c-Kit proto-oncogene expression in endometrial hyperplasia and endometrial cancer.
PURPOSE: To evaluate the expression of c-kit (CD117) in endometrial hyperplasia and endometrial cancer. METHODS: Expression of c-kit in 10 normal endometrium, 18 simple endometrial hyperplasia, 16 complex endometrial hyperplasia (10 cases with atypia and 6 cases without atypia), and 6 endometrial cancer were investigated by immunohistochemistry. RESULTS: c-Kit expression decreased as the lesion progressed to endometrial cancer. Immunostaining was mostly focal and weak in the normal endometrium and was mostl...
CYP17A1 T-34C polymorphism is not associated with endometrial cancer risk.
The association between CYP17A1 T-34C polymorphism and endometrial cancer risk has been inconsistent and underpowered. To clarify the effect of CYP17A1 T-34C polymorphism on the risk of endometrial cancer, a meta-analysis of all available studies relating CYP17A1 T-34C polymorphism to the risk of endometrial cancer was conducted. The authors searched PubMed, EMBASE, Scopus, and VisionCite databases updated on March 2013. Data were extracted by two independent authors and pooled odds ratio (OR) with 95 % co...
OBJECTIVE: To evaluate the role of endometrial/uterine corporeal volume ratio for the prediction of endometrial malignancy in cases of postmenopausal bleeding. METHODS: Endometrial volumes and uterine body volumes excluding cervices measured by VOCAL (virtual organ computer-aided analysis) were estimated in 160 women with postmenopausal bleeding. Endometrial/uterine corporeal volume ratios were calculated for all. Endometrial biopsies and histopathological results were obtained for all. One hundred normal p...
Enhanced endometrial proliferation correlates obesity to type-I (estrogen-dependent) endometrial cancer (EC). Our aim was to distinguish obese women (without EC) with differing endometrial proliferation. Endometrial and blood samples were obtained from normal-weight and obese women without EC. Type-I EC samples were obtained from obese patients. On measuring endometrial proliferation (Ki67 and phosphorylated histone H3 (p-H3)), two groups of obese women without EC were identified: obese(High Proliferating)...
Obesity, inflammatory markers and endometrial cancer risk: a prospective case-control study.
Obesity, a major risk factor for endometrial cancer, is a low grade inflammatory state characterized by elevated concentrations of cytokines and acute phase reactants. The current study had two aims: first, to investigate the associations of C-reactive protein (CRP), interleukin-6 (IL-6), and interleukin-1 receptor antagonist (IL-1Ra) with endometrial cancer risk and second to examine to which extent these markers can influence the association between obesity and endometrial cancer. We conducted a case-cont...
ABO blood type is associated with endometrial cancer risk in Chinese women.
ABO blood type has been associated with risk of several malignancies. However, results are not consistent. In this population-based case-control study including 1204 incident endometrial cancer cases and 1212 population controls, we examined the association of self-reported serologic blood type with endometrial cancer risk using a logistic regression model. Women with endometrial cancer were more likely to have blood type A. Compared to women with blood type O, the adjusted odds ratios for endometrial cance...
Association of MDM2 SNP309 and TP53 Arg72Pro polymorphisms with risk of endometrial cancer.
The incidence of endometrial cancer, a common gynecological malignancy, is increasing in Japan. We have previously shown that the ER/MDM2/p53/p21 pathway plays an important role in endometrial carcinogenesis. In the present study, we investigated the effects of germline single nucleotide polymorphisms in murine double minute 2 (MDM2) SNP309, TP53 Arg72Pro, ESR1 PvuII and XbaI, and p21 codon 31 on endometrial cancer risk. We evaluated these polymorphisms in DNA samples from 125 endometrial cancer cases and...
Childbearing at an older age has been associated with a lower risk of endometrial cancer, but whether the association is independent of the number of births or other factors remains unclear. Individual-level data from 4 cohort and 13 case-control studies in the Epidemiology of Endometrial Cancer Consortium were pooled. A total of 8,671 cases of endometrial cancer and 16,562 controls were included in the analysis. After adjustment for known risk factors, endometrial cancer risk declined with increasing age a...
