About

The goal of this prospective, open-label, single-center clinical study is to learn about the efficacy and safety of aderbelimab combined with chemotherapy in the perioperative treatment of esophageal and esophagogastric junction cancer. The main question it aims to answer are:prediction for pCR after perioperative adebrelimab and chemotherapy in esophageal and esophagogastric junction carcinoma
