[Clinical study of combination chemotherapy using carboquone, cisplatin, UFT and OK-432 in 7 cases of advanced gastric cancers and a relapsed gastric cancer].

In 8 cases of advanced and/or relapsed gastric cancer (7 cases advanced, 1 case relapsed), we undertook combination chemotherapy with systemic administration of cisplatin and celiac arterial infusion of carboquone intermittently under continuous administration of OK-432 i.m. and UFT p.o. The male to female ratio was 5 to 3 and the age distribution from 53 to 77 years (mean age, 70 years.) Eight cases were divided into the following histological types: 1 papillary adenocarcinoma, 1 well-differentiated tubular adenocarcinoma, 3 moderately differentiated tubular adenocarcinomas, and 3 poorly differentiated adenocarcinomas. Complete response (CR) was obtained in one case, partial response (PR) in four cases, minor response (MR) in two cases, and no change (NC) in one case. The response rate was 62.5%. CR was noted in a relapsed case. The median survival time from the beginning of the chemotherapy was 8 months (ranging from 6 to 13 months). The major toxicity was bone marrow suppression, but there were no cases of serious renal damage.
