Brief Summary

The purpose of this study is to investigate the efficacy and safety of neoadjuvant treatment of locally advanced esophageal squamous carcinoma with a PD-1/CTLA-4 bispecific antibody (Cadonilimab) in combination with platinum-containing chemotherapy (Paclitaxel Polymeric Micelles for Injection combined with Cisplatin). Includes pathologic complete remission rates (pCR rates) after 2-4 cycles of Cadonilimab combination chemotherapy. The objective remission rate (ORR), major pathologic remission rate (MPR), R0 resection rate and 2-year overall survival (OS) and progression-free survival (OS) rates, and safety of neoadjuvant treatment of locally advanced esophageal squamous carcinoma with Cadonilimab combined with chemotherapy.
