Management of non-alcoholic fatty liver disease-associated hepatocellular carcinoma

Xu PJ, Liu MY, Liu M, Shen A

In recent years, with the decline in HBV and HCV infections, there has been a corresponding reduction in both the morbidity and mortality of virus-associated HCC. Nevertheless, rising living standards, coupled with the increasing prevalence of metabolic disorders like diabetes and obesity, have led to a rapid surge in non-alcoholic fatty liver disease-associated hepatocellular carcinoma (NAFLD-HCC) incidence. The mechanisms underlying the progression from NAFLD to NAFLD-HCC are multifaceted and remain incompletely understood. Current research suggests that genetic predisposition, metabolic dysregulation, lipotoxicity, oxidative stress, and inflammation are key contributing factors. Given the complexity of these mechanisms and the frequent occurrence of metabolic comorbidities like type 2 diabetes mellitus (T2DM) and cardiovascular disease in NAFLD-HCC patients, there is a pressing need for tailored therapeutic strategies, along with novel prevention, monitoring, and treatment approaches that are personalized to the patient's pathophysiology. Due to the limited depth of research, incomplete understanding of pathogenesis, and insufficient clinical data on NAFLD-HCC treatment, current therapeutic approaches largely rely on tumor staging. In this review, we synthesize current research on the pathogenesis, surveillance, diagnosis, treatment, and prevention of NAFLD-HCC, and offer perspectives for future studies, particularly regarding its underlying mechanisms.
