Abstract
Research Question What are the growth patterns of uterine myomas in untreated premenopausal women? Which factors influence the growth rate of uterine myomas in premenopausal women? Method All premenopausal women who presented to the outpatient myoma consultation clinic between January 2005 and March 2022 at least twice were screened. Exclusion criteria were hormonal therapy, pregnancy, and postmenopausal status. Results A total of 189 patients were included in our study which focused on the respective largest uterine myoma of each woman. An ideal linear growth over time was assumed. Most myomas (82%) increased in size. The mean annual growth of these myomas was 68.42 cm 3 . The most important prognostic factor for growth was the initial size of the myoma. The absolute annual growth of myomas measuring > 50 cm 3 at first presentation was higher compared to smaller myomas (p < 0.001). The relative annual growth rate was highest for myomas measuring between 20 and 50 cm 3 at the initial presentation (p = 0.003). The relative annual growth rate in women older than 40 years was significantly lower than that in women below the age of 40 years (p = 0.003). Conclusion Overall, it is difficult to make an individual prognosis about the growth pattern of a uterine myoma in a specific patient. It should be noted especially in asymptomatic patients that spontaneous regression of myoma size can also occur in premenopausal women.

Severe chronic pelvic pain due to cystic degeneration of subserosal uterine fibroid with type 2 diabetes and obesity: Serial case report. Int J Surg Case Rep 2023; 104:107934. [PMID: 36801770 PMCID: PMC9957740 DOI: 10.1016/j.ijscr.2023.107934] [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: 11/08/2022] [Revised: 01/19/2023] [Accepted: 02/15/2023] [Indexed: 02/19/2023] Open
Abstract
INTRODUCTION AND IMPORTANCE Uterine fibroids, benign tumors of the myometrium, can cause pelvic pain. Obesity and diabetes mellitus can increase the risk of developing fibroid. We present two cases of uterine fibroid, diabetes mellitus, and obesity with moderate-to-severe chronic pain. CASE PRESENTATION The first case is a 37-year-old woman with pelvic pain and a subserosal uterine fibroid, primary infertility, grade 2 obesity, and diabetes mellitus. Pathologic examination revealed smooth muscle cells with degeneration sites. The second case is a 35-year-old nulliparous woman with abdominal enlargement, lower abdominal pain, diabetes mellitus, and morbid obesity. Ultrasonography showed a large uterus with a hyperechoic mass and cystic degeneration. Histopathological examination revealed leiomyoma. CLINICAL DISCUSSION Our patient's chronic pelvic pain may be caused by its large size. Excess adipose tissue in obesity may result in the formation of estrone, causing the proliferation of fibroids. A subserous fibroid is less likely to cause infertility; thus, a myomectomy was performed to relieve pain. Obesity and diabetes could interfere with patients' periods. Higher levels of insulin and fat tissue induce androgen production. Increased estrogen levels lead to alteration of gonadotropin production, menstrual abnormalities, and ovulatory dysfunction. CONCLUSION Cystic degeneration of the subserous uterine fibroid could induce pain though it rarely affects fertility. A myomectomy was conducted to relieve pain. Comorbid diseases such as diabetes mellitus and obesity can lead to cystic degeneration of the uterine fibroid.

Abstract
The distinguishing of uterine leiomyosarcomas (ULMS) and uterine leiomyomas (ULM) before the operation and histopathological evaluation of tissue is one of the current challenges for clinicians and researchers. Recently, a few new and innovative methods have been developed. However, researchers are trying to create different scales analyzing available parameters and to combine them with imaging methods with the aim of ULMs and ULM preoperative differentiation ULMs and ULM. Moreover, it has been observed that the technology, meaning machine learning models and artificial intelligence (AI), is entering the world of medicine, including gynecology. Therefore, we can predict the diagnosis not only through symptoms, laboratory tests or imaging methods, but also, we can base it on AI. What is the best option to differentiate ULM and ULMS preoperatively? In our review, we focus on the possible methods to diagnose uterine lesions effectively, including clinical signs and symptoms, laboratory tests, imaging methods, molecular aspects, available scales, and AI. In addition, considering costs and availability, we list the most promising methods to be implemented and investigated on a larger scale.