Serum leptin-adiponectin ratio and endometrial cancer risk in postmenopausal female subjects.
OBJECTIVE: Obesity is a well-known risk factor for the development of endometrial cancer. Elevated endogenous estrogen and insulin resistance are recognized to be major factors that link obesity and cancer development. However, there is increasing evidence that the adipokines adiponectin and leptin, which are directly produced in adipose tissue, impact several obesity-related cancers. The purpose of the current study was to investigate the relationships of the concentration of leptin, adiponectin, and the l...
The role of hepatocyte growth factor activator inhibitor (HAI)-1 and HAI-2 in endometrial cancer.
Hepatocyte growth factor activator inhibitors (HAI-1 and HAI-2) are Kunitz-type serine protease inhibitors that have a broad inhibitory spectrum against serine proteases. This is the first study to investigate the role of HAI-1 and HAI-2 in endometrial cancer. We investigated the biological functions of HAI-1 and HAI-2 using KLE and HEC-251 endometrial cancer cell lines, thus HAI-1 and HAI-2 were examined in uterine normal endometrium, endometrial hyperplasia and cancer specimens by immunohistochemistry. HA...
OBJECTIVES: Obesity is associated with the incidence of endometrial cancer. At present it is unclear whether it is also associated with cancer recurrence. This analysis evaluated the consequences of weight changes after diagnosis of endometrial cancer during the follow-up. METHODS: Records of patients with endometrial cancer (n = 705) were reviewed for body weight after the diagnosis of cancer during the follow-up and rela...
OBJECTIVES: The goal of this study was to define the diagnostic value of hysteroscopy in evaluating uterine cavity compared to endometrial biopsy in women presenting with postmenopausal bleeding and thick endometrial mucosa with particular attention to endometrial hyperplasia and carcinoma. METHODS: Eighty-three consecutive women presenting with postmenopausal bleeding and endometrial thickness of 5 mm or more measured by transvaginal ultrasound (TVU) were enrolled in a prospective study between May 2008 a...
The main methods of treatment of endometrial carcinoma are hysterectomy and bilateral oophorectomy with lymphadenectomy. However, another option for hormonal treatment of endometrial carcinoma, the use of progesterone in young patients to preserve childbearing capacity, has been reported, and a high remission rate has been described in well-selected stage I, grade 1 endometrial cancer. Although it is intriguing that hormonal therapy alone can treat endometrial carcinoma without surgery or cytotoxic chemothe...
Physical activity and endometrial cancer in a population-based case-control study.
INTRODUCTION: Published studies of physical activity, BMI, and endometrial cancer risk show conflicting results and many do not report on reliability or validity of physical activity questionnaires. METHODS: We collected physical activity data on 667 incident cases of endometrial cancer and 662 age-matched controls. Interview-administered questionnaires, collecting demographic and lifestyle information, including a validated questionnaire for physical activity. We performed unconditional logistic regression...
Non-assessable endometrium in women with post-menopausal bleeding: to investigate or ignore.
BACKGROUND: In women presenting with post-menopausal bleeding (PMB), the incidence of endometrial cancer is 1-10 %; Trans-vaginal scan (TVS) is offered as the first line of investigation to triage women further and a thick endometrium (>4 mm) merits endometrial tissue sampling for further evaluation. When it is difficult and not possible to assess the endometrium sonographically, decision to investigate further lies with the clinician. AIM: Study outcomes for women with PMB and endometrium not assessable...
Effects of a selective COX-2 inhibitor in patients with uterine endometrial cancers.
PURPOSE: COX-2 is highly expressed in endometrial cancers, suggesting that a selective COX-2 inhibitor could be valuable for treating endometrial cancers that overexpress COX-2. In this study, we investigated the anti-tumor effects of the selective COX-2 inhibitor etodolac on endometrial cancer patients. METHODS: Etodolac (400 mg, bid, for 2 weeks) was administered preoperatively to 21 endometrial cancer patients who had provided informed consent. Using pre-treatment biopsies and post-treatment surgical s...
