Breast cancer remains a common cancer diagnosed in women. Its treatment is currently determined by expression of
predictive and prognostic markers ER, PR and HER2. More than 50% of breast cancer are ER+/PR+/HER2- and have the
best prognosis, due to effective targeted hormonal therapies and a more indolent clinical course. The two HER2+ subtypes
represent approximately 20% of breast cancer and prior to targeted therapy, had some of the worst prognosis. The TNT (triple
negative tumor) defined as ER/PR/HER2 negative, comprise 10-30% of breast cancers. It has recently emerged as a highly
aggressive subtype arising in younger women, prevalent among some ethnic groups (African-American (AA) and Hispanics)
and with no available effective targeted therapy using unsupervised gene clustering TNTs may be further subcalssified (basal-
like, claudin low, p53 mutated BRCA1 associated etc.), mirroring the different histopathologic appearance, with a range of
prognoses and responses to treatment.
At molecular levels they show differential expression, by race, of basal cytokeratin, stem cells markers, claudins, growth
factors and proliferative genes. In AA women these tumors show signs of aggressivity: clinically are larger at presentation and
have a poor outcome; at molecular level they show higher proliferation activity and p53 expression. The high prevalence of
TNT, with their accompanying poor survival and unique protein expression patterns, among younger women and particularly
younger AA women suggests varying differences in gene-environment.
This difference between the TNTs in different ethnic groups is of interest in view of their different biologic behaviors,
indicating the need for personalized therapy.
