A randomized phase III trial exploring the prognostic value of extensive intraoperative peritoneal lavage in addition to standard treatment for resectable advanced gastric cancer: CCOG 1102 study.

A randomized controlled trial has started in Japan to evaluate the efficacy of extensive intraoperative peritoneal lavage in the treatment of resectable advanced gastric cancer. Patients with T3 or deeper carcinoma of the stomach are intraoperatively randomized to either extensive intraoperative peritoneal lavage + arm or extensive intraoperative peritoneal lavage- arm. A total of 300 patients will be accrued from 20 institutions. The primary endpoint is disease-free survival, and secondary end-points are overall survival, peritoneal recurrence-free survival and incidence of adverse events.
