Abstract
OBJECTIVE To formulate strategies for clinical assessments for endometrial thickening on ultrasound in a postmenopausal woman without bleeding. TARGET POPULATION Postmenopausal women of any age. OUTCOMES To reduce unnecessary invasive interventions and investigations in women with asymptomatic endometrial thickening while selectively investigating women at risk for endometrial cancer. BENEFITS, HARMS, AND COSTS It is anticipated that the adoption of these recommendations would save postmenopausal women unnecessary anxiety, pain, and risk of procedural complications. It is also expected to decrease the cost to the health care system by eliminating unnecessary interventions. EVIDENCE English language articles from Medline, Cochrane, and PubMed databases for relevant peer-reviewed articles dating from 1995 to 2022 (e.g., asymptomatic endometrial thickness, endometrial cancer, postmenopausal bleeding, transvaginal ultrasound, endometrial biopsy, cervical stenosis, hormone therapies and the endometrium, tamoxifen, tibolone, aromatase inhibitors). Results were restricted to systematic reviews and meta-analyses, randomized controlled trials/controlled clinical trials, and observational studies. VALIDATION METHODS The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See Appendix A (Tables A1 for definitions and A2 for interpretations of strong and conditional [weak] recommendations). INTENDED AUDIENCE Physicians, including gynaecologists, obstetricians, family physicians, radiologists, pathologists, and internists; nurse practitioners and nurses; medical trainees, including medical students, residents, and fellows; and other providers of health care of the postmenopausal population. SOCIAL MEDIA ABSTRACT Postmenopausal women often have a thickening of the lining of the uterus found during ultrasound. Without bleeding, an endometrium <11 mm is rarely a serious problem but should be evaluated by a health care provider. SUMMARY STATEMENTS RECOMMENDATIONS.

Estimating risk of endometrial malignancy and other intracavitary uterine pathology in women without abnormal uterine bleeding using IETA-1 multinomial regression model: validation study. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2024; 63:556-563.

Abstract
OBJECTIVES To assess the ability of the International Endometrial Tumor Analysis (IETA)-1 polynomial regression model to estimate the risk of endometrial cancer (EC) and other intracavitary uterine pathology in women without abnormal uterine bleeding. METHODS This was a retrospective study, in which we validated the IETA-1 model on the IETA-3 study cohort (n = 1745). The IETA-3 study is a prospective observational multicenter study. It includes women without vaginal bleeding who underwent a standardized transvaginal ultrasound examination in one of seven ultrasound centers between January 2011 and December 2018. The ultrasonography was performed either as part of a routine gynecological examination, during follow-up of non-endometrial pathology, in the work-up before fertility treatment or before treatment for uterine prolapse or ovarian pathology. Ultrasonographic findings were described using IETA terminology and were compared with histology, or with results of clinical and ultrasound follow-up of at least 1 year if endometrial sampling was not performed. The IETA-1 model, which was created using data from patients with abnormal uterine bleeding, predicts four histological outcomes: (1) EC or endometrial intraepithelial neoplasia (EIN); (2) endometrial polyp or intracavitary myoma; (3) proliferative or secretory endometrium, endometritis, or endometrial hyperplasia without atypia; and (4) endometrial atrophy. The predictors in the model are age, body mass index and seven ultrasound variables (visibility of the endometrium, endometrial thickness, color score, cysts in the endometrium, non-uniform echogenicity of the endometrium, presence of a bright edge, presence of a single dominant vessel). We analyzed the discriminative ability of the model (area under the receiver-operating-characteristics curve (AUC); polytomous discrimination index (PDI)) and evaluated calibration of its risk estimates (observed/expected ratio). RESULTS The median age of the women in the IETA-3 cohort was 51 (range, 20-85) years and 51% (887/1745) of the women were postmenopausal. Histology showed EC or EIN in 29 (2%) women, endometrial polyps or intracavitary myomas in 1094 (63%), proliferative or secretory endometrium, endometritis, or hyperplasia without atypia in 144 (8%) and endometrial atrophy in 265 (15%) women. The endometrial sample had insufficient material in five (0.3%) cases. In 208 (12%) women who did not undergo endometrial sampling but were followed up for at least 1 year without clinical or ultrasound signs of endometrial malignancy, the outcome was classified as benign. The IETA-1 model had an AUC of 0.81 (95% CI, 0.73-0.89, n = 1745) for discrimination between malignant (EC or EIN) and benign endometrium, and the observed/expected ratio for EC or EIN was 0.51 (95% CI, 0.32-0.82). The model was able to categorize the four histological outcomes with considerable accuracy: the PDI of the model was 0.68 (95% CI, 0.62-0.73) (n = 1532). The IETA-1 model discriminated very well between endometrial atrophy and all other intracavitary uterine conditions, with an AUC of 0.96 (95% CI, 0.95-0.98). Including only patients in whom the endometrium was measurable (n = 1689), the model's AUC was 0.83 (95% CI, 0.75-0.91), compared with 0.62 (95% CI, 0.52-0.73) when using endometrial thickness alone to predict malignancy (difference in AUC, 0.21; 95% CI, 0.08-0.32). In postmenopausal women with measurable endometrial thickness (n = 848), the IETA-1 model gave an AUC of 0.81 (95% CI, 0.71-0.91), while endometrial thickness alone gave an AUC of 0.70 (95% CI, 0.60-0.81) (difference in AUC, 0.11; 95% CI, 0.01-0.20). CONCLUSION The IETA-1 model discriminates well between benign and malignant conditions in the uterine cavity in patients without abnormal bleeding, but it overestimates the risk of malignancy. It also discriminates well between the four histological outcome categories. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Risk of endometrial cancer in asymptomatic postmenopausal women in relation to ultrasonographic endometrial thickness: systematic review and diagnostic test accuracy meta-analysis. Am J Obstet Gynecol 2023; 228:22-35.e2. [PMID: 35932873 DOI: 10.1016/j.ajog.2022.07.043] [Citation(s) in RCA: 21] [Impact Index Per Article: 21.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Revised: 07/05/2022] [Accepted: 07/20/2022] [Indexed: 01/26/2023]
Abstract
OBJECTIVE This study aimed to evaluate the risk of endometrial carcinoma and atypical endometrial hyperplasia in asymptomatic postmenopausal women concerning the endometrial thickness measured by stratified threshold categories used for performing subsequent endometrial sampling and histologic evaluation. DATA SOURCES MEDLINE, Scopus, ClinicalTrials.gov, SciELO, Embase, the Cochrane Central Register of Controlled Trials, LILACS, conference proceedings, and international controlled trials registries were searched without temporal, geographic, or language restrictions. STUDY ELIGIBILITY CRITERIA Studies were selected if they had a crossover design evaluating the risk of atypical endometrial hyperplasia and endometrial carcinoma in postmenopausal asymptomatic women and calculated the diagnostic accuracy of transvaginal ultrasonography thresholds (at least 3.0 mm) confirmed by histopathologic diagnosis. METHODS This was a systematic review and diagnostic test accuracy meta-analysis according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses of Diagnostic Test Accuracy and Synthesizing Evidence from Diagnostic Accuracy Tests guidelines. Endometrial thickness thresholds were grouped as follows: from 3.0 to 5.9 mm; between 6.0 and 9.9 mm; between 10.0 and 13.9 mm; and ≥14.0 mm. Quality assessment was performed using the Quality Assessment Tool for Diagnostic Accuracy Studies 2 tool. Publication bias was quantified using the Deek funnel plot test. Coprimary outcomes were the risk of atypical endometrial hyperplasia or endometrial carcinoma according to the endometrial thickness and diagnostic accuracy of each threshold group. RESULTS A total of 18 studies provided the data of 10,334 women who were all included in the final analysis. Overall, at an endometrial thickness threshold of at least 3.0 mm, the risk of atypical endometrial hyperplasia or endometrial carcinoma was increased 3-fold relative to women below the cutoff (relative risk, 3.77; 95% confidence interval, 2.26-6.32; I2=74%). Similar degrees of risk were reported for thresholds between 3.0 and 5.9 mm (relative risk, 5.08; 95% confidence interval, 2.26-11.41; I2=0%), 6.0 and 9.9 mm (relative risk, 4.34; 95% confidence interval, 1.68-11.23; I2=0%), 10.0 and 13.9 mm (relative risk, 4.11; 95% confidence interval, 1.55-10.87; I2=86%), and ≥14.0 mm (relative risk, 2.53; 95% confidence interval, 1.04-6.16; I2=78%) with no significant difference among subgroups (P=.885). Regarding diagnostic accuracy, the pooled sensitivity decreased from thresholds below 5.9 mm (relative risk, 0.81; 95% confidence interval, 0.49-0.85) to above 14.0 mm (relative risk, 0.28; 95% confidence interval, 0.18-0.40). Furthermore, the specificity increased from 0.70 (95% confidence interval, 0.61-0.78) for endometrial thickness between 3.0 and 5.9 mm to 0.86 (95% confidence interval, 0.71-0.94) when the endometrial thickness is ≥14.0 mm. For 3.0 to 5.9 mm and 10.0 to 13.9 mm thresholds, the highest diagnostic odds ratios of 10 (95% confidence interval, 3-41) and 11 (95% confidence interval, 2-49), with areas under the curve of 0.81 (95% confidence interval, 0.77-0.84) and 0.82 (95% confidence interval, 0.79-0.86), respectively, were retrieved. The summary point analysis revealed that the 3.0 to 5.9 mm cutoff point was placed higher in the summary receiver operator curve space than the other subgroups, indicating increased endometrial carcinoma or atypical endometrial hyperplasia diagnosis using these cutoffs. CONCLUSION Both low and high endometrial thickness thresholds in postmenopausal asymptomatic women seem equally effective in detecting endometrial carcinoma and atypical endometrial hyperplasia. However, although using a 3.0 to 5.9 mm cutoff results in a lower specificity, the offsetting improvement in sensitivity may justify using this cutoff for further endometrial evaluation in patients with suspected endometrial malignancy.

