Objectives:
Triple-negative breast cancer is regarded as an aggressive disease that affects a young patient population and for which effective targeted therapy is not yet available.
Methods:
Intense efforts have been made to gain a better understanding of this heterogeneous group of tumors from the histologic to the genomic and molecular levels.
Results:
Progress has been made, including the ability to subtype these tumors and the discovery of biomarkers toward which current therapeutic efforts are focused. Many novel targets under exploration have the potential to affect the clinical course of this disease.
Conclusions:
This article reviews the current concepts regarding the clinicopathologic features of triple-negative breast carcinoma, its histologic subtypes, molecular classification, the prognostic and therapeutic potential of biomarkers, and emerging targeted therapies.
Insights
Triple-negative breast cancer (TNBC) is aggressive with limited targeted therapies. Research is advancing understanding of TNBC subtypes and biomarkers for new treatments.
Area of Science:
- Oncology
- Genomics
- Molecular Biology
Background:
- Triple-negative breast cancer (TNBC) is an aggressive cancer subtype.
- TNBC disproportionately affects younger patients.
- Effective targeted therapies for TNBC are currently limited.
Purpose of the Study:
- To review current concepts in triple-negative breast carcinoma.
- To discuss clinicopathologic features and histologic subtypes.
- To explore molecular classification and biomarker potential.
Main Methods:
- Review of existing literature on TNBC.
- Analysis of histologic and molecular subtyping data.
- Evaluation of biomarker prognostic and therapeutic potential.
Main Results:
- Progress in subtyping TNBC tumors has been achieved.
- Biomarkers have been discovered for targeted therapeutic efforts.
- Novel targets are under exploration for TNBC treatment.
Conclusions:
- Understanding TNBC clinicopathologic features is crucial.
- Histologic and molecular subtypes impact prognosis and treatment.
- Emerging targeted therapies show promise for TNBC management.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
