Twelve of the patients with advanced (Stage III or IV) hepatocellular carcinoma who received transcatheter chemoembolization survived for more than 5 years. These survivors consisted of 6 Stage III cases and 6 Stage IV cases. Of the 6 Stage III cases, 5 had multiple tumors (larger than 2 cm) in one lobe of the liver, and 1 had tumor invasion into the second portal branch before treatment. Of the 6 Stage IV cases, 4 had had multiple tumors in both lobes, and 2 had had tumor invasion into the main portal branches. Before treatment, 9 of the 12 survivors had been rated as Child's class A. Lipiodol was used in all 12 cases. The results of the present study suggest the usefulness of Lipiodol in treating advanced hepatocellular carcinoma.