Abstract
It is not standardised what is the endometrial thickness that discriminates between normal and potentially malignant. The objective of this study was to determine the endometrial thickness cut-off point from which the risk of endometrial cancer (EC) increases in asymptomatic postmenopausal women; and to evaluate the risk factors linked to malignant endometrial pathology as well as other associated ultrasound findings.This was a retrospective observational study that included hysteroscopies performed at the Hospital Materno-Infantil on 267 asymptomatic menopausal women with an increase in endometrial thickness (AET) >5 mm, from 2015 to 2019. The results shows that the prevalence of malignant pathology in asymptomatic postmenopausal women with a casual finding of endometrial thickening was 3.7%. This percentage was 16.3% when the cut-off point of AET was established at 10 mm. There was a significant association for the diagnosis of malignant pathology with this cut-off point.There is a significant association between the 10 mm endometrial thickness cut-off point from which the risk of EC increases in asymptomatic postmenopausal women.Impact statementWhat is already known on this subject? Several studies have established the cut-off point for asymptomatic endometrial thickening (AET) for atypical endometrial hyperplasia and endometrial cancer at 10 mm. Although no cut-off point has optimal accuracy for the diagnosis of malignant endometrial pathology, it has been found that with a cut-off value of AET >10 mm no cases are missed. Likewise, a cut-off point of AET > 11 mm may provide a balance between cancer detection and histopathological workup extension.What do the results of this study add? A significant association was found at the cut-off point of AET > 10 mm, which suggests that screening postmenopausal women at this thickness is acceptable and unlikely to miss cases of endometrial hyperplasia and endometrial cancer.What are the implications of these findings for clinical practice and/or further research? After analysing our results we can conclude, like other published studies, that by establishing a cut-off point of 10 mm we obtain a good discrimination between benign and malignant pathology, which would allow us to diagnose 100% of malignant pathology. Above this cut-off point, the risk of endometrial cancer increases, and it would therefore be advisable to extend the study. A multicentre study is needed to confirm the cut-off point at which the risk of endometrial cancer increases in postmenopausal women with asymptomatic endometrial thickening.

Abstract
Introduction/Purpose To evaluate the endometrial thickness (ET) as a predictor of endometrial abnormalities in postmenopausal women and whether consideration of baseline risk factors increases diagnostic accuracy. Methods This is a retrospective observational study of postmenopausal women presenting with bleeding or thickened endometrium (≥4 mm) on ultrasound, between 2003 and 2012. Risk factors for endometrial abnormality were analysed using logistic regression. Of 301 women, 220 were symptomatic and 81 were asymptomatic. The median ET was 6 mm (IQR 4-9) for symptomatic women and 9 mm (IQR 6-12) for asymptomatic women. Results Abnormal pathology was found in 35 symptomatic (15.9%) and 6 asymptomatic women (7.4%). For each 1 mm increase in ET, the odds of an abnormal diagnosis increased by 16.3% (95% CI 9.6-23.5) for symptomatic and 19.9% (95% CI 3.1-39.3) for asymptomatic women. The Youden's index method identified an ET threshold of ≥7.1mm for symptomatic and ≥14.5mm for asymptomatic women. In symptomatic women the sensitivity was 88.6% (95% CI 72.3-96.3) and specificity 69.2% (95% CI 61.9-75.6), while in asymptomatic women the sensitivity was 50.0% (95% CI 13.9-86.1) and specificity was 89.3% (95% CI 79.5-95.0). The addition of age in the symptomatic women model reduced the sensitivity (82.9% (95% CI 65.7-92.8)) but increased the specificity (72.4% (95% CI 65.3-78.6)). Conclusion ET is a significant predictor of abnormality. In the absence of risk factors, our study suggests that invasive procedures may be withheld until the ET is ≥7.1 mm with bleeding and ≥14.5 mm in asymptomatic women with no bleeding.

Abstract
BACKGROUND An incidental finding of a thickened endometrium on ultrasound in the postmenopausal patient without bleeding is a common presentation to gynaecological services; however there is limited evidence to guide clinical practice as to when hysteroscopic evaluation and endometrial sampling is required. AIMS To determine the endometrial thickness at which endometrial sampling is indicated in asymptomatic postmenopausal women referred with thickened endometrium on ultrasound. MATERIALS AND METHODS A single-centre retrospective case series of postmenopausal women without bleeding undergoing hysteroscopy was conducted. Logistic regression was used to examine the association between a range of variables and pre-malignant or malignant pathology and endometrial thickness. The optimal endometrial thickness threshold was identified to maximise model sensitivity. RESULTS A total of 404 postmenopausal women were included in this study, having undergone a hysteroscopy at the study site between 1 July 2008 and 30 June 2018. The mean (SD) age of patients at presentation was 65 (9.09) years and the mean body mass index was 29.86 kg/m2 (6.52). Of these women, nine (2.2%) were diagnosed with endometrial carcinoma and seven (1.7%) had endometrial hyperplasia with atypia. The most common histopathological finding was of a benign endometrial polyp (153: 37.9%). When including hyperplasia with or without atypia in histopathology of interest, a cut-off of ≥9 mm provides the greatest sensitivity (83.3%) and specificity (63.8%) for a diagnosis of pre-malignant or malignant pathology (classification accuracy of 64.8%; area under the receiver operating characteristic: 0.7358, 95% CI: 0.6439, 0.8278) in this cohort. CONCLUSIONS Using an endometrial thickness of ≥9 mm can be used as a cut-off for endometrial sampling in postmenopausal women without bleeding.

