TNBC accounts for up to 20% of breast cancer cases and despite its heterogeneity, three receptors are commonly overexpressed, namely the EGFR1 (in up to 70% of TNBC cases), the epithelial cell adhesion molecule (EpCAM) and chondroitin sulfate proteoglycan 4 (CSPG4) [6,7]. The gene discussed is CSPG4; the disease is breast cancer.
