Abstract
OBJECTIVE The primary objective of this clinical practice guideline is to provide gynaecologists with an algorithm and evidence to guide the diagnosis and management of endometrial polyps. TARGET POPULATION All patients with symptomatic or asymptomatic endometrial polyps. OPTIONS Options for management of endometrial polyps include expectant, medical, and surgical management. These will depend on symptoms, risks for malignancy, and patient choice. OUTCOMES Outcomes include resolution of symptoms, histopathological diagnosis, and complete removal of the polyp. BENEFITS, HARMS, AND COSTS The implementation of this guideline aims to benefit patients with symptomatic or asymptomatic endometrial polyps and provide physicians with an evidence-based approach toward diagnosis and management (including expectant, medical, and surgical management) of polyps. EVIDENCE The following search terms were entered into PubMed/Medline and Cochrane: endometrial polyps, polyps, endometrial thickening, abnormal uterine bleeding, postmenopausal bleeding, endometrial hyperplasia, endometrial cancer, hormonal therapy, female infertility. All articles were included in the literature search up to 2021 and the following study types were included: randomized controlled trials, meta-analyses, systematic reviews, observational studies, and case reports. Additional publications were identified from the bibliographies of these articles. Only English-language articles were reviewed. VALIDATION METHODS The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See Appendix A (Tables A1 for definitions and A2 for interpretations of strong and weak recommendations). INTENDED AUDIENCE Gynaecologists, family physicians, registered nurses, nurse practitioners, medical students, and residents and fellows. TWEETABLE ABSTRACT Uterine polyps are common and can cause abnormal bleeding, infertility, or bleeding after menopause. If patients don't experience symptoms, treatment is often not necessary. Polyps can be treated with medication but often a surgery will be necessary. SUMMARY STATEMENTS RECOMMENDATIONS.

Abstract
OBJECTIVE To present a new technique for complete endometrial polypectomy, using the bipolar loop hysteroscope, but without the activation of electrical energy, and follow its efficiency and safety for the patient. STUDY DESIGN This is a prospective descriptive study conducted at a university hospital. Forty four patients were recruited to the study according to an intra uterine polyp diagnosed by transvaginal ultrasound (TVS). Out of them 25 really had an endometrial polyp which was inspected by hysteroscopy. Eighteen were at menopause age and seven in their reproductive age. The hysteroscopic removal of the endometrial polyp was performed using the operative loop resectoscope without using electricity, meaning by cold loop. We called this unique technique SHEPH: Shaving of Endometrial Polyp by Hysteroscopy. RESULTS The range age was 21-77 years old. All patients with apparently endometrial polyp, underwent a complete removal of the polyp which could be directly seen through hysteroscopy. No bleeding was seen in all cases. The other nineteen patients had normal uterine cavity, so a biopsy was taken according to the indication. The specimen from all cases were sent to histological evaluation. An endometrial polyp was histologically confirmed in all cases who underwent the SHEPH technique, while fragments of an endometrial polyp was revealed by histology in six cases from the group that had normal uterine cavity. No complications were noted for the short and long periods. CONCLUSIONS Nonelectric Shaving of Endometrial Polyp by Hysteroscopy (SHEPH technique) is a safe and effective procedure which allows the surgeon to achieve a complete endometrial polypectomy but without using electrical energy within the body of the patient. The technique which is easy to learn, is new and unique by eliminate thermal damage in a very common gynecologic indication.

J Clin Med 2022; 11:jcm11195836. [PMID: 36233703 PMCID: PMC9570961 DOI: 10.3390/jcm11195836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 09/28/2022] [Accepted: 09/28/2022] [Indexed: 11/08/2022] Open
Abstract
INTRODUCTION We undertook a literature review of the use of levonorgestrel-releasing intrauterine devices when utilized for heavy menstrual bleeding and/or dysmenorrhea. METHODS A narrative review of articles in the Scopus and Medline databases was conducted. RESULTS A number of options exist for the management of both abnormal uterine bleeding (AUB) and dysmenorrhea, and evidence is accumulating that the insertion of a levonorgestrel-releasing intrauterine system (LNG-IUS) represents a useful option for their long-term treatment. The idea of using a progestogen released in utero was initially conceived to achieve long-term contraception, but it was quickly found that these systems could be utilized for a number of therapeutic applications. The first device to be made commercially available, Progestasert, was withdrawn from the market because, in the event of contraceptive failure, it caused a disproportionate percentage of extrauterine pregnancies. On the other hand, the LNG-IUS continues to be successfully utilized in its various variants, releasing 20, 13, or 8 μg/day. These devices have a respective duration of action of 7 (possibly 8), 5, and 3 years, and there exist versions of frameless systems affixed to the myometrium of the uterine fundus. In the present review, following a brief description of the major causes of AUB and dysmenorrhea, the molecular bases for the use of the LNG-IUS are summarized. This is followed by a compendium of its use in AUB and dysmenorrhea, concluding that the insertion of the system improves the quality of life, reduces menstrual blood loss better than other medical therapies, and decreases the extent of dysmenorrhea and pelvic pain. In addition, there is no evidence of a significant difference in these outcomes when the use of the LNG-IUS was compared with improvements offered by endometrial ablation or hysterectomy. Possibly, the most important mechanism of action of the system consists of its ability to induce amenorrhea, which effectively eliminates heavy bleeding and dysmenorrhea. However, no method is ideal for every woman, and, in the case of the LNG-IUS, younger age and severe dysmenorrhea seem to be associated with a higher risk of discontinuation. CONCLUSION The higher-dose LNG-IUS is a useful tool for HMB and dysmenorrhea in women of all ages. The low cost and ease of use make the LNG-IUS an attractive option, especially when contraception is also desired.

