Breast cancer in black women.
Moormeier J.
University of Missouri-Kansas City School of Medicine, Kansas City, USA.
PURPOSE: To review the current knowledge about breast
cancer in black women--including epidemiology, risk factors, screening
practices, pathology, clinical manifestations, treatment, and outcome--with
emphasis on issues that might explain why the survival rate in this population
of women is lower than that in white women.
DATA SOURCES: The MEDLINE database from 1966 to 1995
and the bibliographies of all related articles.
STUDY SELECTION: Review articles and clinical studies
related to all aspects of breast cancer in black women.
DATA SYNTHESIS: The incidence of breast cancer is lower
in black women (95.8 cases per 100 000 women) than in white women (112.7
cases per 100 000 women). Differences in reproductive factors may partially
explain the lower risk for breast cancer among black women in the United
States. Breast tumors in black women are consistently diagnosed at a more
advanced stage of disease: Forty-two percent of black women present with
cancer confined to the breast compared with 53% of white women. In addition,
the cancers of black women tend to be more poorly differentiated and are
less likely to be estrogen receptor positive. Treatment of breast cancer
in black women appears to be similar to that in white women, but little
is known about systemic therapy choices and efficacy. Overall, despite
their lower risk for breast cancer, black women have a mortality rate
from breast cancer similar to that of white women because they have a
lower 5-year disease-specific survival rate (64% in black women compared
with 80% in white women).
CONCLUSIONS: The discrepancy in survival rate between
black and white women exists because black women have tumors that are
more advanced at the time of diagnosis, because tumor biology in black
women is different from that in white women (in particular, black women
have a higher frequency of poorly differentiated tumors and a lower frequency
of hormone receptor-positive tumors), and because of confounding comorbid
conditions and socioeconomic factors. Current efforts to improve survival
rates in black women with breast cancer should focus on community education,
screening efforts, and early detection. As more information is gained
about breast cancer treatment in black women, this may also be an important
area for intervention.
