Early parity reduces the risk of breast cancer in women while nulliparity and late parity increase the risk of breast cancer. In order to translate this protection to women where early pregnancy is not feasible, much work has focused on understanding how parity confers protection against breast cancer, the molecular mechanisms by which this occurs is still not well understood. Healthy parous and nulliparous women were recruited for this study. We assessed serum protein profiles of early parous, late parous, and nulliparous women using the Phospho Explorer antibody array...

Breast cancer is a major global health concern, appealing for precise prognostic approaches. Thus, the need is to have studies focusing on the identification and recognition of preliminary events leading to the disease. The present study reports the tracing of precancerous progression and serum proteomic analysis in a breast cancer model developed as a result of 7,12-dimethylbenz[a]anthracene (DMBA) administration. Mammary gland histological changes of prime importance were examined by histopathology, and immunohistochemical analysis with Ki-67 was performed to monitor enhanced cell proliferation, right from the onset of hyperplasia till neoplasia...

The ErbB/B2 (HER-2/neu) oncogene family plays a critical role in the development and metastatic spread of several tumor types including breast, ovarian and gastric cancer. In breast cancer, HER-2/neu is expressed in early disease development in a large percentage of DCIS lesions and its expression is associated with an increased risk of invasion and recurrence. Targeting HER-2 with antibodies such as trastuzumab or pertuzumab has improved survival, but patients with more extensive disease may develop resistance to therapy...

The spread of breast cancer cells to bone and survival in this new metastatic environment is influenced not only by the genetic signature of the cells, but also multiple host cells and soluble factors produced locally (paracrine) or from distant sites (endocrine). Disrupting this metastatic process has been evaluated in clinical trials of the bone targeted agents bisphosphonates and denosumab and have shown that these agents reduce the recurrence of breast cancer in postmenopausal women only, suggesting the efficacy of the drugs are influenced by levels of reproductive endocrine hormones...

The bone marrow microenvironment is characterized by its multicellular nature, and perhaps less obviously by the high mobility of multiple transient and stationary cell lineages present in this environment. The trafficking of hematopoietic and mesenchymal cells between the bone marrow and blood compartments is regulated by a number of bone marrow-derived factors. It is suspected that transformed metastatic cells "hijack" these processes to engraft into the skeleton and eventually cause the skeletal complications associated with metastatic disease...

CONTEXT: Breast cancer is the most common cancer in women worldwide. Estrogen receptor (ER) positive breast cancer constitutes the majority of these cancers. Hormone therapy has significantly improved clinical outcomes for early- and late-stage hormone receptor positive breast cancer. Although most patients with early stage breast cancer are treated with curative intent, approximately 20% - 30% of patients eventually experience a recurrence. During the last two decades, there have been tremendous efforts to understand the biological mechanisms of hormone therapy resistance, with the ultimate goal of implementing new therapeutic strategies to improve the current treatments for ER positive breast cancer...

Our previous phase II clinical trial showed that therapeutically selected personalized peptide vaccines(PPVs)were effective at boosting anticancer immunity; the immune response after PPV was associated with a clinical outcome as a prognostic factor for metastatic breast cancer(mBC). We conducted an early phase II study to evaluate the safety and efficacy of a new regimen using multiple peptide vaccines(KRM-19)for patients with metastatictriple -negative breast cancer. KRM-19 consisted of 19 mixed peptides chosen from the previously reported 31 PPVs according to their anti-tumor immunologiceffec ts and safety profiles for patients with mBC...

Triple-negative breast cancers(TNBCs)are associated with early recurrence after surgery and unfavorable prognoses. To date, no effective therapies for TNBCs have been established. The present study was designed to evaluate the efficacy of adjuvant chemotherapy(ACT)for 111 TNBCs using a retrospective multivariate analysis(MVA). The intravenous(iv)ACTs included docetaxel, epirubicin, gemcitabine, and vinorelbine. The oral ACTs included UFT, doxifluridine, and cyclophosphamide. The 10-year disease-free survival(DFS)and overall survival(OS)rates were 77...

BACKGROUND: The features related to the prognosis of patients with mucinous breast cancer (MBC) remain controversial. We aimed to explore the prognostic factors of MBC and develop a nomogram for predicting survival outcomes. METHODS: The Surveillance, Epidemiology, and End Results (SEER) database was searched to identify 139611 women with resectable breast cancer from 1990 to 2007. Survival curves were generated using Kaplan-Meier methods. The 5-year and 10-year cancer-specific survival (CSS) rates were calculated using the Life-Table method...

PURPOSE: Bimodal age distributions at diagnosis have been widely observed among US and European female breast cancer populations. To determine whether bimodal breast cancer distributions are also present in a sub-Saharan African population, we investigated female breast cancer in South Africa. METHODS: Using the South African National Cancer Registry data, we examined age-at-diagnosis frequency distributions (density plots) for breast cancer overall and by their receptor (oestrogen, progesterone and HER2) determinants among black and white women diagnosed during 2009-2011 in the public healthcare sector...

: The most commonly chosen flaps for delayed breast reconstruction after postmastectomy radiation therapy (PMRT) are abdominal-based free flaps (ABFFs) and pedicled latissimus dorsi (LD) musculocutaneous flaps. The short-and long-term advantages and disadvantages of delayed ABFFs versus LD flaps after PMRT remain unclear. We hypothesized that after PMRT, ABFFs would result in fewer postoperative complications and a lower incidence of revision surgery than LD flaps. METHODS: We retrospectively reviewed a prospectively maintained database of consecutive patients who underwent unilateral, delayed breast reconstruction after PMRT using ABFFs or pedicled LD flaps with implants at the MD Anderson Cancer Center between January 1, 2001, and December 31, 2011...

Effective communication is a requirement in the teamwork necessary for improved coordination to deliver patient-centered, value-based cancer care. Communication is particularly important when care providers are geographically distributed or work across organizations. We review organizational and teams research on communication to highlight psychological safety as a key determinant of high-quality communication within teams. We first present the concept of psychological safety, findings about its communication effects for teamwork, and factors that affect it...

Intercellular communication mediated by extracellular vesicles (EVs), membrane-enclosed packages released by cells, plays important roles in several physiological and pathological settings. Moreover, EVs have been shown to contain molecular signatures that reflect their cell of origin, raising the possibility that EV cargo could potentially be used to diagnose disease. However, for this to occur, a better understanding of the differences between EVs generated by normal and diseased cells is needed. We recently discovered that the content and function of one major class of EVs, microvesicles (MVs), changes upon the induction of oncogenic transformation...
