Desmoplastic melanoma responds to PD-1 blockade immunotherapy

Tumors from desmoplastic melanoma, a rare cancer most commonly found on the head or neck, can often be shrunk significantly before surgery by an immunotherapy known as PD-1 blockade, a result that may reduce the need for disfiguring surgery and radiation. These are the findings of a small clinical trial in this disease by researchers from SWOG Cancer Research Network, a cancer clinical trials group funded by the National Cancer Institute (NCI).
