Abstract:Objective：To discuss the effect of intra-operative and post-operative hyperthermic intraperitoneal lavage chemotherapy for Ⅲb and IV gastric cancer on post-operative peritoneal metastasis and survival rate.
Methods ：The clinical data of 31 cases of gastric cancer (control group) who underwent operation only and 50 cases (chemotherapy group) who receved operation combined with intra-operative and post-operative hyperthermic intra-peritoneal lavage chemotherapy were comparatively studied.
Results：The survival rate of control group after 2 years and 3 years was lower than that of the chemotherapy group, and the intraperitoneal recurrence rate of control group after 2 years and 3 years was higher than that of chemotherapy group.
Conclusions： Intra-operative and post-operative hyperthermic intraperitoneal lavage chemotherapy for gastric cancer has important significance in prevention and treatment of peritoneal metastasis and can improve survival rate.
