Dr. Luis A. Diaz Jr. of Memorial Sloan Kettering Cancer Center published a paper on a drug trial of 18 adults with rectal cancer. The results were astonishing -- the cancer was wiped out in every one of those patients. "I believe this is the first time this has happened in the history of cancer," he says. Causing complete remission with minimal side effects, the drug called dostarlimab proves promising for the future of cancer research and treatment. However, "very little is known about the duration of time needed to find out whether a clinical complete response to dostarlimab equates to cure," a professor notes.
