BACKGROUND: Gastric cancer remains a significant cause of mortality worldwide. This study analyzed gastric cancer mortality trends over 24 years, projections for 2030, and their relationship with indigenous populations and gastroenterology services in Mexico.
METHODS: The study was based on mortality data from the Ministry of Health covering the 2000-2023 period. A total of 137,629 death records with ICD-10 codes C16.0-16.9 (gastric cancer) were extracted, including information on residence (state/municipality), sex, age (>20), and indigenous language-speaking status. Age-standardized mortality rates (ASMR)/100,000 inhabitants, linear regression trends, Joinpoint analysis projections, annual/average percentage changes (APC/AAPC), excess risk by municipality, and the annual gastroenterologist rate were estimated.
RESULTS: A notable decrease in ASMR was observed, from 11.0 in 2000 and 6.8 in 2023, with an AAPC of -2.1. Differences based on age and sex were documented: a moderate AAPC decrease among older women (≥50 years) of -1.8 and among older men of -2.1; however, a non-significant upward trend of 0.4 was observed in younger women (≤50 years), as well as a stable trend in men (0.03). Projections for 2030 suggest that gastric cancer mortality will continue to decline among older adults. The ASMR was higher in the central-southern-southeastern regions of the country and in populations with a high proportion of indigenous people who have limited access to specialized gastroenterological care.
CONCLUSION: Gastric cancer mortality trend was age-dependent, declining in older adults but rising among young people. Significant regional disparities persist, underscoring the need for targeted interventions and equitable access to specialized care.
