Abstract

Thousands of patients die annually from unresectable metastatic or primary hepatic cancers confined to liver. Isolated hepatic perfusion (IHP) is a regional treatment strategy in which the vascular supply to the liver is isolated and perfused with a therapeutic regimen using an extracorporeal circuit consisting of a reservoir, heat exchanger, and oxygenator. Drug doses that would cause severe toxicities if delivered systemically can be confined to the liver by isolated hepatic perfusion, resulting in the ability to intensify treatment to the cancer-burdened region of the body. Agents and mechanisms commonly used in IHP include melphaIan, hyperthermia, and tumor necrosis factor. IHP appears to be efficacious for patients with advanced disease, as reflected by large tumor size, high number of lesions, or significant overall tumor burden in the liver. In addition, responses are observed for patients whose cancer is refractory to systemic and hepatic arterial infusion chemotherapy. Recent clinical trials have demonstrated that IHP has anti-tumor efficacy against primary hepatic neoplasms and metastases from various primary tumors, such as colorectal carcinoma, ocular melanoma, and neuroendocrine tumors. Current studies demonstrate that combining hepatic arterial infusion with floxuridine after IHP for patients with colorectal cancer metastases is associated with significant and durable response rates. Continued clinical evaluation is warranted for the use of IHP in the treatment of unresectable liver metastases.
