AIM: To determine characteristics and prognostic predictors of patients with hepatocellular carcinoma (HCC) in association with non-alcoholic fatty liver disease (NAFLD). METHODS: We reviewed the records of all patients with NAFLD associated HCC between 2000 and 2012. Data collected included demographics; histology; presence or absence of cirrhosis, size and number of HCC, alpha-fetoprotein, body mass index (BMI), and the presence of diabetes, hypertension, or dyslipidaemia. RESULTS: Fifty-four patients with NAFLD associated HCC were identified. Mean age was 64 years with 87% male. Fifteen percent (8/54) were not cirrhotic. 11%, 24% and 50% had a BMI of < 25 kg/m2, 25-29 kg/m(2) and >= 30 kg/m(2) respectively. Fifty-nine percent were diabetic, 44% hypertensive and 26% hyperlipidaemic. Thirty-four percent of the patients had <= 1 of these risk factors. Non-cirrhotics had a significantly larger mean tumour diameter at diagnosis than cirrhotics (p = 0.041). Multivariate analysis did not identify any other patient characteristics that predicted the size or number of HCC. CONCLUSION: HCC can develop in NAFLD without cirrhosis. At diagnosis such tumours are larger than those in cirrhotics, conferring a poorer prognosis.
