[Intraperitoneal administration of cis-platin with arterial infusion chemotherapy of advanced and recurrent gastric cancer].

Arterial infusion therapy was used for 97 patients with AMF therapy. Forty were unresectable, 30 non-curatively resected and 22 recurrent gastric cancers. 5-fluorouracil (5-FU) was administered by arterial continuous infusion, adriamycin (ADM) and mitomycin C (MMC) by bolus infusion in the hospital, and continuous arterial 5-FU infusion and ADM low dose intermittent bolus infusion chemotherapy (AF therapy) was used for outpatients. The clinical effectiveness was evaluated. One year cumulative survival rate of primary case by Kaplan Meier method was 21.6%, and that of recurrent gastric cancer was 4.5%. The median survival periods were 7 months in primary cases and 4 months in recurrent cases. In primary cases, the arterial infusion therapy was more effective in non-curatively resected cases than in unresectable ones. Intraperitoneal administration of cisplatin with AF intraarterial infusion therapy (AF-CDDP therapy) was applied in 11 cases with 9 primary and 2 recurrent cases. The clinical effectiveness of each was evaluated. One-year cumulative survival rate of primary case by Kaplan-Meier method was 28.6% and the median survival periods were 10 months. AF-CDDP therapy was considered more effective for unresectable gastric cancer with carcinomatous peritonitis. In conclusion, our method is considered to be advantageous in the treatment of carcinomatous peritonitis of gastric cancer patients.