Effect of Hysteroscopic Polypectomy Combined with Mirena Placement on Postoperative Adverse Reactions and Recurrence Rate of Endometrial Polyps: Based on a Large-Sample, Single-Center, Retrospective Cohort Study. BIOMED RESEARCH INTERNATIONAL 2022; 2022:1232495. [PMID: 35528176 PMCID: PMC9071880 DOI: 10.1155/2022/1232495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 03/22/2022] [Accepted: 03/28/2022] [Indexed: 11/17/2022]
Abstract
Objective. To investigate the effect of hysteroscopy surgery combined with Mirena on postoperative adverse reactions and recurrence rate of endometrial polyps (EP). Methods. A total of 312 patients who underwent hysteroscopic polypectomy of EP in our hospital from June 2017 to November 2020 were enrolled retrospectively. Among them, 42 patients did not take any treatment after the operation (control group), 156 patients were treated with levonorgestrel intrauterine birth control system (Mirena group), and 114 patients were treated with oral spironolone ethinylestradiol tablets (oral group). The clinical data of 312 patients were recorded and followed up regularly. All patients were followed up through an outpatient clinic or telephone to 12 months after the operation. The patients’ age, disease course, number of pregnancies, clinical manifestations, endometrial thickness before the operation, duration of operation, amount of bleeding during the operation, and number and size of polyps were analyzed. The recurrence and postoperative side effects of EP in the three groups were followed up within 12 months after the operation. Results. There was no significant difference in endometrial thickness among the three groups before treatment (
). After 3 months, 6 months, and 12 months of treatment, the endometrial thickness of the three groups decreased, while the decrease in the Mirena group and the oral group was better compared to the control (
). The decrease in the Mirena group was better than that in the oral group (
). There was no significant difference in hemoglobin levels among the three groups before treatment (
). After 3, 6, and 12 months of treatment, the hemoglobin levels of the three groups increased to varying degrees, while the levels of the Mirena group and oral group were better compared to the control (
). Three months after the operation, the improvement of clinical symptoms was similar in the three groups, and there was no significant difference among the three groups (
). At 6 and 12 months after the operation, the improvement of clinical symptoms in the oral group and Mirena group was better compared to the control group (
), but there was no significant difference between the oral group and Mirena group (
). After the operation, some patients had complications such as lower abdominal pain, breast distension pain, irregular vaginal bleeding, and abnormal liver function. There was no significant difference in the number of complications among the three groups (
). During the follow-up to 12 months after the operation, the recurrence rate in the oral group and Mirena group was lower compared to the control (
), and the recurrence rate in the Mirena group was lower than that in the oral group (
). Conclusion. Placing Mirena immediately after hysteroscopic polypectomy of EP can reduce the recurrence rate of endometrial polyps, increase the level of hemoglobin, and reduce the thickness of the endometrium, which can be employed and popularized according to the condition of patients in clinical work.

Hum Reprod Update 2021; 28:153-171. [PMID: 34875046 PMCID: PMC8888994 DOI: 10.1093/humupd/dmab039] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Revised: 10/15/2021] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND Human endometrium remains a poorly understood tissue of the female reproductive tract. The superficial endometrial functionalis, the site of embryo implantation, is repeatedly shed with menstruation, and the stem cell-rich deeper basalis is postulated to be responsible for the regeneration of the functionalis. Two recent manuscripts have demonstrated the 3D architecture of endometrial glands. These manuscripts have challenged and replaced the prevailing concept that these glands end in blind pouches in the basalis layer that contain stem cells in crypts, as in the intestinal mucosa, providing a new paradigm for endometrial glandular anatomy. This necessitates re-evaluation of the available evidence on human endometrial regeneration in both health and disease in the context of this previously unknown endometrial glandular arrangement. OBJECTIVE AND RATIONALE The aim of this review is to determine if the recently discovered glandular arrangement provides plausible explanations for previously unanswered questions related to human endometrial biology. Specifically, it will focus on re-appraising the theories related to endometrial regeneration, location of stem/progenitor cells and endometrial pathologies in the context of this recently unravelled endometrial glandular organization. SEARCH METHODS An extensive literature search was conducted from inception to April 2021 using multiple databases, including PubMed/Web of Science/EMBASE/Scopus, to select studies using keywords applied to endometrial glandular anatomy and regeneration, and the references included in selected publications were also screened. All relevant publications were included. OUTCOMES The human endometrial glands have a unique and complex architecture; branched basalis glands proceed in a horizontal course adjacent to the myometrium, as opposed to the non-branching, vertically coiled functionalis glands, which run parallel to each other as is observed in intestinal crypts. This complex network of mycelium-like, interconnected basalis glands is demonstrated to contain endometrial epithelial stem cells giving rise to single, non-branching functionalis glands. Several previous studies that have tried to confirm the existence of epithelial stem cells have used methodologies that prevent sampling of the stem cell-rich basalis. More recent findings have provided insight into the efficient regeneration of the human endometrium, which is preferentially evolved in humans and menstruating upper-order primates. WIDER IMPLICATIONS The unique physiological organization of the human endometrial glandular element, its relevance to stem cell activity and scarless endometrial regeneration will inform reproductive biologists and clinicians to direct their future research to determine disease-specific alterations in glandular anatomy in a variety of endometrial pathological conditions.

Abstract
Introduction: Most endometrial polyps represent focal hyperplasia of the endometrium. Endometrial polyps can be diagnosed by ultrasound, hysterocontrast sonography, hysterosalpingography, endometrial biopsy, and uterine curettage, but diagnostic hysteroscopy is considered the gold-standard method, with the greatest sensitivity and specificity and also with the opportunity for treatment at the same time.Study design: A retrospective study was conducted on 424 patients between 2006 and 2018. The polyps were verified during diagnostic hysteroscopy and were removed by resectoscopy or curettage. All samples underwent histological examination. The effectivity of the type of resection and the recurrence rate were evaluated.Results: The average age of the patients was 60.2 ± 9.3 years. Polyps were excised in 62.97% by resectoscopic polypectomy and in 37.03% by curettage. Malignancy was confirmed in 4.24% of cases. Histological verification of polyps was 79.4% in the resectoscopy group and 69.04% in the curettage group; the difference was significant (p < 0.01). The recurrence rate was 20.47% after resectoscopy and 27.12% following curettage.Conclusion: Hysteroscopy remains the best option and the gold-standard method among diagnostic procedures of endometrial pathology. In this study, there was a significant difference in matching hysteroscopic and histological findings in the two methods of polypectomy. The recurrence rate is also lower following resectoscopy.

Abstract
INTRODUCTION Thanks to the progress of science, it is now understood that a successful implantation not only depends on the quality of the embryo, but also on having a receptive endometrium. During the years, several authors have reviewed the important role of the uterine factor, ranging from the congenital anomalies, such as uterine septa and subsepta, and acquired conditions such as endometrial polyps and submucous myomas. Currently, hysteroscopy has proved to be a powerful and accurate tool for visualizing the uterine cavity and treating intrauterine pathologies. EVIDENCE ACQUISITION This review of the literature aims to report the current available data on the effects of the two most common endouterine pathologies (i.e. endometrial polyps and submucous myomas) and the impact of hysteroscopic removal on fertility outcomes. EVIDENCE SYNTHESIS To date, the low number of randomized controlled trials available does not yet make it possible to give a definitive answer on what are the reproductive outcomes following treatment of endometrial polyps and leiomyomas. Nevertheless, existing evidence points to a benefit of removal of this two pathologies in infertile women, mostly when they have a history of recurrent pregnancy loss. CONCLUSIONS Further studies are needed to demonstrate that surgical treatments of endometrial polyps and myomas could improve not only the morphology but also the function of the uterine cavity before undergoing any assisted fertility treatment.

