Certain features of pregnancy are important risk factors for breast cancer, such as protection afforded by young age at first birth. Preeclampsia, a pregnancy complication, is associated with reduced maternal breast cancer risk. However, questions remain regarding causality, biological mechanisms and the relation of other hypertensive conditions to risk. We conducted a population-based case-control study of breast cancer cases (n=116,196) in parous women identified through linkage of birth and cancer registries in Denmark, Finland, Norway and Sweden (1967-2013), including up to 10 matched controls per case (n=1,147,192) sampled from the birth registries (complete data were not available on all variables)...

Wnt signaling is important for breast development and remodeling during pregnancy and lactation. Epigenetic modifications change expression levels of components of the Wnt pathway, underlying oncogenic transformation. However, no clear Wnt component increasing expression universally across breast cancer (BC) or its most Wnt-dependent triple-negative BC (TNBC) subgroup has been identified, delaying development of targeted therapies. Here we perform network correlation analysis of expression of >100 Wnt pathway components in hundreds of healthy and cancerous breast tissues...

Cancer arises from subpopulations of transformed cells with high tumor initiation and repopulation ability, known as cancer stem cells (CSCs), which share many similarities with their normal counterparts. In the mammary gland, several studies have shown common molecular regulators between adult mammary stem cells (MaSCs) and breast cancer stem cells (bCSCs). Cell plasticity and self-renewal are essential abilities for MaSCs to maintain tissue homeostasis and regenerate the gland after pregnancy. Intriguingly, these properties are similarly executed in breast cancer stem cells to drive tumor initiation, tumor heterogeneity and recurrence after chemotherapy...

Breast cancer diagnosed during pregnancy is a rare occurrence at present; however, in recent years a trend towards delayed childbirth is generating an increase in its incidence. This situation requires a multidisciplinary approach involving obstetricians, oncologists and surgeons. In this review we analyse diagnostic methods, different possible treatments and long-term patient prognosis. We conducted a search for articles published in PubMed, or in abstract form from the San Antonio Breast Cancer Symposium (SABCS), the European Society for Medical Oncology (ESMO), and the American Society of Clinical Oncology (ASCO) annual meeting, using the search terms: "Breast cancer and pregnancy"...

Measurement of circulating insulin-like growth factors (IGFs), in particular IGF-binding protein (IGFBP)-2, at the time of diagnosis, is independently prognostic in many cancers, but its clinical performance against other routinely determined prognosticators has not been examined. We measured IGF-I, IGF-II, pro-IGF-II, IGF bioactivity, IGFBP-2, -3, and pregnancy-associated plasma protein A (PAPP-A), an IGFBP regulator, in baseline samples of 301 women with breast cancer treated on four protocols (Odense, Denmark: 1993-1998)...

Purpose The role of temporary ovarian suppression with gonadotropin-releasing hormone agonists (GnRHa) during chemotherapy as a strategy to preserve ovarian function and fertility in premenopausal women remains controversial. This systematic review and meta-analysis using individual patient-level data was conducted to better assess the efficacy and safety of this strategy in patients with early breast cancer. Methods The trials in which premenopausal women with early breast cancer were randomly assigned to receive (neo)adjuvant chemotherapy alone or with concurrent GnRHa were eligible for inclusion...

Surgery, anticoagulation therapy, pregnancy, and hormone treatments, such as bromocriptine, are well-characterized precipitating factors for pituitary apoplexy. However, whether cytotoxic chemotherapy for systemic cancer could cause pituitary apoplexy has not been investigated. Here, we present a case of a 41-year-old woman who developed a severe headache with decreased visual acuity after intravenous cytotoxic chemotherapy to treat metastatic breast cancer. Preoperative neuroimaging revealed pituitary adenoma with necrosis...

