Detailed Description
Breast Cancer )BC) is the most Common malignancy in women in 2020, there were 2.3 million women diagnosed with breast cancer and 685.000 deaths globally. Breast cancer rates are 88% higher in developed countries compared to developing countries .
TNBC represents accounts for approximately 24% of all breast cancer in 2020 .While in Egypt it accounts for 11.05% according to Egyptian national BC (5). By gene expression profiling ,4 subtypes of TNBC emerged : luminal androgen receptor (LAR), mesenchymal stem-like (MSL), immunomodulatory (IM), basal-like (BL1 and BL2) . Most of cases are advanced with median survival about 14 months . Brain and visceral organs represent common sites of distant metastasis . So it is considered the worst prognosis . In addition , chemotherapy is only option in treatment with no available targeted options for decades. Now we have Immunotherapy (IO ) and PARP inhibitors in neoadjuvant (NAT) and metastatic setting For example : Key note 355 which add Pembrolizumab in NAT which lead to marked improvement in pathological complete response ( PCR ) And in high risk patient and have marked results in disease and event free survival(8) .Poly (ADP-ribase) poly merase -1 (PARP-1) inhibitors appear to particularly effective in BRCA 1/2 mutation carries (9) .As reviewed by rodleret al. emerging data suggest that BRCA 1/2 carriers with TNBC disease may respond favorably to cisplatin therapy .
