Abstract
Introduction: The role of p16 and p53 immunohistochemistry in the diagnosis of rare and aggressive uterine carcinosarcoma (UCS) has been well established. However, enhancer of zeste homolog 2 (EZH2), a histone methyltransferase and a member of the polycomb group family is a relatively new biomarker, with limited published data on its significance in this tumor type. The goal of this study was to examine EZH2 expression in UCS and its components, in correlation with morphological features, and p16 and p53 staining patterns. Methods: Twenty-eight UCSs were included in the study. EZH2, p16 and p53 immunoreactivity were assessed independently by two pathologists in both tumor components (epithelial and mesenchymal). EZH2 and p16 immunostains were scored semiquantitatively: based on the percentage and intensity of tumor cell staining a binary staining index ("high- or low-expressing") was calculated. The p53 staining pattern was evaluated as wild-type or aberrant (diffuse nuclear, null, or cytoplasmic expression). Statistical tests were used to evaluate the correlation between staining patterns for all three markers and the different tumor components and histotypes. Results: High EZH2 and p16 expression and aberrant p53 patterns were present in 89.3% 78.6% and 85.7% of the epithelial component and in 78.6%, 62.5% and 82.1% of the mesenchymal component, respectively. Differences among these expression rates were not found to be significant (p > 0.05). Regarding the epithelial component, aberrant p53 pattern was found to be significantly (p = 0.0474) more frequent in the serous (100%) than in endometrioid (66.6%) histotypes. Within the mesenchymal component, p53 null expression pattern occurred significantly (p = 0.0257) more frequently in heterologous sarcoma components (71.4%) compared to the homologous histotype (18.8%). Conclusion: In conclusion, EZH2, p16 and p53 seem to play a universal role in the pathogenesis of UCS; however, a distinctive pattern of p53 expression appears to exist between the serous and endometrioid carcinoma components and also between the homologous and heterologous sarcoma components.

Abstract
Women's health concerns are generally underrepresented in basic and translational research, but reproductive health in particular has been hampered by a lack of understanding of basic uterine and menstrual physiology. Menstrual health is an integral part of overall health because between menarche and menopause, most women menstruate. Yet for tens of millions of women around the world, menstruation regularly and often catastrophically disrupts their physical, mental, and social well-being. Enhancing our understanding of the underlying phenomena involved in menstruation, abnormal uterine bleeding, and other menstruation-related disorders will move us closer to the goal of personalized care. Furthermore, a deeper mechanistic understanding of menstruation-a fast, scarless healing process in healthy individuals-will likely yield insights into a myriad of other diseases involving regulation of vascular function locally and systemically. We also recognize that many women now delay pregnancy and that there is an increasing desire for fertility and uterine preservation. In September 2018, the Gynecologic Health and Disease Branch of the Eunice Kennedy Shriver National Institute of Child Health and Human Development convened a 2-day meeting, "Menstruation: Science and Society" with an aim to "identify gaps and opportunities in menstruation science and to raise awareness of the need for more research in this field." Experts in fields ranging from the evolutionary role of menstruation to basic endometrial biology (including omic analysis of the endometrium, stem cells and tissue engineering of the endometrium, endometrial microbiome, and abnormal uterine bleeding and fibroids) and translational medicine (imaging and sampling modalities, patient-focused analysis of menstrual disorders including abnormal uterine bleeding, smart technologies or applications and mobile health platforms) to societal challenges in health literacy and dissemination frameworks across different economic and cultural landscapes shared current state-of-the-art and future vision, incorporating the patient voice at the launch of the meeting. Here, we provide an enhanced meeting report with extensive up-to-date (as of submission) context, capturing the spectrum from how the basic processes of menstruation commence in response to progesterone withdrawal, through the role of tissue-resident and circulating stem and progenitor cells in monthly regeneration-and current gaps in knowledge on how dysregulation leads to abnormal uterine bleeding and other menstruation-related disorders such as adenomyosis, endometriosis, and fibroids-to the clinical challenges in diagnostics, treatment, and patient and societal education. We conclude with an overview of how the global agenda concerning menstruation, and specifically menstrual health and hygiene, are gaining momentum, ranging from increasing investment in addressing menstruation-related barriers facing girls in schools in low- to middle-income countries to the more recent "menstrual equity" and "period poverty" movements spreading across high-income countries.

Abstract
To evaluate quality of life and sexual function of childbearing-age women, affected by uterine fibromatosis undergoing medical treatment with ulipristal acetate. The data obtained by filling the questionnaires European Quality of Life Five-Dimension Scale and modified Female Sexual Function Index, were analyzed to assess UPA usefulness in improving QoL and sexual activity. A total of 139 patients affected by uterine fibromatosis undergoing conservative ulipristal acetate treatment were enrolled in this prospective observational cohort study. Seventy-one women (average age 46.5 years) answered the questionnaires: QoL and sexuality were evaluated before and after ulipristal acetate treatment. 59 patients (83.1%) had an improvement of QoL and general health state, with a reduction of VAS score after ulipristal acetate treatment. EQ-5D-5L showed a statistically significant improvement of usual act impairment, mobility, discomfort, anxiety/depression (p < .0005). There was no difference in personal care management after therapy. Modified FSFI showed a statistically significant improvement (p < .0001) of sexual satisfaction and sexual life. A not statistically significant improvement in dyspareunia was also highlighted. This study provides a clear picture about QoL impact on women and confirms the effectiveness of the ulipristal acetate in improving different aspects of daily and sexual life of patients undergoing medical treatment.

Abstract
BACKGROUND Gestational trophoblastic diseases (GTDs) are treatable rare tumors with wide distribution. The estimated incidence of GTDs varies dramatically between different regions globally. In early pregnancy, there may be high human chorionic gonadotropin (HCG) concentrations, normal or slightly increased free T4 (fT4) and subnormal thyroid-stimulating hormone (TSH), causing hyperthyroidism ranging from subclinical to severe. Beta-HCG causes thyrotoxicosis through thyroid stimulation in patients with trophoblastic tumors. OBJECTIVE To assess thyroid function among patients diagnosed with complete or partial hydatidiform mole, within the GTD spectrum. DESIGN AND SETTING Cross-sectional study based on patients' medical records at Van University Hospital, Van, Turkey. METHODS 50 patients monitored due to diagnoses of hydatidiform mole were included and were examined regarding thyroid function. Thyroid gland size and volume were measured using thyroid ultrasonography. Beta-HCG, TSH, fT4, free T3 (fT3), total T4 (TT4), total T3 (TT3), anti-thyroid peroxidase (anti-TPO), anti-thyroglobulin (anti-TG) and thyroglobulin levels were measured. RESULTS Among these patients, 15 (30%) were diagnosed with complete hydatidiform mole and 35 (70%) with partial hydatidiform mole, according to pathology results. Those with complete hydatidiform mole were older (P = 0.003), with higher number of pregnancies (P = 0.032), lower TSH level (P = 0.011) and higher fT4 and TT4 levels (P = 0.04; P = 0.028), compared with partial hydatidiform mole patients. CONCLUSION In hydatidiform mole patients, thyroid disease severity increases with age, parity, beta-HCG level and mole size. However, prospective multicenter studies on this topic are needed, with larger numbers of patients and closer monitoring.

