Comparing endometrial biopsy results with hysteroscopic pathology in women presenting with abnormal and postmenopausal uterine bleeding. J Gynecol Obstet Hum Reprod 2023; 52:102685. [PMID: 37871649 DOI: 10.1016/j.jogoh.2023.102685] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 08/30/2023] [Accepted: 10/20/2023] [Indexed: 10/25/2023]
Abstract
OBJECTIVE To compare pathology results after office-based blind endometrial biopsy and pathology results from hysteroscopy in women presenting with abnormal uterine bleeding (AUB). METHODS A retrospective cohort study of biologic women presenting with AUB at a tertiary care referral care center. Patients were included if they underwent evaluation with blind endometrial biopsy performed in the office followed by hysteroscopy within one year. Hysteroscopic findings and pathology were correlated with index endometrial biopsy findings. RESULTS 689 patients met inclusion criteria. The mean age and BMI were 49 (±10) years and 31 (±8) kg/m2. The median duration of bleeding leading up to presentation was of 3.5 (1.5-9) months. Of the patients who had operative hysteroscopic pathology demonstrating endometrial polyp, 30.6 % (81) had a polyp detected on office endometrial biopsy. Of the patients who had hysteroscopic pathology demonstrating intracavitary fibroids, 0 % (0) were detected on endometrial biopsy. Of the patients who had hyperplasia without atypia on hysteroscopy, 28.6 % (4) were detected or suspected on endometrial biopsy. Of the patients who had hyperplasia with atypia on hysteroscopy, 5.9 % (1) were detected or suspected on endometrial biopsy. There were 12 cases of confirmed or suspected malignancy on hysteroscopy, of which 8.3 % (1) were detected on endometrial biopsy. CONCLUSION Concordance between focal findings on office hysteroscopy and endometrial biopsy is low. Endometrial biopsy when malignancy is suspected has been shown to be of benefit, but in the setting of suspected benign focal pathology, blind assessment of the endometrial cavity for definitive diagnosis should be abandoned. In women with symptomatic uterine bleeding, hysteroscopic visualization is associated with increased sensitivity in identifying intrauterine pathology.

Clinical study of classification and regression tree assisted endometrial biopsy in the diagnosis of endometrial carcinoma. Am J Cancer Res 2023; 13:5394-5404. [PMID: 38058822 PMCID: PMC10695821] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Accepted: 10/25/2023] [Indexed: 12/08/2023] Open
Abstract
The early diagnosis of endometrial carcinoma is critical for improving patient survival and prognosis. However, the diagnostic efficiency of a single examination is often insufficient, because it is easy to cause misdiagnosis and missed diagnoses. Therefore, this study used the classification and regression tree (CART) algorithm to establish and validate a CART model to distinguish endometrial carcinoma from other endometrial lesions. The clinical data of 297 patients treated at Changde Hospital, Xiangya School of Medicine, Central South University between April 2021 and April 2023 for postmenopausal uterine effusion, postmenopausal vaginal bleeding, abnormal uterine bleeding and endometrial thickening were retrospectively analyzed. Among them, there were 203 cases of endometrial carcinoma and 94 cases of endometrial lesions. The pathological results from endometrial biopsy and hysteroscopic curettage were compared. The coincidence rate of endometrial biopsy was 90.34% (187/207) and the AUC, sensitivity, and specificity of the diagnosis of endometrial carcinoma were 0.920, 0.914, and 0.925, respectively. Six serological indicators with diagnostic significance were screened out: carbohydrate antigen 125 (CA125), carbohydrate antigen 19-9 (CA19-9), human epididymis secretory protein 4 (HE4), vascular endothelial growth factor (VEGF), D-dimer, and absolute neutrophil count (N). The AUC, sensitivity and specificity of the CART model based on the above indicators were 0.949, 0.979, and 0.896, respectively. The CART model is an intuitive and simple tool for the clinical diagnosis of endometrial carcinoma and endometrial lesions.

Hysteroscopic biopsy compared with endometrial curettage to assess the preoperative rate of atypical hyperplasia underestimating endometrial carcinoma. Arch Gynecol Obstet 2023; 308:971-979. [PMID: 37160470 DOI: 10.1007/s00404-023-07060-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Accepted: 04/25/2023] [Indexed: 05/11/2023]
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.

Identifying women 45 years and younger at elevated risk for endometrial hyperplasia or cancer. Gynecol Oncol 2023; 174:98-105. [PMID: 37172411 DOI: 10.1016/j.ygyno.2023.04.019] [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: 01/18/2023] [Revised: 04/18/2023] [Accepted: 04/19/2023] [Indexed: 05/15/2023]
Abstract
OBJECTIVE To estimate the prevalence of, and identify risk factors associated with, endometrial hyperplasia and/or cancer (EH/EC) in patients ≤45 years old undergoing endometrial sampling for abnormal uterine bleeding (AUB). METHODS We performed a retrospective cohort study of patients 18-45 years old with AUB who underwent endometrial sampling between 2016 and 2019 within a US-based multi-hospital system using billing code queries. We used multivariable Poisson regression to identify factors associated with EH/EC and calculated prevalence stratified by these factors. We estimated predicted probabilities within combinations of characteristics in order to examine the range of risk in this population. RESULTS Among 3175 patients, median age was 39 years (interquartile range [IQR]:35-43) and BMI was 29.7 kg/m2 (IQR: 24.2-36.9). Thirty-nine percent were non-Hispanic White, 41% non-Hispanic Black, 9% Hispanic, and 11% Asian/Other/Unknown. BMI and polycystic ovarian syndrome (PCOS) were associated with higher EH/EC risk; non-Hispanic Black race was associated with lower risk. EH/EC prevalence ranged from 2% in BMI <25 to 16% in BMI ≥50 kg/m2 (p-trend <0.001). These prevalence estimates differed by race/ethnicity with the lowest estimates in non-Hispanic Black patients (0.5% BMI <25 vs. 9% BMI ≥50) and highest in Hispanic patients (1.5% BMI <25 vs. 33% BMI ≥50). Accounting for combinations of risk factors, predicted probabilities were highest - 34-36% - among patients with PCOS, diabetes, BMI ≥50, and Hispanic or Asian/Other/Unknown race/ethnicity. CONCLUSIONS When accounting for combinations of key risk factors, risk of EH/EC in patients ≤45 years old with AUB ranges widely; the more nuanced estimates of risk presented here could help inform clinical decision-making about endometrial sampling in this population.

Endometrial Biopsy: Indications, Techniques and Recommendations. An Evidence-Based Guideline for Clinical Practice. J Gynecol Obstet Hum Reprod 2023; 52:102588. [PMID: 37061093 DOI: 10.1016/j.jogoh.2023.102588] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Revised: 12/04/2022] [Accepted: 04/05/2023] [Indexed: 04/17/2023]
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.

Endogenous progesterone in unexplained infertility: a systematic review and meta-analysis. J Assist Reprod Genet 2023; 40:509-524. [PMID: 36572790 PMCID: PMC10033797 DOI: 10.1007/s10815-022-02689-5] [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: 04/21/2022] [Accepted: 12/08/2022] [Indexed: 12/28/2022] Open
Abstract
PURPOSE To investigate the possibility that altered actions of endogenous progesterone affect receptivity and contribute to unexplained infertility (UI). METHODS Two authors electronically searched MEDLINE, CINAHL and Embase databases from inception to 6 July 2022 and hand-searched according to Cochrane methodology. We included all published primary research reporting outcomes related to endogenous progesterone in natural cycles in women with UI. Studies were assessed for risk of bias using a modified Newcastle-Ottawa Score or NHLBI Score. We pooled results where appropriate using a random-effects model. Findings were reported as odds ratios or mean differences. RESULTS We included 41 studies (n = 4023). No difference was found between the mid-luteal serum progesterone levels of women with UI compared to fertile controls (MD 0.74, - 0.31-1.79, I2 36%). Women with UI had significantly higher rates of 'out-of-phase' endometrium than controls. Nine out of 10 progesterone-mediated markers of endometrial receptivity were significantly reduced in women with UI compared to fertile controls (the remaining 1 had conflicting results). Resistance in pelvic vessels was increased and perfusion of the endometrium and sub-endometrium reduced in UI compared to fertile controls in all included studies. Progesterone receptor expression and progesterone uptake were also reduced in women with unexplained infertility. CONCLUSIONS End-organ measures of endogenous progesterone activity are reduced in women with UI compared to fertile controls. This apparently receptor-mediated reduction in response affects endometrial receptivity and is implicated as the cause of the infertility. Further research is required to confirm whether intervention could overcome this issue, offering a new option for treating unexplained infertility.

