Triple-negative breast cancer (TNBC), which is defined by the lack of expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2), is the most fatal subtype of breast cancer and is associated with relatively poorer outcomes compared with other breast cancer subtypes [3,4,5,6]. This evidence concerns the gene ERBB2 and triple-negative breast carcinoma.
