk of endometrial cancer, but it does increase the risk of breast cancer. (See the Breast Cancer Prevention summary for more information.) - Early menstruation: Beginning to have menstrual periods at an early age increases the number of years the body is exposed to estrogen and increases a woman's risk of endometrial cancer. - Late menopause: Women who reach menopause at an older age are exposed to estrogen for a longer time and have an increased risk of endometrial cancer. - Never being pregnant: Because estrogen levels are lower during pregnancy, women who have never been pregnant are exposed to estrogen for a longer time than women who have been pregnant. This increases the risk of endometrial cancer. Tamoxifen Tamoxifen is one of a group of drugs called selective estrogen receptor modulators, or SERMs. Tamoxifen acts like estrogen on some tissues in the body, such as the uterus, but blocks the effects of estrogen on other tissues, such as the breast. Tamoxifen is used to prevent breast cancer in women who are at high risk for the disease. However, using tamoxifen for more than 2 years increases the risk of endometrial cancer. This risk is greater in postmenopausal women. Raloxifene is a SERM that is used to prevent bone weakness in postmenopausal women. However, it does not have estrogen-like effects on the uterus and has not been shown to increase the risk of endometrial cancer. Obesity, weight gain, metabolic syndrome, and diabetes Obesity, gaining weight as an adult, or having metabolic syndrome increases the risk of endometrial cancer. Obesity is related to other risk factors such as high estrogen levels, having extra fat around the waist, polycystic ovary syndrome, and lack of physical activity. Having metabolic syndrome increases the risk of endometrial cancer. Metabolic syndrome is a condition that includes extra fat around the waist, high blood sugar, high blood pressure, and high levels of triglycerides (a type of fat) in the blood. Genetic factors Hereditary nonpolyposis colon cancer (HNPCC) syndrome (also known as Lynch Syndrome) is an inherited disorder caused by changes in certain genes. Women who have HNPCC syndrome have a much higher risk of developing endometrial cancer than women who do not have HNPCC syndrome. Polycystic ovary syndrome (a disorder of the hormones made by the ovaries), and Cowden syndrome are inherited conditions that are linked to an increased risk of endometrial cancer. Women with a family history of endometrial cancer in a first-degree relative (mother, sister, or daughter) are also at increased risk of endometrial cancer. The following protective factors decrease the risk of endometrial cancer: Pregnancy and breast-feeding Estrogen levels are lower during pregnancy and when breast-feeding. The risk of endometrial cancer is lower in women who have had children. Breastfeeding for more than 18 months also decreases the risk of endometrial cancer. Combination oral contraceptives Taking contraceptives that combine estrogen and progestin (combination oral contraceptives) decreases the risk of endometrial cancer. The protective effect of combination oral contraceptives increases with the length of time they are used, and can last for many years after oral contraceptive use has been stopped. While taking oral contraceptives, women have a higher risk of blood clots, stroke, and heart attack, especially women who smoke and are older than 35 years. Physical activity Physical activity at home (exercise) or on the job may lower the risk of endometrial cancer. Cigarette smoking Smoking at least 20 cigarettes a day may lower the risk of endometrial cancer. The risk of endometrial cancer is even lower in postmenopausal women who smoke. However, there are many proven harms of smoking. Cigarette smokers live about 10 years less than nonsmokers. Cigarette smokers also have an increased risk of the following: - Heart disease. - Head and neck cancers. - Lung cancer. - Bladder cancer. - Pancreatic cancer. It is not known if the following factors affect the risk of endometrial cancer: Weight loss It is not known if losing weight decreases the risk of endometrial cancer. Fruits, vegetables, and vitamins A diet that includes, fruits, vegetables, phytoestrogen, soy, and vitamin D has not been found to affect the risk of endometrial cancer. Taking multivitamins has little or no effect on the risk of common cancers, including endometrial cancer. Cancer prevention clinical trials are used to study ways to prevent cancer. Cancer prevention clinical trials are used to study ways to lower the risk of developing certain types of cancer. Some cancer prevention trials are conducted with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are conducted with people who have had cancer and are trying to prevent another cancer of the same type or to lower their chance of developing a new type of cancer. Other trials are done with healthy volunteers who are not known to have any risk factors for cancer. The purpose of some cancer prevention clinical trials is to find out whether actions people take can prevent cancer. These may include eating fruits and vegetables, exercising, quitting smoking, or taking certain medicines, vitamins, minerals, or food supplements. New ways to prevent endometrial cancer are being studied in clinical trials. Clinical trials are taking place in many parts of the country. Information about clinical trials can be found in the Clinical Trials section of the NCI website. Check NCI's list of cancer clinical trials for endometrial cancer prevention trials that are now accepting patients.

Some cancer prevention trials are conducted with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are conducted with people who have had cancer and are trying to prevent another cancer of the same type or to lower their chance of developing a new type of cancer. Other trials are done with healthy volunteers who are not known to have any risk factors for cancer. The purpose of some cancer prevention clinical trials is to find out whether actions people take can prevent cancer. These may include eating fruits and vegetables, exercising, quitting smoking, or taking certain medicines, vitamins, minerals, or food supplements. New ways to prevent endometrial cancer are being studied in clinical trials. Clinical trials are taking place in many parts of the country. Information about clinical trials can be found in the Clinical Trials section of the NCI website. Check NCI's list of cancer clinical trials for endometrial cancer prevention trials that are now accepting patients.

What is (are) Pituitary Tumors ?
Key Points - A pituitary tumor is a growth of abnormal cells in the tissues of the pituitary gland. - The pituitary gland hormones control many other glands in the body. - Having certain genetic conditions increases the risk of developing a pituitary tumor. - Signs of a pituitary tumor include problems with vision and certain physical changes. - Imaging studies and tests that examine the blood and urine are used to detect (find) and diagnose a pituitary tumor. - Certain factors affect prognosis (chance of recovery) and treatment options. A pituitary tumor is a growth of abnormal cells in the tissues of the pituitary gland. Pituitary tumors form in the pituitary gland, a pea-sized organ in the center of the brain, just above the back of the nose. The pituitary gland is sometimes called the "master endocrine gland" because it makes hormones that affect the way many parts of the body work. It also controls hormones made by many other glands in the body. Pituitary tumors are divided into three groups: - Benign pituitary adenomas: Tumors that are not cancer. These tumors grow very slowly and do not spread from the pituitary gland to other parts of the body. - Invasive pituitary adenomas: Benign tumors that may spread to bones of the skull or the sinus cavity below the pituitary gland. - Pituitary carcinomas: Tumors that are malignant (cancer). These pituitary tumors spread into other areas of the central nervous system (brain and spinal cord) or outside of the central nervous system. Very few pituitary tumors are malignant. Pituitary tumors may be either non-functioning or functioning. - Non-functioning pituitary tumors do not make extra amounts of hormones. - Functioning pituitary tumors make more than the normal amount of one or more hormones. Most pituitary tumors are functioning tumors. The extra hormones made by pituitary tumors may cause certain signs or symptoms of disease. The pituitary gland hormones control many other glands in the body. Hormones made by the pituitary gland include: - Prolactin: A hormone that causes a womans breasts to make milk during and after pregnancy. - Adrenocorticotropic hormone (ACTH): A hormone that causes the adrenal glands to make a hormone called cortisol. Cortisol helps control the use of sugar, protein, and fats in the body and helps the body deal with stress. - Growth hormone: A hormone that helps control body growth and the use of sugar and fat in the body. Growth hormone is also called somatotropin. - Thyroid-stimulating hormone: A hormone that causes the thyroid gland to make other hormones that control growth, body temperature, and heart rate. Thyroid-stimulating hormone is also called thyrotropin. - Luteinizing hormone (LH) and follicle-stimulating hormone (FSH): Hormones that control the menstrual cycle in women and the making of sperm in men.

Who is at risk for Pituitary Tumors? ?
Having certain genetic conditions increases the risk of developing a pituitary tumor.Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesnt mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Risk factors for pituitary tumors include having the following hereditary diseases: - Multiple endocrine neoplasia type 1 (MEN1) syndrome. - Carney complex. - Isolated familial acromegaly.

symptoms
What are the symptoms of Pituitary Tumors ?
Signs of a pituitary tumor include problems with vision and certain physical changes. Signs and symptoms can be caused by the growth of the tumor and/or by hormones the tumor makes or by other conditions. Some tumors may not cause signs or symptoms. Check with your doctor if you have any of these problems. Signs and symptoms of a non-functioning pituitary tumor Sometimes, a pituitary tumor may press on or damage parts of the pituitary gland, causing it to stop making one or more hormones. Too little of a certain hormone will affect the work of the gland or organ that the hormone controls. The following signs and symptoms may occur: - Headache. - Some loss of vision. - Loss of body hair. - In women, less frequent or no menstrual periods or no milk from the breasts. - In men, loss of facial hair, growth of breast tissue, and impotence. - In women and men, lower sex drive. - In children, slowed growth and sexual development. Most of the tumors that make LH and FSH do not make enough extra hormone to cause signs and symptoms. These tumors are considered to be non-functioning tumors. Signs and symptoms of a functioning pituitary tumor When a functioning pituitary tumor makes extra hormones, the signs and symptoms will depend on the type of hormone being made. Too much prolactin may cause: - Headache. - Some loss of vision. - Less frequent or no menstrual periods or menstrual periods with a very light flow. - Trouble becoming pregnant or an inability to become pregnant. - Impotence in men. - Lower sex drive. - Flow of breast milk in a woman who is not pregnant or breast-feeding. Too much ACTH may cause: - Headache. - Some loss of vision. - Weight gain in the face, neck, and trunk of the body, and thin arms and legs. - A lump of fat on the back of the neck. - Thin skin that may have purple or pink stretch marks on the chest or abdomen. - Easy bruising. - Growth of fine hair on the face, upper back, or arms. - Bones that break easily. - Anxiety, irritability, and depression. Too much growth hormone may cause: - Headache. - Some loss of vision. - In adults, acromegaly (growth of the bones in the face, hands, and feet). In children, the whole body may grow much taller and larger than normal. - Tingling or numbness in the hands and fingers. - Snoring or pauses in breathing during sleep. - Joint pain. - Sweating more than usual. - Dysmorphophobia (extreme dislike of or concern about one or more parts of the body). Too much thyroid-stimulating hormone may cause: - Irregular heartbeat. - Shakiness. - Weight loss. - Trouble sleeping. - Frequent bowel movements. - Sweating. Other general signs and symptoms of pituitary tumors: - Nausea and vomiting. - Confusion. - Dizziness. - Seizures. - Runny or "drippy" nose (cerebrospinal fluid that surrounds the brain and spinal cord leaks into the nose).

