Feasibility of adjuvant hepatic arterial infusion of chemotherapy after radiofrequency ablation with or without resection in patients with hepatic metastases from colorectal cancer.

Background: The safety of combined hepatic artery infusion chemotherapy (HAI) and radiofrequency ablation (RFA) for liver metastases has not been assessed. We conducted a study to determine the feasibility of using HAI after RFA for colorectal cancer (CRC) liver metastases.

Methods: Between 1996 and 2001, patients with hepatic metastases from CRC were enrolled onto a prospective study of RFA plus HAI consisting of continuous-infusion floxuridine and bolus fluorouracil.
