Abstract
AIM The effectiveness of hysteroscopy in diagnosing endometrial lesions has been demonstrated, showing high diagnostic accuracy for malignant endometrial lesions. Although the characteristic appearances of atypical and malignant endometria have been reported, they are not definitive and sometimes complicated. This study aimed to identify a small number of characteristic features to detect endometrial abnormalities using a simple judgment system and analyze the diagnostic characteristics and their accuracy in endometrial malignancy diagnosis. METHODS We performed a retrospective analysis of hysteroscopy video data of 250 patients, of which we selected for analysis based on pathology examination 152 cases with benign changes, 16 with atypical endometrium, and 18 with carcinoma in situ or endometrial cancer. Endometrial characteristics assessed included protrusion, desquamation, extended vessel, atypical vessel, and white/yellow lesion. RESULTS Multivariable analysis revealed that desquamation (p = 0.001, odds ratio [OR] 5.28), atypical vessels (p < 0.001, OR 8.50), and white/yellow lesions (p = 0.011, OR 1.37) were significant predictors for endometrial malignancy. From their contribution status, scoring points of 4, 6, and 1 were settled according to the odds ratio proportions. When scores ≥5 (at least both desquamation and white/yellow lesions or only atypical vessels) were used to define endometrial malignancy, sensitivity and specificity were 100% and 92%, respectively. When detecting cancer, atypical, and benign cases, sensitivity and specificity were 88% and 90%, respectively. CONCLUSION Our characteristics hysteroscopic findings showed a higher predictive ability in detecting endometrial malignancies. However, further examination with more cases would be needed to accurately diagnose endometrial malignancy by hysteroscopy.

Abstract
OBJECTIVE To identify predictive clinico-pathologic factors for concurrent endometrial carcinoma (EC) among patients with endometrial intraepithelial neoplasia (EIN) using machine learning. METHODS a retrospective analysis of 160 patients with a biopsy proven EIN. We analyzed the performance of multiple machine learning models (n = 48) with different parameters to predict the diagnosis of postoperative EC. The prediction variables included: parity, gestations, sampling method, endometrial thickness, age, body mass index, diabetes, hypertension, serum CA-125, preoperative histology and preoperative hormonal therapy. Python 'sklearn' library was used to train and test the models. The model performance was evaluated by sensitivity, specificity, PPV, NPV and AUC. Five iterations of internal cross-validation were performed, and the mean values were used to compare between the models. RESULTS Of the 160 women with a preoperative diagnosis of EIN, 37.5% (60) had a post-op diagnosis of EC. In univariable analysis, there were no significant predictors of EIN. For the five best machine learning models, all the models had a high specificity (71%-88%) and a low sensitivity (23%-51%). Logistic regression model had the highest specificity 88%, XG Boost had the highest sensitivity 51%, and the highest positive predictive value 62% and negative predictive value 73%. The highest area under the curve was achieved by the random forest model 0.646. CONCLUSIONS Even using the most elaborate AI algorithms, it is not possible currently to predict concurrent EC in women with a preoperative diagnosis of EIN. As women with EIN have a high risk of concurrent EC, there may be a value of surgical staging including sentinel lymph node evaluation, to more precisely direct adjuvant treatment in the event EC is identified on final pathology.

Abstract
BACKGROUND Fertility preservation treatment is increasingly essential for patients with apical endometrial hyperplasia (AEH) and early endometrial cancer (EEC) worldwide. Complete regression (CR) is the main endpoint of this treatment. Accurately predicting CR and implementing appropriate interventions during treatment are crucial for these patients. METHODS We conducted a retrospective study involving 193 patients diagnosed with atypical AEH or EEC, enrolled from January 2012 to March 2022 at our center. We evaluated 24 clinical parameters as candidate predictors and employed LASSO regression to develop a prediction model for CR. Subsequently, a nomogram was constructed to predict CR after the treatment. We evaluated the performance of the nomogram using receiver operator characteristic (ROC) curve and decision curve analysis (DCA) to assess its predictive accuracy. Additionally, we employed cumulative curves to determine the CR rate among patients. RESULTS Out of the 193 patients, 173 achieved CR after undergoing fertility preservation treatment. We categorized features with similar properties and provided a list of formulas based on their coefficients. The final model, named GLOBAL (including basic information, characteristics, blood pressure, glucose metabolism, lipid metabolism, immunohistochemistry, histological type, and medication), comprised eight variables identified using LASSO regression. A nomogram incorporating these eight risk factors was developed to predict CR. The GLOBAL model exhibited an AUC of 0.907 (95% CI 0.828-0.969). Calibration plots demonstrated a favorable agreement between the predicted probability by the GLOBAL model and actual observations in the cohort. The cumulative curve analysis revealed varying cumulative CR rates among patients in the eight subgroups. Categorized analysis demonstrated significant diversity in the effects of the GLOBAL model on CR among patients with different total points (p < 0.05). CONCLUSION We have developed and validated a model that significantly enhances the predictive accuracy of CR in AEH and EEC patients seeking fertility preservation treatment.

Abstract
BACKGROUND Endometrial hyperplasia (EH) is a precusor lesion for endometrial cancer (EC), the commonest gynaecological malignancy in high-income countries. EH is a proliferation of glandular tissue, classified as either non-atypical endometrial hyperplasia (NEH) or, if the cytological features are abnormal, atypical endometrial hyperplasia (AEH). The clinical significance of AEH is that patients face both a high risk of having occult EC and a high risk of progression to EC if untreated. Recommendations on the care of women with EH were introduced by United Kingdom-wide guidance (Green-top Guide No. 67, 2016). National adherence to guidance is unknown. We aimed to describe the care of patients with EH; to compare the patterns of care for those with EH with national guidance to identify opportunities for quality improvement; and to compare patterns of care prior to and following the introduction of national guidance to understand its impact. METHODS AND FINDINGS In this UK-wide patient-level clinical audit, we included 3,307 women who received a new histological diagnosis of EH through a gynaecology service between 1 January 2012 and 30 June 2020. We described first-line management, management at 2 years, and surgical characteristics prior to and following national guidance for EH using proportions and 95% confidence intervals (CIs) and compared process measures between time periods using multilevel Poisson regression. Of the 3,307 patients, 1,570 had NEH and 1,511 had AEH between 2012 and 2019. An additional 85 patients had NEH and 141 had AEH during 2020. Prior to national guidance, 9% (95% CI [6%, 15%]) received no initial treatment for NEH compared with 3% (95% CI [1%, 5%]) post-guidance; 31% (95% CI [26%, 36%]) and 48% (95% CI [43% 53%]) received an intrauterine progestogen, respectively, in the same periods. The predominant management of women with AEH did not differ, with 68% (95% CI [61%, 74%]) and 67% (95 CI [63%, 71%]) receiving first-line hysterectomy, respectively. By 2 years, follow-up to histological regression without hysterectomy increased from 38% (95% CI [33%, 43%]) to 52% (95% CI [47%, 58%]) for those with NEH (rate ratio (RR) 1.38, 95% CI [1.18, 1.63] p < 0.001). We observed an increase in the use of total laparoscopic hysterectomy among those with AEH (RR 1.26, 95% CI [1.04, 1.52]). In the later period, 37% (95% CI [29%, 44%]) of women initially diagnosed with AEH who underwent a first-line hysterectomy, received an upgraded diagnosis of EC. Study limitations included retrospective data collection from routine clinical documentation and the inability to comprehensively understand the shared decision-making process where care differed from guidance. CONCLUSIONS The care of patients with EH has changed in accordance with national guidance. More women received first-line medical management of NEH and were followed up to histological regression. The follow-up of those with AEH who do not undergo hysterectomy must be improved, given their very high risk of coexistent cancer and high risk of developing cancer.