Abstract
Endometrial polyps, adenomyosis, and leiomyomas are commonly encountered abnormalities frequently found in both fertile women and those with infertility. The clinician is frequently challenged to determine which of these entities, when found, is likely to impair fertility, and which are "innocent bystanders" unrelated to the problem at hand. Although removing an endometrial polyp may be seen as a relatively benign and safe intervention, myomectomy, and in particular adenomyomectomy, can be substantive surgical procedures, associated with their own potential for disrupting fertility. One of the mechanisms thought to be involved when these entities are contributing to infertility is an adverse impact on endometrial receptivity. Indeed polyps, adenomyosis, and leiomyomas have all been associated with an increased likelihood of abnormal endometrial molecular expressions thought to impair implantation and early embryo development. This review is designed to examine the relationship of these common entities to endometrial receptivity and to identify evidence gaps that should be considered when strategizing research initiatives. It is apparent that we have the tools necessary to fill these gaps, but it will be necessary to approach the issue in a strategic and coordinated fashion. It is likely that we will have to recognize the limitations of imaging alone and look to the evidence-based addition of molecular analysis to provide the individualized phenotyping of disease necessary for patient-specific treatment decisions.

Abstract
PURPOSE To determine the relationship between uterine leiomyoma and female sexual dysfunction (FSD) among premenopausal and postmenopausal women. MATERIALS AND METHODS The study population consisted of consecutive women who underwent gynecologic screening tests, including transvaginal ultrasound, and completed the questionnaires on FSD. A total of 841 women were included from January 2010 to December 2011. FSD was defined as Female Sexual Function Index (FSFI) ≤26.55. The relationship between uterine leiomyoma and FSD were compared according to menopausal status. RESULTS In premenopausal group (n=564), there were no differences in the frequency of FSD (55.0% vs. 58.8%, p=0.387) and total FSFI score. However, in postmenopausal group (n=277), women with uterine leiomyoma had a lower frequency of FSD than those without uterine leiomyoma (71.3% vs. 86.4%, p=0.003). This relationship between uterine leiomyoma and lower frequency of FSD in postmenopausal women remained significant after adjusting for confounding variables. CONCLUSION The relationship between uterine leiomyoma and FSD is different depending on the menopausal status.

Abstract
Objective Uterine fibroids (leiomyomas) are common benign tumors of the myometrium but their molecular pathobiology remains elusive. These stiff and often large tumors contain abundant extracellular matrix (ECM), including large amounts of collagen, and can lead to significant morbidities. After observing structural multiformities of uterine fibroids, we aimed to explore this heterogeneity by focusing on collagen and tissue stiffness. Methods For 19 fibroids, ranging in size from 3 to 11 centimeters, from eight women we documented gross appearance and evaluated collagen content by Masson trichrome staining. Collagen types were determined in additional samples by serial extraction and gel electrophoresis. Biomechanical stiffness was evaluated by rheometry. Results Fibroid slices displayed different gross morphology and some fibroids had characteristics of two or more patterns: classical whorled (n = 8); nodular (n = 9); interweaving trabecular (n = 9); other (n = 1). All examined fibroids contained at least 37% collagen. Tested samples included type I, III, and V collagen of different proportions. Fibroid stiffness was not correlated with the overall collagen content (correlation coefficient 0.22). Neither stiffness nor collagen content was correlated with fibroid size. Stiffness among fibroids ranged from 3028 to 14180 Pa (CV 36.7%; p<0.001, one-way ANOVA). Stiffness within individual fibroids was also not uniform and variability ranged from CV 1.6 to 42.9%. Conclusions The observed heterogeneity in structure, collagen content, and stiffness highlights that fibroid regions differ in architectural status. These differences might be associated with variations in local pressure, biomechanical signaling, and altered growth. We conclude the design of all fibroid studies should account for such heterogeneity because samples from different regions have different characteristics. Our understanding of fibroid pathophysiology will greatly increase through the investigation of the complexity of the chemical and biochemical signaling in fibroid development, the correlation of collagen content and mechanical properties in uterine fibroids, and the mechanical forces involved in fibroid development as affected by the various components of the ECM.

Abstract
BACKGROUND Women with symptomatic uterine fibroids can report a myriad of symptoms, including pain, bleeding, infertility, and psychosocial sequelae. Optimizing fibroid research requires the ability to enroll populations of women with image-confirmed symptomatic uterine fibroids. OBJECTIVE Our objective was to develop an electronic health record-based algorithm to identify women with symptomatic uterine fibroids for a comparative effectiveness study of medical or surgical treatments on quality-of-life measures. Using an iterative process and text-mining techniques, an effective computable phenotype algorithm, composed of demographics, and clinical and laboratory characteristics, was developed with reasonable performance. Such algorithms provide a feasible, efficient way to identify populations of women with symptomatic uterine fibroids for the conduct of large traditional or pragmatic trials and observational comparative effectiveness studies. Symptomatic uterine fibroids, due to menorrhagia, pelvic pain, bulk symptoms, or infertility, are a source of substantial morbidity for reproductive-age women. Comparing Treatment Options for Uterine Fibroids is a multisite registry study to compare the effectiveness of hormonal or surgical fibroid treatments on women's perceptions of their quality of life. Electronic health record-based algorithms are able to identify large numbers of women with fibroids, but additional work is needed to develop electronic health record algorithms that can identify women with symptomatic fibroids to optimize fibroid research. We sought to develop an efficient electronic health record-based algorithm that can identify women with symptomatic uterine fibroids in a large health care system for recruitment into large-scale observational and interventional research in fibroid management. STUDY DESIGN We developed and assessed the accuracy of 3 algorithms to identify patients with symptomatic fibroids using an iterative approach. The data source was the Carolina Data Warehouse for Health, a repository for the health system's electronic health record data. In addition to International Classification of Diseases, Ninth Revision diagnosis and procedure codes and clinical characteristics, text data-mining software was used to derive information from imaging reports to confirm the presence of uterine fibroids. Results of each algorithm were compared with expert manual review to calculate the positive predictive values for each algorithm. RESULTS Algorithm 1 was composed of the following criteria: (1) age 18-54 years; (2) either ≥1 International Classification of Diseases, Ninth Revision diagnosis codes for uterine fibroids or mention of fibroids using text-mined key words in imaging records or documents; and (3) no International Classification of Diseases, Ninth Revision or Current Procedural Terminology codes for hysterectomy and no reported history of hysterectomy. The positive predictive value was 47% (95% confidence interval 39-56%). Algorithm 2 required ≥2 International Classification of Diseases, Ninth Revision diagnosis codes for fibroids and positive text-mined key words and had a positive predictive value of 65% (95% confidence interval 50-79%). In algorithm 3, further refinements included ≥2 International Classification of Diseases, Ninth Revision diagnosis codes for fibroids on separate outpatient visit dates, the exclusion of women who had a positive pregnancy test within 3 months of their fibroid-related visit, and exclusion of incidentally detected fibroids during prenatal or emergency department visits. Algorithm 3 achieved a positive predictive value of 76% (95% confidence interval 71-81%). CONCLUSION An electronic health record-based algorithm is capable of identifying cases of symptomatic uterine fibroids with moderate positive predictive value and may be an efficient approach for large-scale study recruitment.

