Endometrial intraepithelial cancer

Alli Straubhar, Andrew P Soisson, Mark Dodson, Elise Simons
INTRODUCTION: Young women with endometrial intraepithelial hyperplasia or low-grade endometrial carcinoma are potential candidates for conservative fertility sparing therapy utilizing progesterone rather than hysterectomy. High-dose progesterone treatment is associated with 55-80% initial response but high relapse rates. Using aromatase inhibitors in conjunction with high-dose progesterone has largely been unstudied. CASE DESCRIPTIONS: Three obese premenopausal women with endometrial cancer failed to respond to oral or intrauterine progesterone as first line therapy...

An update on the current epidemiology and a review of the risk factors of cervical and endometrial cancers are discussed. Cervical cancer prevention with a focus on human papillomavirus vaccination and cervical cancer screening is reviewed, emphasizing the new focus of less frequent intervention in an effort to maintain high rates of early detection of disease while decreasing unnecessary and anxiety-provoking colposcopies, biopsies, and excisional procedures. The replacement of traditional endometrial hyperplasia terminology with more relevant clinical categories, with an emphasis on the introduction of endometrial intraepithelial neoplasia, is presented...

The cumulative risks of developing epithelial ovarian cancer in women aged 70-75years with BRCA1 and BRCA2 germline mutations are approximately 39-40% and 11-18%, respectively. Here, we present the management of hereditary breast and ovarian cancer(HBOC)in our hospital. HBOC management commences with the selection of appropriate candidates for genetic testing, based on personal and familial characteristics that determine the individual's probability of being a mutation carrier. Pre-test counseling, which is an essential element of genetic counseling, should include discussion of why the test is being offered, how the test results may affect medical management, and the cancer risks associated with the gene mutation...

BACKGROUND: Endometrial hyperplasia (EH) is a uterine pathology representing a spectrum of morphological endometrial alterations. It is predominantly characterized by an increase in the endometrial gland-to-stroma ratio when compared to normal proliferative endometrium. The clinical significance of EH lies in the associated risk of progression to endometrioid endometrial cancer (EC) and 'atypical' forms of EH are regarded as premalignant lesions. Traditional histopathological classification systems for EH exhibit wide and varying degrees of diagnostic reproducibility and, as a consequence, standardized patient management can be challenging...

On a clinicopathological and molecular level, two distinctive types of endometrial carcinoma, type I and type II, can be distinguished. Endometrioid carcinoma, the typical type I carcinoma, seems to develop through an estrogen-driven "adenoma carcinoma" pathway from atypical endometrial hyperplasia/endometrioid intraepithelial neoplasia (AEH/EIN). It is associated with elevated serum estrogen and high body mass index and expresses estrogen and progesterone receptors. They are mostly low grade and show a favorable prognosis...

Cervical cancer is the third most commonly diagnosed cancer in women. The human wings apart-like (hWAPL) gene, which is 30,793 bp long and located on 10q23.2., is a human homologue of the WAPL gene in Drosophila melanogaster. hWAPL has the characteristics of an oncogene in uterine cervical cancer. The present study investigated the expression of the hWAPL gene in tissues, including 9 common cancers, consisting of cervical, gastric and lung cancers, liver, bladder, esophageal, endometrial, renal and rectal carcinomas, cervical intraepithelial neoplasia (CIN) and benign squamous epithelia...

Universal screening for Lynch syndrome through mismatch repair (MMR) immunohistochemistry (IHC) on tumor samples has brought to light several heterogenous MMR staining patterns. At our institution, a prospective study of universal Lynch syndrome screening using MMR IHC on 125 endometrial cancers (EC) led to the identification of subclonal loss of MMR protein expression within the tumor (n=9). We also interrogated the MMR staining patterns in MMR-deficient EC with concurrent endometrial intraepithelial neoplasia (EIN; n=14) and all mixed-type ECs (n=14) to look for concordant or discordant profiles between the various components...

The high-mobility group A protein 2 (HMGA2) is a non-histone chromatin factor highly expressed in fetal tissue and malignant tumors but rarely detected within normal adult tissues. The clinical implications and biological functions of HMGA2 in endometrial carcinoma are largely unknown. Here we report that HMGA2 expression was barely detected in benign endometrium samples (2 of 28 samples). However, HMGA2 expression increased significantly from precancerous lesion endometrial glandular dysplasia (7 of 17, 41...

OBJECTIVES: Abnormal signs or symptoms recorded on Papanicolaou (Pap) test requisitions may reflect disease not detected with Pap testing. Since 2009, these cases have been reviewed in our laboratory by a second cytotechnologist and a cytopathologist. The objective of this study was to document follow-up findings on these patients. METHODS: A search for Pap test results of "Negative for intraepithelial lesion or malignancy, abnormal clinical signs or symptoms" was performed for cases from January 1, 2009, to October 10, 2013...

INTRODUCTION: Intraepithelial CD8+ tumour-infiltrating T-lymphocytes (TIL) are associated with a prolonged survival in endometrial cancer (EC). By contrast, stromal infiltration of CD8+ TIL does not confer prognostic benefit. A single marker to discriminate these populations would therefore be of interest for rapid assessment of the tumour immune contexture, ex vivo analysis of intraepithelial and stromal T-cells on a functional level and/or adoptive T-cell transfer. Here we determined whether CD103, the αE subunit of the αEβ7integrin, can be used to specifically discriminate the epithelial and stromal CD8+ TIL populations in EC...

Ovarian carcinoma is the deadliest gynecological malignancy. Previous studies have suggested that the fallopian tube may be the primary site for high-grade serous carcinoma. In prophylactic salpingo-oophorectomies from women with hereditary high risk for ovarian cancer, precursors can be assessed prior to onset and studied as a model for serous cancer precursor lesions. Epidemiologic studies indicate that carcinogenesis may be a result of chronic fallopian tube injury. The aims of this study were to (1) to examine the incidence of serous tubal intraepithelial carcinoma (STIC) in relation to other clinical parameters and (2) to evaluate whether chronic fallopian tube injury was related to cancer development...