Abstract
OBJECTIVES To establish and verify a hysteroscopic scoring system for the diagnosis of chronic endometritis (CE) in infertile patients. METHODS A total of 238 infertile patients who underwent hysteroscopy and endometrial biopsy in the Reproductive Medicine Center, Shijiazhuang Obstetrics and Gynecology Hospital Affiliated to Hebei Medical University from October 1 to December 31, 2019 were enrolled in the study. According to the results of CD138 immunohistochemistry, the patients were divided into CE group (n=73) and non-CE group (n=165). Univariate and binary logistic regression analyses were used to screen the risk factors of CE and a nomogram was establish for hysteroscopic scoring. Receiver operating characteristic (ROC) curve, calibration curve and Bootstrap resampling method were used to evaluate and verify the system. RESULTS Univariate and binary logistic regression analyses showed that hyperemia area (HA) degree ≥2, micropolyps, polypoid hyperplasia of endometrium and history of ectopic pregnancy were independent risk factors for CE (all P<0.05). A nomogram was generated to establish a hysteroscopy scoring system based on the above four factors. The area under ROC curve of the hysteroscopy scoring system for predicting CE was 0.801 (95%CI:0.742-0.861), the sensitivity was 74.0% and the specificity was 73.9%. The calibration curve showed that the predicting value of the scoring system was highly consistent with the actual value. In the internal verification, the C-index was 0.7811. The predicting value of the verification group in the calibration curve was basically consistent with the actual value, indicating that the scoring system had good stability. CONCLUSIONS The hysteroscopic scoring system composed of HA, micropolyp, polypoid hyperplasia of endometrium and history of ectopic pregnancy can effectively and intuitively predict CE, which is conducive to improving the diagnosis of CE.

The effects of Saline Infusion Sonography on the histological quality of endometrial sampling in women with postmenopausal bleeding. BMC Womens Health 2023; 23:46. [PMID: 36739405 PMCID: PMC9899370 DOI: 10.1186/s12905-023-02178-6] [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: 08/01/2022] [Accepted: 01/13/2023] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The aim of this study is to analyze the histopathological features of endometrial samples obtained by aspiration when performed before or after the saline contrast sonohysterography in women with postmenopausal bleeding and a thickened endometrium. Hypothetically, the saline infusion could disrupt the tissue and therefore affect the quality of the sample. Furthermore, we want to determine which histological features have impact on the quality of the endometrial sample. METHODS We performed a randomized controlled trial (ESPRESSO trial) in which we analyzed the aspiration samples in two groups. Women were allocated either to saline contrast sonohysterography and subsequent endometrial sampling (SCSH-Sampling group) or to the opposite order (Sampling-SCSH group). Dedicated gyneco-pathologists retrospectively assessed the specimens and recorded the type (blood, mucus, epithelium, intact glands, stroma and tissue context) and quantity (on a scale of 0-3) of material that was found in the specimens. RESULTS This analysis consisted of 197 samples, with 101 women in the SCSH-Sampling group and 96 women in the Sampling-SCSH group. No significant differences were found in the histological features between the two groups. All significant histological features differed significantly in the sufficient samples compared to the insufficient samples: higher amounts of blood, more endometrial epithelium, presence of intact endometrial glands, better stroma and tissue context. Oppositely, a significantly higher amount of mucus was found in the insufficient samples. CONCLUSION This study shows that the histological features of the endometrial sample were not affected by the saline contrast sonohysterography, when performed prior to the tissue sampling.

Abstract
RESEARCH QUESTION What is the effect of chronic endometritis on patients with infertility, the necessity of endometrial re-examination and the effect of improving chronic endometritis after one cycle of antibiotic treatment on pregnancy outcomes? DESIGN Infertile patients (n = 4003) who underwent IVF and intracytoplasmic sperm injection treatment were included. Pregnancy outcomes of groups positive for chronic endometritis were compared with groups that were negative (group 1). Patients that were positive were divided into the chronic endometritis new biopsy group (group 2) and chronic endometritis non-re-examination group (group 3). After doxycycline treatment and re-examination, the chronic endometritis new biopsy group was divided into improved chronic endometritis group (ICE) and not-improved chronic endometritis group (NICE), and their general indicators and reproductive outcomes were compared. RESULTS No significant difference was observed in embryo implantation, early or late pregnancy loss, ectopic pregnancy, clinical pregnancy and live birth rates between groups 2 and 3. The clinical pregnancy and live birth rates in the NICE group were significantly lower than those in the ICE group (P = 0.008 and P = 0.001, respectively). After controlling for potential confounding factors, age, average number of high-quality embryos, endometrial thickness on the day of embryo transfer and number and type of embryo transfer were factors associated with live birth rates. CONCLUSIONS Endometrial re-examination of women with chronic endometritis treated with doxycycline had no effect on pregnancy outcomes. The first cycle of doxycycline treatment could effectively improve reproductive outcomes of women with five or more CD138+ cells/high-power field.

Abstract
PURPOSE The main goal of this study is to assess the diagnostic agreement between preoperative biopsy and definitive histology of the surgical specimen to determine which sampling method is most suitable for diagnosis of early-stage endometrial cancer. METHODS We performed a retrospective multicentric study to assess the correlation between three endometrial sampling methods (hysteroscopy, pipelle and D&C) in patients who had undergone preoperative endometrial biopsy and received primary surgical treatment for endometrial cancer. The primary objective was the agreement rate between hysteroscopy (HSC), endometrial biopsy (pipelle) and dilatation and curettage (D&C). RESULTS A total of 1833 women who underwent preoperative sampling at 15 centers were included: 1042 biopsies were performed by HSC, 703 by pipelle and 88 by D&C. All three methods presented a moderate diagnostic concordance (κ = 0.40-0.61) with the definitive specimen's histology: HSC (κ = 0.47), pipelle sampling (κ = 0.48) and D&C (κ = 0.48). Likewise, a subgroup analysis was performed by histological subtype comparing HSC and endometrial biopsy, showing that neither is superior as a diagnostic method. CONCLUSIONS According to this study, the use of pipelle sampling could become an adequate diagnostic method in endometrial cancer due to its similar agreement to HSC, ease of use and affordability.

Abstract
Background: Inflammation and its master regulator, Nuclear Factor-kB (NF-kB), have been implicated in the development of endometriosis. Inhibition of NF-kB pathway using small molecules ameliorated disease progression and reduced the lesion size; nevertheless, the underlying mechanism is not fully understood. Therefore, this study, is an attempt to assess whether inhibiting NF-kB signaling by aloe-emodin (AE) or aspirin (Asp), as anti-inflammatory compounds, can suppresses the invasive activity of human endometrial stromal cells at stage IV endometriosis. Methods: The eutopic and healthy endometrial biopsies from a total of 8 infertile women with confirmed endometriosis and 8 women without endometriosis were digested and the single cells were cultured. Gene and protein markers of proliferation, migration, adhesion, and invasion of eutopic endometrial stromal cells (EuESCs) with and without treatment with AE or Asp, as well as control endometrial stromal cells (CESCs) was analyzed using q-PCR and immunofluorescence staining, respectively. Comparison between groups was performed using one-way ANOVA and the Bonferroni post hoc and p≤0.5 was considered statistically significant. Results: There was an association between NF-kB overexpression and higher proliferation/adhesion capacity in EuESCs. EuESCs (at stage IV endometriosis) displayed no invasive and migratory behaviors. Pre-treatment of EuESCs with AE or Asp significantly attenuated NF-kB expression and reduced proliferative, adhesive, invasive, and migratory activity of endometrial cells (p≤0.5). Conclusion: Eutopic endometrial stromal cells seem to have a semi-invasive activity which is largely suppressed by AE or Asp. It can be suggested that both Asp and AE (as potent NF-kB inhibitors) can be used as a supplement in conventional endometriosis treatments.

