Background & Aims:
Metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH) are the leading causes of liver disease and are emerging as the main risk factors for primary liver cancer (PLC). However, updated global data on MASH remain scarce.
Methods:
This study analyzed data from the Global Burden of Disease study between 2000 and 2021 to assess the age-standardized incidence, mortality, and disability-adjusted life years (DALYs) from MASH-associated PLC, stratified by geographical region, sociodemographic index, age, and sex.
Results:
There were 42,290 incident cases, 40,920 deaths, and 995,470 DALYs from PLC globally. Global incidence (+98%), death (+93%), and DALYs (+76%) from MASH-associated PLC increased steeply over the study period. Among different etiologies, only MASH-associated PLC had increased mortality rates (annual percent change [APC], +0.46; 95% confidence interval [CI], 0.33%-0.59%). Africa and low sociodemographic index countries exhibited the highest age-standardized incidence, death, and DALYs from MASH-associated PLC. DALYs increased in females (APC, 0.24%; 95% CI, 0.06%-0.42%), whereas they remained stable in males. Americas experienced the highest percentage increase in age-standardized incidence rate (APC, 2.09%; 95% CI, 2.02%-2.16%), age-standardized death rate (APC, 1.96%; 95% CI, 1.69%-2.23%), and age-standardized DALYs (APC, 1.96%; 95% CI, 1.63%-2.30%) from MASH-associated PLC.
Conclusions:
Over the past 2 decades, the burden of MASH-associated PLC has risen, though there are sociodemographic and geographic disparities. This necessitates urgent strategies across the globe to mitigate the epidemic of MASH-associated PLC as well as its metabolic drivers.
Insights
The global burden of primary liver cancer (PLC) linked to metabolic dysfunction-associated steatohepatitis (MASH) has significantly increased over two decades. Urgent global strategies are needed to address MASH-associated PLC and its metabolic drivers, considering existing disparities.
Area of Science:
- Hepatology
- Global Health
- Cancer Epidemiology
Background:
- Metabolic dysfunction-associated steatotic liver disease (MASLD) and steatohepatitis (MASH) are primary drivers of liver disease and increasingly linked to primary liver cancer (PLC).
- Updated global data on MASH-associated PLC are crucial for understanding disease burden and trends.
Purpose of the Study:
- To analyze global trends in the incidence, mortality, and disability-adjusted life years (DALYs) of MASH-associated PLC from 2000 to 2021.
- To identify geographic, sociodemographic, age, and sex disparities in MASH-associated PLC burden.
Main Methods:
- Utilized the Global Burden of Disease study data spanning 2000-2021.
- Assessed age-standardized incidence, mortality, and DALYs for MASH-associated PLC.
- Stratified analyses by region, sociodemographic index, age, and sex.
Main Results:
- Global incidence, deaths, and DALYs from MASH-associated PLC rose significantly (98%, 93%, and 76% respectively).
- MASH-associated PLC demonstrated increasing mortality rates, unlike other etiologies.
- Africa and low sociodemographic index countries bore the highest burden; the Americas showed the fastest growth in incidence and mortality.
Conclusions:
- The burden of MASH-associated PLC has substantially increased globally over the past two decades.
- Significant sociodemographic and geographic disparities exist, highlighting inequities in disease impact.
- Urgent, coordinated global strategies are imperative to combat the MASH-associated PLC epidemic and its underlying metabolic factors.
