Abstract
Peritoneal metastasis is one of the most frequent types of metastasis associated with poor prognosis in cases of gastric cancer. One new method for treating the disease, known as hyperthermic intraperitoneal chemotherapy (HIPEC), involves local delivery of heat-activated chemotherapy drugs in order to target free circulating tumor cells and micrometastatic lesions. The purpose of this minireview paper is to describe recent developments in the field of HIPEC as a means of preventing and managing peritoneal dissemination in patients with gastric cancer. Studies conducted have shown the effectiveness of HIPEC in decreasing the risk of peritoneal recurrences and improving the prognosis of survival. Although certain difficulties remain in terms of surgical and postoperative complications, efforts to improve the effectiveness of the treatment are underway.
Core Tip: Hyperthermic intraperitoneal chemotherapy relies on a synergic use of heat and chemotherapy to prevent and manage the metastatic disease of the stomach. Hyperthermic intraperitoneal chemotherapy can improve patient outcomes in terms of prevention of peritoneal metastases and survival, especially when used along with cytoreductive surgery. While complications may arise during the perioperative period, such issues can be managed in dedicated settings.
