Clinical Trial Summary

The purpose of study is to investigate the safety and efficacy of sequential immunotherapy with neoadjuvant chemoradiotherapy for esophageal cancer

Description:

This is a single-arm, phase Ib study. Eligibility criteria include histologically confirmed ESCC and clinical T3-4aN0M0 or T2-4aN+M0 (AJCC/UICC 8). Patients received neoadjuvant radiotherapy (41.4Gy in 23 fractions) with concurrent chemotherapy (paclitaxel, 50 mg/m2, carboplatin area under the curve of 2mg/mL/min, QW*5). Then followed by two cycles of tislelizumab (200mg, Q3W). The primary endpoint was the pathological complete response (pCR) rate and safety.
