Burden of Gastric Cancer in China from 1990 to 2023
TL;DR
While China has achieved substantial reductions in gastric cancer burden over 34 years, emerging challenges include trend reversals in females and persistent sex disparities, necessitating targeted prevention strategies.
Abstract
Objectives To comprehensively assess the gastric cancer burden in China over the past three decades and analyze its epidemiological trends to inform control strategies. Study design This was a population-based observational study that systematically evaluated the burden of gastric cancer in China from 1990 to 2023, utilizing data from the Global Burden of Disease (GBD) 2023 study. Methods We evaluated gastric cancer burden metrics from GBD 2023, including incidence, mortality, YLLs, YLDs, and DALYs. Joinpoint regression and age-period-cohort modeling were employed to analyze trends and epidemiological characteristics. Results Between 1990 and 2023, the age-standardized incidence rate decreased from 54.23 to 25.04 per 100,000 , and mortality decreased from 50.93 to 16.62 per 100,000. Joinpoint analysis showed an average annual percentage change of -2.8% in incidence, with a significant trend reversal in females during 2020-2023. Age-period-cohort analysis revealed peak risk at 65-69 years and lower risk in recent birth cohorts. Conclusions While China has achieved substantial reductions in gastric cancer burden over 34 years, emerging challenges include trend reversals in females and persistent sex disparities, necessitating targeted prevention strategies.