Abstract
Over the years, industrial accidents and military actions have led to unintentional, large-scale, high-dose human exposure to environmental contaminants with endocrine-disrupting action. These historical events, in addition to laboratory studies, suggest that exposure to toxicants such as dioxins and polychlorinated biphenyls negatively impact the reproductive system and likely influence the development of gynecologic diseases. Although high-level exposure to a single toxicant is rare, humans living in industrialized countries are continuously exposed to a complex mixture of manmade and naturally produced endocrine disruptors, including persistent organic pollutants and heavy metals. Since minorities are more likely to live in areas with known environmental contamination; herein, we conducted a literature review to identify potential associations between toxicant exposure and racial disparities in women's health. Evidence within the literature suggests that the body burden of environmental contaminants, especially in combination with inherent genetic variations, likely contributes to previously observed racial disparities in women's health conditions such as breast cancer, endometriosis, polycystic ovarian syndrome, uterine fibroids, and premature birth.

Abstract
OBJECTIVES The aim of this study was to examine the growth of uterine leiomyomas in postmenopausal women and evaluate the influencing factors associated with fibroid growth. METHODS We retrospectively analyzed the medical records of postmenopausal women with fibroids between 2015 and 2020. All women received at least 2 transvaginal ultrasound examinations within a 6-month interval. All fibroids were verified via surgery. The postoperative pathology of all tumors was uterine fibroid. We calculated the fibroid volume using the ellipsoid volume formula and evaluated the growth rate of fibroids within 6 months simultaneously. Univariable analysis and a linear mixed-effects model were used to assess the factors influencing fibroid growth. RESULTS A total of 102 postmenopausal women with a total of 132 fibroids were assessed. The median growth rate of surgically confirmed fibroids in postmenopausal women was 12.9% every 6 months (from -61.4% to 184.1%). Obesity was associated with fibroid growth (P < 0.05). Notably, the estimated growth rates of fibroids in obese and overweight women were 26.6% (95% confidence interval [CI]: 2.3-50.9) and 15.9% (95% CI: 0.4-31.4) higher than those in women of normal weight, respectively. The growth of fibroids varied by the initial tumor size (P < 0.05). The estimated growth rate of larger fibroids (≥5.0 cm diameter) was reduced 30.0% (95% CI: -52.4 to -7.5) compared with that of small fibroids (<3.0 cm diameter). CONCLUSIONS Uterine fibroids continually grow in some postmenopausal women. Obesity and small fibroids (<3.0 cm diameter) may contribute to higher growth rates of fibroids.

Abstract
OBJECTIVE To examine the association of urinary concentrations of phenols, parabens, and triclocarban with incidence and growth of uterine leiomyomata (UL; fibroids). DESIGN Case-cohort study, nested within the Study of Environment, Lifestyle, and Fibroids, a prospective cohort study. SETTING Clinic visits at baseline and every 20 months for 60 months. PATIENT(S) 754 Black women aged 23-35 years residing in the Detroit, Michigan area (enrolled during 2010-2012). INTERVENTION None. MAIN OUTCOME MEASURE(S) At each study visit, women underwent transvaginal ultrasound for measurement of UL incidence and growth and provided urine specimens in which we quantified concentrations of seven phenols, four parabens, and triclocarban. We used Cox proportional hazards regression to estimate hazard ratios and 95% confidence intervals (CIs) characterizing the relation of urinary biomarker concentrations with UL incidence during the 60 months of follow-up. In a subset of UL detected and measured at multiple time points, we used linear regression to assess the associations between biomarker concentrations and UL growth. RESULT(S) Urinary biomarker concentrations were generally inversely associated with UL incidence, but the associations were weak and nonmonotonic. For example, hazard ratios comparing concentrations ≥90th with <50th percentile were 0.77 (95% CI: 0.46, 1.27) for bisphenol A, 0.72 (95% CI: 0.40, 1.28) for bisphenol S, and 0.76 (95% CI: 0.43, 1.33) for methylparaben. Biomarker concentrations were not strongly associated with UL growth. CONCLUSION(S) In this study of reproductive-aged Black women, urinary phenols, parabens, and triclocarban biomarkers were neither strongly nor consistently associated with UL incidence and growth.

Abstract
Available evidence from IVF studies supports a detrimental effect of submucosal and intramural fibroids on embryo implantation. It is misleading, however, to infer evidence obtained in IVF settings to natural fertility. Therefore, a systematic review and meta-analysis was conducted on the effect of fibroids on natural fertility. Studies comparing fertile and infertile women, and those investigating whether the presence of fibroids was a risk factor, were reviewed, as well as studies comparing women with and without fibroids. The aim was also to establish whether the frequency of infertility differed between the two groups. Seven out of 11 selected studies did not aim to establish whether fibroids caused infertility but, rather, whether a history of infertility could be a risk factor for fibroids. A meta-analysis of the four remaining studies that concomitantly evaluated the presence of fibroids and infertility studies highlighted a common odds ratio of fibroids in subfertile women of 3.54 (95% CI 1.55 to 8.11). When focusing on the two most informative studies, i.e. the studies comparing time to pregnancy in women with and without fibroids, the common OR was 1.93 (95% CI 0.89 to 4.18). In conclusion, the association between fibroids and infertility has been insufficiently investigated. Epidemiological studies suggest, but do not demonstrate, that fibroids may interfere with natural fertility. Given the high prevalence of these lesions in women seeking pregnancy, further evidence is urgently needed.