Abstract
Sixty-eight previously untreated female subjects were studied: 26 patients with cervical carcinoma, 22 with endometrial carcinoma, and 20 with benign uterine diseases. These patients, together with 25 healthy female control subjects, underwent several coagulation tests, including beta-thromboglobulin (beta-TG) and platelet factor 4 (PF4) plasma levels. Of all the parameters considered, the variations in beta-TG and PF4 were the most interesting. They were increased in patients with cervical and endometrial carcinoma. The sensitivity of the two tests reached 79% (15/19) for patients with invasive cervical carcinoma and 74% (16/22) for all patients with endometrial carcinoma. Our data demonstrate that among the investigated parameters beta-TG and PF4 are the earliest disorders of the hemostatic system and are more frequently increased in the gynecologic malignancies.

Abstract
The leiomyomas are a common gynecologic entity that may present unusual growth patterns or unusual locations. Its atypical presentations creates a diagnostic challenge. This is a case report of a parasitic leiomyoma located in the anterior abdominal wall in a 53 years old woman with pelvic compressive and urinary symptoms, with no history of any gynecological surgery. This case illustrates the diagnostic difficulties and describes the complementary images used in the preoperative evaluation.

Abstract
Objective To estimate the association between uterine fibroids and adverse obstetric outcomes. Methods This was a retrospective cross-sectional study of 112,403 deliveries from 14 provinces and 39 different hospitals in 2011 in mainland China. We compared pregnancy outcomes in women with and without uterine fibroids who underwent detailed second trimester obstetric ultrasonography during 18 to 22 weeks. Obstetric outcomes include cesarean delivery, breech presentation, preterm delivery, placenta previa, placental abruption, premature rupture of membranes and neonatal birthweight. Univariate analyses and multivariate logistic regression analyses were performed. Results Of 112,403 women who underwent routine obstetric survey, 3,012 (2.68%) women were identified with at least 1 fibroid. By univariate and multivariate analyses, the presence of uterine fibroids was significantly associated with cesarean delivery (Adjusted odds radio [AOR] 1.8, 95% confidence interval [CI] 1.7–2.0), breech presentation (AOR 1.3, 95% CI 1.2–1.5) and postpartum hemorrhage (AOR 1.2, 95% CI 1.1–1.4). The size of uterine fibroids and location in uterus had important effect on the mode of delivery. The rates of PPH were significantly higher with increasing size of the uterine fibroid (P<0.001). And the location of fibroid (intramural, submucosal or subserosal) also have a statistically significant impact on the risk of PPH (5.6% [subserosal] vs 4.7% [submucosal] vs 8.6% [intramural]). Conclusion Pregnant women with uterine fibroids are at increased risk for cesarean delivery, breech presentation and postpartum hemorrhage. And different characteristics of uterine fibroids affect obstetric outcomes through different ways. Such detailed information may be useful in risk-stratifying pregnant women with fibroids.

Abstract
According to the literature review, CO2 insufflation on parasitic myoma implantation is not well studied, and we concur that our study is related to "Morcellation-induced parasitic myomas." We did not compare CO2 insufflation to non-insufflation in our study. The reason is the efficacy of gasless laparoscopic myomectomy and morcellation is not well established and this modality is seldom performed. Moreover, the effects of pneumoperitoneum on mesothelial cells and the role of the entire peritoneal cavity as a cofactor in adhesion formation have become well established, the role of CO2 insufflation in the establishment of parasitic myomas has not yet been studied. As such, more in-depth and well-designed studies for the role of CO2 insufflation are needed.

Abstract
OBJECTIVES: Doppler ultrasonography can be used to assess neoangiogenesis, a characteristic feature of postmolar gestational trophoblastic neoplasia. However, there is limited information on whether uterine artery Doppler flow velocimetry parameters can predict gestational trophoblastic neoplasia following a complete hydatidiform mole. The purpose of this study was as follows: 1) to compare uterine blood flow before and after complete mole evacuation between women who developed postmolar gestational trophoblastic neoplasia and those who achieved spontaneous remission, 2) to assess the usefulness of uterine Doppler parameters as predictors of postmolar gestational trophoblastic neoplasia and to determine the best parameters and cutoff values for predicting postmolar gestational trophoblastic neoplasia. METHODS: This prospective cohort study included 246 patients with a complete mole who were treated at three different trophoblastic diseases centers between 2013 and 2014. The pulsatility index, resistivity index, and systolic/diastolic ratio were measured by Doppler flow velocimetry before and 4-6 weeks after molar evacuation. Statistical analysis was performed using Wilcoxon's test, logistic regression, and ROC analysis. RESULTS: No differences in pre- and post-evacuation Doppler measurements were observed in patients who developed postmolar gestational trophoblastic neoplasia. In those with spontaneous remission, the pulsatility index and systolic/diastolic ratio were increased after evacuation. The pre- and post-evacuation pulsatility indices were significantly lower in patients with gestational trophoblastic neoplasia (odds ratio of 13.9-30.5). A pre-evacuation pulsatility index ≤1.38 (77% sensitivity and 82% specificity) and post-evacuation pulsatility index ≤1.77 (79% sensitivity and 86% specificity) were significantly predictive of gestational trophoblastic neoplasia. CONCLUSIONS: Uterine Doppler flow velocimetry measurements, particularly pre- and post-molar evacuation pulsatility indices, can be useful for predicting postmolar gestational trophoblastic neoplasia.

