Abstract

PURPOSE:

Childhood cancer survivors carry a high burden of treatment-related morbidity; however, race/ethnicity-specific risks of adverse outcomes are not well understood.

METHODS:

Data from the Childhood Cancer Survivor Study, a cohort of survivors of at least 5 years, were used to compare Hispanic (n = 750, 5.4%) and non-Hispanic black (NHB: n = 694, 5.0%) survivors to non-Hispanic white patients (NHW: n = 12,397, 89.6%) for late mortality, subsequent neoplasms, and chronic health conditions.

RESULTS:

NHBs and Hispanics reported lower socioeconomic status (SES) and higher prevalence of obesity, and NHBs reported higher prevalence of hypertension. NHBs had higher rate of all-cause mortality (relative rate [RR], 1.4; 95% CI, 1.1 to 1.9; P = .008), which was abrogated (RR, 1.0; 95% CI, 0.8 to 1.4; P = .9) after adjusting for SES. Nonmelanoma skin cancer was not observed among irradiated NHBs, and the risk was lower among Hispanic survivors (RR, 0.3; 95% CI, 0.1 to 0.7) compared with NHWs. Both NHBs and Hispanics demonstrated elevated risks for diabetes; these risks persisted after adjusting for SES and obesity (NHBs: RR, 2.8; 95% CI, 1.1 to 6.7; Hispanics: RR, 3.1; 95% CI, 1.5 to 6.4). NHBs were more likely to report cardiac conditions (RR, 1.8; 95% CI, 1.1 to 2.7), but the risk was attenuated after adjusting for cardiovascular risk factors. Therapeutic exposures did not affect racial/ethnic differences in mortality (all cause or cause specific), chronic health conditions, or subsequent neoplasms.

CONCLUSION:

By and large, NHB and Hispanic childhood cancer survivors experience a comparable burden of morbidity and mortality to their NHW counterparts. The few differences in risk were explained by the racial/ethnic differences in socioeconomic status and/or cardiovascular risk factors.
