Burden and trends of nonalcoholic steatohepatitis-related liver cancer in China: A population-based observational...

To comprehensively understand the disease burden of NASH-related liver cancer (NRLC) in China, we analyzed and evaluated the disease burden of NRLC in mainland China from 1990 to 2021 and predicted the trend in its health burden over the next 20 years. We characterized the burden of NRLC in China using the Global Burden of Disease (GBD) 2021 method and results based on incidence, prevalence, mortality, disability-adjusted life years (DALYs), years of life lost (YLLs), and years lived with disability (YLDs). Joinpoint and age-period-cohort (APC) analysis methods were used to interpret the epidemiological characteristics and compare them with global prevalence trends. Moreover, the Bayesian age-period-cohort model was used to predict the incidence of mortality in different age groups over the next 20 years. From 1990 to 2021, the age-standardized incidence rates of males and females in China changed from 4.75 (95% confidence interval [CI]: 3.81-5.81) to 5.42 (95% CI: 4.18-6.85), and the mortality rate changed from 5.02 (95% CI: 4.01-6.14) to 5.06 (3.88, 6.42) per 100,000 people. The age-standardized DALY rate in China has decreased from 133.91 (95% CI: 107.69-163.99) per 100,000 people in 1990 to 122.20 (95% CI: 94.14-154.42) per 100,000 people in 2021. The average annual percentage changes (AAPCs) in the age-standardized incidence, prevalence, and mortality of NRLC in China were 0.44 (95% CI: 0.34-0.54), 1.00 (95% CI: 0.75-1.25), and 0.13 (95% CI: -0.36 to 0.61), respectively. Age, period, and cohort had different effects on the incidence and mortality. Personally, middle-aged and elderly men should pay more attention to the prevention of NRLC. Given the large population, growing SDI index, and aging trend in China, multiple prevention policies and popular education programs should be considered in the near future to minimize the burden of NRLC.
