According the collected literature, TNBC is one of breast cancer type can be found in women with breast cancer. It estimated about 170.000 of TNBC cases worldwide. The ER-/PR-/HER2- TNBC is the character for TNBC, and it has the poorest prognosis among other breast cancer. The risk factor of TNBC is gender, age, breastfeeding status, and special race such as African-American and Hispanic. Besides, the BRCA-1 mutation is related to TNBC. The treatment of TNBC is including surgery and radiotherapy, chemotherapy, and targeted therapy. The surgery, including BCS (Breast-conserving surgery) or called as lumpectomy and mastectomy; chemotherapy agent sensitive to TBNC, including alkylator agents, anthracyclines, taxanes, platinum-based chemotherapy, vinca alkaloids, and antimetabolites; as well targeted therapy such as PARP1 and PARP2 inhibitor, CDK (Cyclin-dependent kinase) inhibitor, p%3 inhibitor, CHK1 inhibitor, androgen antagonist, DNMT1 (DNA Methyltransferase 1) inhibitor, Anti-EGFR, PI3K/AKT/mTOR inhibitor, and anti-VEGF. These treatments are used both in early and metastatic stage of TNBC, alone or in combination.
