Black and Asian women received significantly higher mean heart doses than white women in a Michigan study.
The intersection of disease biology with certain social determinants of health can lead to inferior outcomes, but there are other factors that influence disparities in care and outcome. To understand mediators of racial disparities among women with early-stage breast cancer receiving adjuvant whole-breast radiation therapy (WBRT), researchers obtained RT dosimetry data from the Michigan Radiation Oncology Quality Consortium (MROQC) database.
Mean heart dose (MHD) was compared for Asian, Black, and white women who were treated with WBRT at 25 institutions between 2012 and 2014. Of 8750 patients in the analysis, 2% were Asian, 18% Black, and 80% white. Black race was independently associated with higher MHD for women with left-sided cancers re…