Abstract
Obesity is associated with numerous diseases, including endometrial disorders in postmenopausal women, such as adenocarcinoma, hyperplasias and endometrial polyps, and the risk of malignant transformation of these structures. The present study evaluated the influence of body mass index (BMI) on cell proliferation (BCL2 and MKI67) in endometrial polyps in postmenopausal women. A prospective cross-sectional study using immunohistochemical analysis of the expression of a cell proliferation marker (MKI67) and an anti-apoptotic gene (BCL2) in endometrial polyps in postmenopausal women was performed. The patients were divided into three groups depending on BMI: i) <24.9 kg/m2 (normal); ii) >25 and <29.9 kg/m2 (overweight); and iii) >30 kg/m2 (obese). The present study analyzed the expression of these markers in relation to polyp size, histological type and time since menopause in 38 patients. The interpretation of MKI67 and BCL2 expression accounted for the percentage of positive cells (scores): 1 (weak), <5% of cells showed expression; 2 (moderate), between 5 and 50%; and 3 (intense), >50%. Statistical analysis was performed using GraphPad InStat version 3.00 software. ANOVA was used to analyze BCL2 and MKI67 expression. A significance level of P<0.05 was adopted for rejecting the null hypothesis. There was greater glandular expression of MKI67 in obese women than in normal weight women (P=0.02) and greater expression of BCL2 in the stroma of polyps >2 cm (P=0.03). Hyperplastic polyps exhibited hyperexpression of MKI67 (P=0.04) compared with atrophic polyps. No difference in MKI67 and BCL2 expression was identified in the glands and stroma of polyps when comparing overweight and obese postmenopausal patients. The present findings suggest that BMI has an influence on proliferation markers (MKI67) in the polyps of postmenopausal women and that polyps >2 cm exhibit hyperexpression of BCL2 in the stroma.

Abstract
AIM To compare the recurrence of benign endometrial polyps after office hysteroscopic polypectomy performed with a bipolar electrode (BE) or a small diameter hysteroscopic tissue removal system (HTRs). METHODS From July 2018 to December 2019 we evaluated the charts of 114 asymptomatic fertile women who underwent office hysteroscopic polypectomy, 1 year before, for a single large benign endometrial polyp (size between 10 and 20 mm) using a 4 mm continuous flow hysteroscope with a BE or a 5 mm HTRs. Patients, divided into two groups according to surgical procedure, each performed exclusively by one expert gynecologist, were scheduled for a 12-month postoperative transvaginal sonography to evaluate the recurrence of endometrial polyps. RESULTS Forty-eight women of the BE group and 42 of the HTRs group were considered for the 1-year transvaginal sonography follow-up. Five polyps were identified in the BE group and three in the HTRs group (5/48 vs 3/42, P = n.s.). All polyps were removed hysteroscopically (in three out of five and in two out of three cases, respectively, in the same places of the previous polypectomy) and evaluated as 'benign' by the pathologist. CONCLUSION Office hysteroscopic endometrial polypectomy with small HTRs compared to BE revealed at a 1-year follow-up no difference in terms of complete removal and recurrence of polyps. HTRs polypectomy resulted in less pain and significantly quicker time of procedure compared to BE. This data should be kept in mind for patient comfort any time hysteroscopic polypectomy is planned in an office setting.

Abstract
RESEARCH QUESTION Endometrial polyps are a frequent finding during fertility treatment. Although up to 27% of small polyps (<10 mm) regress spontaneously, there is clinical benefit to removing a polyp detected before intrauterine insemination (IUI), regardless of size. However, the clinical outcome of IUI following a new suspicion of a polyp during follicle tracking is unknown. DESIGN This retrospective cohort study included all patients with a normal baseline uterine ultrasound and/or hysteroscopy result who started an IUI cycle between May 2009 and March 2017. In 139 of 6606 patients (2.1%), encompassing 340 out of 15,147 cycles (2.3% of cycles), a polyp was diagnosed during the follicular phase. The 6467 controls had ultrasound results with no suspicion of a polyp. Each patient was included only once in the analysis during a maximum of three consecutive cycles of IUI. RESULTS Female age was significantly higher in the polyp group than the controls (35.4 ± 4.8 versus 33.0 ± 5.0, P < 0.01). The unadjusted cumulative live birth rate (CLBR) after three IUI cycles in women with and without a polyp was 24.1% versus 33.0% (P = 0.03), indicating a deleterious effect of polyp(s). However, after multivariate Cox regression analysis for body mass index, female age, number of follicles and sperm concentration, the presence of a polyp appeared not to influence the CLBR (adjusted hazard ratio 0.742, 95% confidence interval 0.477-1.156, P = 0.19). CONCLUSIONS These results may be reassuring, as ultrasound diagnosis of a polyp during the follicular phase of an IUI cycle does not seem to compromise clinical outcome when previous baseline examinations have been normal.

Abstract
BACKGROUND Endometrial polyps are common in postmenopausal women, and the effect of tamoxifen use (a risk factor for endometrial polyps) on their pathogenesis is unclear. OBJECTIVES To evaluate the expression of hormone receptors and markers for proliferation/apoptosis (Ki-67 and Bcl-2) in endometrial polyps in postmenopausal users and nonusers of tamoxifen. DESIGN AND SETTING Cross-sectional analytical study in a tertiary-level academic hospital. METHODS 46 women (14 tamoxifen users and 32 nonusers) with postmenopausal bleeding underwent hysteroscopic resection of endometrial polyps. Polyp samples were immunohistochemically assessed for detection of Ki-67, Bcl-2 and estrogen and progesterone receptors. RESULTS Analysis on the glandular component of the polyps revealed progesterone receptor expression in the polyps of 96.9% of the nonusers of tamoxifen, and 92.3% of the tamoxifen users (P = 0.499). All polyps in nonusers and 92.3% of those in users were also positive for estrogen receptors (P = 0.295). Ki-67 was expressed in 75% of the polyps in the tamoxifen users and 82.8% of those in the nonusers. All endometrial polyps expressed Bcl-2. CONCLUSIONS The immunohistochemical analysis on endometrial polyps demonstrated that, although tamoxifen is considered to be a risk factor for endometrial polyps, there were no significant differences in the expression of hormone receptors between users and nonusers of tamoxifen. There were no between-group differences in Ki-67 and Bcl-2 expression, and all patients displayed inhibition of apoptosis by Bcl-2, thus supporting the theory that polyps develop due to inhibition of apoptosis, and not through cell proliferation.

