[A case of liver metastasis from retroperitoneal leiomyosarcoma successfully treated by intra-arterial infusion chemotherapy of adriamycin or epirubicin using an implantable reservoir].

A 59-year-old woman was diagnosed as having liver metastasis (H3) 38 months after undergoing resection for retroperitoneal leiomyosarcoma. A catheter was placed in the hepatic artery and intra-arterial infusion chemotherapy using an implantable reservoir was performed with 30 mg of adriamycin or epirubicin at each treatment every 2-4 weeks. Imaging revealed that the tumor had been markedly reduced, and a partial response was obtained for 18 months. The patient has survived for 33 months since liver metastasis was detected. Although effective chemotherapy for metastatic leiomyosarcoma in the liver has been poorly documented, intra-arterial infusion chemotherapy proved highly effective in this case, suggesting that it effectively improved the prognosis.
