Highlights
- •Black women experience treatment delays for non-metastatic breast cancer more frequently than white women.
- •Women in metro areas experience treatment delay more than women in rural areas.
- •Lower education and higher income were associated with treatment delay.
- •Improving access to timely treatment may lessen sociodemographic breast cancer disparities.
Abstract
Background
Although evidence suggests worse breast cancer-specific survival associated with treatment
delay beyond 90 days, little is known regarding the sociodemographic predictors of
delays in cancer-directed surgery among young women with breast cancer. This is particularly
notable, given that 5–10% of new diagnoses occur in younger women aged <40 years,
commonly with more aggressive features than in older women.
Methods
We used the National Cancer Database (2004–2017) to assess sociodemographic disparities
in delay of upfront surgery beyond 90 days among young women with non-metastatic breast
cancer, using multivariable logistic regression and predictive marginal modeling.
Results
Black women experienced treatment delays more frequently than white women (aOR: 1.93
[95% CI: 1.76–2.11], p < 0.001). Adjusted rates of treatment delay were 4.91% [95%
CI: 4.51%–5.30%] and 2.60% [95% CI: 2.47%–2.74%] for Black and white women, respectively,
and 2.97% [95% CI: 2.83%–3.12%], 2.36% [95% CI: 2.03%–2.68%], and 1.18% [95% CI: 0.54%–1.81%]
for women from metro, urban, and rural areas, respectively.
Conclusion
These results suggest that improving access to timely treatment may be leveraged as
a means through which to lessen the breast cancer disparities experienced by Black
women.
