Scott LC, et al. - Researchers investigated how triple-negative breast cancers (TNBCs) are different from all other breast cancers with regard to age, race/ethnicity, and stage at diagnosis. For this purpose, they selected and analyzed 1,151,724 cases of breast cancer, including 8.4% cases with triple-negative phenotype, from the United States Cancer Statistics database. They found higher odds of diagnosis among non-Hispanic black women and Hispanic women vs non-Hispanic white women in unadjusted analyses. The highest odds of diagnosis were observed in women aged < 40 years vs women aged 50 to 64 years. In addition, higher odds of the diagnosis of TNBC were reported in relation to diagnosis at American Joint Committee on Cancer stage III and beyond.