Abstract
Endometrial polyps are overgrowths of endometrial glands that typically protrude into the uterine cavity. Endometrial polyps are benign in nature and affect both reproductive age and postmenopausal women. Although endometrial polyps are relatively common and may be accompanied by abnormally heavy bleeding at menstruation. In asymptomatic women, endometrial polyps may regress spontaneously, in symptomatic women endometrial polyps can be treated safely and efficiently with hysteroscopic excision.

Abstract
Aim Our purpose is to investigate if transcervical resection of endometrial polyps improves the fertility in ovulatory infertile women, and whether polyp histology, intrauterine location, and the technique of polypectomy have any influence on the pregnancy rates. Methods In this retrospective study, clinical data of 87 ovulatory infertile women who underwent hysteroscopy and polypectomy, and their 12-month follow-up have been analyzed. Subgroups according to the method of polyp removal (resectoscope or curettage), the polyp localization (utero-tubal, anterior, posterior, lateral, multiple) and the histological result were interpreted. Results Mean age of patients was 33.99 ± 4.24 years. There were no differences in the BMI and basal FSH levels between the subgroups. Pregnancy was recorded in 30 (34.5%) within the next 12 months without any difference between the subgroups of polypectomy method applied. Posterior wall polyp resection increased the pregnancy chance (OR 5.02), but no other differences were observed in 1-year pregnancy rates to other localizations. Removal of polyps which had normal endometrial histology had lower pregnancy rates as compared to that of polyps with hyperplasia or endometrial polyp histology results (OR 0.25). Conclusions Polypectomy improved the conception rate in the subsequent year regardless of the intrauterine localization and the method of its surgical removal. Therefore, we can conclude that polypectomy should be considered in infertile women.

Abstract
OBJECTIVE We analyzed tamoxifen use as a malignancy risk factor in women with endometrial polyps. METHODS This retrospective study included 675 women who underwent hysteroscopic polypectomy in 2010 to 2015 at the University of Campinas. Women were divided into tamoxifen use (n = 169) and no tamoxifen use (n = 506) groups. The primary outcome was endometrial cancer prevalence. Dependent variables included age, parity, years since menopause, presence of abnormal uterine bleeding, endometrial pattern on hysteroscopy, and endometrial thickness. RESULTS There were seven cases of endometrial cancer in the tamoxifen use group (4.14%) and 41 in the no tamoxifen use group (8.1%; P = 0.083). On performing multivariate analysis, tamoxifen use was not a risk factor for endometrial cancer (prevalence ratio 0.51, 95% confidence interval [CI] 0.23-1.14, P = 0.101). The no tamoxifen use group had an increased prevalence of malignancy when women presented with abnormal uterine bleeding (prevalence ratio 3.9, 95% CI 2.08-7.29, P < 0.001), age >60 years (prevalence ratio 2.1, 95% CI 1.12-3.93, P = 0.021), or nulliparous status (prevalence ratio 3.13, 95% CI 1.55-6.35, P = 0.002). The tamoxifen use group had increased prevalence of malignancy when women were >60 years (prevalence ratio 7.85, 95% CI 1.05-58.87, P = 0.006) or nulliparous (prevalence ratio 8.36, 95% CI 2.32-30.11, P < 0.001). CONCLUSION Tamoxifen use was not related with a higher prevalence of endometrial cancer in women with endometrial polyps. Abnormal uterine bleeding, age > 60 years, and nulliparous status were associated with malignancy.

Abstract
STUDY OBJECTIVE To investigate the correlation between endometrial polyps (EPs) and chronic endometritis (CE). DESIGN Single-center retrospective case-control study. SETTING Academic center. PATIENTS A total of 480 premenopausal women with abnormal uterine bleeding (AUB) were enrolled. Group A included 240 women suffering from EPs (diagnosed by hysteroscopy and histology), and group B included 240 patients without EPs at hysteroscopy. INTERVENTIONS In group A, 2 separate samples were obtained from the EPs (group A polyps) and endometrium (group A endometrium). In group B, a single sample of endometrial tissue was evaluated (group B endometrium). All tissue samples were subjected to immunohistochemistry for CD-138 for plasma cell identification. MEASUREMENTS AND MAIN RESULTS The primary study endpoint was to compare the rates of CE in group A endometrium versus group B endometrium. The secondary endpoint was to evaluate the consistency in CD-138 immunoreactivity between group A polyps and compared with group A endometrium. A higher prevalence of CE was observed in group A endometrium compared with group B endometrium (p < .0001). The total percentage of EPs showing CD-138 positivity was 76.7% (184 of 240). CE was more frequent in women with CD-138+ EPs compared to those with CD-138- EPs (p < .0001). CONCLUSIONS EPs were commonly associated with CE in the premenopausal women suffering from AUB. Moreover, the majority of EPs were positive for CD-138 staining, suggesting a possible hidden association between chronic inflammation and EPs.

Abstract
The cost of fertility treatment is expensive and interventions that reduce cost can lead to greater efficiency and fewer embryos transferred. Endometrial polyps contribute to infertility and are frequently removed prior to infertility treatment. It is unclear whether polypectomy reduces fertility treatment cost and if so, the magnitude of cost reduction afforded by the procedure. The aim of this study was to determine whether performing office or operative hysteroscopic polypectomy prior to infertility treatment would be cost-effective. PubMed, Embase, and Cochrane libraries were used to identify publications reporting pregnancy rates after hysteroscopic polypectomy. Studies were required to have a polypectomy treatment group and control group of patients with polyps that were not resected. The charges of infertility treatments and polypectomy were obtained through infertility organizations and a private healthcare cost reporting website. These charges were applied to a decision tree model over the range of pregnancy rates observed in the representative studies to calculate an average cost per clinical or ongoing pregnancy. A sensitivity analysis was conducted to assess cost savings of polypectomy over a range of pregnancy rates and polypectomy costs. Pre-treatment office or operative hysteroscopic polypectomy ultimately saved €6658 ($7480) and €728 ($818), respectively, of the average cost per clinical pregnancy in women treated with four cycles of intrauterine insemination. Polypectomy prior to intrauterine insemination was cost-effective for clinical pregnancy rates greater than 30.2% for office polypectomy and 52.6% for operative polypectomy and for polypectomy price <€4414 ($4959). Office polypectomy or operative polypectomy saved €15,854 ($17,813) and €6644 ($7465), respectively, from the average cost per ongoing pregnancy for in vitro fertilization/intracytoplasmic sperm injection treated women and was cost-effective for ongoing pregnancy rates greater than 26.4% (office polypectomy) and 31.7% (operative polypectomy) and polypectomy price <€6376 ($7164). These findings suggested that office or operative hysteroscopic polypectomy was cost-effective when performed prior to both intrauterine insemination and in vitro fertilization over a range of plausible pregnancy rates and procedural costs.

