BACKGROUND: Several studies have suggested that primary tumor removal improved overall survival for patients with stage IV breast cancer. However, the survival benefit of local treatment remains controversial. The purpose of the present study was to determine whether surgical removal of the primary tumor provides survival benefits to patients with stage IV breast cancer. PATIENTS AND METHODS: We retrospectively reviewed the medical records of 155 patients with an initial diagnosis of stage IV breast cancer at Seoul National University Bundang Hospital from 2003 to 2014...

BACKGROUND: High triglycerides and low levels of high density lipoprotein (HDL)-cholesterol are observed to promote tumor growth. However, whether breast cancer heterogeneity may explain the contradictory influence of triglycerides and cholesterol observed on breast cancer prognosis remains unclear. METHODS: A population-based survival study among 464 breast cancer cases identified within the Tromsø study was conducted. Pre-diagnostic triglycerides, total-cholesterol and HDL-cholesterol were measured, and detailed clinical and histopathological data were obtained...

Androgen receptor (AR) expression is an emerging prognostic marker that has been observed in 25% to 75% of triple negative breast cancers (TNBCs) that lack estrogen receptor, progesterone receptor and HER2 overexpression. TNBCs are treated with AR-targeted therapies and standardized evaluation of AR expression may help guide patient management. Basal-like TNBCs are a subgroup of TNBCs defined by positive immunoreactivity for CK5/6 or EGFR that carry a worse prognosis. However, it's unclear whether basal-like TNBCs have a different rate of AR positivity or if AR expression is predictive of disease free survival in this patient group...

Fibroblast growth factor 18 (FGF18) increases cell motility and invasion in colon tumors, and is linked with ovarian and lung tumors. Furthermore, the increased expression of FGF18 mRNA and protein has been associated with poor overall survival in cancer patients. However, its function has not been investigated in breast cancer. In the present study, we demonstrated that FGF18 promoted cell growth and metastasis in vitro and stimulated tumor growth in xenograft models in vivo. FGF18 mediated the proliferation of MDA‑MB‑231 cells via the ERK/c‑Myc signaling pathway and induced epithelial‑to‑mesenchymal transition (EMT) factors to promote cancer migration and invasion...

Trop2 is considered to have an important function in tumor metastasis and the promotion of epithelial‑mesenchymal transition (EMT). E‑cadherin is a crucial factor in intercellular adhesion and EMT transformation. In the present study, we detected the expression of Trop2 and E‑cadherin in breast cancer (BC) to better define their prognostic value. The mRNA expression levels of these two genes in 20 cases of fresh BC tissues were detected by quantitative real‑time polymerase chain reaction (qRT‑PCR)...

Breast cancer is the most common malignancy affecting women, but the heterogeneity of the condition is a significant obstacle to effective treatment. Triple negative breast cancers (TNBCs) do not express HER2 or the receptors for estrogen or progesterone, and so often have a poor prognosis. Tumor-infiltrating T cells have been well-characterized in TNBC, and increased numbers are associated with better outcomes; however, the potential roles of B cells and plasma cells have been large. Here, we conducted a retrospective correlative study on the expression of B cell/plasma cell-related genes, and the abundance and localization of B cells and plasma cells within TNBCs, and clinical outcome...

BACKGROUND: Obesity and type II diabetes are linked to increased breast cancer risk in postmenopausal women. Patients treated with the antidiabetic drug metformin for diabetes or metabolic syndrome have reduced breast cancer risk, a greater pathologic complete response to neoadjuvant therapy, and improved breast cancer survival. We hypothesized that metformin may be especially effective when targeted to the menopausal transition, as this is a lifecycle window when weight gain and metabolic syndrome increase, and is also when the risk for obesity-related breast cancer increases...

PURPOSE: Human Epidermal Growth Factor Receptor 2 (HER2) positive breast cancer is driven by cells possessing stem-like properties of self-renewal and differentiation, referred to as Cancer Stem Cells (CSCs). CSCs are implicated in radiotherapy, chemotherapy resistance, and tumor recurrence. Notch promotes breast CSCs survival and self-renewal, and overexpression of Notch1 and the Notch ligand Jagged1 predict poor outcome. Resistance to anti-HER2 therapy in HER2+ breast cancer requires Notch1, and that combination of trastuzumab and a Gamma Secretase Inhibitor (GSI) prevents tumor relapse in xenograft models...

We aimed to compare the overall survival (OS) and standardized mortality rate (SMR) of the male breast cancer (MBC) with female breast cancer (FBC) after propensity score matching. Based on the Surveillance, Epidemiology, and End Results (SEER), the early breast cancer patients (T1-2 N0-2 M0 ) were extracted from 1998-2007. This study included 1,111 and 2,151 patients with early MBC and FBC, respectively, whose clinicopathological characteristics were well balanced. At a mean follow-up time of 97 months, 10-year OS rate was 58...

Both gains and losses of DNA methylation are common in cancer, but the factors controlling this balance of methylation remain unclear. Triple-negative breast cancer (TNBC), a subtype that does not overexpress hormone receptors or HER2/NEU, is one of the most hypomethylated cancers observed. Here we discovered that the TET1 DNA demethylase is specifically overexpressed in about 40% of patients with TNBC, where it is associated with hypomethylation of up to 10% of queried CpG sites and a worse overall survival...

REVIEW
Petra Wirtz, Freerk T Baumann
The current scientific field of exercise interventions in breast cancer is very large. Rehabilitation focuses on restoring or improving quality of life and thus on independence and participation in life. Hence, it is important to investigate exercise interventions in the setting of rehabilitation and aftercare. It is also necessary to determine the influence of physical activity or exercise therapy on the prevention of recurrence and mortality as well as on certain side effects of the disease and its medical treatment in rehabilitation...

RNA-based multi-target therapies focused in the blocking of signaling pathways represent an attractive approach in cancer. Here, we uncovered a miR-204 cooperative targeting of multiple signaling transducers involved in vasculogenic mimicry (VM). Our data showed that invasive triple negative MDA-MB-231 and Hs-578T breast cancer cells, but not poorly invasive MCF-7 cells, efficiently undergoes matrix-associated VM under hypoxia. Ectopic restoration of miR-204 in MDA-MB-231 cells leads to a potent inhibition of VM and reduction of number of branch points and patterned 3D channels...
