Spots Global Cancer Trial Database for Extensive Intraoperative Peritoneal Lavage After Curative Gastrectomy for Locally Advanced Gastric Cancer (SEIPLUS)

Study Description

Brief Summary: The investigators study aims to explore the potential function of extensive intraoperative peritoneal lavage in improving the overall survival and progression-free survival for locally advanced gastric cancer after curative resection. Hypothesis: Overall survival and progression-free survival of locally advanced gastric cancer are improved by extensive intraoperative peritoneal lavage.

Detailed Description: Gastric cancer has been one of the most frequently common cancers and remains the third leading cause of death among malignant tumors all over the world. Surgery has always been considered as the most effective treatment. While significant surgical technique and perioperative management have dramatically improved the survival of patients with advanced gastric cancer, patients with T4 stage or serosal-positive gastric cancer often suffer from recurrence as peritoneal dissemination, and the prognosis of those patients is extremely poor. Despite curatively resected, Peritoneal metastasis is completed by the implantation of peritoneal free cancer cells exfoliated from serosa-invasive tumors. Therefore, things need to be done to eliminate the free exfoliated cancer cells on the peritoneal lining in order to reduce the risk of peritoneal recurrence. A multi-institutional prospective, randomized trial has been launched by Kuramoto recently. The trail was intended to demonstrate the superiority in overall survival of addition of Extensive Intraoperative peritoneal Lavage (EIPL) to standard treatment in patients with≥T3 carcinoma of stomach. Based on the'limiting dilution theory', after total or distal gastrectomy with D2 lymphadenectomy, the peritoneal cavity is extensively rinsed 10 times with 1 L physiological saline at a time, followed by complete aspiration of the fluid. In total, 10 L saline is to be used. In this study, the EIPL-IPC group had a significantly lower incidence of peritoneal recurrence. Furthermore, the 5-year overall survival rate of the patients in the EIPL-IPC group (43.8%) was significantly better than that of the intraperitoneal chemotherapy (IPC) group (4.6%) and the surgery-alone group (0%). All in all, EIPL is easy to carry out, safe and inexpensive. Therefore, gastrectomy with EIPL will be a new standard treatment of gastric cancer. To ensure the quality of the study, two interim analyses will be planned at the half and the completion of the study respectively. The Data and Safety Monitoring Committee will independently review the interim analysis and stop the study ahead of schedule if necessary. Furthermore, to improve the study progress and quality, the in-house interim monitoring will be performed.
