Our objective was to examine the expression rates of p53, Bcl-2 and Bax in endometrial carcinoma, endometrial hyperplasia and normal endometrium. A total of 94 endometrial frozen sections (carcinoma 48, hyperplasia 21, normal tissue 25) were examined immunohistochemically in terms of the expression rates of p53, Bcl-2 and Bax. All of the specimens in the non-malignant groups were positive for Bax, whereas this rate was 85.4% in the group with malignant specimens (p = .03). Conversely, p53 was expressed only in the cancerous group (77...

In the present study, the RNA sequencing (RNA-seq) data of uterine corpus endometrial carcinoma (UCEC) samples were collected and analyzed using bioinformatics tools to identify potential genes associated with the development of UCEC. UCEC RNA-seq data were downloaded from The Cancer Genome Atlas database. Differential analysis was performed using edgeR software. A false discovery rate <0.01 and |log2(fold change)|>1 were set as the cut-off criteria to screen for differentially expressed genes (DEGs)...

The most common hereditary gynaecological tumour syndromes are hereditary breast and ovarian cancer syndrome and Lynch syndrome. However, pathologists also may encounter gynaecological tumours in women with rare hereditary syndromes. Many of these tumours exhibit distinctive gross and microscopic features that are associated with a risk for an inherited gene mutation. The sensitivity and specificity of these tumour pathology features for predicting an inherited mutation vary depending on the syndrome. By recognising these tumour features, pathologists may potentially contribute to the diagnosis of an unsuspected syndrome by recommending referral of the patient for formal risk assessment by genetic counselling...

Breast cancer rarely metastasizes to the uterus. Here, we report two breast cancer patients with synchronous metastases to the uterus. Case 1 highlights a 46-year-old female with invasive ductal carcinoma who presented with a breast mass and was found to have uterine enlargement on positron emission tomography (PET) scan. Biopsy revealed a metastatic 4 mm focus of breast cancer in the background of endometrial hyperplasia. Case 2 reports a 62-year-old postmenopausal female diagnosed with lobular carcinoma of the breast following an abnormal screening mammogram...

BACKGROUND: European guidelines recommend primary HPV testing for cervical cancer screening. However, the starting age remains to be defined, with an undecided window between 30 and 35 years. This pilot study compares the effectiveness of primary HPV testing to that of cytology for the detection of high-grade (CIN2+) lesions stratified by age. METHODS: Cotesting with LBC cytology and APTIMA(®) HPV (AHPV) was performed in 5053 women aged 25-65 in an opportunistic screening program in Madrid...

Mismatch repair (MMR) deficiency in solid tumors has recently been linked to susceptibility to immunotherapies targeting the programmed cell death-1 (PD-1)/programmed cell death-1 ligand (PD-L1) axis. Loss of MMR proteins has been shown to correlate with tumoral PD-L1 expression in colorectal and endometrial carcinomas, but the association between expression of MMR proteins and PD-L1 has not previously been studied in breast carcinoma, where MMR deficiency is less common. We assessed the relationship between PD-L1 and MMR protein expression by immunohistochemistry in 245 primary and 40 metastatic breast carcinomas...

BACKGROUND/AIM: Occult cancers' reported rates vary from 2-12% and serous tubal intraepithelial carcinomas (STICs) have been identified in 3-12% of the prophylactically removed tubes of women carrying a BRCA mutation. The aim of this study was to evaluate the incidence of tubal minor epithelial atypia (STIL), STIC, and occult invasive cancer and to evaluate the cancer-specific mortality in a prospective series of women at higher risk of ovarian and breast cancer undergoing risk-reducing salpingo-oophorectomy (RRSO) n a tertiary cancer center...

Lynch syndrome (LS) is a hereditary cancer syndrome caused by a germline mutation in a DNA mismatch repair gene, usually MLH1, MSH2, MSH6, or PMS2. The most common cancers associated with LS are colorectal adenocarcinoma and endometrial carcinoma. Identification of women with LS-associated endometrial cancer is important, as these women and their affected siblings and children are at-risk of developing these same cancers. Germline testing of all endometrial cancer patients is not cost effective, and screening using young age of cancer diagnosis and/or presence of family history of syndrome-associated is underutilized and ineffective...

The tumors of the female genital tract represent a leading cause of morbidity and mortality among women worldwide. Substantial progresses have been made in ovarian cancer, with the increasing knowledge about BRCA mutated tumors and the recent development of PARP inhibitors, and in cervical cancer, thanks to extensive screening and widespread of vaccination against Human Papilloma Virus. Nevertheless many needs remain unmet, advanced stage diseases are still incurable and cervical and endometrial carcinoma, as well as platinum-resistant ovarian carcinoma, can certainly be classifiable among the cancers with poor sensitivity to conventional chemotherapy...

Detection of gonadotropin-releasing hormone (GnRH) also known as luteinizing hormone-releasing hormone (LHRH) in the relevant tumor tissue and normal tissues and organs in vivo expression was investigated. To examine the method of direct radio labeling of LHRH by (99m)Tc with relatively high radiochemical purity and stability, screening the best labeling conditions, to establish a simple and reliable method of preparation of (99m)Tc-LHRH was undertaken. The detection of radioisotope-labeled LHRH distribution in mice, LHRH receptor imaging for the study and treatment of cancer basis were evaluated...

