Abstract
Transarterial injection of modified iodized oil was performed in 48 patients with hepatoma. In 41 cases an adriamycin and/or mitomycin C-iodized oil suspension was administered into the proper hepatic artery or peripheral hepatic branches. A reduction in tumor size of over 50 per cent was obtained in 14 of the 33 patients in whom CT examination was performed before and after treatment. Serum alpha-fetoprotein levels decreased in 20 of 21 cases within the first month after injection. The one-year survival rate was estimated at 55 per cent in advanced hepatoma. In 7 patients, transarterial internal irradiation using radioactive iodized oil was carried out. A decrease in tumor size was observed in all cases and in alpha-fetoprotein levels in 6 cases. One patient with severe liver cirrhosis died in hepatorenal failure. No severe complications or other adverse reactions were encountered with either of the methods.
