As the most common type of primary liver cancer, hepatocellular carcinoma (HCC) is reportedly the third leading cause of cancer-related death globally. Advanced steatotic liver disease (SLD) emerges as the most prominent contributor to HCC worldwide. In this paper, we review the extrahepatic features of metabolic dysfunction-associated SLD that exacerbate the risk for HCC, including insulin resistance, obesity-related factors such as physical inactivity and dietary patterns, as well as influences of genetics, ethnicity, gender-specific hormonal differences, alcohol-associated liver disease (ALD), smoking habits, and alterations in gut microbiota. Additionally, the mechanisms underlying how these extrahepatic features contribute to the development, as well as the detection and surveillance of HCC, are elaborated. With a better understanding of these factors, targeted interventions can be designed to prevent HCC development or ameliorate its clinical outcomes.
