Chemoradiotherapy, Esophagus Cancer, Immunotherapy, Oligometastatic Disease
Conditions
Brief summary
Chemoradiotherapy(CRT) is the main treatment for esophageal cancer patients with recurrent desease,and checkpoint blockade (PD-1) have been shown to be effective in advanced esophageal cancer. Therefore, PD-1 combined with chemoradiotherapy (CRT)may further improve the efficacy and become a new method for the treatment of esophageal cancer.This study intends to conduct a single-arm, prospective clinical study, aiming to evaluate the safety and efficacy of PD-1 combined with chemoradiotherapy(CRT) in patients with oligometastatic esophageal squamous cell carcinoma.
