About

The purpose of this study was to evaluate the safety, feasibility and outcome of anti-PD-1 antibody (Tislelizumab, BeiGene) combined with neoadjuvant chemoradiotherapy versus neoadjuvant chemoradiotherapy followed by minimally invasive esophagectomy for locally advanced resectable esophageal squamous cell carcinoma (cII-III Stage) patient.

Full description

It is a prospective randomized phase II&III clinical trial sponsored by Shanghai Zhongshan Hospital with other twelve hospitals in China participating in. 476 patients with locally advanced resectable esophageal squamous cell carcinoma (cII-III Stage) are recruited and randomly assigned into the neoadjuvant chemoradiotherapy combined with immunotherapy group (nCRT plus anti-PD-1 Group) and the neoadjuvant chemoradiotherapy group (nCRT Group) according to the proportion of 1:1. The safety, efficacy of protocols and prognosis of patients are compared between the two regimens.

Enrollment: 176 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
