Task: Sentence Composition
Input (English): Costs of the MRIdian on-table adaptive radiotherapy in comparison to conventional radiotherapy are not discussed. Given that it is new and more personalized than current treatment options it’s likely to be correspondingly more expensive. Certainly, more frequent MRIs would be very costly. The release provides exact information about increased survival rates in the cohorts of individuals treated with the adaptive versus the convention radiotherapy techniques. “The cohort receiving a higher dose demonstrated a near doubling of median overall survival (Kaplan-Meier estimated median overall survival of 27.8 months compared to 14.8 months).” The news release provides specific results regarding experiences of both groups with regard to toxicity from radiotherapy. We appreciate that the headline of this release starts with the words “early data” because this report deals with preliminary and retrospective research. It was not a clinical trial. Instead, results are based on retrospectively comparing treatment of two groups of patients at four institutions. Respective comparisons can’t account for a host of factors that might influence results. At the end of the news  release readers are told that on the basis of these promising results a clinical trial is being planned. With five-year survival rates of 1 to 14%, it would be hard to engage in disease mongering about pancreatic cancer. This research was sponsored by ViewRay, the company that developed the MRIdian system, and the release does a good job calling attention to this. However, according to the published study, at least one of the co-authors received honoraria from ViewRay Medical Systems. Since this was not included in the release we’re rating this criteria Not Satisfactory. This study was all about comparing alternatives, so it scores Satisfactory on that criterion. It would have helped readers if alternatives would have been described more in laymen’s terms. The news release notes that the next step is a prospective clinical trial and that tells savvy readers that this treatment strategy has a long road of testing ahead. Still, we think the release could have done a better job clarifying that this therapy is not yet ready for patients, outside of the clinical trial. A study that suggests a doubling of median survival is sure to capture the attention of patients newly diagnosed with pancreatic cancer. These patients and their families are closely aware of the glum statistics for the disease. This is a practical concern that the release should have touched on. This technology is indeed novel and unique to ViewRay, though it is becoming available in more and more cancer treatment centers. No unjustifiable language was identified in the news release.
Output (English): Early data shows nearly 2x prolonged median survival for inoperable pancreatic cancer
