Abstract

Background: About 50% of recurrence after resection of hepatic metastases from colorectal cancer remain confined to the liver. Adjuvant locoregional treatments could reduce the failure rate, but these treatments have been scantily investigated. Experimental models have shown that both intra-arterial chemotherapy (IAC) and intraportal chemotherapy (IPC) in adjuvant setting were able to reduce metastatic growth, but IPC should be initiated in the immediate postoperative period. Aims: To evaluate the feasibility of immediate postoperative IPC of fluorouracil (5-FU) plus folinic acid (FA) in a consecutive series of patients undergoing hepatic resection for metastatic colorectal cancer. Methods: Forty-three consecutive patients underwent hepatic resection. The first 25 (Control Group = CG) received only surgery; the latter 18 (Treated Group = TG) were candidate to postoperative IPC of 5-FU 750 mg/m2 plus FA 20 mg/m2/day continuous infusion for 8 days. One patient was not treated owing to bleeding, thus only 17 received the treatment. Results: Postoperative morbidity was 14%, equally distributed in both groups. Biochemical hepatic parameters of TG were not statistically different from those of CG. Five patients (29%) developed systemic toxicity: one hematologic grade 4; 3 mucositis grade 3 and one allergic erythema. Three of these patients had been treated by systemic chemotherapy less than one year before. Discussion: IPC of 5-FU plus FA in the immediate postoperative period has not yet been tested. The schedule we have investigated neither affected the postoperative outcome, nor influenced hepatic function and regeneration. Systemic toxicity was evident and severe mainly in patients already pretreated by systemic chemotherapy. In these patients, however, toxicity did not affect further outcome. This study confirms the feasibility of immediate intraportal chemotherapy after hepatic resection.