Toward the end of his career, Dr. George Papanicolaou became interested in human endometrial explants placed into tissue culture. The initial focus of his studies was on phagocytic cells emanating from endometrial explants and their role in cleansing the uterine cavity after each menstrual cycle and in sterilizing the uterine cavity in the face of infection. Papanicolaou also observed that growth rates of explanted normal and pathologic endometrial tissues differed considerably. Explants of endometrial malignancies exhibited not only increased growth rates but also visible proliferation of cells with readily identifiable cytologic features of malignancy...

Endometrial epithelium is the presumed tissue of origin for both eutopic and endometriosis-derived clear cell and endometrioid carcinomas. We had previously hypothesized that the morphological, biological and clinical differences between these carcinomas are due to histotype-specific mutations. Although some mutations and genomic landscape features are more likely to be found in one of these histotypes, we were not able to identify a single class of mutations that was exclusively present in one histotype and not the other...

Despite a trend towards universal testing, best practice to screen patients presenting with gynaecological malignancy for Lynch syndrome (LS) is uncertain. We report our institutional experience of a co-ordinated gynaecological LS screening program. All patients with endometrial carcinoma or carcinosarcoma, or gynaecological endometrioid or clear cell carcinomas undergo reflex four panel immunohistochemistry (IHC) for MLH1, PMS2, MSH2 and MSH6 followed by cascade somatic hypermethylation analysis of the MLH1 promoter locus for dual MLH1/PMS2 negative tumours...

PTEN hamartoma tumor syndrome (PHTS), DICER1 syndrome, and hereditary leiomyomatosis and renal cell cancer (HLRCC) syndrome are pleiotropic tumor predisposition syndromes that include benign and malignant neoplasms affecting adults and children. PHTS includes several disorders with shared and distinct clinical features. These are associated with elevated lifetime risk of breast, thyroid, endometrial, colorectal, and renal cancers as well as melanoma. Thyroid cancer represents the predominant cancer risk under age 20 years...

BACKGROUND: Many women have undergone both resectoscopic and nonresectoscopic (or global) endometrial ablation (EA) during the past 20 years. These women are now approaching their sixth and seventh decades of life, a time frame in which endometrial carcinoma (EC) is most frequently diagnosed. DATABASE: In several reports, surgeons have expressed concern that endometrial ablation may leave a sequestered island of EC that may escape detection, possibly delaying its diagnosis or causing it to appear at an advanced stage...

Background: Historically the conventional Pap smear has been an effective screening tool for Carcinoma cervix. However the reporting of benign and malignant endometrial cells on Pap smear has remained controversial. There are very few studies addressing the utility of Pap smears in diagnosing endometrial carcinomas. Objective: To rescreen the Pap smears of patients with endometrial adenocarcinoma for the detection of normal/ atypical endometrial cells and to correlate with clinico-pathological parameters. Methods: The present study was carried out at SDM College of Medical Sciences, Dharwad, Karnataka, India for a period of 7 years...

BACKGROUND: Lynch syndrome (LS) is an inherited disorder associated with genetic predisposition to endometrial, colorectal, ovarian, and other cancers. There is consensus for the necessity of assessment for LS in view of the established survival benefits for identified patients and affected family members. The debate regarding the best screening policy is far from being concluded. OBJECTIVES: The aim of this study was to evaluate a realistic protocol for identifying LS families by assessing young women with a diagnosis of endometrial cancer (EC)...

Background: Insulin resistance (IR) has been well studied in the initiation and development of endometrial endometrioid carcinoma (EEC). As yet, it has been largely neglected for estrogen sensitivity in local endometrium in hyperinsulinemia-induced systemic microenvironment. The aim of this study was to investigate the role of insulin in regulating estrogen sensitivity and explore the potential mechanisms in insulin-driven inflammatory microenvironment. Methods: We first investigated the effect of insulin on estradiol-driven endometrial cancer cells proliferation in vitro to address the roles of insulin in modulating estrogen sensitivity...

There have been several updates recently on the classification of uterine tumors. Endometrial carcinomas have traditionally been divided into 2 types, but some are difficult to classify and do not fit readily into either of the currently recognized categories. The Cancer Genome Atlas Research Network has recently defined 4 new categories of endometrial cancer on the basis of mutational spectra, copy number alteration, and microsatellite instability, which might provide independent prognostic information beyond established risk factors...

Plasminogen activator inhibitor type 1 (PAI-1) is a serine protease inhibitor (Serpine 1), and it inhibits both tissue plasminogen activator and urokinase plasminogen activator which are important in fibrinolysis. We aimed to find whether there is a possible association between PAI-1 level, PAI-1 4G/5G polymorphism, and endometrial cancer. PAI-1 levels in peripheral blood were determined in 82 patients with endometrial carcinoma and 76 female healthy controls using an enzyme-linked immunoassay (ELISA). Then, the genomic DNA was extracted and screened by reverse hybridization procedure (Strip assay) to detect PAI 1 4G/5G polymorphism...