Abstract
OBJECTIVES Numerous studies indicate that endometrial thickness of ≤ 4 mm on transvaginal ultrasound (TVS) is a reliable test to exclude endometrial cancer in women with postmenopausal bleeding (PMB), such that biopsy is not needed. However, not all postmenopausal women have anatomy that allows reliable measurement of endometrial thickness. This study was undertaken to evaluate the frequency of, and the reasons for, an inability to adequately visualize the endometrium on TVS. METHODS A total of 472 consecutive asymptomatic postmenopausal women underwent TVS as part of their routine gynecological care. Their charts and TVS images were reviewed, and, if possible, endometrial thickness was recorded. If the endometrium was not adequately visualized, the reason for inadequacy was recorded, as judged by the examiner. Other demographic characteristics recorded included the number of years since menopause, body mass index (BMI) and current use of hormone replacement therapy. RESULTS Of the 472 women, 292 (61.9%) had an endometrium that was well visualized, in whom endometrial thickness could be measured reliably (mean, 3.0 (range, 1.0-28.0) mm). In the other 180 postmenopausal women (38.1%), a distinct endometrium was not adequately visualized. The reasons for non-visualization were fibroids (n = 95, 20.1% of the overall cohort), adenomyosis (n = 35, 7.4% of the overall cohort) and an axial uterus (n = 50, 10.6% of the overall cohort). Mean interval from menopause was 14.0 (range, 1-50) years and 14.1 (range, 1-40) years in the visualized and non-visualized cohorts, respectively (P = 0.83). Mean BMI was 23.9 (range, 16.3-41.5) kg/m2 in the visualized cohort and 25.4 (range, 18.0-39.9) kg/m2 in the non-visualized cohort (P = 0.015). CONCLUSIONS TVS has become an accepted first step in the evaluation of PMB. However, in our cohort, 38.1% of women had anatomical reasons for non-visualization of the endometrium and lack of a reliable endometrial thickness measurement, including fibroids, adenomyosis or an axial uterus. There was no significant difference between groups in the interval from menopause or current use of hormone replacement therapy, but the mean BMI of the non-visualized group was significantly higher than in the visualized group. Clinicians should be cognizant of these potential limitations of TVS in the initial evaluation of women with PMB. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Feasibility and safety of total laparoscopic hysterectomy for uteri weighing from 1.5 kg to 11.000 kg. Arch Gynecol Obstet 2020; 303:169-179. [PMID: 32949285 DOI: 10.1007/s00404-020-05799-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Accepted: 09/11/2020] [Indexed: 12/12/2022]
Abstract
PURPOSE To assess the feasibility and safety of total laparoscopic hysterectomy (TLH) for uteri ≥ 1.5 kg. METHODS We prospectively evaluated all elective TLHs (with or without adnexectomy) performed for fibromatous uteri between August 2009 and August 2019 in the Department of Obstetrics and Gynecology, Sirai Hospital, Carbonia, and the Department of Gynecologic Oncology, Businco Hospital, Azienda Ospedaliera Brotzu, Cagliari. Patients with large myomatous uteri (uterine weight ≥ 1.5 kg on pathology reports) were included in the analysis. We examined all procedures and collected data about intra- and post-operative short-term and long-term complications, intraoperative blood loss, operative time, hospital stay, and time to achieve well-being. RESULTS Seventy-eight patients were included. The median weight was 2,000 g (range 1,500-11,000 g), estimated blood loss was 100 mL (range 10-700 mL), operating time was 135 min (range 60-300 min), and hospital stay was 2 days (range 2-5 days). Conversion to laparotomy occurred in 4 patients (5.1%) with uterine weight ranging from 3 to 5.5 kg, due to severe adherence syndrome or inadequate visualization. As for intraoperative complications, 1 patient (who had the largest removed uterus weighing 11,000 g) experienced an intraoperative ureteral injury (grade III). No major postoperative complications occurred. CONCLUSIONS This study provides the largest case series of TLH for fibromatous uteri > 1.5 kg and includes some of the largest uteri reported to date in the literature (weighing 5,320, 5,720, and 11,000 g, respectively). The study reaffirms the feasibility and safety of a minimally invasive hysterectomy even in the case of abnormally large uteri.

Abstract
A 55-years-old woman menopausal for the last 6 years discovered to have an endometrial thickness (ET) > 12 mm (suspected endometrial polyp) during routine evaluation in the gynaecology clinic using the transvaginal ultrasound (TVS). Departmental ultrasound confirmed the same TVS findings and suggested the presence of endometrial polyp as the main cause of the ET. Based upon the patient's risk factors (diabetic, hypertensive, obese with family history of endometrial cancer), a departmental decision was taken to proceed for diagnostic hysteroscopy and polypectomy after informed written consent. Large endometrial polyp and submucosal fibroid were found and excised during hysteroscopy. The histopathological results confirmed the intraoperative diagnosis of the endometrial polyp and submucosal fibroid. This report supports the American College of Obstetricians and Gynecologists recommendations and highlights that the TVS is not an appropriate screening tool for asymptomatic postmenopausal women. In addition, the ET > 4 mm in asymptomatic postmenopausal women does not need evaluation.

Endometrial thickness cut-off value by transvaginal ultrasonography for screening of endometrial pathology in premenopausal and postmenopausal women. Obstet Gynecol Sci 2019; 62:445-453. [PMID: 31777741 PMCID: PMC6856473 DOI: 10.5468/ogs.2019.62.6.445] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Revised: 04/12/2019] [Accepted: 05/28/2019] [Indexed: 11/08/2022] Open
Abstract
Objective To assess the clinical usefulness and diagnostic accuracy of ultrasonographic measurement of endometrial thickness (ET) in women with endometrial hyperplasia or cancer (EH+). Methods This retrospective cohort study included 29,995 consecutive women who underwent transvaginal ultrasonography (TVS) for an incidental finding of a thickened endometrium at the health screening and promotion center at Asan Medical Center between 2006 and 2010. Among 959 patients with endometrial abnormalities, 92 patients were included in this study. A total of 867 patients were excluded: 416 were lost to follow-up; 263 did not undergo endometrial biopsy; 155 had endometrial polyps; 17 had submucosal myomas; and 16 had insufficient tissue samples. Endometrial histology was the reference standard for calculating accuracy. Results Of the 92 patients, 78 (84.8%) had normal pathology, while 14 (15.2%) had endometrial pathology (EH+), including 5 patients (35.7%) with simple hyperplasia without atypia, 3 (21.4%) with complex hyperplasia, and 6 (42.9%) with endometrial carcinoma, all stage Ia. The area under the receiver-operating characteristic curve was 0.75 (95% confidence interval [CI], 0.593-0.906). The cut-off value for ET was 8 mm, indicating that TVS ET had a fair accuracy in diagnosing carcinoma, had a sensitivity of 100% (95% CI, 62.9-100.0%) and a specificity of 24.3% (95% CI, 15.2-36.3%). Conclusion TVS is useful for detecting EH+, with a cut-off value for ET of 8 mm having a high sensitivity for detecting endometrial pathologies and the ability to identify women highly unlikely to have EH+, thereby avoiding more invasive endometrial biopsy.

