HIPEC-AS01 is an open, prospective, single-center phase II clinical study, which will include Patients With cT4aNxM0, P0, or cTxNxM1*, P1 Adenocarcinoma of the Stomach or Esophagogastric Junction, to evaluate the efficacy and safety of systemic chemotherapy with HIPEC combined with AS in the perioperative period.~Patients enrolled will be divided into three groups. Among them, group A is the patients with locally resectable GC; group B is patients with peritoneal metastasis stage P1a or P1b, group C is patients with peritoneal metastasis stage P1c.~Intervention:~Group A: 1 cycle HIPEC+S-1 chemotherapy, sequential 3 cycles of chemotherapy (AS plan, Q21d × 3), surgery+HIPEC, sequential 3 cycles of chemotherapy ( AS plan, Q21d × 3).~Group B: 1 cycle HIPEC+S-1 chemotherapy, sequential 3 cycles of chemotherapy (AS plan, Q21d × 3), surgery+HIPEC, sequential 3 cycles of chemotherapy ( AS plan, Q21d × 3).~Group C: 1 cycle HIPEC+S-1 chemotherapy, sequential 3 cycles of chemotherapy (AS plan, Q21d × 3), HIPEC+S-1 chemotherapy, sequential 3 cycles of chemotherapy ( AS plan, Q21d × 3).~In this study, the patient's overall survival was the main evaluation index. It is estimated that the case recruitment will be completed in 2 years, and the follow-up time will be 3 years. The total sample size is approximately 157 cases.

Patients enrolled will be divided into three groups. Among them, group A is the patients with locally resectable GC; group B is patients with peritoneal metastasis stage P1a or P1b, group C is patients with peritoneal metastasis stage P1c. The primary purpose is to evaluate the 3-year overall survival rate.
