text_1: Provenge vaccine prolongs life in prostate cancer patients
text_2: "This story provides many of the key details readers need to understand the results of the trial of Provenge – being evaluated as a treatment for advanced prostate cancer – but the overall tone of the story emphasizes the good news while soft-peddling the caveats. Even though the story points out that only a third of men receiving the experimental approach were alive three years after they entered the trial, it would be understandable if readers concluded that Provenge is a dramatic advance in prostate cancer treatment and offers substantial advantages, with no disadavantages, compared to the chemotherapy typically offered similar patients. This USA Today story was about half the length of the AP report we also reviewed. Important facts were omitted that undercut the usefulness of the story; for example, the failure to note that the lead researcher owns stock in the company developing the drug or that the FDA declined to approve this drug two years ago because of concerns about potential side effects and questions about its actual effectiveness. While some cancer experts quoted elsewhere termed the trial findings an ""incremental"" advance, all of the comments included in this story portrayed the results as a dramatic advance. The story did not explain that the results have not been peer-reviewed and that independent experts have yet to see the raw data."
