Checkpoint Blockade for Melanoma

Case 1: BRAF Wild-type Melanoma A 42-year-old woman is found to have melanoma metastatic to lung and subcutaneous sites Her melanoma does not have a BRAF mutation She has a KPS of 80% She is overweight and has type II diabetes controlled with metformin No other significant medical history