Abstract
In the literature, there is growing evidence that assisted reproductive techniques increase the risk of pregnancy complications in subfertile couples. Moreover, many concomitant preconception risk factors for subfertility are frequently present in the same subject and increase the risk of pregnancy complications. This review aimed to summarize in a systematic fashion the best current evidence regarding the effects of preconception maternal factors on maternal and neonatal outcomes. A literature search up to March 2016 was performed in IBSS, SocINDEX, Institute for Scientific Information, PubMed, Web of Science and Google Scholar. An evidence-based hierarchy was used to determine which articles to include and analyse. Available data show that the risk of pregnancy complications in spontaneous and assisted conceptions is likely multifactorial, and the magnitude of this risk is probably very different according specific subgroups of patients. Notwithstanding the only moderate level and quality of the available evidence, available data suggest that the presence and the treatment of specific preconception cofactors of subfertility should be always taken into account both in clinical practice and for scientific purposes.

Abstract
Aims. To compare the clinical features of endometrial polyps (EPs) between patients with endometriosis (EM) (EM group) and without EM (non-EM group). Methods and Results. Seventy-six cases in the EM group and 133 cases in the non-EM group underwent laparotomy or hysteroscopy and laparoscopy; later, it was confirmed that the results by pathology from July 2002 to April 2008 in the Department of Gynecology and Obstetrics at the First Affiliated Hospital of Sun Yat-sen University. The recurrence of EPs was followed up after the surgery until 2013. The following parameters were assessed: age, gravidity, parity, infertility, and menstrual cycle changes, as well as polyps diameters, locations, number, association with the revised American Fertility Society (r-AFS) classification, and their recurrence. On review, 76 EPs cases of EM group histologically resembled EPs but the majority of EPs with EM occurred in primary infertility cases and in fewer pregnancy rate women who had stable and smaller EPs without association with the AFS stage. The recurrence rate of EPs in EM group was higher than that in non-EM group. Conclusion. It is important to identify whether infertile patients with EM are also having EPs. Removing any coexisting EPs via hysteroscopy would be clinically helpful in treating endometriosis-related infertility in these patients.

Abstract
BACKGROUND Uterine polyps cause abnormal bleeding in women and conventional practice is to remove them in hospital under general anaesthetic. Advances in technology make it possible to perform polypectomy in an outpatient setting, yet evidence of effectiveness is limited. OBJECTIVES To test the hypothesis that in women with abnormal uterine bleeding (AUB) associated with benign uterine polyp(s), outpatient polyp treatment achieved as good, or no more than 25% worse, alleviation of bleeding symptoms at 6 months compared with standard inpatient treatment. The hypothesis that response to uterine polyp treatment differed according to the pattern of AUB, menopausal status and longer-term follow-up was tested. The cost-effectiveness and acceptability of outpatient polypectomy was examined. DESIGN A multicentre, non-inferiority, randomised controlled trial, incorporating a cost-effectiveness analysis and supplemented by a parallel patient preference study. Patient acceptability was evaluated by interview in a qualitative study. SETTING Outpatient hysteroscopy clinics and inpatient gynaecology departments within UK NHS hospitals. PARTICIPANTS Women with AUB - defined as heavy menstrual bleeding (formerly known as menorrhagia) (HMB), intermenstrual bleeding or postmenopausal bleeding - and hysteroscopically diagnosed uterine polyps. INTERVENTIONS We randomly assigned 507 women, using a minimisation algorithm, to outpatient polypectomy compared with conventional inpatient polypectomy as a day case in hospital under general anaesthesia. MAIN OUTCOME MEASURES The primary outcome was successful treatment at 6 months, determined by the woman's assessment of her bleeding. Secondary outcomes included quality of life, procedure feasibility, acceptability and cost per quality-adjusted life-year (QALY) gained. RESULTS At 6 months, 73% (166/228) of women who underwent outpatient polypectomy were successfully treated compared with 80% (168/211) following inpatient polypectomy [relative risk (RR) 0.91, 95% confidence interval (CI) 0.82 to 1.02]. The lower end of the CIs showed that outpatient polypectomy was at most 18% worse, in relative terms, than inpatient treatment, within the 25% margin of non-inferiority set at the outset of the study. By 1 and 2 years the corresponding proportions were similar producing RRs close to unity. There was no evidence that the treatment effect differed according to any of the predefined subgroups when treatments by variable interaction parameters were examined. Failure to completely remove polyps was higher (19% vs. 7%; RR 2.5, 95% CI 1.5 to 4.1) with outpatient polypectomy. Procedure acceptability was reduced with outpatient compared with inpatient polyp treatment (83% vs. 92%; RR 0.90, 95% CI 0.84 to 0.97). There were no significant differences in quality of life. The incremental cost-effectiveness ratios at 6 and 12 months for inpatient treatment were £1,099,167 and £668,800 per additional QALY, respectively. CONCLUSIONS When treating women with AUB associated with uterine polyps, outpatient polypectomy was non-inferior to inpatient polypectomy at 6 and 12 months, and relatively cost-effective. However, patients need to be aware that failure to remove a polyp is more likely with outpatient polypectomy and procedure acceptability lower.

Abstract
Endometrial polyps are benign localized lesions of the endometrium, which are commonly seen in women of reproductive age. Observational studies have suggested a detrimental effect of endometrial polyps on fertility. The natural course of endometrial polyps remains unclear. Expectant management of small and asymptomatic polyps is reasonable in many cases. However, surgical resection of endometrial polyps is recommended in infertile patients prior to treatment in order to increase natural conception or assisted reproductive pregnancy rates. There is mixed evidence regarding the resection of newly diagnosed endometrial polyps during ovarian stimulation to improve the outcomes of fresh in vitro fertilization cycles. Hysteroscopy polypectomy remains the gold standard for surgical treatment. Evidence regarding the cost and efficacy of different methods for hysteroscopic resection of endometrial polyps in the office and outpatient surgical settings has begun to emerge.