Abstract
Abnormal uterine bleeding is a frequent medical concern for premenopausal and postmenopausal patients. Endometrial biopsy is a safe, cost-effective option offered in the office setting. Although endometrial biopsy may result in insufficient tissue or false-negative results, data suggest that endometrial biopsy is 90% sensitive for endometrial cancer and 82% sensitive for atypical hyperplasia, with specificity of 100% for postmenopausal patients and similar results in premenopausal patients. Topical cervical analgesia and oral nonsteroidal anti-inflammatory drugs decrease a patient's discomfort during endometrial biopsy. Aftercare instructions and how patients want to receive results should be reviewed in advance of performing the endometrial biopsy.

Abstract
OBJECTIVE To explore the views of members of the British Menopause Society on the management of women with unscheduled bleeding on hormone replacement therapy. STUDY DESIGN An electronic cross-sectional questionnaire survey. MAIN OUTCOME MEASURES Investigations, treatment options and preferences for the management of women with unscheduled bleeding on hormone replacement therapy. RESULTS A total of 91/178 (51%) clinicians investigate patients with unscheduled bleeding within three to six months of starting sequential hormone replacement therapy (seq-HRT) versus 83/178 (47%) for continuous combined hormone replacement therapy (con-HRT). A total of 52/178 (29%) versus 54/178 (30%) would investigate unscheduled bleeding continuing beyond six months while 18/178 (10%) versus 26/178 (15%) would investigate within three months. Assessment is requested as urgent by 88/176 (50%) clinicians, routine by 47/176 (27%) and a two-week-wait-suspected cancer referral by 41/176 (23%). A total of 97/178 (55%) clinicians would continue seq-HRT and refer versus 117/178 (66%) for con-HRT. A total of 46/178 (26%) clinicians would change the progestogen preparation in women with unscheduled bleeding on seq-HRT. For women on con-HRT, 12/178 (7%) clinicians would change to seq-HRT and 8/178 (5%) to the Mirena IUS. The Mirena IUS is the preferred progestogen for 81/178 (45%) of clinicians when prescribing hormone replacement therapy. CONCLUSIONS There is a varied approach in the practise amongst British Menopause Society members to managing women with unscheduled bleeding on hormone replacement therapy. Further research is needed to determine the optimal assessment pathways for women with unscheduled bleeding on hormone replacement therapy.

Abstract
OBJECTIVE Emerging technologies may enable detection of endometrial cancer with methods that are less invasive than standard biopsy methods. This study compares patient pain scores among 3 office gynecologic tract sampling methods and explores their potential determinants. METHODS A prospective study including 3 sampling methods (tampon, Tao brush (TB), endometrial biopsy (EB)) was conducted between December 2015 and August 2017 and included women ≥45 years of age presenting with abnormal uterine bleeding, postmenopausal bleeding, or thickened endometrial stripe. Patients rated pain after each sampling procedure using a 100-point visual analog scale (VAS). RESULTS Of 428 enrolled, 190 (44.39%) patients underwent all 3 sampling methods and reported a VAS score for each. Nearly half were postmenopausal (n = 93, 48.9%); the majority were parous (172, 90.5%) of which 87.8% had at least one vaginal delivery. Among the 190 patients, the median (IQR) pain score was significantly lower for sampling via tampon (0 [0,2]) compared to TB (28 [12, 52]) or EB (32 [15, 60]) (both p < 0.001, Wilcoxon signed rank test). Among women who underwent tampon sampling, age and pain scores showed a weak positive correlation (Spearman rank correlation, r = 0.14; p = 0.006); EB sampling was associated with a weak inverse correlation between parity and pain scores (r = -0.14; p = 0.016). CONCLUSION Gynecologic tract sampling using a tampon had significantly lower pain than both EB and TB. Pain with tampon sampling was positively correlated with age and pain with EB sampling was inversely correlated with parity. Pain scores for TB and EB were not significantly related to age, menopausal status, or BMI.

[PMID: 33571678 DOI: 10.1016/j.jmig.2021.02.004] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Revised: 02/02/2021] [Accepted: 02/04/2021] [Indexed: 10/22/2022]
Abstract
STUDY OBJECTIVE Operative hysteroscopy requires elevated intrauterine pressures, which could lead to the spread of malignant cells into the peritoneal cavity. Currently, there is a paucity of data analyzing clinical outcomes in endometrial cancer after hysteroscopic morcellation with newer equipment. In this study, we sought to determine whether there are increased rates of positive peritoneal cytology, lymphovascular space invasion, or surgical upstaging in patients undergoing hysteroscopic morcellation compared with alternative endometrial biopsy methods. DESIGN A retrospective chart review of patients from 2013-2018 was performed. The exclusion criteria included biopsy at outside institution, stage IV endometrial cancer known before biopsy, and missing data regarding biopsy method and histology. Peritoneal cytology results, lymphovascular space invasion, and surgical staging were compared by method of biopsy and histology using chi-square and Kruskal-Wallis tests. SETTING The patients included in this study were accrued from the Karmanos Cancer Insittute in Detroit, Michigan. PATIENTS A total of 289 patients met the inclusion criteria: 184 patients were classified as low-grade (Fédération Internationale de Gynécologie et d'Obstétrique grades 1 and 2) and 105 as high-grade (Fédération Internationale de Gynécologie et d'Obstétrique grade 3, serous, clear cell, and carcinosarcoma) endometrial cancer. INTERVENTIONS Fifty-three patients (18%) underwent hysteroscopy with morcellation. Alternative biopsy methods included hysteroscopy without morcellation, n = 81 (28%); endometrial biopsy, n = 112 (38.7%); and dilation and curettage, n = 43 (15%). MEASUREMENTS AND MAIN RESULTS Positive peritoneal cytology was noted in 34 cases (12%) and negative cytology in 165 (57%). Cytology was not performed in 90 cases (31%). When comparing outcomes by histologic subtypes, no difference was seen in peritoneal cytology (p = .704 and .727 for low grade and high grade, respectively), stage (p = .773 and .053 for low grade and high grade, respectively) or lymphovascular space invasion (p = .400 and .142 for low grade and high grade, respectively). CONCLUSION Our study demonstrates that hysteroscopy with morcellation is a safe diagnostic method for low- and high-grade endometrial pathologic conditions and does not lead to increased dissemination of malignant cells, lymphovascular space invasion, or upstaging of patients.

Impact of endometrial sampling technique and biopsy volume on the diagnostic accuracy of endometrial cancer. Transl Cancer Res 2020; 9:7697-7705. [PMID: 35117372 PMCID: PMC8799147 DOI: 10.21037/tcr-20-2074] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Accepted: 07/06/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND Histotype and tumor grading of endometrial cancer are the most important factors that have to be assessed by preoperative endometrial sampling, and their concordance with the final surgical and definitive histological findings is of paramount importance. We aim to compare histotype and tumor grading concordance of various endometrial sampling techniques (ESTs) and to investigate the role of endometrial volume biopsy. METHODS We performed a retrospective analysis of patients with apparent early stage endometrial cancer collecting demographic, clinical data, type of EST, pathological characteristics of endometrial biopsies and final specimens. We classified ESTs as dilation and curettage (D&C), diagnostic hysteroscopy with D&C, outpatient hysteroscopy and operative hysteroscopy with or without D&C. Diagnostic and operative hysteroscopy were performed with Bettocchi's 5 mm hysteroscope. We evaluated concordance for histotype, and tumor grading, and we performed subgroup analysis based on the technique and final tumor grading. Concordance was classified from good, moderate, sufficient, fair, poor and none using Cohen k-statistic. Finally, we investigated the existence of independent risk factors for discordant tumor grading using multivariate binary logistic regression. RESULTS We collected 148 patients and of these 131 (88.5%) were diagnosed with endometrioid histotype and 65 (44%), 46 (31%) and 37 (25%) respectively with well, moderate and poor differentiated tumors. Atypical hyperplasia (AH) was detected preoperatively in 28 patients (19%). Histotype concordance was fair (k=0.35) and tumor grading concordance was moderate (k=0.45); particularly, concordance was fair in well-differentiated cases (k=0.38); concordance was moderate in moderate- and poor-differentiated cases (k=0.52) and good (k=0.71). Operative hysteroscopy showed moderate concordance for histotype (k=0.41), while grading concordance was fair for G1 (k=0.41), moderate for G2 (k=0.58) and good for G3 (k=0.72), regardless the use of D&C. Preoperative volume biopsy did not impact the concordance of tumor grading, while the adoption of operative hysteroscopy (with or without D&C) decreased the risk of grading discordance in G3 tumors (HR 0.17; 95% CI: 0.03-0.94; P=0.04). Conversely, time elapsed from diagnosis to treatment in well-differentiated tumors increased the risk of discordant results (HR 1.06; 95% CI: 1.02-1.52; P=0.04). CONCLUSIONS Operative hysteroscopy demonstrated the best tumor grading concordance, especially in poor-differentiated tumors. The volume of biopsy did not affect the tumor grading concordance.

