Task: Sentence Composition
Input (English): An early experiment of immunotherapy against melanoma may be too early to allow for a cost estimate. We’ll give the story the benefit of the doubt for reporting: “In six of the 11 patients in the trial, the melanoma stopped progressing for 12 to 19 weeks. Another patient was declared in remission because his cancer ceased to spread and, after several months, disappeared altogether. Three years later, researchers continue to detect the presence of the cloned cells they infused into the patient” The story stated: “Currently, the T cells have limited staying power and often die off before their work is done. Doctors give them a boost by administering a growth factor called interleukin-2. But at high doses, it can cause dangerously low blood pressure, breathing problems, kidney failure and heart arrhythmias. Yee’s group showed that by choosing T cells more selectively, patients can get by with much lower doses of interleukin-2, making the treatment less toxic.” But we’re not told what side effects were observed in the 11 patients in the study. In reality the study originally involved a high dose (3 subjects) and low dose (8 subjects) IL-2 arm. The high dose arm was closed by the Data and Safety Monitoring Board prematurely due to unacceptable toxicity. The early, small, preliminary nature of the study was clear from the story. Steven Rosenberg’s comments at the end also gave perspective. No disease mongering at play here. Several independent sources were quoted. Brief reference was made to one patient having had 6 years of chemotherapy “only to have his melanoma return.” And Rosenberg’s comments at the end note a competing immunotherapy approach. But the story didn’t give readers a clear context of melanoma treatments, or of why and for whom immunotherapy would be tried, etc. We think it’s clear from the story that this is only an experimental approach right now. The relative novelty of this approach for melanoma was evident in the story. It’s clear that the story did not rely solely on a news release.
Output (English): Researchers report progress in cancer immunotherapy
