| Abstract: | The prognosis of hepatocellular carcinoma after hepatic resection remains poor. The major cause is postoperative recurrence, most frequently intrahepatic. During the past 7 years, we conducted a detailed study of recurrence after hepatectomy in 34 patients with solitary small hepatocellular carcinoma measuring no larger than 4 cm in diameter, in which 13 cases had postoperative recurrent tumors. and two cases were considered multicentric. Eighty-five percent of recurrences were diagnosed at 6–18 months after the operation. The cumulative recurrence rates were 61% at 5 years after operation. When analyzing the factors affecting recurrence, a significant difference was observed regarding tumor diameter. After recurrence, most patients underwent percutaneous ethanol injection treatment and/or transcatheter arterial chemoembolization and lipiodolization. Four patients died of progressive disease within 1 year after recurrence; the treatment thus seemed to have no effect. The other patients with recurrence remain alive with the disease. The overall cumulative survival rates in this series were 76% at 3 years and 60% at 5 years after operation. To obtain better results after hepatectomy, even for small hepatocellular carcinoma, careful, long-term follow-up evaluation is therefore necessary for the multidisciplinary treatment of the postoperative recurrence, as well as the early diagnosis of tumors in high-risk patients. © 1996 Wiley-Liss, Inc. |