exams and tests
How to diagnose Pituitary Tumors ?
Imaging studies and tests that examine the blood and urine are used to detect (find) and diagnose a pituitary tumor. The following tests and procedures may be used: - Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken. - Eye exam: An exam to check vision and the general health of the eyes. - Visual field exam: An exam to check a persons field of vision (the total area in which objects can be seen). This test measures both central vision (how much a person can see when looking straight ahead) and peripheral vision (how much a person can see in all other directions while staring straight ahead). The eyes are tested one at a time. The eye not being tested is covered. - Neurological exam : A series of questions and tests to check the brain, spinal cord, and nerve function. The exam checks a persons mental status, coordination, and ability to walk normally, and how well the muscles, senses, and reflexes work. This may also be called a neuro exam or a neurologic exam. - MRI (magnetic resonance imaging) with gadolinium : A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the brain and spinal cord. A substance called gadolinium is injected into a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI). - Blood chemistry study : A procedure in which a blood sample is checked to measure the amounts of certain substances, such as glucose (sugar), released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. - Blood tests: Tests to measure the levels of testosterone or estrogen in the blood. A higher or lower than normal amount of these hormones may be a sign of pituitary tumor. - Twenty-four-hour urine test: A test in which urine is collected for 24 hours to measure the amounts of certain substances. An unusual (higher or lower than normal) amount of a substance can be a sign of disease in the organ or tissue that makes it. A higher than normal amount of the hormone cortisol may be a sign of a pituitary tumor and Cushing syndrome. - High-dose dexamethasone suppression test: A test in which one or more high doses of dexamethasone are given. The level of cortisol is checked from a sample of blood or from urine that is collected for three days. This test is done to check if the adrenal gland is making too much cortisol or if the pituitary gland is telling the adrenal glands to make too much cortisol. - Low-dose dexamethasone suppression test: A test in which one or more small doses of dexamethasone are given. The level of cortisol is checked from a sample of blood or from urine that is collected for three days. This test is done to check if the adrenal gland is making too much cortisol. - Venous sampling for pituitary tumors: A procedure in which a sample of blood is taken from veins coming from the pituitary gland. The sample is checked to measure the amount of ACTH released into the blood by the gland. Venous sampling may be done if blood tests show there is a tumor making ACTH, but the pituitary gland looks normal in the imaging tests. - Biopsy : The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. The following tests may be done on the sample of tissue that is removed: - Immunohistochemistry : A test that uses antibodies to check for certain antigens in a sample of tissue. The antibody is usually linked to a radioactive substance or a dye that causes the tissue to light up under a microscope. This type of test may be used to tell the difference between different types of cancer. - Immunocytochemistry : A test that uses antibodies to check for certain antigens in a sample of cells. The antibody is usually linked to a radioactive substance or a dye that causes the cells to light up under a microscope. This type of test may be used to tell the difference between different types of cancer. - Light and electron microscopy : A laboratory test in which cells in a sample of tissue are viewed under regular and high-powered microscopes to look for certain changes in the cells.

outlook
What is the outlook for Pituitary Tumors ?
Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) depends on the type of tumor and whether the tumor has spread into other areas of the central nervous system (brain and spinal cord) or outside of the central nervous system to other parts of the body. Treatment options depend on the following: - The type and size of the tumor. - Whether the tumor is making hormones. - Whether the tumor is causing problems with vision or other signs or symptoms. - Whether the tumor has spread into the brain around the pituitary gland or to other parts of the body. - Whether the tumor has just been diagnosed or has recurred (come back).

What are the stages of Pituitary Tumors ?
Key Points - Once a pituitary tumor has been diagnosed, tests are done to find out if it has spread within the central nervous system (brain and spinal cord) or to other parts of the body. - Pituitary tumors are described in several ways. Once a pituitary tumor has been diagnosed, tests are done to find out if it has spread within the central nervous system (brain and spinal cord) or to other parts of the body. The extent or spread of cancer is usually described as stages. There is no standard staging system for pituitary tumors. Once a pituitary tumor is found, tests are done to find out if the tumor has spread into the brain or to other parts of the body. The following test may be used: - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). Pituitary tumors are described in several ways. Pituitary tumors are described by their size and grade, whether or not they make extra hormones, and whether the tumor has spread to other parts of the body. The following sizes are used: - Microadenoma: The tumor is smaller than 1 centimeter. - Macroadenoma: The tumor is 1 centimeter or larger. Most pituitary adenomas are microadenomas. The grade of a pituitary tumor is based on how far it has grown into the surrounding area of the brain, including the sella (the bone at the base of the skull, where the pituitary gland sits).

treatment
What are the treatments for Pituitary Tumors ?
Key Points - There are different types of treatment for patients with pituitary tumors. - Four types of standard treatment are used: - Surgery - Radiation therapy - Drug therapy - Chemotherapy - New types of treatment are being tested in clinical trials. - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for patients with pituitary tumors. Different types of treatments are available for patients with pituitary tumors. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment. Four types of standard treatment are used: Surgery Many pituitary tumors can be removed by surgery using one of the following operations: - Transsphenoidal surgery: A type of surgery in which the instruments are inserted into part of the brain by going through an incision (cut) made under the upper lip or at the bottom of the nose between the nostrils and then through the sphenoid bone (a butterfly-shaped bone at the base of the skull) to reach the pituitary gland. The pituitary gland lies just above the sphenoid bone. - Endoscopic transsphenoidal surgery: A type of surgery in which an endoscope is inserted through an incision (cut) made at the back of the inside of the nose and then through the sphenoid bone to reach the pituitary gland. An endoscope is a thin, tube-like instrument with a light, a lens for viewing, and a tool for removing tumor tissue. - Craniotomy: Surgery to remove the tumor through an opening made in the skull. Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. Certain ways of giving radiation therapy can help keep radiation from damaging nearby healthy tissue. This type of radiation therapy may include the following: - Stereotactic radiosurgery: A rigid head frame is attached to the skull to keep the head still during the radiation treatment. A machine aims a single large dose of radiation directly at the tumor. This procedure does not involve surgery. It is also called stereotaxic radiosurgery, radiosurgery, and radiation surgery. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type of the cancer being treated. External radiation therapy is used to treat pituitary tumors. Drug therapy Drugs may be given to stop a functioning pituitary tumor from making too many hormones. Chemotherapy Chemotherapy may be used as palliative treatment for pituitary carcinomas, to relieve symptoms and improve the patient's quality of life. Chemotherapy uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type of the cancer being treated. New types of treatment are being tested in clinical trials. Information about clinical trials is available from the NCI website. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups. Treatment Options for Pituitary Tumors Non-functioning Pituitary Tumors Treatment may include the following: - Surgery (transsphenoidal surgery, if possible) to remove the tumor, followed by watchful waiting (closely monitoring a patients condition without giving any treatment until signs or symptoms appear or change). Radiation therapy is given if the tumor comes back. - Radiation therapy alone. Treatment for luteinizing hormone -producing and follicle-stimulating hormone -producing tumors is usually transsphenoidal surgery to remove the tumor. Prolactin-Producing Pituitary Tumors Treatment may include the following: - Drug therapy to stop the tumor from making prolactin and to stop the tumor from growing. - Surgery to remove the tumor (transsphenoidal surgery or craniotomy) when the tumor does not respond to drug therapy or when the patient cannot take the drug. - Radiation therapy. - Surgery followed by radiation therapy. ACTH-Producing Pituitary Tumors Treatment may include the following: - Surgery (usually transsphenoidal surgery) to remove the tumor, with or without radiation therapy. - Radiation therapy alone. - Drug therapy to stop the tumor from making ACTH. - A clinical trial of stereotactic radiation surgery. Growth HormoneProducing Pituitary Tumors Treatment may include the following: - Surgery (usually transsphenoidal or endoscopic transsphenoidal surgery) to remove the tumor, with or without radiation therapy. - Drug therapy to stop the tumor from making growth hormone. Thyroid-Stimulating HormoneProducing Tumors Treatment may include the following: - Surgery (usually transsphenoidal surgery) to remove the tumor, with or without radiation therapy. - Drug therapy to stop the tumor from making hormones. Pituitary Carcinomas Treatment of pituitary carcinomas is palliative, to relieve symptoms and improve the quality of life. Treatment may include the following: - Surgery (transsphenoidal surgery or craniotomy) to remove the cancer, with or without radiation therapy. - Drug therapy to stop the tumor from making hormones. - Chemotherapy. Recurrent Pituitary Tumors Treatment may include the following: - Radiation therapy. - A clinical trial of stereotactic radiation surgery.

What is (are) Testicular Cancer ?
Key Points - Testicular cancer is a disease in which malignant (cancer) cells form in the tissues of one or both testicles. - Testicular cancer is the most common cancer in men aged 15 to 34 years. - Testicular cancer can usually be cured. - A condition called cryptorchidism (an undescended testicle) is a risk factor for testicular cancer. Testicular cancer is a disease in which malignant (cancer) cells form in the tissues of one or both testicles. The testicles are 2 egg-shaped glands inside the scrotum (a sac of loose skin that lies directly below the penis). The testicles are held within the scrotum by the spermatic cord. The spermatic cord also contains the vas deferens and vessels and nerves of the testicles. The testicles are the male sex glands and make testosterone and sperm. Germ cells in the testicles make immature sperm. These sperm travel through a network of tubules (tiny tubes) and larger tubes into the epididymis (a long coiled tube next to the testicles). This is where the sperm mature and are stored. Almost all testicular cancers start in the germ cells. The two main types of testicular germ cell tumors are seminomas and nonseminomas. See the PDQ summary on Testicular Cancer Treatment for more information about testicular cancer.

