Abstract

Background and Aims: Recent studies link NAFLD to an increased incidence of HCC and extrahepatic cancers. However, earlier studies were small or lacked liver histology, which remains the gold standard for staging NAFLD severity. Approach and Results: We conducted a population‐based cohort study of all adults with histologically defined NAFLD in Sweden from 1966 to 2016 (N = 8,892). NAFLD was defined from prospectively recorded liver histopathology submitted to all 28 Swedish pathology departments and categorized as simple steatosis, nonfibrotic NASH, noncirrhotic fibrosis, and cirrhosis. NAFLD patients were individually matched to ≤5 general population controls without NAFLD by age, sex, calendar year, and county (N = 39,907). Using Cox proportional hazards modeling, we calculated multivariable adjusted HRs (aHRs) and 95% CIs. Over a median of 13.8 years, we documented 1,691 incident cancers among NAFLD patients and 6,733 among controls. Compared with controls, NAFLD patients had significantly increased overall cancer incidence (10.9 vs. 13.8 per 1,000 person‐years [PYs]; difference = 2.9 per 1,000 PYs; aHR, 1.27 [95% CI, 1.18‐1.36]), driven primarily by HCC (difference = 1.1 per 1,000 PYs; aHR, 17.08 [95% CI, 11.56‐25.25]). HCC incidence rates increased monotonically across categories of simple steatosis, nonfibrotic NASH, noncirrhotic fibrosis, and cirrhosis (0.8 per 1,000 PYs, 1.2 per 1,000 PYs, 2.3 per 1,000 PYs, and 6.2 per 1,000 PYs, respectively; P trend < 0.01) and were further amplified by diabetes (1.2 per 1,000 PYs, 2.9 per 1,000 PYs, 7.2 per 1,000 PYs, and 15.7 per 1,000 PYs, respectively). In contrast, NAFLD was associated with modestly increased rates of pancreatic cancer, kidney/bladder cancer, and melanoma (differences = 0.2 per 1,000 PYs, 0.1 per 1,000 PYs, and 0.2 per 1,000 PYs, respectively), but no other cancers. Conclusions: Compared with controls, patients with biopsy‐proven NAFLD had significantly increased cancer incidence, attributable primarily to HCC, whereas the contribution of extrahepatic cancers was modest. Although HCC risk was highest with cirrhosis, substantial excess risk was also found with noncirrhotic fibrosis and comorbid diabetes.

  • Cancer-related mortality is among the leading causes of mortality in NAFLD patients, mainly driven by extrahepatic malignancies followed by hepatocellular carcinoma.

    “cancer‐related mortality is among the leading causes of mortality in NAFLD patients, mainly driven by extrahepatic malignancies followed by hepatocellular carcinoma [23, 24].”

    From Current treatment of non‐alcoholic fatty liver disease (2022) · cites this paper as [23]

    The introductory passage (indexed under Abstract; page unavailable) says mortality from both extrahepatic cancers and HCC has increased among patients with NAFLD. It does not establish that cancer is a leading cause of death or that extrahepatic malignancies account for more cancer deaths than HCC. The Discussion addresses cancer incidence, not that mortality ranking. (LLM, conf=0.82)

  • T2D is associated with poor outcomes in individuals with biopsy-proven MASH and compensated cirrhosis, including a 4-fold increased risk of death and an approximately 2-fold increased risk of liver-related outcomes including HCC over a median follow-up of 5 years.

  • In a study of histologically confirmed MASLD in Sweden, the overall HCC rate varied with advancing stage of MASLD: 0.8 in simple steatosis, 1.2 in MASH without fibrosis, 2.3 in fibrosis F1-F3 without cirrhosis, and 6.2 in cirrhosis per 1,000 person-years.

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.
