Abstract: Triple negative breast cancer represents multiple genomic and transcriptomic heterogeneities.
Genetic and epigenetic changes emerging in TNBC help it in acquiring resistance against
immunological response. Distant metastasis, lack of clinically targeted therapies and prognostic
markers make it the most aggressive form of breast cancer. In this review, we showed that driver alterations
in targeted genes AR, ERR, TIL, TAM, miRNA, mTOR and immunosuppressive cytokines
are predominantly involved in complicating TNBC by inducing cell proliferation, invasion
and metastasis, and by inhibiting apoptosis. The role of node status, cathepsin-D, Ki-67 index,
CD3+TIL, BRCA1 promoter methylation value and p53 as an efficient prognostic factor have also
been studied to predict the disease free and overall survival rate in TNBC patients. The present review
article is an attempt to gain an insight with a new vision on the etiology of TNBC, its treatment
strategies and prognostic marker to identify the outcome of standard therapies and to re-design
future treatment strategies to provide maximum benefit to patients.
