neoadjuvant anti-pd-1 antibody shr-1210 and radiation in resectable esophageal squamous cell carcinoma

Conditions: Esophageal Neoplasms; Esophageal Diseases

Summary: the objective of this study is to evaluate the efficacy and safety of radiation therapy combined with anti-pd-1 antibody shr-1210 followed by surgery in treating patients with resectable esophageal squamous cell carcinoma
