The impact of uterine leiomyomas: a national survey of affected women

Development of a brief menstrual quality of life measure for women with heavy menstrual bleeding

BACKGROUND

The National Institute for Health and Care Excellence advises that considerations around quality of life should be made when assessing and treating heavy menstrual bleeding. A quick and reliable method for women to assess the impact of HMB on their quality of life might encourage help-seeking. This research aimed to develop a new 10-item measure of menstrual quality of life (the PERIOD-QOL).

METHODS

Three pilot studies describe PERIOD-QOL development and a cross-sectional survey (N = 376) assessed PERIOD-QOL scores in women who reported HMB and those who did not. A population sample of women (mean age 30.29, SD = 9.06) completed the PERIOD-QOL and rated their menstrual bleeding as heavy/very heavy/extremely heavy (HMB group) or very light/light/moderate bleeding (LMMB) group. Data were analysed using independent samples Analysis of Variance and independent samples t-tests.

RESULTS

Cronbach's Alpha for the PERIOD-QOL = .88. A significant reduction in PERIOD-QOL scores was found across the 6 levels of bleeding from very light to extremely heavy, and significantly lower PERIOD-QOL scores were reported in the HMB than the LMMB group.

CONCLUSION

The results suggest that the PERIOD-QOL is a reliable measure and that women experiencing HMB reported significantly lower menstrual quality of life than those who did not. Further validation of the PERIOD-QOL is required to determine its relationships with existing measures of menstrual quality of life and to establish whether PERIOD-QOL scores are associated with decisions to seek help from health professionals and with verified diagnoses of conditions that cause HMB.

Reproductive and Obstetric Outcomes after UAE, HIFU, and TFA of Uterine Fibroids: Systematic Review and Meta-Analysis

Novel treatment options for uterine fibroids, such as uterine artery embolization (UAE), ultrasound-guided and magnetic resonance-guided high-intensity focused ultrasound (USgHIFU and MRgHIFU), and transcervical radiofrequency ablation (TFA) methods, are widely used in clinical practice. This systematic review and meta-analysis (CRD42022297312) aims to assess and compare reproductive and obstetric outcomes in women who underwent these minimally invasive approaches for uterine fibroids. The search was performed in PubMed, Google Scholar, ScienceDirect, Cochrane Library, Scopus, Web of Science and Embase. Risk of bias was assessed using the Newcastle-Ottawa Scale (NOS) and Cochrane guidelines. The articles were selected to meet the following eligibility criteria: (1) research article, (2) human subject research, and (3) the study of pregnancy outcomes after the treatment of uterine fibroids by either one of three methods-UAE, HIFU, and TFA. The analysis of 25 eligible original articles shows a similar rate of live births for UAE, USgHIFU, MRgHIFU, and TFA (70.8%, 73.5%, 70%, and 75%, respectively). The number of pregnancies varied considerably among these studies, as well as the mean age of pregnant women. However, the results of pregnancy outcomes for TFA are insufficient to draw firm conclusions, since only 24 women became pregnant in these studies, resulting in three live births. The miscarriage rate was highest in the UAE group (19.2%). USgHIFU was associated with a higher rate of placental abnormalities compared to UAE (2.8% vs. 1.6%). The pooled estimate of pregnancies was 17.31% to 44.52% after UAE, 18.69% to 78.53% after HIFU, and 2.09% to 7.63% after TFA. The available evidence confirmed that these minimally invasive uterine-sparing treatment options for uterine fibroids are a good approach for patients wishing to preserve their fertility, with comparable reproductive and obstetric outcomes among the different techniques.

Use of oral GnRH antagonists combined therapy in the management of symptomatic uterine fibroids

Uterine fibroids have an impact on women’s lives due to their high prevalence, physical symptoms, their consequences on patients’ emotional and psychological well-being and loss of work productivity. The choice of therapeutical approaches varies depending on several factors, and therefore should be applied individually. Currently, there is an unmet need for good, reliable, uterine-sparing options. The oral GnRH antagonists (Elagolix, Relugolix, Linzagolix) represent a new alternative for the medical management of hormone-dependent gynaecological diseases such as uterine fibroids or endometriosis. They rapidly bind to the GnRH receptor, block endogenous GnRH activity and directly suppress LH and FSH production, avoiding unwanted flare-up effects. Some GnRH antagonists are marketed in combination with hormone replacement therapy add-back to counteract hypo-oestrogenic side effects. According to the registration trials, once-daily GhRH antagonist combination therapy results in a significant reduction in menstrual bleeding, as compared with placebo, and preserves bone mineral density, for up to 104 weeks. Further studies in the long term are needed to evaluate the whole impact of medical treatment of uterine fibroids on the management of this common women’s disease.

Quality of life with relugolix combination therapy for uterine fibroids: LIBERTY randomized trials

BACKGROUND

Symptomatic uterine fibroids are burdensome to live with; they are associated with symptom-related distress, affect daily activities, and reduce health-related quality of life. The LIBERTY randomized clinical trials showed that oral relugolix combination therapy (40 mg relugolix, 1 mg estradiol, and 0.5 mg norethindrone acetate once daily) markedly improved fibroid-associated symptoms and conditions, including heavy menstrual bleeding, pain, and anemia, and was well-tolerated.

