[Evaluation of intraperitoneal chemotherapy using CDDP combined with MMC in gastric carcinomatous peritonitis].

Based on the experimental studies using Meth A and L 1210 transplantable mouse, which indicated that simultaneous combined administration of MMC and CDDP prolonged life span more significantly than individual administration, clinical application was performed on 14 cases with carcinomatous peritonitis in gastric cancer. One hundred mg of CDDP was administered before the closure of abdomen and drainage tubes were opened 2 hours later. Then, repeated administration of 10 mg/body of MMC and 40-50 mg/body of CDDP was continued once a month via the drug delivery system. Negative change of cytology was observed in seven out of 14 cases, and the prognosis of these patients was better than in the unchanged cytology group. Side effects such as severe gastro-intestinal symptoms and bone marrow toxicities were not recognized. Further studies should be done to confirm the efficacy of the intraperitoneal chemotherapy for carcinomatous peritonitis.
