BackgroundGliomas are the most common type of primary central nervous system tumor for both children and adults. However, the influence of racial/ethnic disparities on the survival of children with gliomas has not been fully evaluated yet.MethodsBaseline characteristics of patients, including sex, year of diagnosis, surgery, grade, radiation, histology, and races, were collected. Univariate and multivariate analyses for overall survival (OS) were performed using Cox proportional hazards regression model. Survival curves were plotted using Kaplan-Meier methods.ResultsA total of 4400 childhood patients were enrolled, including 2516 non-Hispanic whites (NHWs), 1050 Hispanic whites (HWs), 519 blacks, 282 Asians or Pacific Islanders (APIs), and 33 American Indian/Alaska Natives. NHWs had the longest overall survival (OS), whereas blacks had the shortest OS (P = 0.003). Stratified by histologic type, OS of children with astrocytoma was better among NHWs and HWs than among blacks and APIs (P = 0.004). OS of children with ependymoma was better among NHWs and APIs than among HWs and blacks (P = 0.008). However, no significant difference was observed in OS for children with medulloblastoma (P = 0.854).ConclusionsSurvival outcomes varied significantly by race/ethnicity among childhood gliomas. Better management of childhood gliomas is warranted to close the survival gap between race/ethnicity.Copyright © 2020 Elsevier Inc. All rights reserved.
