A Study of Sintilimab Plus Chemoradiation Before Surgery for Esophageal Cancer

A Study of Anti-PD-1 Antibody, Sintilimab Plus Chemoradiation Before Surgery for Esophageal Cancer

The purpose of this study is to test the the efficacy and safety of sintilimab in combination with chemoradiation before surgery for esophageal cancer.