Accuracy of preoperative endometrial biopsy and intraoperative frozen section in predicting the final pathological diagnosis of endometrial cancer. Surg Oncol 2020; 35:229-235. [PMID: 32932219 DOI: 10.1016/j.suronc.2020.09.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2020] [Revised: 06/19/2020] [Accepted: 09/06/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Histotype and grade of endometrial cancer (EC) are prognostic factors of nodal involvement and thus of survival. Preoperative biopsy (PB) and intraoperative frozen section (FS) are usually used to guide surgical staging on which the choice of adjuvant therapy will be based successively. OBJECTIVE The aim of this study was to assess the agreement rate between PB and FS with final diagnosis (FD) in a series of surgically resected EC. MATERIALS All patients submitted to hysterectomy for EC or atypical endometrial hyperplasia in the Reggio Emilia Province hospitals from 2007 to 2018 were included. Concordance rate differences in histotype, grading, myoinvasion, risk of recurrence between PB, FS and FD were assessed with Fisher's exact test and Mc Nemar contingency test. RESULTS A total of 352 patients were identified. For 345 patients it was possible to compare PB and FD results. FS examination was performed in 201/352 (57%) cases, while for 21/352 (6%) patients only an intraoperative macroscopic evaluation was done; in the remaining women, FS-exam was omitted. In 14/201 (7%) cases the tumor wasn't grossly identifiable and the random FS-sampling wasn't able to find the tumor site. High diagnostic concordance of tumor type between PB and FD was observed: no significant differences were registered in type 1 and type 2-endometrial cancer identification (83%, 73%, p = 0.121). Significant differences (p = 0.005) were observed comparing FS and FD results: 95% of type 1-ECs were correctly diagnosed by FS, while only 76% of type 2-ECs received a correct diagnosis on FS. PB showed a concordance with FD among tumor grading close to 55% whilst concordance achieved 71% grouping low grade (G1-G2) EC. No significant differences in FS and FD concordance rate were observed between tumor grades. Concordance for low grade was significantly higher than for high grade ECs (89% vs 50%, respectively, p value = 0.014). The concordance rate in evaluating the myoinvasion status between FS and FD was 80% (n: 199 patients), reaching 99% after combining the first 2 groups (0-49% vs ≥ 50%). Twenty-two cases underwent only intraoperative macroscopic evaluation of the myoinvasion, with an accuracy of 91%: only in 1 case the invasion of the cervical stroma was not detected (Stage II), and 1 case the patient was overstaged as Ib. Discrepancies were observed in FS capacity to correctly predict the final ESMO risk group in stage I patients: FS resulted particularly reliable in predicting a low-risk (concordance with FD: 91%) while the accuracy sharply decreased for intermediate- and high-risk patients (62% and 40%, respectively). To investigate the usefulness of FS in EC management, we compared patients who underwent FS (FS-group) or not (no-FS-group). Especially for low risk patients, the FS significantly increased the adequacy of surgical treatment from 53% (no-FS-group) to 72% (FS-group) (p = 0.016). CONCLUSIONS FS remains a useful tool to tailor surgery in EC-patients, avoiding secondary surgery to complete staging particularly in patients with AH + AHBA, low and intermediate risk ECs that could benefit from adjuvant therapy.

Evaluating the diagnostic performance of preoperative endometrial biopsies in patients diagnosed with high grade endometrial cancer: A study of the Society of Gynecologic Oncology (GOC) Community of Practice (CoP). Gynecol Oncol 2020; 159:52-57. [PMID: 32694064 DOI: 10.1016/j.ygyno.2020.06.510] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Accepted: 06/30/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND High grade cancers account for a disproportionate number of recurrences in patients with endometrial cancer. Accurately identifying these cases on endometrial biopsies allows for better surgical planning. This study evaluates the diagnostic accuracy of general pathologists (GP) compared to gynecological pathologists (GYNP) in interpreting preoperative biopsies. METHODS A retrospective cohort study was conducted of patients diagnosed with high grade endometrial cancer (HGEC) between 2012 and 2016 at eight Canadian cancer centres. Data was collected from medical records. Pre-operative biopsies were categorized into groups; biopsies read by GP, GYNP and GP reviewed by GYNP. Rates of HGEC on pre-operative biopsy were calculated. Fisher exact test was used to compare differences between the groups. Univariate logistic regression analysis was conducted for HGEC prediction. RESULTS Of 1237 patients diagnosed with HGEC, 245 (19.8%) did not have a preoperative diagnosis of high-grade disease. Discordancy was identified in 91/287 (31.71%) of biopsies reported by GP, and in 114/910 (12.53%) of biopsies reported by a GYNP (p < 0.0001). Compared to GP, GYNP were 3.24 (CI 2.36-4.45) times more likely to identify high grade disease on preoperative biopsy. Patients whose biopsy was reported by a GYNP were more likely to have a comprehensive staging procedure (OR 1.77 CI 1.33-2.38) and less likely to receive adjuvant therapy (OR 0.71 CI 0.52-0.96). CONCLUSION GYNP are more likely to identify HGEC on pre-operative biopsies. Due to high rates of overall discordancy, it is possible that surgical staging procedures should not be based solely on preoperative biopsy. Further strategies to improve pre-operative biopsies' accuracy are needed.

Effects of Hysteroscopic and Uterine Body Insemination on the Presence of Selected Immune Cells in the Equine Endometrium. J Equine Vet Sci 2020; 90:103023. [PMID: 32534786 DOI: 10.1016/j.jevs.2020.103023] [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: 01/22/2020] [Revised: 03/13/2020] [Accepted: 04/08/2020] [Indexed: 10/24/2022]
Abstract
The effects of standard uterine body and hysteroscopic insemination on endometrial health were investigated. For this purpose, 33 mares were assigned to five different protocols: control (no insemination; n = 7), sham AI (sham uterine body insemination; n = 6), sham HysAI (sham hysteroscopic insemination; n = 7), standard AI (standard uterine body insemination, 300 × 106 progressively motile sperms (PMS); n = 7) and HysAI (hysteroscopic insemination, 100 × 106 PMS; n = 6). Sampling included uterine swabbing for microbiological examination, cytology for determination of polymorphonuclear neutrophils (PMNs) in the uterus, and endometrial biopsy collection for histology and characterization of endometrial immune cells on day 18 after ovulation (B1) as well as 8-10 hours (B2, day 20) and 72 hours after insemination (B3, day 23). Microbial contamination increased throughout the experiment in the sham insemination groups. Significant effects (P < .05) over time were detected for PMNs (cytology: sham HysAI, standard AI, and HysAI; histology: standard AI and HysAI), macrophages (immunohistochemistry: standard AI and HysAI) and T cells (immunohistochemistry: standard AI), showing an increase at B2 and a subsequent decrease toward baseline levels at B3. At B2, significant differences (P < .05) existed for PMNs (mean ± SEM) between control (1.3 ± 1.9%) and sham AI (2.2 ± 2.7%) versus standard AI (12.2 ± 4.7%) and for macrophages between control (4.1 ± 3.5%) and sham AI (2.5 ± 1.3%) versus standard AI (25.4 ± 15.8%). Thus, the cellular immune response of the endometrium depends on sperm deposition in the uterus and does not differ between hysteroscopic and standard uterine body insemination.