Abstract
Uterine fibroids (UFs) are benign tumors that arise from a single genetically altered mesenchymal stem cell under the influence of gonadal hormones. UFs are the most common benign gynecologic tumors in premenopausal women worldwide. It is estimated that nearly 70% to 80% of women will develop UFs at some point during their lifetime. UFs often present with abnormal uterine bleeding (AUB), pelvic fullness, and may have deleterious effects on fertility. The natural regression of UFs begins in menopause. This is, however, a generality as this pathology may still be present in this age group. Many clinicians are concerned about hormone therapy (HT) because of UFs regrowth; nevertheless, research of this subject remains inconclusive. If UFs are present in perimenopause or menopause, they typically manifest as AUB, which represents up to 70% of all gynecological consultations in perimenopausal and postmenopausal women. As AUB is a broad symptom and may not be specific to UFs, a thorough evaluation is required for correct diagnosis and proper treatment accordingly. Understanding the unique characteristics of the available treatment modalities is crucial in deciding the appropriate treatment approach. Decision on treatment modality should be made based on selection of the least morbidity and lowest risk for each patient. Multiple modalities are available; however, surgery remains the method of choice, with the best cure rates. Various attempts to create an inexpensive, safe, and effective drug for the treatments of UFs are still in the early stages of the clinical trials with some showing great promise. Treatment options include tibolone, aromatase inhibitors, selective estrogen receptor modulators, uterine artery embolization, and selective progesterone receptor modulators.

Abstract
Uterine Fibroids (UFs), or leiomyomas, represent the most frequent pelvic tumor in reproductive-aged women. Although of benign origin, UFs decrease fertility and cause significant reproductive dysfunctions. Compared to normal myometrium, UFs are characterized by a clinical and molecular heterogeneity as demonstrated by the presence of multiple genetic alterations and altered signaling pathways. Recently, selective progesteronereceptor modulators (SPRM), as ulipristal acetate (UPA), have demonstrated their clinical benefits by reducing tumor growth and extracellular matrix deposition. For these reasons, UPA is used in the clinical practice as an intermittent treatment for women symptomatic for UFs or, sometimes, before a myomectomy. However, drug effects on signaling pathways frequently upregulated in UFs remain largely unknown. In fact, the mechanisms of action of the UPA on UFs and on the surrounding areas are not yet understood. To learn more about UPA molecular mechanisms, UF samples were treated ex vivo with UPA and profiled for drug effects on selected markers. During this preliminary ex vivo UPA administration, significant changes were observed in the expression levels of proteins related to cell cycle regulation, cytoskeleton remodeling, and drug resistance. The UPA administration reduced cofilin, Erk and Src phosphorylation, p27 and ezrin protein levels, but not Akt phosphorylation and cyclin D1 and β-catenin levels. This preliminary ex vivo biological analysis provided new insights into the mechanism of action of UPA in the treatment of UFs, which could better explain the biological functioning of the drug on UFs.

