Abstract

PURPOSE
We performed retrospective study to evaluate the preventive effect of intraperitoneal cisplatin installation (IPCI) on peritoneal recurrence after curative resection of advanced gastric cancer.
MATERIALS AND METHODS
The effect of IPCI was evaluated in 297 advanced gastric carcinoma patients from January 1993 to December 1996. In IPCI group, 100 mg/body of cisplatin in one liter of saline was installed in peritoneal cavity before wound closure in operating room and drained out 2 hours later. Postoperative adjuvant chemotherapy with combination of 5-FU and cisplain was performed. 155 cases were treated by IPCI. Median follow-up period was 26 months.
RESULTS
Out of 139 (46.8%) recurred cases, peritoneal, local and distant recurrences developed in 65 (37.8%) cases, 66 (38.4%) cases and 41 (23.8%) cases respectively. In univariated analysis for survival and recurrence, IPCI, T stage and N stage were significant prognostic factors. As regards to peritoneal recurrence, IPCI and T stage were significant factors. In multivariated survival analysis, as regards to recurrence, IPCI, T stage and N stage were significant prognostic factors. As regards to peritoneal recurrence, IPCI was the only significant independent prognostic factor.
CONCLUSION
We concluded that IPCI can effectively prevent peritoneal recurrence and overall recurrence and it shows marginal survival benefit in advanced gastric cancer patients with serosa invasion.
