LBA3 Safety and efficacy of pembrolizumab combined with paclitaxel and cisplatin as a neoadjuvant treatment for locally advanced resectable (stage III) esophageal squamous cell carcinoma (Keystone-001): Interim analysis of a prospective, single-arm, single-center, phase II trial

Abstract

Neoadjuvant concurrent chemoradiotherapy with surgery is the standard treatment for esophageal squamous cell carcinoma (ESCC) in NCCN guidelines. But many patients refused or abandon radiotherapy because of the intolerable adverse effects. We designed a single-arm, open-label, phase II trial of pembrolizumab plus paclitaxel, cisplatin followed by Da Vinci robot surgery for locally advanced (stage III) ESCC. The purpose is to observe and evaluate the efficacy and safety.
