Kehm RD, et al. - Researchers used population-based cancer survival data from the Surveillance, Epidemiology, and End Results 18 database and applied mediation methods to measure the role of socioeconomic status (SES) in racial/ethnic differences in childhood cancer survival. Data analysis was performed for black, white, and Hispanic children who had been diagnosed at the ages of 0 to 19 years in 2000-2011 (n = 31,866). They found that racial/ethnic childhood cancer survival disparities for several cancers were significantly mediated by SES. However, they noted differences in the proportion of the total race/ethnicity–survival association explained by SES between black-white and Hispanic-white comparisons for some cancers. This was indicative of mediation by other factors across groups.