Abstract
BACKGROUND Uterine fibroids are common. Symptoms are debilitating for many, leading to high medical and societal costs. Indirect data suggest that compared with white women, African Americans develop fibroids at least 10 years earlier on average, and their higher health burden has been well documented. OBJECTIVE The objective of the study was to directly measure fibroid incidence and growth in a large, community-based cohort of young African-American women. STUDY DESIGN This observational, community-based, prospective study enrolled 1693 African-American women, aged 23-35 years with no prior diagnosis of fibroids. Standardized transvaginal ultrasound examinations at enrollment and after approximately 18 months were conducted to identify and measure fibroids ≥0.5 cm in diameter. Fibroid growth (change in natural log volume per 18 months) was analyzed with mixed-model regression (n = 344 fibroids from 251 women whose baseline ultrasound revealed already existing fibroids). RESULTS Among the 1123 fibroid-free women with follow-up data (88% were followed up), incidence was 9.4% (95% confidence interval, 7.7-11.2) and increased with age (Ptrend < .0001), from 6% (confidence interval, 3-9) for 23-25 year olds to 13% (confidence interval, 9-17) for 32-35 year olds. The chance of any new fibroid development was greater than twice as high for women with existing fibroids compared with women who were fibroid free at baseline (age-adjusted relative risk = 2.3 (confidence interval, 1.7-3.0). The uterine position of most incident fibroids (60%) was intramural corpus. Average fibroid growth was 89% per 18 months (confidence interval, 74-104%) but varied by baseline fibroid size (P < .0001). Fibroids ≥2 cm in diameter had average growth rates well under 100%. In contrast, small fibroids (<1 cm diameter) had an average growth rate of nearly 200% (188%, confidence interval, 145-238%). However, these small fibroids also had a high estimated rate of disappearance (23%). CONCLUSION This is the first study to directly measure age-specific fibroid incidence with a standardized ultrasound protocol and to measure fibroid growth in a large community-based sample. Findings indicate that very small fibroids are very dynamic in their growth, with rapid growth, but a high chance of loss. Larger fibroids grow more slowly. For example, a 2-cm fibroid is likely to take 4-5 years to double its diameter. Detailed data on fibroid incidence confirm an early onset in African-American women.

Abstract
Objective Uterine myoma which results in the magnitude of ovarian cancer remains uncertain. This study aimed to assess the association between women with previous uterine myoma and the risk of ovarian cancer. Methods This population-based case-control study was conducted using the Taiwan National Health Insurance Research Database between 2006 and 2010. We identified 4,088 adult women with newly diagnosed ovarian cancer with 16,348 women without ovarian cancer matched for age, urbanization level, income and initial diagnosis date. Logistic regression analyses were used to evaluate the variables associated with ovarian cancer. In addition, the effect of surgical interventions on the risk of ovarian cancer was also evaluated. Results Women with previous uterine myoma were more likely than those who did not to have ovarian cancer (adjusted odds ratio [aOR]=2.26; 95% confidence interval [CI]=2.06−2.49). Patients with uterine myoma who either received (aOR=1.79; 95% CI=1.51−2.13) or did not receive hormone replacement therapy (aOR=2.51; 95% CI=2.24−2.82) experienced a significantly higher risk of ovarian cancer than those without uterine myoma, respectively. However, patients with uterine myoma who underwent either myomectomy (aOR=0.55; 95% CI=0.39−0.77) or hysterectomy (aOR=0.33; 95% CI=0.26−0.42) had a significantly lower risk of ovarian cancer. Conclusion The results revealed that a significantly higher risk of ovarian cancer in women with previous uterine myoma, through an indirect mechanism. Furthermore, a lower risk of ovarian cancer was observed in women who underwent surgical removal of the uterine myoma.

Abstract
Purpose of Review This review aims to update our understanding of the radiological life cycle of fibroids, so that we may better counsel patients making difficult treatment decisions. Evidence for both pregnant and non-pregnant women have been considered separately. Recent Findings Recent findings have shown that fibroids can undergo both growth and regression in non-gravid uterus. In pregnant women, fibroid growth is non-linear fashion, with the greatest growth occurring in the first 7 weeks of pregnancy. Growth in the later trimesters was significantly slower. Summary Fibroid growth, both in the intra- and inter-gravid states, is variable and can range from 18 to 120% per year. In the inter-gravid state, fibroids can grow or undergo spontaneous regression. Factors that can predict fibroid growth include the starting volume of fibroid, type of fibroid and age of patient. In the gravid state, fibroids appears to grow in a non-linear pattern, with the most rapid growth occurring in the first trimester. Factors affecting fibroid growth in pregnancy include the size of fibroids and number of fibroids.

Abstract
OBJECTIVE To analyse fibroid vascularisation measured with three-dimensional (3D) power Doppler in relation to absolute fibroid volume change during 12 months of follow up and in relation to fibroid growth rate per year. DESIGN A prospective cohort study was performed between March 2012 and March 2014. SETTING Outpatient clinic of the VU medical centre, Amsterdam. POPULATION OR SAMPLE All premenopausal women diagnosed with a maximum of two fibroids with expectant management were consecutively included. METHODS Three-dimensional ultrasound including power Doppler was performed at baseline, 3, 6 and 12 months. Volume and vascular parameters were calculated using VOCAL software. MAIN OUTCOME MEASURES The relationship between vascular index (VI) at baseline and fibroid volume over time was analysed using linear mixed model analyses for repeated measurements. Second, the relationship between VI at baseline and fibroid growth rate per year was calculated using linear regression analyses. Analyses were adjusted for possible confounders. RESULTS In all, 66 women (mean age 42 years) completed 12 months of follow up without treatment. Baseline fibroid vascularisation (VI) measured with 3D power Doppler is correlated with fibroid volume at 12 months (P = 0.02 ). An increase of 1% in VI at baseline was associated with a 7.00-cm3 larger fibroid volume at 12 months. Furthermore, vascularisation was also associated with fibroid growth rate per year (P = 0.04). CONCLUSION In women with uterine fibroids without therapy, baseline vascularisation (VI) measured with 3D power Doppler is correlated with absolute fibroid volume change at 12 months and with fibroid growth rate per year. TWEETABLE ABSTRACT Fibroid vascularisation correlates with absolute fibroid volume change and fibroid growth rate per year.