Who is at risk for Testicular Cancer? ?
A condition called cryptorchidism (an undescended testicle) is a risk factor for testicular cancer. Anything that increases the chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. Talk to your doctor if you think you may be at risk. Risk factors for testicular cancer include the following: - Having cryptorchidism (an undescended testicle). - Having a testicle that is not normal, such as a small testicle that does not work the way it should. - Having testicular carcinoma in situ. - Being white. - Having a personal or family history of testicular cancer. - Having Klinefelter syndrome. Men who have cryptorchidism, a testicle that is not normal, or testicular carcinoma in situ have an increased risk of testicular cancer in one or both testicles, and need to be followed closely.

What is (are) Hairy Cell Leukemia ?
Key Points - Hairy cell leukemia is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell). - Leukemia may affect red blood cells, white blood cells, and platelets. - Gender and age may affect the risk of hairy cell leukemia. - Signs and symptoms of hairy cell leukemia include infections, tiredness, and pain below the ribs. - Tests that examine the blood and bone marrow are used to detect (find) and diagnose hairy cell leukemia. - Certain factors affect treatment options and prognosis (chance of recovery). Hairy cell leukemia is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell). Hairy cell leukemia is a cancer of the blood and bone marrow. This rare type of leukemia gets worse slowly or does not get worse at all. The disease is called hairy cell leukemia because the leukemia cells look "hairy" when viewed under a microscope. Leukemia may affect red blood cells, white blood cells, and platelets. Normally, the bone marrow makes blood stem cells (immature cells) that become mature blood cells over time. A blood stem cell may become a myeloid stem cell or a lymphoid stem cell. A myeloid stem cell becomes one of three types of mature blood cells: - Red blood cells that carry oxygen and other substances to all tissues of the body. - White blood cells that fight infection and disease. - Platelets that form blood clots to stop bleeding. A lymphoid stem cell becomes a lymphoblast cell and then into one of three types of lymphocytes (white blood cells): - B lymphocytes that make antibodies to help fight infection. - T lymphocytes that help B lymphocytes make antibodies to help fight infection. - Natural killer cells that attack cancer cells and viruses. In hairy cell leukemia, too many blood stem cells become lymphocytes. These lymphocytes are abnormal and do not become healthy white blood cells. They are also called leukemia cells. The leukemia cells can build up in the blood and bone marrow so there is less room for healthy white blood cells, red blood cells, and platelets. This may cause infection, anemia, and easy bleeding. Some of the leukemia cells may collect in the spleen and cause it to swell. This summary is about hairy cell leukemia. See the following PDQ summaries for information about other types of leukemia: - Adult Acute Lymphoblastic Leukemia Treatment. - Childhood Acute Lymphoblastic Leukemia Treatment. - Chronic Lymphocytic Leukemia Treatment. - Adult Acute Myeloid Leukemia Treatment. - Childhood Acute Myeloid Leukemia/Other Myeloid Malignancies Treatment. - Chronic Myelogenous Leukemia Treatment.

How to diagnose Hairy Cell Leukemia ?
Tests that examine the blood and bone marrow are used to detect (find) and diagnose hairy cell leukemia. The following tests and procedures may be used: - Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as a swollen spleen, lumps, or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken. - Complete blood count (CBC): A procedure in which a sample of blood is drawn and checked for the following: - The number of red blood cells, white blood cells, and platelets. - The amount of hemoglobin (the protein that carries oxygen) in the red blood cells. - The portion of the sample made up of red blood cells. - Peripheral blood smear : A procedure in which a sample of blood is checked for cells that look "hairy," the number and kinds of white blood cells, the number of platelets, and changes in the shape of blood cells. - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. - Bone marrow aspiration and biopsy : The removal of bone marrow, blood, and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. A pathologist views the bone marrow, blood, and bone under a microscope to look for signs of cancer. - Immunophenotyping : A laboratory test in which the antigens or markers on the surface of a blood or bone marrow cell are checked to see what type of cell it is. This test is done to diagnose the specific type of leukemia by comparing the cancer cells to normal cells of the immune system. - Flow cytometry : A laboratory test that measures the number of cells in a sample, the percentage of live cells in a sample, and certain characteristics of cells, such as size, shape, and the presence of tumor markers on the cell surface. The cells are stained with a light-sensitive dye, placed in a fluid, and passed in a stream before a laser or other type of light. The measurements are based on how the light-sensitive dye reacts to the light. - Cytogenetic analysis : A laboratory test in which cells in a sample of tissue are viewed under a microscope to look for certain changes in the chromosomes. - Gene mutation test: A laboratory test done on a bone marrow or blood sample to check for mutations in the BRAF gene. A BRAF gene mutation is often found in patients with hairy cell leukemia. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. A CT scan of the abdomen may be done to check for swollen lymph nodes or a swollen spleen.

outlook
What is the outlook for Hairy Cell Leukemia ?
Certain factors affect treatment options and prognosis (chance of recovery). The treatment options may depend on the following: - The number of hairy (leukemia) cells and healthy blood cells in the blood and bone marrow. - Whether the spleen is swollen. - Whether there are signs or symptoms of leukemia, such as infection. - Whether the leukemia has recurred (come back) after previous treatment. The prognosis (chance of recovery) depends on the following: - Whether the hairy cell leukemia does not grow or grows so slowly it does not need treatment. - Whether the hairy cell leukemia responds to treatment. Treatment often results in a long-lasting remission (a period during which some or all of the signs and symptoms of the leukemia are gone). If the leukemia returns after it has been in remission, retreatment often causes another remission.

What are the stages of Hairy Cell Leukemia ?
Key Points - There is no standard staging system for hairy cell leukemia. There is no standard staging system for hairy cell leukemia. Staging is the process used to find out how far the cancer has spread. Groups are used in place of stages for hairy cell leukemia. The disease is grouped as untreated, progressive, or refractory. Untreated hairy cell leukemia The hairy cell leukemia is newly diagnosed and has not been treated except to relieve signs or symptoms such as weight loss and infections. In untreated hairy cell leukemia, some or all of the following conditions occur: - Hairy (leukemia) cells are found in the blood and bone marrow. - The number of red blood cells, white blood cells, or platelets may be lower than normal. - The spleen may be larger than normal. Progressive hairy cell leukemia In progressive hairy cell leukemia, the leukemia has been treated with either chemotherapy or splenectomy (removal of the spleen) and one or both of the following conditions occur: - There is an increase in the number of hairy cells in the blood or bone marrow. - The number of red blood cells, white blood cells, or platelets in the blood is lower than normal.

research
what research (or clinical trials) is being done for Hairy Cell Leukemia ?
New types of treatment are being tested in clinical trials. Information about clinical trials is available from the NCI website. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.

What are the treatments for Hairy Cell Leukemia ?
Key Points - There are different types of treatment for patients with hairy cell leukemia. - Five types of standard treatment are used: - Watchful waiting - Chemotherapy - Biologic therapy - Surgery - Targeted therapy - New types of treatment are being tested in clinical trials. - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for patients with hairy cell leukemia. Different types of treatment are available for patients with hairy cell leukemia. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment. Five types of standard treatment are used: Watchful waiting Watchful waiting is closely monitoring a patient's condition, without giving any treatment until signs or symptoms appear or change. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated. Cladribine and pentostatin are anticancer drugs commonly used to treat hairy cell leukemia. These drugs may increase the risk of other types of cancer, especially Hodgkin lymphoma and non-Hodgkin lymphoma. Long-term follow up for second cancers is very important. Biologic therapy Biologic therapy is a cancer treatment that uses the patients immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the bodys natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy. Interferon alfa is a biologic agent commonly used to treat hairy cell leukemia. See Drugs Approved for Hairy Cell Leukemia for more information. Surgery Splenectomy is a surgical procedure to remove the spleen. Targeted therapy Targeted therapy is a treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Monoclonal antibody therapy is a type of targeted therapy used to treat hairy cell leukemia. Monoclonal antibody therapy uses antibodies made in the laboratory from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. A monoclonal antibody called rituximab may be used for certain patients with hairy cell leukemia. Other types of targeted therapies are being studied. New types of treatment are being tested in clinical trials. Information about clinical trials is available from the NCI website. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice.

Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups. Treatment Options for Hairy Cell Leukemia Untreated Hairy Cell Leukemia If the patient's blood cell counts are not too low and there are no signs or symptoms, treatment may not be needed and the patient is carefully watched for changes in his or her condition. If blood cell counts become too low or if signs or symptoms appear, initial treatment may include the following: - Chemotherapy. - Splenectomy. Check the list of NCI-supported cancer clinical trials that are now accepting patients with untreated hairy cell leukemia. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website. Progressive Hairy Cell Leukemia Treatment for progressive hairy cell leukemia may include the following: - Chemotherapy. - Biologic therapy. - Splenectomy. - A clinical trial of chemotherapy and targeted therapy with a monoclonal antibody (rituximab). Check the list of NCI-supported cancer clinical trials that are now accepting patients with progressive hairy cell leukemia, initial treatment. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website. Relapsed or Refractory Hairy Cell Leukemia Treatment of relapsed or refractory hairy cell leukemia may include the following: - Chemotherapy. - Biologic therapy. - Targeted therapy with a monoclonal antibody (rituximab). - High-dose chemotherapy. - A clinical trial of a new biologic therapy. - A clinical trial of a new targeted therapy. - A clinical trial of chemotherapy and targeted therapy with a monoclonal antibody (rituximab). Check the list of NCI-supported cancer clinical trials that are now accepting patients with refractory hairy cell leukemia. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug.

