Prophylactic Preoperative HIPEC in Advanced Gastric Cancer at High Risk of Peritoneal Recurrence

Overview

The study was designed to evaluate the efficacy of perioperative FLOT chemotherapy in combination with perioperative hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with advanced gastric cancer at high risk of peritoneal metastases. The impact of treatment on peritoneal recurrence and survival over 6 months, 1, 3 and 5 years will be assessed.

This is a randomized, multicenter, clinical trial in which 598 patients with advanced gastric cancer at high risk of peritoneal metastases are randomly allocated to receive either preoperative hyperthermic intraperitoneal chemotherapy (HIPEC) plus gastrectomy (experimental group) or gastrectomy alone (control group). All patients, regardless of allocation, will additionally receive 4 cycles of FLOT chemotherapy (docetaxel 50 mg/m2, oxaliplatin 85 mg/m2, leucovorin 200 mg/m2 and 5-fluorouracil 2600 mg/m2) before surgery ± HIPEC and 4 cycles of FLOT chemotherapy after gastrectomy. The main outcome is frequency of peritoneal recurrence by 6-months post-operative. Patients will be followed for 5 years and undergo additional evaluations at 6 months, 1 year, 3 and 5 years. The study will take place at 7 hospitals across Poland. All participating centers have the equipment and skills to perform all necessary procedures in this study. The below centers specialize in the treatment of stomach cancer with many documented years of experience. They are trained in the maintenance of a register, possess the skills to conduct appropriate research analyses and are equipped with a system for assessing the quality of both surgical and oncological treatment.
