Hepatic arterial infusion (HAI) chemotherapy is accepted to be an option in patients with non-resectable metastases from colorectal cancer confined to the liver. In a multi-istitutional trial, 76 patients were randomly assigned to receive HAI versus HAI plus systemic bolus 5-fluorouracil and leucovorin. The primary end-point was survival followed by response, recurrence and toxicity. Survival was longer for HAI plus systemic chemotherapy (HAI+SYC) than HAI (median, 20 vs. 14 months; p=0.0033), as were responses (47.5% and 41.7%; p=0.09) and time to hepatic progression (12 vs. 8 months; p=0.039). Side effects included haematological toxicity that was mostly mild and reversible in 432 cases. Neutropenia grade 3 occurred in four patients in the HAI+SYC arm and one in the HAI arm. Diarrhoea occurred in 20% and 7% of patients and stomatitis occurred in 18% and 2%, respectively. On the contrary biliary toxicity was significant; twelve patients had evidence of bilirubin elevations of more than 3 mg/dl (six in each arm), and two had asymptomatic arterial biliary-tree fistulae: one in the HAI+SYC arm and one in the HAI arm. Grade 3 elevation in alkaline phosphatase and aminotransferase levels occurred in 26% and 24%, respectively. In conclusion, the combination of HAI+SYC is active and safe showing a clinical advantage with respect to simple HAI, increasing overall survival response rate and time to progression.
