Triple negative breast cancer: breast cancer research in evolution.

A 2011 Pubmed search on the terms “breast cancer” and “triple negative” identified 932 articles, thus interest in this topic since the classification of triple negative/basal-like breast cancer has exploded and a number of recent informative reviews have been published [1–3]. We envision this special edition of Breast Disease focused on triple negative breast cancer (TNBC) as a “go-to” handbook accessible to clinical, translational and laboratory researchers in designing (and interpreting) studies of triple negative breast cancer. This issue contains in-depth reviews of multiple aspects of TNBC from triple negative cell lines to current clinical trials. We, the editors, would like to thank the authors for their excellent contributions and highlight a number of over arching issues.
