Adebrelimab Combined With Nab-paclitaxel, Oxaliplatin and Tegafur (AOS) for Perioperative Treatment of Locally Advanced Resectable GC/GEJ

Summary

This study is a single-arm, prospective, phase II clinical trial. The patients are diagnosed with resectable locally advanced (cT3-4N+M0) gastric adenocarcinoma and esophageal gastric adenocarcinoma that had not been treated before. After signing the informed consent form, patients will be screened for the study treatment of Adebrelimab combined with AOS. After 2 cycles of treatment, MDT assessments before surgery will be carried out. Patients with no disease progression will receive one more cycle of treatment before surgery. For patients who have undergone radical surgery, they will continue to receive 3 cycles of the immunochemotherapy after the operation (a total of 6 cycles of combined treatment before and after surgery), followed by Adebrelimab single treatment for up to a year (16 cycles). Patients whose disease progressed that can not be surgically removed after preoperative treatment will be treated by the oncology physicians according to clinical routines.
