[Intraperitoneal repeated chemotherapy using CDDP combined with MMC for carcinomatous peritonitis]

Based on our experimental study, which indicated that simultaneous combined administration of MMC and CDDP prolonged life more significantly than individual administration, clinical application was performed on three cases of carcinomatous peritonitis from Borrmann type 4 cancer of the stomach. The dosage was 14 mg/m2 (7 mg/m2 at second and following administrations) of MMC and 35 mg/m2 of CDDP and they were repeatedly administered in the abdominal cavity via the drug delivery system. As the result, no severe toxicities were found except for two cases of leukopenia (Grade 2). Effectiveness was indicated in all cases with the negative change of cytology, whereas no improvements in prognosis were obtained. We concluded that some new devices would be necessary to increase the drug delivery to the carcinomatous wall.
