Screening facility resources and aggressiveness of tumors were identified as being two major factors that explain racial/ethnic disparity among patients recently screened for symptomatic breast cancer, according to an article published online in the journal Cancer Epidemiology, Biomarkers & Prevention.
Participants in this study included patients recently diagnosed with breast cancer and analyzed regarding the probability of symptomatic awareness despite a recent screening mammogram (SADRS). Patients who did not report a recent prior screening were not included in the study analyses.
Results showed SADRS was more common among nH
P=0.0004). Furthermore, an association was identified between SADRS and estrogen and progesterone receptor (ER/PR) negative status and higher grade disease.
SADRS was less likely to be reported at centers with dedicated radiologists and site that were labeled as breast imaging centers of excellence.
Two-thirds of the racial/ethnic disparity in SADRS was explained by tumor biology and facility factors (proportion mediated=70%, P=0.02).
