Fluoropyrimidine-HAI (hepatic arterial infusion) versus systemic chemotherapy (SCT) for unresectable liver metastases from colorectal cancer.

Although locoregional treatments such as hepatic arterial infusion (HAI) claim the advantage of delivering higher doses of anticancer agents directly into the metastatic organ as compared to systemic chemotherapy (SCT), the benefit in terms of overall survival (OS) is unclear. We quantitatively summarized the results of randomised controlled trials (RCT) comparing HAI to SCT for the treatment of unresectable liver metastatic disease from colorectal cancer (CRC).
