Infusional versus systemic chemotherapy for liver metastases from colorectal cancer

Abstract

It is clear from these studies that intrahepatic arterial infusion of floxuridine produces significantly higher response rates than does systemic infusion of the same drugs. Nevertheless, survival is the most important consideration when comparing two methods of treatment, and at present, there is only a slightly improved survival rate in those patients who receive intrahepatic infusional therapy. However, palliation of the patient and the effect on the quality of life should be taken into account, and these high response rates suggest an effective palliative measure to be offered to patients with this advanced disease. It is hoped that in the future the development of methods to identify those patients who will respond to this form of therapy, together with new ways to increase drug uptake by the tumors, will translate the better response rates achieved into better survival rates.
