Overview

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.
