RESUMO
Hepatocellular carcinoma is one of the most common malignancies worldwide. Liver transplantation has emerged as a good option for early-stage hepatocellular carcinoma yielding survival rates as good as for recipients without this type of tumor. OBJECTIVE: To assess the outcome of cirrhotic patients with hepatocellular carcinoma undergoing liver transplantation at the Liver Transplantation Service of the "Hospital de Clinicas", Federal University of Parana, Curitiba, PR, Brazil. METHODS: Retrospective study of cirrhotic patients with hepatocellular carcinoma undergoing orthotopic liver transplantation at the mentioned Institution between September 1991 and September 2000. The diagnosis of hepatocellular carcinoma was established during the pretransplant workup in five patients and the tumor was an incidental finding in the native liver in three. The indication for liver transplantation was restricted to solitary tumor equal to or less than 5 cm or up to 3 nodules, with each nodule measuring less than 3 cm, and no evidence of vascular invasion or extrahepatic spread. Patient survival and evidence of tumoral recurrence posttransplant were evaluated. RESULTS: The most common cause for pretransplantation liver disease was hepatitis C virus (50%). On examination of the explanted liver, the majority of patients (6/8, 75%) had a single lesion; one patient had two nodules and one had a multifocal hepatocellular carcinoma found incidentally in the native liver. Tumor size ranged from 0.2 to 5.0 cm. All cases had neither vascular invasion nor linfonodal envolvement. All patients remained alive and free of tumor recurrence at the time of the study with a mean follow-up of 18.5 months (range, 5-29 months). CONCLUSION: Liver transplantation is a good therapeutic option for early stage hepatocellular carcinoma arising in cirrhotic patients. With proper selection, liver transplantation can offer excellent survival rates free of tumor recurrence