Abstract
BACKGROUND Demographic features, suggestive gynaecological symptoms, and immunohistochemical expression of endometrial β-catenin have a prognostic capacity for endometrial hyperplasia and carcinoma. This study assessed the interaction of all variables and developed risk stratification for endometrial hyperplasia and carcinoma. METHODS This cross-sectional study was conducted from January 2023 to July 2023 at two teaching hospitals in Makassar Indonesia. Patients (< 70 years old) with suggestive symptoms of endometrial hyperplasia or carcinoma or being referred with disease code N.85 who underwent curettage and/or surgery for pathology assessment except those receiving radiotherapy, or chemotherapy, presence of another carcinoma, coagulation disorder, and history of anti-inflammatory drug use and unreadable samples. Demographic, and clinical symptoms were collected from medical records. Immunohistochemistry staining using mouse-monoclonal antibodies determined the β-catenin expression (percentage, intensity, and H-score) in endometrial tissues. Ordinal and Binary Logistic regression identified the potential predictors to be included in neural networks and decision tree models of histopathological grading according to the World Health Organization/WHO grading classification. RESULTS Abdominal enlargement was associated with worse pathological grading (adjusted odds ratio/aOR 6.7 95% CI 1.8-24.8). Increasing age (aOR 1.1 95% CI 1.03-1.2) and uterus bleeding (aOR 5.3 95% CI 1.3-21.6) were associated with carcinoma but not with %β-catenin and H-Score. However, adjusted by vaginal bleeding and body mass index, lower %β-catenin (aOR 1.03 95% 1.01-1.05) was associated with non-atypical hyperplasia, as well as H-Score (aOR 1.01 95% CI 1.01-1.02). Neural networks and Decision tree risk stratification showed a sensitivity of 80-94.8% and a specificity of 40.6-60% in differentiating non-atypical from atypical and carcinoma. A cutoff of 55% β-catenin area and H-Score of 110, along with other predictors could distinguish non-atypical samples from atypical and carcinoma. CONCLUSION Risk stratification based on demographics, clinical symptoms, and β-catenin possesses a good performance in differentiating non-atypical hyperplasia with later stages.

Abstract
PURPOSE To evaluate the rate of atypical hyperplasia (AH) underestimating endometrial cancer (EC) comparing endometrial biopsy (EB) accomplished by hysteroscopic biopsy with dilatation and curettage (D&C). Second, to compare the two techniques to foresee EC grading. METHODS This trial was based on the findings of two Gynecological Departments within the same Public Utility, sharing pathological service and database but routinely performing EB under hysteroscopic visualization (group A) or hysteroscopy followed by D&C (group B). We retrieved the clinical data of patients showing EC on hysterectomy throughout a 10-year period. The accuracy of hysteroscopic-view diagnosis and EB pathology were compared, having the pathologic findings of hysterectomy as reference. RESULTS A total of 161 patients met the inclusion criteria. Among these, 109 and 52 were included in groups A and B, respectively. In group A, 32.1% of patients underwent EB in an out-patient setting. To foresee EC, hysteroscopic view showed a sensitivity of 82.5% and 70.2% in groups A and B, respectively (P = 0.019). An underestimation of EC diagnosed as AH on EB was found in 20 patients (12.4%). Among these, 18 (16.5%) and 2 (3.8%) were included in groups A and B, respectively (P = 0.022). In group A, a fault diagnosis of AH resulted higher when EB was performed as out-patient setting (P = 0.006). EB allowed the grading of EC in 73.3% and 90.3% of patients in groups A and B, respectively. The agreement was 73.7% and 85.1%, leading to moderate (κ = 0.56) and good (κ = 0.77) "κ" coefficient of concordance for groups A and B, respectively. CONCLUSIONS EB performed by D&C lowers the rate of AH underestimating concurrent EC and improves the grading agreement when compared with hysteroscopic sampling.

Abstract
The diagnosis of atypical hyperplasia/endometrioid intraepithelial neoplasm (AH/EIN) within endometrial polyps (EMPs) often poses a diagnostic conundrum. Our previous studies demonstrated that a panel of immunohistochemical (IHC) markers consisting of PAX2, PTEN, and β-catenin can be effectively utilized for the identification of AH/EIN. A total of 105 AH/EIN within EMP were analyzed using the 3-marker panel. We also evaluated these cases for the presence of morules. Benign EMP (n=90) and AH/EIN unassociated with polyp (n=111) served as controls. Aberrant expression of PAX2, PTEN, or β-catenin was observed in AH/EIN in EMP in 64.8%, 39.0%, and 61.9% of cases, respectively. At least 1 IHC marker was abnormal in 92.4% of cases. Overall, 60% of AH/EIN in EMP demonstrated abnormal results for≥2 IHC markers. The prevalence of PAX2 aberrancy was significantly lower in AH/EIN in EMP than in nonpolyp AH/EIN (64.8% vs. 81.1%, P =0.007), but higher than in benign EMP (64.8% vs. 14.4%, P <0.00001). The prevalence of β-catenin aberrancy was significantly higher in AH/EIN in EMP than in nonpolyp AH/EIN (61.9% vs. 47.7%, P =0.037). All control benign EMP demonstrated normal expression of PTEN and β-catenin. Morules were present in 38.1% of AH/EIN in EMP versus 24.3% in nonpolyp AH/EIN, and absent in benign EMP. A strong positive association was found between β-catenin and morules (Φ=0.64). Overall, 90% cases of atypical polypoid adenomyoma (n=6) and mucinous papillary proliferation (n=4) showed IHC marker aberrancy. In conclusion, the 3-marker IHC panel (PAX2, PTEN, and β-catenin) is (1) a useful tool in the diagnosis of AH/EIN in EMP; (2) PAX2 loss should be interpreted with caution and in combination with morphology and other markers.

Abstract
SUMMARY Endometrial intraepithelial neoplasia (EIN) or atypical endometrial hyperplasia (AEH) often is a precursor lesion to adenocarcinoma of the endometrium. Hysterectomy is the definitive treatment for EIN-AEH. When a conservative (fertility-sparing) approach to the management of EIN-AEH is under consideration, it is important to attempt to exclude the presence of endometrial cancer to avoid potential undertreatment of an unknown malignancy in those who have been already diagnosed with EIN-AEH. Given the high risk of progression to cancer, those who do not have surgery require progestin therapy (oral, intrauterine, or combined) and close surveillance. Although data are conflicting and limited, studies have demonstrated that treatment with the levonorgestrel-releasing intrauterine device results in a higher regression rate when compared with treatment with oral progestins alone. Limited data suggest that cyclic progestational agents have lower regression rates when compared with continuous oral therapy. After initial conservative treatment for EIN-AEH, early detection of disease persistence, progression, or recurrence requires careful follow-up. Gynecologists and other clinicians should counsel patients that lifestyle modification resulting in weight loss and glycemic control can improve overall health and may decrease the risk of EIN-AEH and endometrial cancer.

Abstract
OBJECTIVE To evaluate the contribution of PAX2, ARID1A, and FOXA1 biomarkers to diagnosis in cases with atypical endometrial hyperplasia (AEH). STUDY DESIGN Descriptive Study. Place and Duration of the Study: Pathology Department of Umraniye Training and Research Hospital, from January 2018 to December 2020. METHODOLOGY Curettage materials of 100 patients diagnosed with AEH which stained PAX2, ARID1A, and FOXA1, were evaluated. The staining patterns in the atypical endometrial glandular areas were grouped as slight-no loss, moderate loss, and complete loss / severe loss for all three biomarkers. Complete or/severe loss in AEH was considered helpful in the diagnosis. RESULTS Complete loss / severe loss rates in curettages were 84% for PAX2, 5% for ARID1A, and 15% for FOXA1, respectively. When used in combination, complete loss / severe loss rates were 85% in at least one of the three markers, 84% in PAX2 and/or ARID1A, 85% in PAX2 and/or FOXA1, and 17% in ARID1A and/or FOXA1. CONCLUSION Although all 3 biomarkers showed marked staining loss, PAX2 is the most sensitive biomarker for the diagnosis of AEH in curettage materials. KEY WORDS Endometrium, Atypical hyperplasia, PAX2, ARID1A, FOXA1.

Abstract
OBJECTIVE Elevated body mass index (BMI) is a risk factor for endometrioid endometrial cancer and its precursor, endometrial intraepithelial neoplasia (EIN). Our objective was to describe the association between BMI and age at EIN diagnosis. METHODS We conducted a retrospective study of patients diagnosed with EIN from 2010 to 2020 at a large academic medical center. Patient characteristics were stratified by menopausal status and compared using a chi-square or t-test. We used linear regression to determine the parameter estimate (β) and 95% confidence interval for the association between BMI and age at diagnosis. RESULTS We identified 513 patients with EIN; 503 (98%) had complete medical records. Premenopausal patients were more likely to be nulliparous and to have polycystic ovary syndrome than postmenopausal patients (both p ≤ 0.001). Postmenopausal patients were more likely to have hypertension, type 2 diabetes, and hyperlipidemia (all p ≤ 0.02). There was a significant linear association between BMI and age at diagnosis in premenopausal patients (β = -0.19 (95% CI: -0.27, -0.10). In premenopausal patients, for every 1-unit increase in BMI, age at diagnosis decreased by 0.19 years. No association was observed in postmenopausal patients. CONCLUSIONS In a large cohort of patients with EIN, increasing BMI was associated with an earlier age at diagnosis in premenopausal patients. This data suggests consideration of endometrial sampling in younger patients with known risk factors for excess estrogen exposure.

