Race and Cancer -
Previous CancerWeb issues (see also under pancreas cancer in this
issue) have generally stressed disparities in cancer rates based
on race, attributing much of the higher rate for some cancers
among the black US population to socioeconomic factors, or later
diagnosis and treatment. However, many studies in this area have
not included enough patients to give a really definitive answer,
while not all cancers may show a discrepancy in racial incidence.
The October, 1995 meeting of the American Society for Therapeutic
Radiology and Oncology in Miami Beach included a 40-year follow-
up study from the University of Chicago that included 1,277 white
and 481 black women who had mastectomies between 1927 and 1987.
About 40% of the women for both races were less than 50 years old
when diagnosed. The results clearly showed no difference between
the racial groups. Disease-free survival rates for early-stage
disease without positive lymph nodes were 83% for blacks and 78%
for whites. The corresponding figures for those women with
advanced disease were 18% and 17%.
