Marc A. Emerson, Ph.D., from the University of North Carolina at Chapel Hill, and colleagues evaluated disparities in time to treatment and treatment duration by race and age among 2,841 patients with stage I to III disease participating in the Carolina Breast Cancer Study.
The researchers found that 32 percent of younger Black women were in the highest quartile of treatment duration versus 22 percent of younger White women. There was a higher frequency of delayed treatment seen among Black women (relative frequency difference, 5.5 percent) as well as prolonged treatment duration (relative frequency difference, 8.8 percent). There was a significant association between socioeconomic status (SES) and treatment delay among White women (relative frequency difference, 3.5 percent), but treatment delay was high at all levels of SES for Black women (e.g., 11.7 percent in high-SES Black women versus 10.6 and 6.7 percent among low- and high-SES White women, respectively). Among Black women, neither SES nor access to care classes were significantly associated with delayed initiation.
“Even among women with low socioeconomic status, we still saw fewer delays among White women, underscoring the disparate experience of Black women, who appear to experience unique barriers,” Emerson said in a statement.