Abstract
Cancer of the endometrium is the most common type of gynecologic cancer in the United States. Vaginal bleeding is the presenting sign in more than 90% of postmenopausal women with endometrial carcinoma. Clinical risk factors for endometrial cancer, including but not limited to age, obesity, use of unopposed estrogen, specific medical comorbidities (eg, polycystic ovary syndrome, type 2 diabetes mellitus, atypical glandular cells on screening cervical cytology), and family history of gynecologic malignancy also should be considered when evaluating postmenopausal bleeding. The clinical approach to postmenopausal bleeding requires prompt and efficient evaluation to exclude or diagnose endometrial carcinoma and endometrial intraepithelial neoplasia. Transvaginal ultrasonography usually is sufficient for an initial evaluation of postmenopausal bleeding if the ultrasound images reveal a thin endometrial echo (less than or equal to 4 mm), given that an endometrial thickness of 4 mm or less has a greater than 99% negative predictive value for endometrial cancer. Transvaginal ultrasonography is a reasonable alternative to endometrial sampling as a first approach in evaluating a postmenopausal woman with an initial episode of bleeding. If blind sampling does not reveal endometrial hyperplasia or malignancy, further testing, such as hysteroscopy with dilation and curettage, is warranted in the evaluation of women with persistent or recurrent bleeding. An endometrial measurement greater than 4 mm that is incidentally discovered in a postmenopausal patient without bleeding need not routinely trigger evaluation, although an individualized assessment based on patient characteristics and risk factors is appropriate. Transvaginal ultrasonography is not an appropriate screening tool for endometrial cancer in postmenopausal women without bleeding.

[PMID: 30113073 DOI: 10.1002/jcu.22631] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/30/2018] [Revised: 06/22/2018] [Accepted: 07/09/2018] [Indexed: 06/08/2023]
Abstract
PURPOSE To evaluate the risk of endometrial cancer and/or endometrial hyperplasia with atypia in asymptomatic postmenopausal women with endometrial thickness ≥ 11 mm. METHODS Systematic review of literature using database search (PubMed and Web of Science) of articles published between January 1990 and December 2016 evaluating the correlation between endometrial thickness as measured by transvaginal ultrasound (double layer) and histopathological findings in asymptomatic postmenopausal women, using the following terms: "endometrial thickness," "postmenopausal," "postmenopause," and "asymptomatic." Inclusion criteria were prospective or retrospective studies of more than 150 cases that provided information on endometrial thickness and its correlation with histopathological data. Studies that included patients with hormone replacement therapy, tamoxifen, or aromatase inhibitors were excluded. The overall relative risk (RR) for EC/EHA was calculated, stratifying the patients into two groups according to endometrial thickness (<11 mm and ≥11 mm). Heterogeneity was assessed by calculating I2 . RESULTS The search identified 289 studies. After exclusions, nine articles that met all the inclusion criteria were included, comprising data from 4751 women. The prevalence of endometrial cancer and/or endometrial hyperplasia with atypia was 2.4%. The relative risk of endometrial cancer and/or endometrial hyperplasia with atypia in the ≥11 mm group was 2.59 (95% CI: 1.66-4.05). High heterogeneity was observed between studies (I2 : 57.3%, P = .016). CONCLUSIONS Overall the risk for EC/EHA was 2.6 times greater in women with ET ≥11 mm vs women with ET 5-10 mm, although there was significant heterogeneity in estimates across studies.

Abstract
PURPOSE To evaluate the risk for endometrial cancer (EC) in a large series of asymptomatic patients with thickened endometrium at ultrasound examination based on previously published data of a theoretical cohort. METHODS In a prospective register study, a total of 1024 women with thickened endometrium in ultrasound examination undergoing histological diagnosis by dilation, hysteroscopy and curettage were evaluated. 124 patients were excluded due to current medication with tamoxifen and/or presence of HNPCC leaving 900 patients for further analysis. RESULTS Mean [standard deviation (SD)] age of patients was 65.6 (8.6) years. Mean (SD) endometrial thickness was 11.9 (5.8) mm. 32 and 6 cases of EC and complex endometrial hyperplasia with atypia were found, respectively. In the univariate analysis, a statistically significant association between endometrial thickness, current use of antihypertensive medication, number of deliveries, and the presence of endometrial fluid in preoperative vaginal ultrasound (p < 0.05) with EC was found. A multivariate logistic regression model incorporating these parameters showed a statistically significant independent association of endometrial thickness, number of deliveries, and the presence of endometrial fluid in preoperative vaginal ultrasound (p < 0.05), but not current use of antihypertensive medication, with EC. Using a cut-off of the endometrial thickness of > 11 mm, the risk for "EC alone" and "EC and complex endometrial hyperplasia with atypia combined" was found to be 6.7% and 7.9%, respectively. CONCLUSIONS Our data compare favorably to a theoretical cohort suggesting a clinically reasonable cut-off of > 11 mm endometrial thickness to discriminate between "normal" and "pathological". The data regarding "risk for endometrial cancer" can be used for counseling affected women.

Abstract
BACKGROUND There is evidence that premenopausal hormones may persist for variable time after menopause. Histological specimens from postmenopausal women support the presence of follicular growth at that age. Residual ovarian function may explain postmenopausal bleeding (PMB), which is not associated with endometrial pathology. Our objective was to evaluate the effect of sonographic diagnosis of simple ovarian cysts on the association between thickened endometrium and endometrial pathology in women with PMB. MATERIALS AND METHODS Data were retrospectively collected from medical records of women who underwent office hysteroscopy for PMB between January 2007 and October 2011. Women with sonographic reports within 3 months of presentation were included. Endometrial thickness and the presence of a simple ovarian cyst (≤5 cm) were documented by reviewing sonographic reports. Diagnosis of endometrial pathology was abstracted according to pathology reports or hysteroscopic impression. Endometria with hyperplasia, cancer, or polyps were considered pathological. RESULTS Of 836 women with PMB, 356 had recent transvaginal sonography and were included in the analysis. Pathological endometrium was documented in 129 (36.2%) women, including 29 (8.2%) with endometrial cancer. In women with PMB and no evidence of a simple ovarian cyst, endometrial thickness was an independent predictor of endometrial pathology and endometrial cancer with adjusted OR = 1.13 (95% CI = 1.07-1.19) and 1.16 (95% CI = 1.07-1.25), respectively. In the presence of simple ovarian cysts, the adjusted ORs for endometrial thickness as a predictor of endometrial pathology were 1.06 (95% CI = 0.90-1.25) and 0.84 (95% CI = 0.62-1.14), respectively. CONCLUSION The presence of simple ovarian cysts (≤5 cm) tempers the value of endometrial thickness in predicting endometrial pathology in women with PMB.

