Study Overview
Brief Summary
China with high incidence of esophageal cancer, the number of new cases and deaths account for about 50% of the world every year. In the past few decades, surgery, radiotherapy, chemotherapy and other treatments were continuously improved, however, the mortality of esophageal squamous cell carcinoma patients was not significantly decreased. For patients with locally advanced esophageal cancer, direct surgery is not effective. It is difficult to achieve radical resection by surgery merely, and even if many patients receive surgery, they may eventually have tumor recurrence and poor survival rate. Therefore, it is necessary to explore effective perioperative neoadjuvant treatment to reduce the risk of postoperative recurrence and improve the postoperative survival rate of patients. According to the reports, the expression of PD-L1 in esophageal cancer was about 41.4%. Therefore, PD-1/ PD-L1 immunocheckpoint inhibitor may become a new method for the treatment of esophageal cancer. Preliminary clinical results showed that immunotherapy combined with chemoradiotherapy provided a synergies antitumor effect. Multiple clinical results showed that serplulimab provided higher overall response rate for advanced esophageal cancer. However, in patients with locally advanced esophageal cancer, the efficacy of serplulimab combined with chemotherapy for sequential radical surgery is still unclear. The purpose of this study is to observe and evaluate the efficacy and safety of silulimab combined with chemotherapy in the neoadjuvant therapy of resectable esophageal squamous cell carcinoma.
