The subjects involved in the present study were 113 patients with hepatocellular carcinomas who had undergone hepatectomy in our hospital during the past 10 years. During the surveillance, 79 of the 113 patients (69.9 %) had recurrence in the residual liver. The cumulative non-recurrence rate at 2 and 5 years was 48.4 % and 18.1 %, respectively and the cumulative survival rate at 2 and 5 years was 83.8 % and 47.5 %, respectively. The recurrence in the residual liver tended to occur in the group with the larger tumor size, in the single nodular surrounding proliferative types and in the aneuploid types. There were no differences in the recurrence rate and state relating to the operative procedure. To improve the prognosis of hepatocellular carcinoma, it is necessary to consider the hepatic functional reserve after hepatectomy, and to make plans for multidisciplinary therapy, including such further treatment as transcatheter arterial embolization, infusion chemotherapy and preoperative percutaneous ethanol injection.
