BACKGROUND: When restrictive selection criteria are applied orthotopic liver transplantation (OLT) is the most efficient option for the treatment of hepatocellular carcinoma (HCC) in terms of survival and recurrence rate. Nevertheless, tumor recurrence may occur in 3.5%-21% of recipients, with a consequent negative impact on prognosis. The aim of this study was to analyze the long-term survival and tumor recurrence rate among a cohort of liver transplant recipients with HCC. METHODS: During the period 1994-2007, 130 HCC patients, including 111 males with a mean overall age of 57.8 +/- 7.1 years (range, 38-70), underwent cadaveric donor-OLT. The etiology of liver disease was alcoholic cirrhosis in 66 patients (50.8%) and viral infection in 52 patients (40%). Baseline alpha fetoprotein values were 53.4 +/- 280.9 ng/mL (range, 1-2593). Median interval between inclusion date and transplantation was 179.5 days. RESULTS: After a median follow-up of 40.8 months, 93 recipients (71.5%) were alive. Tumor recurrence was detected in 11 patients (8.5%). Neoplasm recurrence sites were as follows: liver graft (45.4%), bone (36.4%), lymphoadenopathies (27.3%), adrenal glands (27.3%), and lung (27.3%). Overall survival rates at 1, 3, 5, and 10 years were 85.1%, 78.3%, 70.1%, and 57%, respectively. After examination of the explanted liver, Milan criteria were surpassed in 32 recipients (24.6%). Nevertheless, no differences in survival were observed according to fulfilment or not of Milan criteria (log-rank test, P > .05). Hepatitis C virus (HCV) infection, female gender, and tumor recurrence were associated with a worse survival rate (log-rank test, < .05). CONCLUSIONS: OLT is an effective option for the treatment of HCC with good long-term survival and low recurrence rates. In this series, survival was not affected by findings of poor prognostic factors in the explanted liver.
