What this Trial Is About

The FOLFIRINOX regimen has become the standard treatment regimen for advanced colorectal cancer, advanced pancreatic cancer and postoperative adjuvant treatment for pancreatic cancer. With the continuous exploration of Chinese scholars, it has also revised the modified dose suitable for the physical fitness of the Chinese people, which is well tolerated and has a clear efficiency. The drugs in this program are all standard treatment drugs for gastric cancer. In 2020, JAMA Network Open and JAMA Oncology successively reported the application of FOLFIRINOX in the perioperative period of gastric cancer and the late-stage results of gastric cancer, and they obtained very amazing data respectively. According to the results of CheckMate-649, the FDA approved Nivolumab combined chemotherapy for first-line treatment of advanced or metastatic gastric cancer, gastroesophageal junction cancer and esophageal adenocarcinoma, regardless of PD-L1 expression. At the same time, this is also the first first-line immunotherapy approved by the FDA for gastric cancer.However, there is no definite conclusion about the preoperative neoadjuvant or perioperative clinical research, so it is necessary to explore the efficacy of PD-1 antibody in the perioperative period. This study is a single-center, randomized, controlled phase II clinical study. The primary endpoint of the study is the perioperative administration of mFOLFIRINOX regimen combined with PD-1 antibody and D2 radical resection for the treatment of resectable advanced gastric cancer. The deep tumor remission rate (TRG0 and TRG1) , secondary endpoints include pCR rate, 3-year DFS rate, safety, R0 resection rate, D2 radical resection rate, 5-year DFS rate, 5-year OS rate.