What is (are) Chronic Myelogenous Leukemia ?
Key Points - Chronic myelogenous leukemia is a disease in which the bone marrow makes too many white blood cells. - Leukemia may affect red blood cells, white blood cells, and platelets. - Signs and symptoms of chronic myelogenous leukemia include fever, night sweats, and tiredness. - Most people with CML have a gene mutation (change) called the Philadelphia chromosome. - Tests that examine the blood and bone marrow are used to detect (find) and diagnose chronic myelogenous leukemia. - Certain factors affect prognosis (chance of recovery) and treatment options. Chronic myelogenous leukemia is a disease in which the bone marrow makes too many white blood cells. Chronic myelogenous leukemia (also called CML or chronic granulocytic leukemia) is a slowly progressing blood and bone marrow disease that usually occurs during or after middle age, and rarely occurs in children. Leukemia may affect red blood cells, white blood cells, and platelets. Normally, the bone marrow makes blood stem cells (immature cells) that become mature blood cells over time. A blood stem cell may become a myeloid stem cell or a lymphoid stem cell. A lymphoid stem cell becomes a white blood cell. A myeloid stem cell becomes one of three types of mature blood cells: - Red blood cells that carry oxygen and other substances to all tissues of the body. - Platelets that form blood clots to stop bleeding. - Granulocytes (white blood cells) that fight infection and disease. In CML, too many blood stem cells become a type of white blood cell called granulocytes. These granulocytes are abnormal and do not become healthy white blood cells. They are also called leukemia cells. The leukemia cells can build up in the blood and bone marrow so there is less room for healthy white blood cells, red blood cells, and platelets. When this happens, infection, anemia, or easy bleeding may occur. This summary is about chronic myelogenous leukemia. See the following PDQ summaries for more information about leukemia: - Adult Acute Lymphoblastic Leukemia Treatment - Childhood Acute Lymphoblastic Leukemia Treatment - Adult Acute Myeloid Leukemia Treatment - Childhood Acute Myeloid Leukemia/Other Myeloid Malignancies Treatment - Chronic Lymphocytic Leukemia Treatment - Hairy Cell Leukemia Treatment

genetic changes
What are the genetic changes related to Chronic Myelogenous Leukemia ?
Most people with CML have a gene mutation (change) called the Philadelphia chromosome. Every cell in the body contains DNA (genetic material) that determines how the cell looks and acts. DNA is contained inside chromosomes. In CML, part of the DNA from one chromosome moves to another chromosome. This change is called the Philadelphia chromosome. It results in the bone marrow making an enzyme, called tyrosine kinase, that causes too many stem cells to become white blood cells (granulocytes or blasts). The Philadelphia chromosome is not passed from parent to child.

exams and tests
How to diagnose Chronic Myelogenous Leukemia ?
Tests that examine the blood and bone marrow are used to detect (find) and diagnose chronic myelogenous leukemia.. The following tests and procedures may be used: - Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease such as an enlarged spleen. A history of the patients health habits and past illnesses and treatments will also be taken. - Complete blood count (CBC) with differential : A procedure in which a sample of blood is drawn and checked for the following: - The number of red blood cells and platelets. - The number and type of white blood cells. - The amount of hemoglobin (the protein that carries oxygen) in the red blood cells. - The portion of the blood sample made up of red blood cells. - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. - Bone marrow aspiration and biopsy : The removal of bone marrow, blood, and a small piece of bone by inserting a needle into the hipbone or breastbone. A pathologist views the bone marrow, blood, and bone under a microscope to look for abnormal cells. One of the following tests may be done on the samples of blood or bone marrow tissue that are removed: - Cytogenetic analysis: A test in which cells in a sample of blood or bone marrow are viewed under a microscope to look for certain changes in the chromosomes, such as the Philadelphia chromosome. - FISH (fluorescence in situ hybridization): A laboratory technique used to look at genes or chromosomes in cells and tissues. Pieces of DNA that contain a fluorescent dye are made in the laboratory and added to cells or tissues on a glass slide. When these pieces of DNA bind to specific genes or areas of chromosomes on the slide, they light up when viewed under a microscope with a special light. - Reverse transcriptionpolymerase chain reaction (RTPCR): A laboratory test in which cells in a sample of tissue are studied using chemicals to look for certain changes in the structure or function of genes.

outlook
What is the outlook for Chronic Myelogenous Leukemia ?
Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on the following: - The patients age. - The phase of CML. - The amount of blasts in the blood or bone marrow. - The size of the spleen at diagnosis. - The patients general health.

stages
What are the stages of Chronic Myelogenous Leukemia ?
Key Points - After chronic myelogenous leukemia has been diagnosed, tests are done to find out if the cancer has spread. - Chronic myelogenous leukemia has 3 phases. - Chronic phase - Accelerated phase - Blastic phase After chronic myelogenous leukemia has been diagnosed, tests are done to find out if the cancer has spread. Staging is the process used to find out how far the cancer has spread. There is no standard staging system for chronic myelogenous leukemia (CML). Instead, the disease is classified by phase: chronic phase, accelerated phase, or blastic phase. It is important to know the phase in order to plan treatment. The information from tests and procedures done to detect (find) and diagnose chronic myelogenous leukemia is also used to plan treatment. Chronic myelogenous leukemia has 3 phases. As the amount of blast cells increases in the blood and bone marrow, there is less room for healthy white blood cells, red blood cells, and platelets. This may result in infections, anemia, and easy bleeding, as well as bone pain and pain or a feeling of fullness below the ribs on the left side. The number of blast cells in the blood and bone marrow and the severity of signs or symptoms determine the phase of the disease. Chronic phase In chronic phase CML, fewer than 10% of the cells in the blood and bone marrow are blast cells. Accelerated phase In accelerated phase CML, 10% to 19% of the cells in the blood and bone marrow are blast cells. Blastic phase In blastic phase CML, 20% or more of the cells in the blood or bone marrow are blast cells. When tiredness, fever, and an enlarged spleen occur during the blastic phase, it is called blast crisis.

High-dose chemotherapy with stem cell transplant High-dose chemotherapy with stem cell transplant is a method of giving high doses of chemotherapy and replacing blood-forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the bodys blood cells. See Drugs Approved for Chronic Myelogenous Leukemia for more information. Donor lymphocyte infusion (DLI) Donor lymphocyte infusion (DLI) is a cancer treatment that may be used after stem cell transplant. Lymphocytes (a type of white blood cell) from the stem cell transplant donor are removed from the donors blood and may be frozen for storage. The donors lymphocytes are thawed if they were frozen and then given to the patient through one or more infusions. The lymphocytes see the patients cancer cells as not belonging to the body and attack them. Surgery Splenectomy is surgery to remove the spleen.

What is (are) Lung Cancer ?
Key Points - Lung cancer is a disease in which malignant (cancer) cells form in the tissues of the lung. - Lung cancer is the leading cause of cancer death in the United States. - Different factors increase or decrease the risk of lung cancer. Lung cancer is a disease in which malignant (cancer) cells form in the tissues of the lung. The lungs are a pair of cone-shaped breathing organs inside the chest. The lungs bring oxygen into the body when breathing in and send carbon dioxide out of the body when breathing out. Each lung has sections called lobes. The left lung has two lobes. The right lung, which is slightly larger, has three. A thin membrane called the pleura surrounds the lungs. Two tubes called bronchi lead from the trachea (windpipe) to the right and left lungs. The bronchi are sometimes involved in lung cancer. Small tubes called bronchioles and tiny air sacs called alveoli make up the inside of the lungs. There are two types of lung cancer: small cell lung cancer and non-small cell lung cancer. See the following PDQ summaries for more information about lung cancer: - Lung Cancer Prevention - Non-Small Cell Lung Cancer Treatment - Small Cell Lung Cancer Treatment Lung cancer is the leading cause of cancer death in the United States. Lung cancer is the third most common type of non-skin cancer in the United States. Lung cancer is the leading cause of cancer death in men and in women.

Who is at risk for Lung Cancer? ?
Different factors increase or decrease the risk of lung cancer. Anything that increases your chance of getting a disease is called a risk factor. Anything that decreases your chance of getting a disease is called a protective factor. For information about risk factors and protective factors for lung cancer, see the PDQ summary on Lung Cancer Prevention. Key Points - Screening tests have risks. - The risks of lung cancer screening tests include the following: - Finding lung cancer may not improve health or help you live longer. - False-negative test results can occur. - False-positive test results can occur. - Chest x-rays and low-dose spiral CT scans expose the chest to radiation. - Talk to your doctor about your risk for lung cancer and your need for screening tests. Screening tests have risks. Decisions about screening tests can be difficult. Not all screening tests are helpful and most have risks. Before having any screening test, you may want to discuss the test with your doctor. It is important to know the risks of the test and whether it has been proven to reduce the risk of dying from cancer. The risks of lung cancer screening tests include the following: Finding lung cancer may not improve health or help you live longer. Screening may not improve your health or help you live longer if you have lung cancer that has already spread to other places in your body. When a screening test result leads to the diagnosis and treatment of a disease that may never have caused symptoms or become life-threatening, it is called overdiagnosis. It is not known if treatment of these cancers would help you live longer than if no treatment were given, and treatments for cancer may have serious side effects. Harms of treatment may happen more often in people who have medical problems caused by heavy or long-term smoking. False-negative test results can occur. Screening test results may appear to be normal even though lung cancer is present. A person who receives a false-negative test result (one that shows there is no cancer when there really is) may delay seeking medical care even if there are symptoms. False-positive test results can occur. Screening test results may appear to be abnormal even though no cancer is present. A false-positive test result (one that shows there is cancer when there really isn't) can cause anxiety and is usually followed by more tests (such as biopsy), which also have risks. A biopsy to diagnose lung cancer can cause part of the lung to collapse. Sometimes surgery is needed to reinflate the lung. Harms of diagnostic tests may happen more often in patients who have medical problems caused by heavy or long-term smoking. Chest x-rays and low-dose spiral CT scans expose the chest to radiation. Radiation exposure from chest x-rays and low-dose spiral CT scans may increase the risk of cancer. Younger people and people at low risk for lung cancer are more likely to develop lung cancer caused by radiation exposure. . Talk to your doctor about your risk for lung cancer and your need for screening tests. Talk to your doctor or other health care provider about your risk for lung cancer, whether a screening test is right for you, and about the benefits and harms of the screening test. You should take part in the decision about whether a screening test is right for you. (See the PDQ summary on Cancer Screening Overview for more information.)

