Racial differences in long-term adjuvant endocrine therapy adherence and mortality among Medicaid-insured breast cancer patients in Texas: Findings from TCR-Medicaid linked dataBMC Cancer, 18
Key PointsQuestionAre there racial and ethnic disparities in the association of Medicaid expansion with survival among patients with de novo stage IV breast cancer? FindingsIn this cross-sectional study of 9322 patients with de novo stage IV breast cancer, Medicaid expansion was associated with improved survival and decreased 2-year mortality disparity in the postexpansion period compared with the preexpansion period. Survival differences observed between patients of racial and ethnic minority groups and White patients in the preexpansion period were no longer present in the postexpansion period. MeaningThese results suggest that Medicaid expansion was associated with a decrease in the racial and ethnic disparities in mortality among patients diagnosed as having de novo stage IV breast cancer, highlighting the importance of policies aimed at increasing equity and access to health care.