OBJECTIVE

This study aimed to evaluate the effect of relugolix combination therapy on the symptom burden and health-related quality of life among women with uterine fibroids.

STUDY DESIGN

Two replicate, multinational, double-blind, 24-week, randomized, placebo-controlled, phase 3 studies, LIBERTY 1 and LIBERTY 2, were conducted in premenopausal women with uterine fibroid-associated heavy menstrual bleeding (≥80 mL per cycle for 2 cycles or ≥160 mL during 1 cycle). The symptom burden and health-related quality of life were secondary endpoints and were assessed using the validated Uterine Fibroid Symptom and Quality of Life questionnaire, which the participants completed at baseline and at week 12 and 24 of treatment. For this secondary analysis, the pooled LIBERTY 1 and LIBERTY 2 data set was used. The Uterine Fibroid Symptom and Quality of Life questionnaire is made up of a Symptom Severity scale and a Health-Related Quality of Life scale, the latter of which includes 6 subscales focusing on the following aspects of daily life: concern, activities, energy or mood, control, self-consciousness, and sexual function. The Revised Activities subscale of the Health-Related Quality of Life scale addresses the impact of uterine fibroids on physical and social activities. Symptom burden was also assessed via the Bleeding and Pelvic Discomfort subscale, a patient-reported outcome measure derived from the Uterine Fibroid Symptom Severity scale that focuses on distress from key uterine fibroid symptoms, which was a key secondary endpoint. Least squares mean changes from baseline to week 24 in the Symptom Severity scale, Bleeding and Pelvic Discomfort subscale, overall Health-Related Quality of Life scale, and the respective subscales were compared between the relugolix combination therapy and placebo groups. Responder analyses of the proportion of women who experienced a clinically meaningful change from baseline to week 24 were conducted for the Bleeding and Pelvic Discomfort and the activity subscales. A stratified Cochran-Mantel-Haenszel test, adjusted for stratification factors (region [North America vs rest of world] and baseline menstrual blood loss volume), was used for treatment comparisons.

RESULTS

Across both trials, 509 women were randomized to the relugolix combination therapy or placebo groups (April 2017-December 2018). Participants on relugolix combination therapy showed a statistically significant reduction in symptom severity (-33.5 vs -12.1; nominal P<.0001) and the Bleeding and Pelvic Discomfort subscale from baseline to week 24 when compared with those on placebo treatment (-48.4 vs -17.4; nominal P<.0001). Overall, the total Health-Related Quality of Life scores improved significantly from baseline to week 24 in the relugolix combination therapy group when compared with the placebo (+37.6 vs +13.1; nominal P<.0001). Responder analyses demonstrated that more women treated with relugolix combination therapy reported a clinically meaningful reduction in the Bleeding and Pelvic Discomfort subscale and an improvement in physical and social activities when compared with those treated with the placebo (nominal P<.0001).

CONCLUSION

After 24 weeks of treatment with relugolix combination therapy, women with symptomatic uterine fibroids experienced substantial improvements in health-related quality of life with all subscales showing improvement, including emotional well-being, physical and social activities, and sexual function. In addition, women reported substantial reductions in the overall symptom burden and distress caused by key fibroid-associated symptoms.

"I think people should be more aware:" Uterine fibroid experiences among women living in Indiana, USA

OBJECTIVE

To understand healthcare experiences among patients with uterine fibroids (fibroids) across the continuum of care, from early symptoms through diagnosis, treatment, and management, while also investigating health disparities.

METHODS

We conducted 20 semi-structured interviews with patients with fibroids. Interviews were transcribed verbatim and qualitatively analyzed using thematic analysis. Eligible participants were women aged 18 and over, residing within 75 miles of one of the two recruitment locations (Tippecanoe or Marion County) in Indiana, USA.

RESULTS

Women experienced myriad physical symptoms, which often manifested into psychological and sexual disturbances and infiltrated all aspects of daily life. Internet searches were frequently mentioned as their main information source. Fertility became a prominent factor in deciding treatment options. However, health disparities prevented some from receiving quality fibroids healthcare. Some women reported staying home during COVID-19 pandemic facilitated the management of physical symptoms. Overall, participants advocated for greater fibroids awareness and education.

CONCLUSION

Results highlight barriers and facilitators to fibroids-related decisions, behaviors, and outcomes. Translation of research to practice was guided by a combined Social-Ecological Model and social determinants of health framework for development of strategic interventions.

PRACTICE IMPLICATIONS

Interventions should aim to improve fibroids healthcare access, education and awareness, and patient-provider communication for minority, rural, and low socioeconomic status communities disproportionately impacted by fibroids.

Sacral injury and influencing factors after ultrasonic ablation of uterine fibroids ≤30 mm from the sacrum

PURPOSE

To study sacral injuries and influencing factors after ultrasonic ablation of uterine fibroids no more than 30 mm from the sacrum.

METHODS

A total of 406 patients with uterine fibroids who underwent percutaneous ultrasound ablation were analyzed retrospectively. All patients underwent contrast-enhanced magnetic resonance imaging (MRI) scans before and after high-intensity focused ultrasound. The abnormal signal intensity (low signal intensity on T1WI and high signal intensity on T2WI) on the postoperative MRIs was indicative of a sacral injury. The patients were divided into a sacrum injury group and a sacrum non-injury group. The relationship between fibroid characteristics, ultrasound ablation parameters, and injury was analyzed using univariate and multivariate analyses.