What is (are) Renal Cell Cancer ?
Key Points - Renal cell cancer is a disease in which malignant (cancer) cells form in tubules of the kidney. - Smoking and misuse of certain pain medicines can affect the risk of renal cell cancer. - Signs of renal cell cancer include blood in the urine and a lump in the abdomen. - Tests that examine the abdomen and kidneys are used to detect (find) and diagnose renal cell cancer. - Certain factors affect prognosis (chance of recovery) and treatment options. Renal cell cancer is a disease in which malignant (cancer) cells form in tubules of the kidney. Renal cell cancer (also called kidney cancer or renal adenocarcinoma) is a disease in which malignant (cancer) cells are found in the lining of tubules (very small tubes) in the kidney. There are 2 kidneys, one on each side of the backbone, above the waist. Tiny tubules in the kidneys filter and clean the blood. They take out waste products and make urine. The urine passes from each kidney through a long tube called a ureter into the bladder. The bladder holds the urine until it passes through the urethra and leaves the body. Cancer that starts in the ureters or the renal pelvis (the part of the kidney that collects urine and drains it to the ureters) is different from renal cell cancer. (See the PDQ summary about Transitional Cell Cancer of the Renal Pelvis and Ureter Treatment for more information).

Key Points - After renal cell cancer has been diagnosed, tests are done to find out if cancer cells have spread within the kidney or to other parts of the body. - There are three ways that cancer spreads in the body. - Cancer may spread from where it began to other parts of the body. - The following stages are used for renal cell cancer: - Stage I - Stage II - Stage III - Stage IV After renal cell cancer has been diagnosed, tests are done to find out if cancer cells have spread within the kidney or to other parts of the body. The process used to find out if cancer has spread within the kidney or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The following tests and procedures may be used in the staging process: - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). - Chest x-ray : An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. There are three ways that cancer spreads in the body. Cancer can spread through tissue, the lymph system, and the blood: - Tissue. The cancer spreads from where it began by growing into nearby areas. - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body. - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body. Cancer may spread from where it began to other parts of the body. When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood. - Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body. - Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body. The metastatic tumor is the same type of cancer as the primary tumor. For example, if renal cell cancer spreads to the bone, the cancer cells in the bone are actually cancerous renal cells. The disease is metastatic renal cell cancer, not bone cancer. The following stages are used for renal cell cancer: Stage I In stage I, the tumor is 7 centimeters or smaller and is found only in the kidney. Stage II In stage II, the tumor is larger than 7 centimeters and is found only in the kidney. Stage III In stage III: - the tumor is any size and cancer is found only in the kidney and in 1 or more nearby lymph nodes; or - cancer is found in the main blood vessels of the kidney or in the layer of fatty tissue around the kidney. Cancer may be found in 1 or more nearby lymph nodes. Stage IV In stage IV, cancer has spread: - beyond the layer of fatty tissue around the kidney and may be found in the adrenal gland above the kidney with cancer, or in nearby lymph nodes; or - to other organs, such as the lungs, liver, bones, or brain, and may have spread to lymph nodes.

treatment
What are the treatments for Renal Cell Cancer ?
Key Points - There are different types of treatment for patients with renal cell cancer. - Five types of standard treatment are used: - Surgery - Radiation therapy - Chemotherapy - Biologic therapy - Targeted therapy - New types of treatment are being tested in clinical trials. - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for patients with renal cell cancer. Different types of treatments are available for patients with renal cell cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment. Five types of standard treatment are used: Surgery Surgery to remove part or all of the kidney is often used to treat renal cell cancer. The following types of surgery may be used: - Partial nephrectomy: A surgical procedure to remove the cancer within the kidney and some of the tissue around it. A partial nephrectomy may be done to prevent loss of kidney function when the other kidney is damaged or has already been removed. - Simple nephrectomy: A surgical procedure to remove the kidney only. - Radical nephrectomy: A surgical procedure to remove the kidney, the adrenal gland, surrounding tissue, and, usually, nearby lymph nodes. A person can live with part of 1 working kidney, but if both kidneys are removed or not working, the person will need dialysis (a procedure to clean the blood using a machine outside of the body) or a kidney transplant (replacement with a healthy donated kidney). A kidney transplant may be done when the disease is in the kidney only and a donated kidney can be found. If the patient has to wait for a donated kidney, other treatment is given as needed. When surgery to remove the cancer is not possible, a treatment called arterial embolization may be used to shrink the tumor. A small incision is made and a catheter (thin tube) is inserted into the main blood vessel that flows to the kidney. Small pieces of a special gelatin sponge are injected through the catheter into the blood vessel. The sponges block the blood flow to the kidney and prevent the cancer cells from getting oxygen and other substances they need to grow. Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy is used to treat renal cell cancer, and may also be used as palliative therapy to relieve symptoms and improve quality of life. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated. See Drugs Approved for Kidney (Renal Cell) Cancer for more information. Biologic therapy Biologic therapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy. The following types of biologic therapy are being used or studied in the treatment of renal cell cancer: - Nivolumab: Nivolumab is a monoclonal antibody that boosts the bodys immune response against renal cell cancer cells. - Interferon: Interferon affects the division of cancer cells and can slow tumor growth. - Interleukin-2 (IL-2): IL-2 boosts the growth and activity of many immune cells, especially lymphocytes (a type of white blood cell). Lymphocytes can attack and kill cancer cells. See Drugs Approved for Kidney (Renal Cell) Cancer for more information. Targeted therapy Targeted therapy uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Targeted therapy with antiangiogenic agents are used to treat advanced renal cell cancer. Antiangiogenic agents keep blood vessels from forming in a tumor, causing the tumor to starve and stop growing or to shrink. Monoclonal antibodies and kinase inhibitors are two types of antiangiogenic agents used to treat renal cell cancer. Monoclonal antibody therapy uses antibodies made in the laboratory, from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. Monoclonal antibodies used to treat renal cell cancer attach to and block substances that cause new blood vessels to form in tumors. Kinase inhibitors stop cells from dividing and may prevent the growth of new blood vessels that tumors need to grow. An mTOR inhibitor is a type of kinase inhibitor. Everolimus and temsirolimus are mTOR inhibitors used to treat advanced renal cell cancer. See Drugs Approved for Kidney (Renal Cell) Cancer for more information. New types of treatment are being tested in clinical trials. Information about clinical trials is available from the NCI website. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups. Treatment Options for Renal Cell Cancer Stage I Renal Cell Cancer Treatment of stage I renal cell cancer may include the following: - Surgery (radical nephrectomy, simple nephrectomy, or partial nephrectomy). - Radiation therapy as palliative therapy to relieve symptoms in patients who cannot have surgery. - Arterial embolization as palliative therapy. - A clinical trial of a new treatment.

information
What is (are) Thymoma and Thymic Carcinoma ?
Key Points - Thymoma and thymic carcinoma are diseases in which malignant (cancer) cells form on the outside surface of the thymus. - Thymoma is linked with myasthenia gravis and other autoimmune diseases. - Signs and symptoms of thymoma and thymic carcinoma include a cough and chest pain. - Tests that examine the thymus are used to detect (find) thymoma or thymic carcinoma. - Thymoma and thymic carcinoma are usually diagnosed, staged, and treated during surgery. - Certain factors affect prognosis (chance of recovery) and treatment options. Thymoma and thymic carcinoma are diseases in which malignant (cancer) cells form on the outside surface of the thymus. The thymus, a small organ that lies in the upper chest under the breastbone, is part of the lymph system. It makes white blood cells, called lymphocytes, that protect the body against infections. There are different types of tumors of the thymus. Thymomas and thymic carcinomas are rare tumors of the cells that are on the outside surface of the thymus. The tumor cells in a thymoma look similar to the normal cells of the thymus, grow slowly, and rarely spread beyond the thymus. On the other hand, the tumor cells in a thymic carcinoma look very different from the normal cells of the thymus, grow more quickly, and have usually spread to other parts of the body when the cancer is found. Thymic carcinoma is more difficult to treat than thymoma. For information on thymoma and thymic carcinoma in children, see the PDQ summary on Unusual Cancers of Childhood Treatment. Thymoma is linked with myasthenia gravis and other autoimmune diseases. People with thymoma often have autoimmune diseases as well. These diseases cause the immune system to attack healthy tissue and organs. They include: - Myasthenia gravis. - Acquired pure red cell aplasia. - Hypogammaglobulinemia. - Polymyositis. - Lupus erythematosus. - Rheumatoid arthritis. - Thyroiditis. - Sjgren syndrome.

exams and tests
How to diagnose Thymoma and Thymic Carcinoma ?
Tests that examine the thymus are used to detect (find) thymoma or thymic carcinoma. The following tests and procedures may be used: - Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken. - Chest x-ray: An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the chest, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body, such as the chest. This procedure is also called nuclear magnetic resonance imaging (NMRI). - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. Thymoma and thymic carcinoma are usually diagnosed, staged, and treated during surgery. A biopsy of the tumor is done to diagnose the disease. The biopsy may be done before or during surgery (a mediastinoscopy or mediastinotomy), using a thin needle to remove a sample of cells. This is called a fine-needle aspiration (FNA) biopsy. Sometimes a wide needle is used to remove a sample of cells and this is called a core biopsy. A pathologist will view the sample under a microscope to check for cancer. If thymoma or thymic carcinoma is diagnosed, the pathologist will determine the type of cancer cell in the tumor. There may be more than one type of cancer cell in a thymoma. The surgeon will decide if all or part of the tumor can be removed by surgery. In some cases, lymph nodes and other tissues may be removed as well.