Abstract
Previous studies have reported that uterine leiomyoma (UL) may share pathogenic features with obesity and hypertension, which are components of metabolic syndrome (MetS). We examined the association between UL and MetS in premenopausal parous women.This 1:1 case-control study was conducted on 615 asymptomatic women with UL and 615 women without UL that were matched for age, reproductive history, and hormonal use, who underwent a comprehensive health examination. UL was diagnosed by a gynecologist based on transvaginal ultrasonography findings. Blood pressure (BP), body composition, fasting plasma glucose, lipid profiles, insulin, and HOMA-IR were checked.Median age of the 1230 study subjects was 44 (40-47) years and 7% had MetS. Women with UL had significantly higher waist circumferences and body fat, BP, and low-density lipoprotein cholesterol (LDL-C) than women without UL. Although nonsignificant, the prevalence of MetS was higher in the UL group than in the non-UL group (9.3% vs 5.7%). In addition, the prevalence of UL increased as the number of abnormal metabolic components increased and was higher than in women without UL. Conditional logistic regression analysis, after adjustment for confounding factors, showed that hyperglycemia was significantly associated with an increased risk of UL (odds ratio = 1.45; 95% confidence interval, 1.10-1.89).Prevalence of abnormal metabolic component was higher in premenopausal women with UL than in normal controls, regardless of age or reproductive history. Furthermore, the study suggests that UL may share pathogenic features with the components of MetS and that women with UL be considered eligible for the early screening of metabolic abnormalities.

Abstract
A debate among gynecologic and reproductive surgeons is whether or not there is a clinical need to treat all intramural myomas. Considerations include myoma size and number, ability to access them, whether or not they compromise the endometrium, and treatment effect on gynecologic, reproductive, and obstetric outcomes. We conducted a detailed study regarding intramural myomas, their prevalence in subject populations, the imaging methods used to detect them, their growth rate, their suspected adverse effects on gynecologic, fertility, and obstetric outcomes, and the effectiveness of various treatment methods. The growing body of evidence reported in the literature supports the need to manage intramural myomas and to treat them appropriately.

Abstract
Uterine fibroids are the most common type of benign gynecologic mass, and are present in up to 80 percent of women. Research exploring risk factors for fibroids presents conflicting or inconclusive findings. Symptoms for up to 50 percent of women experiencing fibroids include heavy menstrual bleeding, pelvic pressure or pain and gastrointestinal and genitourinary changes. Diagnosis is made by history and symptoms, physical examination and imaging. Several treatment options are available, and are based on symptoms, preferences and reproductive plans. Given the high prevalence of fibroids and the potential for women's health implications, it is essential that clinicians are aware of the latest evidence regarding fibroids to provide the highest quality of care for women whose health is affected by this condition.

A single baseline ultrasound assessment of fibroid presence and size is strongly predictive of future uterine procedure: 8-year follow-up of randomly sampled premenopausal women aged 35-49 years. Hum Reprod 2015; 30:2936-44.

