INTRODUCTION • Triple-negative breast cancer (TNBC) represents 10%–20% of invasive breast cancers1 and has a very poor prognosis.2 There is a particular unmet need in TNBC, with a lack of clinically established targeted therapies3; chemotherapy is the only option for metastatic TNBC.4 • To facilitate access to new treatments, it is increasingly important to understand payer evidence needs in ad...

BACKGROUND Triple-negative breast cancer (TNBC) has a poor prognosis because of frequent recurrence. Androgen receptor (AR) is involved in the pathogenesis of breast cancer, but its role is not clearly defined. The aim of this study was to explore the expression of AR and its relationship with clinicopathologic features in TNBC. METHODS This study investigated 1036 cases of sporadic invasive ...

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...

Our preliminary data show that erlotinib inhibits Triple-negative breast cancer (TNBC) in a xenograft model. However, inhibition of metastasis by erlotinib is accompanied by nonspecific effects because erlotinib can inhibit other kinases; thus, more direct targets that regulate TNBC metastasis need to be identified to improve its therapeutic efficacy.

Triple-negative breast cancers constitute about 15% of all cases, but despite their higher response to neoadjuvant chemotherapy, the tumors are very aggressive and associated with a poor prognosis as well as a higher risk of early recurrence. This study was retrospectively performed on 101 patients with stage II and III invasive breast cancer who received 6-8 cycles of neo-adjuvant chemotherapy...

Triple-negative breast cancers, which lack estrogen receptor, progesterone receptor, and HER2/neu overexpression, account for approximately 15% of breast cancers, but occur more commonly in African Americans. The poor survival outcomes seen with triple-negative breast cancers patients are, in part, due to a lack of therapeutic targets. Epidermal growth factor receptor (EGFR) is overexpressed in...

INTRODUCTION MicroRNAs are small, non coding regulatory molecules containing approximately 21 to 25 nucleotides. They function as controllers of expression at post transcriptional levels of most human protein-coding genes and play an essential role in cell signaling pathways. The objective of the present study is to evaluate the expression profile of the following micro-RNAs: miR-10b, miR-17, m...

BACKGROUND Hereditary triple-negative breast cancer patients have better recurrence-free survival than triple-negative sporadic ones. High expression of some of the miRNAs is related to worse overall and disease-free survival of triple-negative breast cancer patients. The attempt to associate expression level of some miRNA in triple-negative hereditary and sporadic breast cancers to disease spe...

Breast cancer has been redefined into three clinically relevant subclasses: (i) estrogen/progesterone receptor positive (ER+/PR+), (ii) HER2/ERRB2 positive, and (iii) those lacking expression of all three markers (triple negative or basal-like). While targeted therapies for ER+/PR+ and HER2+ tumors have revolutionized patient treatment and increased lifespan, an urgent need exists for identifyi...

Take home messages The majority of basal-like breast cancers have a triple negative phenotype and the vast majority of triple negative cancers display a basal-like transcriptome, however the two are not synonymous. Basal-like and triple negative breast cancers comprise a heterogeneous group of diseases, which are characterised by a constellation of morphological features. Not all basal-like and...
