Abstract
BACKGROUND: Racial disparities in breast cancer care have been linked to treatment delays. We explored whether receiving care at a comprehensive breast center could mitigate disparities in time to treatment. METHODS: Retrospective chart review identified breast cancer patients who underwent surgery from 2012 to 2018 at a comprehensive breast center. Time-to-treatment intervals were compared among self-identified racial and ethnic groups by negative binomial regression models. RESULTS: Overall, 2094 women met the inclusion criteria: 1242 (59%) White, 262 (13%) Black, 302 (14%) Hispanic, 105 (5%) Asian, and 183 (9%) other race or ethnicity. Black and Hispanic patients more often had Medicaid insurance, higher American Society of Anesthesiologists (ASA) scores, advanced-stage breast cancer, mastectomy, and additional imaging after breast center presentation (p < 0.05). After controlling for other variables, racial or ethnic minority groups had consistently longer intervals to treatment, with Black women experiencing the greatest disparity (incidence rate ratio 1.42). Time from initial comprehensive breast center visit to treatment was also significantly shorter in White patients versus non-White patients (p < 0.0001). Black race, Medicaid insurance/being uninsured, older age, earlier stage, higher ASA score, undergoing mastectomy, having reconstruction, and requiring additional pretreatment work-up were associated with a longer time from initial visit at the comprehensive breast center to treatment on multivariable analysis (p < 0.05). CONCLUSION: Racial or ethnic minority groups have significant delays in treatment even when receiving care at a comprehensive breast center. Influential factors include insurance delays and necessity of additional pretreatment work-up. Specific policies are needed to address system barriers in treatment access.
