Anti-TNFα-antibodies have revolutionized the therapy of inflammatory bowel diseases and other immune-mediated inflammatory diseases. Due to the increasing application of these substances, the Working Group of Inflammatory Bowel Diseases of the Austrian Association of Gastroenterology and Hepatology intended to update their consensus report on the safe use of Infliximab (published in 2010) and to enlarge its scope to cover all anti-TNFα-antibodies. The present consensus report summarizes the current evidence on the safe use of anti-TNFα-antibodies and covers the following topics: general risk of infection, bacterial infections (i...

Idiopathic granulomatous mastitis (IGM) is a rare benign inflammatory breast entity characterized by lobulocentric granulomas. IGM has a persistent or recurrent disease course and affects parous premenopausal women with a history of lactation. It has also been associated with hyperprolactinemia. The most common clinical sign is a palpable tender mass. However, the nonspecific manifestations and varied demographic features of this condition, as well as the other similar-appearing and superimposed breast entities, pose substantial diagnostic challenges...

OBJECTIVE: The negative impact of malignant disease on sexual and relational functioning is well-documented among adults, but scarcely investigated among adolescents and young adults. This study explored the body image, self-perceived attractiveness and sexual/romantic experiences of Danes diagnosed with cancer at the age of 15-29 years. It also aimed to clarify whether self-perceived needs for counseling were in fact met by health-care providers. METHODS: All Danes who had been diagnosed with cancer at the age of 15-29 years during the period 2009-2013 were included in a cross-sectional nationwide questionnaire study...

Casein kinase-II, a member of protein kinase family, plays significant role in different cellular processes such as cell growth, differentiation, proliferation, gene expression and embryogenesis. Being a potent suppressor of apoptosis, it serves as a significant link for its association with various types of malignancies such as colorectal and breast cancer. To overcome its pathological role in various cancerous diseases, CK-II procures great consideration as a therapeutic target. This study aimed at understanding the binding mechanism and structural properties of benzimidazole derivatives by utilizing various computational tools including docking simulation, 3-dimensional quantitative structure activity relationships and molecular dynamic simulation...

The multifunctional cytokine TGF-β crucially participates in breast cancer (BCa) metastasis and works differently in the disease stages, thus contributing in BCa progression. We address connections between TGF-β and the stem cell-related transcription factor (TF) Oct4 in BCa. In 147 BCa patients with infiltrating duct carcinoma, we identified a significantly higher number of cases with both moderate/high Oct4 expression and high TGF-β in late stages compared to early stages of the disease. In vitro studies showed that TGF-β elevated Oct4 expression, which in turn, regulated Epithelial-to-Mesenchymal transition (EMT)-regulatory gene (Snail and Slug) expression, migratory ability, chemotactic invasiveness and extracellular matrix (ECM) degradation potential of BCa cells...

Breast cancer accounts for about 30% of all cancers in women, while approximately 70% breast cancer patients developed bone metastases throughout the course of their disease, highlighting the importance of exploring new therapeutic targets. Microfibrillar-associated protein 5 (MFAP5) is a component of extracellular elastic microfibril which has been confirmed to function in tissue development and cancer progression. But the role of MFAP5 in breast cancer remains unclear. The present study demonstrated that MFAP5 was up-regulated in breast cancers compared with that in normal breast tissues, and further increased in breast cancer bone metastasis...

BACKGROUND: E-cadherin and vimentin are regarded as major conventional canonical markers of the epithelial-mesenchymal transition. It is commonly assumed that E-cadherin is uniformly lost during the process of epithelial-mesenchymal transition. Breast tumor cells typically invade as a cohesive multicellular unit in a process called collective invasion. The aim of this study was to reveal the clinical importance of the expression pattern of E-cadherin and vimentin in breast cancer. METHODS: E-cadherin and vimentin protein expression was evaluated by immunohistochemistry in 176 invasive breast cancer samples...

Throughout life, mammary tissue is strongly influenced by hormones. Scientists have hypothesized that synthetic chemicals with hormonal activities could disrupt mammary gland development and contribute to breast diseases and dysfunction. Bisphenol S (BPS) is an estrogenic compound used in many consumer products. In this study, CD-1 mice were exposed to BPS (2 or 200 μg/kg/day) during pregnancy and lactation. Mice exposed to 0.01 or 1 μg/kg/day ethinyl estradiol (EE2), a pharmaceutical estrogen, were also evaluated...

