[Clinical result of intraperitoneal hyperthermic chemoperfusion for gastric cancer with serosal invasion to prevent peritoneal recurrence].
In order to evaluate clinical effects of intraperitoneal hyperthermic chemoperfusion (IHCP) to prevent peritoneal recurrence in gastric cancer patients with serosal invasion, the clinical outcome was studied in 126 gastric cancer patients with macroscopic serosal invasion. Results of 59 patients who had surgery combined with IHCP (IHCP group) were compared with those of 67 patients who had surgery alone (control group). IHCP was performed for 120 minutes just after surgery under hypothermic general anesthesia with perfusate containing 10 micrograms/ml of mitomycin C. The inflow temperature and the outflow temperature of the perfusate were controlled to be 44.5 approximately 45 degrees C, and 43 approximately 44 degrees C, respectively. The 2-, 4- and 8-year survival rates for the IHCP group were 86%, 74% and 66%, respectively, against 78%, 59% and 50%, respectively, in the control group. The survival rates of the IHCP group were significantly better than those of the control group. Peritoneal recurrences after surgery were encountered in one of 59 patients in the IHCP group and 17 of 67 patients in the control group. The peritoneal recurrence rate of the IHCP group was significantly lower than that of the control group. These results suggest that IHCP treatment is effective in prevention of peritoneal recurrences after surgery for gastric cancer patients with serosal invasion.
