Evaluation of treatment for gastric cancer with liver metastasis

In 161 cases of gastric cancer with liver metastasis but without peritoneal dissemination, evaluations were executed to find effective treatment. The most favorable results with best prognosis were obtained in the group receiving gastrectomy + hepatectomy + chemotherapy, followed by gastrectomy + chemotherapy, and gastrectomy alone. The most unfavorable outcome was in nonresected cases. Chief chemotherapy to be used after gastrectomy was FML (5-fluorouracil (5-FU) + mitomycin C [MMC] + lentinan) continuous intra-arterial infusion. Hepatectomy was found to be effective as an active measure for tumor reduction in cases of liver metastasis so far as the metastatic lesions are only a few scattered ones in both lobes.
