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...

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...

BACKGROUND: Adrenomedullin (AM) is a pluripotent peptide first discovered from human pheochromocytoma. AM expression has been shown in various cancer types including endometrium cancer. Bcl-2 is an antiapoptotic protein which might be regulated by AM in hypoxic conditions. The aim of the present study was to investigate the role of AM and Bcl-2 expressions in carcinogenesis of type-1 endometrium cancer. MATERIALS AND METHOD: Study group consisted of 10 proliferative endometrium, 22 simple endometrial hyperplasia, 23 endometrial intraepithelial neoplasia (EIN) and 30 Grade 1 endometrioid adenocarcinoma patients...

BACKGROUND: There exist limited therapeutic opportunities for the treatment of endometrial cancer (EC). Itraconazole, a common anti-fungal agent and a potent inhibitor of the Hedgehog pathway, has been shown to be clinically effective for various types of cancers, but its clinical efficacy for EC is unknown. Herein, we evaluated the efficacy of itraconazole in treating EC. MATERIALS AND METHODS: We performed immunohistochemistry on EC tumour samples including serous endometrial intraepithelial carcinoma (SEIC)...

Serous tubal intraepithelial carcinoma (STIC), the putative precursor of the majority of extrauterine high-grade serous carcinomas, has been reported in both high-risk women (those with a germline BRCA mutation, a personal history of breast carcinoma, and/or family history of breast or ovarian carcinoma) and average risk women from the general population. We reviewed grossly normal adnexal specimens from 388 consecutive, unselected women undergoing surgery, including those with germline BRCA mutation (37 patients), personal history of breast cancer or family history of breast/ovarian cancer (74 patients), endometrial cancer (175 patients), and a variety of other conditions (102 patients)...

This study was conducted to determine whether advancing age is an independent predictor of increased risk of high-grade pathologies among women referred for colposcopy after abnormal cervical cytology. Medical records were reviewed for women with abnormal cervical cytology who underwent colposcopy at Khon Kaen University Hospital. Logistic regression was used to determine the independent impact of age on the risk of high-grade pathologies. Mean age of the women was 42.8 years. Of 482 women, 97 (20.1%) were postmenopausal, and 92 (19...

OBJECTIVE: Patients with endometrial intraepithelial neoplasia may have concurrent endometrial cancer if managed surgically or develop cancer in time if managed conservatively. Therefore, intraoperative assessment of the uterus may be helpful if a surgical approach is decided on. Our study aimed to investigate the role of frozen-section examination in patients with endometrial intraepithelial neoplasia. MATERIAL AND METHOD: Patients with endometrial intraepithelial neoplasia who were subjected to hysterectomy with intraoperative frozen-section assessment were included...
