This is a multicenter, open-label, randomized, controlled clinical study to compare the efficacy and safety of cardonilizumab combined with neoadjuvant chemotherapy and surgery versus neoadjuvant chemoradiotherapy and surgery in locally advanced ESCC. Subjects were randomly divided into experimental group and control group, the experimental group received neoadjuvant immunotherapy concurrent chemotherapy regimen, the control group received neoadjuvant concurrent chemoradiotherapy regimen, and then received McKeown surgery. The primary outcome measures were complete pathological response (pCR), and the secondary outcome measures were major pathological response (MPR), EFS (event-free survival), OS (overall survival), overall response rate (ORR), decreased pathological stage, R0 resection rate, adverse events (AE), and perioperative complications
