Efficacy and Safety of Serplulimab Combined With Etoposide and Cisplatin as Neoadjuvant Therapy in Limited-Stage Small-Cell Carcinoma of the Esophageal

Summary

This study is a prospective, single-center, single-arm phase II clinical trial designed to evaluate the efficacy and safety of serplulimab in combination with etoposide and platinum-based chemotherapy as neoadjuvant treatment for patients with limited-stage small cell carcinoma of the esophagus (SCCE). The primary endpoint is the pathological complete response (pCR) rate. Secondary endpoints include major pathological response (MPR) rate, objective response rate (ORR), disease control rate (DCR), disease-free survival (DFS), overall survival (OS) and safety. A total of 15 patients are expected to be enrolled.
