Background: s/Aims: The trends in mortality of hepatocellular carcinoma (HCC) and biliary tract cancers stratified by sex and race/ethnicity in the US continue to evolve. We estimated the sex- and race/ethnicity-based trends in HCC and biliary tract cancers-related mortality in US adults with a focus on disease burden. Methods: We performed a population-based analysis using the US national mortality records from 2018 to 2023. We identified HCC and biliary tract cancer using appropriate ICD-10 codes. Temporal trends in mortality were calculated by joinpoint analysis with annual percentage change (APC). Results: Annual age-standardized mortality from HCC decreased steadily with an APC of –1.4% (95% confidence interval [CI]: –2.0% to –0.7%). While there was a linear increase in intrahepatic cholangiocarcinoma-related mortality (APC: 3.1%, 95% CI: 1.2–4.9%) and ampulla of Vater cancer-related mortality (APC: 4.1%, 95% CI: 0.5–7.9%), gallbladder cancer-related mortality decreased (APC: –1.9%, 95% CI: –3.8% to –0.0%). Decreasing trends in mortality from HCC were noted in males, not females. HCC-related mortality decreased more steeply in racial and ethnic minority individuals compared with non-Hispanic White individuals. Racial and ethnic differences in trends in mortality for biliary tract cancers depended on the malignancy’s anatomical site. Conclusions While the annual mortality for HCC and gallbladder cancer demonstrated declining trends, ICC- and AVC-related mortality continued to increase from 2018 to 2023. Although racial and ethnic minority individuals in the US experienced disproportionately higher HCC and biliary tract cancer, recent declines in HCC may be primarily due to declines among racial and ethnic minority individuals and males.

Background/Aims: The global proportion of hepatocellular carcinoma (HCC) attributable to metabolic dysfunction-associated fatty liver disease (MAFLD) is unclear. The MAFLD diagnostic criteria allows objective diagnosis in the presence of steatosis plus defined markers of metabolic dysfunction, irrespective of concurrent liver disease. We aimed to determine the total global prevalence of MAFLD in HCC cohorts (total-MAFLD), including the proportion with MAFLD as their sole liver disease (single-MAFLD), and the proportion of those with concurrent liver disease where MAFLD was a contributary factor (mixed-MAFLD). Methods: This systematic review and meta-analysis included studies systematically ascertaining MAFLD in HCC cohorts, defined using international expert panel criteria including ethnicity-specific BMI cut-offs. A comparison of clinical and tumour characteristics was performed between single-MAFLD, mixed-MAFLD, and non-MAFLD HCC. Results: 22 studies (56,565 individuals with HCC) were included. Total and single-MAFLD HCC prevalence was 48.7% (95% confidence interval [CI] 34.5–63.0%) and 12.4% (95% CI 8.3–17.3%), respectively. In HCC due to chronic hepatitis B, C, and alcohol-related liver disease, mixed-MAFLD prevalence was 40.0% (95% CI 30.2–50.3%), 54.1% (95% CI 40.4–67.6%) and 64.3% (95% CI 52.7–75.0%), respectively. Mixed-MAFLD HCC had significantly higher likelihood of cirrhosis and lower likelihood of metastatic spread compared to single-MAFLD HCC, and a higher platelet count and lower likelihood of macrovascular invasion compared to non-MAFLD HCC. Conclusions MAFLD is common as a sole aetiology, but more so as a co-factor in mixed-aetiology HCC, supporting the use of positive diagnostic criteria.
