Intraarterial Chemotherapy for Liver Metastases

Colorectal cancer (CRC) is one of the leading cancers globally in terms of both incidence and cancer-related mortality. Liver metastatic disease is the main prognostic driver for patients with CRC. The management options for liver metastatic CRC continue to evolve, particularly with the incorporation of locoregional therapies into the treatment paradigm. Hepatic arterial infusion (HAI) chemotherapy is one such liver directed approach used with the goal of converting patients to liver resection, reducing the risk of recurrence, treating recurrent disease, and most importantly improving overall survival. This article summarizes the role of HAI chemotherapy in the treatment of liver metastatic CRC.
