Racial and ethnic differences in survival of pediatric patients with brain and central nervous system cancer in the United States.

ABSTRACT: BACKGROUND:Brain and central nervous system (CNS) cancer is the leading cause of cancer death among children and adolescents in the United States. Data from earlier studies suggested racial and ethnic differences in survival among pediatric patients with brain tumor. This study examined racial/ethnic difference in survival using national data and considered the effects of demographic and clinical factors. METHODS:Using National Program of Cancer Registries data, 1-, 3-, and 5-year relative survival (cancer survival in the absence of other causes of death) was calculated for patients with brain and CNS cancer aged < 20 years diagnosed during 2001-2008 and followed up through 2013. Racial and ethnic differences in survival were measured by sex, age, economic status, stage, anatomic location, and histology. Adjusted racial and ethnic difference in 5-year cancer specific survival was estimated using multivariable Cox regression analysis. RESULTS:Using data from 11 302 patients, 5-year relative survival was 77.6% for non-Hispanic white patients, 69.8% for non-Hispanic black patients, and 72.9% for Hispanic patients. Differences in relative survival by race/ethnicity existed within all demographic groups. Based on multivariable analysis, non-Hispanic black patients had a higher risk of death at 5 years after diagnosis compared to non-Hispanic white patients (adjusted hazard ratio = 1.2, 95% confidence interval, 1.1-1.4). CONCLUSIONS:Pediatric brain and CNS cancer survival differed by race/ethnicity, with non-Hispanic black patients having a higher risk of death than non-Hispanic white patients. Future investigation of access to care, social and economic barriers, and host genetic factors might identify reasons for disparities in survival.

Project description:BackgroundRacial/ethnic disparities in the utilization of hematopoietic cell transplantation (HCT) have been reported for patients with hematologic malignancies, but population-based data are lacking for lymphoma patients. The objective of this study was to determine whether racial and ethnic disparities exist in the utilization of autologous HCT for lymphoma in the United States.MethodWe used Surveillance, Epidemiology, and End Results data linked to Medicare fee-for-service claims. We included Medicare beneficiaries aged 66+ years with Hodgkin or Non-Hodgkin lymphomas diagnosed between 2008 and 2015. The primary outcome was time-to-autologous HCT. We used Cox proportional hazards models to estimate racial/ethnic differences in utilization. Missing data were handled using multiple imputation with chained equations.ResultsWe included 40,605 individuals with lymphoma. A total of 452 autologous transplants were performed. In the unadjusted model, Non-Hispanic Black patients were 51% less likely to receive a transplant than Non-Hispanic White patients (95% CI, 0.26-0.96; p = 0.04). After adjusting for age at diagnosis and sex, Non-Hispanic Black patients were 61% less likely to receive a transplant (95% CI, 0.20-0.76; p = 0.01). However, observed differences attenuated and became non-significant after adjustment for socioeconomic factors (adjusted hazard ratio [aHR], 0.62; 95% CI, 0.32-1.21; p = 0.16) and disease-specific factors (aHR, 0.58; 95% CI, 0.30-1.12; p = 0.11), separately. In the fully adjusted model, we also did not observe a statistically significant association between Non-Hispanic Black race/ethnicity and receipt of transplant (aHR, 0.54; 95% CI, 0.28-1.05; p = 0.07).ConclusionIn this population-based cohort study of lymphoma patients, Non-Hispanic Black patients were less likely to receive autologous HCT compared to Non-Hispanic White patients, but this difference was partially explained by socioeconomic and disease-specific factors.
