Trends in non-Hodgkin lymphoma mortality: global, regional, and national insights from 1990 to 2021
1Department of Hematology, The Second Affiliated Hospital of Air Force Medical University, Xi'an, Shaanxi, China.
Background:
Non-Hodgkin Lymphoma (NHL) is a group of hematological cancers with significant global mortality. Despite advances in treatment, mortality disparities persist across age, sex, region, and socioeconomic status, underscoring the need for a deeper understanding of global trends.
Research Design And Methods:
Data from the Global Burden of Disease Study covering 204 countries between 1990 and 2021 were analyzed. The data were stratified by sex, age, and Socio-Demographic Index (SDI). Trends were assessed using the Estimated Annual Percentage Change (EAPC), and correlations with SDI were evaluated.
Results:
From 1990 to 2021, global NHL deaths increased from 146,657 to 267,061, and death rates rose from 2.75 to 3.38 per 100,000 (EAPC: 0.51). Males and individuals aged 75 and older had higher mortality rates. High-SDI regions, including High-income North America (8.49 per 100,000) and High-income Asia Pacific (9.60 per 100,000), had the highest rates. Middle-SDI regions showed the most significant increases, while low-SDI regions experienced declines. Japan had a sharp rise in mortality (EAPC: 3.03), while Ethiopia had a decline (EAPC: -2.09).
Conclusion:
NHL mortality increased globally from 1990 to 2021, with higher burdens in males and older adults. The fastest increases were observed in middle-SDI regions, reflecting healthcare disparities.