The present medical examinations for detecting endometrial cancer could be sometimes stressful and inconvenient for examinees and examiners. Therefore, we attempted to develop an autoscan-virtual cytology system for detecting endometrial cancer without relying on judgment by the human eye. The exfoliated cells from uterus were retrieved using a tampon inserted for 3 hrs. More than 100 monoclonal antibodies (mAbs) developed by us were screened in three steps of immunohistochemistry to find mAb sets that woul...
Comorbidities and endometrial cancer survival in Hispanics and non-Hispanic whites.
PURPOSE: We investigated comorbidities and endometrial cancer survival by ethnicity because Hispanic whites (HWs) have worse survival than non-Hispanic whites (NHWs). METHODS: An endometrial cancer cohort (1992-2004) established with the Surveillance, Epidemiology and End Results-Medicare-linked database (n = 3,286) was followed through 2007. Endometrial cancer-specific and other cause mortality were evaluated with multivariate hazard ratios (mHRs). RESULTS: HWs were more likely than NHWs to have regional...
PURPOSE: The phosphatidylinositol 3-kinase (PI3K)/PTEN/AKT/mTOR and Ras/Raf/MEK/ERK pathways have been implicated in endometrial tumorigenesis. In this candidate pathway analysis, we investigated associations between genetic variations in these two pathways and both risk and clinical outcomes of endometrial cancer. METHODS: We genotyped a total of 48 potentially functional SNPs in 11 key genes (AKT1, AKT2, AKT3, BRAF, FRAP1,...
Endometrial cancers and predisposition.
As nearly 5% of all endometrial cancers occur because of a predisposition, this possibility has systematically to be explored. The hallmarks of predisposition, a young age at diagnosis, a personal or a familial history of cancer, have to be searched systematically. The identification of a predisposition in a family has a major impact on the management of the proband or his relatives. The endometrial cancer main predisposition is Lynch's syndrome. In this review, we will focus on this condition and describe...
Radiation therapy versus chemoradiation as adjuvant treatment in high-risk endometrial cancer.
Endometrial cancer is a common malignancy. Management of these tumors depends on several risk factors such as FIGO staging, myometrial invasion, histology or pelvic lymph node involvement. According to those factors, low risk, intermediate and high risk groups were defined. A high risk endometrial cancer has a poorer prognostic and more risks of recurrence. Treatment of such disease should be more agressive. However modalities of these treatments have not yet been clearly defined.
Circulating Regulatory T Cells in Endometrial Cancer: A Role for Age and Menopausal Status.
Regulatory T cells (Treg) are a sub-population of T cells that suppress self-reactivity and are implicated in immune tolerance towards malignant cells. Circulating Treg cells are increased in several cancers. In endometrial cancer Treg cells have been investigated only in tumour tissues and, in contrast to some other tumours, fewer Treg cells were reported in endometrial cancer compared with benign controls. Flow cytometry was used to determine the frequency of circulating Treg cells in women undergoing hys...
The etiology and development of human cancers that remain little understood might be enlightened by defining tumor suppressor microRNAs (TS-miRNA). In this study, we identified TS-miRNAs silenced by aberrant DNA hypermethylation in endometrial cancer. Functional screening of 327 synthetic miRNAs in an endometrial cancer cell proliferation assay identified 103 miRNAs that inhibited cell growth. We then determined the sequence, DNA methylation status, and expression levels of these miRNAs in endometrial cance...
Thyroid transcription factor-1 (TTF-1) is a DNA-binding protein that is mainly expressed in thyroid and lung tissue, but has also been found in gynecologic tissue. Recent studies have suggested that TTF-1 has tumor suppressor function in lung adenocarcinoma models. In the current study, we examined whether expression of TTF-1 in benign endometrium and endometrial hyperplasia might impact on the risk of developing endometrial cancer. Formalin-fixed paraffin-embedded endometrial tissues obtained from 535 case...