Abstract
Epidermal growth factor (EGF) concentrations in the uterus show two peaks on days 2–4 and 13–14 during the estrous cycle in fertile cows. Loss of the two peaks has been linked to reduced
fertility in repeat breeder cows. This study aimed to examine the effect of seminal plasma (SP) on normalizing endometrial EGF concentrations and restoring fertility in repeat breeder cows
with low EGF concentrations on day 3. In study 1, we examined the effect of the deposition sites (the vagina and uterus) of SP on the endometrial EGF concentrations in repeat breeder cows.
SP infusion into the vagina, but not uterus, on the first day of the estrus cycle (day 0) normalized the endometrial EGF concentrations (≥ 4.7 ng/g tissue weight) on day 3. In study 2, the
effect of SP volume (0.5 and 10 ml of SP and 0.5 ml of SP diluted to 10 ml) on EGF concentrations was examined. All groups with SP infusion had increased EGF concentrations on day 3, and
cows with 10 ml of SP and 0.5 ml of SP diluted to 10 ml showed the highest levels of EGF concentrations. In study 3, we examined the effect of SP infusion on fertility. SP infusion
normalized two peaks of endometrial EGF concentrations in about 60% of repeat breeder cows and produced more pregnancies than the controls (44.4 vs. 19.4%). Therefore, we
concluded that SP may contain an activity to normalize the EGF profile and restore fertility in repeat breeder cows with altered EGF profiles.

Abstract
INTRODUCTION The presence of atypical endometrial cells in the Papanicolaou (Pap) test has been associated with an increased rate of endometrial malignancy, with reported rates ranging from 14% to 47%. However, most reported studies have focused on patients who were aged >40 years. The purpose of the present study was to investigate the clinical significance of identifying atypical endometrial cells in Pap test samples in women aged <40 years of age. MATERIALS AND METHODS A search of the cytology Pap test database was performed from 2000 to 2014 using the keywords "atypical endometrial cells" or "atypical glandular cells favor endometrial origin" in women aged <40 years. The available ThinPrep slides were reviewed. The patients' clinical presentation, follow-up endometrial biopsy findings, treatment, and clinical follow-up data were recorded. Endometrial carcinoma tissue sections were screened for Lynch syndrome. RESULTS The database search yielded 63 study cases. Of these 63 patients, 52 had subsequently undergone endometrial biopsy. Of the 52 patients with follow-up biopsy findings available, 9 (17.3%) had premalignant (5 with atypical hyperplasia) or malignant (4 with endometrioid adenocarcinoma) lesions. In addition, 16 patients (30.8%) had other endometrial pathologic features. The 9 patients with premalignant or malignant endometrial lesions (8 white, 1 black) were overweight or obese; 3 of the patients did not have any clinical symptoms. All 4 patients with endometrioid adenocarcinoma had negative Lynch syndrome screening findings. CONCLUSIONS Our results suggest that it is important to recognize the presence of atypical endometrial cells in the Pap tests from young patients, given its association with the finding of premalignant and malignant pathologic features in subsequent endometrial biopsies.

Primary squamous cell carcinoma of the endometrium associated with human papilloma virus in a young woman: a case report. J Med Case Rep 2019; 13:167. [PMID: 31151475 PMCID: PMC6545029 DOI: 10.1186/s13256-019-2098-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2019] [Accepted: 04/26/2019] [Indexed: 11/20/2022] Open
Abstract
Background Primary squamous cell carcinoma of the endometrium is an extremely rare tumor with poorly understood pathogenesis. Case presentation We report a case of a 28-year-old Togolese woman who had consulted for vaginal bleeding and pelvic pain. Ultrasound showed thickening of the lining of the endometrium, and biopsy curettage was done. Anatomopathological examination was noteworthy for a proliferation of squamous cells often connected by union bridges arranged in tumor lobules with dyskeratotic maturation. Immunohistochemistry showed epithelial membrane antigen positivity, anti-pancytokeratin 1 markers of tumor cells positivity, chromogranin A negativity, actin negativity, S100 negativity, estrogen receptor negativity, and progesterone receptor negativity. In situ hybridization had objectified human papillomavirus genotypes 16/18. The diagnosis of primary squamous cell carcinoma of the endometrium associated with human papilloma virus was retained. A hysterectomy was performed, and the tumor was classified pT1N0M0. Conclusion The pathogenesis of this endometrial cancer is complex, and its association with human papillomavirus does not explain its genesis.

Endometrial scratching for infertile women undergoing a first embryo transfer: a systematic review and meta-analysis of published and unpublished data from randomized controlled trials. Fertil Steril 2019; 111:734-746.e2.

Abstract
OBJECTIVE To investigate endometrial scratch injury (ESI) as an intervention to improve IVF outcome in women undergoing a first ET. DESIGN Systematic review and meta-analysis. SETTING Not applicable. PATIENT(S) Infertile women undergoing a first fresh/frozen embryo transfer. INTERVENTION(S) We included published and unpublished data from randomized controlled trials in which the intervention group received ESI and controls received placebo or no intervention. Pooled results were expressed as relative risk (RR) with 95% confidence interval (CI). The review protocol was registered in PROSPERO to start the data extraction (CRD42018087786). MAIN OUTCOME MEASURE(S) Ongoing pregnancy/live birth rate (OPR/LBR), clinical pregnancy rate (CPR), multiple pregnancy rate (MPR), miscarriage rate (MR), and ectopic pregnancy rate (EPR). RESULT(S) Seven studies were included (1,354 participants). We found a nonsignificant difference between groups in terms of OPR/LBR, CPR, MR, MPR, and EPR. Subgroup analysis found that ESI on the day of oocyte retrieval (achieved by a Novak curette) reduced OPR/LBR (RR 0.31, 95% CI 0.14-0.69) and CPR (RR 0.36, 95% CI 0.18-0.71), whereas ESI during the cycle preceding ET (performed through soft devices) had no effect on OPR/LBR and CPR. No difference in the impact of ESI was observed between fresh and frozen embryo transfer. CONCLUSION(S) Current evidence does not support performing ESI with the purpose of improving the success of a first ET attempt.

Assessment of uterine luminal pH in mares and the effect of dilute vinegar lavage on uterine luminal pH and endometrial health. Theriogenology 2018; 117:7-15. [PMID: 29807257 DOI: 10.1016/j.theriogenology.2018.05.014] [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: 11/28/2017] [Revised: 05/11/2018] [Accepted: 05/13/2018] [Indexed: 11/22/2022]
Abstract
Uterine luminal pH has been demonstrated to be a valid indicator of uterine health in species such as cattle and sheep. However, research regarding uterine luminal pH in equines is lacking. The objectives of this study were to assess uterine luminal pH in mares during the estrous cycle, and evaluate the effect of dilute vinegar lavage on both uterine luminal pH and endometrial health. The study was conducted using a randomized block design in which eight mares (four Thoroughbred and four Standardbred) were aged matched then randomly assigned to two groups. Endometrial biopsies were taken from each mare prior to trial commencement. The treatment group (n = 4; 1 Thoroughbred, 3 Standardbreds) received a uterine lavage of one liter dilute vinegar (20 mL of vinegar in 1 L saline) every second day during each estrus period throughout the trial. Control group mares did not receive a uterine lavage. Uterine luminal pH measurements were recorded in all mares in both groups for a period of up to 10 min immediately prior to lavage (0 h), one hour and 24 h post lavage (same time points in control group mares as if they had been treated). Diestrus uterine luminal pH measurements were recorded once between days 6-10 post-ovulation. Endometrial biopsies were repeated from all mares at trial completion. Mean uterine luminal pH ranged from pH 5.3 to 7.6 and was significantly lower during diestrus compared to estrus (P < 0.001). Regression analysis indicated that this variation in pH was best explained by estrous cycle day, with uterine luminal pH increasing by a mean of 0.03 units each day (P < 0.001) from 6 to 10 days post-ovulation through to ovulation. Uterine lavage with dilute vinegar did not significantly affect uterine luminal pH (P > 0.05). A scoring system to quantify the abundance of cell types in the endometrial biopsies showed that mares in the treatment group had a significant decrease in polymorphonuclear cell abundance between pre- and post-trial biopsies (P = 0.03). Mares in the treatment group also had a significant decrease in lymphocyte, plasma cell and eosinophil cell abundance (P = 0.05). Although dilute vinegar lavage was not associated with a significant change in uterine luminal pH, it was associated with a significant improvement in endometrial biopsy scores. Because the control group did not receive a uterine lavage, further research is required to determine if this significant improvement results from the addition of dilute vinegar, or the uterine lavage itself.

