Zusammenfassung: | Background
Although pediatric cancer mortality and survival have improved in the United States over the past 40 years, differences exist by age, race/ethnicity, cancer site, and economic status. To assess progress, this study examined recent mortality and survival data for individuals younger than 20 years.
Methods
Age‐adjusted death rates were calculated with the National Vital Statistics System for 2002‐2016. Annual percent changes (APCs) and average annual percent changes (AAPCs) were calculated with joinpoint regression. Five‐year relative survival was calculated on the basis of National Program of Cancer Registries data for 2001‐2015. Death rates and survival were estimated overall and by sex, 5‐year age group, race/ethnicity, cancer type, and county‐based economic markers.
Results
Death rates decreased during 2002‐2016 (AAPC, –1.5), with steeper declines during 2002‐2009 (APC, –2.6), and then plateaued (APC, –0.4). Leukemia and brain cancer were the most common causes of death from pediatric cancer, and brain cancer surpassed leukemia in 2011. Death rates decreased for leukemia and lymphoma but were unchanged for brain, bone, and soft‐tissue cancers. From 2001‐2007 to 2008‐2015, survival improved from 82.0% to 85.1%. Survival was highest in both periods among females, those aged 15 to 19 years, non‐Hispanic Whites, and those in counties in the top 25% by economic status. Survival improved for leukemias, lymphomas, and brain cancers but plateaued for bone and soft‐tissue cancers.
Conclusions
Although overall death rates have decreased and survival has increased, differences persist by sex, age, race/ethnicity, cancer type, and economic status. Improvements in pediatric cancer outcomes may depend on improving therapies, access to care, and supportive and long‐term care.
Death rates of pediatric cancer decreased during 2002‐2016, with steeper declines during 2002‐2009, and then rates plateaued. Leukemia and brain cancer were the most common causes of death from pediatric cancer, and brain cancer surpassed leukemia in 2011. |