Abstract
BACKGROUND An increasing number of atypical endometrial hyperplasia (AEH) or endometrial cancer (EC) patients with fertility requirements choose conservative management, such as oral high-dose progesterone. Most of them use assisted reproductive technology (ART) to become pregnant after experiencing remission. However, the outcome of pregnancy is not ideal, probably because of long-term drug application in large doses or invasive uterine cavity treatment. CASE REPORT We presented a case of AEH who underwent direct pregnancy with good results without any treatment for her pathological endometrium. We described her endometrial histological results pre-and post-pregnancy in detail, hitherto absent from reports on this topic. CONCLUSIONS Patients with a strong desire to bear children at the time of an AEH diagnosis could consider taking 1-2 years to try a pregnancy before treating their AEH.

Abstract
PURPOSE This study aimed to identify the risk factors and sonographic variables that could be integrated into a predictive model for endometrial cancer (EC) and atypical endometrial hyperplasia (AEH) in women with abnormal uterine bleeding (AUB). MATERIALS AND METHODS This retrospective study included 1837 patients who presented with AUB and underwent endometrial sampling. Multivariable logistic regression was developed based on clinical and sonographic covariates [endometrial thickness (ET), resistance index (RI) of the endometrial vasculature] assessed for their association with EC/AEH in the development group (n=1369), and a predictive nomogram was proposed. The model was validated in 468 patients. RESULTS Histological examination revealed 167 patients (12.2%) with EC or AEH in the development group. Using multivariable logistic regression, the following variables were incorporated in the prediction of endometrial malignancy: metabolic diseases [odds ratio (OR)=7.764, 95% confidence intervals (CI) 5.042-11.955], family history (OR=3.555, 95% CI 1.055-11.971), age ≥40 years (OR=3.195, 95% CI 1.878-5.435), RI ≤0.5 (OR=8.733, 95% CI 4.311-17.692), and ET ≥10 mm (OR=8.479, 95% CI 5.440-13.216). A nomogram was created using these five variables with an area under the curve of 0.837 (95% CI 0.800-0.874). The calibration curve showed good agreement between the observed and predicted occurrences. For the validation group, the model provided acceptable discrimination and calibration. CONCLUSION The proposed nomogram model showed moderate prediction accuracy in the differentiation between benign and malignant endometrial lesions among women with AUB.

Abstract
BACKGROUND Abnormal uterine bleeding is a common cause of hospital admission in perimenopausal women. It can be the first sign of many diseases such as endometrial cancer and endometrial hyperplasia. Endometrial sampling is valuable in early diagnosis and treatment. Although hysterectomy is the gold standard in the diagnosis of endometrial pathology, it is not considered an acceptable method for diagnosis. With the principle of "see and treat, hysteroscopy seems to be the most successful method. METHODS After obtaining the necessary ethics committee approval, we obtained liquid-based cytology samples of our perimenopausal patients who frequently applied to our outpatient clinic with abnormal uterine bleeding. To conduct endometrial sampling of our patients, we used pipelle aspiration method in our 75-disease group and direct hysteroscopic sampling method in our other 75 disease group. We then compared the pre- and postoperative pathology results. RESULTS There was no statistically significant difference between preoperative and postoperative pathological results in both pipelle and hysteroscopic sampling groups. CONCLUSIONS Evaluation of endometrial pathologies by hysteroscopic method and pipelle method has high sensitivity and specificity. Gynecologists may determine the method preference according to the status of the health system together with their patients.

Abstract
OBJECTIVE This study aimed to evaluate risk factors for endometrial intraepithelial neoplasia/malignancy in premenopausal women with abnormal uterine bleeding or oligomenorrhea. Specifically, we aimed to elucidate whether body mass index (BMI) or age confers a higher risk. STUDY DESIGN A retrospective cohort study was performed at a large academic center examining risk factors for endometrial hyperplasia/malignancy in premenopausal women undergoing endometrial sampling. RESULTS Of the 4170 women ages 18-51 who underwent endometrial sampling from 1987 to 2019, 77 (1.85%) were found to have endometrial intraepithelial neoplasia or malignancy. Clinical predictors of EIN/malignancy in this population included obesity (OR: 3.84, 95%, p < .001), Body mass index [(OR30 vs. 25:2.11, p < .001) and OR35 vs. 30: 1.65, p < .001], Diabetes (OR: 3.6, p-value <.001), hormonal therapy use (OR: 2.93, p < .001), personal history of colon cancer (OR: 9.90, p = .003), family history of breast cancer (OR: 2.65, p < .001), family history of colon cancer (OR: 3.81, p < .001), and family history of endometrial cancer (OR: 4.92, p = .033). Age was not significantly associated with an increased risk of disease. Adjusting for other factors, a model using BMI to predict the risk of EIN/malignancy was more discriminative than a model based on age. CONCLUSIONS Increased BMI, may be more predictive of endometrial hyperplasia/malignancy than age in premenopausal women with abnormal uterine bleeding. Modification of evaluation guidelines in a contemporary demographic setting could be considered.

Abstract
INTRODUCTION In Japan, endometrial cytology is widely performed to evaluate the status of the endometrium in women with suspected endometrial cancer. A new classification system for endometrial cytology has recently been used: the Yokohama system, based on a descriptive reporting format. This study aimed to clarify the triage for patients with atypical endometrial cells of undetermined significance (ATEC-US) when followed by negative endometrial cytology. METHODS We enrolled patients diagnosed with ATEC-US at the Cancer Institute Hospital between January 2016 and December 2017, based on the following inclusion criteria: (1) ATEC-US diagnosed by office endometrial cytology, with or without office endometrial biopsy; (2) follow-up endometrial cytology was performed 3-6 months after initial sampling, with a negative result for malignancy; and (3) no prior history of conservative treatment with progestin for endometrial cancer or atypical endometrial hyperplasia (ATEC-A). Among eligible patients, we analyzed those later diagnosed by endometrial biopsy with ATEC-A or carcinoma. RESULTS Among 187 patients, 65 met the inclusion criteria. Forty-two patients (64.6%) were observed for more than 24 months. Two patients (3.1%) developed ATEC-A during a median observation time of 26.5 months; the times to diagnosis were 32 months and 22 months. DISCUSSION/CONCLUSION No patient developed ATEC-A or worse within 1 year. For patients with ATEC-US, if negative cytology is obtained at the next examination, a close follow-up is not necessary.

Abstract
The diagnosis of endometrial atypical hyperplasia/endometrioid intraepithelial neoplasia (AH/EIN) remains challenging and subjective in some cases, with variable histologic criteria and differences of opinion among gynecologic pathologists, potentially leading to under/overtreatment. There has been growing interest in the use of specific immunohistochemical markers as adjuncts in AH/EIN diagnosis. For example, the World Health Organization 2020 Classification specifies that loss of Pten, Pax2, or mismatch repair proteins are desirable diagnostic criteria. Other markers, most notably β-catenin and Arid1a, are also aberrantly expressed in some AH/EIN. However, the performance of some markers individually-and more importantly as a group-has not been rigorously explored, raising questions as to which marker(s) or combination(s) is the most effective in practice. Formalin-fixed paraffin-embedded tissue sections from AH/EIN cases (n=111) were analyzed by immunohistochemistry for 6 markers: Pax2, Pten, Mlh1, β-catenin, Arid1a, and p53. Aberrant expression was tabulated for each case and marker. An additional set of normal endometria (n=79) was also analyzed to define optimal diagnostic criteria for marker aberrance. The performance characteristics of each marker, the entire panel, and subsets thereof were quantitatively and statistically analyzed. In order of number of cases detected, the most frequently aberrant markers in AH/EIN were Pax2 (81.1% of cases), Pten (50.5%), β-catenin (47.7%), Arid1a (7.2%), Mlh1 (4.5%), and p53 (2.7%). The majority of cases showed aberrant expression of ≥2 markers. All 6 markers together identified 92.8% of cases. Arid1a, Mlh1, and p53 were robust and readily scored markers, but all cases showing aberrant expression of these 3 markers were also detected by Pax2, Pten, or β-catenin. A focused panel of only 3 markers (Pax2, Pten, and β-catenin) showed optimal performance characteristics as a diagnostic adjunct in the histopathologic diagnosis of AH/EIN. Use of this panel is practicable and robust, with at least 1 of the 3 markers being aberrant in 92.8% of AH/EIN.