outlook
What is the outlook for Thymoma and Thymic Carcinoma ?
Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on the following: - The stage of the cancer. - The type of cancer cell. - Whether the tumor can be removed completely by surgery. - The patient's general health. - Whether the cancer has just been diagnosed or has recurred (come back).

stages
What are the stages of Thymoma and Thymic Carcinoma ?
Key Points - Tests done to detect thymoma or thymic carcinoma are also used to stage the disease. - There are three ways that cancer spreads in the body. - Cancer may spread from where it began to other parts of the body. - The following stages are used for thymoma: - Stage I - Stage II - Stage III - Stage IV - Thymic carcinomas have usually spread to other parts of the body when diagnosed. Tests done to detect thymoma or thymic carcinoma are also used to stage the disease. Staging is the process used to find out if cancer has spread from the thymus to other parts of the body. The findings made during surgery and the results of tests and procedures are used to determine the stage of the disease. It is important to know the stage in order to plan treatment. There are three ways that cancer spreads in the body. Cancer can spread through tissue, the lymph system, and the blood: - Tissue. The cancer spreads from where it began by growing into nearby areas. - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body. - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body. Cancer may spread from where it began to other parts of the body. When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood. - Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body. - Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body. The metastatic tumor is the same type of cancer as the primary tumor. For example, if thymic carcinoma spreads to the bone, the cancer cells in the bone are actually thymic carcinoma cells. The disease is metastatic thymic carcinoma, not bone cancer. The following stages are used for thymoma: Stage I In stage I, cancer is found only within the thymus. All cancer cells are inside the capsule (sac) that surrounds the thymus. Stage II In stage II, cancer has spread through the capsule and into the fat around the thymus or into the lining of the chest cavity. Stage III In stage III, cancer has spread to nearby organs in the chest, including the lung, the sac around the heart, or large blood vessels that carry blood to the heart. Stage IV Stage IV is divided into stage IVA and stage IVB, depending on where the cancer has spread. - In stage IVA, cancer has spread widely around the lungs and heart. - In stage IVB, cancer has spread to the blood or lymph system. Thymic carcinomas have usually spread to other parts of the body when diagnosed. The staging system used for thymomas is sometimes used for thymic carcinomas.

What are the treatments for Thymoma and Thymic Carcinoma ?
Key Points - There are different types of treatment for patients with thymoma and thymic carcinoma. - Four types of standard treatment are used: - Surgery - Radiation therapy - Chemotherapy - Hormone therapy - New types of treatment are being tested in clinical trials. - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for patients with thymoma and thymic carcinoma. Different types of treatments are available for patients with thymoma and thymic carcinoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.

The way the chemotherapy is given depends on the type and stage of the cancer being treated. Chemotherapy may be used to shrink the tumor before surgery or radiation therapy. This is called neoadjuvant chemotherapy. Hormone therapy Hormone therapy is a cancer treatment that removes hormones or blocks their action and stops cancer cells from growing. Hormones are substances produced by glands in the body and circulated in the bloodstream. Some hormones can cause certain cancers to grow. If tests show that the cancer cells have places where hormones can attach (receptors), drugs, surgery, or radiation therapy is used to reduce the production of hormones or block them from working. Hormone therapy with drugs called corticosteroids may be used to treat thymoma or thymic carcinoma. New types of treatment are being tested in clinical trials.

What is (are) Metastatic Squamous Neck Cancer with Occult Primary ?
Key Points - Metastatic squamous neck cancer with occult primary is a disease in which squamous cell cancer spreads to lymph nodes in the neck and it is not known where the cancer first formed in the body. - Signs and symptoms of metastatic squamous neck cancer with occult primary include a lump or pain in the neck or throat. - Tests that examine the tissues of the neck, respiratory tract, and upper part of the digestive tract are used to detect (find) and diagnose metastatic squamous neck cancer and the primary tumor. - Certain factors affect prognosis (chance of recovery) and treatment options. Metastatic squamous neck cancer with occult primary is a disease in which squamous cell cancer spreads to lymph nodes in the neck and it is not known where the cancer first formed in the body. Squamous cells are thin, flat cells found in tissues that form the surface of the skin and the lining of body cavities such as the mouth, hollow organs such as the uterus and blood vessels, and the lining of the respiratory (breathing) and digestive tracts. Some organs with squamous cells are the esophagus, lungs, kidneys, and uterus. Cancer can begin in squamous cells anywhere in the body and metastasize (spread) through the blood or lymph system to other parts of the body. When squamous cell cancer spreads to lymph nodes in the neck or around the collarbone, it is called metastatic squamous neck cancer. The doctor will try to find the primary tumor (the cancer that first formed in the body), because treatment for metastatic cancer is the same as treatment for the primary tumor. For example, when lung cancer spreads to the neck, the cancer cells in the neck are lung cancer cells and they are treated the same as the cancer in the lung. Sometimes doctors cannot find where in the body the cancer first began to grow. When tests cannot find a primary tumor, it is called an occult (hidden) primary tumor. In many cases, the primary tumor is never found.

exams and tests
How to diagnose Metastatic Squamous Neck Cancer with Occult Primary ?
Tests that examine the tissues of the neck, respiratory tract, and upper part of the digestive tract are used to detect (find) and diagnose metastatic squamous neck cancer and the primary tumor. Tests will include checking for a primary tumor in the organs and tissues of the respiratory tract (part of the trachea), the upper part of the digestive tract (including the lips, mouth, tongue, nose, throat, vocal cords, and part of the esophagus), and the genitourinary system. The following procedures may be used: - Physical exam and history : An exam of the body, especially the head and neck, to check general signs of health. This includes checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken. - Biopsy : The removal of cells or tissues so they can be viewed under a microscope by a pathologist or tested in the laboratory to check for signs of cancer. Three types of biopsy may be done: - Fine-needle aspiration (FNA) biopsy : The removal of tissue or fluid using a thin needle. - Core needle biopsy : The removal of tissue using a wide needle. - Excisional biopsy : The removal of an entire lump of tissue. The following procedures are used to remove samples of cells or tissue: - Tonsillectomy: Surgery to remove both tonsils. - Endoscopy : A procedure to look at organs and tissues inside the body to check for abnormal areas. An endoscope is inserted through an incision (cut) in the skin or opening in the body, such as the mouth or nose. An endoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove abnormal tissue or lymph node samples, which are checked under a microscope for signs of disease. The nose, throat, back of the tongue, esophagus, stomach, voice box, windpipe, and large airways will be checked. One or more of the following laboratory tests may be done to study the tissue samples: - Immunohistochemistry : A test that uses antibodies to check for certain antigens in a sample of blood or bone marrow. The antibody is usually linked to a radioactive substance or a dye that causes the tissue to light up under a microscope. This type of test may be used to tell the difference between different types of cancer. - Light and electron microscopy : A test in which cells in a sample of tissue are viewed under regular and high-powered microscopes to look for certain changes in the cells. - Epstein-Barr virus (EBV) and human papillomavirus (HPV) test: A test that checks the cells in a sample of tissue for EBV and HPV DNA. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. A whole body PET scan and a CT scan are done at the same time to look for where the cancer first formed. If there is any cancer, this increases the chance that it will be found. A diagnosis of occult primary tumor is made if the primary tumor is not found during testing or treatment.

outlook
What is the outlook for Metastatic Squamous Neck Cancer with Occult Primary ?
Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on the following: - The number and size of lymph nodes that have cancer in them. - Whether the cancer has responded to treatment or has recurred (come back). - How different from normal the cancer cells look under a microscope. - The patient's age and general health. Treatment options also depend on the following: - Which part of the neck the cancer is in. - Whether certain tumor markers are found.

stages
What are the stages of Metastatic Squamous Neck Cancer with Occult Primary ?
Key Points - After metastatic squamous neck cancer with occult primary has been diagnosed, tests are done to find out if cancer cells have spread to other parts of the body. - There are three ways that cancer spreads in the body. After metastatic squamous neck cancer with occult primary has been diagnosed, tests are done to find out if cancer cells have spread to other parts of the body. The process used to find out if cancer has spread to other parts of the body is called staging. The results from tests and procedures used to detect and diagnose the primary tumor are also used to find out if cancer has spread to other parts of the body. There is no standard staging system for metastatic squamous neck cancer with occult primary. The tumors are described as untreated or recurrent. Untreated metastatic squamous neck cancer with occult primary is cancer that is newly diagnosed and has not been treated, except to relieve signs and symptoms caused by the cancer. There are three ways that cancer spreads in the body. Cancer can spread through tissue, the lymph system, and the blood: - Tissue. The cancer spreads from where it began by growing into nearby areas. - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body. - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.

