摘要: Triple negative breast cancers (TNBCs) are defined as tumors that do not express the estrogen receptor (ER), progesterone (PR) and HER2 isoform of epidermal growth factor (EGFR)(Foulkes et al., 2010). They account for approximately 10-17% all (Reis-Filho & Tutt, 2008). Clinically, they more prevalent among young African African-American women TNBCs poorly differentiated, highly malignant, aggressive have a poor outcome (Chen Russo, 2009). also characterized by early recurrence high rate visceral metastasis (Conte Guarneri, Moreover, peak risk occurs within three years diagnosis mortality rates increased five after (Kwan The molecular changes associated with been various immunohistochemistry gene expression profiling studies.