Abstract
In Yucatan, Mexico, chronic exposure of Mayan population to pesticides is expected as about 30 per cent are drinking polluted water. Residues of organochlorine pesticides (OCP) were monitored in 18 municipalities of Yucatan with high mortality rates due to uterine cervix cancer. 70 blood samples collected from Mayan women living in livestock, agricultural and metropolitan area were analyzed for OCP. Solid Phase Extraction was performed on C18 cartridges and analyzed by Gas Chromatography with Electron Capture Detector. The results showed that the highest OCP levels were detected in blood of women living in the livestock area. OCP detected were endosulfan I (7.35 μg/mL), aldrin (3.69 μg/mL), 4,4' DDD (2.33 μg/mL), 1.39 and 1.46 μg/mL of δ-HCH. Women from the agricultural area had high concentrations of OCP in their blood, particularly dieldrin (1.19 μg/mL), and 1.26 μg/mL of 4,4' DDE. In the metropolitan area, 0.080 μg/mL of γ-HCH and 0.064 μg/mL of heptachlore were detected. This monitoring study was also based on epidemiological data of uterine cervical cancer. It was found that environmental factors may have facilitated the infiltration of OCP to the aquifer used for potable water supply. These factors in addition to poverty can have impacts on public health. This first exploratory study suggests that monitoring of OCP in human is important for the establishment of health promotion programs. The integrative analysis of both, environmental and social factors would be helpful to characterize the bioaccumulation of pesticides in humans.

Abstract
Epidemiological and experimental animal studies have shown that exposure to xenoestrogens during reproductive tract development reprograms target tissues, leading to increased disease risk later in adult life. To understand what defines the critical risk period for this effect, termed developmental programming, the authors assess the sensitivity of the female reproductive tract to developmental programming during various stages of neonatal development. Eker rats, which are predisposed to develop uterine leiomyoma because of a germ-line defect in the tuberous sclerosis complex 2 (Tsc-2) tumor suppressor gene, were exposed to the xenoestrogen diethylstilbestrol (DES) on either postnatal days 3 to 5, 10 to 12, or 17 to 19, 3 important periods of reproductive tract development and differentiation. Developmental programming was observed in both carrier (Tsc-2(Ek/+)) and wild-type (Tsc-2(+/+)) rats exposed to DES at days 3 to 5 and days 10 to 12 but not in rats exposed at days 17 to 19. Developmental programming resulted in increased tumor suppressor gene penetrance in Tsc-2(Ek/+) females relative to vehicle controls. In contrast, DES exposure at days 17 to 19 did not significantly increase the incidence of uterine leiomyoma in carrier females, indicating that the window of susceptibility had closed by this time. Gene expression analysis to determine what defined the susceptible (days 3-5 and days 10-12) versus resistant (days 17-19) periods revealed that in adult myometrium, expression of the estrogen-responsive genes calbindin D(9)K and progesterone receptor had been reprogrammed in females exposed to DES at days 3 to 5 and days 10 to 12 but not in those exposed at days 17 to 19. Reprogramming in response to DES exposure resulted in a hyperresponsiveness to ovarian hormones and could be prevented by ovariectomy prior to sexual maturity. Furthermore, in the neonatal uterus, DES was equally effective at inducing transcription of estrogen-responsive genes during both sensitive and resistant periods, indicating that resistance to developmental programming was not due to an inability of the estrogen receptor to transactivate gene expression. Interestingly, the resistant period coincided with the time at which reproductive tract tissues are exposed to endogenous estrogen, suggesting that target tissues are most vulnerable to developmental programming during the period in which they would normally be maintained in an estrogen-naïve state.

Abstract
In this study, the effects of high-intensity-focused ultrasound (HIFU) treatment on benign uterine tumor patients were examined. A total of 333 patients diagnosed with fibroids or adenomyosis using diagnostic sonography, treated with HIFU between February 4, 2010 and December 29, 2014 at a hospital in Korea, and followed up for three or six months were selected for this study. Their benign uterine tumor volume was measured, and the effects of HIFU treatment on the volume were analyzed according to age, disease, fertility, and treatment duration. The volume of benign tumors of the uterus changed by age in all age groups after conducting HIFU treatment for 3 and 6 months, respectively. The rate of decrease in individuals' in their twenties was the largest, at 64.9%. When the decreasing volume of benign tumors of the uterus was analyzed by type of disease, the treatment efficacy for adenomyosis was the best, with a decrease of 164.83 cm(3) after 6 months. Myoma had the fastest decreasing rate, at 68.5%. When evaluated on the basis of fertility, the volume of benign tumors of the uterus continued to decrease until 6 months after completing all procedures. The volume has continued to decrease for 6 months after all procedures. This study showed that HIFU treatments for uterine fibroid and adenomyosis is an effective non-invasive therapy via reducing the benign uterine tumor volume. Therefore, the HIFU method might replace other conventional treatment methods.

Abstract
Uterine leiomyoma (ULM), one of the most common reproductive tract neoplasms in premenopausal women, is a kind of benign tumor with multigene involved. Finding and studying the key gene involved has been a long-needed factor for developing non-surgery therapy and prevention methods. The dysregulated microRNAs were reported to play important roles in ULM pathobiology by regulating tumor growth. Our investigations have revealed that miR-197 is at low expression in ULM. Characterization of the effects of miR-197 in ULM demonstrated that downregulation of miR-197 increased cell growth and induced cell cycle arrest in the G0/G1 phase in vitro, while upregulation of miR-197 expression had the opposite effect on ULM growth and progression. Further research on the mechanism of miR-197 on the proliferation of ULM cells, we showed that miR-197 inhibited cell proliferation of ULM by directly targeting IGFBP5, which was overexpressed in ULM and played an important role in the etiology of ULM. These findings obtained in this study deliver insights and further expand our understanding of the role of miR-197 and its target IGFBP5 in ULM development, which provides a potential novel therapeutic agent to target the proliferation of ULM cells.

Abstract
We report a 72-year-old Japanese woman with severe hypoglycemia. The laboratory data, which revealed the suppression of serum insulin, suggested the existence of non-islet cell tumor hypoglycemia (NICTH). Abdominal computed tomography demonstrated the presence of a huge uterine tumor. The patient was treated with a continuous infusion of glucose, but died of sepsis on day 46. An autopsy revealed the pathological diagnosis to be a carcinosarcoma of the uterus. Interestingly, an immunohistochemical study discovered the expression of insulin-like growth factor (IGF)-II in both the carcinoma and sarcoma cells. In addition, an immunoblot analysis of blood samples revealed the presence of circulating big IGF-II. Therefore, this is a novel case of NICTH that was caused by a uterine carcinosarcoma.