Abstract
STUDY QUESTION How well can a single baseline ultrasound assessment of fibroid burden (presence or absence of fibroids and size of largest, if present) predict future probability of having a major uterine procedure? SUMMARY ANSWER During an 8-year follow-up period, the risk of having a major uterine procedure was 2% for those without fibroids and increased with fibroid size for those with fibroids, reaching 47% for those with fibroids ≥ 4 cm in diameter at baseline. WHAT IS KNOWN ALREADY Uterine fibroids are a leading indication for hysterectomy. However, when fibroids are found, there are few available data to help clinicians advise patients about disease progression. STUDY DESIGN, SIZE, DURATION Women who were 35-49 years old were randomly selected from the membership of a large urban health plan; 80% of those determined to be eligible were enrolled and screened with ultrasound for fibroids ≥ 0.5 cm in diameter. African-American and white premenopausal participants who responded to at least one follow-up interview (N = 964, 85% of those eligible) constituted the study cohort. During follow-up (5822 person-years), participants self-reported any major uterine procedure (67% hysterectomies). Life-table analyses and Cox regression (with censoring for menopause) were used to estimate the risk of having a uterine procedure for women with no fibroids, small (<2 cm in diameter), medium (2-3.9 cm), and large fibroids (≥ 4 cm). Differences between African-American and white women, importance of a clinical diagnosis of fibroids prior to study enrollment, and the impact of submucosal fibroids on risk were investigated. PARTICIPANTS/MATERIALS, SETTING, METHODS There was a greater loss to follow-up for African-Americans than whites (19 versus 11%). For those with follow-up data, 64% had fibroids at baseline, 33% of whom had had a prior diagnosis. Of those with fibroids, 27% had small fibroids (<2 cm in diameter), 46% had medium (largest fibroid 2-3.9 cm in diameter), and 27% had large fibroids (largest ≥ 4 cm in diameter). Twenty-one percent had at least one submucosal fibroid. MAIN RESULTS AND THE ROLE OF CHANCE Major uterine procedures were reported by 115 women during follow-up. The estimated risk of having a procedure in any given year of follow-up for those with fibroids compared with those without fibroids increased markedly with fibroid-size category (from 4-fold, confidence interval (CI) (1.4-11.1) for the small fibroids to 10-fold, CI (4.4-24.8) for the medium fibroids, to 27-fold, CI (11.5-65.2) for the large fibroids). This influence of fibroid size on risk did not differ between African-Americans and whites (P-value for interaction = 0.88). Once fibroid size at enrollment was accounted for, having a prior diagnosis at the time of ultrasound screening was not predictive of having a procedure. Exclusion of women with a submucosal fibroid had little influence on the results. The 8-year risk of a procedure based on lifetable analyses was 2% for women with no fibroids, 8, 23, and 47%, respectively, for women who had small, medium or large fibroids at enrollment. Given the strong association of fibroid size with subsequent risk of a procedure, these findings are unlikely to be due to chance. LIMITATIONS, REASONS FOR CAUTION Despite a large sample size, the number of women having procedures during follow-up was relatively small. Thus, covariates such as BMI, which were not important in our analyses, may have associations that were too small to detect with our sample size. Another limitation is that the medical procedures were self-reported. However, we attempted to retrieve medical records when participants agreed, and 77% of the total procedures reported were verified. Our findings are likely to be generalizable to other African-American and white premenopausal women in their late 30s and 40s, but other ethnic groups have not been studied. WIDER IMPLICATIONS OF THE FINDINGS Though further studies are needed to confirm and extend the results, our findings provide an initial estimate of disease progression that will be helpful to clinicians and their patients.

Abstract
Human uterine fibroids, benign tumors derived from the smooth muscle layers of the uterus, impose a major health burden to up to 50% of premenopausal women in their daily life. To improve our understanding of this disease, we developed and characterized a patient-derived xenograft model by subcutaneous transplantation of pieces of human uterine fibroid tissue into three different strains of severe combined immunodeficient mice. Engrafted uterine fibroid tissue preserved the classical morphology with interwoven bundles of smooth muscle cells and an abundant deposition of collagenous matrix, similar to uterine fibroids in situ. The grafts expressed both estrogen receptor 1 and progesterone receptor. Additionally, both receptors were up-regulated by estrogen treatment. Growth of the fibroid grafts was dependent on 17β-estradiol and progesterone supplementation at levels similar to women with the disease and was studied for up to 60 days at maximum. Co-treatment with the antiprogestin mifepristone reduced graft growth (four independent donors, p<0.0001 two-sided t-test), as did treatment with the mTOR inhibitor rapamycin (three independent donors, p<0.0001 two-sided t-test). This in vivo animal model preserves the main histological and functional characteristics of human uterine fibroids, is amenable to intervention by pharmacological treatment, and can thus serve as an adequate model for the development of novel therapies.

