Demographic Trends in Mortality Related to Gastric Cancer in the United States, 1999 to 2022

Background: Gastric cancer remains one of the leading causes of death globally and a major health concern. This study aims to analyze gastric cancer-related mortality trends over 2 decades. Methods: The CDC WONDER database was used to analyze and stratify de-identified death certificates from 1999 to 2022 across the United States. Trends in age-adjusted mortality rates (AAMR) were assessed using the Joinpoint Regression Program to determine annual percentage changes. Results: Overall, AAMR decreased from 79.26 in 1999 to 44.81 in 2022. Men and older adults had the highest AAMRs. Non-Hispanic (NH) Black or African Americans had the highest AAMR, while NH Whites had the lowest. Geographically, the Northeast had the highest AAMR, and metropolitan areas had higher AAMRs than nonmetropolitan areas. Conclusion: Gastric carcinoma has a poor prognosis, and although the general trend is decreasing across all sociodemographic areas, further research is required for targeted interventions and health policies for high-risk populations.
