title: Percutaneous hepatic arterial infusion (HAI) of mitomycin C and floxuridine (FUDR): an effective treatment for metastatic colorectal carcinoma in the liver.
abstract: The response rate of metastatic colorectal carcinoma confined to the liver to HAI of FUDR alone is at the range of 50% and to mitomycin C by hepatic arterial infusion (HAI) at the range of 35%. Mitomycin C was added to FUDR by continuous infusion and given by HAI to 12 patients with colorectal cancer confined to the liver. Catheters were placed subselectively in the hepatic artery, and infusion continued for five to six days when the catheter was removed. Cycles were repeated every 30 days. Chemotherapy consisted of mitomycin C 15 mg/m2 administered on day 1 followed by FUDR 100 mg/m2 by continuous infusion daily for five days. Response to treatment was evaluated by serial determinations of plasma CEA and by imaging techniques consisting of a computerized tomography, sonography, and radionuclide scanning of liver as well as by angiography. In 2 patients, complete remission was achieved; in 4 patients a 75% and in another 4 patients a 50% decrease in liver metastasis was observed, while 2 patients had stable disease. Thus, a response rate of 83% with a median duration of six to seven months was achieved. The median survival of the these patients was 16 months. Eight of the 12 patients have failed previous, i.v. 5-FU containing regimens. Complications related to 45 treatment cycles were the following: catheter displacement in 11.1%, an intimal tear, usually in the hepatic artery in 4.4%, gastric ulcerations in 5.4%, and septicemia in 2.7% of the cycles. In addition, aneurysmal dilation of the hepatic artery occurred in 4 patients (8.8% of the treatment cycles), all of whom continued treatment. Chemotherapy-related complications included primarily thrombocytopenia and stomatitis. Mitomycin C + FUDR by hepatic arterial infusion is an effective treatment for colorectal carcinoma metastatic to the liver. The high response rate justifies the adjuvant treatment of Dukes class C colon cancer patients with this treatment.
