Task: Sentence Composition
Input (English): There’s no mention of how much this might cost, but we’ll rate this N/A since the story makes it clear that this is early research. The story did a good job of reporting the scope of the observed benefit, stating that 21% of patients “experienced a prolonged survival” and then breaking down that number with more specifics. For example, it reported that after three years, 21% the treated patients survived versus 4% of a historical control group. But in a small study, why not cite the actual numbers – how many out of how many? – rather than make readers do the math in their heads. The story reported “substantial risks” with the treatment, including “dangerous swelling in the brain that can lead to seizures and other complications.” It reported that one patient had a life-threatening blood clot in the brain that required surgery. The story did not explain how many of the patients in the trial experienced the substantial risks. This was something NBC News handled better (see the review). We can look the other way on the benefits criterion, but the story should have given some estimate of how many people experienced harm from the treatment. We applaud cautious framing in both the story and the headline. The lead refrained from overstating the evidence, saying the treatment “may help some patients.” That conservative tone continued in the second paragraph, which said it “seems to have extended survival in a small group of patients.” The story admonished that the research is “at a very early stage” and “much more follow-up” is needed, and also explained that the study’s use of a historical control group of patients “could produce misleading conclusions.” No disease-mongering here. The story said glioblastoma is the “most common and aggressive malignant brain tumor in adults.” The story did have an independent source, but did not mention that seven of the researchers on the study reported financial interests in the company that holds the license for the treatment. The story mentioned standard treatment without getting specifics, and also mentioned plans to combine this treatment with chemotherapy and other drugs. It could have also mentioned other studies that are attempting to find a cure for glioblastoma. The story made clear this is an experimental therapy and thus not yet widely available. The story made it sound like this was a new concept, but this research has been dancing in and out of the sensational spotlight for years. The story drew from a Duke news release but refrained from adopting the news release’s assertion that the poliovirus “significantly improved long-term survival for patients with recurrent glioblastoma.”
Output (English): Doctors Try Genetically Modified Poliovirus As Experimental Brain Cancer Treatment
