Purpose

This phase II/III trial studies the usefulness of treatment with nivolumab and ipilimumab in addition to standard of care chemotherapy and radiation therapy in patients with esophageal and gastroesophageal junction adenocarcinoma who are undergoing surgery. Immunotherapy with antibodies, such as nivolumab and ipilimumab, may remove the brake on the body's immune system and may interfere with the ability of tumor cells to grow and spread. Chemotherapy and radiation therapy may reduce the tumor size and the amount of normal tissue that needs to be removed during surgery. A combined treatment with nivolumab and ipilimumab, chemotherapy, and radiation therapy might be more effective in patients with esophageal and gastroesophageal junction adenocarcinoma who are undergoing surgery.
