title: Prolonged and continuous percutaneous intra-arterial hepatic infusion chemotherapy in advanced metastatic liver adenocarcinoma from colorectal primary.
abstract: Sixty patients with advanced metastatic adenocarcinoma of the liver from a colorectal primary were treated by prolonged and continuous intra-arterial hepatic arterial infusion chemotherapy over a period of time from December 1969 through July 1976. A 10-day course of 5-FU was administered in the hospital, and patients were discharged receiving 5-FUDR by continuous arterial infusion through a chronometric infusion pump. Objective responses of 100% were obtained in 15% of patients, 50% response in 39% of patients, and 25% response in 21% of patients. The median survival from onset of treatment was 8.5 months, 6.9 months, and 7 months, respectively, for 100%, 50%, and 25% responders versus 3.6 months for nonresponders. Survivals from onset of treatment were generally less in those with no disease-free interval. No relationship of response to sex and age was found. Patients previously treated with 5-FU intravenously responded to intra-arterial chemotherapy; 13% had a 100% response, and 54% had a 50% response. No relationship of drug dose to response was observed. Drug toxicity was frequently systemic and mild to moderate. Numerous complications occurred due to the catheter, complete or partial thrombosis occurring in 18.6% and 20.8%, respectively, and 30% of patients had displacement of the catheter. The role of partial arterial occlusion in terms of response and survival may be significant. Future studies should involve comparison of direct surgical placement versus percutaneous placement of catheters.
