    Abstract:
    Ninety-three patients with biopsy-proven colorectal cancer metastatic to the liver were treated with hepatic arterial infusion of 5-fluorodeoxyuridine (FUDR). There were 52 men and 41 women (median age, 60 years). Forty-two patients (45%) had failed prior systemic chemotherapy. Catheters were operatively placed and multiple catheters were used if dictated by hepatic arterial anatomy in order to obtain perfusion of the entire liver. The drug was delivered by a totally implanted INFUSAID model 400 pump and patients received cyclic therapy consisting of 2 weeks of 0.3 mg/kg/d FUDR alternating with 2 weeks of saline. Patients with extrahepatic tumor or patients whose hepatic tumor failed to respond to FUDR were given a 30 minute intraarterial infusion of mitomycin C, 15 mg/m2, every 6 to 8 weeks in addition to FUDR. Fifty of the 93 evaluable patients presented with metastatic tumor confined to the liver. Of these 50 patients, 83% demonstrated a significant reduction in tumor size with a median duration of response of 13 months and a median survival of 25 months from diagnosis of liver metastases. Twenty-four of these 50 patients remain alive. Forty-three patients presented with extrahepatic metastases in addition to their liver tumor, and 74% had a response with a median duration of 6 months and a median survival of 14 months. Only six patients of those presenting with extrahepatic tumor remain alive. None of the 93 patients died solely of uncontrolled liver tumor, and only 9 died as a result of uncontrolled liver metastases and disseminated extrahepatic tumor. The duration of survival for both groups was determined by the uncontrolled progression of extrahepatic tumor. In patients with metastatic colorectal cancer involving only the liver, hepatic arterial FUDR alone and with the addition of mitomycin C provided excellent control of hepatic tumor. Survival appeared to be prolonged in this uncontrolled study.
