Beyer KMM, Zhou Y, Laud PW, et al. - Researchers aimed at determining the correlation between contemporary redlining (mortgage lending bias on the basis of property location) and survival among older women with breast cancer in the United States. They linked a redlining index utilizing Home Mortgage Disclosure Act data (2007-2013) by census tract with a SEER-Medicare cohort of 27,516 women (aged 66-90 years) with an initial diagnosis of stage I-IV breast cancer in 2007-2009 and follow-up through 2015. Overall, there were 34% of non-Hispanic White, 57% of Hispanic, and 79% of non-Hispanic Black individuals who resided in redlined tracts. Poorer breast cancer survival was recorded in correlation with contemporary redlining. The pronounced effect, even among women with health insurance (Medicare) and no comorbid conditions, emphasizes the impact of this bias. The immensity of this neighborhood level effect demands an increased focus on upstream determinants of health to support comprehensive patient care. The housing sector actively indicates structural racism and economic disinvestment and is suggested to be an actionable policy target to reduce adverse upstream health determinants for the benefit of patients with cancer.
