This defect in mismatch repair is an autosomal dominant disorder that increases risk for several types of cancer, including colorectal, uterine, gastric, pancreatic, ovarian, and bile duct.Objective: To show that a single immunotherapeutic agent can successfully treat more than 1 type of cancer in the same patient when the cancer has a common genetic cause.Case Report: We evaluated a 55-year-old woman with extensive gastrointestinal cancer. The patient had a family history of ...References1. Lee V, Murphy A, Le DT, Diaz LA. Mismatch repair deficiency and response to immune checkpoint blockade. Oncologist. 2016;21:1200-11.