Abstract
BACKROUND Uterine myomas are commonly treated with laparoscopic myomectomy or hysterectomy. Morcellation is often required to evacuate tissue through the laparoscopic incisions using a designated morcellator or through extension of a port site with self-retaining retractor and a cold scalpel. Both techniques carry a risk of inadvertently leaving tissue fragments behind. CASE We present a case of a parasitic fragment of morcellated uterus that became adherent to the small bowel, resulting in severe abdominal pain and requiring exploratory laparotomy and small bowel resection 5 months later. CONCLUSION Gynecologic surgeons should be aware of possible delayed postoperative complications that can result from parasitic myoma fragments inadvertently left behind followinig morcellation.

Abstract
OBJECTIVE To evaluate the uterus and myomatous nodules by ultrasonography and magnetic resonance imaging in different periods after uterine artery embolization (UAE). MATERIAL AND METHODS UAE was performed in 632 patients with different forms of uterine myoma. With this aim in mind, 120 cases with different forms of uterine myoma were analyzed. RESULTS Following 1, 3, 6, and 12 months, the reduction in myomatous nodules was estimated to be 18.4 and 17.3, 40.7 and 42.9, 60.4 and 61.8 and 72.5 and 74.7%, respectively (p < 0.05). Necrotic exposure of a nodule, expulsion of myomatous nodules, and removal of a partially nascent submucous nodule were observed in 18 (15%) patients. Laparoscopic myomectomy of subserous myomatous nodules was carried out in 12 (10%) cases after UAE. In doing this, interoperative blood loss was 50-80 ml. CONCLUSION UAE is an organ-sparing, highly effective uterine myoma treatment performed alone or in combination with surgery in relation to its different forms.

Abstract
UNLABELLED Background: Elevated serum levels of the epithelial marker CA125 are occasionally observed in leiomyosarcoma (LMS) patients. OBJECTIVES To assess the immunohistochemical expression of this marker in the tissue of LMS. METHODS The consecutive unselected records of all patients with LMS diagnosed during the period 1995-2012 were located and abstracted. After verification of the diagnosis, 4 μm unstained slides were prepared from each case for immunohistochemical staining for CA125. Sections of ovarian carcinoma known to express CA125 were used as positive controls. RESULTS We located 17 LMS patients from the period under study. Bleeding was the presenting symptom in 9 patients; the diagnosis was established prior to treatment in 11 patients. The tumor was in an advanced stage in 6 patients, and in 7 unstaged patients it was grossly confined to the uterus. Ten patients died within 14 months after the diagnosis. Serum CA125 levels prior to treatment were assessed in only 8 patients and were above normal limits (> 35 U/ml) in 3 of them. Two of the three with elevated serum levels were in stage III, and the third was an unstaged apparent stage I patient. None of the LMS tissue specimens demonstrated immunohistochemical expression of CA125. CONCLUSIONS CA125 was not immunohistochemically expressed in the tissue of any LMS tumors examined by us. The origin of elevated serum CA125 in some of these tumors is therefore not in its tissue and remains unknown.

Abstract
BACKGROUND Aberrant DNA methylation is a hallmark of many cancers. Classically there are two types of endometrial cancer, endometrioid adenocarcinoma (EAC), or Type I, and uterine papillary serous carcinoma (UPSC), or Type II. However, the whole genome DNA methylation changes in these two classical types of endometrial cancer is still unknown. RESULTS Here we described complete genome-wide DNA methylome maps of EAC, UPSC, and normal endometrium by applying a combined strategy of methylated DNA immunoprecipitation sequencing (MeDIP-seq) and methylation-sensitive restriction enzyme digestion sequencing (MRE-seq). We discovered distinct genome-wide DNA methylation patterns in EAC and UPSC: 27,009 and 15,676 recurrent differentially methylated regions (DMRs) were identified respectively, compared with normal endometrium. Over 80% of DMRs were in intergenic and intronic regions. The majority of these DMRs were not interrogated on the commonly used Infinium 450K array platform. Large-scale demethylation of chromosome X was detected in UPSC, accompanied by decreased XIST expression. Importantly, we discovered that the majority of the DMRs harbored promoter or enhancer functions and are specifically associated with genes related to uterine development and disease. Among these, abnormal methylation of transposable elements (TEs) may provide a novel mechanism to deregulate normal endometrium-specific enhancers derived from specific TEs. CONCLUSIONS DNA methylation changes are an important signature of endometrial cancer and regulate gene expression by affecting not only proximal promoters but also distal enhancers.

Abstract
PURPOSE We sought to quantify the proportion of uterine cancer survivors who self-report poor physical function. We then sought to quantify the association of poor physical function with physical activity (PA), walking, and lower limb lymphedema (LLL), among women with a history of uterine cancer. METHODS Physical function was quantified using the Medical Outcomes Study 12-Item Short-Form Health Survey (SF-12) questionnaire. PA, walking, and LLL were measured using self-report questionnaire. PA was calculated using metabolic equivalent hours per week (MET-h week(-1)), and walking was calculated using blocks per day (blocks day(-1)). Logistic regression estimated odds ratios (OR) and 95 % confidence intervals (95 % CI). RESULTS Among the 213 uterine cancer survivors in our survey (43 % response rate), 35 % self-reported poor physical function. Compared to participants who reported <3.0 MET-h week(-1) of PA, participants who reported ≥18.0 MET-h week(-1) of PA were less likely to have poor physical function (OR 0.03, 95 % CI 0.01-0.10; P trend < 0.0001). Compared to participants who reported <4.0 blocks day(-1) of walking, participants who reported ≥12.0 blocks day(-1) of walking were less likely to have poor physical function (OR 0.07, 95 % CI 0.03-0.19; P trend < 0.0001). Compared to participants who did not have LLL, participants with LLL were more likely to have poor physical function (OR 5.25, 95 % CI 2.41-11.41; P < 0.0001). CONCLUSION Higher levels of PA and walking associate with a lower likelihood of reporting poor physical function. The presence of LLL associates with a higher likelihood of reporting poor physical function. These findings are hypothesis-generating and should be evaluated in future prospective studies.

Abstract
INTRODUCTION The effect of a hyperthyroid or euthyroid state on liver function tests in patients with hydatidiform moles (HM) is not known. The aim of this study was to determine the effect of hyperthyroidism on liver transaminases in HM. PATIENTS AND METHODS We retrospectively reviewed aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in 80 patients with HM (23 complete moles and 57 partial moles). RESULTS Of the 80 HM patients, 52 (65%) were euthyroid and 28 (35%) were hyperthyroid. The number of gravida and the levels of serum β-human chorionic gonadotropin (β-HCG), AST, and ALT were significantly higher in the hyperthyroid state than in the euthyroid state (p = 0.033, p = 0.001, p = 0.001 and p = 0.001; respectively). Number of gravida, serum TSH and total T4 were significantly higher in complete HM than partial HM (p < 0.05, p < 0.001, p < 0.05; respectively). CONCLUSIONS Our results demonstrated that HM-related β-HCG may activate thyroid cells via TSH-related signalling, resulting in the release of high levels of FT4, FT3, TT3 and TT4, and a subsequent decrease in TSH.