Abstract
Genital tuberculosis is usually diagnosed in young women being assessed for infertility. After menopause it usually presents with symptoms resembling endometrial malignancy, such as postmenopausal bleeding, persistent vaginal discharge and pyometra. The diagnosis is made by detection of acid-fast bacilli on microscopy or bacteriological culture and/or presence of epithelioid granuloma on biopsy. Anti-tubercular therapy involves the use of rifampicin, isoniazid, pyrazinamide and ethambutol. Surgery is indicated if a pelvic mass and recurrence of pain or bleeding persist after 9 months of treatment. Three cases of genital tuberculosis in postmenopausal women with different clinical presentations are reported. The first woman presented with ascites and weight loss. The second had postmenopausal bleeding with a pipelle biopsy suggestive of endometrial intraepithelial neoplasia. The third presented with weight loss and a palpable abdominal mass. Pelvic malignancy was initially suspected but a diagnosis of tuberculosis was made following pre-operative endometrial biopsy, bacteriological culture and intra-operative frozen section. All three women responded to anti-tubercular therapy.

Abstract
OBJECTIVE To evaluate the efficacy of cervical lidocaine gel in reducing patient discomfort during Pipelle endometrial sampling. MATERIALS AND METHODS From September 2012 to January 2013, 137 patients were evaluated with Pipelle endometrial biopsy. For group 1 (77 women), 2% lidocaine gel was applied to the cervical canal 3 min before endometrial sampling. For group 2 (60 women), a placebo gel was applied. The pain experienced by the patients during biopsy was evaluated using a 100 mm visual analog scale. RESULTS The pain score was significantly lower during suction curettage (T3) in the group 1 than in the group 2. There was no significant difference between the groups in terms of pain score in other stages of the procedure (2.6±1.3 and 4.5±1.4; p=0.03). CONCLUSION Cervical 2% lidocaine gel is simple and effective for decreasing pain associated with Pipelle endometrial biopsy.

Abstract
STUDY OBJECTIVE To evaluate the prevalence and impact of chronic endometritis (CE) in patients with intrauterine adhesions (IUAs). DESIGN Prospective cohort study (Canadian Task Force classification II-2). SETTING University-affiliated hospital. PATIENTS Eighty-two women with moderate to severe IUAs. INTERVENTIONS Transcervical resection of adhesions (TCRA) and endometrial biopsy were performed in all patients. According to results of the endometrial biopsy, participants were classified into 2 groups: 29 patients with CE (CE group) and 53 women without CE (NCE group). Second-look hysteroscopy assessed the impact of TCRA using the American Fertility Society classification system. MEASUREMENTS AND MAIN RESULTS Prevalence of CE, reformation of adhesions, and reduction of adhesion score were studied. Thirty-one women (37.8%) presented with visual signs of CE at hysteroscopy, confirmed by histology in 29 of 82 patients (35.4%). In hysteroscopic diagnosis of CE, sensitivity and specificity were 79.3% (23/29) and 84.9% (45/53), respectively. At second-look hysteroscopy, the recurrence of adhesions in the CE group was significantly higher than in the NCE group (44.8% vs 20.8%, respectively; p = .022). The median reduction of adhesion score was significantly greater in the NCE group (median, 8; range, 0-12) than in the CE group (median, 5; range, 0-10). CONCLUSION CE in women with IUAs may be a contributing factor in higher adhesion recurrence, indicating chronic inflammation may play a role in IUA recurrence.

Exosome-like vesicles in uterine aspirates: a comparison of ultracentrifugation-based isolation protocols. J Transl Med 2016; 14:180. [PMID: 27317346 PMCID: PMC4912787 DOI: 10.1186/s12967-016-0935-4] [Citation(s) in RCA: 59] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2016] [Accepted: 06/02/2016] [Indexed: 01/05/2023] Open
Abstract
Background Uterine aspirates are used in the diagnostic process of endometrial disorders, yet further applications could emerge if its complex milieu was simplified. Exosome-like vesicles isolated from uterine aspirates could become an attractive source of biomarkers, but there is a need to standardize isolation protocols. The objective of the study was to determine whether exosome-like vesicles exist in the fluid fraction of uterine aspirates and to compare protocols for their isolation, characterization, and analysis. Methods We collected uterine aspirates from 39 pre-menopausal women suffering from benign gynecological diseases. The fluid fraction of 27 of those aspirates were pooled and split into equal volumes to evaluate three differential centrifugation-based procedures: (1) a standard protocol, (2) a filtration protocol, and (3) a sucrose cushion protocol. Characterization of isolated vesicles was assessed by electron microscopy, nanoparticle tracking analysis and immunoblot. Specifically for RNA material, we evaluate the effect of sonication and RNase A treatment at different steps of the protocol. We finally confirmed the efficiency of the selected methods in non-pooled samples. Results All protocols were useful to isolate exosome-like vesicles. However, the Standard procedure was the best performing protocol to isolate exosome-like vesicles from uterine aspirates: nanoparticle tracking analysis revealed a higher concentration of vesicles with a mode of 135 ± 5 nm, and immunoblot showed a higher expression of exosome-related markers (CD9, CD63, and CD81) thus verifying an enrichment in this type of vesicles. RNA contained in exosome-like vesicles was successfully extracted with no sonication treatment and exogenous nucleic acids digestion with RNaseA, allowing the analysis of the specific inner cargo by Real-Time qPCR. Conclusion We confirmed the existence of exosome-like vesicles in the fluid fraction of uterine aspirates. They were successfully isolated by differential centrifugation giving sufficient proteomic and transcriptomic material for further analyses. The Standard protocol was the best performing procedure since the other two tested protocols did not ameliorate neither yield nor purity of exosome-like vesicles. This study contributes to establishing the basis for future comparative studies to foster the field of biomarker research in gynecology.

Abstract
Background Even in the face of a substantial increase in the numbers of endometrial cancer cases and in the numbers of women who have risk factors, there is no clear agreement about the indications for assessing the endometria of women with abnormal bleeding or about the tools to use in that assessment. This study sought to determine in a group of high risk women with abnormal uterine bleeding, the probability that an outpatient endometrial aspiration would identify significant pathology. Methods Retrospective cohort study of the histology from endometrial aspirations performed from 2001 to 2008 for abnormal uterine bleeding at Harbor-UCLA Medical Center and its satellite public health clinics. Medical records were reviewed in detail to assess risk factors, descriptions of bleeding abnormalities and histologic results. Results The charts of 1601 women who underwent 1636 endometrial biopsies for a wide variety of abnormal uterine bleeding patterns yielded 73 (4.6 %) cases of endometrial carcinoma, 43 cases of atypical endometrial hyperplasia (2.7 %), for an overall yield of significant pathology of 7.2 %. Hyperplasia without atypia was found in another 83 cases (5.2 %). Obesity, diabetes and postmenopausal age are associated with an increased risk of significant pathology. Bleeding patterns were so poorly documented that analysis of yield by this factor should be viewed with caution. Conclusions The probability of detecting significant uterine pathology is greatest among obese, diabetic postmenopausal women with diabetes (26.3 %). Conversely, the probability of identifying significant pathology in younger women without risk factors is less than 2 %. For women who perceive their individualized risk estimate to be too small to justify an endometrial biopsy, it may be possible to offer oral higher dose progestin therapy on the condition that persistent abnormal bleeding will require more intensive evaluation. These estimates of absolute risk of being diagnosed with significant pathology on endometrial biopsy may be helpful to patients as they consider giving informed consent for the procedure.

Abstract
Implantation failure is considered as a major cause of infertility in women with recurrent pregnancy loss (RPL) and in otherwise healthy women with unexplained infertility. Preliminary data in primates suggested that relaxin (RLX) is involved in endometrial preparation for implantation. In a prospective observational study, the endometrial RLX receptor (LGR7) expression was assessed in three groups of patients with regular ovulatory cycle and normal uterine cavity: 23 with RPL (Group A), 23 with unexplained infertility undergone at least three cycles of failed in vitro fertilization (IVF) reporting good oocyte and embryo quality (Group B), 23 with proven fertility (Group C). Assessment of LGR7 expression was performed with both polymerase chain reaction (PCR) analysis and immunohistochemistry on endometrial samples obtained with hysteroscopic biopsy performed in the secretory phase of the menstrual cycle. Endometrial LGR7 was less expressed in group A and B versus C, both by PCR analysis (p = 0.024) and immunohistochemistry. The decreased expression of the endometrial RLX receptor in women with implantation failures, both in vitro fertilization failure and recurrent pregnancy loss, suggests that RLX may play a crucial role in the structural and functional changes of the endometrium during the window of implantation.

