Impact of perioperative intraperitoneal chemotherapy on the treatment of primary gastric cancer

Perioperative intraperitoneal chemotherapy provides effective prevention of peritoneal recurrence after resection in advanced gastric cancer, especially in gastric cancer with serosal invasion. With improved local-regional control, improved survival rate for advanced gastric cancer is achieved. This type of regional chemotherapy is an independent treatment-related prognostic factor for advanced gastric cancer. There are several methods of perioperative intraperitoneal chemotherapy. Among them, early postoperative intraperitoneal chemotherapy is simple and easy to perform.