Inflammatory breast cancer (IBC) in humans is the most aggressive form of mammary gland cancer and shares clinical, pathologic, and molecular patterns of disease with canine inflammatory mammary carcinoma (CIMC). Despite the use of multimodal therapeutic approaches, including targeted therapies, the prognosis for IBC/CIMC remains poor. The aim of this review is to critically analyze IBC and CIMC in terms of biology and clinical features. While rodent cancer models have formed the basis of our understanding of cancer biology, the translation of this knowledge into improved outcomes has been limited...

BACKGROUND: Young adults with cancer experience disruptions in their normal developmental trajectories and commonly experience psychologic distress related to their diagnoses. Young women with metastatic breast cancer (MBC) are at particular risk of adverse mental health outcomes. OBJECTIVE: We sought to determine the prevalence of and factors associated with anxiety and depression symptoms in young women with newly diagnosed de novo MBC. METHODS: A total of 54 women with newly diagnosed de novo MBC were identified from an ongoing, prospective, multicenter cohort of women diagnosed with breast cancer at age <40...

INTRODUCTION: It is unknown whether the treatment disparity observed between young and elderly women extends to the management of positive margins after initial lumpectomy. The primary aim was to evaluate the management of positive margins after initial lumpectomy in elderly women. METHODS: Women ≥50 y who underwent lumpectomy for stage I-III tumors were identified. Tumor and treatment characteristics were collected across two subgroups: young (50-69 y) and elderly (≥70 y)...

Trastuzumab improves survival outcomes for patients with HER2-positive (HER2+ ) breast cancer, yet not all such women receive this important therapy. Trastuzumab was approved by the US Food and Drug Administration in 1998 and the European Medicines Agency in 2000 as treatment for HER2+ metastatic breast cancer (MBC). Observational studies between 2000 and 2015 in patients with HER2+ MBC suggest that nearly 12% in the United States, 27% to 54% in Europe, and 27.1% to 49.2% in China did not receive trastuzumab or any other HER2-targeted agent as first- and/or later-line for treatment of metastatic disease...

BACKGROUND: Positive margins have been reported in 20-40% of patients undergoing a partial mastectomy (PM), often resulting in re-excision. How often the re-excision yields further cancer and whether there are predictors of residual disease remains unknown. STUDY DESIGN: Patients who had a positive margin (defined as tumor at ink for patients with invasive disease or within 1 mm for patients with DCIS) in the SHAVE trial prior to randomization were evaluated to determine the rate of additional disease either in cavity shave margins (CSM) or at re-excision...

PURPOSE: The purpose of the study is to investigate the prognostic significance of programmed death ligand-1 (PD-L1) expression and tumor-infiltrating lymphocytes (TILs) in HER2+ breast cancer (BC). METHODS: HER2+ BC cases (n  = 191) were collected between 1996 and 2013. Tissue microarray (TMA) slides were stained with two clones of PD-L1 antibodies (28-8 and 22C3) and the percentage of positive membranous staining was scored. TILs of the full sections were also scored using percentage scale...

Sphingosine-1-phosphate (S1P), a bioactive sphingolipid mediator, has been implicated in regulation of many processes important for breast cancer progression. Previously we observed that S1P is exported out of human breast cancer cells by ATP-binding cassette (ABC) transporter ABCC1, but not by ABCB1, both known multidrug resistance proteins that efflux chemotherapeutic agents. However, the pathological consequences of these events to breast cancer progression and metastasis has not been elucidated. Here, it is demonstrated that high expression of ABCC1, but not ABCB1, is associated with poor prognosis in breast cancer patients...

Breast cancer (BC) is a complex and heterogeneous disease, with distinct histological features dictating the therapy. Although the clinical outcome of BC patients has been considerably improved, the occurrence of resistance to common endocrine and chemotherapy treatments remains the major cause of relapse and mortality. Thus, efforts in identifying new molecules to be employed in BC therapy are needed. As a "faster" alternative to reach this aim, we evaluated if Lamotrigine (LTG), a broadly used anticonvulsivant, could be "repurposed" as an antitumoral drug in BC...
