Neoadjuvant Immunotherapy Combined With Chemotherapy Sequenced With Endoscopic Resection for Esophageal Cancer (Endosurgery-02)

Summary

This single-center, prospective, single-arm study will evaluate whether giving neoadjuvant chemoimmunotherapy can safely shrink esophageal cancer and allow organ-preserving endoscopic removal in selected patients. Adults with esophageal cancer will receive at least two 3-week cycles of a PD-1 inhibitor (tislelizumab 200 mg on Day 1) plus carboplatin (AUC 3-5, Day 1) and nab-paclitaxel (≤260 mg/m², Day 1). During treatment, routine safety tests are performed. About 3-4 weeks after completing at least two cycles, participants undergo clinical reassessment with examinations and imaging (such as endoscopy, endoscopic ultrasound, PET/CT or CT of the neck, chest, and upper abdomen) to evaluate tumor shrinkage and possible spread. Tumor response is assessed using RECIST 1.1. If a clinical complete response is achieved without obvious nodal disease, endoscopic resection may be performed to preserve the esophagus; otherwise, patients may proceed to surgery or concurrent chemoradiation per clinical judgment. The study focuses on feasibility and safety of this organ-preserving approach and describes tumor responses after therapy. Potential benefits include tumor shrinkage and avoiding major surgery in selected cases; risks include side effects of standard chemotherapy/immunotherapy and procedure-related discomforts from biopsies or endoscopic treatments.
