Background: Hepatocellular carcinoma (HCC) is the fifth most common and the third most deadly cancer worldwide, with more than half a million identified cases and about a similar number of subjects succumb to it each year. This study sought to evaluate our results of liver transplantation for HCC to identify prognostic factors.
Methods: Between December 2001 and December 2006, 224 patients (205 men, 19 women; age range, 15-75 years) with HCC underwent orthotopic liver transplantation (OLT) at our center. All grafts were from deceased donors. There were 68 cases within Milan criteria (30.3%), 32 cases beyond Milan criteria but within UCSF (University of California, San Francisco) criteria (14.3%), and 124 cases beyond UCSF criteria (55.4%).
Results: The overall 1-, 3-, and 5-year patient cumulative survival rates were 82.5%, 60.1%, and 51.5%, respectively. The survival rates were comparable between patients within Milan and UCSF criteria, but were significantly greater than that of patients beyond UCSF criteria. Multivariate analysis revealed alpha fetoprotein (AFP) >or= 800 microg/L, vascular invasion, and poor tumor differentiation to be independent prognostic factors.
Conclusion: OLT is a safe and effective treatment for hepatitis B virus-related HCC. Compared with Milan criteria, UCSF criteria successfully expanded the indication without deteriorating the prognosis significantly, while preoperative AFP >or= 800 microg/L, vascular invasion, and poor tumor differentiation indicated poor survival.
