We treated primary unresectable hepatic colorectal metastases by hepatic arterial chemotherapy (HAC) combined with resection of the tumor. Patients underwent a resection of the primary colorectal tumor and a placement of HAC system, and received a 5-fluorouracil (5FU) administration once a week (320 mg/m(2)/day). Five patients underwent a 'second-look' hepatectomy in this series. Their shrinkage rate of the primary lesion ranged from 80-99%, as seen by computed tomography. The resected liver tumors were characterized as p53-positive and proliferating cell nuclear antigen-positive. The levels of fluorodeoxyuridylate (FdUMP) and thymidylate synthetase inhibition were low in the tumor tissue. These results might reflect a kind of resistance to 5FU therapy. Hepatectomy is one of the possible options to eradicate the residual SFU-resistant component of the malignancy. Our preliminary experience possibly indicates longer survival from combination approach than from HAC alone.