Abstract
This article presents the theoretical background of an azimuthally stable method of Jones-matrix mapping of histological sections of a uterine wall biopsy on the basis of spatial-frequency selection of the mechanisms of linear and circular birefringence. The diagnostic application of a new correlation parameter--a complex degree of mutual anisotropy--is analytically substantiated. The method of measuring coordinate distributions of a complex degree of mutual anisotropy with further spatial filtration of their high- and low-frequency components is developed. The interconnections of such distributions with linear and circular birefringence parameters of the uterine-wall-endometrium histological sections are found. The comparative results of measuring the coordinate distributions of a complex degree of mutual anisotropy formed by fibrillar networks of myosin and collagen fibrils of uterus wall tissue of different pathological states--pre-cancer (dysplasia) and cancer (adenocarcinoma)--are shown. The values and ranges of change of the statistical (moments of the first to fourth orders) parameters of complex degree of mutual-anisotropy coordinate distributions are studied. The objective criteria of diagnosing the pathology and differentiation of its severity degree are determined.

Abstract
The myoma pseudocapsule (MP) is a fibro-vascular network rich of neurotransmitters, as a neurovascular bundle, surrounding fibroid and separating myoma from myometrium. We investigated the distribution of the opioid neuropeptides, as enkephalin (ENK) and oxytocin (OXT), in the nerve fibers within MP and their possible influence in human reproduction in 57 women. An histological and immunofluorescent staining of OXT and ENK was performed on nerve fibers of MP samples from the fundus, corpus and isthmian-cervical regions, with a successive morphometric quantification of OXT and ENK. None of the nerve fibers in the uterine fundus and corpus MPs contained ENK and the nerve fibers in the isthmian-cervical region demonstrated an ENK value of up to 94 ± 0.7 CU. A comparatively lower number of OXT-positive nerve fibers were found in the fundal MP (6.3 ± 0.8 CU). OXT-positive nerve fibers with OXT were marginally increased in corporal MP (15.0 ± 1.4 CU) and were substantially higher in the isthmian-cervical region MP (72.1 ± 5.1 CU) (p < 0.01). The distribution of OXY neurofibers showed a slight into the uterine corpus, while are highly present into the cervico-isthmic area, with influence on reproductive system and sexual disorders manifesting after surgical procedures on the cervix.

Abstract
Many studies have focused on cyclooxygenase-2 (COX-2) alterations as a critical step in the onset and progression of cancer. Moreover, a strong correlation between COX-2 and chemoresistance has been demonstrated in several carcinomas. Recently, COX-2 expression has been observed in uterine carcinosarcoma, osteosarcoma, and rhabdomyosarcoma. We investigated COX-2 expression in chemoresistant uterine leiomyosarcoma in 30 patients who had undergone surgical treatment. COX-2 expression was observed in 13 cases (43.3%). Of the 13 patients with distinct COX-2 positive immunoreactivity uterine leiomyosarcomas, 7 had stage I or II disease and 6 had stage III or IV disease. The expression of COX-2 in uterine stromal malignancies may reveal a therapeutic hypothesis in the context of uterine leiomyosarcoma molecular chemotherapeutic approach.

Abstract
CONTEXT Uterine leiomyoma, the most common tumors found in the women of the reproductive age, may cause abnormal uterine bleeding and be life threatening. Compared with myometrium, leiomyoma contains excessive extracellular matrix (ECM). However, the pathological roles of ECM in the development of leiomyoma remain largely unknown. Integrins are the major adhesion molecules on cell surface to interact with ECM. The interactions of ECM with integrins regulate cell adhesion and initiate signals for cell growth, differentiation, and migration. OBJECTIVE The aim of this study was to investigate the expression and functional role of integrin-β1 in leiomyoma pathogenesis. DESIGN Levels of integrin-β1 protein were determined by Western blotting in paired normal and leiomyomal tissues (n = 15). Knockdown of integrin-β1 and inhibition of ECM-integrin interaction by disintegrin were used to evaluate the impact of integrin-β1 in cell adhesion, spreading, and proliferation. RESULTS Levels of integrin-β1 were significantly up-regulated in leiomyomal cells compared with their normal counterparts. Knockdown of integrin-β1 did not affect cell adhesion on fibronectin or laminin matrix but significantly inhibits cell spreading ability. Consistent with this notion, the phosphorylation of focal adhesion kinase and the recruitment of paxillin to the focal contact were decreased in integrin-β1 knockdown cells, which attenuates contraction force. The inability of cell spreading leads to inhibition of cyclin D1 expression and impedes cell cycle progression. More importantly, disruption of ECM-integrin interaction by the small protein, disintegrin inhibited cyclin D1 expression and cell proliferation. CONCLUSION These data demonstrate that integrin-β1 is a critical ligand to enhance cell-ECM contact force and thus promotes cell proliferation. Disruption of ECM-integrin-β1 signaling may serve as an option to inhibit the progression of leiomyoma.

Abstract
The uterine myoma pseudocapsule is a neurovascular bundle surrounding fibroid, containing neuropeptides, probably involved in uterine scar healing. We studied neurotensin (NT), neuropeptide tyrosine (NPY), and protein gene product 9.5 (PGP 9.5) nerve fibres in the pseudocapsule neurovascular bundle of intramural uterine fibroids on 67 no pregnant women by intracapsular myomectomy sparing the neurovascular bundle, sampling full thickness specimens of the pseudocapsule of uterine fibroids (PUF) and normal myometrium (NM) obtained from the fundus uteri (FU) and the uterine body (UB). The samples were sent for histological and immunofluorescent analyses and compared by morphometrical quantification. The Conventional Unit (C.U.) difference of NT, NPY, and PGP 9.5 nerve fibres was statistically analyzed. Our results showed that NT, NPY, and PGP 9.5 neurofibers are almost equally present in PUF as in NM of a no pregnant uterus. As all of these neuropeptides are present in the uterine muscle and can affect muscle contractility, uterine peristalsis and muscular healing. A myomectomy respecting the pseudocapsule neurofibers should facilitate smooth muscle scarring and promote restoration of normal uterine peristalsis with a possible positive influence on fertility.

