Background: Triple-negative breast cancers (TNBC) are the tumors lacking expression of estrogen receptors, progesterone receptors, and human epidermal growth factor 2. The highest level of androgen receptors (AR) expression belongs to the Luminal androgen receptor subtype. AR is expressed in 70 to 90% of primary breast cancers. The biological role of AR in breast cancer continues to emerge. The overexpression of epidermal growth factor receptor (EGFR) has been previously studied in TNBC, where it was found to be associated with poor prognosis. In the evaluation of neovascularization, CD105 (endoglin) was found to be superior to CD34 and CD31 owing to its greater affinity for endothelial cells in tumor-related angiogenic tissue. We conducted...
