Abstract
BACKGROUND: Metabolic dysfunction-associated steatotic liver disease (MASLD) affects over 30% of the general population and is the fastest growing cause of hepatocellular carcinoma (HCC). Current guidelines recommend HCC surveillance in patients with cirrhosis when annual HCC incidence exceeds 1% without specifying the role of non-invasive tests in patient selection. OBJECTIVE: To define non-invasive test thresholds to select patients with MASLD for HCC surveillance. DESIGN: A multicentre longitudinal study of adults with MASLD from 16 tertiary centres in the USA, Europe and Asia between February 2004 and January 2023. Primary outcome was incident HCC. RESULTS: 12 950 patients had Fibrosis-4 index (FIB-4) and liver stiffness measurement (LSM) (mean age 51.7 years; 41.1% male). At a median follow-up of 47.7 (IQR 23.3-72.3) months, 109 (0.8%) developed HCC. FIB-4 was below the low cut-off (<1.3 if aged <65 years and <2.0 if aged ≥65 years), between the low cut-off and <2.67, 2.67 to <3.25, and ≥3.25 in 66.3%, 23.9%, 3.4% and 6.4% of patients; the corresponding annual HCC incidence was 0.07%, 0.17%, 0.77% and 1.18%. As a stand-alone test, the annual HCC incidence exceeded 0.2% for LSM ≥10 kPa and 1% for LSM ≥20 kPa. If LSM was performed as a second step only among patients with FIB-4 above the low cut-off, the annual HCC incidence exceeded 0.2% for LSM ≥10 kPa and 1% for LSM ≥15 kPa. CONCLUSION: HCC surveillance should be offered to patients with MASLD with FIB-4 ≥3.25 or LSM ≥20 kPa. When a two-step approach is adopted, LSM ≥15 kPa in patients with increased FIB-4 predicts a high HCC risk.