Abstract
Introduction Uterine cancer was the most rapidly increasing malignancy and the second most common gynecologic malignancy in Taiwan. Methods We analyzed the secular trend of uterine cancer incidence and compare the survival of women with uterine carcinomas and uterine sarcomas in Taiwan. Data on women diagnosed with uterine cancer between 1979 and 2008 were obtained from the Taiwan cancer registry. Survival data were analyzed by using Kaplan-Meier and Cox proportional hazards regression methods. Results Records of 11,558 women with uterine carcinomas and 1,226 women with uterine sarcomas were analyzed. The age-adjusted incidence rate of endometrioid adenocarcinoma increased from 0.83 per 100,000 women per year between 1979 and 1983 to 7.50 per 100,000 women per year between 2004 and 2008. The 5-year survival rate of women with endometrioid adenocarcinoma (83.2%) was higher than that for women with clear cell carcinoma (58.3%), serous carcinoma (54.4%), and carcinosarcoma (35.2%) (p<0.0001, log-rank test). The 5-year survival rates of women with low grade endometrial stromal sarcoma, endometrial stromal sarcoma, leiomyosarcoma (LMS), and adenosarcoma were 97.5%, 73.5%, 60.1%, and 77.2%, respectively (p<0.0001, log rank test). The histologic type of endometrioid adenocarcinoma, young age, and treatment period after 2000 were independent, favorable prognostic factors in women with uterine carcinomas by multivariate analysis. The histologic type of LMS, old age, and treatment period after 2000 were independent, poor prognostic factors in women with uterine sarcomas by multivariate analysis. Conclusions An increase over time in the number of patients with endometrioid adenocarcinomas was noted in this 30-year, nationwide, population-based study. Histologic type, age and treatment period were survival factors for uterine cancers. A more comprehensive assessment of uterine cancers and patient care should be undertaken on this increasingly common type of cancer.

Abstract
Adenomyosis is largely under diagnosed before hysterectomy and commonly co-exists with uterine fibroid. Thus this study aimed to elicit the clinical profile of adenomyosis by comparison with uterine fibroid. This is a hospital based prospective case-control study carried out from 1st April 2010 to 31st May 2011 which comprise of women undergoing hysterectomy with a histological diagnosis of sole adenomyosis without fibroid, women with both adenomyosis and fibroid and women with fibroid but no adenomyosis. Ambulatory records were performed. The study comprised 150 women, 78 (52%) women with adenomyosis without fibroid, 27 (18%) women with both adenomyosis and fibroid, 45 (30%) women with fibroid but no adenomyosis. Among women with adenomyosis alone, 78.2% had menorrhagia, 73.1% had dysmenorrhoea, 76.9% had chronic pelvic pain and women with adenomyosis and fibroid had menorrhagia in 85.2%, dysmenorrhoea in 51.9%, chronic pelvic pain in 48.1% compared with women of fibroid alone had menorrhagia in 75.6%, dysmenorrhoea in 66.77%, chronic pelvic pain in 51.1%. Women with adenomyosis group had significantly more of chronic pelvic pain (p-value: 0.003) and had significantly greater parity (p-value: 0.002). Size of uterus was significantly smaller in adenomyosis group (p-value: 0.018) as well as significantly more tender uterus was found in adenomyosis group (p-value: 0.000). Adenomyosis is more frequent among women reporting dysmenorrhoea, menometrorrhagia, chronic pelvic pain and along with bulky uterus. Women with fibroid alone has more of menorrhagia than pain and is associated with enlarge uterus. If women have small fibroid uterus but have more symptoms--think about co-existence of "ADENOMYOSIS".

Abstract
We propose that stem cells that display specific phenotypic and functional characteristics exist in human uterine myometrium. Under hypoxic circumstances, estrogen signaling pathways in certain myometrial stem cells are aberrantly activated, which leads to continuous differentiation of this portion of cells into leiomyoma cells. This process also protects the cells from undergoing physiological apoptotic or dedifferentiation. Therefore, we summarized some evidences for our bases and hypothesize that hypoxia may be the key contributor to the pathogenesis of leiomyoma through aberrant estrogen pathway activation of myometrial stem cells.

Abstract
OBJECTIVE To evaluate the quality of life (QOL) of patients who were diagnosed with gestational trophoblastic neoplasia (GTN) at the Philippine General Hospital Trophoblastic Disease Section and who were in remission at the time of this study. STUDY DESIGN A cross-sectional descriptive study designed to measure the QOL of all patients diagnosed as having GTN in remission and following up at the Philippine General Hospital Trophoblastic Disease Outpatient Clinic from May-August 2008 (N = 46). This study used the short form 12-question (SF-12) survey forms to evaluate the QOL of patients diagnosed with GTN. Scores from the SF-12 were analyzed using Pearson's correlation. Statistical significance was assumed for p values < 0.05 and 0.01 for all statistical tests. RESULTS Forty-six GTN survivors included in the study successfully answered all the questions. Using Pearson's correlation of demographic characteristic variables and SF-12 domains, it was found that there was better physical functioning among younger patients, and there was mild limitation in moderate activities during a typical day among older patients. There was a significant positive correlation between educational level and physical functioning. A negative correlation was found between the stage of GTN and patients' general health. In conclusion, the survivors' age, educational level and type of treatment had impact on the QOL among GTN survivors in terms of physical functioning. No relationship was established between the demographic variables and mental status. CONCLUSION SF-12 appears to be a reliable instrument, suggesting its potential in measuring health status in GTN survivors. Age, educational attainment and type of treatment were shown to have an impact on the QOL of the surviving GTN patients.

Abstract
OBJECTIVE To evaluate the role of senescence in symptomatic patients with multifibroids. DESIGN A cohort study. SETTING University research laboratory. PATIENT(S) Eighty-six fibroids collected from 14 patients who underwent myomectomy or hysterectomy. INTERVENTION(S) Senescence-associated beta-galactosidase (SA-beta-Gal) stain in fresh-frozen tissue; reverse-transcription polymerase chain reaction (RT-PCR); MicroRNA in situ hybridization (MISH); immunohistochemistry in formalin-fixed paraffin-embedded tissue. MAIN OUTCOME MEASURE(S) Senescence measured by percentage of SA-beta-Gal-positive cells; levels of let-7 microRNAs measured by RT-PCR and MISH; expression of p16(INK4a), Ki-67, HMGA1, and HMGA2 scaled by immunoreactivity. RESULT(S) About 58% (48 of 82) of tumors showed significant senescent change (SA-beta-Gal positive) in >10% of the tumor volume. The overall trend was a higher level of senescence in small fibroids and older-aged women. Senescent fibroids were additionally shown to have, high levels of let-7 c, d, and f-2 and a low Ki-67 index. CONCLUSION(S) Senescence is a common cellular change in a large proportion of usual type fibroids. Similarly, senescence may explain the variation in growth rates of these tumors, and may prove to be an important molecular and cellular target in prevention of fibroid growth.

