The role of aggressive regional therapy for colorectal liver metastases.
Surgical resection is the most effective treatment modality for liver metastases from colorectal cancer. However, most patients with liver metastases are not candidates for resection due to extensive intrahepatic disease. Approximately one-half of the patients who are able to undergo resection will eventually recur within the remnant liver. Hepatic arterial infusion (HAI) chemotherapy takes advantage of the arterial blood supply of colorectal liver metastases to increase tumor exposure to chemotherapy while minimizing systemic toxicity. HAI chemotherapy has been utilized in patients with unresectable disease in the neoadjuvant setting in an effort to convert them to resectability as well as in patients with resectable disease in the adjuvant setting in an effort to prevent recurrence. This article reviews the roles of HAI chemotherapy in an aggressive approach toward colorectal liver metastases.