Abstract
High-intensity focused ultrasound (HIFU) therapy has been used to treat uterine fibroids widely and successfully. Uterine fibroid segmentation plays an important role in positioning the target region for HIFU therapy. Presently, it is completed by physicians manually, reducing the efficiency of therapy. Thus, computer-aided segmentation of uterine fibroids benefits the improvement of therapy efficiency. Recently, most computer-aided ultrasound segmentation methods have been based on the framework of contour evolution, such as snakes and level sets. These methods can achieve good performance, although they need an initial contour that influences segmentation results. It is difficult to obtain the initial contour automatically; thus, the initial contour is always obtained manually in many segmentation methods. A split-and-merge-based uterine fibroid segmentation method, which needs no initial contour to ensure less manual intervention, is proposed in this paper. The method first splits the image into many small homogeneous regions called superpixels. A new feature representation method based on texture histogram is employed to characterize each superpixel. Next, the superpixels are merged according to their similarities, which are measured by integrating their Quadratic-Chi texture histogram distances with their space adjacency. Multi-way Ncut is used as the merging criterion, and an adaptive scheme is incorporated to decrease manual intervention further. The method is implemented using Matlab on a personal computer (PC) platform with Intel Pentium Dual-Core CPU E5700. The method is validated on forty-two ultrasound images acquired from HIFU therapy. The average running time is 9.54 s. Statistical results showed that SI reaches a value as high as 87.58%, and normHD is 5.18% on average. It has been demonstrated that the proposed method is appropriate for segmentation of uterine fibroids in HIFU pre-treatment imaging and planning.

Abstract
Fibroids are the most common tumor in women and many medical and surgical options exist for their management. The incidence of uterine sarcoma in women undergoing treatment for fibroids has previously been thought to be extremely rare, however there has been recent controversy as to whether this risk has been underestimated. This article reviews the literature investigating the incidence of leiomyosarcoma and explores how different treatment modalities may affect risk from occult malignancy. We aim to provide a tool for counseling women who are considering options for the management of their fibroids.

Abstract
Objective. Effect of isopropanolic Cimicifuga racemosa extract (iCR) on uterine fibroid size compared with tibolone. Method. The randomized, double-blind, controlled study in China enrolled 244 patients aged 40-60 years with menopausal symptoms (Kupperman Menopause Index ≥ 15). The participants were treated with either iCR of 40 mg crude drug/day (N = 122) or tibolone 2.5 mg/day (N = 122) orally for 3 months in 2004. Now, we investigated the subset of all women (N = 62) with at least one uterine fibroid at onset of treatment for the effect of iCR (N = 34) on fibroid size compared with tibolone (N = 28) by transvaginal ultrasonography. Results. The median myoma volume decreased upon iCR by as much as -30% (P = 0.016) but increased upon tibolone by +4.7%. The percentage of volume change, mean diameter change and geometric mean diameter change of the iCR group compared to tibolone were statistically significant (P = 0.016, 0.021, 0.016 respectively). Conclusion. Our results suggest that iCR (Remifemin) is a valid herbal medicinal product in patients with uterine myomas as it provides adequate relief from menopausal symptoms and inhibits growth of the myomas in contrast to tibolone.

Abstract
Background Uterine fibroids (UFs, also known as leiomyoma) affect 70% of reproductive-age women. Imposing a major burden on health-related quality-of-life (HRQL) of premenopausal women, UF is a public health concern. There are no effective medicinal treatment options currently available for women with symptomatic UF. Objectives To evaluate the efficacy and safety of green tea extract (epigallocatechin gallate [EGCG]) on UF burden and quality of life in women with symptomatic UF, in a double-blinded, placebo-controlled randomized clinical trial. Methods A total of 39 reproductive-age women (age 18–50 years, day 3 serum follicle-stimulating hormone <10 \U/mL) with symptomatic UF were recruited for this study. All subjects had at least one fibroid lesion 2 cm3 or larger, as confirmed by transvaginal ultrasonography. The subjects were randomized to oral daily treatment with either 800 mg of green tea extract (45% EGCG) or placebo (800 mg of brown rice) for 4 months, and UF volumes were measured at the end, also by transvaginal ultrasonography. The fibroid-specific symptom severity and HRQL of these UF patients were scored at each monthly visit, using the symptom severity and quality-of-life questionnaires. Student’s t-test was used to evaluate statistical significance of treatment effect between the two groups. Results Of the final 39 women recruited for the study, 33 were compliant and completed all five visits of the study. In the placebo group (n = 11), fibroid volume increased (24.3%) over the study period; however, patients randomized to green tea extract (n = 22, 800 mg/day) treatment showed significant reduction (32.6%, P = 0.0001) in total UF volume. In addition, EGCG treatment significantly reduced fibroid-specific symptom severity (32.4%, P = 0.0001) and induced significant improvement in HRQL (18.53%, P = 0.01) compared to the placebo group. Anemia also significantly improved by 0.7 g/dL (P = 0.02) in the EGCG treatment group, while average blood loss significantly decreased from 71 mL/month to 45 mL/month (P = 0.001). No adverse effects, endometrial hyperplasia, or other endometrial pathology were observed in either group. Conclusion EGCG shows promise as a safe and effective therapeutic agent for women with symptomatic UFs. Such a simple, inexpensive, and orally administered therapy can improve women’s health globally.