treatment
What are the treatments for Metastatic Squamous Neck Cancer with Occult Primary ?
Key Points - There are different types of treatment for patients with metastatic squamous neck cancer with occult primary. - Two types of standard treatment are used: - Surgery - Radiation therapy - New types of treatment are being tested in clinical trials. - Chemotherapy - Hyperfractionated radiation therapy - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for patients with metastatic squamous neck cancer with occult primary. Different types of treatment are available for patients with metastatic squamous neck cancer with occult primary. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment. Two types of standard treatment are used: Surgery Surgery may include neck dissection. There are different types of neck dissection, based on the amount of tissue that is removed. - Radical neck dissection: Surgery to remove tissues in one or both sides of the neck between the jawbone and the collarbone, including the following: - All lymph nodes. - The jugular vein. - Muscles and nerves that are used for face, neck, and shoulder movement, speech, and swallowing. The patient may need physical therapy of the throat, neck, shoulder, and/or arm after radical neck dissection. Radical neck dissection may be used when cancer has spread widely in the neck. - Modified radical neck dissection: Surgery to remove all the lymph nodes in one or both sides of the neck without removing the neck muscles. The nerves and/or the jugular vein may be removed. - Partial neck dissection: Surgery to remove some of the lymph nodes in the neck. This is also called selective neck dissection. Even if the doctor removes all the cancer that can be seen at the time of surgery, some patients may be given radiation therapy after surgery to kill any cancer cells that are left. Treatment given after surgery, to lower the risk that the cancer will come back, is called adjuvant therapy. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. Certain ways of giving radiation therapy can help keep radiation from damaging nearby healthy tissue. This type of radiation therapy may include the following: - Intensity-modulated radiation therapy (IMRT): IMRT is a type of 3-dimensional (3-D) radiation therapy that uses a computer to make pictures of the size and shape of the tumor. Thin beams of radiation of different intensities (strengths) are aimed at the tumor from many angles. This type of radiation therapy is less likely to cause dry mouth, trouble swallowing, and damage to the skin. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type of cancer being treated. External radiation therapy is used to treat metastatic squamous neck cancer with occult primary. Radiation therapy to the neck may change the way the thyroid gland works. Blood tests may be done to check the thyroid hormone level in the body before treatment and at regular checkups after treatment. New types of treatment are being tested in clinical trials. This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). Hyperfractionated radiation therapy Hyperfractionated radiation therapy is a type of external radiation treatment in which a smaller than usual total daily dose of radiation is divided into two doses and the treatments are given twice a day. Hyperfractionated radiation therapy is given over the same period of time (days or weeks) as standard radiation therapy. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups. Treatment Options for Metastatic Squamous Neck Cancer with Occult Primary Untreated Metastatic Squamous Neck Cancer with Occult Primary Treatment of untreated metastatic squamous neck cancer with occult primary may include the following: - Radiation therapy. - Surgery. - Radiation therapy followed by surgery. - A clinical trial of chemotherapy followed by radiation therapy. - A clinical trial of chemotherapy given at the same time as hyperfractionated radiation therapy. - Clinical trials of new treatments.

What is (are) Myelodysplastic/ Myeloproliferative Neoplasm, Unclassifiable ?
Key Points - Myelodysplastic/myeloproliferative neoplasm, unclassifiable, is a disease that has features of both myelodysplastic and myeloproliferative diseases but is not chronic myelomonocytic leukemia, juvenile myelomonocytic leukemia, or atypical chronic myelogenous leukemia. - Signs and symptoms of myelodysplastic/myeloproliferative neoplasm, unclassifiable, include fever, weight loss, and feeling very tired. Myelodysplastic/myeloproliferative neoplasm, unclassifiable, is a disease that has features of both myelodysplastic and myeloproliferative diseases but is not chronic myelomonocytic leukemia, juvenile myelomonocytic leukemia, or atypical chronic myelogenous leukemia. In myelodysplastic /myeloproliferative neoplasm, unclassifiable (MDS/MPD-UC), the body tells too many blood stem cells to become red blood cells, white blood cells, or platelets. Some of these blood stem cells never become mature blood cells. These immature blood cells are called blasts. Over time, the abnormal blood cells and blasts in the bone marrow crowd out the healthy red blood cells, white blood cells, and platelets. MDS/MPN-UC is a very rare disease. Because it is so rare, the factors that affect risk and prognosis are not known.

What is (are) Chronic Myeloproliferative Neoplasms ?
Key Points - Myeloproliferative neoplasms are a group of diseases in which the bone marrow makes too many red blood cells, white blood cells, or platelets. - There are 6 types of chronic myeloproliferative neoplasms. - Tests that examine the blood and bone marrow are used to detect (find) and diagnose chronic myeloproliferative neoplasms. Myeloproliferative neoplasms are a group of diseases in which the bone marrow makes too many red blood cells, white blood cells, or platelets. Normally, the bone marrow makes blood stem cells (immature cells) that become mature blood cells over time. A blood stem cell may become a myeloid stem cell or a lymphoid stem cell. A lymphoid stem cell becomes a white blood cell. A myeloid stem cell becomes one of three types of mature blood cells: - Red blood cells that carry oxygen and other substances to all tissues of the body. - White blood cells that fight infection and disease. - Platelets that form blood clots to stop bleeding. In myeloproliferative neoplasms, too many blood stem cells become one or more types of blood cells. The neoplasms usually get worse slowly as the number of extra blood cells increases. There are 6 types of chronic myeloproliferative neoplasms. The type of myeloproliferative neoplasm is based on whether too many red blood cells, white blood cells, or platelets are being made. Sometimes the body will make too many of more than one type of blood cell, but usually one type of blood cell is affected more than the others are. Chronic myeloproliferative neoplasms include the following 6 types: - Chronic myelogenous leukemia. - Polycythemia vera. - Primary myelofibrosis (also called chronic idiopathic myelofibrosis). - Essential thrombocythemia. - Chronic neutrophilic leukemia. - Chronic eosinophilic leukemia. These types are described below. Chronic myeloproliferative neoplasms sometimes become acute leukemia, in which too many abnormal white blood cells are made.

exams and tests
How to diagnose Chronic Myeloproliferative Neoplasms ?
Tests that examine the blood and bone marrow are used to detect (find) and diagnose chronic myeloproliferative neoplasms. The following tests and procedures may be used: - Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken. - Complete blood count (CBC) with differential : A procedure in which a sample of blood is drawn and checked for the following: - The number of red blood cells and platelets. - The number and type of white blood cells. - The amount of hemoglobin (the protein that carries oxygen) in the red blood cells. - The portion of the blood sample made up of red blood cells. - Peripheral blood smear : A procedure in which a sample of blood is checked for the following: - Whether there are red blood cells shaped like teardrops. - The number and kinds of white blood cells. - The number of platelets. - Whether there are blast cells. - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. - Bone marrow aspiration and biopsy : The removal of bone marrow, blood, and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. A pathologist views the bone marrow, blood, and bone under a microscope to look for abnormal cells. - Cytogenetic analysis : A test in which cells in a sample of blood or bone marrow are viewed under a microscope to look for certain changes in the chromosomes. Certain diseases or disorders may be diagnosed or ruled out based on the chromosomal changes. - Gene mutation test: A laboratory test done on a bone marrow or blood sample to check for mutations in JAK2 , MPL , or CALR genes. A JAK2 gene mutation is often found in patients with polycythemia vera, essential thrombocythemia, or primary myelofibrosis. MPL or CALR gene mutations are found in patients with essential thrombocythemia or primary myelofibrosis.

What are the treatments for Chronic Myeloproliferative Neoplasms ?
Key Points - There are different types of treatment for patients with chronic myeloproliferative neoplasms. - Eleven types of standard treatment are used: - Watchful waiting - Phlebotomy - Platelet apheresis - Transfusion therapy - Chemotherapy - Radiation therapy - Other drug therapy - Surgery - Biologic therapy - Targeted therapy - High-dose chemotherapy with stem cell transplant - New types of treatment are being tested in clinical trials. - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for patients with chronic myeloproliferative neoplasms. Different types of treatments are available for patients with chronic myeloproliferative neoplasms. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment. Eleven types of standard treatment are used: Watchful waiting Watchful waiting is closely monitoring a patients condition without giving any treatment until signs or symptoms appear or change. Phlebotomy Phlebotomy is a procedure in which blood is taken from a vein. A sample of blood may be taken for tests such as a CBC or blood chemistry. Sometimes phlebotomy is used as a treatment and blood is taken from the body to remove extra red blood cells. Phlebotomy is used in this way to treat some chronic myeloproliferative neoplasms. Platelet apheresis Platelet apheresis is a treatment that uses a special machine to remove platelets from the blood. Blood is taken from the patient and put through a blood cell separator where the platelets are removed. The rest of the blood is then returned to the patients bloodstream. Transfusion therapy Transfusion therapy (blood transfusion) is a method of giving red blood cells, white blood cells, or platelets to replace blood cells destroyed by disease or cancer treatment. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated. See Drugs Approved for Myeloproliferative Neoplasms for more information. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type of cancer being treated. External radiation therapy is used to treat chronic myeloproliferative neoplasms, and is usually directed at the spleen. Other drug therapy Prednisone and danazol are drugs that may be used to treat anemia in patients with primary myelofibrosis. Anagrelide therapy is used to reduce the risk of blood clots in patients who have too many platelets in their blood. Low-dose aspirin may also be used to reduce the risk of blood clots. Thalidomide, lenalidomide, and pomalidomide are drugs that prevent blood vessels from growing into areas of tumor cells. See Drugs Approved for Myeloproliferative Neoplasms for more information. Surgery Splenectomy (surgery to remove the spleen) may be done if the spleen is enlarged. Biologic therapy Biologic therapy is a treatment that uses the patient's immune system to fight cancer or other diseases. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against disease. This type of treatment is also called biotherapy or immunotherapy. Interferon alfa and pegylated interferon alpha are biologic agents commonly used to treat some chronic myeloproliferative neoplasms. Erythropoietic growth factors are also biologic agents. They are used to stimulate the bone marrow to make red blood cells. Targeted therapy Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Tyrosine kinase inhibitors are targeted therapy drugs that block signals needed for tumors to grow. Ruxolitinib is a tyrosine kinase inhibitor used to treat certain types of myelofibrosis. See Drugs Approved for Myeloproliferative Neoplasms for more information. Other types of targeted therapies are being studied in clinical trials. High-dose chemotherapy with stem cell transplant High-dose chemotherapy with stem cell transplant is a method of giving high doses of chemotherapy and replacing blood-forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body's blood cells. New types of treatment are being tested in clinical trials. Information about clinical trials is available from the NCI website. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

