Study for the Evaluation of Risk of hEpatocellular Carcinoma in NonAlcoholic Fatty Liver
Hepatocellular carcinoma (HCC) is the fifth most common solid cancer and the second cause of cancer-related mortality worldwide. Nonalcoholic fatty liver disease (NAFLD), that is hepatic accumulation of fat in excess of 5% not explained by at risk alcohol intake, is projected to become the leading cause of HCC in Western countries within 2025.NAFLD is most frequently caused by insulin resistance due to unhealthy lifestyle. Due to the epidemics of obesity and type 2 diabetes, NAFLD now affects one in three individuals worldwide. NAFLD-HCC frequently develops without overt cirrhosis suggesting that steatosis directly promotes hepatic carcinogenesis.
• Diagnosis of NAFLD or cryptogenic liver disease, allowing a more liberal alcohol intake limit (\<60/40 g/day in M/F), so as to also include subjects with a moderate alcoholic component of liver disease, an important factor given the high epidemiological burden of this group
• Age between 45 and 75 years
• Any of the following criteria:
• F3-F4 fibrosis, determined histologically, or by non-invasive techniques (stiffness \> 7.9 kPa at Fibroscan and positivity at the NAFLD fibrosis score or at APRI or at FIB4), or evidence of cirrhosis deriving from biochemical tests or imaging methods;
• Family history of primary liver cancer in first degree parentage, or carrier status of rare mutations associated with the development of HCC (such as mutations in APOB and TERT)
• Male patient with type 2 diabetes or obesity carrying at least three genetic variants in PNPLA3, TM6SF2, MBOAT7.
• Willingness to sign the informed consent.