Abstract
Histologic assessment of response to progestogen therapy is a cornerstone of nonsurgical management of atypical hyperplasia/low-grade endometrioid carcinoma. Pathologists are required to assess whether there is ongoing preneoplastic or neoplastic change in the biopsies (often multiple) taken during therapy. There have been few studies documenting the specific histologic changes induced by therapeutic progestogens and currently there are no guidelines on terminology used in this scenario. Given the need for uniformity in reporting and the lack of guidance in the current literature, we initiated an online survey (including questions, categories of reporting, and scanned slides for assessment) which was sent to all members of British Association of Gynaecological Pathologists (BAGP) and the International Society of Gynecological Pathologists (ISGyP) with the aim to assess the variability among pathologists in reporting these specimens and to come up with a consensus-based terminology for reporting of endometrial biopsies from women on progestogen therapy for endometrial atypical hyperplasia/endometrioid carcinoma. In total, 95 pathologists participated in this survey. This manuscript elaborates on the results of the survey with recommendations aimed at promoting uniform terminology in reporting these biopsies.

Abstract
In the United Kingdom, endometrial biopsy reports traditionally consist of a morphologic description followed by a conclusion. Recently published consensus guidelines for reporting benign endometrial biopsies advocate the use of standardized terminology. In this project we aimed to assess the acceptability and benefits of this simplified "diagnosis only" format for reporting non-neoplastic endometrial biopsies. Two consultants reported consecutive endometrial biopsies using 1 of 3 possible formats: (i) diagnosis only, (ii) diagnosis plus an accompanying comment, and (iii) the traditional descriptive format. Service users were asked to provide feedback on this approach via an anonymized online survey. The reproducibility of this system was assessed on a set of 53 endometrial biopsies among consultants and senior histopathology trainees. Of 370 consecutive benign endometrial biopsies, 245 (66%) were reported as diagnosis only, 101 (27%) as diagnosis plus a brief comment, and 24 (7%) as diagnosis following a morphologic description. Of the 43 survey respondents (28 gynecologists, 11 pathologists, and 4 clinical nurse specialists), 40 (93%) preferred a diagnosis only, with 3 (7%) being against/uncertain about a diagnosis only report. Among 3 histopathology consultants and 4 senior trainees there was majority agreement on the reporting format in 53/53 (100%) and 52/53 (98%) biopsies. In summary, we found that reporting benign specimens within standardized, well-understood diagnostic categories is an acceptable alternative to traditional descriptive reporting, with the latter reserved for the minority of cases that do not fit into specific categories. This revised approach has the potential to improve reporting uniformity and reproducibility.

Abstract
Background and Objectives: Endometrial hyperplasia (EH) is a precursor lesion to endometrial cancer (EC), and when cellular atypia is present, in 40% of cases, they are diagnosed with EC on hysterectomy. Usually, EH is clinically manifested by uterine bleeding. In patients with oral anticoagulant therapy (OAT), the uterus is the second most common source of bleeding. The aim of the study was to show that uterine bleeding in postmenopausal patients undergoing OAT may reveal precancerous endometrial lesions with atypia, or neoplastic lesions in patients with an initial diagnosis of endometrial hyperplasia without atypia (non-atypical endometrial hyperplasia, NAEH) on dilation and curettage (D&C). We will be able to estimate the risk of a postmenopausal female patient with uterine bleeding during an OAT to have a precancerous endometrial lesion. Materials and Methods: The subjects of the study were 173 female patients with uterine bleeding, who have had total hysterectomy with bilateral salpingoovarectomy, of whom 99 underwent an OAT. There were 101 female patients initially diagnosed with NAEH, of which 60 did not have anticoagulant treatment (mean age 57.36 ± 6.51) and 41 had anticoagulant treatment (mean age 60.39 ± 7.35) (p = 0.006). From the pathology diagnosis moment, the surgery was performed at 42.09 ± 14.54 days in patients without OAT and after 35.39 ± 11.29 days in those who received such treatment (p = 0.724). Results: Initial diagnosis of NAEH established at D&C was changed at the final diagnosis after hysterectomy in EH with cellular atypia (atypical endometrial hyperplasia AEH) or EC in 18.18% of patients without OAT, and in 40.54% of patients who received this treatment. Conclusions: Based on a logistic regression model, it is estimated that female patients with an initial histopathological diagnosis of NAEH and who underwent OAT have, on average, 4.85 times greater odds (OR = 4.85, 95% CI 1.79–14.06) than the others of being identified postoperatively with more advanced lesions.

Abstract
A subtle 'burrowing' pattern of cervical stromal involvement by low-grade endometrioid adenocarcinoma of the uterine corpus is described in the literature. We report a small case series in which this pattern of cervical stromal involvement, warranting a diagnosis of endometrioid adenocarcinoma in the cervix, occurred in association with sometimes subtle endometrioid proliferations within the endometrium which fall short of the criteria for endometrioid adenocarcinoma and are in keeping with atypical hyperplasia or hyperplasia without atypia. In reporting this phenomenon, which has not been described previously, we highlight the importance of immunohistochemistry in the differential diagnosis, particularly in the exclusion of primary cervical glandular lesions, including those of mesonephric type. We discuss the differential with primary endometrioid adenocarcinoma (including minimal deviation type) of the cervix and other lesions and stress the importance of sampling the endometrium and lower uterine segment in their entirety in order to exclude an atypical hyperplasia or an adenocarcinoma in these locations. Although the pathogenesis of the cervical lesion we report is controversial, we believe that it is most likely a result of spread from the endometrium and results in the unusual occurrence of the malignant nature of the lesion being only apparent in the secondary rather than the primary lesion. We provide recommendations for reporting such cases and recommend designating them as stage II endometrial carcinoma, although the prognostic and management implications of such cases will only be clear once further cases with follow-up are reported.

Abstract
Endometrial cancer is a ubiquitous gynecological disease with increasing global incidence. Therefore, despite the lack of an established screening technique to date, early diagnosis of endometrial cancer assumes critical importance. This paper presents an artificial-intelligence-based system to detect the regions affected by endometrial cancer automatically from hysteroscopic images. In this study, 177 patients (60 with normal endometrium, 21 with uterine myoma, 60 with endometrial polyp, 15 with atypical endometrial hyperplasia, and 21 with endometrial cancer) with a history of hysteroscopy were recruited. Machine-learning techniques based on three popular deep neural network models were employed, and a continuity-analysis method was developed to enhance the accuracy of cancer diagnosis. Finally, we investigated if the accuracy could be improved by combining all the trained models. The results reveal that the diagnosis accuracy was approximately 80% (78.91–80.93%) when using the standard method, and it increased to 89% (83.94–89.13%) and exceeded 90% (i.e., 90.29%) when employing the proposed continuity analysis and combining the three neural networks, respectively. The corresponding sensitivity and specificity equaled 91.66% and 89.36%, respectively. These findings demonstrate the proposed method to be sufficient to facilitate timely diagnosis of endometrial cancer in the near future.

Abstract
OBJECTIVE The weak estrogenic-like effect of selective estrogen receptor modulator (SERM) may lead to series of endometrial lesions, including proliferation, hyperplasia, polyp formation, and even endometrial cancer. This study aimed to explore the effectiveness of different endometrial thickness in diagnosis of endometrial hyperplasia during SERM therapy in premenopausal patients. METHODS The clinical data of 115 patients receiving hysteroscopic endometrial biopsy during SERM therapy in Peking Union Medical College Hospital, China from January 2010 to December 2018 were retrospectively analyzed. RESULTS Average age at the beginning of SERM therapy was 43.4 ± 5.7 years old. Mean duration time of SERM therapy was 31.0 ± 22.1 months. The mean endometrial thickness was 14.3 ± 6.1 mm. 4 cases of atypical endometrial hyperplasia (3.5 %), and 4 cases of endometrial hyperplasia without atypia (3.5 %) were detected. Endometrial thickness was higher in endometrial hyperplasia patients than in no endometrial hyperplasia patients (18.8 vs 13.9 mm, p = 0.029). Endometrial thickness in 8 out of 8 endometrial hyperplasia patients and 38 out of 107 no endometrial hyperplasia patients were ≥ 15 mm (p = 0.002). The negative predictive value in the diagnosis of endometrial hyperplasia during SERM therapy in premenopausal patients was 100 % when endometrial thickness < 15 mm chosen as cutoff value. CONCLUSION Endometrial hyperplasia was less likely to occur in premenopausal patients during SERM therapy when endometrial thickness < 15 mm.

