Hepatic arterial infusion of 5-fluorouracil in combination with subcutaneous interferon-alpha for advanced hepatocellular carcinoma

Abstract

Background/aims: Transcatheter arterial chemoinfusion (TACI) is the main therapeutic modality for advanced hepatocellular carcinoma (HCC) with portal thrombus. However, TACI is not sufficient to improve prognosis. In this study, we evaluated the response to hepatic arterial infusion of 5-fluorouracil (5-FU) in combination with subcutaneous interferon (IFN)-alpha in patients with advanced HCC.

Methodology: Ten patients (men, 8; women, 2; mean age, 55-77) with advanced HCC were enrolled in this study. Hepatic arterial infusion of 5-FU (500 mg/24 hrs) was performed for 5 days on the first and second week. IFN-alpha (5 x 10(6) International Units) was subcutaneously administered three times a week for 4 weeks (1 therapeutic course). Response to therapy was evaluated by abdominal computed tomography at the end of two courses of therapy.

Results: Seven patients received more than two courses of therapy. One patient (14%) showed complete response (CR). Four patients had stable disease (SD) (57%) and the remaining 2 patients had progressive disease (PD) (29%). Tumor markers decreased in all patients except 1 with PD. The 6-month survival rate was 40%. Therapy was discontinued in 3 patients due to severe adverse effects; all of these patients were over 70 years old, and had moderate liver dysfunction (Child-Pugh score of Grade B) before initiation of therapy.

Conclusions: The goal of the therapy with hepatic arterial infusion of 5-FU in combination with subcutaneous IFN-alpha was attained in only 14% among our advanced HCC patients. The tumor completely disappeared in 1 patient, suggesting that this therapeutic modality may be of potential benefit in advanced HCC patients. However, this therapy should be performed with caution in patients with poor hepatic function (grade B or C of Child-Pugh score) and in those more than 70 years old.
