A small clinical trial with 12 rectal cancer patients found remission in 100% of them, according to a new paper published in The New England Journal of Medicine.
All the patients took
dostarlimab, a monoclonal antibody, every 3 weeks for 6 months. During follow-up, the cancer had disappeared on MRI scans, PET scans, biopsies, endoscopic tests, and physical exams.
“I believe this is the first time this has happened in the history of cancer,” Luis Diaz Jr., MD, the senior study author and an oncologist at Memorial Sloan Kettering Cancer Center in New York City, told The New York Times.
