Combination of Toripalimab and Neoadjuvant Chemoradiotherapy in Esophageal Cancer

December 22, 2019 updated by: Jianhua Fu

A Phase II Trial of Combination of Toripalimab and Neoadjuvant Chemoradiotherapy in Esophageal Squamous Cell Carcinoma

Neoadjuvant chemoradiotherapy (CRT) followed by surgery has become the standard treatment option for locally advanced esophageal cancer (EC). However, only 20% to 40% of EC patients can achieve pathologic complete response (pCR) after neoadjuvant CRT with favorable prognosis. Immunotherapy targeting the PD-1/PD-L1 checkpoints has demonstrated promising activity in advanced EC. The aim of this study was to evaluate the efficacy and safety of the combination of toripalimab (an anti-PD-1 antibody) combined with neoadjuvant CRT in locally advanced esophageal squamous cell carcinoma (ESCC).