Abstract
BACKGROUND Endometrial polyps, which are benign growths of the endometrium, may be a factor in female subfertility. Possible mechanisms include physical interference with gamete transport, alteration of the endometrial milieu and unresponsiveness to the cyclical global endometrial changes. As such polyps remain mostly asymptomatic, their diagnosis is often incidental during routine investigations prior to embarking on assisted reproductive treatment. Transvaginal sonography, hysterosalpingography and saline infusion sonography are the diagnostic tools most commonly employed. However, hysteroscopy remains the gold standard for diagnosis, as well as for treatment. Due to the possible effect of endometrial polyps on fertility, their removal prior to any subfertility treatment is widely practiced. OBJECTIVES To determine the effectiveness and safety of removal of endometrial polyps in subfertile women. SEARCH METHODS Electronic databases were searched, including the Cochrane Menstrual Disorders and Subfertility Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsycINFO, CINAHL and trial registers. The reference lists of identified articles were checked. The last search was performed on 30 July 2014. SELECTION CRITERIA Only randomised controlled trials, reporting pregnancy or live birth rates and complication rates as primary or secondary outcomes, in which polyps were removed surgically prior to treatment of subfertility were eligible for inclusion. The diagnosis of endometrial polyps was required to be made by transvaginal ultrasound, hysterosalpingography, saline infusion, sono-hysterography or hysteroscopy. Any surgical technique of polyp removal was acceptable, with no intervention in the control groups. DATA COLLECTION AND ANALYSIS Two review authors independently screened the titles, abstracts and full articles to assess their suitability for inclusion in this review. Quality assessment was attempted independently by two authors with discrepancies being settled by consensus or consultation with a third review author.No data extraction was performed due to the absence of useable data in the one eligible study. If there had been data to include, two review authors would have independently extracted the data from the studies using a data extraction form designed and pilot tested by the authors. Any disagreements would have been resolved by discussion or by a third review author. MAIN RESULTS Only one randomised controlled trial of endometrial polypectomy was identified for inclusion. However, a single set of data could not be extracted from this study due to internal inconsistencies of the results reported. Attempts to contact the authors to resolve the issue were unsuccessful, by phone, post and e-mail. AUTHORS' CONCLUSIONS Removal of endometrial polyps in subfertile women is commonly being performed in many countries with an aim to improve the reproductive outcome. We did not identify any analysable randomised trials which would allow us to reach any sound scientific conclusions on the efficacy of endometrial polypectomy in subfertile women. Well designed, methodologically sound, randomised controlled trials are urgently needed.

Abstract
OBJECTIVE The purpose of our study was to evaluate the relationship between endometrial polyps and obesity, diabetes mellitus (DM) and hypertension (HT). MATERIALS AND METHODS 202 patients who applied to our gynecology clinic with complaints of infertility, recurrent pregnancy loss and abnormal uterine bleeding, diagnosed to have endometrial polyps by hysteroscopy, were compared with 79 patients without polyps, retrospectively. The relationships between risk factors and presence of a polyp and polyp size were analyzed. RESULTS The mean age of cases with endometrial polyps was significantly greater than the controls. The mean body mass index (BMI) of the cases with polyps was also significantly greater than the controls. There was no significant difference between groups with respect to prevalence of DM or HT. CONCLUSION This study suggests that obesity is an independent risk factor in the development of endometrial polyps. Clinicians should be aware in terms of endometrial polyps in the assessment of patients with BMI ≥30. There was no relationship between HT or DM with presence of polyps.

Abstract
Objective: To evaluate the incidence of premalignant lesions and cancer in endometrial polyps, in patients undergoing hysteroscopic polypectomy. Methods: The results of 1,020 pathological examinations of patients submitted to hysteroscopic polypectomy were analyzed, as well as their diagnostic and surgical hysteroscopy findings. As to their menstrual status, 295 (28.9%) patients were in menacme. Of the total, 193 (65.4%) presented abnormal uterine bleeding, and 102 (34.6%) were asymptomatic with altered endometrial echo on transvaginal ultrasound. Out of 725 (71.1%) postmenopausal patients, 171 (23.6%) were symptomatic (abnormal uterine bleeding), and 554 (76.4%) were asymptomatic with endometrial echo >5.0mm. Results: Twenty-one (2.0%) patients presented premalignant lesions in the polyps, 13 had simple glandular hyperplasia, of which 5 had no atypia, and eight presented atypia. Eight polyps presented focal area of complex hyperplasia: 4 with atypia and 4 without lesions. Cancer was diagnosed in 5 (0.5%) polyps. Of the 21 polyps that harbored premalignant lesions, 12 were interpreted as benign in diagnostic and surgical hysteroscopy. Of the polyps with cancer, 4 were also histeroscopically interpreted as normal. Conclusion: Symptomatic polyps in menacme and in all postmenopausal women should be resected and submitted to histopathological examination, since they may have a benign aspect, even when harboring areas of cellular atypia or cancer.

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

Endometrial polyps in women affected by levothyroxine-treated hypothyroidism--histological features, immunohistochemical findings, and possible explanation of etiopathogenic mechanism: a pilot study. BIOMED RESEARCH INTERNATIONAL 2013; 2013:503419.

Abstract
The aim of the study was to investigate the possible overexpression of estrogen (ERs) and progesterone (PRs) receptors both in EPs glandular and stromal cells in postmenopausal women with levothyroxine-treated hypothyroidism in comparison to EPs detected in women with physiological thyroid hormone levels. During the study period (January-February 2013) 22 patients were eligible (12 treated, 10 controls). The two groups were homogenous for general, EPs sonographic and hysteroscopic features. None of the cases of atypia was found. Immunohistochemistry showed that the two groups were similar for ERs and PRs intensity rates in EPs glandular cells despite a trend of ERs percentage expression more than 60% in 2/3 of treated patients versus 1/3 of controls. In stromal EPs components, ERs intensity was high positive in 10 (83,3%) treated cases while it was high positive in 1 control (10%). Percentage of ERs stromal expression showed a different trend between the two groups despite a borderline statistical significance. Our hypothesis is based on a possible double action of hypothyroidism and thyroxine intake: the subclinical TSH increased levels and its possible circadian oscillation could stimulate the endometrial TSHRs (increasing type 2 DIO activity); the circulating levels of exogenous thyroxine could be locally metabolized in active form by type 2 DIO stimulating ERs.