What is (are) Adult Acute Myeloid Leukemia ?
Key Points - Adult acute myeloid leukemia (AML) is a type of cancer in which the bone marrow makes abnormal myeloblasts (a type of white blood cell), red blood cells, or platelets. - Leukemia may affect red blood cells, white blood cells, and platelets. - There are different subtypes of AML. - Smoking, previous chemotherapy treatment, and exposure to radiation may affect the risk of adult AML. - Signs and symptoms of adult AML include fever, feeling tired, and easy bruising or bleeding. - Tests that examine the blood and bone marrow are used to detect (find) and diagnose adult AML. - Certain factors affect prognosis (chance of recovery) and treatment options. Adult acute myeloid leukemia (AML) is a type of cancer in which the bone marrow makes abnormal myeloblasts (a type of white blood cell), red blood cells, or platelets. Adult acute myeloid leukemia (AML) is a cancer of the blood and bone marrow. This type of cancer usually gets worse quickly if it is not treated. It is the most common type of acute leukemia in adults. AML is also called acute myelogenous leukemia, acute myeloblastic leukemia, acute granulocytic leukemia, and acute nonlymphocytic leukemia. Leukemia may affect red blood cells, white blood cells, and platelets. Normally, the bone marrow makes blood stem cells (immature cells) that become mature blood cells over time. A blood stem cell may become a myeloid stem cell or a lymphoid stem cell. A lymphoid stem cell becomes a white blood cell. A myeloid stem cell becomes one of three types of mature blood cells: - Red blood cells that carry oxygen and other substances to all tissues of the body. - White blood cells that fight infection and disease. - Platelets that form blood clots to stop bleeding. In AML, the myeloid stem cells usually become a type of immature white blood cell called myeloblasts (or myeloid blasts). The myeloblasts in AML are abnormal and do not become healthy white blood cells. Sometimes in AML, too many stem cells become abnormal red blood cells or platelets. These abnormal white blood cells, red blood cells, or platelets are also called leukemia cells or blasts. Leukemia cells can build up in the bone marrow and blood so there is less room for healthy white blood cells, red blood cells, and platelets. When this happens, infection, anemia, or easy bleeding may occur. The leukemia cells can spread outside the blood to other parts of the body, including the central nervous system (brain and spinal cord), skin, and gums. This summary is about adult AML. See the following PDQ summaries for information about other types of leukemia: - Childhood Acute Myeloid Leukemia/Other Myeloid Malignancies Treatment - Chronic Myelogenous Leukemia Treatment - Adult Acute Lymphoblastic Leukemia Treatment - Childhood Acute Lymphoblastic Leukemia Treatment - Chronic Lymphocytic Leukemia Treatment - Hairy Cell Leukemia Treatment There are different subtypes of AML. Most AML subtypes are based on how mature (developed) the cancer cells are at the time of diagnosis and how different they are from normal cells. Acute promyelocytic leukemia (APL) is a subtype of AML that occurs when parts of two genes stick together. APL usually occurs in middle-aged adults. Signs of APL may include both bleeding and forming blood clots.

susceptibility
Who is at risk for Adult Acute Myeloid Leukemia? ?
Smoking, previous chemotherapy treatment, and exposure to radiation may affect the risk of adult AML. Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesnt mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Possible risk factors for AML include the following: - Being male. - Smoking, especially after age 60. - Having had treatment with chemotherapy or radiation therapy in the past. - Having had treatment for childhood acute lymphoblastic leukemia (ALL) in the past. - Being exposed to radiation from an atomic bomb or to the chemical benzene. - Having a history of a blood disorder such as myelodysplastic syndrome.

exams and tests
How to diagnose Adult Acute Myeloid Leukemia ?
Tests that examine the blood and bone marrow are used to detect (find) and diagnose adult AML. The following tests and procedures may be used: - Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken. - Complete blood count (CBC): A procedure in which a sample of blood is drawn and checked for the following: - The number of red blood cells, white blood cells, and platelets. - The amount of hemoglobin (the protein that carries oxygen) in the red blood cells. - The portion of the sample made up of red blood cells. - Peripheral blood smear : A procedure in which a sample of blood is checked for blast cells, the number and kinds of white blood cells, the number of platelets, and changes in the shape of blood cells. - Bone marrow aspiration and biopsy : The removal of bone marrow, blood, and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. A pathologist views the bone marrow, blood, and bone under a microscope to look for signs of cancer. - Cytogenetic analysis : A laboratory test in which the cells in a sample of blood or bone marrow are viewed under a microscope to look for certain changes in the chromosomes. Other tests, such as fluorescence in situ hybridization (FISH), may also be done to look for certain changes in the chromosomes. - Immunophenotyping : A process used to identify cells, based on the types of antigens or markers on the surface of the cell. This process is used to diagnose the subtype of AML by comparing the cancer cells to normal cells of the immune system. For example, a cytochemistry study may test the cells in a sample of tissue using chemicals (dyes) to look for certain changes in the sample. A chemical may cause a color change in one type of leukemia cell but not in another type of leukemia cell. - Reverse transcriptionpolymerase chain reaction test (RTPCR): A laboratory test in which cells in a sample of tissue are studied using chemicals to look for certain changes in the structure or function of genes. This test is used to diagnose certain types of AML including acute promyelocytic leukemia (APL).

outlook
What is the outlook for Adult Acute Myeloid Leukemia ?
Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on: - The age of the patient. - The subtype of AML. - Whether the patient received chemotherapy in the past to treat a different cancer. - Whether there is a history of a blood disorder such as myelodysplastic syndrome. - Whether the cancer has spread to the central nervous system. - Whether the cancer has been treated before or recurred (come back). It is important that acute leukemia be treated right away.

stages
What are the stages of Adult Acute Myeloid Leukemia ?
Key Points - Once adult acute myeloid leukemia (AML) has been diagnosed, tests are done to find out if the cancer has spread to other parts of the body. - There is no standard staging system for adult AML. Once adult acute myeloid leukemia (AML) has been diagnosed, tests are done to find out if the cancer has spread to other parts of the body. The extent or spread of cancer is usually described as stages. In adult acute myeloid leukemia (AML), the subtype of AML and whether the leukemia has spread outside the blood and bone marrow are used instead of the stage to plan treatment. The following tests and procedures may be used to determine if the leukemia has spread: - Lumbar puncture : A procedure used to collect a sample of cerebrospinal fluid (CSF) from the spinal column. This is done by placing a needle between two bones in the spine and into the CSF around the spinal cord and removing a sample of the fluid. The sample of CSF is checked under a microscope for signs that leukemia cells have spread to the brain and spinal cord. This procedure is also called an LP or spinal tap. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of the abdomen, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. There is no standard staging system for adult AML. The disease is described as untreated, in remission, or recurrent. Untreated adult AML In untreated adult AML, the disease is newly diagnosed. It has not been treated except to relieve signs and symptoms such as fever, bleeding, or pain, and the following are true: - The complete blood count is abnormal. - At least 20% of the cells in the bone marrow are blasts (leukemia cells). - There are signs or symptoms of leukemia. Adult AML in remission In adult AML in remission, the disease has been treated and the following are true: - The complete blood count is normal. - Less than 5% of the cells in the bone marrow are blasts (leukemia cells). - There are no signs or symptoms of leukemia in the brain and spinal cord or elsewhere in the body. Recurrent Adult AML Recurrent AML is cancer that has recurred (come back) after it has been treated. The AML may come back in the blood or bone marrow.

treatment
What are the treatments for Adult Acute Myeloid Leukemia ?
Key Points - There are different types of treatment for patients with adult acute myeloid leukemia. - The treatment of adult AML usually has 2 phases. - Four types of standard treatment are used: - Chemotherapy - Radiation therapy - Stem cell transplant - Other drug therapy - New types of treatment are being tested in clinical trials. - Targeted therapy - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for patients with adult acute myeloid leukemia. Different types of treatment are available for patients with adult acute myeloid leukemia (AML). Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment. The treatment of adult AML usually has 2 phases. The 2 treatment phases of adult AML are: - Remission induction therapy: This is the first phase of treatment. The goal is to kill the leukemia cells in the blood and bone marrow. This puts the leukemia into remission. - Post-remission therapy: This is the second phase of treatment. It begins after the leukemia is in remission. The goal of post-remission therapy is to kill any remaining leukemia cells that may not be active but could begin to regrow and cause a relapse. This phase is also called remission continuation therapy. Four types of standard treatment are used: Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid (intrathecal chemotherapy), an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). Intrathecal chemotherapy may be used to treat adult AML that has spread to the brain and spinal cord. Combination chemotherapy is treatment using more than one anticancer drug. The way the chemotherapy is given depends on the subtype of AML being treated and whether leukemia cells have spread to the brain and spinal cord. See Drugs Approved for Acute Myeloid Leukemia for more information. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type of cancer being treated and whether leukemia cells have spread to the brain and spinal cord. External radiation therapy is used to treat adult AML. Stem cell transplant Stem cell transplant is a method of giving chemotherapy and replacing blood -forming cells that are abnormal or destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body's blood cells. Other drug therapy Arsenic trioxide and all-trans retinoic acid (ATRA) are anticancer drugs that kill leukemia cells, stop the leukemia cells from dividing, or help the leukemia cells mature into white blood cells. These drugs are used in the treatment of a subtype of AML called acute promyelocytic leukemia. See Drugs Approved for Acute Myeloid Leukemia for more information. New types of treatment are being tested in clinical trials. This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website. Targeted therapy Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Monoclonal antibody therapy is one type of targeted therapy being studied in the treatment of adult AML. Monoclonal antibody therapy is a cancer treatment that uses antibodies made in the laboratory from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups. Treatment Options for Adult Acute Myeloid Leukemia Untreated Adult Acute Myeloid Leukemia Standard treatment of untreated adult acute myeloid leukemia (AML) during the remission induction phase depends on the subtype of AML and may include the following: - Combination chemotherapy. - High-dose combination chemotherapy. - Low-dose chemotherapy. - Intrathecal chemotherapy. - All-trans retinoic acid (ATRA) plus arsenic trioxide for the treatment of acute promyelocytic leukemia (APL). - ATRA plus combination chemotherapy followed by arsenic trioxide for the treatment of APL.