RESULTS

There were 139 cases of sacral injury (34.24%). When the distance from the fibroid's dorsal side to the sacrum was 0-10 mm, the risk assessment showed that the danger of sacral injury increased by 1.85 times and 3.03 times compared with that at a distance of 11-20 or 21-30 mm. Furthermore, the risk of sacral injury increased by 1.89 times and 3.23 times when the therapeutic dose (TD) of a fibroid was >500 KJ compared with that of a fibroid with TD= 250-500 KJ and <250 KJ.

CONCLUSION

A distance of 10 mm or less and a TD of >500 KJ were significantly correlated with sacral injury. The distance from the fibroid's dorsal side to the sacrum and the TD were the main causes of injury to the sacrum. A distance of 10 mm or less and a TD of >500 KJ carried higher injury risks, while a distance of 21-30 mm and a TD of <250 KJ were the most appropriate circumstances to reduce the risk of sacral injury.

Data-driven analyses to quantify information seeking behaviour for women with uterine fibroids

Uterine fibroids (UF) are noncancerous growths of the uterus and impact the livelihood of over 26 million women in the United States. Although UF may not have accompanying symptoms, for some women their presence leads to surgical treatment, which can be a difficult decision-making process. Web-scraping of online media is used to identify information-seeking behavior of women searching for UF treatment options. We synthesize the data to describe trends in UF treatment, including the identification of gaps between the information individuals are seeking (demand) and information that is publicly available as a resource (supply), which contributes to this study's creation of the term "information desert." We perform statistical analysis to understand information-seeking behavior, determine the gap between information supply and information demand, and determine the correlation between a doctor's treatment recommendation and a patient's treatment decision as a function of age, symptoms, and knowledge obtained about specific types of treatment.

Delayed expulsion of a large fibroid after transcervical radiofrequency ablation: A case report

Fibroids are the most common type of benign uterine tumor, which occur up to 68.6% of women. Hypermenorrhea is the most common symptom with a general prevalence of 40%-54%, followed by dysmenorrhea and low abdominal pain. Transcervical fibroids ablation was developed as a minimally invasive, incisionless treatment of fibroids in a short time. This method is safe and effective with an excellent record of safety. We present the case of a 40-year-old woman, who attended in our fibroid excellence center. She reported severe hypermenorrhea and dysmenorrhea. Family planning was definitely completed. Using vaginal ultrasonography a FIGO 2-5 fibroid of 5 cm in diameter was detected. Different treatment options were discussed: medical treatment, laparoscopic fibroidectomy, hysterectomy, and transcervical radiofrequency ablation with Sonata System. Because of advantages of transcervical radiofrequency ablation (minimal invasive treatment without incision, effectivity of method, short surgical time) the patient decided on this method. Three months later, the patient came to the first follow up. She reported a significant improvement of hypermenorrhea. A vaginal ultrasonography was carried out. The fibroid changed its position from FIGO 2-5 to FIGO 2. The patient was very satisfied with the result. After 2 months, she attended in our department again because of severe clear vaginal discharge. She had no bleeding, no pain as well as no fever. We examined her immediately. A fibroid expulsion was detected. The fibroid was removed vaginally. There was no severe bleeding during the operation and the fibroid could be removed completely. The surgery time was 25 minutes.

Informational Preferences of Women Seeking Treatment for Symptomatic Uterine Fibroids: A Qualitative Study

STUDY OBJECTIVE

To establish the informational needs and preferences of women navigating treatment options for symptomatic uterine fibroids.

DESIGN

Qualitative study using semistructured interviews.

SETTING

Academic institution.

PATIENTS

Participants had a diagnosis of symptomatic uterine fibroids with an active treatment plan.

INTERVENTIONS

Semistructured video interviews were conducted with female patients undergoing treatment for symptomatic uterine fibroids (n = 20). Women were recruited from the outpatient Center for Complex Gynecology in Chicago, IL. Interviews were recorded and transcribed verbatim. A codebook was developed based on the interview transcripts, and the finalized coding was used to conduct a thematic analysis.

MEASUREMENTS AND MAIN RESULTS

Four distinct themes emerged from the interviews: (1) Social supports-including social media-play an important role in informing patients' treatment choices; (2) Patients spend significant energy seeking additional information beyond their obstetrician-gynecologist; (3) Patients prioritize receiving full and complete information from their provider; and (4) Patients experience information-related delays in receiving care.

CONCLUSION

Patients seeking care for symptomatic uterine fibroids have strong preferences about both the quality and extent of information they receive from their gynecologists. Physicians treating these conditions must adapt to changing informational desires and consider expanding physician engagement with patients' social media needs.

Long-term evaluation of uterine fibroid embolisation using MRI perfusion parameters and patient questionnaires: preliminary results

BACKGROUND

Uterine fibroid embolisation (UFE) is an established treatment method for symptomatic uterine myomas. This study evaluates the efficacy of UFE using objective magnetic resonance imaging (MRI) data for size and perfusion analysis as well as patient questionnaires assessing fibroid-related symptoms.