Abstract
Background: Abnormal uterine bleeding (AUB) is the most common presenting symptom of endometrial hyperplasia (EH). Transvaginal ultrasonography (TVS) is a diagnostic tool in the evaluation of AUB and EH with various sensitivity and specificity. However, the exact accuracy of TVS in diagnosing EH had not been evaluated. In this study, we aim to evaluate the accuracy of TVS in detecting EH. Materials and Methods: In this retrospective study, 120 women (mean age of 48.64 ± 6.74 years) with AUB with suspicious/or possible EH were evaluated. TVS and pathology findings of possible EH were recorded. Sensitivity, specificity, positive, and negative predictive value (PPV and NPV) was calculated. Results: Sixty-eight patients were premenopause, and 52 were postmenopause. TVS reported EH in 85 cases (70.83%). Pathology results showed EH in 85 cases (70.83%) including simple cystic hyperplasia in 82 cases, atypical, simple hyperplasia in one case and complex hyperplasia in two cases. Among these 85 cases, EH was confirmed by pathology in 81 cases. The accuracy, sensitivity, specificity, PPV, and NPV were 88.25%, 90.7%, 84%, 97.7%, and 84% in premenopause and 100% in postmenopause women. Conclusion: TVS is an appropriate diagnostic tool in premenopause and postmenopause women presenting with AUB, especially in detecting EH. However, further studies are needed to determine the exact accuracy of TVS in diagnosing TVS.

Abstract
Breast, ovarian and endometrial cancers cause significant morbidity and mortality. Despite the presence of existing screening, diagnostic and treatment modalities, they continue to pose considerable unsolved challenges. Overdiagnosis is a growing problem in breast cancer screening and neither screening nor early diagnosis of ovarian or endometrial cancer is currently possible. Moreover, treatment of the diversity of these cancers presenting in the clinic is not sufficiently personalized at present. Recent technological advances, including reduced representation bisulfite sequencing, methylation arrays, digital PCR, next-generation sequencing and advanced statistical data analysis, enable the analysis of methylation patterns in cell-free tumor DNA in serum/plasma. Ongoing work is bringing these methods together for the analysis of samples from large clinical trials, which have been collected well in advance of cancer diagnosis. These efforts pave the way for the development of a noninvasive method that would enable us to overcome existing challenges to personalized medicine.

Abstract
Introduction Endometrial hyperplasia has a high risk for malignant transformation and relapses; existing mini-invasive treatments may lead to irrevocable endometrium destruction. The aims were to analyze receptor systems in endometrial hyperplasia, to evaluate the capabilities of ultrasonography, sonoelastography for diagnosis and treatment control, and to develop treatment algorithm. Materials and methods We included 313 women (20–45 years), assessed into the following: group 1 (n = 112) with glandular cystic hyperplasia, group 2 (n = 98) endometrial polyps, and group 3 (n = 103) atypical hyperplasia; and 82 controls who have undergone hysteroscopy before in vitro fertilization in tubal origin infertility were also included. Patients underwent clinical examination, transvaginal ultrasound, immunohistochemical study, and hormonal therapy/hysteroresectoscopy. Results In patients with glandular hyperplasia, we registered increase of endometrium estrogen receptors (75.6% in the epithelium and 30.9% in the stroma; in controls, 43.3% and 29.6%, respectively); in polyps, there was a significant estrogen receptor increase in the stroma (48.2% vs 29.6% in controls), and in atypical hyperplasia, progesterone receptors significantly increased in the stroma. Ki-67 increased (40% to 50%) in the epithelium without changes in the stroma. Ultrasound has a sensitivity of 96% and a specificity of 85% for early detection of endometrial pathology and prediction outcome of intervention, and sonoelastography has a sensitivity of 91% and a specificity of 83% for polyp diagnosis. Personalized treatment was effective in 88.8%, relapse was diagnosed in 11.2% after 6 months, and conservative treatment of atypical hyperplasia was effective in 45%: in 25.8%, ablative hysteroresectoscopy was performed, while in 22.6% with comorbidities, hystero/oophorectomies were performed. Conclusions The evaluation of receptor status with ultrasound data in patients with endometrial hyperplasia allows for a clear definition of the treatment policy, avoidance of relapse, treatment optimization, and observation of such patients.

Abstract
OBJECTIVE The goal of this study was to evaluate the true prevalence of endometrial pathology in asymptomatic postmenopausal estrogen receptor-positive (ER-positive) breast cancer patients and to know whether some patients are particularly at risk. METHODS A preliminary cross-sectional study was carried out with 130 postmenopausal ER-positive breast cancer patients. Before any treatment, diagnostic hysteroscopy and endometrial biopsy were performed in all women. Histopathological findings were considered the gold standard in estimating the prevalence of endometrial disease, which was analyzed according to different risk factors. RESULTS Hysteroscopic evaluation was possible in 118 patients (90.7%). Of these patients, 68.6% were older than 60 years, and 51.4% were obese. Endometrial polyps were found in 35 patients (29.6%; 1 polyp with simple hyperplasia), and simple endometrial hyperplasia was found in 1 patient (0.8%), with an overall morbidity of the endometrium of 31.3%. Among all the well-established individual risk factors for endometrial pathology, only patient age, body mass index, and time since menopause were significant predictors of endometrial pathology and/or polyps. There was no statistical difference in the thicknesses of the endometrial lining, but many patients with an endometrial lining of less than 4 mm had polyps of less than 5 mm. CONCLUSIONS Asymptomatic postmenopausal women with ER-positive breast cancer have a very high prevalence of baseline subclinical endometrial abnormalities. Therefore, endometrial screening before tamoxifen treatment may be useful in all of these patients, and we believe that it should be performed by hysteroscopy in patients at high risk (obese and older women).

Abstract
OBJECTIVES Measurement of endometrial thickness is an important tool in the assessment of women with postmenopausal bleeding, but the role of endometrial thickness measurement by ultrasound in asymptomatic women is unclear. The aims of this study were to determine: (1) the normal endometrial thickness measured by ultrasonography, (2) the prevalence of serious endometrial pathology and (3) the sensitivity and specificity of endometrial thickness measurement by transvaginal ultrasonography (TVS) for diagnosing premalignant and malignant endometrial disease in asymptomatic postmenopausal women. METHODS A MEDLINE and EMBASE search (from inception to January 2011) was performed. Articles reporting on endometrial thickness measurement in the diagnosis of endometrial carcinoma and atypical hyperplasia in asymptomatic postmenopausal women not using hormone replacement therapy (HRT) were selected. Endometrial thickness and the prevalence of endometrial (pre)malignancies were recorded. If possible, 2 × 2 tables were extracted. RESULTS Thirty-two studies reporting on 11100 women were included. The estimated mean endometrial thickness was 2.9 mm (95% CI, 2.6-3.3 mm). The pooled estimated prevalences of endometrial carcinoma and atypical endometrial hyperplasia were 0.62% (95% CI, 0.42-0.82%) and 0.59% (95% CI, 0.22-0.96%), respectively. Summary estimates for sensitivity and specificity of TVS endometrial thickness measurement in the prediction of endometrial carcinoma were 0.83 (95% CI, 0.19-1.00) and 0.72 (95% CI, 0.23-0.95) for a 5-mm cut-off and 0.33 (95% CI, 0.04-0.85) and 0.94 (95% CI, 0.92-0.96) for a 6-mm cut-off. CONCLUSIONS The results from this systematic review do not justify the use of endometrial thickness as a screening test for endometrial carcinoma and atypical endometrial hyperplasia in asymptomatic postmenopausal women not using HRT.