BACKGROUND/AIM: Breast cancer 1, early onset (BRCA1) gene is expressed in the cells of the breast and other tissues, where it plays a role in cell-cycle regulation, transcription, repair of DNA double-stranded breaks, ubiquitination, transcriptional regulation as well as other functions, such as cell response regulation to mitogenic signals triggered by estrogens. Considering that meningioma shows greater tumor growth during pregnancy, can express estrogen receptors and proliferate in response to estrogenic stimulation, the hypothesis that this type of tumor may share molecular mechanisms that involve exposure to estrogen should be investigated...

Cancer during pregnancy is a particularly challenging complication. The incidence has increased in recent years due to childbering at an advanced maternal age due to career choices and/or the development of reproductive technology. Approximately two thirds of cancer cases during pregnancy are comprised of invasive cervical cancers and breast cancer. Cancer during gestation is characterized by a need for specialized treatment due to major changes in the hormonal profile (estrogen-progesterone), metabolism (enhancement of anabolism), hemodynamic changes (hyperdynamic circulation), immunologic changes (cell mediated and humoral immunity), increased angiogenesis (increased blood flow towards the uterus)...

The placental multidrug transporters, P-glycoprotein (P-gp, encoded by ABCB1) and breast cancer resistance protein (BCRP, ABCG2) protect the foetus from exposure to maternally derived glucocorticoids, toxins and xenobiotics. During pregnancy, maternal glucocorticoid levels can be elevated by stress or exogenous administration. We hypothesized that glucocorticoids modulate the expression of ABCB1/P-gp and ABCG2/BCRP in the first trimester human placenta. Our objective was to examine whether dexamethasone (DEX) or cortisol modulate first trimester placental expression of multidrug transporters and determine whether cytotrophoblasts or the syncytiotrophoblast are/is responsible for mediating these effects...

Adverse effects on fertility are a significant problem for premenopausal breast cancer patients. Since April 2009, we have been referring young patients for fertility counseling provided by a multidisciplinary team. Here we evaluated the efficacy and safety of our current fertility preservation approach. We retrospectively analyzed the cases of 277 patients < 45 years old at diagnosis, which was made between 2009 and 2016. Seventy-two (26%) patients received fertility counseling. Seventeen (6%) of the 277 patients decided to preserve their fertility before starting adjuvant systemic therapy...

Breast cancer is one of the most common malignancies diagnosed in pregnancy. Although the tumor is often detected at an advanced stage, placental metastases are rare. Here, we describe the case of a woman with breast cancer recurrence during pregnancy and subsequent metastases. The focus of this study is the large amount of placenta metastases, which have been analyzed immunohistochemically. Staining with trophoblast markers (placenta alkaline phosphatase, beta human chorionic gonadotropin and human placental lactogen) showed the strict localization of metastases in the intervillous space without invasion into fetal tissue...

OBJECTIVE: Reproductive decision-making for couples with hereditary breast and ovarian cancer (HBOC) is complex and can result in decisional conflict or -regret. This study investigated couples' support needs and aimed to identify vulnerable couples. Ultimately we should strive to develop a clear standard of care guideline regarding reproductive decision-support. METHODS: Mixed methods were used for data collection. A focus group study was conducted among 18 couples (N=35) with HBOC who had made a reproductive decision after reproductive counselling...

Background: Breast cancer is the most common malignancy among females all over the world. The incidence of breast cancer is persistently on the rise due to urbanization and lifestyle changes. Although various risk factors have been suggested for estimating the risk of developing breast cancer, most of these have been studied in the Western population. A better understanding of local characteristics of risk factors may help in devising locally effective prevention strategies for breast cancer...

Social and health care provision have led to substantial increases in life expectancy. In the UK this has become higher than 80 years with an even greater proportional increase in those aged 85 years and over. The different life stages give rise to important nutritional challenges and recent reductions in milk consumption have led to sub-optimal intakes of calcium by teenage females in particular when bone growth is at its maximum and of iodine during pregnancy needed to ensure that supply/production of thyroid hormones to the foetus is adequate...
