Intra-arterial hepatic chemotherapy for metastatic liver from colo-rectal carcinoma origin.

Abstract

Loco-regional intra-arterial chemotherapy of hepatic metastases from colo-rectal cancer is one of the most effective non-surgical treatments in this clinical situation. In our experience of 58 cases treated during 3 years, in a non randomized study by either: 1) discontinuous perfusion of 5FU (using a subcutaneous access) or 2) by continuous infusion of FUDR (using an implantable pump), we observed an objective response rate of 52% and 53% with a 1 year survival of 73% and 90%, respectively. This technique, however, is limited in its application by loco-regional complications and in its long term efficacy by the development of extrahepatic metastases. The proof of its efficacy in terms of survival prolongation, is being studied within the framework of a prospective randomized trial with a control group.