Abstract
Background Population-based studies on endometrial cancer providing survival estimates by age, histology, and stage have been sparse. We aimed to derive most up-to-date and detailed survival estimates for endometrial cancer patients in Germany. Methods We used a pooled German national dataset including data from 11 cancer registries covering a population of 33 million people. 30,906 patients diagnosed with endometrial cancer in 1997-2006 were included. Period analysis was performed to calculate 5-year relative survival (RS) in 2002-2006. Trends in survival between 2002 and 2006 were examined using model-based period analysis. Age-adjustment was performed using five age groups (15-44, 45-54, 55-64, 65-74, and 75+ years). Results Overall, age-adjusted 5-year relative survival in 2002-2006 was 81%. A moderate age gradient was observed, with 5-year RS decreasing from 90% in the age group 15-49 years to 75% in the age group 70+ years. Furthermore prognosis varied strongly by histologic subtypes and stage, with age-adjusted 5-year RS ranging from 43% (for sarcoma) to 94% (for squamous metaplasia), and reaching 91% for localized, 51% for regional, and 20% for distant stage. Except for age group 65-74 years, no significant improvement in survival was seen during the recent 5-year period under investigation. Conclusion In this comprehensive population-based survival analysis of patients with endometrial cancer from Germany, prognosis of endometrial cancer moderately varied by age, and strongly varied by histology and stage. While prognosis is rather good overall, further improvement in 5-year relative survival of endometrial cancer patients has been stagnating in the early 21st century.

Abstract
OBJECTIVE To formulate clinical recommendations for the assessment of endometrial thickening when it is found on ultrasound in a postmenopausal patient without bleeding. OUTCOMES Ensure that women with asymptomatic thickening and endometrial polyps found on ultrasound are managed appropriately. EVIDENCE Published literature was retrieved through searches of English language articles from the EMBASE, Cochrane, and PubMed databases for relevant peer-reviewed articles dating from 1970 to 2009, using appropriate controlled vocabulary (e.g., "asymptomatic endometrial thickness," "endometrial cancer," "postmenopausal bleeding," "transvaginal ultrasonography," "endometrial biopsy" and "endometrial polyp"). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. Searches were updated on a regular basis and incorporated in the guideline to April 2010. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALUES The level of evidence was determined according to the criteria established by the Canadian Task Force on Preventative Health Care (Table). Recommendations are ranked according to this method. BENEFITS, HARMS, AND COSTS It is anticipated that the adoption of these recommendations would save postmenopausal women unnecessary anxiety, pain, and risk of procedural complication. It is also expected to decrease the cost to the health system by eliminating unnecessary interventions.

Abstract
BACKGROUND The increase in the worldwide incidence of endometrial cancer relates to rising obesity, falling fertility, and the ageing of the population. Transvaginal ultrasound (TVS) is a possible screening test, but there have been no large-scale studies. We report the performance of TVS screening in a large cohort. METHODS We did a nested case-control study of postmenopausal women who underwent TVS in the United Kingdom Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) following recruitment between April 17, 2001, and Sept 29, 2005. Endometrial thickness and endometrial abnormalities were recorded, and follow-up, through national registries and a postal questionnaire, documented the diagnosis of endometrial cancer. Our primary outcome measure was endometrial cancer and atypical endometrial hyperplasia (AEH). Performance characteristics of endometrial thickness and abnormalities for detection of endometrial cancer within 1 year of TVS were calculated. Epidemiological variables were used to develop a logistic regression model and assess a screening strategy for women at higher risk. Our study is registered with ClinicalTrials.gov, number NCT00058032, and with the International Standard Randomised Controlled Trial register, number ISRCTN22488978. FINDINGS 48,230 women underwent TVS in the UKCTOCS prevalence screen. 9078 women were ineligible because they had undergone a hysterectomy and 2271 because their endometrial thickness had not been recorded; however, 157 of these women had an endometrial abnormality on TVS and were included in the analysis. Median follow-up was 5·11 years (IQR 4·05-5·95). 136 women with endometrial cancer or AEH within 1 year of TVS were included in our primary analysis. The optimum endometrial thickness cutoff for endometrial cancer or AEH was 5·15 mm, with sensitivity of 80·5% (95% CI 72·7-86·8) and specificity of 86·2% (85·8-86·6). Sensitivity and specificity at a 5 mm or greater cutoff were 80·5% (72·7-86·8) and 85·7% (85·4-86·2); for women with a 5 mm or greater cutoff plus endometrial abnormalities, the sensitivity and specificity were 85·3% (78·2-90·8) and 80·4% (80·0-80·8), respectively. For a cutoff of 10 mm or greater, sensitivity and specificity were 54·1% (45·3-62·8) and 97·2% (97·0-97·4). When our analysis was restricted to the 96 women with endometrial cancer or AEH who reported no symptoms of postmenopausal bleeding at the UKCTOCS scan before diagnosis and had an endometrial thickness measurement available, a cutoff of 5 mm achieved a sensitivity of 77·1% (67·8-84·3) and specificity of 85·8% (85·7-85·9). The logistic regression model identified 25% of the population as at high risk and 39·5% of endometrial cancer or AEH cases were identified within this high risk group. In this high-risk population, a cutoff at 6·75 mm achieved sensitivity of 84·3% (71·4-93·0) and specificity of 89·9% (89·3-90·5). INTERPRETATION Our findings show that TVS screening for endometrial cancer has good sensitivity in postmenopausal women. The burden of diagnostic procedures and false-positive results can be reduced by limiting screening to a higher-risk group. The role of population screening for endometrial cancer remains uncertain, but our findings are of immediate value in the management of increased endometrial thickness in postmenopausal women undergoing pelvic scans for reasons other than vaginal bleeding.

Abstract
Background To date, there is no consensus on the utility of screening procedures for the early detection of endometrial cancer. The value of transvaginal ultrasound for screening of asymptomatic endometrial cancer has been discussed controversially. This study was conducted to evaluate whether asymptomatic patients with endometrial cancer have a better prognosis than symptomatic patients with endometrial cancer diagnosed after postmenopausal bleeding. Methods In the present multi-center study, the effect of the presence of postmenopausal bleeding on prognosis was evaluated retrospectively in 605 patients with endometrial cancer using patients' files. 543 patients (133 patients were asymptomatic, 410 patients were symptomatic) with endometrioid endometrial cancer were enrolled in all further analysis. Student's t-test, Cox regression analysis and Kaplan-Meier analysis were used were appropriate. Results Presence/absence of a postmenopausal bleeding was not associated with tumor stage (p = 0.2) and age at diagnosis (p = 0.5). Asymptomatic patients with endometrial cancer had a significantly higher rate of well and moderate-differentiated tumors compared to symptomatic patients (p = 0.008). In univariable and multivariable survival analysis, tumor stage, tumor grade, and patients' age at diagnosis, but not presence/absence of a postmenopausal bleeding, were associated with disease free and overall survival. Conclusion Asymptomatic patients with endometrial cancer have a higher rate of well differentiated tumors compared to patients with a postmenopausal bleeding prior to diagnosis. The prognosis of both groups of patients was similar.

Abstract
There are no screening tests for endometrial carcinoma, and patients typically present with abnormal uterine bleeding. This article discusses the pathophysiology and clinical work-up of abnormal uterine bleeding, and risk factors for endometrial carcinoma. Atypical complex hyperplasia and the more recently defined endometrial intraepithelial neoplasia are well recognized as precancers. Evolving knowledge of their genetic alterations provides the opportunity to develop molecular markers, so that endometrial diseases may be diagnosed at the precancerous or early invasive stage. Emerging molecular markers also provide the opportunity to develop clinically useful screening tests for the most common malignancy of the female genital tract.

