Although African American women have a higher incidence of triple-negative breast cancer than white women, a study conducted at Washington University suggests that survival with triple-negative breast cancer may not vary by race. These results were published in Breast Cancer Research and Treatment.
Studies have consistently demonstrated that African American women have higher rates of triple-negative breast cancer than white women. Results have been less consistent, however, on the question of whether survival with triple-negative breast cancer also varies by race.
To explore this question, researchers conducted a study among 490 women with triple-negative breast cancer who were treated at the Washington University Breast Oncology Clinic. Thirty percent of the women were African American.
- African American and white women were similar in terms of age at diagnosis, time from abnormal imaging to biopsy and from biopsy to surgery, receipt of neoadjuvant or adjuvant chemotherapy, and response to neoadjuvant chemotherapy.
- Disease-free and overall survival did not vary significantly by race.
The researchers conclude that in this single center, where African American and white women received similar treatment and follow-up, the presentation and outcome of triple-negative breast cancer did not vary significantly by race.
