Relationship between non-alcoholic fatty liver disease and hepatocarcinoma: An integrative review

This integrative review explores the connection between Non-Alcoholic Fatty Liver Disease (NAFLD) and Hepatocellular Carcinoma (HCC). NAFLD is characterized by the presence of steatosis in more than 5% of hepatocytes in the absence of excessive alcohol consumption (> 20 g/day in men and > 30 g/day in women) or other chronic liver diseases. On the rise globally, the vast majority is associated with risk factors, mainly obesity and type 2 diabetes mellitus. Advanced NAFLD, including non-alcoholic steatohepatitis, emerges as an important precursor to HCC, in some cases, even before the presence of cirrhosis, due in addition, recent studies highlight NAFLD as a main cause of liver transplantation for HCC. Non-invasive diagnostic methods, such as fibroscan liver elastography, exhibit promise for evaluating hepatic steatosis. Therapeutic interventions aim to slow the progression of NAFLD and mitigate the risks of HCC.
