title: Hepatic artery infusion of chemotherapy as a treatment for hepatic metastases from colorectal cancer.
abstract: Hepatic artery infusion (HAI) of chemotherapy as a treatment for hepatic metastases from colorectal cancer has become more commonly used after the introduction of the totally implantable hepatic artery pump in the early 1970s. Floxuridine (FUDR) is the generally used chemotherapy agent in the pump because of its high solubility and high extraction rates by the liver on the first pass of the chemotherapy through the hepatic circulation. HAI has been used mainly to treat unresectable liver metastases in patients who have liver metastases only. The other scenario for pump use has been as an adjuvant therapy after resection of all metastatic disease inthe liver. The rationale for HAI includes the unique dual blood supply of the liver allowing chemotherapy given into the artery and sparing the normal cells, which get their predominant blood supply from the portal vein. The details of pump design will be reviewed. Complications from HAI are specific for this therapy and will be reviewed. Treatment of unresectable liver metastases with HAI has been the subject of a number of prospective randomized studies. These will be presented, along with newer phase II studies. Three randomized studies on the usefulness of HAI after hepatic resection will be presented.
