A Study of Perioperative Camrelizumab Combined With Chemotherapy in Patients With Resectable ESCC

The incidence of esophageal cancer is ranked seventh in the world, and the mortality rate ranks sixth in the world. Surgical treatment of early esophageal cancer has a good prognosis, and advanced esophageal cancer often requires a combination of surgery, chemotherapy, radiotherapy and immunotherapy, but the prognosis is still poor. The investigators designed a randomized, controlled, phase II study of perioperative camrelizumab combined with albumin paclitaxel and cisplatin in patients with resectable esophageal squamous cell carcinoma. The purpose of this study is to observe and evaluate the efficacy and safety of camrelizumab combined with albumin paclitaxel and cisplatin as perioperative treatment of advanced esophageal squamous cell.