Abstract
The objective of this study was to report the value of diagnostic hysteroscopy and endometrial biopsy for the detection of complex atypical hyperplasia or cancer in asymptomatic human non-polyposis colon cancer (HNPCC) patients. The secondary objective was to evaluate the accuracy of hysteroscopy, using endometrial biopsy as a gold standard. Consecutive patients at risk of HNPCC evaluated between January 1, 1999, and June 30, 2006 were included if they underwent diagnostic hysteroscopy at least once. Patients with a history of hysterectomy and those unwilling to undergo diagnostic hysteroscopy were not included. Yearly follow-up evaluations included diagnostic hysteroscopy, with endometrial biopsy. Hysteroscopic and histologic findings were recorded and compared. We included 62 patients, of whom 13 had mismatch repair gene mutations and 49 met Amsterdam II criteria. Of 125 attempted hysteroscopies, 11 (8%) failed. Hysteroscopy showed normally appearing mucosa in 46 cases, nonmalignant lesions in 65 cases, and possibly malignant lesions in 3 cases with abnormal uterine bleeding. Endometrial biopsy was attempted in 116 cases and failed in 12 (10%). Three cases each of simple hyperplasia and of cancer were diagnosed. No preinvasive or invasive lesions were found in asymptomatic women. When compared to endometrial biopsy, sensitivity of hysteroscopy was 100% for the detection of hyperplasia or cancer. No cases of cancer were diagnosed in asymptomatic patients in our study. However, diagnostic hysteroscopy ensured the diagnosis of endometrial adenocarcinoma in HNPCC women with bleeding. Nevertheless, usefulness and optimal modalities of screening remain to be determined.

Abstract
CONTEXT AND OBJECTIVES Endometrial cancer is the most prevalent type of malignant neoplasia of the genital tract. The objective of this study was to calculate the sensitivity, specificity, accuracy and positive and negative predictive values for diagnostic hysteroscopy, in comparison with histopathological tests, for all lesions of the endometrial cavity. DESIGN AND SETTING Retrospective descriptive study at the public tertiary-level university hospital of Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo. METHODS Diagnostic hysteroscopy was indicated in the following instances: endometrial thickness > 4 mm in asymptomatic patients; postmenopausal bleeding; and irregular endometrium or endometrium difficult to assess from ultrasound, with or without vaginal bleeding. Ultrasound evaluations were carried out no more than three months prior to hysteroscopy. RESULTS There were 510 patients, with a mean age of 61.1+/-2.0 years and mean time elapsed since the menopause of 12.7+/-2.5 years. Endometrial biopsies were performed on 293 patients (57.5%). Histopathological analysis showed that 18 patients presented endometrial carcinoma or typical or atypical hyperplasia, and none of them presented endometrial thickness of less than 8 mm. No significant differences were found between the median thicknesses of the various benign lesions (p > 0.05). In our data, the sensitivity, specificity, accuracy and positive and negative predictive values for cancer or hyperplasia were 94.4%, 97.0%, 96.8%, 68% and 99.6%, respectively. CONCLUSIONS Our results suggest that hysteroscopy is valuable as a diagnostic tool for malignant/hyperplastic and benign lesions, except for submucous myomas, for which the sensitivity was only 52.6%.

Abstract
OBJECTIVE Women from Lynch syndrome/hereditary nonpolyposis colorectal cancer (Lynch/HNPCC) families have an increased lifetime risk of developing endometrial and ovarian cancer. This study models a comparison of management strategies for women who carry a Lynch/HNPCC mutation. METHODS A decision analytic model with three arms was designed to compare annual gynecologic examinations with annual screening (ultrasonography, endometrial biopsy, CA 125) and with hysterectomy with bilateral salpingo-oophorectomy at age 30 years The existing literature was searched for studies on the accuracy of endometrial and ovarian cancer screening using endometrial biopsy, transvaginal ultrasonography, and serum CA 125. The Surveillance, Epidemiology and End Results database from 1988 to 2001 was used to estimate cancer mortality outcomes. RESULTS In the surgical arm, 0.0056% of women were diagnosed with ovarian cancer and 0.0060% of women with endometrial cancer. These numbers increased to 3.7% and 18.4% in women being screened, and 8.3% and 48.7% in women undergoing annual examinations, respectively. Surgical management led to the longest expected survival time at 79.98 years, followed by screening at 79.31 years, and annual examinations at 77.41 years. If starting at age 30 and discounting life years at 3%, surgery still leads to the greatest expected life years. When comparing prophylactic surgery with the screening option, one would need to perform 75 surgeries to save one woman's entire life. For cancer prevention, however, only 28 and 6 prophylactic surgeries would need to be performed to prevent one case of ovarian and endometrial cancer, respectively. CONCLUSION Risk-reducing hysterectomy and bilateral salpingo-oophorectomy may be considered in women with Lynch/HNPCC to prevent gynecologic cancers and their associated morbidities.

Abstract
OBJECTIVES To estimate the pretreatment incidence of endometrial pathology and to prospectively assess the endometrial morbidity emerging during tamoxifen intake for breast cancer. STUDY DESIGN One-hundred and forty-six menopausal breast cancer patients, candidate to receive tamoxifen underwent endometrial assessment by Transvaginal Ultrasonography (TU) before the start of therapy. A double-layered endometrial stripe measuring more than 4mm indicated hysteroscopy and endometrial biopsy. Endometrial abnormalities detected before the start of tamoxifen were treated by operative hysteroscopy or by hysterectomy; no therapy and yearly hysteroscopic follow-up was scheduled for patients showing non-atypical hyperplasias. All women were asked to undergo TU on a yearly basis; during the follow-up period, indication for hysteroscopy and endometrial biopsy were the following: (i) an endometrial lining measured above 4mm at the first time, (ii) at least a 50% increase of endometrial thickness since the last finding in patients previously assessed by hysteroscopy, (iii) a recorded vaginal bleeding, and (iv) previous findings of endometrial hyperplasia. Histopathologic result from biopsy or hysterectomy was the reference test to establish the baseline prevalence of endometrial pathology and the emerging prevalences of morbidity after 12, 24, 36, 48 and 60 months of tamoxifen therapy. RESULTS One-hundred and five patients were followed for 60 months, whereas 113, 126, 137 and 141 patients were evaluated up to 48, 36, 24 and 12 months, respectively. In 44 out of 146 patients, pretreatment TU showed an endometrium thicker than 4mm and in 31 (21.2%) of these patients abnormalities consisting of 16 endometrial polyps, seven polyps harboring simple hyperplasia, four simple hyperplasias, three atypical hyperplasias and one adenocarcinoma were found. During tamoxifen intake benign endometrial abnormalities were detected in 36 out of 114 assessable patients showing normal endometrium before the start of tamoxifen therapy (31.5%) and in seven out of 27 patients with baseline endometrial abnormalities (25.9%). Overall, an endometrial pathology emerged in 30.4% of patients during tamoxifen administration and in no patients we found an atypical lesion. CONCLUSIONS In menopausal breast cancer patients the incidence of endometrial abnormalities before the start of tamoxifen therapy is high and includes 2.7% of atypical pathology. After the diagnosis and treatment of baseline atypical lesions were accomplished, no atypical endometrial lesion emerged after the start of tamoxifen administration. Based on these findings, we believe that pretreatment assessment of endometrium is recommended in all menopausal women candidate to receive tamoxifen therapy.

