Abstract
Introduction: Updated estimates of the current and future burden of non-Hodgkin lymphoma (NHL) are critical for evaluating global cancer control efforts and addressing disparities in disease impact across regions.
Material and methods: We assessed the 2022 global NHL burden and projected trends to 2045 across 185 countries using population-based cancer registry data from the Cancer Incidence in Five Continents (CI5) database and GLOBOCAN 2022 estimates. Trends in age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) from 1990 to 2017/2020 were analyzed in selected regions to contextualize findings.
Results: In 2022, an estimated 553,389 new NHL cases (ASIR 5.6/100,000) and 250,679 deaths (ASMR 2.4/100,000) occurred globally. The highest case numbers were observed at ages 65-69, with ASIR peaking at 85+ and men consistently showing higher rates. High-HDI regions, such as Northern America (ASIR 12.49) and Australia/New Zealand (ASIR 12.05), reported elevated incidence compared to low-HDI regions like South-Central Asia (ASIR 2.79). East Asia, led by China (14.6% of cases), had the largest case volume. ASIR strongly correlated with HDI (r = 0.655, p = 3.21E-22), while ASMR showed no significant correlation (r = 0.002, p = 0.982). By 2045, NHL cases are projected to increase to 889,841 and deaths to 433,254, with low-HDI regions experiencing the steepest rises.
Conclusions: Our findings reveal pronounced global disparities in NHL burden, with high-HDI regions benefiting from treatment advances, while low-HDI areas face escalating challenges by 2045. Addressing aging-driven incidence, expanding diagnostic capacity in resource-limited settings, and strengthening prevention efforts are imperative to tackle these inequities and curb the projected burden.
期刊介绍：
Archives of Medical Science (AMS) publishes high quality original articles and reviews of recognized scientists that deal with all scientific medicine. AMS opens the possibilities for young, capable scientists. The journal would like to give them a chance to have a publication following matter-of-fact, professional review by outstanding, famous medical scientists. Thanks to that they will have an opportunity to present their study results and/or receive useful advice about the mistakes they have made so far.
The second equally important aim is a presentation of review manuscripts of recognized scientists about the educational capacity, in order that young scientists, often at the beginning of their scientific carrier, could constantly deepen their medical knowledge and be up-to-date with current guidelines and trends in world-wide medicine. The fact that our educational articles are written by world-famous scientists determines their innovation and the highest quality.
