Racial and ethnic disparities in survival of children with brain and central nervous tumors in the United States

Research output: Contribution to journalArticlepeer-review

Abstract

Background: Despite improvements in overall survival for pediatric cancers, treatment disparities remain for racial/ethnic minorities compared to non-Hispanic Whites; however, the impact of race on treatment outcomes for pediatric brain and central nervous system (CNS) tumors in the United States is not well known. Methods: We included 8713 children aged 0-19 years with newly diagnosed primary brain and CNS tumors between 2000 and 2015 from the Census Tract-level SES and Rurality Database developed by Surveillance, Epidemiology, and End Results (SEER) Program. We used chi-square tests to assess differences in sociodemographic, cancer, and treatment characteristics by race/ethnicity and Kaplan-Meier curves and Cox proportional hazards models to examine differences in 10-year survival, adjusting for these characteristics. Results: Among 8713 patients, 56.75% were non-Hispanic White, 9.59% non-Hispanic Black, 25.46% Hispanic, and 8.19% from “other” racial/ethnic groups. Median unadjusted survival for all pediatric brain tumors was 53 months, but varied significantly by race/ethnicity with a median survival of 62 months for non-Hispanic Whites, 41 months for non-Hispanic Blacks, and 40 months for Hispanic and other. Multivariable analyses demonstrated minority racial groups still had significantly higher hazard of death than non-Hispanic Whites; Hispanic (adjusted hazard ratio [aHR] 1.25 [1.18-1.31]); non-Hispanic Black (aHR 1.12 [1.04-1.21]); other (aHR 1.22 [1.12-1.32]). Results were consistent when stratified by tumor histology. Conclusion: We identified disparities in survival among racial/ethnic minorities with pediatric brain and CNS tumors, with Hispanic patients having the highest risk of mortality. Eliminating these disparities requires commitment toward promoting heath equity and personalized cancer treatment.
