BACKGROUND: Survival after breast carcinoma diagnosis is significantly worse among African American women for reasons unknown. The purpose of this study was to update reports on the National Surveillance, Epidemiology, and End Results Program and to examine the effect of race on breast carcinoma survival. METHODS: Subjects were 135,424 women diagnosed with primary breast carcinoma between 1988-1995. Patient age, tumor stage at the time of diagnosis, hormone receptor status, tumor histology, menopausal status, and survival were compared by race category. RESULTS: African American women diagnosed with breast carcinoma (n = 11,159) had a significantly increased risk of death from breast carcinoma and from all cancers compared with white women (n = 124,265), independent of the effects of other predictor variables. African American women were significantly younger at the time of diagnosis, with approximately 33% of the population age </= 50 years, compared with slightly <25% of the white women belonging to that younger age group. African American women were significantly more likely to present with advanced stages of breast carcinoma and, within each stage category, had significantly poorer survival compared with white women. African American women were significantly less likely to have tumors positive for estrogen or progesterone receptors, as well as histologically confirmed lobular and tubular carcinomas, whereas they were more likely to have inflammatory, medullary, and papill...
