Previous studies documented racial/ethnic and socioeconomic disparities in survival after Hodgkin lymphoma (HL) among adolescents and young adults (AYAs), but did not consider the influence of combined-modality treatment and health insurance.
Data for 9,353 AYA patients aged 15–39 when diagnosed with HL during 1988–2011 were obtained from the California Cancer Registry. Using multivariate Cox proportional hazards regression, we examined the impact of socio-demographic characteristics (race/ethnicity, neighborhood socioeconomic status (SES), and health insurance), initial combined-modality treatment, and subsequent cancers on survival.
Over the 24-year study period, we observed improvements in HL-specific survival by diagnostic period and differences in survival by race/ethnicity, neighborhood SES and health insurance for a subset of more recently diagnosed patients (2001–2011). In multivariable analyses, HL-specific survival was worse for Blacks than Whites with early-stage (Hazard Ratio (HR): 1.68; 95% Confidence Interval (CI): 1.14, 2.49) and late-stage disease (HR: 1.68; 95% CI: 1.17, 2.41) and for Hispanics than Whites with late-stage disease (HR: 1.58; 95% CI: 1.22, 2.04). AYAs diagnosed with early-stage disease experienced worse survival if they also resided in lower SES neighborhoods (HR: 2.06; 95% CI: 1.59, 2.68). Furthermore, more recently diagnosed AYAs with public health insurance or who were uninsured experienced worse HL-specific survival (HR: 2.08; 95% CI: 1.52, 2.84).
Our findings identify several subgroups of HL patients at higher risk for HL mortality.
Identifying and reducing barriers to recommended treatment and surveillance in these AYAs at much higher risk of mortality is essential to ameliorating these survival disparities.
