Abstract: | Background: Breast cancer mortality is significantly higher among black patients compared to white patients. Black women are reportedly
at increased risk for early-onset breast cancer. Our goal was to evaluate stage distribution relative to age among black and
white breast cancer patients in an institution with a relatively high minority patient population.
Methods: We evaluated 425 patients diagnosed with breast cancer between 1990 and 1994: 56% white, 34% black, the remainder were other
ethnicities. Patients were stratified by age: under 50 years versus 50 and older. Socioeconomic status was estimated by utilization
of medical care in the private-practice setting versus the public clinic.
Results: Significantly more black patients were younger at diagnosis compared to white patients (32% vs. 20%; p=0.008). There was
a significantly more advanced stage distribution among the younger black patients, but not among the older black patients.
Most of the black and white patients received private-practice care.
Conclusions: These age-related differences in breast cancer stage distribution between black and white patients (which appeared independent
of socioeconomic status) indicate that more aggressive screening and public education progams directed toward younger black
women is warranted, and they lend support to the possibility of ethnicity-related variation in primary tumor biology. |
