Wang J, Peng X, Xia E, Xiao Y, Liu Y, Su D, Xu J, Li TC, Huang X. When is it necessary to perform biopsy in asymptomatic postmenopausal women with incidental finding of thickened endometrium? Eur J Obstet Gynecol Reprod Biol 2024; 302:104-110. [PMID: 39243688 DOI: 10.1016/j.ejogrb.2024.08.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Revised: 06/28/2024] [Accepted: 08/10/2024] [Indexed: 09/09/2024]
Abstract
OBJECTIVE To determine the cutoff value for endometrial thickness (ET) that prompts a biopsy in asymptomatic postmenopausal women with an incidental finding of thickened endometrium, and to develop a risk prediction model. METHODS This is a retrospective cohort analysis of the clinical records of the Hysteroscopic Center of Fu Xing Hospital, Capital Medical University, Beijing, China. We collected asymptomatic postmenopausal women who presented with an ET of ≥4 mm (double-layer) as an incidental finding. We stratified the participants into non-malignant and malignant groups based on pathology results and assessed differences between the two groups. A receiver operating characteristic curve (ROC) was used to identify the cutoff value of ET for predicting endometrial malignancy. Logistic regression models were also constructed to predict the risk of malignancy. RESULTS A total of 581 consecutive eligible cases were included. The optimal cutoff value for ET was 8 mm, with a maximum area under the curve (AUC) of 0.755 (95 % CI: 0.645-0.865). In addition to ET, the regression model incorporated diabetes, blood flow signal, BMI, and hypertension to predict the risk of malignancy. A ROC curve constructed for the model yielded an AUC of 0.834 (95 % CI: 0.744-0.924). CONCLUSION It is reasonable to offer hysteroscopy and visually-directed endometrial biopsy for asymptomatic postmenopausal women when ET is 8 mm or above. For those with an ET between 4 and 8 mm, further decision to perform biopsy should be determined on an individual basis, considering risk factors and blood flow signals of the endometrium.

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. [PMID: 37927006 DOI: 10.1002/uog.27530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 10/07/2023] [Accepted: 10/26/2023] [Indexed: 11/07/2023]
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.

Abstract
OBJECTIVE The primary objective of this clinical practice guideline is to provide gynaecologists with an algorithm and evidence to guide the diagnosis and management of endometrial polyps. TARGET POPULATION All patients with symptomatic or asymptomatic endometrial polyps. OPTIONS Options for management of endometrial polyps include expectant, medical, and surgical management. These will depend on symptoms, risks for malignancy, and patient choice. OUTCOMES Outcomes include resolution of symptoms, histopathological diagnosis, and complete removal of the polyp. BENEFITS, HARMS, AND COSTS The implementation of this guideline aims to benefit patients with symptomatic or asymptomatic endometrial polyps and provide physicians with an evidence-based approach toward diagnosis and management (including expectant, medical, and surgical management) of polyps. EVIDENCE The following search terms were entered into PubMed/Medline and Cochrane: endometrial polyps, polyps, endometrial thickening, abnormal uterine bleeding, postmenopausal bleeding, endometrial hyperplasia, endometrial cancer, hormonal therapy, female infertility. All articles were included in the literature search up to 2021 and the following study types were included: randomized controlled trials, meta-analyses, systematic reviews, observational studies, and case reports. Additional publications were identified from the bibliographies of these articles. Only English-language articles were reviewed. 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 weak recommendations). INTENDED AUDIENCE Gynaecologists, family physicians, registered nurses, nurse practitioners, medical students, and residents and fellows. TWEETABLE ABSTRACT Uterine polyps are common and can cause abnormal bleeding, infertility, or bleeding after menopause. If patients don't experience symptoms, treatment is often not necessary. Polyps can be treated with medication but often a surgery will be necessary. SUMMARY STATEMENTS RECOMMENDATIONS.

Abstract
OBJECTIVE To investigate the factors related to endometrial cancer (EC) in postmenopausal women with endometrial thickening and the value of endometrial thickness (ET) in predicting EC. METHODS A retrospective study of 385 referrals to our department for hysteroscopic diagnostic curettage assessment was carried out. Univariate analysis and multiple logistic regression analysis were used to identify the independent contributors to the development of EC. The ability of ET to predict EC was evaluated by receiver operating characteristic curve analysis. RESULTS The follow-up period from the identification of endometrial thickening to pathological confirmation of EC was from 2 weeks to 3 months. In the postmenopausal bleeding (PMB) group, a total of 47 participants' specimens were pathologically malignant. Older age and polypoid mass-like lesions ( P < 0.001) were independent factors associated with EC. The optimal critical value of ET in predicting EC was 9.5 mm, with a sensitivity and specificity of 70.21% and 70.67%, respectively. In the non-PMB group, six participants had evidence of malignant pathology, and only polypoid mass-like lesions were an independent factor associated with EC ( P < 0.001). CONCLUSIONS For postmenopausal women with increased ET and PMB, older age, thicker ET, and polypoid mass-like lesions on transvaginal ultrasound were independent associated factors for EC. An ET greater than 9.5 mm is a threshold for predicting EC. For postmenopausal women with increased ET without PMB, the incidence of endometrial malignancy is low. If the woman has polypoid mass-like lesions on transvaginal ultrasound, she should receive further attention.