Abstract
STUDY OBJECTIVE To examine the diagnostic accuracy of hysteroscopic photodynamic diagnosis (PDD) using 5-aminolevulinic acid (5ALA) in patients with endometrial cancer and premalignant atypical endometrial hyperplasia. DESIGN A single-center, open-label, exploratory intervention study. SETTING University Hospital in Japan. PATIENTS Thirty-four patients who underwent hysteroscopic resection in the Department of Obstetrics and Gynecology at Keio University Hospital. INTERVENTIONS Patients were given 5ALA orally approximately 3 hours before surgery and underwent observation of the uterine cavity and endometrial biopsy using 5ALA-PDD during hysteroscopic resection. Specimens were diagnosed histopathologically and the diagnostic sensitivity and specificity of hysteroscopic 5ALA-PDD for malignancy in the uterine cavity was determined. Red (R), blue (B), and green (G) intensity values were determined from PDD images, and the relationships of histopathological diagnosis with these values were used to develop a model for objective diagnosis of uterine malignancy. MEASUREMENTS AND MAIN RESULTS Three patients were excluded from the study because of failure of the endoscope system. A total of 113 specimens were collected endoscopically. The sensitivity and specificity of 5ALA-PDD for diagnosis of malignancy in the uterine cavity were 93.8% and 51.9%, respectively. The R/B ratio in imaging analysis was highest in malignant lesions, followed by benign lesions and normal uterine tissue, with significant differences among these groups (p <.05). The R/B and G/B ratios were used in a formula for prediction of malignancy based on logistic regression and the area under the receiver operating characteristic curve for this formula was 0.838. At a formula cutoff value of 0.220, the sensitivity and specificity for diagnosis of malignant disease were 90.6% and 65.4%, respectively. CONCLUSION To our knowledge, this is the first study of the diagnostic accuracy of 5ALA-PDD for malignancies in the uterine cavity. Hysteroscopic 5ALA-PDD had higher sensitivity and identifiability of lesions. These findings suggest that hysteroscopic 5ALA-PDD may be useful for diagnosis of minute lesions.

Abstract
BACKGROUND To inform treatment decisions in women diagnosed with endometrial hyperplasia, quantification of the potential for concurrent endometrial cancer and the future risk of progression to cancer is required. METHODS We identified studies up to September 2018 that reported on the prevalence of concurrent cancer (within three months of endometrial hyperplasia diagnosis), or the incidence of cancer, identified at least three months after hyperplasia diagnosis. Random-effects meta-analyses produced pooled estimates and 95% confidence intervals (CIs). RESULTS A total of 36 articles were identified; 15 investigating concurrent and 21 progression to cancer. In pooled analysis of 11 studies of atypical hyperplasia, the pooled prevalence of concurrent endometrial cancer was 32.6% (95% CI: 24.1%, 42.4%) while no studies evaluated concurrent cancer in non-atypical hyperplasia. The risk of progression to cancer was high in atypical hyperplasia (n = 5 studies, annual incidence rate = 8.2%, 95% CI 3.9%, 17.3%) and only one study reported on non-atypical hyperplasia (annual incidence rate = 2.6%, 95% CI: 0.6%, 10.6%). CONCLUSIONS Overall, a third of women with atypical hyperplasia had concurrent endometrial cancer, although the number of studies, especially population-based, is small. Progression to cancer in atypical hyperplasia was high, but few studies were identified. Population-based estimates are required, in both atypical and non-atypical hyperplasia patients to better inform treatment strategies.

Abstract
Objectives: Abnormal uterine bleeding (AUB) is a leading cause of hysterectomies, the cause of which is usually diagnosed with preoperative endometrial sampling. We planned this study to assess the accuracy of diagnosing the histologic patterns of endometrium in the preoperative sample in reference to the final histologic diagnosis in hysterectomy. Methods: We retrospectively reviewed medical charts between January 2011 and December 2015 at a tertiary hospital in Saudi Arabia and identified 43 cases of AUB with complete documentation. The histologic diagnoses were classified into normal and benign pathology group (N/B), or carcinoma and hyperplasia category (Ca/H). Measures of validity were used to compare endometrial sampling histological diagnoses to diagnoses following hysterectomy and Cohen’s kappa to assess for agreement between the 2 modalities. Results: The median age of all patients was 49 years. Preoperative histologic examination showed 53.8% sensitivity, 90% specificity, 70% positive predictive values and 81.8% negative predictive values, 30.1% false positive rates and 18.2% false negative rates. The agreement between preoperative and postoperative histologic diagnoses was moderate (79.1%, k=0.469). Conclusion: The accuracy of preoperative histologic examination was moderate. Our findings recommend cautious clinical decision making and limiting hysterectomy to women who do not respond to other therapeutic measures.

Abstract
Outpatient endometrial biopsy can give false-negative results, with a 0.9% reported posttest probability for endometrial carcinoma (EC) after a negative result. Our objective was to determine if there has been any improvement in the performance characteristics of endometrial biopsy over the last 15 yr. All hysterectomy specimens with a diagnosis of EC or atypical hyperplasia (AH), reported between May 2011 and May 2015, were identified and cross-referenced for any negative endometrial sampling results during the 5 yr before hysterectomy. Negative endometrial samples were defined as either benign findings or insufficient/nondiagnostic, excluding those diagnosed as AH or EC and those for which follow-up sampling was recommended because of atypia. Of 1677 hysterectomy specimens showing AH or EC there were previous negative biopsies in 172: 116 benign and 56 insufficient/nondiagnostic. Over the same period 22,875 negative endometrial biopsy specimens were reported in our region. The posttest probability of having EC or AH in the hysterectomy specimen, given a negative endometrial biopsy result, was 0.74%. In a subset of 90 cases in which a negative biopsy was followed by a diagnosis of AH or EC in a hysterectomy specimen, the slides were independently reviewed. There were no cases where a diagnosis of carcinoma was missed. In 12 samples atypia or possible atypia was identified, and the level of agreement with the original diagnosis was excellent κ=0.83±0.05. In a prospective comparison of examination of 3 levels from each block versus a single slide in 319 cases, the routine preparation of additional slides did not yield clinically significant information. Although there has been evolution in the diagnostic criteria for AH and for recognition of morphologically subtle forms of AH or EC, our results demonstrate a significant lack of sensitivity of outpatient endometrial sampling in the diagnosis of endometrial malignancy/premalignancy. The sensitivity problems are mainly attributable to failure to sample abnormal endometrium. Independent review of slides or examination of additional levels did little to increase the diagnostic yield.

Abstract
STUDY OBJECTIVE To evaluate characteristics of young women with endometrial hyperplasia or cancer. DESIGN Retrospective chart review. SETTING Tertiary care referral center. PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES We included 10- to 25-year-old young women seen at a single institution between 2006 and 2017 with International Classification of Diseases 9th and 10th revision codes for endometrial cancer or hyperplasia (cases), or who underwent an endometrial biopsy with other benign pathologic diagnoses (controls). Exclusions included a diagnosis of Lynch syndrome. Comparisons were made using χ2, Fisher exact, and nonparametric Wilcoxon rank tests. RESULTS Sixty-nine patients were identified: 13 cases, 54 controls, and 2 exclusions. Of the 13 cases, 3 had endometrial cancer, 5 had complex atypical hyperplasia (now called endometrioid intraepithelial neoplasia), and 5 had hyperplasia without atypia. A higher proportion of cases had a body mass index (BMI) greater than 30, compared with controls (76.9% vs 40.4%; P < .03). The proportion of patients who had a BMI greater than 30 and were smokers was significantly higher among cases (38.5% vs 9.3%; P < .02). The proportion of patients with a history of polycystic ovary syndrome (PCOS) and smoking was also significantly different between groups (30.8% vs 3.7%; P < .01). CONCLUSION In women aged 25 years and younger with endometrial sampling, a BMI greater than 30 was statistically more common in patients with endometrioid intraepithelial neoplasia or cancer. Although smoking or PCOS alone was not related to endometrial hyperplasia or cancer in this small cohort study, there might be a relationship between endometrial abnormalities and multiple exposures, including smoking and BMI greater than 30 or smoking and a history of PCOS.

