Breast cancer is the leading cause of cancer-related death in women worldwide. Invasive ductal carcinoma (IDC) is the most frequent invasive form of breast cancer followed by metastasis. There is no accepted marker for distinguishing this form from other less aggressive forms of breast cancer. Therefore, finding new markers especially molecularly detectable ones are noteworthy. It has been shown that NOTCH1 has been overexpressed in the patients with breast cancer, but no study has investigated the expression of NOTCH1 and its correlation with other molecular and hormonal markers of breast cancer so far...

This paper proposes a texture analysis technique that can effectively classify different types of human breast tissue imaged by Optical Coherence Microscopy (OCM). OCM is an emerging imaging modality for rapid tissue screening and has the potential to provide high resolution microscopic images that approach those of histology. OCM images, acquired without tissue staining, however, pose unique challenges to image analysis and pattern classification. We examined multiple types of texture features and found Local Binary Pattern (LBP) features to perform better in classifying tissues imaged by OCM...

AIMS: Preoperative core needle biopsy (CNB) is commonly used to confirm the diagnosis of breast cancer. For treatment purposes and for determining histological type, especially in case of neoadjuvant therapy, oestrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2) status and E-cadherin assessments are crucial. Considering the increasing demand for same-day diagnosis of breast lesions, an accelerated method of CNB processing was developed, in which the tissue fixation time is radically reduced...

In prostate cancer, reliable information about the lymph node status is of great importance for accurate staging and the optimal planning of treatment. Despite recent advances in imaging, the histological detection of metastases, or pelvic lymphadenectomy (PLND), continues to be the most reliable method for lymph node staging in clinically localised prostate cancer, especially as this procedure enables the detection of small or micrometastases. Radioisotope-guided sentinel PLND (sPLND) demonstrates high sensitivity in the detection of lymph node metastases as well as low morbidity in prostate cancer because of the targeted removal of a relatively small number of lymph nodes...

ETHNOPHARMACOLOGICAL RELEVANCE: The roots of Actinidia eriantha Benth (AER) are commonly used traditional folk medicine for the treatment of gastric carcinoma, nasopharyngeal carcinoma, and breast carcinoma. Besides, the anti-proliferative and immunomodulatory effects of AER polysaccharides on tumor-bearing mice have been reported previously. AIM OF THE STUDY: This work was carried out to investigate the anticancer and anti-angiogenic activities of AER. MATERIALS AND METHODS: The growth inhibitory effects of ethanol extracts from the leaves (EEL), stems (EES) and roots (EER) of A...

BACKGROUND: Different clinical trials show beneficial effects of physical training offered during and / or after breast cancer treatment. However, given the variety of side effects that may be encountered, physical training could be combined with psychological, relational and social guidance. This kind of multidisciplinary program has been little studied so far. AIM: To determine the benefits of a three-month multidisciplinary rehabilitation program among women after breast cancer treatment...

The insulin receptor substrate (IRS) proteins serve as essential signaling intermediates for the activation of PI3K by both the insulin-like growth factor-1 receptor (IGF-1R) and its close family member the insulin receptor (IR). Although IRS-1 and IRS-2 share significant homology, they regulate distinct cellular responses downstream of these receptors and play divergent roles in breast cancer. To investigate the mechanism by which signaling through IRS-1 and IRS-2 results in differential outcomes, we assessed the involvement of the microtubule cytoskeleton in IRS-dependent signaling...

Antiestrogen-resistant and triple-negative breast tumors pose a serious clinical challenge because of limited treatment options. We assessed global gene expression changes in antiestrogen-sensitive compared with antiestrogen-resistant (two tamoxifen resistant and two fulvestrant resistant) MCF-7 breast cancer cell lines. The branched-chain amino acid transaminase 1 (BCAT1), which catalyzes the first step in the breakdown of branched-chain amino acids, was among the most upregulated transcripts in antiestrogen-resistant cells...

Fine needle aspirations (FNA) of the breast for primary diagnoses have become less popular in the USA and are usually performed for lesions with low or extremely high clinical suspicion. They are also performed for lesions in close proximity to a breast implant. Liquid-based cytological preparations, such as ThinPrep(®) (TP), provide a practical alternative to clinicians who are performing FNA. Using a selection of cases that represent challenging diagnoses, we describe common diagnostic pitfalls of breast FNA that are specifically associated with this preparation...

The current study describes a simple, rapid and eco-friendly method for the synthesis of silver nanoparticles (AgNPs) using Excoecaria agallocha (E. agallocha) leaf extract as stabilizer, bioreductant and capping agent. Synthesized AgNPs were characterized by UV-Visible spectroscopy (UV-Vis), X-ray diffraction (XRD), fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectroscopy (EDX). Generation of AgNPs was initially confirmed with the color change from yellow to dark brown which produces intense absorbance spectra at 440 nm in UV-Vis spectroscopy without any shifting of peaks...

BACKGROUND: Squamous cell carcinoma (SCC) of the breast is a rare and generally aggressive disease that accounts for less than 0.1% of all breast carcinomas. Although SCCs have distinct morphological features, their origin and cytogenetic profile are not well understood. METHODS: Five patients with SCC were studied. The tumor area that was predominantly composed of SCC components was macrodissected and DNA was extracted. In three cases, an invasive or noninvasive ductal carcinoma of no special type (NST) component was also present...

OBJECTIVE: 4-Benzyl-1-(3-iodobenzylsulfonyl)piperidine, 4-B-IBSP, has shown high-binding affinity to both sigma (σ) receptors in our previous work. In current study, radiolabeling and preclinical evaluation of 4-benzyl-1-(3-[(125)I]-iodobenzylsulfonyl)piperidine, 4-B-[(125)I]IBSP, in human ductal breast carcinoma (T47D) cells and in breast adenocarcinoma-bearing BALB/c mice are described. METHODS: Radioiodination of this new σ ligand was performed by a palladium-catalyzed stannylation approach followed by oxidative iododestannylation reaction using Iodo-Gen...

BACKGROUND: A dedicated breast PET scanner with C-shaped detectors (C scanner) has been newly developed. The purpose of this study was to re-evaluate the diagnostic performance of high-resolution PET images with the new reconstruction conditions, obtained using this C scanner in breast cancer patients, and to compare the standardized uptake values (SUVs) of lesions obtained from the C scanner with those from whole-body PET/computed tomography (CT) (WB PET/CT). PATIENTS AND METHODS: A total of 159 female patients with known or suspected breast carcinomas (total 188 lesions: 172 invasive carcinomas; eight noninvasive ductal carcinomas in situ; eight benign lesions) were analysed...

Directed cell migration by contact guidance in aligned collagenous extracellular matrix (ECM) is a critical enabler of breast cancer dissemination. The mechanisms of this process are poorly understood, particularly in 3D, in part because of the lack of efficient methods to generate aligned collagen matrices. To address this technological gap, we propose a simple method to align collagen gels using guided cellular compaction. Our method yields highly aligned, acellular collagen constructs with predictable microstructural features, thus providing a controlled microenvironment for in vitro experiments...

Although mutations in the phosphoinositide 3-kinase-catalytic subunit (PIK3CA) are common in breast cancer, PI3K inhibitors alone have shown modest efficacy. We sought to identify additional pathways altered in PIK3CA mutant tumors that might be targeted in combination with PI3K inhibitors. We generated two transgenic mouse models expressing the human PIK3CA-H1047R and the -E545K hotspot mutant genes in the mammary gland and evaluated their effects on development and tumor formation. Molecular analysis identified pathways altered in these mutant tumors, which were also targeted in multiple cells lines derived from the PIK3CA tumors...
