Thyroid carcinoma (TC) is the most common endocrine neoplasm. The risk of TC as a second primary malignancy (SPM) of breast cancer is significantly increased. Bisphenol A (BPA) is a widely contacted xenoestrogen and increases susceptibility to breast cancer through binding to estrogen receptor alpha (ERα). However, the effect of BPA on thyroid carcinogenesis has not been fully demonstrated. This present study aimed to characterize the effects of BPA on the development of TC using a Fischer 344 (F344) rat model...

Endometrial cancer is the fourth cause of cancer in women in France and is the second most common cancer of the gynecologic cancer after breast cancer with 7275 new cases in 2012. The incidence of this neoplasm tends to increase with population aging, diabetes and obesity's augmentation. In rare cases, a hereditary factor has been described: Lynch's syndrome. The therapeutic management of the patient depends on the endometrial biopsy which specifies the histological type and the histo-prognostic grade as well as the MRI which allow the tumor staging...

BACKGROUND: Breast cancer is the most common malignancy affecting the Iraqi population and the leading cause of cancer related mortality among Iraqi women. It has been well documented that prognosis of patients depends largely upon the hormone receptor contents and HER-2 over expression of their neoplasm. Recent studies suggest that Triple Positive (TP) tumors, bearing the three markers, tend to exhibit a relatively favorable clinical behavior in which overtreatment is not recommended...

The diagnosis of radiation-associated angiosarcoma is challenging and there are overlapping clinicopathological features between radiation-associated benign, atypical and malignant vascular lesions. It has been shown convincingly, that the majority of radiation-associated angiosarcomas are characterised by amplification and subsequent overexpression of MYC in contrast to benign and atypical vascular lesions. Given the fact that epigenetic changes play an important role in carcinogenesis and loss of histone H3K27 trimethylation (H3K27me3) has been found in a number of malignant neoplasms including malignant peripheral nerve sheath tumours, especially when associated with previous radiotherapy, we evaluated the immunohistochemical reaction pattern for H3K27me3 in 49 vascular lesions and control cases: normal skin and benign vascular lesions not associated with previous radiotherapy, radiation-associated benign, atypical and malignant vascular lesions and angiosarcomas not associated with previous radiotherapy...

BACKGROUND: Pseudoangiomatous stromal hyperplasia is an uncommon mesenchymal breast neoplasm. CASE PRESENTATION: Here we present a case of an 11-year old hispanic girl affected by bilateral mammary nodular pseudoangiomatous stromal hyperplasia, an uncommon breast disease, with a review of the literature related to diagnostic workup, differential diagnosis, and management. A rapidly growing mass in the breast may be stressful for both parents and child as the suspicion of malignancy arises...

The ovaries are common site of metastasis in a variety of primary neoplasms. Multiple tumors such as breast, lung, and pancreas have been reported to metastasize to the ovary, however; the colon and stomach are the most common primary cancer sites that of ovarian metastasis. An ovarian mass mostly originates from its self-tissue, but sometimes it can be a metastasis of a gastrointestinal system tumor. Such cases are often misdiagnosed as primary ovarian cancers. A 42-year-old woman was admitted to our hospital with pelvic pain...

OBJECTIVES: Hematological malignancies of the breast share a presentation similar to primary breast carcinomas but differ substantially in therapeutic approach and clinical outcomes. In this study, we investigate the frequency of hematological malignancies, their relative primary and secondary occurrences, and further characterize the distinct histopathologies of these malignancies with a special focus on lymphomas. To our knowledge this is one of the largest and most comprehensive studies of breast hematologic malignancies...

The diagnosis of neuroendocrine neoplasms (NENs) may be challenging and is based on typical morphological features and positive staining for antibodies of neuroendocrine differentiation. Neuron-specific enolase (NSE) being a cytosolic marker may be useful in this setting. NSE is by many considered nonspecific, due to the finding of this marker in tumors considered not to be of neuroendocrine origin. Our aim was to determine whether this is true and whether NSE is more specific than previously realized. We examined 178 tumors (carcinomas and NENs) from breast, lung, stomach, and kidney using immunohistochemistry with the following markers: chromogranin A, synaptophysin, CD56, secretagogin, and NSE...

PURPOSE: To better identify the physiology of triple-negative breast neoplasm (TNBN), we analyzed the TNBN gene regulatory network using gene expression data. METHODS: We collected TNBN gene expression data from The Cancer Genome Atlas to construct a TNBN gene regulatory network using least absolute shrinkage and selection operator regression. In addition, we constructed a triple-positive breast neoplasm (TPBN) network for comparison. Furthermore, survival analysis based on gene expression levels and differentially expressed gene (DEG) analysis were carried out to support and compare the network analysis results, respectively...

Motivation: Identification of disease-associated miRNAs (disease miRNAs) is critical for understanding disease etiology and pathogenesis. Since miRNAs exert their functions by regulating the expression of their target mRNAs, several methods based on the target genes were proposed to predict disease miRNA candidates. They achieved only limited success as they all suffered from the high false-positive rate of target prediction results. Alternatively, other prediction methods were based on the observation that miRNAs with similar functions tend to be associated with similar diseases and vice versa...

INTRODUCTION: NUT midline carcinoma (NMC) is a rare and aggressive epithelial cancer arising from median organs. It is driven by chromosomal translocation t(15;19) involving the rearrangement of NUT (nuclear protein in testis) and BRD4 (bromodomain 4) genes leading to fusion oncoprotein BRD4-NUT. CASE PRESENTATION: We report the case of a woman who was previously treated with induction chemotherapy, surgery, radiotherapy and adjuvant trastuzumab for HER-2 positive invasive ductal carcinoma of the breast...

BACKGROUND: Breast cancer risk prediction models are widely used in clinical settings. Although most of the well-known models were designed based on data collected from western population, yet they have been utilized for surveillance purposes in many limited-resource countries. Given the genetic variations in risk factors that exist between different races, we therefore aimed to develop and validate a tool for breast cancer risk assessment among Sudanese women. METHODS: Using cross-sectional design, 153 subjects were eligible to participate in our study...

INTRODUCTION: The γ-amino butyric acid (GABA) plays important role in the proliferation and migration of cancer cells. The aim of the study was to evaluate the level of GABA in breast cancer, in relation to clinical and epidemiological data. MATERIAL AND METHODS: The study was conducted on 89 patients with breast cancer in stage I-II. GABA level was assessed using spectrofluorometric method in tumour homogenates. Immunoexpression of E-cadherin was evaluated histologically on paraffin fixed specimens...

BACKGROUND: As there is a growing number of long-term cancer survivors, the incidence of carcinogenesis as a late effect of radiotherapy is getting more and more into the focus. The risk for the development of secondary malignant neoplasms might be significantly increased due to exposure of healthy tissue outside of the target field to secondary neutrons, in particular in proton therapy. Thus far, the radiobiological effects of these neutrons and a comparison with photons on normal breast cells have not been sufficiently characterised...