Abstract
This practice guideline provides updated evidence for the gynecologist who performs endometrial biopsy (EB) in gynecologic clinical practice. An international committee of gynecology experts developed the recommendations according to AGREE Reporting Guideline. An adequate tissue sampling is mandatory when performing an EB. Blind methods should not be first choice in patients with suspected endometrial malignancy. Hysteroscopy is the targeted-biopsy method with highest diagnostic accuracy and cost-effectiveness. Blind suction techniques are not reliable for the diagnosis of endometrial polyps. In low resources settings, and in absence of the capacity to perform office hysteroscopy, blind techniques could be used for EB. Hysteroscopic punch biopsy allows to collect only limited amount of endometrial tissue. grasp biopsy technique should be considered first choice in reproductive aged women, bipolar electrode chip biopsy should be preferred with hypotrophic or atrophic endometrium. EB is required for the final diagnosis of chronic endometritis. There is no consensus regarding which endometrial thickness cut-off should be used for recommending EB in asymptomatic postmenopausal women. EB should be offered to young women with abnormal uterine bleeding and risk factors for endometrial carcinoma. Endometrial pathology should be excluded with EB in nonobese women with unopposed hyperestrogenism. Hysteroscopy with EB is useful in patients with abnormal bleeding even without sonographic evidence of pathology. EB has high sensitivity for detecting intrauterine pathologies. In postmenopausal women with uterine bleeding, EB is recommended. Women with sonographic endometrial thickness > 4mm using tamoxifen should undergo hysteroscopic EB.

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
OBJECTIVE To analyze the clinical and pathological features of asymptomatic postmenopausal women with an incidentally detected increase in endometrial thickness (ET) by transvaginal ultrasound examination and discuss the cutoff value of ET for the timely discovery of endometrial malignancy. METHODS This was a retrospective study of postmenopausal women with asymptomatic thickened endometrium (greater than or equal to 5 mm) screened by transvaginal ultrasound who were referred to the gynecology department at Xuanwu Hospital between January 2018 and March 2021. Data on participant demographics, clinical characteristics, and histopathology outcomes were collected. We stratified the participants into the benign group and malignant group according to pathology results and assessed differences between the two groups. A receiver operating characteristic curve was used to identify the cutoff value of ET for predicting endometrial malignancy in postmenopausal women with asymptomatic thickened endometrium. RESULTS A total of 163 eligible cases were included in the analysis. The results showed that only ET was significantly different between the two groups. The median ET was significantly higher in the malignant group than in the benign group (1.20 vs 0.80, P = 0.023). The optimal cutoff value of ET was 10 mmwith the maximum AUC (0.881, 95% CI 0.810-0.952, P = 0.024), and the sensitivity and specificity for the diagnosis of endometrial malignancy were 100%and 80%, respectively. Among the 47 women with ET ≥ 10mm, the prevalence of endometrial malignancy was 6.3%, which was significantly higher than that among women with ET < 10mm ( P = 0.023). CONCLUSION For postmenopausal women with asymptomatic endometrial thickening, the prevalence of endometrial malignancy is significantly higher when ET is ≥ 10 mm. If ET is ≥ 10mm, further histopathological testing should be recommended to exclude endometrial malignancy. Further large-sample and prospective studies are needed to determine the predictive value of ET.

Abstract
OBJECTIVE To evaluate the clinicopathological characteristics and risk factors for endometrial malignancy in postmenopausal women with endometrial thickening. METHODS This was a retrospective study. Postmenopausal women with endometrial thickening (defined as the thickest endometrial portion in the sagittal uterine plane was greater than or equal to 5 mm) through transvaginal ultrasound in our outpatient department, and further referred to the gynecology department at Xuanwu Hospital for hysteroscopic diagnostic curettage assessment between January 2018 and March 2021 were included. According to the histopathological results, participants were divided into the benign group and malignant group. Univariate analysis was used to compare the differences in various factors, including demographics, clinical characteristics, medical complications, and ultrasound characteristics, between the two groups. Multiple logistic regression analysis was used to identify the factors that were independent contributors to the development of endometrial malignancy. Receiver operating characteristic analysis of endometrial thickness (ET) to predict endometrial malignancy was performed. RESULTS In total, 385 eligible cases were included in the analysis. The results suggested that older age (odds ratio [OR] 1.061, 95% confidence interval [CI] 1.008-1.116, P = 0.023), thicker ET (OR 5.032, 95% CI 2.453-10.322, P < 0.001), irregular menstruation in the past (OR 19.203, 95% CI 1.936-190.431, P = 0.012), postmenopausal bleeding (OR 12.341, 95% CI 4.440-34.302, P < 0.001), and polypoid mass-like lesions (OR 30.330, 95% CI 8.974-102.509, P < 0.001) were risk factors that were independently associated with the development of endometrial malignancy in postmenopausal women with increased ET. The optimal critical value of ET in predicting malignancy was 9.5 mm, and the sensitivity and specificity were 71.70% and 71.69%, respectively. CONCLUSIONS For postmenopausal women with endometrial thickening, our results suggested that women who are older, have a thicker ET, had irregular menstruation in the past, have postmenopausal bleeding, and have polypoid mass-like lesions should seek medical attention as soon as possible and undergo further invasive examination. The use of 9.5 mm as the ET value to prompt investigations may be acceptable since it is unlikely to miss any atypical endometrial hyperplasia or endometrial cancer.