METHOD

Patients underwent MR-Angiography before UFE and 4 days, 6 and 12 months after the procedure. The images were evaluated using dedicated software. Patient questionnaires were completed before UFE and at 12 months follow-up, focussing on the embolization procedure and symptoms associated with uterine fibroids. Statistical analysis of the questionnaires was performed using paired sample t-test and Wilcoxon signed rank test, while Kruskal-Wallis test and Friedman test were applied for MRI-analysis.

RESULTS

Eleven women were included. There was a significant reduction in fibroid-related symptoms. The volume reduction after 12 months was significant in both, uterus and myomas, after an initial increase in uterine volume at the first post-interventional MRI. The perfusion analysis showed that blood flow to the fibroids could be significantly reduced up to 12 months after UFE while uterine tissue was not affected.

CONCLUSION

This study shows that uterine fibroid embolisation induces a significant long-term decrease in myoma size and perfusion while healthy uterine tissue remains unaffected. Fibroid-related symptoms are reduced for the sake of improved quality of life.

Development of the Bleeding and Pelvic Discomfort Scale for Use in Women With Heavy Menstrual Bleeding Associated With Uterine Fibroids

OBJECTIVES

This study aimed to define a cardinal symptom burden measure based on items from the Uterine Fibroid Symptom and Quality of Life questionnaire for use as a clinical trial endpoint.

METHODS

Exploratory factor analysis was computed to assess the Uterine Fibroid Symptom and Quality of Life symptom severity scale factor structure, using phase 2 data. Pooled blinded data from phase 3 studies were used for the confirmatory factor analysis and the psychometric evaluation of the new measure. Exit interviews in 30 patients from phase 3 studies provided additional qualitative evidence. A meaningful change threshold was determined using anchor-based analyses supported by patient feedback in the exit interviews.

RESULTS

Three factors emerged from the exploratory factor analysis. Factor 1, called the bleeding and pelvic discomfort (BPD) scale, consists of cardinal symptoms, measuring menstrual distress owing to heavy bleeding, passing blood clots, and feeling tightness or pressure in pelvic area. Patients generally understood the items in the scale and the recall period as intended. The BPD scale had good item performance and internal consistency reliability, strong item-to-total correlations, good item discrimination, known-groups validity, and ability to detect change. A 20-point change on the BPD scale was determined as the clinically meaningful change threshold.

CONCLUSIONS

The BPD scale assesses symptom burden owing to bleeding, passing blood clots, and pelvic pressure. The subscale is based on a subset of items selected to measure the cardinal symptoms of uterine fibroids in a clinical trial setting. The responder threshold evaluates whether patients experience a meaningful treatment benefit over the on-treatment period.

Vitamin D and uterine fibroid growth, incidence, and loss: a prospective ultrasound study

OBJECTIVE

Fibroid treatments that have few side-effects and can preserve fertility are a clinical priority. We studied the association between serum vitamin D and uterine fibroid growth, incidence, and loss.

DESIGN

A prospective community cohort study (enrollment 2010-2012) with 4 study visits over 5 years to conduct standardized ultrasounds, measure 25-hydroxyvitamin D (25(OH)D), and update covariates.

SETTING

Detroit, Michigan area.

PATIENTS

Self-identified African American or Black women aged 23-35 at enrollment without previous clinical diagnosis of fibroids.

INTERVENTION(S)

Serum 25(OH)D measured using immunoassay or liquid chromatography-tandem mass spectrometry.

MAIN OUTCOME MEASURE(S)

The primary outcomes were fibroid growth, as measured by change in log volume per 18 months, and fibroid incidence (first detection of fibroid in previously fibroid-free uterus). Adjusted growth estimates from linear mixed models were converted to estimated difference in volume for high vs. low 25(OH)D. Incidence differences were estimated as hazard ratios from age-specific Cox regression. A secondary outcome fibroid loss (reduction in fibroid number between visits), was modeled using Poisson regression. Covariates (reproductive and hormonal variables, demographics, body mass index, current smoking) and 25(OH)D were modeled as time-varying factors.

RESULT(S)

At enrollment among 1,610 participants with ≥1 follow-up ultrasound, mean age was 29.2 years, 73% had deficient vitamin D (<20ng/mL), and only 7% had sufficient vitamin D (≥30ng/mL). Serum 25(OH)D ≥20ng/mL compared with <20ng/mL was associated with an estimated 9.7% reduction in fibroid growth (95% confidence interval [CI]: -17.3%, -1.3%), similar to the minimally adjusted estimate -8.4% (95% CI: -16.4, 0.3). Serum 25(OH)D ≥30ng/mL compared with <30ng/mL was associated with an imprecise 22% reduction in incidence (adjusted hazard ratio=0.78; 95% CI: 0.47, 1.30), similar to the unadjusted estimate of 0.84 (95% CI: 0.51, 1.39). The >30ng/mL group also had a 32% increase in fibroid loss (adjusted risk ratio=1.32; 95% CI: 0.95, 1.83).

