Abstract
Intra-arterial injection of a suspension of adriamycin and/or mitomycin C in Lipiodol was performed in 17 patients with hepatic metastases, which at angiography were poorly vascularized. Accumulation of Lipiodol in the tumors was demonstrated at computed tomography (CT) in 15 of 17 patients examined within one week. Follow-up with CT showed that Lipiodol remained in the tumor during the first month in 94 per cent, after 2 months in 31 per cent, and after 3 months in 17 per cent. In the non-tumor part of the liver Lipiodol disappeared earlier, and one month after injection it could no longer be traced on CT. In 8/17 cases (47%) CT, after intra-arterial injection of Lipiodol, gave superior information compared with CT after intravenous contrast enhancement. Tumor response was achieved in 9 of 16 cases. Particularly in metastases originating from cancer of the colon and stomach response was observed with a decrease in tumor size in 8 of 10 patients.