Li JXL, Chan F, Johansson CYM. Can a higher endometrial thickness threshold exclude endometrial cancer and atypical hyperplasia in asymptomatic postmenopausal women? A systematic review. Aust N Z J Obstet Gynaecol 2022; 62:190-197. [PMID: 34994399 DOI: 10.1111/ajo.13472] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Revised: 11/28/2021] [Accepted: 12/20/2021] [Indexed: 01/03/2023]
Abstract
BACKGROUND Asymptomatic postmenopausal women incidentally found to have thickened endometrium (>4 mm) on transvaginal ultrasound (TVUS) often undergo hysteroscopy and dilatation and curettage despite having a low absolute risk of endometrial cancer. A low threshold for investigation may be unnecessary in these women. AIM This systematic literature review examines whether an increased TVUS endometrial thickness threshold has superior diagnostic accuracy for endometrial malignancies and premalignancies in asymptomatic postmenopausal women than the current threshold of ≥4 mm. METHODS Pubmed, EMBASE and Cochrane Database of Systematic Reviews were systematically searched using keywords for publications between 2011 and 2021. Studies were included if they reported TVUS endometrial thickness analysis in asymptomatic postmenopausal women and excluded if they were written in a non-English language. Quality of evidence in the included articles was evaluated according to recommendations by the Grading of Recommendations Assessment Development and Evaluation Working Group and reported results were tabulated. RESULTS Of seven studies (N = 2986), better evidence identified 12 mm as the optimal diagnostic threshold (area under the curve receiver operating characteristic (AUC ROC) 0.716, 95% CI 0.534-0.897, P = 0.019) for endometrial cancer in asymptomatic postmenopausal women. Two higher quality studies (n = 488 and n = 4751) identified 11 mm as optimal for diagnosing both endometrial carcinoma and atypical hyperplasia (AUC ROC 0.587, 95% CI 0.465-0.708, P = 0.144 and 2.59 relative risk, 95% CI 1.66-4.05, P < 0.001). CONCLUSION Evidence for improved detection of endometrial premalignancies and malignancies using alternative endometrial thickness thresholds is not rigorous. Evidence for improved outcomes using alternative thresholds is inadequate. Observation of asymptomatic postmenopausal women without risk factors and with an endometrial thickness of less than 10 mm may be reasonable.

Abstract
The endometrium is a dynamic target organ in a woman's reproductive life. It undergoes cyclical change regulated by the fine balance between oestrogen and progesterone. The endometrial thickness (ET) varies according to the phases of the menstrual cycle. Endometrium contains both oestrogen and progesterone receptors, which respond to above hormones, irrespective of whether the woman is in reproductive or menopausal phase. Abundance of oestrogen leads to endometrial hyperplasia, and paucity causes endometrial atrophy. The initial best modality of assessing ET or aberration is high resolution transvaginal ultrasonogram. Thickened endometrium is always a clinical conundrum. Dilemma does remain as to the thickness of endometrium which requires intervention, mostly in symptomatic pre and perimenopausal women. In post-menopausal women with bleeding, the cut-off of ET that warrants investigation is almost defined. However, the cut-off value of ET in asymptomatic postmenopausal women; beyond which intervention is required, is still debated. Dilemma also exists about the cut-off of ET in both symptomatic and asymptomatic women on HRT and Tamoxifen. This article will discuss the above issues and reach at some consensus about the cut-off of ET after critical analysis of evidence and experience and will help clinicians in arriving at a proper decision in dealing with such clinically confounding situations.

Abstract
It has been suggested that impaired venous drainage and endometrial vascular ectasia (EMVE), secondary to increased intramural pressure, explains abnormal bleeding in fibroid uteri. Striking EMVE with extravasated red blood cells (ecchymosis) has also been seen in uteri with grossly obvious myometrial hyperplasia (MMH), suggesting that increased intramural pressure can cause EMVE in the absence of fibroids. EMVE with MMH may explain the century old association of clinically enlarged uteri with abnormal bleeding, and this same mechanism may be operative in myopathic uteri with grossly obvious adenomyosis. EMVE with associated thrombosis, ecchymosis, and/or stromal breakdown is commonly seen in random sections of hysterectomies for bleeding. EMVE may also be associated with endothelial hyperplasia, consistent with a reaction to endothelial injury due to impaired venous drainage. This further supports the theory that EMVE bleeds when thrombosis occurs, due to Virchow's Triad (stasis, endothelial injury, and hypercoagulability). EMVE may be "the lesion for which surgery was performed" in hysterectomies with otherwise unexplained bleeding.