CONCLUSION(S)

Our data support the hypothesis that high concentrations of vitamin D decrease fibroid development but are limited by the few participants with serum 25(OH)D ≥30ng/mL. Interventional trials that raise and maintain 25(OH)D concentrations >30ng/mL and then prospectively monitor fibroid development are needed to further assess supplemental vitamin D efficacy and determine optimal treatment protocols.

Association of Myomectomy With Anti-Müllerian Hormone Levels and Ovarian Reserve

OBJECTIVE

To assess whether open and minimally invasive myomectomy are associated with changes in postoperative ovarian reserve as measured by serum anti-müllerian hormone (AMH) level.

METHODS

This prospective cohort study included patients who were undergoing open abdominal myomectomy that used a tourniquet or minimally invasive (robot-assisted or laparoscopic) myomectomy that used vasopressin. Serum AMH levels were collected before the procedure and at 2 weeks, 3 months, and 6 months after surgery. The mean change in AMH level at each postsurgery timepoint was compared with baseline. The effect of surgical route on the change in AMH level at each timepoint was assessed by using multivariable linear regression. A subanalysis evaluated postoperative changes in AMH levels among the open myomectomy and minimally invasive myomectomy groups individually.

RESULTS

The study included 111 patients (mean age 37.9±4.7 years), of whom 65 underwent open myomectomy and 46 underwent minimally invasive myomectomy. Eighty-seven patients contributed follow-up data. Serum AMH levels declined significantly at 2 weeks postsurgery (mean change -0.30 ng/mL, 95% CI -0.48 to -0.120 ng/mL, P=.002). No difference was observed at 3 months or 6 months postsurgery. On multiple linear regression, open myomectomy was significantly associated with a decline in AMH level at 2 weeks postsurgery (open myomectomy vs minimally invasive myomectomy: β=-0.63±0.22 ng/mL, P=.007) but not at 3 months or 6 months. Subanalysis revealed a significant decline in mean serum AMH levels in the open myomectomy group at 2 weeks (mean change -0.46 ng/mL, 95% CI -0.69 to -0.25 ng/mL, P<.001) postsurgery but not at three or 6 months. In the minimally invasive myomectomy group, no significant differences in mean AMH levels were detected between baseline and any postoperative timepoint.

CONCLUSION

Myomectomy is associated with a transient decline in AMH levels in the immediate postoperative period, particularly after open surgery in which a tourniquet is used. Anti-müllerian hormone levels returned to baseline by 3 months after surgery, indicating that myomectomy is not associated with a long-term effect on ovarian reserve, even with the use of a tourniquet to decrease blood loss.

FUNDING SOURCE

This study was funded in part by a Roche Diagnostics Investigator-Initiated Study Grant.

Interdisciplinary model-informed drug development for extending duration of elagolix treatment in patients with uterine fibroids

AIM

Elagolix, a gonadotropin-releasing hormone receptor antagonist, was recently approved for heavy menstrual bleeding associated with uterine fibroids (UF, Oriahnn) at a dose of 300 mg twice daily (BID) in combination with add-back therapy (oestradiol 1 mg/norethindrone acetate 0.5 mg [E2/NETA] once daily) for 24 months use. The limited duration of treatment is related to elagolix dose- and duration-dependent decrease in oestrogen that is mechanistically linked to changes in bone mineral density (BMD). The work herein supported the extended treatment duration of 24 months.

METHODS

An integrated exposure-response and epidemiological modelling framework of elagolix effects on femoral neck BMD (FN-BMD), informed by real-world data and phase 3 clinical trials data, was developed to predict the time course and magnitude of changes in BMD and its relation to risk of bone fracture in women with UF.

RESULTS

Model results indicated that women treated with elagolix 300 mg BID + E2/NETA in the long term (ie, >24 months) may experience less than 1% loss in FN-BMD per year, relative to placebo. The exposure-response model simulations and clinical risk factors were used to estimate 10-year risk of fractures using the clinically validated Fracture Risk Assessment Tool (FRAX). The impact of elagolix 300 mg BID + E2/NETA treatment on the 10-year risk of hip or major osteoporotic fractures estimated from the FRAX model was minimal compared to that of placebo.

CONCLUSION

The elagolix integrated exposure-BMD analysis and translation to fracture risk provided an interdisciplinary model-informed drug development framework for clinical benefit-risk evaluation and enabled approval of longer treatment duration to benefit the patient.

Development of a core minimum data set to advance real-world evidence generation for uterine fibroids treatment technologies

Objectives

The accumulation of data through a prospective, multicenter coordinated registry network (CRN) is a robust and cost-effective way to gather real-world evidence on the performance of uterine fibroids treatment technologies for device-based and intervention-based studies. To develop the CRN, a group of uterine fibroids experts, consisting of representatives from professional societies, the US Food and Drug Administration, academia, industry, and the patient community, was convened to discuss the role and feasibility of the CRN and to identify the core data elements needed to assess uterine fibroid treatment technologies.

Design

A Delphi method approach was employed to achieve consensus on a core minimum data set for the CRN. A series of surveys were sent to the panel and answered by each expert anonymously and individually. Results from the surveys were collected, collated, and analyzed by a study design team from Weill Cornell Medicine. Questions for the next round were based on the analysis process and discussed with group members via a conference call. This process was repeated twice over a 3-month time period until consensus was achieved.

