[A case of colon carcinoma with unresectable multiple liver metastases responding to various combined chemotherapies centering on hepatic arterial infusion therapy].

We have experienced a case of colon carcinoma with unresectable multiple liver metastases responding to various combined chemotherapies centering on hepatic arterial infusion therapy. A 42-year-old female with descending colon carcinoma and synchronous unresectable multiple liver metastases underwent left hemicolectomy in September 2001. She was treated with chemotherapy centering on hepatic arterial infusion (HAI) following implantation of a reservoir in the outpatient setting. Pharmacokinetic modulating therapy (PMC), and HAI with Leucovorin/CDDP/5-FU and Levoforinate/CDDP/5-FU were conducted sequentially. Alternative HAI of 5-FU with intravenous infusion of Levoforinate and systemic irinotecan/CDDP were continued biweekly after release of the hepatic artery occlusion. Liver metastases shrunk after 6 months of treatment and were remarkably decreased in size in May 2003. Although 3 metastatic lesions existed in both lungs, good quality of life has been maintained in the 2 years following surgery.
