Regional disability-adjusted life years (DALYs) and mortality rates in gastric cancer among elderly (70+ years) from 1990-2021: A global burden of disease study.

Abstract

e16076 Background: Gastric cancer is the fourth leading cause of global cancer deaths. Despite declining incidence and mortality, it remains a significant contributor to the global disease burden. This study analyzes regional gastric cancer DALYs and mortality trends from 1990-2021 using the GBD database. Methods: The regional DALYs and mortality rates per 100,000 individuals aged 70+ from GBD 2021 were analyzed, with trends from 1990 to 2021 evaluated using AAPC, and statistical significance assessed by p-values. Results: In 2021, the greatest Age-standardized DALYs rates were recorded in Andean Latin America, with 3068.04 per 100,000; the lowest was found in High-income North America with 386.08 per 100,000. The most significant increase of DALYs rate from 1990 to 2021 was in Southern Sub-Saharan Africa, (AAPC = -0.3068%; 95% CI: -0.3852 to -0.2234; p < 0.000001), while in Western Europe, the largest decline was noted (AAPC = -2.9999%; 95% CI: -3.0164 to -2.9841; p < 0.000001). Andean Latin America was the region with the highest Age-standardized mortality rates (ASMRs) in 2021, at 207.58 per 100,000 while High-income North America had the lowest at 27.18 per 100,000. In Western Sub-Saharan Africa, the ASMRs were rising with an AAPC of -0.2601% (95% CI: -0.2872 to -0.2368; p < 0.000001), while Western Europe had the highest decline with an AAPC of -2.7658% (95% CI: -2.7895 to -2.7471; p < 0.000001). Conclusions: The global burden of diseases from 1990 to 2021 is regional in nature. In 2021, DALYs and mortality were predominantly high in Andean Latin America and East Asia and notably low in High-income North America. DALYs have risen across Southern Sub-Saharan Africa over three decades, and mortality increased over Western Sub-Saharan Africa, while both declined sharply in Western Europe. These trends underscore the importance of regionalized health solutions. DALY per 100,000.
