Radiation boost may improve immunotherapy for esophageal cancer
NCT ID NCT05978193
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding low-dose or standard radiotherapy to the usual combination of immunotherapy (anti-PD-1) and chemotherapy can help people with metastatic esophageal squamous cell carcinoma. About 100 adults who have not had prior treatment will participate. The goal is to see if the radiation helps control the cancer longer without causing too many side effects.
