[Key measures to improve the efficacy of diagnosis and treatment of gastric cancer with peritoneal metastasis].

Once peritoneal metastasis occurs, the prognosis of gastric cancer is extremely poor, and the median survival time is only about 6-9 months. In recent years, the clinical research on peritoneal metastasis of gastric cancer has become a hot spot. Based on the research results at home and abroad, the author put forward several important measures, which will contribute to further improve the curative effect of gastric cancer with peritoneal metastasis. (1) Improving the preoperative diagnostic rate of peritoneal metastasis is a prerequisite factor; (2) actively preventing peritoneal metastasis is the priority strategy; (3) combining systemic and intraperitoneal therapy is the key mode. (4) performing radical conversion surgery is the fundamental means. In this paper, the above important issues are discussed to communicate with colleagues.
