Pediatric hodgkin lymphoma: disparities in survival by race

Abstract

The purpose of this study was to examine factors associated with disparities in overall survival (OS) by race in pediatric Hodgkin Lymphoma (HL) patients. We evaluated clinical features and survival among patients ≤21 years of age diagnosed with stage I–IV HL from 2004 to 2015 from the National Cancer DataBase (NCDB) using a multivariable Cox proportional hazards model. Among 11,546 patients with pediatric HL, 9285 patients met eligibility criteria. Black patients experienced a 5-year OS of 91.5% vs 95.9% in White patients (p < .0001). After adjusting for confounders, Black race was associated with a significantly decreased OS (HR = 1.50; 95% CI: 1.12–1.99; p < .01). In stratified analysis by ages ≤15 years, 16–18 years, and >18 years, Black race was associated with poorer OS among compared to Whites with rates of 95.4% vs 97.7%, 87.1% vs 96.1%, and 91.6% vs 94.6% respectively. Overall, Black pediatric HL patients had lower overall survival in this study.