Abstract
Cancer disease is associated with a lot of very burdening symptoms. Pain is with dyspnea and emesis in the first time in a rate of about 50%, in the terminal stage up to 90% the most tormenting symptom. For more than 90% of patients the 3-step-WHO-regimen for cancer pain is able to relieve pain successfully. But a little group of cancer patients need invasive measures and methods to relieve pain sufficiently. This would be the 4th step, according to the enlarged WHO-regimen. Intravenous or intrathecal applications, eventually regional blockades should be considered. The following case-report shows the steps of a difficult cancer pain therapy in a regional general hospital. It is sometimes not evidence based, on the one hand because of necessary organizational, staff-related, or other makeshifts in daily clinical practice, on the other hand because of the lack of appropriate EBM-guidelines. The pressure to reduce the pain effectively and as simple as possible produces sometimes polypragmatic, retrospective not always satisfying measures.

Abstract
OBJECTIVE To study whether dysregulation of insulin-like growth factors (IGFs) and IGF signaling are common molecular changes in symptomatic leiomyomas (fibroids) and whether IGFs are associated with large fibroids. DESIGN Examination of IGFs and IGF pathway genes in a large cohort of fibroids at transcriptional and translational levels. Mechanisms leading to alterations of IGFs and related genes were also analyzed. SETTING University clinical research laboratory. PATIENT(S) Hysterectomies for symptomatic fibroids were collected: 180 cases from paraffin-embedded tissues and 50 cases from fresh-frozen tissues. INTERVENTION(S) Tissue microarray and immunohistochemistry, DNA methylation analysis, reverse-transcriptase polymerase chain reaction, and Western blot. MAIN OUTCOME MEASUREMENT(S) Transcription and translation analyses of IGF-1/2, p-AKT, p-S6K, and TSC1/2 in fibroids and matched myometrium. RESULT(S) Insulin-like growth factors and downstream effectors were dysregulated in approximately one third of fibroids. All except for IGF-2 seemed to be abnormally regulated at translation levels. Up-regulation of IGF-2 messenger RNAs was contributed by all four alternating slicing promoters. There was a positive correlation of IGF-1 and p-AKT over-expression with fibroid size. Insulin-like growth factor 1 but not IGF-2 levels directly correlated with activation of p-AKT and p-S6K. CONCLUSION(S) Altered expressions of IGFs and their related downstream proteins were found in one third of fibroids. Large fibroids show high levels of IGF-1 and p-AKT activity compared with small ones.

Abstract
OBJECTIVE To examine the coexistence of fibroids and ultrasonically diagnosed polycystic ovaries (PCO) and their combined effects on the uterine artery blood flow in relation to age and parity in women with regular menstruation. STUDY DESIGN One thousand seventy women, 18-40 years old, with gynecologic or infertility problems, were investigated with transvaginal ultrasound for uterine fibroids and PCO. A subgroup of 468 patients with regular cycles had repeated examinations up to ovulation time. Midcycle mean uterine artery pulsatility index (PI) and Doppler pulse waveform patterns were examined in relation to age, parity, PCO and fibroids. Cross tabulation with chi2 and ANOVA were used for data analysis. A two-tailed p value < 0.05 was taken as significant. RESULTS One hundred eleven of 343 patients > 35 years old (32.4%) had PCO compared to 479/727 younger women (65.9%) (p < 0.001). Furthermore, fewer patients with PCO (67 of 590, 11.4%) had fibroids as compared to patients with normal ovaries (131 of 480, 27.3%) (p < 0.001). This negative correlation was maintained irrespective of age, parity or ethnic origin. PCO were associated with higher uterine artery PI and more unfavourable Doppler pulse waveform patterns in women < 35 years old and nulliparous women. This effect was not maintained in parous women and those > or = 35 years old. Fibroids did not alter the effect of PCO but increased the uterine artery blood flow in patients with normal-looking ovaries. CONCLUSION The effect of PCO on the uterine artery blood flow is modulated by age and parity but not by fibroids, which are less common in women with PCO.

Abstract
The extracellular matrix (ECM) has been thought to contribute to the pathogenesis of uterine leiomyomas. Uterine leiomyomas have abundant ECM components, including collagen, fibronectin, and glycosaminoglycans. Recent studies have demonstrated the overexpression of versican in uterine leiomyomas. Versican is a chondroitin sulfate proteoglycan that constitutes the main component of the ECM. However, the role of versican in the growth of uterine leiomyomas remains unknown. In this article a putative role of versican in uterine leiomyomas is discussed in association with cell proliferation and apoptosis..

Abstract
CONTEXT Uterine leiomyomas are the most frequent benign tumors during reproductive age. Whether intramural leiomyomas cause infertility and should be removed is controversial because no study has addressed the underlying mechanism of infertility. OBJECTIVE The objective of the study was to test the effect of intramural leiomyomas on endometrial function by comparing gene during the window of implantation and implantation in an oocyte donation program, in which the quality of the embryos replaced is similar and the endocrine environment of the endometrium is standardized by exogenous steroids. DESIGN Human endometria of women with single intramural leiomyomas (group A, <5 cm and group B, > or =5 cm) and controls (group C) were collected on day LH+7 and processed for histology and gene expression analysis, using different methods and validated by quantitative RT-PCR. To compare in vitro fertilization outcome, a total of 1035 cases from our oocyte donation database were included, comprising patients with one fibroid less than 5 cm (A1, n = 532); two leiomyomas less than 5 cm (A2, n = 128); three or more leiomyomas less than 5 cm (A3, n = 125); one fibroid 5 cm or greater (B, n = 22); and two control groups: C1 (n = 93), women with previous myomectomy; and C2 (n = 135), women without uterine pathology treated on the same dates as C1. RESULTS There was a strong positive and negative correlation in the expression profile of 69 genes according to the leiomyomas's size, but only three of the 25 genes related to the window of implantation were dysregulated. Term pregnancy rates after oocyte donation were 36.9, 34.1, 39.0, 36.4, 39.2, and 42.6% (P = 0.769) among the established groups. Similarly, no correlation between implantation and miscarriage with leiomyoma number and size was found. CONCLUSIONS This study provides evidence that intramural leiomyomas not affecting the endometrial cavity alters the expression pattern of some endometrial genes, but the genes involved in implantation are not affected. This is confirmed by leiomyomas having no effect on oocyte donation outcome when the size and number of leiomyomas are analyzed.