Abstract
BACKGROUND One million women per year seek medical advice for abnormal uterine bleeding (AUB) in the United Kingdom. Many low-risk patients who could be managed exclusively in primary care are referred to hospital based gynaecology services. Performing endometrial sampling (ES) in the community may improve care, reduce the rate of referrals and minimise costs. We aimed to search and synthesise the literature on the effectiveness of ES (Pipelle versus other devices) in managing AUB in low-risk patients. METHODS We undertook an electronic literature search in MEDLINE via OvidSP, Scopus, and Web of Science for relevant English-language articles from 1984 to 2016 using a combination of MeSH and keywords. Two reviewers independently pre-selected 317 articles and agreed on 60 articles reporting data from over 7300 patients. Five themes were identified: sample adequacy, test performance, pain and discomfort, cost-effectiveness, and barriers and complications of office ES. RESULTS Pipelle seems to perform as well as dilation and curettage and, as well or better than other ES devices in terms of sampling adequacy and sensitivity. It also seems to be better regarding pain/discomfort and costs. However, Pipelle can disrupt the sonographic appearance of the endometrium and may be limited by cervical stenosis, pelvic organ prolapse and endometrial atrophy. CONCLUSIONS The current evidence supports the use of Pipelle in the management of low-risk women presenting in the outpatient setting with symptomatic AUB when combined with clinical assessment and ultrasound scanning. However, the implications of its widespread use in primary care are uncertain and more research is required.

Abstract
The authors reviewed 2007 consecutive outpatient hysteroscopies performed in self-referred women to assess the detection rate of uterine cancer and the validity of different selection criteria for hysteroscopy. Thirty cases of uterine cancer (29 endometrial, 1 carcinosarcoma) were detected. Abnormal uterine bleeding was the indication most commonly associated with cancer (26 of 30 cases, cancer detection rate = 2.1 %), whereas the presence of cervical polyps had no predictive value. Patients age was correlated to cancer detection rate, and the investigation of uterine cancer under the age of 45 was poorly cost effective. Hysteroscopy and endometrial biopsy, performed by Permacurette or Novak curette immediately after hysteroscopy, missed respectively 8 and 2 of 30 cancers. Hysteroscopy should be employed in combination with endometrial biopsy as a standard outpatient investigation whenever endometrial cancer is suspected. These procedures are safe and accurate and rule out more aggressive and costly procedures, such as dilatation and curettage, in most cases.

Abstract
OBJECTIVE We evaluated the clinical performance of liquid-based endometrial cytology (SurePath™) for detecting endometrial malignancies by comparison with the performance of suction endometrial tissue biopsy. STUDY DESIGN From November 2011 to May 2013, we consecutively collected 1,118 liquid-based endometrial cytology specimens and 674 suction endometrial tissue biopsy specimens. RESULTS The rate of nonpositive final histology in nonpositive liquid-based endometrial cytology (98.2%) was higher than the rate of nonpositive final histology in nonpositive suction endometrial tissue biopsy (97.0%). None of the clinical performance values of liquid-based endometrial cytology for detecting the endometrial malignancies were statistically inferior to those of the suction endometrial tissue biopsy. When the positivity threshold was more than "atypical endometrial cells of undetermined significance," the rate of positive liquid-based endometrial cytology from cases with a positive final histology (84.5%) was higher than the rate of positive suction endometrial tissue biopsy from cases with a positive final histology (69.8%). However, there were still no significant differences among all the performance values. CONCLUSIONS Our liquid-based endometrial cytology would be more appropriate in various clinical situations as the initial detection tool for endometrial malignancies, rather than suction endometrial tissue biopsy. In addition, it could be used in screening for endometrial malignancies on a broader scale.

Abstract
BACKGROUND Endometrial hyperplasia (EH) is a uterine pathology representing a spectrum of morphological endometrial alterations. It is predominantly characterized by an increase in the endometrial gland-to-stroma ratio when compared to normal proliferative endometrium. The clinical significance of EH lies in the associated risk of progression to endometrioid endometrial cancer (EC) and 'atypical' forms of EH are regarded as premalignant lesions. Traditional histopathological classification systems for EH exhibit wide and varying degrees of diagnostic reproducibility and, as a consequence, standardized patient management can be challenging. OBJECTIVE AND RATIONALE EC is the most common gynaecological malignancy in developed countries. The incidence of EC is rising, with alarming increases described in the 40-44-year-old age group. This review appraises the current EH classification systems used to stratify women at risk of malignant progression to EC. In addition, we summarize the evidence base regarding the use of immunohistochemical biomarkers for EH and discuss an emerging role for genomic analysis. SEARCH METHODS PubMed, Medline and the Cochrane Database were searched for original peer-reviewed primary and review articles, from January 2000 to January 2016. The following search terms were used: 'endometrial hyperplasia', 'endometrial intraepithelial neoplasia', 'atypical hyperplasia', 'complex atypical hyperplasia', 'biomarker', 'immunohistochemistry', 'progression', 'genomic', 'classification' and 'stratification'. OUTCOMES Recent changes to EH classification reflect our current understanding of the genesis of endometrioid ECs. The concept of endometrial intraepithelial neoplasia (EIN) as a mutationally activated, monoclonal pre-malignancy represents a fundamental shift from the previously held notion that unopposed oestrogenic stimulation causes ever-increasing hyperplastic proliferation, with accumulating cytological atypia that imperceptibly leads to the development of endometrioid EC. Our review highlights several key biomarker candidates that have been described as both diagnostic tools for EH and markers of progression to EC. We propose that, moving forwards, a 'panel' approach of combinations of the immunohistochemical biomarkers described in this review may be more informative since no single candidate can currently fill the entire role. WIDER IMPLICATIONS EC has historically been considered a predominantly postmenopausal disease. Owing in part to the current unprecedented rates of obesity, we are starting to see signs of a shift towards a rising incidence of EC amongst pre- and peri-menopausal woman. This creates unique challenges both diagnostically and therapeutically. Furthering our understanding of the premalignant stages of EC development will allow us to pursue earlier diagnosis and facilitate appropriate stratification of women at risk of developing EC, permitting timely and appropriate therapeutic interventions.

Abstract
INTRODUCTION Abnormal uterine bleeding (AUB) is the most common symptom of endometrial cancer (EC) and endometrial hyperplasia with (AH) or without (EH) atypia. Risk of malignancy and hyperplasia is significantly lower in premenopausal than in postmenopausal women. Only 10% of EC occurs before menopause. Obesity and age are well-recognized risk factors of endometrial cancer. Endometrial sampling is recommended in women at high risk of endometrial malignancy. The primary objective was to determine the incidence of EC, AH and EH in premenopausal women undergoing dilation and curettage (D&C) because of AUB. Additional objective of the study was to estimate the risk of EC and AH in overweight and obese women with two types of AUB: heavy menstrual bleeding (AUB-HMB) and intermenstrual bleeding (AUB-IMB), according to PALM-COEIN classification. MATERIAL AND METHODS Retrospective study in the population of women undergoing D&C in tertiary hospital because of AUB between Jan-2016 and Dec-2016. The incidence of EC, AH, EH was established. The influence of the variables: age, BMI, AUBHMB/ AUB-IMB on the occurrence of abnormal histology (EC, AH, EH) was evaluated. Finally, the model built by using backward stepwise regression and mechanism of v-fold cross-validation, showed no statistically significant relationship. RESULTS EC was detected in 2/213 cases (0.9%; 95% CI 0.0003 to 0.036), AH in 3/213 cases (1.4%), giving a total of 5/213 (2.3%) women with AH or EC. EH was detected in 16/213 (7.5%) women. High BMI raises the chance of AH diagnosis: OR 1.16 (95% CI 1.05- 1.28). The presence of HMB compared to IMB reduces the chance of EH: OR 0.24 (95% CI 0.07-0.9). IMB increases the chance for the diagnosis of EH 4.11 times compared to HMB (OR 4.1, 95% CI 1.1-14.9; p = 0.016). CONCLUSIONS EC in premenopausal women with AUB undergoing D&C is rare. There is a need to search for more effective methods of selection of patients than commonly used. Age and BMI do not seem to be factors that should be used to select patients.

