Abstract

BACKGROUND & AIMS: There are limited data on the risk of hepatocellular cancer (HCC) in patients with non-alcoholic fatty liver disease (NAFLD). We aimed to estimate the risk of incident HCC among patients with NAFLD. METHODS: We conducted a retrospective cohort study from a total of 130 facilities in the Veterans Health Administration. Patients with NAFLD diagnosed between January 1, 2004 and December 31, 2008 were included and followed until HCC diagnosis, death, or December 31, 2015. We also identified a sex- and age-matched control cohort without NAFLD. We ascertained all new HCC cases from the Central Cancer Registry and manual chart reviews. We calculated incidence rates for HCC by NAFLD status, as well as in subgroups of NAFLD patients. We used competing risk models to compare the risk of HCC in patients with NAFLD vs those without NAFLD. We reviewed electronic medical records of all HCC cases that developed in NAFLD patients without cirrhosis. RESULTS: We compared 296,707 NAFLD patients with 296,707 matched controls. During 2,382,289 person-years [PYs] of follow-up, 490 NAFLD patients developed HCC (0.21/1000 PYs). HCC incidence was significantly higher among NAFLD patients vs controls (0.02/1000 PYs; hazard ratio, 7.62; 95% confidence interval, 5.76-10.09). Among patients with NAFLD, those with cirrhosis had the highest annual incidence of HCC (10.6/1000 PYs). Among patients with NAFLD cirrhosis, HCC risk ranged from 1.6 to 23.7 per 1000 PYs based on other demographic characteristics; risk of HCC was the highest in older Hispanics with cirrhosis. In medical record reviews, 20% of NAFLD patients with HCC had no evidence of cirrhosis. CONCLUSIONS: Risk of HCC was higher in NAFLD patients than that observed in general clinical population. Most HCC cases in NAFLD developed in patients with cirrhosis. The absolute risk of HCC was higher than the accepted thresholds for HCC surveillance for most patients with NAFLD cirrhosis.

  • In the national Veterans Affairs study, a FIB-4 > 2.67, suggestive of advanced fibrosis (F3/F4), was associated with an increased risk of HCC (0.39/1,000 vs. 0.04/1,000 person-years in individuals with persistently low FIB-4) in the absence of cirrhosis.

    “In the national Veterans Affairs study, a FIB-4 > 2.67, suggestive of advanced fi brosis (F3/ F4), was associated with an increased risk of HCC (0.39/1,000 vs . 0.04/1,000 PY in individuals with persistently low FIB-4) in the absence of cirrhosis. 244”

    The Results (Sensitivity and Subgroup Analyses) report the stated HCC rates: 0.39 versus 0.04 per 1,000 person-years for high versus persistently low FIB-4. But these groups lacked a *documented cirrhosis diagnosis*, not necessarily cirrhosis itself; the same section reports that chart review found cirrhosis or possible cirrhosis in some patients without a documented diagnosis. (LLM, conf=0.86)

  • The HCC incidence in individuals without cirrhosis is very low, ranging from 0.08 to 0.63 per 1,000 person-years.

    “the HCC incidence in individuals without cirrhosis is very low, ranging from 0.08 to 0.63 per 1,000 PY. 240 -244”

    From EASL-EASD-EASO Clinical Practice Guidelines on the management of metabolic dysfunction-associated steatotic liver disease (MASLD). (2024) · cites this paper as [244]

    The Results (Sensitivity and Subgroup Analyses; page unavailable) report a low HCC incidence of 0.08 per 1,000 person-years in NAFLD patients without cirrhosis. The cited paper does not give the claimed upper endpoint of 0.63 per 1,000 person-years, so it supports the low incidence and lower endpoint but not the full range. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Studies in MASLD indicate an elevated HCC risk with FIB-4 > 3.25 (risk > 1%/year) or change of LSM over time in individuals with histologic diagnosis of F3-F4 fibrosis and/or baseline LSM > 10 kPa (HR 1.72) in individuals without cirrhosis.

    “Studies in MASLD indicate an elevated HCC risk with FIB-4 > 3.25 (risk > 1%/year) 244 or change of LSM over time in individuals with histologic diagnosis of F3-F4 fi brosis and/or baseline LSM > 10 kPa (HR 1.72) 185 in individuals without cirrhosis.”

    For the FIB-4 claim attached to this citation, the Methods (Variable Specification; page unavailable) use a high FIB-4 cutoff of ≥2.67, not >3.25. The Results (Sensitivity and Subgroup Analyses; page unavailable) report elevated HCC risk with high FIB-4, but the risk above 1% per year—13.5 per 1,000 person-years—was in patients with documented cirrhosis. The reported rate for high FIB-4 without a cirrhosis diagnosis was 0.39 per 1,000 person-years. The LSM claim is attached to a different citation and is not assessed here. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Factors associated with a higher risk of HCC occurrence in MASLD include presence and duration of T2D, obesity or both, older age, concurrent alcohol intake and/or smoking, FIB-4 > 3.25, and LSM > 10 kPa and increasing change in LSM.

    The Discussion reports higher HCC risk in older patients with NAFLD, and the Results associate high FIB-4 with higher risk. The paper uses a FIB-4 cutoff of ≥2.67, not >3.25. It does not establish the claimed effects of diabetes duration, obesity, concurrent alcohol intake or smoking in this population, or report LSM thresholds or changes. (LLM, conf=0.89)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
