Review Multicenter StudyImmune Checkpoint Inhibitors in Locally Advanced, Unresectable, and Metastatic Upper Gastrointestinal Malignancies.
Upper gastrointestinal (UGI) malignancies including esophageal, gastroesophageal junction (GEJ), and gastric cancers have a poor prognosis in the metastatic setting. Treatment with cytotoxic chemotherapy remains the treatment of choice in the first-line setting with the addition of trastuzumab, a monoclonal antibody against HER-2, if the tumor is HER2-positive. Before the era of checkpoint inhibitors, there were only few treatment options after failure of the first-line systemic therapy. ⋯ Based on recent and ongoing studies, eligible patients who have progressed beyond the first-line cytotoxic chemotherapy may benefit from immunotherapy. This review outlines the checkpoint inhibitors that are currently or previously being investigated for patients with metastatic UGI cancers.
