The Effect of Insurance and Race on Breast Cancer Tumor Biology and Short-Term Outcomes

Journal Article

To determine whether low-income status as demonstrated by insurance type has any association with aggressive tumor biology and breast cancer outcomes. Retrospective review of 535 women with new diagnosis of breast cancer from January 2009 to March 2013 was performed. There was no significant association between race and stage at diagnosis. Women with Medicaid/Charity coverage were diagnosed at more advanced stages, more likely to have triple-negative breast cancer (TNBC), and had longer time to treatment. Rate of TNBC was higher in black women and younger patients. There was no significant difference in breast cancer recurrence or survival by race, insurance type, age, or tumor biology. In multivariable analysis, only black race (P = 0.003) and Medicaid/Charity Insurance (P = 0.0008) were the most significant predictors of TNBC. Presentation of aggressive tumor biology and advanced stage is strongly associated with socio-economic factors as reflected by Medicaid funding and lack of insurance.