Abstract
The 2001 Bethesda System for Reporting Cervical Cytology recommends reporting benign exfoliated endometrial cells in women age 40 and older, and a review of the literature supports this recommendation. Stromal cells and histiocytes do not need to be reported. The effect of hormonal therapy on endometrial shedding is reviewed. Clinical information should be provided to the laboratory so that appropriate educational notes can be appended to the cytology report. Benign endometrial cells in premenopausal women in the first half of the cycle are not associated with significant pathology and such women do not need additional evaluation. Significant pathology is also unlikely in the second half of the cycle and evaluation may not be required unless clinically indicated. Initial evaluation of other women with benign endometrial cells may include either endometrial sampling or transvaginal ultrasound. Atypical endometrial cells are associated with a higher rate of significant pathology and should lead to additional evaluation. Additional prospective studies on the management of patients with endometrial cells on Pap tests are needed.

Abstract
Over the years, endometrial cancer has remained the most common gynecologic malignancy in the United States. Two categories of endometrial cancer exist: type I and type II. Type I cancers constitute the majority of cases of endometrial cancer, and the risk factors for this type have been studied in greatest detail. These cancers are driven by estrogen, and many of the risk factors are directly or indirectly linked to a state of excessive estrogen. Protective factors seem to be related to conditions that may result in decreased estrogen exposure. Cure rates for endometrial cancer remain high, mainly because of the early stage at which the majority of cases present. Warning signs of abnormal vaginal bleeding or discharge allow detection of these cancers in their early stages. Screening for these cancers is not effective and often leads to additional unnecessary tests; thus, it is not currently recommended in the general population.

Abstract
AIMS To determine the cut-off level of endometrial thickness for detecting endometrial disease on a large scale of screening and to examine the usefulness of transvaginal ultrasonography (TVS) for endometrial disease screening in asymptomatic postmenopausal Japanese women. METHODS The study involved 1,400 postmenopausal women in whom endometrial thickness was measured with TVS, and then compared with the histopathological diagnosis of endometrial specimens. RESULTS The prevalence of endometrial disease in asymptomatic and symptomatic cases was 2.3 and 21%. In symptomatic cases, at a cut-off limit of 3 mm for endometrial thickness, the sensitivity for detecting endometrial disease was 94%, specificity 70% and positive predictive value 46%. With an endometrial thickness < or = 3 mm, the probability that endometrial disease would be overlooked was 0.025. In asymptomatic cases, the corresponding figures at a cut-off limit of 3 mm were 90, 84, 12% and 0.003. CONCLUSIONS TVS does not appear to be an effective screening method in asymptomatic postmenopausal Japanese women because of the low prevalence of endometrial disease in this population. We recommend a normal cut-off level for endometrial thickness of 4 mm in symptomatic postmenopausal Japanese women.

Abstract
OBJECTIVE The aim of this study is to estimate the prevalence of endometrial pathology before the start of tamoxifen therapy in menopausal breast cancer patients. METHODS Ninety-one gynecologically asymptomatic patients, suffering from estrogen receptor-positive breast cancer and scheduled for adjuvant tamoxifen, underwent pretreatment endometrial assessment. In all patients, a transvaginal ultrasonography was carried out; a double-layered endometrial stripe measuring above 4 mm was considered as abnormal. In these patients, outpatient hysteroscopy and endometrial biopsy were performed. Pathologic findings were considered the reference test in estimating the prevalence of endometrial morbidity. RESULTS In 34 patients (37.3%) a thickened endometrium was an indication for hysteroscopic and pathologic assessment. Endometrial polyps, simple hyperplasias, and complex atypical hyperplasias were found in 10 (10.9%), 4 (4.3%), and 3 (3.2%) patients, respectively, leading to an overall prevalence of baseline endometrial morbidity of 18.6%. Established individual risk factors for development of endometrial pathology, such as body mass index, age at menarche and menopause, and parity, did not significantly differ in patients with and without endometrial abnormalities. Only patients' age (63.8 +/- 8.6 and 52.2 +/- 11.8; P = 0.03) and endometrial thickness (10.5 +/- 3.5 and 3.9 +/- 3.0; P > 0.001) were significant predictive factors of endometrial pathology. CONCLUSIONS Menopausal women with estrogen receptor-positive breast cancer appear to have high risk of baseline subclinical endometrial abnormalities; therefore, an endometrial assessment, before the start of tamoxifen therapy, is always recommended in such patients.

Abstract
In Federation of Bosnia and Herzegovina during 2002 a total of 67 cases of endometrial cancer (ICD 10th Revision Code C54) were registered among female population older then 15 years (1 per 10,000 population). Nine women were diagnosed with non specific malignant uteri neoplasia (C55)--without clarifying if that was cervix or corpus uteri located cancer, but assumption is that these cancers are actually endometrial cancer. Majority of cases are older then 50 years, 48 of them (71.6%), while 29 (28.4%) are from 15 to 49 years old. During 2000 about 189,000 new endometrial cancer cases were reported with 44,700 endometrial cancer deaths in the World. In this paper we presented geographical distribution of cases registered in FB&H, as well as leading risk factors, protective factors and prevention and possibilities for screening methods.

Transvaginal ultrasonography and endometrial cytology as a diagnostic schema for endometrial cancer. Gynecol Obstet Invest 2005; 59:149-54. [PMID: 15637434 DOI: 10.1159/000083089] [Citation(s) in RCA: 29] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2004] [Accepted: 11/11/2004] [Indexed: 11/19/2022]
Abstract
OBJECTIVE To determine whether the combined use of transvaginal ultrasonography and endometrial cytology is an effective diagnostic schema for endometrial cancer and hyperplasia of the uterus. METHODS Five hundred fifty-two women were enrolled in this study. For all subjects, endometrial thickness was evaluated by transvaginal ultrasonography. Endometrial cytology was carried out according to the following criteria: all women with atypical uterine bleeding, for asymptomatic postmenopausal women with endometrial thickness >or=5 mm, and for asymptomatic premenopausal women with endometrial thickness >or=20 mm. When the cytological findings were abnormal, we performed a hysteroscopy-guided biopsy within 2 weeks. Women who received transvaginal ultrasonography alone, or those who showed negative cytology, underwent repeated gynecological examination and transvaginal ultrasonography 3, 6, and 12 months after the first examination. RESULTS Endometrial cytology was done on 129 women (23.4% of all subjects), of whom 14 were diagnosed as 'positive' cytology, 20 as 'suspicious positive', and 95 as 'negative'. A total of 34 women with 'positive' or 'suspicious positive' cytological result underwent hysteroscopy-guided endometrial biopsy. The histological diagnosis of the endometrium included 13 endometrial cancers, 9 endometrial hyperplasias (one atypical hyperplasia and 3 hyperplastic polyps), and 10 normal endometria. As a diagnostic schema for endometrial cancer, this combined method resulted in 100% sensitivity, 99.1% specificity, 92.9% positive predictive value, and 100% negative predictive value. For endometrial hyperplasia, the method resulted in 100% sensitivity, 89.6% specificity, 40.0% positive predictive value, and 100% negative predictive value. CONCLUSION A combination of transvaginal ultrasonography and endometrial cytology may be an effective diagnostic schema for endometrial cancer and hyperplasia.