Results

Twenty-nine experts participated in the Delphi surveys, which began with an initial list of 200 data elements. The working group reached final consensus on 97 data elements capturing patient medical history, imaging data, procedure-related data, post-procedure data, and long-term follow-up data.

Conclusions

The CRN successfully convened an expert panel on uterine fibroids treatment technologies and used the Delphi method to produce a consensus-based core set of data elements. These identified data elements include important outcomes related to efficacy and safety and thus, influence patient, provider, and regulatory decision-making about treatments for uterine fibroids. Finally, the core data elements provide the foundation of the infrastructure needed for the CRN that will allow for the comparative study of uterine fibroid treatment devices and technologies.

Perceptions of Ethnoracial Factors in the Management and Treatment of Uterine Fibroids

BACKGROUND

Uterine fibroids are non-cancerous neoplasms of the uterus. Women of color, including non-Hispanic Black/African American women and Hispanic/Latinas, have a higher uterine fibroid prevalence, incidence, and disease burden compared to non-Hispanic White women. Therefore, understanding ethnoracial factors in the diagnosis and treatment of uterine fibroids in women of color is critical. This study provides insight on the ethnoracial factors and cultural barriers experienced by women of color in the management and treatment of uterine fibroids.

METHODS

Women were recruited via The Fibroid Foundation, a nonprofit that provides uterine fibroid support and education. Women who were interested completed an online screening survey. Eligible participants were interviewed via phone. Transcribed audio recordings were qualitatively analyzed using the principles of grounded theory.

RESULTS

Forty-seven women of reproductive age who were diagnosed with uterine fibroids and received U.S.-based care participated in a semi-structured interview exploring experiences with uterine fibroid diagnosis and management. Twenty-eight women self-identified as Black, Latina, or other ethnicity. Women of color reported fibroid symptoms that significantly disrupted their work and home life. Women of color also reported perceptions that their race/ethnicity impacted their uterine fibroid treatment, including negative interpersonal provider-patient interactions. These perceptions engendered feelings of skepticism towards the medical system based on historical injustices and/or their own negative experiences and led some to go without longitudinal care.

CONCLUSION

Cultural and familial factors have significant impact on uterine fibroid diagnosis and management. Greater attention to culturally sensitive care and potential bias reduction in the treatment of uterine fibroids should be a priority.

Oral Gonadotropin-Releasing Hormone Antagonists in the Treatment of Uterine Myomas: A Systematic Review and Network Meta-analysis of Efficacy Parameters and Adverse Effects

OBJECTIVE

The aim of this systematic review is to gather and synthesize evidence regarding the use of oral gonadotrophin-releasing hormone (GnRH) antagonist for the treatment of bleeding associated with uterine myomas.

DATA SOURCES

Web of Science, and MEDLINE databases were searched electronically on March 5, 2021, using combinations of the relevant Medical Subject Headings terms and keywords. The search was restricted to the English language and to human studies.

METHODS OF STUDY SELECTION

Only randomized controlled trials involving patients with heavy menstrual bleeding associated with uterine myomas treated with different doses of oral nonpeptide GnRH antagonists with or without add-back therapy were included. Studies comparing oral nonpeptide GnRH antagonists with treatments other than placebo were also excluded.

TABULATION, INTEGRATION, AND RESULTS

A total of 5 randomized trials including 2463 women were included in the analyses. Included studies were found to be at low risk of bias. When treatments were compared against placebo, the top 3 treatments for bleeding suppression were elagolix 600 mg, 400 mg, and 200 mg without add-back. Elagolix 600 mg without add-back therapy had a significantly higher risk of amenorrhea than lower doses of elagolix with and without add-back and relugolix as well. Uterine volume changes were more pronounced in therapies without add-back. All treatments were associated with significantly improved quality of life scores, both for myoma symptom-related and overall health-related scores. With the exception of relugolix with high-dose add-back, all treatments significantly increased low-density lipoprotein (LDL) levels. Again, all treatment modalities except for elagolix 200 mg without add-back significantly increased LDL-to-HDL ratio. The increase was highest for treatment without add-back therapy.

CONCLUSION

Oral GnRH antagonists seem to be effective for myoma-associated bleeding and for improving quality of life. The safety profile is acceptable for short-term use, but lipid metabolism is affected.

Uterine artery embolisation versus myomectomy for premenopausal women with uterine fibroids wishing to avoid hysterectomy: the FEMME RCT

BACKGROUND

Uterine fibroids are the most common tumour in women of reproductive age and are associated with heavy menstrual bleeding, abdominal discomfort, subfertility and reduced quality of life. For women wishing to retain their uterus and who do not respond to medical treatment, myomectomy and uterine artery embolisation are therapeutic options.

OBJECTIVES

We examined the clinical effectiveness and cost-effectiveness of uterine artery embolisation compared with myomectomy in the treatment of symptomatic fibroids.

DESIGN

A multicentre, open, randomised trial with a parallel economic evaluation.

SETTING

Twenty-nine UK hospitals.

PARTICIPANTS

Premenopausal women who had symptomatic uterine fibroids amenable to myomectomy or uterine artery embolisation were recruited. Women were excluded if they had significant adenomyosis, any malignancy or pelvic inflammatory disease or if they had already had a previous open myomectomy or uterine artery embolisation.

