Summary

For peritoneal metastatic gastric/gastroesophageal junction adenocarcinoma (cT3-4NanyM1), PD-1 antibody combined with chemotherapy and hyperthermic intraperitoneal chemotherapy (HIPEC) can downstage tumor stage, increase the conversion resection rate, and may improve the long-term survival. Tislelizumab, an anti-PD-1 antibody, has recently been proved in the first- and second-line standard treatment for advanced or metastatic gastric or gastro-oesophageal junction adenocarcinoma.In the subgroup analysis of RATIONALE-305 trial, tislelizumab also showed good efficacy in gastric/gastroesophageal junction adenocarcinoma patients with peritoneal metastasis. Combination of tirellizumab,SOX and HIPEC for peritoneal metastatic gastric/gastroesophageal junction adenocarcinoma could be a novel therapeutic strategy to increase response rate and therapeutic efficacy. This study is a monocenter, single-arm phase 2 clinical trial to evaluate tolerability, safety and efficacy of perioperative tirellizumab in combination with SOX and HIPEC in peritoneal metastatic gastric/gastroesophageal junction adenocarcinoma.
