Brief summary
HIPEC-01 is a prospective, open, randomized multicenter phase III clinical study conducted in China. To determine the efficacy of hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of locally advanced gastric cancer, patients are randomized into HIPEC group and control group. In HIPEC group, the patients undergo radical gastrectomy with D2 lymphadenectomy and HIPEC with paclitaxel and postoperative chemotherapy. Patients in the control group just undergo radical gastrectomy with D2 lymphadenectomy followed by postoperative chemotherapy. Patients in both groups receive 6-8 cycles of postoperative systemic chemotherapy (XELOX or SOX regimens) and are followed up for 5 years or until death.
Detailed description
Gastric cancer (GC) is the fourth most common cancer, and the second leading cause of cancer-related death worldwide. Advances in diagnostic and therapeutic approaches have achieved long-term survival for early GC. However, receiving perioperative/postoperative systemic chemotherapy and gastrectomy with D1-D2 lymph node dissection, 5-year survival rates of advanced gastric cancer remain under 30%. 40-60% of recurrences are peritoneal and/or locoregional. hyperthermic intraperitoneal chemotherapy (HIPEC) technique is increasingly used in the curative treatment of primary and digestive peritoneal carcinomatosis, in association with cytoreductive surgery. Theoretically, HIPEC eliminates free cancer cells that can be released into peritoneal cavity during the gastrectomy and prevents peritoneal carcinomatosis recurrences. The benefit of using HIPEC as an adjuvant treatment for advanced gastric cancer has been reported in several randomized studies and a meta-analysis. Surgical resection combined with HIPEC significantly reduces the peritoneal recurrences and improves the overall survival of GC patients. But there is not a prospective and randomized phase III clinical study of HIPEC in the treatment of locally advanced gastric cancer after radical surgery in China so far. In order to evaluate the survival benefit and safety of radical surgery and HIPEC followed by postoperative chemotherapy in local advanced gastric cancer, patients who fulfill the inclusion and exclusion criteria will be recruited in this study and randomized to two treatment groups (HIPEC group and control group). In HIPEC group, the patients undergo radical gastrectomy with D2 lymphadenectomy and HIPEC with paclitaxel and postoperative chemotherapy. Patients in the control group just undergo radical gastrectomy with D2 lymphadenectomy followed by postoperative chemotherapy. Patients in both groups receive 6-8 cycles of postoperative systemic chemotherapy (XELOX or SOX regimens) . Patients are followed up for 5 years and the survival outcome will be analyzed.
Interventions
PROCEDURED2 lymphadenectomy
PROCEDUREHyperthermic Intraperitoneal Chemotherapy
The first HIPEC is conducted within 48 h after surgery: Normal saline 3000 -4000ml, Paclitaxel 75mg/m\^2, 43°C, 60min. The second HIPEC is performed after 24 hours of the first HIPEC. The regimens are Paclitaxel 100 mg/m\^2, 43°C, 60min.
DRUGSystemic chemotherapy (XELOX or SOX regimens)
XELOX regimen: Oxaliplatin: 130 mg/m\^2, IV, d1; Capecitabine: 1 g/m\^2 bid, days 1-14, every 3 weeks for a total of 6-8 cycles. SOX regimen: Oxaliplatin: 130 mg/m\^2, IV, d1; S-1, 40 mg/m\^2 bid, po, day 1-14 (S-1: BSA \<1.25m\^2, 40mg bid, 1.25m\^2≤ BSA ≤1.5m\^2, 50mg bid, BSA\>1.5m\^2, 60 mg bid) bid, d1-14, po, every 3 weeks for a total of 6-8 cycles.