Abstract
AIMS To evaluate the sampling adequacy and diagnostic accuracy of the endometrial SAP-l sampling device in detecting endometrial lesions based on histopathological examination. MATERIALS AND METHODS In total, 182 patients who required an endometrial biopsy were enrolled in this study. All of the patients underwent endometrial biopsies with the SAP-l sampler prior to hysteroscopy (169/182) or dilatation and curettage (D&C) (13/182). Endometrial tissues were obtained at biopsy for histopathological examination. RESULTS Ad- equate endometrial specimens were obtained in 148 of 182 patients (81.32%). Menopause (p = 0.000), endometrial thickness (p = 0.004), and the types of endometrial diseases (p = 0.009) differed significantly between the two groups. Among the 169 patients who underwent hysteroscopy, sampling scratches were observed in the uterine cavity in 147 cases (86.98%). Compared to traditional methods, such as hysteroscopy and D&C, the sampling diagnostic sensitivity, specificity, and positive and negative predictive values were 82.35%, 100%, 100% , and 97.76% for endometrial carcinoma (n=17) and 37.5%, 100%, 100% and 97.76% for endometrial atypical hyperplasia (n=8), respectively. Those that were misdiagnosed occurred because the lesions were focal or localized in a small part of the uterine cavity. The sampling diagnostic sensitivity for polyps (n=32) was 12.5%. Two patients with submucosal leiomyoma went undiagnosed based on the sample specimens. CONCLUSION Endometrial sampling using the SAP-l sampler is a minimally invasive altemative technique for obtaining adequate endometrial specimens for histopathological examination. The SAP-l sampler was useful in detecting endometrial carcinoma and atypical hyperplasia cases that were not highly suspected to be localized; however, this method was not useful in detecting endometrial polyps and submucosal leiomyomas.

Abstract
BACKGROUND Clinical guidelines recommend that women with abnormal uterine bleeding with risk factors have an endometrial biopsy to exclude hyperplasia or cancer. Given the majority of endometrial cancer occurs in postmenopausal women, it has not been widely recognized that obesity is a significant risk factor for endometrial hyperplasia and cancer in young, symptomatic, premenopausal women. OBJECTIVE We sought to evaluate the effect of body mass index on risk of endometrial hyperplasia or cancer in premenopausal women with abnormal uterine bleeding. STUDY DESIGN This was a retrospective cohort study in a single large urban secondary women's health service. Participants were 916 premenopausal women referred for abnormal uterine bleeding of any cause and had an endometrial biopsy from 2008 through 2014. The primary outcome was complex endometrial hyperplasia (with or without atypia) or endometrial cancer. RESULTS Almost 5% of participants had complex endometrial hyperplasia or cancer. After adjusting for clinical and demographic factors, women with a measured body mass index ≥30 kg/m2 were 4 times more likely to develop complex hyperplasia or cancer (95% confidence interval, 1.36-11.74). Other risk factors were nulliparity (adjusted odds ratio, 3.08; 95% confidence interval, 1.43-6.64) and anemia (adjusted odds ratio, 2.23; 95% confidence interval, 1.14-4.35). Age, diabetes, and menstrual history were not significant. CONCLUSION Obesity is an important risk factor for complex endometrial hyperplasia or cancer in premenopausal women with abnormal uterine bleeding who had an endometrial biopsy in a secondary gynecology service. As over half of women with the outcome in this study were age <45 years, deciding to biopsy primarily based on age, as currently recommended in national guidelines, potentially misses many cases or delays diagnosis. Body mass index should be the first stratification in the decision to perform endometrial biopsy and/or to refer secondary gynecology services.

Abstract
BACKGROUND/AIM Fractal dimension (FD) is widely used in medicine and biology as a tool for defining features of structure. This study aimed to compare pathological endometrium (simple-complex hyperplasia and endometrial carcinoma), as well as the endometrial changes, during the phases of the menstrual cycle. The main goal was the objective measurement of fractal dimension and to refrain from subjective evaluation. MATERIALS AND METHODS Two thousand cases of endometrial tissue from patients who underwent dilatation and curettage (D&C) were reviewed. Out of these, 137 cases were eligible for the study. In each case, immunohistochemistry with cytokeratin Ae1/AE3 was performed in order to simplify the evaluation of the FD. RESULTS Endometria with carcinoma, simple or complex hyperplasia showed significant differences only in the immunohistochemically stained fractal dimensions. As expected, significant differences were also found between atrophic and secretory endometrium and carcinoma. CONCLUSION FD is an objective, rapid and simple procedure for the differential diagnosis between complex hyperplasia and endometrial adenocarcinoma.

Abstract
Postmenopausal bleeding (PMB) accounts for 5% of gynaecology referrals. Investigations should exclude malignancy and pre-malignancy, and diagnose the benign conditions that need treatment. The three modalities that are most commonly used are transvaginal ultrasound scan (TVS), endometrial biopsy (EB) and hysteroscopy. Most authors agree that the first-line investigation should be TVS, followed by endometrial assessment (EB or hysteroscopy) if the endometrial thickness is >4 mm. When scanning demonstrates the possibility of pathology, outpatient hysteroscopy and biopsy are the gold standard for investigating the endometrial cavity. Focal pathology can be removed during the hysteroscopy, thereby reducing hospital admissions and costs.

Abstract
INTRODUCTION Abnormal uterine bleeding is one of the most common morbidity landing women to attend medical attention in gynecology outpatient department. This study aims to evaluate the hysteroscopy finding in diagnosis of AUB and its correlation with ultrasonography finding and histopathological reports. METHODS This was a prospective comparative study in which ultrasonography was performed in fifty patients with abnormal uterine bleeding attending OPD then hysteroscopy was performed.After removing hysteroscopy dilation and curettage was done and sample sent for histopathology.At the end reports of hysteroscopy finding were compared with sonograhic and pathological results. RESULTS In the study women aged from 45 to 64 years with the symptoms duration of 15 days to 6 months. Post menopausal women seek medical attention more early then the menstruating women.Common symptoms are menorrhagia, metrorrhagia and postmenopausal bleeding. Most common abnormality was menorrhagia (32%) followed by post menopausal bleeding 28 %. Ultrasonography showed 46% of abnormal finding in which 17 (47%) menstruating women and 6 (43%) women were postmenopausal women. Among 50 women 17 (34%) had negative finding and 43 (66%) had abnormal finding in which most common finding of hyperplastic endometrium. Hysteroscopy correctly diagnose atrophic endometrium, polyp and endometrial Ca which is also confirmed by histopathology finding. CONCLUSIONS Hysteroscopy is reliable method for evaluating cases of AUB and it can be used as first line diagnostic method for benign lesions. Hysteroscopy guided biopsy has most accurate in diagnosing pathology.

AIM To compare the risk of developing endometrial carcinoma (EC) in young women with atypical endometrial hyperplasia (AEH) undergoing fertility-sparing management compared to women treated by primary hysterectomy. PATIENTS AND METHODS In this multicentric retrospective study, 111 patients with a diagnosis of AEH by endometrial biopsy were included. EC incidence was compared in two groups: 32 patients treated with fertility-sparing management and 79 older patients treated with primary hysterectomy. RESULTS The rates of EC diagnosed by pathology of hysterectomy specimens were comparable between the groups. The probability of developing EC at 12, 24 and 36 months were 14%, 21% and 26%, respectively, in patients managed conservatively, and 29%, 37% and 37%, respectively, in patients treated with primary hysterectomy. CONCLUSION Fertility-sparing management of AEH does not increase the risk of diagnosing EC from the hysterectomy specimen.

Abstract
There are two main types of uterine cancer. Endometrial carcinoma, the most commonly diagnosed genital cancer in women, accounts for most cases (more than 95%) and sarcoma comprises the remainder. Endometrial cancer primarily occurs in postmenopausal women. Risk factors include exposure to high levels of endogenous estrogen (eg, obesity, nulliparity, late menopause) or exogenous estrogen (eg, hormone replacement therapy, tamoxifen) and pelvic radiation. Genetics are involved in a small percentage of cases, notably among women in families with hereditary nonpolyposis colorectal cancer (HNPCC). More than 80% of patients with endometrial cancers present with abnormal uterine bleeding. Endometrial biopsy and transvaginal ultrasound are the first-line tests to evaluate bleeding. If the endometrial lining is thickened on ultrasound, endometrial biopsy is indicated. If symptoms persist after negative biopsy results, or if biopsy results are inadequate, hysteroscopy is performed for tissue sampling. Most patients with endometrial cancer are diagnosed early, when cancer is confined to the uterus. Hysterectomy is the treatment of choice in such cases. Treatment of advanced disease involves radiotherapy and/or chemotherapy. Perimenopausal women should be informed that abnormal bleeding could be a sign of cancer and should be evaluated. However, no routine screening is recommended except for women with HNPCC.

