【 摘 要 】

Objective To investigate the efficacy and safety of a novel method of hyperthermic intraperitoneal chemotherapy (HIPEC) as adjuvant therapy for stage-III gastric cancer. Methods Patients with stage-III gastric cancer who underwent D2 radical gastrectomy were randomly assigned to the HIPEC or control group four weeks after surgery. The HIPEC group was treated with cisplatin (60 mg/m2) administered with a HIPEC device on days 1 and 3 (30 mg/m2 each time), along with oral S-1, 40–60 mg, twice daily, for 14 days. The control group was treated with cisplatin (60 mg/m2) administered intravenously plus oral S-1 (40–60 mg, 2/d for 14 days). The primary outcome of the study was disease-free survival (DFS). Results Total 114 patients were included in the study, with 57 patients in each group. The median DFS was 29.0 months in the HIPEC group, which was significantly longer than that in the control group (15.0 months, p = 0.006). The two-year DFS rate in the HIPEC group was higher than that in the control group (50.4% vs. 25.5%). Median OS was 42.0 month in the HIPEC group and 31.0 month in the control (p = 0.042). Peritoneal metastasis occurred in six patients in the HIPEC group (10.5%) and 12 patients in the control (21.1%, p = 0.198). No significant difference in the incidence of adverse event except for thrombocytopenia. Conclusion HIPEC with cisplatin plus oral S-1 is a safe and effective adjuvant therapy for patients with advanced gastric cancer following D2 radical gastrectomy. Trial registration: This study was registered at ClinicalTrials.gov with the identifier (NCT number): NCT02396498
