In the United States, breast cancer survival is worse among African-American women compared with white women.
This difference in survival is likely due to several factors, including tumor biology and/or access to care.
In this analysis, we evaluated the effects of sociodemographic and clinical variables on differences in breast cancer survival among African-American and white women.
The study population included 10,502 women (82% white, 18% African-American), diagnosed between 1988 and 1992 and identified through the Metropolitan Detroit Cancer Surveillance System, a member of the Surveillance, Epidemiology and End-Results (SEER) Program.
Cox proportional hazards regression was used to estimate the relative risk of death comparing African-American women with white women after controlling for variables believed to influence survival.
The mean age at diagnosis was 61 years and average length of follow-up was 34 months (range, 1-78 months).
African-American women were more likely to present with regional or distant disease (45%) than were white women (37%). Although white women had better survival than African-American women during the first 4 years postdiagnosis (P<0.0001), there were no significant differences in survival by race for women who lived longer than 4 years (P=0.64).
There was a significant interaction between age and race.
The unadjusted relative risk of dying for African-American women compared with white women wa...
