Objectives: The incidence of hepatocellular carcinoma associated with nonalcoholic fatty liver disease is increasing. We sought to compare tumor characteristics and outcomes after a liver transplant according to the cause of liver disease and ethnicity. Materials and Methods: We retrospectively evaluated patients with hepatocellular carcinoma (292, 23%) out of all the liver transplant recipients (N-1266) at the University of Miami between 2000 and 2010. Liver disease was caused by hepatitis C virus in 221 patients (76%), nonalcoholic fatty liver disease in 19 patients (6.5%), hepatitis B virus in 20 patients (7%), alcohol in 44 patients (15%), and other in 18 patients (6%). The median age was 57 years (range, 17 to 77 y), 218 were men (75%), 270 were white (92%), and 92 were Hispanic (31.5%). Results: Patients with hepatocellular carcinoma and nonalcoholic fatty liver disease were more likely to be older (64 vs 57; P -.0006), Hispanic (58% vs 30%; P -.018); nonsmokers (89% vs 65%; P -.041), diabetic (84% vs 26% P <.0001), hypertensive (63% vs 27%; P -.003), and using statins (32% vs 4%; P -.0004) compared with hepatocellular carcinoma without nonalcoholic fatty liver disease. Diabetes, hypertension, and nonalcoholic fatty liver disease are significantly more common in Hispanics than in non-Hispanic persons with hepatocellular carcinoma. In persons without hepatocellular carcinoma, the proportion of Hispanics was similar between those with (n-84) and those without (n-1182) nonalcoholic fatty liver disease. Hispanic ethnicity was not associated with worse tumor behavior or overall survival. Conclusions: Patients transplanted for hepatocellular carcinoma and nonalcoholic fatty liver disease were older, and were more frequently Hispanic than were persons with hepatocellular carcinoma and nonalcoholic fatty liver disease. Hispanic ethnicity may be a risk factor for hepatocellular carcinoma.