Abstract
OBJECTIVE Endometrial polyp is a common cause of abnormal uterine bleeding, but the etiology and pathogenesis remain unclear. Vascular endothelial growth factor (VEGF) is angiogenic, related to thick walled vessels and transforming growth factor-beta1 (TGF-β1) is related to fibrotic tissue, which are characteristics of endometrial polyps. The primary objective of this study was to find out if endometrial polyp formation is associated with increased expression of VEGF or TGF-β1, or both. A secondary objective is to determine if the changes are related to steroid receptor expression. STUDY DESIGN This prospective study compared VEGF and TGF-β1 expression of endometrial polyps and adjacent endometrial tissue in 70 premenopausal women. The comparison of results was separately made for endometrium specimens obtained in the proliferative and secretory phases. The results were correlated with the steroid receptors (estrogen receptor and progesterone receptor) expression. RESULTS The score of VEGF in glandular cells of endometrial polyps was significantly higher than the score in adjacent endometrium, both in the proliferative phase (P<0.001) and the secretory phase (P=0.03); the score of VEGF in stromal cells of endometrial polyps was significantly higher than the score in adjacent endometrium only in proliferative phase (P=0.006). The score of TGF-β1 in glandular cells of endometrial polyps was significantly higher than the score in adjacent endometrium in proliferative phase (P=0.02); whereas the score of TGF-β1 in stromal cells of endometrial polyps was significantly higher than the score in adjacent endometrium, both in the proliferative phase (P=0.006) and the secretory phase (P=0.008). There was a significant correlation between the expression of steroid receptors and VEGF and TGF-β1 (Spearman's correlation P<0.001 and P<0.05, respectively). CONCLUSIONS There was increased expression of TGF-β1 and VEGF in polyps compared to adjacent normal endometrial tissue. It suggested that these cytokines might play a role in endometrial polyp formation. In addition, there was a significant correlation between steroid receptor expression and VEGF and TGF-β1 expression.

Abstract
OBJECTIVE To evaluate whether adenomyosis is associated with uterine polyps. STUDY DESIGN To perform an ethical human study, we planned a large retrospective observational study covering the entire patient population of the ULSS 17-Veneto district who underwent resectoscopy in 2007 and 2008 (959 patients). We enrolled all the patients underwent resectoscopy with resection of uterine polyps, with resection of myomas, with endometrial ablations by slicing, and with endometrial biopsies in both the presence and absence of hysteroscopically visible lesions. The diagnosis of adenomyosis was made by pathological examination of tissue specimens obtained using a resectoscope loop. Multivariate logistic regression was performed to determine if adenomyosis was one of the various risk factors for the presence and number of uterine polyps. Statistical Package for the Social Sciences (SPSS 16.0) was employed, and p≤0.05 was the minimum for significance. RESULTS Age (p=0.005), adenomyosis (p=0.013), high fasting glucose levels (p=0.004), and hypertension (p=0.045) were significantly associated with endometrial polyps. The presence of multiple endometrial polyps seemed to be associated with the presence of adenomyosis (p=0.016). The presence of cervical polyps was significantly associated only with presence of adenomyosis (p=0.002). The presence of multiple cervical polyps did not seem to be influenced by any of the variables considered. CONCLUSIONS The results clearly demonstrate an association between adenomyosis and uterine polyps. The pathogenetic role of adenomyosis in the development of polyps should therefore be investigated further.

Abstract
The presence of HER-2/neu (c-erbB-2) oncoprotein, oestrogen-α receptor (ER), and progesterone receptor (PR) in hyperplastic endometrial polyps (EPs) of two cats with cystic endometrial hyperplasia-pyometra (CEH-P) complex was investigated. Immunohistochemistry assay for ER, PR and c-erbB-2 oncoprotein in the glandular and stromal tissue of the EPs was performed. ER and c-erbB-2 immunoreactivity was observed in the glandular epithelium of the EPs whereas PR immunoreactivity was detected only in the stromal fibroblasts. The c-erbB-2 oncoprotein may play a role with the ER in the pathogenesis of the hyperplastic EPs, although the role of this oncoprotein in the pathogenesis of EPs has yet to be determined.

OBJECTIVES Endometrial polyps are a common cause of abnormal uterine bleeding. Rarely, a hyperplasia, either complex or atypical in type, is identified within a polyp in a biopsy or polypectomy specimen. Currently, it is not known whether the hyperplasia is likely to be confined to the polyp or also involve nonpolypoid endometrium. We aim to assess the likelihood of hyperplasia being confined to an endometrial polyp. DESIGN In this study, we identified 32 women from pathology archives in whom endometrial hyperplasia was present within a polyp. The number of endometrial polyps during the study period was 1031 and therefore 3.1% of all endometrial polyps diagnosed during the study period contained a hyperplasia. SETTING A major teaching hospital in the UK. METHODS The biopsies were retrieved from the pathology archives of Royal Group of Hospitals, Belfast, between 2000 and 2006. We traced any follow-up biopsy or hysterectomy specimens to evaluate the status of the surrounding endometrium. RESULTS The hyperplasias were complex (n = 23) or atypical (n = 9) in type. In 14 of 27 (52%) women in whom nonpolypoid endometrium was available for histological evaluation, either on the original biopsy or in a follow-up specimen, hyperplasia involved the nonpolypoid endometrium, and in three other women, hyperplasia was present in a polyp in follow-up specimens. Women with atypical hyperplasia in a polyp were slightly more likely to have hyperplasia in the surrounding endometrium than those with complex hyperplasia. CONCLUSIONS Our study illustrates that the risk of endometrial hyperplasia in a polyp concurrently involving nonpolypoid endometrium is significant. We suggest a strategy for the management of women with hyperplasia identified within an endometrial polyp in a biopsy or polypectomy specimen.

