Racial differences in survival of women with breast cancer.
Bain RP, Greenberg RS, Whitaker JP.
The hypothesis that white women with breast cancer survive longer than
black women with this disease was evaluated in a retrospective analysis
of a population-based prospective follow-up study. All female residents
of metropolitan Atlanta with a first diagnosis of primary breast cancer
between 1 January 1978 and 31 December 1982 were eligible for inclusion.
The study population of 2322 white and 536 black women was followed through
the end of calendar year 1983 to determine vital status. Univariate, multivariate
and excess death rate analyses were performed to evaluate race as a prognostic
factor. Overall, the cumulative percentage of survivors at 3 years was
83% among whites, compared with 71% among blacks. The racial difference
in survival was greatest among women with advanced disease, and a higher
proportion of black women with advanced disease did not receive surgery.
Even when the type of surgery and stage of disease were controlled, race
was a significant prognostic factor.
