A small rectal cancer clinical trial has had an unexpected result — remission in every patient.
According to a story by Gina Kolata in recent editions of The New York Times, the cancer vanished in each of the 18 patients, "undetectable by physical exam, endoscopy, PET scans or MRI scans."

That view is confirmed by Dr. Alan P. Venice, a colorectal cancer specialist at the University of California, San Francisco, was wasn't involved in the study. That kind of record, he says, is "unheard of."
The patients entered the study with the expectation that they might face chemotherapy, radiation and, most likely surgery that cold result in bowel, urinary and sexual dysfunction — and require colostomy bags. All 18 were pleasantly surprised to find that no such treatments were necessary.

The immunotherapy drug the patients were given every three weeks for six months — dostarlimab, a checkpoint inhibitor produced by GlaxoSmithKline, which sponsored the clinical trial — costs about $11,000 per dose. "It unmasks cancer cells, allowing the immune system to identify and destroy them," the story says.
The study's authors indicate that although the earliest patient to complete the trial is more than two years post-treatment, many have only been involved for six months, and all patients will be monitored for at least five years.

The Post story quotes Dr. Julie Gralow, chief medical officer and executive vice president of the American Society of Clinical Oncology, as commenting that "I'm excited when you see such a dramatic response. It gives me hope we can find such a dramatic [treatment] for other cancers, too."