INTERVENTIONS

Participants were randomised to myomectomy or embolisation in a 1 : 1 ratio using a minimisation algorithm. Myomectomy could be open abdominal, laparoscopic or hysteroscopic. Embolisation of the uterine arteries was performed under fluoroscopic guidance.

MAIN OUTCOME MEASURES

The primary outcome was the Uterine Fibroid Symptom Quality of Life questionnaire (with scores ranging from 0 to 100 and a higher score indicating better quality of life) at 2 years, adjusted for baseline score. The economic evaluation estimated quality-adjusted life-years (derived from EuroQol-5 Dimensions, three-level version, and costs from the NHS perspective).

RESULTS

A total of 254 women were randomised - 127 to myomectomy (105 underwent myomectomy) and 127 to uterine artery embolisation (98 underwent embolisation). Information on the primary outcome at 2 years was available for 81% (n = 206) of women. Primary outcome scores at 2 years were 84.6 (standard deviation 21.5) in the myomectomy group and 80.0 (standard deviation 22.0) in the uterine artery embolisation group (intention-to-treat complete-case analysis mean adjusted difference 8.0, 95% confidence interval 1.8 to 14.1, p = 0.01; mean adjusted difference using multiple imputation for missing responses 6.5, 95% confidence interval 1.1 to 11.9). The mean difference in the primary outcome at the 4-year follow-up time point was 5.0 (95% CI -1.4 to 11.5; p = 0.13) in favour of myomectomy. Perioperative and postoperative complications from all initial procedures occurred in similar percentages of women in both groups (29% in the myomectomy group vs. 24% in the UAE group). Twelve women in the uterine embolisation group and six women in the myomectomy group reported pregnancies over 4 years, resulting in seven and five live births, respectively (hazard ratio 0.48, 95% confidence interval 0.18 to 1.28). Over a 2-year time horizon, uterine artery embolisation was associated with higher costs than myomectomy (mean cost £7958, 95% confidence interval £6304 to £9612, vs. mean cost £7314, 95% confidence interval £5854 to £8773), but with fewer quality-adjusted life-years gained (0.74, 95% confidence interval 0.70 to 0.78, vs. 0.83, 95% confidence interval 0.79 to 0.87). The differences in costs (difference £645, 95% confidence interval -£1381 to £2580) and quality-adjusted life-years (difference -0.09, 95% confidence interval -0.11 to -0.04) were small. Similar results were observed over the 4-year time horizon. At a threshold of willingness to pay for a gain of 1 QALY of £20,000, the probability of myomectomy being cost-effective is 98% at 2 years and 96% at 4 years.

LIMITATIONS

There were a substantial number of women who were not recruited because of their preference for a particular treatment option.

CONCLUSIONS

Among women with symptomatic uterine fibroids, myomectomy resulted in greater improvement in quality of life than did uterine artery embolisation. The differences in costs and quality-adjusted life-years are very small. Future research should involve women who are desiring pregnancy.

Subjective theories of illness in fibroid and endometriosis patients: Similarities, differences, and influencing factors

Introduction:

The aim of this study was to compare the subjective theories of illness in patients with fibroids and patients with endometriosis, and to identify potential factors influencing them.

Methodology:

Participating patients were recruited via three specialized centers for fibroids and endometriosis. To assess their subjective theories concerning the cause of their illness, we used a questionnaire based on the revised Illness Perceptions Questionnaire (IPQ-R). We also gathered and evaluated data relating to sociodemographic factors and psychological distress or possible anxieties using the Kessler Psychological Distress Scale (K10) and the Generalised Anxiety Disorder Assessment (GAD-7).

Results:

We were able to analyze data from 201 patients with fibroids and 212 patients with endometriosis. About 94.4% of the patients had one or more subjective theories concerning the cause of their illness. Both groups perceived “stress or worry” to be the most probable cause of their illness. Compared to endometriosis patients, patients with fibroids were more likely to assume “aging” and “heredity” as the cause of their illness. Endometriosis patients, on the other hand, were more likely to choose theories pertaining to the “environmental influences and immune system” category. The patients’ age, formal education, and conspicuous score values in the K10 or GAD-7 questionnaire proved to be important factors influencing their beliefs about the cause of illness.

Conclusion:

Patients perceive stress and psychological strain as possible causes for their illness. It might be beneficial to take this information into account in conversations between doctors and patients and when drawing up psychosomatic-gynecological treatment plans.

The Burden of Uterine Fibroids from the Perspective of US Women Participating in Open-Ended Interviews

BACKGROUND

Research on women's perspective of uterine fibroids (UF) experiences using their own words is limited. This study aimed to provide new insights on the symptoms experienced and their impacts on daily life.

METHODS

Interview substudy in 30 US women with heavy menstrual bleeding (HMB) associated with UF who completed one of two phase 3, randomized, double-blind, placebo-controlled trials (LIBERTY 1 and 2; ClinicalTrials.gov identifiers: NCT03049735, NCT03103087). Women who consented to participate in this substudy were interviewed after their last clinical trial study visit. Concepts (i.e., symptoms and impacts) of importance to women were determined via open-ended questions, and the frequency of symptoms and their impacts, including the relationship between pain and menstruation, were assessed. Data were analyzed using established qualitative research methods, including grounded theory and constant comparative methods, and concept saturation was assessed.