Abstract
STUDY OBJECTIVE To investigate the presence of estrogen receptors (ER) and progesterone receptors (PR) in the glandular epithelium and stroma of endometrial polyps in women who underwent hysteroscopic polypectomy. DESIGN Prospective study (Canadian Task Force classification II-3. SETTING Hospital de Servidor Público Estadual de São Paulo "Francisco Morato de Oliveira." PATIENTS Forty-eight patients with a solitary endometrial polyp who underwent hysteroscopic polypectomy and resection of an endometrial fragment. INTERVENTION The estrogen and progesterone receptor expression, in the polyp, was compared with the endometrial hormone expression of the same patients. MEASUREMENTS AND MAIN RESULTS The specimens were analyzed by immunohistochemistry. The percentage of staining cells was determined as follows: grade I, 0% to 25%; grade II, 26% to 50%; grade III, 51% to 75%; and grade IV, 76% to 100% of stained nuclei. The intensity of nuclear staining was classified as grade I, absent; grade II, weak; grade III, strong; and grade IV, very strong staining. The sum of both grades was the histochemical score. The total scores of polyp and endometrium were statistically compared. The total scores of ER of glandular epithelium were 258 in polyp and 211 in endometrium. As to stroma, it was 155 in polyp and 163 in endometrium. The total scores of PR of glandular epithelium were 286 in polyp and 211 in endometrium. As to stroma, the totals were 76 in polyp and 77 in endometrium. In immunohistochemistry, the concentrations of both ER and PR in glandular epithelium were significantly higher in endometrial polyp than in normal endometrium. The concentrations of ER and PR in the stroma were similar in the polyp and endometrium. The concentrations of these receptors in the glandular epithelium and stroma were similar in postmenopausal and premenopausal patients. CONCLUSION The concentrations of ER and PR in glandular epithelium were significantly higher in endometrial polyp than in normal endometrium. The concentrations of these receptors in the glandular epithelium and stroma were similar in the postmenopausal and pre-menopausal patients.

Abstract
OBJECTIVE To evaluate and compare the relationship of body mass index (BMI) and the immunoexpression of estrogen (ER) and progesterone receptors (PR) in endometrial polyps (EP) and endometrium, in gland and stromal cells of postmenopausal women. METHODS Thirty-five postmenopausal women with benign endometrial polyps, who had not been taking medication with hormonal effects for at least 6 months, were submitted to operative hysteroscopy. The presence of ER and PR were evaluated by immunohistochemical method using a semiquantitative analysis. RESULTS BMI was significantly higher among patients with lower expression of ER in the glands of endometrium (p=0.02). EP and adjacent endometrium showed significantly higher proportion of positive cells in the glands than in the stroma, for both ER (p=0.0015 and 0.0018, respectively) and PR (p=0.0176 and p<0.0001, respectively). Glands and stroma cells showed significantly higher proportion of positive cells in polyps than in the endometrium, for ER (p<0.0001 and p=0.0034, respectively). CONCLUSIONS The higher proportion of positive gland cells for ER in EP as compared to endometrium supports an implication of these receptors in the pathogenesis of polyps. Association of higher BMI with lower expression of ER in endometrial glands, but not in EP, may indicate that factors influencing ER expression do not affect EP, supporting an autonomous function of polyps.

Abstract
OBJECTIVE Do endometrial polyps from pre- and post-menopausal women have similar immunohistochemical expression of oestrogen and progesterone receptors (ER, PR) and markers of cellular proliferation/apoptosis (Ki67 and Bcl-2). DESIGN Prospective cohort study. Non-parametric statistical analysis was used. SETTING Polyps recruited from women attending an out-patient hysteroscopy clinic in a UK district general hospital. PATIENTS Fourteen pre-menopausal and 16 post-menopausal women who presented with abnormal bleeding with endometrial polyps. INTERVENTIONS Immunohistochemical staining was performed on endometrial polyps. MAIN OUTCOME MEASURES Significant differences or correlations between hormone receptor expression (oestrogen and progesterone) and cell growth indices (Ki67 and Bcl-2). RESULTS Endometrial polyps from pre- and post-menopausal women had significant differences in their expression of hormone receptors and Ki67. However, polyps from both groups of women had similarly increased levels of Bcl-2, an inhibitor of apoptosis. CONCLUSIONS Pre- and post-menopausal polyps exhibit differing hormone receptor and proliferation markers, presumably a result of their hormonal milieu. However, both groups appear to have lost the usual control mechanisms for apoptotic regulation, this appears to be responsible for their growth.

Abstract
Endometrial polyps represent a limited focal, circumscribed overgrowth of the endometrium. Their aetiopathogenesis has not been completely explained yet. They are often found in perimenopausal women; during the reproductive period they are less common. We present the case of a 32-year-old patient, who came for a check-up to the Gynaecology and Obstetrics Clinic "Narodni Front" because of irregular bleeding. The patient was subjected to hormonal linestrenol therapy, which she had administered herself, without further consultations with her gynaecologist, during the previous 10 years. Complete diagnostic examinations were performed. Contrast sonohysterography enabled the visualisation of multiple polyps inside the uterine cavity, which were confirmed by histopathological analysis of material obtained via explorative curettage. Histopathological material contained over 30 endometrial polyps. A control check-up after one month, as well as subsequent quarterly check-ups, resulted in normal findings. Analysis of the described case has indicated that the loss of sensitivity of progesterone receptors in endometrial cells is possible if there is a continuous presence of progesterone agonists in circulation, as is true of linestrenol in this case. The loss of sensitivity of progesterone receptors upsets normal hormonal activity during the secretory phase of the menstrual cycle, leading to copious, irregular bleeding. These changes may, however, have even deeper effects. More recent research shows that, if the agent causing the loss of sensitivity of the receptors is present in circulation over a longer time period, changes may also appear at the DNA molecular level, i.e. in the cell genome itself. This, in turn, may lead to the beginning of the process of oncogenesis and the formation of tumourous tissue.

Abstract
OBJECTIVE Our study set out to test the null hypothesis that oestrogen containing continuous combined hormone replacement therapy (HRT) would not affect the hormone receptor expression (oestrogen and progesterone receptors-ER, PR) or markers of cell proliferation/apoptosis (Ki67 and Bcl-2) in endometrial polyps from postmenopausal women exposed and not exposed to HRT. DESIGN Immunohistochemical staining for ER, PR, Ki67 and Bcl-2 was performed on polyps obtained from two groups of postmenopausal women. SETTING Polyps were obtained from postmenopausal women attending an outpatient hysteroscopy clinic in a district general hospital (Bradford Royal Infirmary, UK). POPULATION Twenty-five postmenopausal women presenting with abnormal bleeding subsequently diagnosed with endometrial polyps (16 from women not exposed to HRT, 9 from women exposed to HRT). METHODS Semiquantitative immunohistochemistry was performed. MAIN OUTCOME MEASURES Significant differences or correlations in either hormone receptor expression or markers of cell proliferation/apoptosis between the two groups of polyps. RESULTS There were no significant differences for hormone receptor expression (ER and PR) between endometrial polyps exposed and not exposed to HRT. Bcl-2 expression was higher than Ki67 in both groups, but polyps from HRT users had increased levels reflecting decreased apoptosis in these polyps. CONCLUSIONS HRT has no demonstrable effect on polyp ER and PR expression. However, HRT does appear to inhibit apoptosis and cell proliferation in endometrial polyps, which may affect polyp growth.
