[Neoadjuvant chemotherapy of liver tumors metastasized by sigmoid colon cancer: a case report of CDDP/5-FU intraarterial infusion therapy followed by hepatectomy].

A case of liver tumors metastasized by Sigmoid colon cancer was treated with intrahepatic arterial infusion of CDDP (10 mg) and 5-FU (250 mg) via subcutaneously implanted reservoir. After 20 administrations of CDDP and 5-FU, the tumors in the right lobe of the liver disappeared, but those in the left lobe remained. Therefore left hepatectomy was carried out. Six months after the hepatectomy, a nodule recurrence was disclosed in the right lobe of the liver. With re-elevated serum CEA level, subsequent intrahepatic arterial infusion of CDDP and 5-FU the nodule size reduced with normalization of the serum CEA level.
