A Comparison of Breast Cancer Treatment Regimens by Demographic Characteristics
Abstract
The purpose of this study was to measure ethnic differences in treatment and survival between African American (AA) and European American (EA) women with breast cancer. This annual report presents results of the survival analysis. We abstracted data on cases of breast cancer diagnosed in members of an HMO in metropolitan Detroit between 1986-1996 (N=886) and followed these cases for survival through April 1997 (N=137 deaths). AA women were diagnosed at a later stage when compared with EA women. Five-year survival was 77% for AAs and 84% for EAs. The crude hazard for AAs relative to EAs was 1.6 (95% confidence interval (Cl) 1.1, 2.2). Adjusting only for stage of disease at diagnosis, the hazard ratio was 1.3 (95% CI 0.9, 1.9). Adjusting only for sociodemographics (age, marital status and income), the hazard ratio was 1.2 (95% CI 0.8, 1.9). After adjusting for sociodemographics and stage, the hazard ratio was 1.0 (95% CI 0.7, 1.5). We found no material racial differences in the surgical management of breast cancer. Among women with similar medical care access, we found ethnic differences in stage of breast cancer at diagnosis. Adjusting for this difference and for income, age and marital status, eliminates the effect of race on survival.
