Study of PD-1 Antibody Combined With Chemoradiotherapy in Oligometastatic Esophageal Cancer

Phase 2
Conditions
Immunotherapy
Esophagus Cancer
Chemoradiotherapy
Oligometastatic Disease
Interventions
Drug: PD-1 antibody
Radiation: Chemoradiation
Registration Number
NCT04821765
Lead Sponsor
Chinese Academy of Medical Sciences
Brief Summary

Chemoradiotherapy(CRT) is the main treatment for esophageal cancer patients with recurrent desease,and checkpoint blockade (PD-1) have been shown to be effective in advanced esophageal cancer. Therefore, PD-1 combined with chemoradiotherapy (CRT)may further improve the efficacy and become a new method for the treatment of esophageal cancer.This study intends to conduct a single-arm, prospective clinical study, aiming to evaluate the safety and efficacy of PD-1 combined with chemoradiotherapy(CRT) in patients with oligometastatic esophageal squamous cell carcinoma.

Chemoradiotherapy Combined With PD-1 AntibodyAlbumin-Bound PaclitaxelThe arm received chemoradiotherapy, 50-60Gy (BED) was given (1.8-2 Gy or 3-4Gy once daily , 5 days a week) to recurrent sites combined with chemotherapy(Cisplatin 75 mg/m2/day 1, and albumin paclitaxel 150 mg/m2/day 1 , every 3 weeks, 2 cycles ).PD-1 antibody (Tislelizumab) was performed simultaneously with concurrent chemoradiotherapy (Triprizumab 200mg,d1,every 3 weeks,2 cycles). After completion of chemoradiotherapy, PD-1 antibody was given continuously with 2-4 cycles of chemotherapy (the same regimen with concurrent chemotherapy) until 1 year or desease progression.