Abstract
OBJECTIVES To compare three-dimensional (3D) power Doppler sonographic characteristics of fibroids with histopathological parameters. METHODS We evaluated sonographically 73 fibroids before myomectomy or hysterectomy. For each, the total fibroid volume, a shell of 3 mm and a 1-cm(3) spherical sample from the most vascularized area on subjective assessment were captured. 3D power Doppler vascularization index (VI), flow index (FI) and vascularization flow index (VFI) were generated in the acquired volumes. The degree of cellularity, ischemic necrosis and fibrosclerosis, as well as CD31 and Ki-67 staining for vascular density and proliferation index, respectively, were estimated using the surgical sample. Pathological data were considered as dependent variables and ultrasound data as independent variables in multivariable logistic regression models including patients' characteristics. RESULTS A high histological 'cellular activity score', combining hypercellularity, a fibrosclerosis rate < 25% and positive Ki-67 staining, was statistically related in multivariate analyses to high 3D power Doppler VI in spherical samples (odds ratio (OR), 1.1 (95% CI, 1.0-1.3), P < 0.05) and VFI (OR, 1.3 (95% CI, 1.0-1.8), P < 0.05). Positive CD31 staining was statistically related to high 3D power Doppler VI in spherical samples (OR, 1.1 (95% CI, 1.0-1.3), P < 0.05). In contrast, ischemic necrosis was statistically related to low 3D power Doppler VI in the total volume (OR, 0.6 (95% CI, 0.4-1.0), P < 0.05) and VFI (OR, 0.4 (95% CI, 0.1-1.1), P < 0.05). CONCLUSION Vascular density, ischemic necrosis and histological cellular activity score are statistically significantly associated with some 3D power Doppler indices.

Abstract
Uterine leiomyomas, or fibroids, are the most frequent gynecological tumors in premenopausal women with as many as 65% of women becoming clinically symptomatic. Uterine fibroids are benign myometrial tumors that produce large quantities of extracellular matrix proteins. Despite its high morbidity, the molecular basis underlying the development of uterine leiomyomas is not well understood. Domestic hens of Gallus gallus domesticus develop oviductal leiomyomas similar to those found in humans. We investigated the natural history of chicken leiomyomas, in vivo expression of protein biomarkers, and in vitro expression of ovarian steroid receptors. Based on the analysis of 263 hens, tumor prevalence, tumor number per hen, and tumor size increased as the hens aged. Immunohistochemistry for alpha-smooth muscle actin (SMA) and desmin confirmed the smooth muscle phenotype of the chicken leiomyomas. Intense collagen expression was detected in these oviductal leiomyomas by Mason's trichrome, and the tumors also showed increased expression of TGFB3 and collagen type I mRNAs. Consistent with human leiomyomas, chicken fibroids displayed increased BCL2 and estrogen (E) and progesterone (P) receptor expression. Chicken leiomyomas were dissociated for in vitro culture. Cells from explants were positive for SMA, desmin, and E and P receptors until the fourth passage. These cells also displayed a response similar to human cells when challenged with halofuginone, an antifibrotic agent. Our findings indicate that the chicken is an excellent complementary model for studies involving the pathophysiology of human uterine leiomyomas.

Abstract
Submucous leiomyomas or myomas are commonly encountered by gynecologists and specialists in reproductive endocrinology and infertility with patients presenting with 1 or a combination of symptoms that include heavy menstrual bleeding, infertility, and recurrent pregnancy loss. There exists a variety of interventions that include those performed under hysteroscopic, laparoscopic and laparotomic direction; an evolving spectrum of image guided procedures, and an expanding number of pharmaceutical agents, each of which has value for the appropriately selected and counseled patient. Identification of the ideal approach requires the clinician to be intimately familiar with a given patient's history, including her desires with respect to fertility, as well as an appropriately detailed evaluation of the uterus with any one or a combination of a number of imaging techniques, including hysteroscopy. This guideline has been developed following a systematic review of the evidence, to provide guidance to the clinician caring for such patients, and to assist the clinical investigator in determining potential areas of research. Where high level evidence was lacking, but where a majority of opinion or consensus could be reached, the guideline development committee provided consensus recommendations as well.
