摘要: Background: African-American women with breast cancer have poorer survival than European-American women. After adjustment for socioeconomic variables, differences diminish but do not disappear, possibly because of residual in health care access, biology, or behavior. This study compared and similar access. Methods: We measured who are served by a large medical group metropolitan Detroit maintenance organization where screening, diagnosis, treatment, follow-up based on standard practices mammography is covered benefit. abstracted data had been diagnosed from January 1986 through April 1996 (n = 886) followed these 1997 (137 deaths). Results : were at later stage Median was 50 months. Five-year 77% 84% The crude hazard ratio relative to 1.6 (95% confidence interval [CI] 1.1-2.2). Adjusting only stage, the 1.3 CI 0.9-1.9). sociodemographic factors (age, marital status, income), 1.2 0.8-1.9). adjusting age, income, 1.0 0.7-1.5). Conclusion: Among access since before their diagnoses, we found ethnic diagnosis. Adjustment this difference status resulted negligible effect race survival.