The impact of low-volume uterine lavage on endometrial biopsy classification. Theriogenology 2016; 86:1004-1007. [PMID: 27118385 DOI: 10.1016/j.theriogenology.2016.03.028] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2015] [Revised: 03/14/2016] [Accepted: 03/17/2016] [Indexed: 11/23/2022]
Abstract
In the mare, the low-volume uterine lavage technique allows for bacterial sampling of the entire uterine lumen and is usually performed after obtaining the traditional double-guarded endometrial swab for aerobic culture and cytology and before procurement of an endometrial biopsy sample during a breeding soundness examination. The purpose of this study was to explore the potential effects of the low-volume lavage on the endometrial biopsy classification and polymorphonuclear cell (PMNs) infiltration in the context of a breeding soundness examination. Fourteen light horse mares of mixed breed, age 7 to 21 years, with known reproductive history, were included in the study, matched by age and reproductive history, and then divided into treatment and control groups. Transrectal palpation and ultrasonography, endometrial swabbing, and the first endometrial biopsy were performed in all mares. Low-volume uterine lavage was performed in the treatment group but not the control group. After either the lavage or a 15-minute rest, a second endometrial biopsy was obtained from both the control and treatment groups. Endometrial swabs and effluent from the low-volume lavages were submitted for aerobic culture and sensitivity. Biopsy samples were fixed in Bouin's solution for 24 hours, processed, stained with hematoxylin and eosin, and then viewed under bright light microscopy. Additional staining with anti-neutrophil elastase antibody (ab68672) was performed for indirect immunohistochemistry. All samples were interpreted by a blinded observer. When the first (pre-uterine lavage) and second (post-uterine lavage) biopsies were compared using a mixed-effects logistic regression, there was no difference in endometrial biopsy classification (P = 0.74), presence of PMNs in blood vessels (P = 0.728), or infiltration of PMNs in the tissue (P = 0.934) between the treatment and control groups. In this study, the low-volume uterine lavage did not affect the endometrial biopsy classification.

An investigation of the microbiota in uterine flush samples and endometrial biopsies from dairy cows during the first 7 weeks postpartum. Theriogenology 2016; 86:642-50.

Abstract
Metritis and endometritis commonly occur in dairy cows after calving. Although numerous studies have been performed to identify the causative pathogens, a complete overview has not been done. Metagenomic studies have analyzed the bacterial populations of uterine flush samples from postpartum (pp) dairy cows, but the microbiota in the uterine luminal fluid may differ from the microbiota of the endometrium itself, and important putative pathogens may have been overlooked. In the present study, we compared the microbiota of the uterine lumen and the endometrium of healthy, metritic, and endometritic cows. Samples were collected from 68 Holstein dairy cows at 1, 4, and 7 weeks pp, and the data were analyzed by deep sequencing of the V1 and V2 hypervariable regions of the 16S ribosomal RNA gene. The results showed that Porphyromonadaceae, Fusobacteriaceae, Leptotrichiaceae, and Mycoplasmataceae may be associated with uterine disease. The microbiota of the uterine flush samples and the endometrial biopsies were correlated, but the microbiota of the biopsies was more diverse. Fusobacteriaceae and Leptotrichiaceae were not observed in the biopsies at week 7, whereas they accounted for 20% and 13%, respectively, of the bacterial populations in the flush samples. The Mycoplasmataceae family was observed in much higher quantity in the flush samples than in the biopsies of the endometritis groups at weeks 4 and 7. Our findings support the observations of previous metagenomic studies and illustrate the importance of including endometrial biopsies to obtain more detailed knowledge of the pp uterine microbiota.

Abstract
Female genital tuberculosis (FGTB) is an important cause of significant morbidity, short- and long-term sequelae especially infertility whose incidence varies from 3 to 16 % cases in India. Mycobacterium tuberculosis is the etiological agent for tuberculosis. The fallopian tubes are involved in 90-100 % cases, endometrium is involved in 50-80 % cases, ovaries are involved in 20-30 % cases, and cervix is involved in 5-15 % cases of genital TB. Tuberculosis of vagina and vulva is rare (1-2 %). The diagnosis is made by detection of acid-fast bacilli on microscopy or culture on endometrial biopsy or on histopathological detection of epithelioid granuloma on biopsy. Polymerase chain reaction may be false positive and alone is not sufficient to make the diagnosis. Laparoscopy and hysteroscopy can diagnose genital tuberculosis by various findings. Treatment is by giving daily therapy of rifampicin (R), isoniazid (H), pyrazinamide (Z) and ethambutol (E) for 2 months followed by daily 4 month therapy of rifampicin (R) and isoniazid (H). Alternatively 2 months intensive phase of RHZE can be daily followed by alternate day combination phase (RH) of 4 months. Three weekly dosing throughout therapy (RHZE thrice weekly for 2 months followed by RH thrice weekly for 4 months) can be given as directly observed treatment short-course. Surgery is rarely required only as drainage of abscesses. There is a role of in vitro fertilization and embryo transfer in women whose fallopian tubes are damaged but endometrium is healthy. Surrogacy or adoption is needed for women whose endometrium is also damaged.

Abstract
Office-based endometrial sampling is the most frequently performed gynaecological procedure. The procedure is usually associated with pain and discomfort. Several anaesthetic and analgesic techniques (e.g., non-steroidal anti-inflammatory drugs, paracervical block, misoprostol and topical anaesthetics) are used for pain management during endometrial sampling. There is no comprehensive study using lidocaine in spray form; we sought to investigate the analgesic efficacy of 10% lidocaine spray in patients undergoing office-based endometrial biopsy. We conducted a prospective, randomised (lidocaine spray (n = 60) and placebo (n = 60), respectively), double-blind study. The mean pain score during procedure was 3.51 ± 1.51 in the lidocaine spray group and 5.11 ± 1.66 in the placebo group. Lidocaine spray treatment significantly lowered the pain scores compared with placebo (p < 0.001). Lidocaine spray can be accepted as a non-invasive, easy to apply and more comfortable anaesthetic method for office-based endometrial sampling.

Abstract
OBJECTIVES To describe the effect of combined oral contraceptives (COCs) on matrix metalloproteinases MMP-2 and MMP-9 activity and compare MMP activity in women taking a COC with or without doxycycline. STUDY DESIGN Subjects (n=20) underwent endometrial biopsies (1) in the late luteal phase of a baseline cycle prior to initiating COCs, (2) on days 19-21 while taking COCs in a standard 28-day cycle (7-day hormone-free interval) and (3) on days 26-28 while taking active COCs continuously for a 28-day cycle. During the continuous COC cycle, they were randomized to receive daily subantimicrobial dose doxycycline 40mg or placebo. RESULTS Compared to baseline, COC treatment increased MMP-2 (p<.001) and MMP-9 (p<.001). MMP activity was lower in subjects taking a COC with doxycycline compared to those receiving placebo although only significantly lower for MMP-2 latent form (p=.002). CONCLUSIONS Unscheduled bleeding with COCs may be the result of increased endometrial MMPs. Sample size limitations prevent us from determining how doxycycline affects MMP activity in COC users.

Abstract
OBJECTIVE To assess the availability and capacity of US-based integrated centers for the management of Lynch syndrome. METHODS A cross-sectional survey of practice patterns in the care of patients with Lynch syndrome was conducted at 33 National Cancer Institute-designated cancer centers in the USA from March 1 to June 1, 2013. Each cancer center was contacted by telephone and the caller used a uniform scripted greeting and survey format. RESULTS All centers routinely recommended colonoscopy. Other recommended screening modalities were hysterectomy and bilateral salpingo-oophorectomy (29/33; 88%), endoscopy (27/33; 82%), urinalysis (23/33; 70%), endometrial sampling (21/33; 64%), dermatologic examination (19/32; 59%), pelvic ultrasonography (18/33; 55%), serum CA125 level (14/33; 42%), urine cytology (14/33; 42%), computed tomography (1/33; 3%), and magnetic resonance imaging (1/33; 3%). Each center had a multidisciplinary team but the composition varied. A designated team leader was present at 21 centers (64%). Having a team leader was associated with an increased likelihood of recommending endoscopy (P=0.04) and dermatologic surveillance (P=0.01). Only 23 centers (70%) had a system in place for communicating follow-up with patients. CONCLUSION The lack of consensus in practice patterns recorded among participating centers probably reflected the limited existing evidence on the usefulness of most screening modalities.

