Introduction Germline BRCA mutations (gBRCAm) are diagnosed in approximately 5% of unselected breast cancer patients. Olaparib is a new treatment option for patients with a gBRCAm who have metastatic HER2-negative breast cancer. Areas Covered Olaparib is an oral poly (ADP-ribose) polymerase inhibitor that has been shown in phase I-III clinical trials to have single-agent efficacy in breast cancer patients with gBRCAm. The recent phase III OlympiAD study demonstrated a statistically significant progression free survival benefit compared to the chemotherapy control arm, although an overall survival benefit has not been demonstrated...

PURPOSE: Therapeutic decisions in breast cancer patients crucially depend on the status of estrogen receptor, progesterone receptor and HER2, obtained by immunohistochemistry (IHC). These are known to be inaccurate sometimes, and we demonstrate how to use gene-expression to increase precision of receptor status. METHODS: We downloaded data from 3241 breast cancer patients out of 36 clinical studies. For each receptor, we modelled the mRNA expression of the receptor gene and a co-gene by logistic regression...

Background: Oncotype dx [odx (Genomic Health, Redwood City, CA, U.S.A.)] is an approved prognostic tool for women with node-negative, hormone receptor-positive, her2-negative breast cancer. Because of cost, optimal use of this test is crucial, especially in a publicly funded health care system. We evaluated adherence with our provincial guidelines for odx requests, the management of patients with an intermediate recurrence score (rs), and the cost impact of odx. Methods: This retrospective study included 201 consecutive patients with an odx request from two university institutions in Quebec between May 2012 and December 2014...

INTRODUCTION: Premenopausal women with hormone receptor positive (HR+) and human epidermal growth factor receptor-2-negative (HER2-) advanced breast cancer (aBC) often present with aggressive tumor types that lead to poor prognosis, high rates of recurrence, and mortality. Although clinical guidelines provide evidence-based recommendations for optimal treatment and monitoring, there is a dearth of information regarding treatment and monitoring patterns in clinical practice. In this study, we describe treatment and monitoring patterns among premenopausal women with HR+/HER2- aBC in real-world practice...

REVIEW
Roger K C Ngan
Hormone therapy, rather than chemotherapy, is recommended for hormone-receptor positive (HR+), human epidermal receptor 2 negative (HER2-) advanced or metastatic breast cancer (A/MBC) according to the European Society of Medical Oncology (ESMO), American Society of Clinical Oncology (ASCO) and National Comprehensive Cancer Network (NCCN) guidelines, unless in visceral crisis in which chemotherapy is indicated. Hormonal monotherapy of selective estrogen receptor modulator (SERM) or selective estrogen receptor down-regulator (SERD), aromatase inhibitor (AI), or their combination as doublets, used to be the mainstay options as first-line (1L) therapy for most patients...

Breast cancers (BCas) that lack expression of the estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) are referred to as triple negative breast cancers (TNBCs) and have the poorest clinical outcome. Once these aggressive tumors progress to distant organs, the median survival decreases to 12 months. With endocrine therapies being ineffective in this BCa subtype, highly toxic chemo- and radiation therapies are the only options. A better understanding of the functional role(s) of molecular targets contributing to TNBC progression could help in the design and development of new treatments that are more targeted with less toxicity...

In addition to amplification, point mutations of the human epidermal growth factor receptor 2 (HER2) gene (ERBB2) have been shown to activate the corresponding signaling pathway in breast cancer. The prevalence of ERBB2/HER2 mutation in bone metastasis of breast cancer and the associated phenotype are not known. In this study, bone metastases from breast cancer patients (n = 231) were analyzed for ERBB2/HER2 mutation. In 7 patients (3%; median age 70 years, range 50-83 years), gain-of-function mutations of ERBB2/HER2 were detected...

BACKGROUND: Upregulation of human epidermal growth factor receptor 3 (HER3) is a major mechanism of acquired resistance to therapies targeting its heterodimerization partners epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2), but also exposes HER3 as a target for immune attack. We generated an adenovirus encoding full length human HER3 (Ad-HER3) to serve as a cancer vaccine. Previously we reported the anti-tumor efficacy and function of the T cell response to this vaccine...

Metastatic breast cancer (MBC) is the leading cause of cancer-related morbidity and mortality among women worldwide. Endocrine therapy is the standard of care for the most common subtype of MBC, hormone-receptor positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) disease. Advances in treating this type of MBC have focused on improving the efficacy of endocrine therapy by adding agents that target specific molecular pathways of breast cancer cell growth and survival. The combination of the aromatase inhibitor exemestane and the mammalian target of rapamycin inhibitor, everolimus, more than doubled median progression-free survival compared with exemestane alone (7...
