Task: Sentence Composition
Input (English): While no price has been set, this story still confronts cost by pointing out that other biotech drugs cost thousands of dollars per month of treatment. The story included key details about the difference in survival rates and length between the treatment and control arms of the trial. The story gives both the median survival length and the three-year survival figures for participants in the treatment and placebo arms of the trial. It might have been helpful to say "half the men survived at least" rather than "median survival was." The story lists the serious side effects reported in the trial and the fact that earlier trials raised worries about strokes related to treatment. Although this story, like the USA Today report that we reviewed, stated in the lead that patients receiving Provenge lived four months longer without specifying that it was four months longer than placebo, not standard therapy, it does a better job of detailing the available results. The story improperly compares the reported survival advantage of the experimental treatment to the expected survival of men receiving standard chemotherapy, implying the two treatments have been tested head-to-head. The story also includes speculation that Provenge could be more effective when given earlier in the course of the disease, even though there is no evidence to support the statement. Quotes at the end of the story from leaders of some patient advocacy groups overstated the evidence of effectiveness, but they seem to accurately reflect the perspective of these activists. The story didn’t discuss the condition of advanced prostate cancer in detail, so this is N/A. The story includes comments from independent experts. It notes that the drug developer paid for the study and that the lead researcher owns company stock. In addition, the story notes how the company stock price was fluctuating; a good reminder that research reports can have substantial financial consequences. The story did not refer to the stock price jump earlier this month that followed the vague company announcement at a meeting with analysts claiming that the treatment extended patient survival. The story mentions that chemotherapy with Taxotere is the only approved treatment for patients with advanced prostate cancer. It should not have stated that Provenge produces a greater survival benefit, since the treatments have not been directly compared. The story points out that Provenge has not been approved by the FDA. The story reported that Provenge is the first therapeutic cancer vaccine "to meet a preset goal for improving survival in late-stage testing." The story included original reporting. However, one comment from a spokesman for the American Urological Association appears to have been taken from a news release without specifying that it was contained in a statement, rather than in an interview.
Output (English): Study: Prostate cancer vaccine extends survival
