Key clinical point: Compared with patients with hepatocellular carcinoma (HCC) due to other causes, a higher proportion of those with nonalcoholic fatty liver disease (NAFLD)-related HCC do not have cirrhosis and lack an indication for HCC surveillance, thus calling for surveillance strategies for patients with NAFLD without cirrhosis but at high risk for HCC.
Major finding: The proportion of patients without cirrhosis was higher among those with NAFLD-related HCC vs. HCC due to other causes (38.5% vs. 14.6%; P < .0001). Before cancer diagnosis, only 32.8% of patients with NAFLD-related HCC underwent HCC surveillance relative to 55.7% of those with HCC due to other causes (odds ratio 0.36; P < .0001).
Study details: This was a meta-analysis of 61 studies including 94,636 patients with HCC related to either NAFLD (n = 15,377) or other causes (n = 79,259).
Disclosures: No funding was received for the study. Some authors declared having stock options from, serving as paid/unpaid consultants or advisory board members for, and receiving royalties or research grants from various organizations.
