Abstract
Background: Central nervous system (CNS) cancers are highly lethal and increasingly affect younger populations aged 20-49, posing significant challenges to global healthcare systems. Current research on early-onset CNS cancer trends is limited and outdated, with uncertain impacts from the COVID-19 pandemic. This study explores the epidemiology of early-onset CNS cancer and the pandemic's effects.
Methods: We analyzed incidence, mortality, and disability-adjusted life years (DALYs) rates for early-onset CNS cancer (age 20-49) from 2019 to 2021 using GBD 2021 data. The global data were categorized into five regions based on the Socio-Demographic Index (SDI), reflecting income, education, and fertility rates. Trends over the past 30 years were examined using estimated annual percentage change (EAPC), average annual percentage change (AAPC), and joinpoint analysis, with a focus on 2019-2021. The Bayesian age-period-cohort (BAPC) model predicted post-pandemic impacts on CNS cancer metrics.
Results: In 2021, global cases of early-onset CNS cancer rose to 50 201.7 (95% UI, 42 864.1-58 187.5), with deaths increasing to 25 023.1 (95% UI, 20 973.8-29 670.8) and DALYs reaching 1 483 019.4 (95% UI, 1 240 923.4-1 756 043.3). The incidence rate increased to 2.1 (95% UI, 1.8-2.5), while mortality rates remained stable at 1.1 (95% UI, 0.9-1.2), and DALY rates decreased to 62.6 (95% UI, 52.4-74.1). Over the past two decades, the incidence of early-onset CNS cancer has steadily increased, particularly in regions with a high SDI and in emerging economies. Although there was a decline in early-onset CNS cancer-related metrics during the pandemic, it is anticipated that global incidence rates will peak between 2035 and 2040.
Conclusion: This study provides a comprehensive overview of early-onset CNS cancer trends. Despite stable mortality rates, the increasing incidence suggests a growing global burden, with a delayed peak expected due to the pandemic. These findings highlight the need for preventive and control policies targeting early-onset CNS cancer.
期刊介绍：
The International Journal of Surgery (IJS) has a broad scope, encompassing all surgical specialties. Its primary objective is to facilitate the exchange of crucial ideas and lines of thought between and across these specialties.By doing so, the journal aims to counter the growing trend of increasing sub-specialization, which can result in "tunnel-vision" and the isolation of significant surgical advancements within specific specialties.
