Narrow band imaging (NBI) for detection of blood vessels and microstructures on the mucosal surface is used in gastrointestinal endoscopy since it can improve qualitative diagnosis and detection of lesion. However, there are no studies on flexible hysteroscopy using NBI. We performed flexible hysteroscopy with NBI for outpatients to investigate the sensitivity and specificity of endoscopic diag...

Previous researchers obtained various apparent diffusion coefficient (ADC) cutoff values to differentiate endometrial carcinoma from benign mimickers with 1.5T magnetic resonance imaging (MRI). Few studies have used 3T MRI or validated the effectiveness of these cutoff ADC values prospectively. This study was designed in two stages to obtain a cutoff ADC value at 3T MRI and to validate prospect...

OBJECTIVES To examine the immunohistochemical expression of cyclooxygenase-2 (COX-2) and nuclear factor-κB (NF-κB) in benign endometrial polyps (EPs), endometrial hyperplasia (EH), endometrial intraepithelial neoplasia (EIN), and endometrioid endometrial cancer (EC). METHODS The immunohistochemical expression of COX-2 and NF-κB was performed using an Aperio Scanscope XT automated system in 21...

Proposed hypothetical causes of endometriosis include retrograde menstruation, lymphatic and vascular metastasis, iatrogenic direct implantation, coelomic metaplasia, embryonic rest, and mesenchymal cell differentiation (induction). Each theory, individually, fails to account for all types of endometriotic lesions, thereby implicating combined and/or type-specific mechanisms. Recent evidence su...

CONTEXT Endometriosis is characterized by the growth of ectopic endometrial tissue. Nerve fibers are frequently associated with ectopic lesions, and neurogenic inflammation may play a role in endometriosis. OBJECTIVE The purpose of this study was to determine the presence of tachykinin receptors in endometriotic lesions and the role of TNFα on their expression. DESIGN This study was an asse...

Endometrial polyps are common pathologic findings in gynecologic pathology practice. Although malignant changes in these lesions are uncommon, numerous studies confirmed this association especially with endometrial serous and clear cell carcinoma. Two cases of malignant endometrial polyps in association with presumed precursor lesion in one of them are presented.

The Tao brush is a small flexible brush used in TruTest Endometrial Biopsy. Endometrial tissue to a depth of 1.5–2 mm can be collected. It gently brushes the entire inside of the uterus so as to gather a more complete sampling of the endometrium and is less painful than the traditional method [1]. It covers a wide area of the endometrial surface. Therefore, small lesions are less likely to be m...

BACKGROUND The transcription factor Forkhead box A1 (FOXA1) is suggested to be important in hormone dependent cancers, although with little data for endometrial cancer. We investigated expression levels of FOXA1 in primary and metastatic endometrial cancer in relation to clinical phenotype, and transcriptional alterations related to FOXA1 status. METHODS Protein expression of FOXA1 was explor...

RATIONALE Endometrial cancer recorded a peak incidence in ages 60-64 years in Romania. Since 2013, an increased trend of endometrial cancer occurrence has been registered in urban areas as compared with rural ones. Unfortunately, most of the cancer cases are diagnosed too late, in an advanced stage of the disease, resulting into diminished lifetime expectancy. The first part of the article conc...