Abstract
After their retirement from sports, performance mares often show a poor breeding success. The objective of this study was the microscopic evaluation of endometrial biopsies of retired sports mares (n = 189) to search for alterations that may explain subfertility. Mares of this study aged 3-23 years showed endometritis (30%) and endometrosis (77%); mild forms predominated. In regard to those mares biopsied during the breeding season (n = 99), 50% had glandular differentiation disorders, i.e. glandular inactivity (8%) or irregular glandular differentiation (42%). Compared to literature data retrieved from mainly non-performance mares, the sports mares of this study showed a similar prevalence of endometrosis and endometritis, but a much higher prevalence of glandular differentiation disorders. The most common cause of the latter is an ovarian dysfunction. Results of this study indicate an association between glandular maldifferentiation of the endometrium and the clinically observed reduced fertility of retired sports mares.

Abstract
OBJECTIVE Endometrial biopsy (EMBx) and colonoscopy performed under the same sedation is termed combined screening and has been shown to be feasible and to provide a less painful and more satisfactory experience for women with Lynch syndrome (LS). However, clinical results of these screening efforts have not been reported. The purpose of this study was to evaluate the long-term clinical outcomes and patient compliance with serial screenings over the last 10.5 years. METHODS We retrospectively analyzed the data for 55 women with LS who underwent combined screening every 1-2 years between 2002 and 2013. Colonoscopy and endometrial biopsy were performed by a gastroenterologist and a gynecologist, with the patient under conscious sedation. RESULTS Out of 111 screening visits in these 55 patients, endometrial biopsies detected one simple hyperplasia, three complex hyperplasia, and one endometrioid adenocarcinoma (FIGO Stage 1A). Seventy-one colorectal polyps were removed in 29 patients, of which 29 were tubular adenomas. EMBx in our study detected endometrial cancer in 0.9% (1/111) of surveillance visits, and premalignant hyperplasia in 3.6% (4/111) of screening visits. No interval endometrial or colorectal cancers were detected. CONCLUSIONS Combined screening under sedation is feasible and less painful than EMBx alone. Our endometrial pathology detection rates were comparable to yearly screening studies. Our results indicate that screening of asymptomatic LS women with EMBx every 1-2 years, rather than annually, is effective in the early detection of (pre)cancerous lesions, leading to their prompt definitive management, and potential reduction in endometrial cancer.

Abstract
PURPOSE To assess the relevance of MRI, endometrial biopsy and curettage in the diagnosis of endometrial cancer at high risk of lymph node metastasis. PATIENTS AND METHODS A retrospective study on continuous series of patients treated for endometrial cancer limited to the uterus between 2004 and 2008, results of preoperative evaluation of tumor stage using MRI, histological type and grade by endometrial curettage and biopsies were compared to final histological examination. RESULTS One hundred and sixty-nine patients were included in the study. Ninety (53.3%) had MRI, 112 (66.2%) curettage and 61 (36.6%) endometrial biopsy using Pipelle de Cornier. Sensibility (SN), specificity (SP), positive (PPV) and negative predictive values (NPV) of MRI, in the diagnosis of endometrial cancer at high risk of lymph nodes metastases were of 65.6%, 87.2%, 77.7%, 79.2%. For EB and curettage SN, SP, PPV and NPV were of 42.9%, 96.9%, 85%, 79.5%; 80.6%, 98.3%, 96.2% and 90.6% respectively. 37.8% of cancers diagnosed to be at low risk of lymph node metastasis were at high risk in definitive histologic examination. DISCUSSION AND CONCLUSION Preoperative evaluation by MRI, endometrial curettage and biopsy has good diagnostic value in the identification of endometrial cancer susceptible to benefit from lymphadenectomy. Underestimation, however, is encountered in approximately one third of cases.

Abstract
Morphologic criteria for distinguishing endometrial adenocarcinoma from complex atypical endometrial hyperplasia have been described previously, but they have not been examined extensively for their individual ability for predicting endometrial adenocarcinoma as determined by subsequent hysterectomy. We examined endometrial biopsies diagnosed in the spectrum of complex atypical endometrial hyperplasia to well-differentiated endometrial adenocarcinoma for various morphologic features that may be predictive for the presence of myoinvasive endometrial adenocarcinoma in subsequent hysterectomy. Cases diagnosed as FIGO grade I endometrial adenocarcinoma or complex atypical endometrial hyperplasia in endometrial biopsies seen at New York University Medical Center from 2003 to 2006 were analyzed for the presence of various morphologic features without the knowledge of hysterectomy findings. Only those cases with subsequent hysterectomy were included in the study. The data were analyzed to identify features with high specificity for a finding of myoinvasive endometrial adenocarcinoma in subsequent hysterectomy. Extreme glandular crowding (95% or greater area with glands, aggregate size 3 mm or greater) and cribriform foci of any size were found to have high sensitivity and specificity for the finding of myoinvasive carcinoma in subsequent hysterectomy (P < .0001).

Abstract
BACKGROUND Genital tuberculosis is a common entity in gynecological practice particularly among infertile patients. It is rare in developed countries but is an important cause of infertility in developing countries. OBJECTIVE The present study has investigated the prevalence of female genital tract tuberculosis (FGT) among infertile patients, which was conducted at the Obstetrics and Gynecology Unit-I, Allied Hospital, affiliated with Punjab Medical College, Faisalabad, Pakistan. MATERIALS AND METHODS 150 infertile women who were referred to infertility clinic were selected randomly and enrolled in our study. Patients were scanned for possible presence of FGT by examination and relevant investigation. We evaluated various aspects (age, symptoms, signs, and socio-economic factors) of the patients having tuberculosis. RESULTS Very high frequency of FGT (20%) was found among infertile patients. While, a total of 25 patients out of 30 (83.33%) showed primary infertility and the remaining 5 cases (16.67%) had secondary infertility. Among secondary infertility patients, the parity ranged between 1 and 2. A total of 40% of patients (12 cases) were asymptomatic but infertile. Evidence of family history was found in 4 out of a total of 30 patients (13.3%), respectively. According to histopathological and bacteriological examination of endometrial biopsy and laparotomy, tuberculous endometritis was found in 20 out of a total of 25 (80%) cases, while tuberculous salpingitis and tuberculous oophoritis were found both in 2 (8%) of the cases, respectively. Only one case (4%) of tuberculosis cervicitis was found in the present study. CONCLUSION Although infertility is not a disease in classical sense, but it is an extremely important personal concern for many couples and a significant health problem for our profession. So, it is worthwhile to identify and evaluate the factors contributing to infertility.

Abstract
BACKGROUND Despite numerous developments in the field of assisted reproduction the implantation rate remains low .Recent studies suggested that local injury to endometrium in controlled ovarian hyper stimulation cycle improves implantation rate. Studies have attempted to intervene in the development of endometrium. OBJECTIVE The aim of the present study was the exploration of the possibility that local injury of the endometrium increases implantation rate. MATERIALS AND METHODS In this interventional study, 100 good responders to hormone stimulation patients were divided into control group (n=50) and experimental group (n=50) which undergo endometrial biopsy by biopsy catheter )piplle) on day 21 of their previous menstrual cycle with use of contraceptive pills before the IVF-ET treatment. In total, 26 patients were removed from the study because the number of stimulated follicles were below 3, or there was no embryo or there was the risk of OHSS. The remaining patients were 33 in experimental group and 41 in the control group. RESULTS There were no significant differences between the two groups in terms of the age of the patients, duration of infertility and BMI, base line FSH level and responses to hormone stimulation. The rates of embryo implantation, chemical and clinical pregnancy in the experimental group were 4.9%, 18.2% and 12.1% with no significant differences with the control group (6.7%, 19.5%, 17.1%). Cancellation rate was 26%. CONCLUSION In our study, endometrial biopsy didn't increase the chances to conceive at the following cycle of treatment.