Abstract
Endometrial cancer is the most common gynecological cancer but there is no economically justified screening method. Although we can detect endometrial cells in the sample using PAP test, many studies show low sensitivity and positive predictive value of PAP test for the diagnosis of endometrial cancer. The goal of this research was to determine significance of PAP test for the diagnostics of endometrial carcinoma. Sensitivity and specificity were analyzed with statistical parameters. VCE (vaginal, cervical, endocervical) smears of patients with histologically proven endometrial carcinoma were re-examined in order to determine the proportion of false negative results for endometrial cancer cells in the VCE samples. Study group consisted of all consecutive patients with PAP test performed at the Department of Clinical Cytology of the University Hospital Center Osijek from 2002 until the end of 2014. There was one inclusion criteria: subsequent hysterectomy or curettage within the six month after the PAP test, regardless of histological finding. From a total of 263 patients with previous PAP test and histologically proven endometrial cancer, endometrial cancer was cytologicaly diagnosed in 24.7% (including suspicious and positive findings), while 66.2% patients had normal cytological findings. The diagnostic value of PAP test in detection of endometrial cancer was statistically revealed with 25% sensitivity and 99% specificity. To determine false negative rate VCE samples were reviewed for patients with histologically proven endometrial cancer and negative VCE findings. There were a total of five negative results. In one case revision did not changed the original negative diagnosis, but benign endometrial cells, a lot of blood and inadequate cytohormonal status were found. In three out of four reviewed samples there were missed cells of endometrial adenocarcinoma. Review of remaining VCE sample upgraded the diagnosis from negative to suspicious for endometrial cancer. Proportion of error in the detection of endometrial cancer using cytological findings was 3.4% (true false negatives). Negative rate of the cytological findings in the detection of endometrial cancer was 66.2%. PAP test is not a suitable method for detection of endometrial carcinoma due to low sensitivity (25%). The main cause of negative findings in PAP test was lack of diagnostic cells in the sample.

Abstract
The risk of endometrial hyperplasia (EH) progressing into endometrioid endometrial cancer ranges from 1% for simple EH without atypia (EHWA) to 46.2% for atypical EH (AEH). Differentiation between both entities is crucial to determine optimal management. As preoperative diagnosis of AEH can be difficult, we aimed to establish clusters of immunohistochemical markers to distinguish EHWA from AEH. We studied 13 immunohistochemical markers (steroid receptors, pro/anti-apoptotic proteins, metalloproteinases (MMP), tissue inhibitor of metalloproteinase (TIMP), CD44 isoforms) known for their role in endometrial pathology. Using supervised clustering, we determined clusters of co-expressed proteins which contributed the most in differentiating EHWA from AEH. From 39 tissue samples (17 EHWA and 22 AEH), we found three clusters of co-expressed proteins: Cluster 1 included two proteins (over-expression of estrogen receptor (ER) and under-expression of progesterone receptor (PR) B in AEH compared to EHWA); Cluster 2: an ER, PR A, MMP-2 and TIMP-1 over-expression and a PR B and TIMP-2 under-expression; Cluster 3: over-expression of ER and MMP-7 and under-expression of PR B and TIMP-2. AEH can be accurately distinguished from EHWA using a supervised clustering of immunohistochemical markers. This promising approach could be useful to improve the preoperative diagnosis of EH.

Abstract
The purpose of this study was to evaluate diagnostic efficiency of methods of diffusion-weighted imaging (DWI) in the diagnosis of diseases of the body the uterus at the high and ultra high field MRI (1,5T1, 3,OT1). In total we examined 150 patients. In 72 patients (48%) there were histologically verified malignant changes; of these 70 patients (46.7%) had endome- trial cancer (EC), 2 (1.3%)--uterine sarcoma. 40 EC patients (57.2%) had of Stage I, 15 patients (21.4%)--Stage II, 11 patients (15.7%)--Stage III, and 4 patients (5.8%) of--stage IV. 48 patients (32%) had benign processes of the endometrium (uterine fibroids--27 patients, endometrial hyperplasia--12 patients, endometrial polyps--9 patients). The control group consisted of 30 (20%) healthy patients. All patients underwent MRI examination of the pelvic organs into high and ultra-high MRI (1,5T1, 3,0T1). All patients were required performance of SP DWI (diffusion-weighted images) in 2 projections (Ax and Sag) with different diffusion factors (50-500-1100). MRI data using DWI were compared with surgical material. To our opinion modern MRI techniques allow to reliably determine the size of the pathological process, its location, the extent of the parameters for endometrial cancer, as well as the degree of involvement in the pathological process of the bladder and rectum, to assess the condition of the pelvic lymph nodes. MRI, supplemented DWI, allowed differentiating benign and malignant lesions of the uterus. MRI data corresponded to a post mortem conclusion in the case, specificity 86%, sensitivity of 92% and a diagnostic accuracy of 91%, which significantly improved the diagnostic accuracy of a standard MRI. Thus the method DWI MRI using modern software improves the differential diagnosis of diseases of the body uterus, can reliably assess the extent of the pathological process, to fully assess the invasion of parametrial tissue, provide a comprehensive assessment of the status of the lymph nodes.

Abstract
OBJECTIVE To compare the safety and regression rates of conservative treatments for complex atypical hyperplasia (CAH) between pre- and postmenopausal women. METHODS Historical cohort study of pre- and postmenopausal women with CAH managed conservatively at one center (Royal Women's Hospital, Melbourne, Australia) between September 1999 to June 2012. RESULTS Of the 153 women with CAH, 92 (60%) underwent hysterectomy and the remaining 61 were managed conservatively with oral or intrauterine progestogen: 42 were premenopausal and 19 were postmenopausal. Within 12 months, 32 (76%) premenopausal women demonstrated regression of CAH and none developed endometrial cancer. In contrast, only 4 (21%) postmenopausal women showed disease regression and 4 (21%) progressed to endometrial cancer. Over a median of 24 months, 3 premenopausal women relapsed with CAH and 2 developed endometrial cancer. Four premenopausal women had successful pregnancies. CONCLUSION Conservative treatment with progestogen in premenopausal women with CAH leads to high regression rates within the first 12 months. In contrast, postmenopausal women have high rates of ongoing disease and cancer progression and conservative therapy should be avoided.

Abstract
BACKGROUND Obesity has been linked to abnormal estrogen regulation, endometrial hyperplasia, and endometrial cancer (EC). Our group has shown that hormone receptor expression profiles in the endometria of morbidly obese women change with weight loss, in some cases concordantly with resolving hyperplasia; however other potential drivers of neoplasia, including altered immunologic tolerance exist. The objective of this study was to evaluate the effect of bariatric surgery induced weight loss on the expression patterns of nonhormone receptor biomarkers associated with cancer and immunity. METHODS Endometrial biopsies were obtained from 59 asymptomatic, morbidly obese women at the time of bariatric surgery and again 1 year postsurgery. Tissue microarrays were created and immunohistochemical stains for CD3, CD20, and PTEN were performed on all samples and evaluated by 2 blinded pathologists independently. Approximately 50% of participants had sufficient tissue for analysis at both visits. McNemar/Bowker tests of symmetry were performed to compare proportions between categories for matched pairs (pre- and post-treatment). RESULTS Endometrial hyperplasia was identified in 4 women despite negative clinical histories and resolution of hyperplasia after weight loss occurred in 3 women. While overall no significant differences were observed between matched pre and postsurgery levels of CD20 and CD3 positive cells, a tendency toward decreased expression levels from baseline status was observed for CD20. No differences were observed for PTEN. CONCLUSION Our data demonstrate that the prevalence of endometrial pathology appears to be partially mitigated by weight loss. Weight loss is associated with alterations in the hormone receptor profiles, but these data suggest that changes in the immune response, as measure be expression of CD20+, may be relevant targets for EC prevention research.