RESULTS

Fifteen unique symptoms of UF emerged: the most commonly reported were HMB (n = 30, 100.0%), pelvic pain (n = 28, 93.3%), and passing of blood clots (n = 24, 80.0%). In total, 25 unique impacts were identified across eight concepts: physical impacts, activities of daily living, sleep, emotional impacts, sex life, social impacts, work and school, and financial impacts. Concept saturation was achieved for both symptoms and impacts.

CONCLUSION

This study provides data on the symptoms experienced by women with HMB associated with UF, as well as the negative impacts of these symptoms as reported using their own words. The study findings confirm the significant burden associated with symptomatic UF.

Anxiety, Depression, and Quality of Life After Procedural Intervention for Uterine Fibroids

Background: Quality of life (QOL) and psychological health has been reported to be decreased among women with gynecological conditions such as uterine fibroids (UFs). Materials and Methods: Women enrolled in the Comparing Options for Management: PAtient-centered REsults for Uterine Fibroids (COMPARE-UF) registry, receiving procedural therapy for symptomatic UFs, were eligible for this analysis if they completed a series of health-related QOL surveys administered at three time points (baseline, 6-12 weeks postprocedure, and 1 year postprocedure; n = 1486). Ethical approval for this study was obtained at each recruiting site and the coordinating center (NCT02260752, clinicaltrials.gov). Results: More than 26% (n = 393) of women reported moderate anxiety/depression on the baseline anxiety/depression domain of the Euro-QOL 5-dimension instrument. At both the 6-12 weeks and 1-year postprocedural follow-up, there was significant improvement in the UF QOL symptom severity score (p < 0.001, p < 0.001), the total UF symptom QOL score (p < 0.001, p < 0.001), and the Euro-QOL 5-dimension visual analog scale (p < 0.001, p = 0.004) compared with the preprocedural baseline scores. The reporting of anxiety/depression decreased by 66.4% among women who were at baseline, whereas 5.6% of women previously reporting no anxiety/depression reported anxiety/depression at the 1-year follow-up. Conclusion: UF symptoms were more severe among women reporting anxiety/depression at baseline. At the 1-year follow-up, health-related QOL scores improved among all women and the prevalence of anxiety/depression decreased in most, but not all women, whereas severity of anxiety/depression worsened in a small percentage of women (5.6%). Overall, these results suggest that UF treatment improves symptoms of anxiety/depression associated with symptomatic UFs.

Epigenomic and enhancer dysregulation in uterine leiomyomas

BACKGROUND

Uterine leiomyomas, also known as uterine fibroids or myomas, are the most common benign gynecological tumors and are found in women of reproductive and postmenopausal age. There is an exceptionally high prevalence of this tumor in women by the age of 50 years. Black women are particularly affected, with an increased incidence, earlier age of onset, larger and faster growing fibroids and greater severity of symptoms as compared to White women. Although advances in identifying genetic and environmental factors to delineate these fibroids have already been made, only recently has the role of epigenomics in the pathogenesis of this disease been considered.

OBJECTIVE AND RATIONALE

Over recent years, studies have identified multiple epigenomic aberrations that may contribute to leiomyoma development and growth. This review will focus on the most recent discoveries in three categories of epigenomic changes found in uterine fibroids, namely aberrant DNA methylation, histone tail modifications and histone variant exchange, and their translation into altered target gene architecture and transcriptional outcome. The findings demonstrating how the altered 3D shape of the enhancer can regulate gene expression from millions of base pairs away will be discussed. Additionally, translational implications of these discoveries and potential roadblocks in leiomyoma treatment will be addressed.

SEARCH METHODS

A comprehensive PubMed search was performed to identify published articles containing keywords relevant to the focus of the review, such as: uterine leiomyoma, uterine fibroids, epigenetic alterations, epigenomics, stem cells, chromatin modifications, extracellular matrix [ECM] organization, DNA methylation, enhancer, histone post-translational modifications and dysregulated gene expression. Articles until September 2021 were explored and evaluated to identify relevant updates in the field. Most of the articles focused on in the discussion were published between 2015 and 2021, although some key discoveries made before 2015 were included for background information and foundational purposes. We apologize to the authors whose work was not included because of space restrictions or inadvertent omission.

OUTCOMES

Chemical alterations to the DNA structure and of nucleosomal histones, without changing the underlying DNA sequence, have now been implicated in the phenotypic manifestation of uterine leiomyomas. Genome-wide DNA methylation analysis has revealed subsets of either suppressed or overexpressed genes accompanied by aberrant promoter methylation. Furthermore, differential promoter access resulting from altered 3D chromatin structure and histone modifications plays a role in regulating transcription of key genes thought to be involved in leiomyoma etiology. The dysregulated genes function in tumor suppression, apoptosis, angiogenesis, ECM formation, a variety of cancer-related signaling pathways and stem cell differentiation. Aberrant DNA methylation or histone modification is also observed in altering enhancer architecture, which leads to changes in enhancer-promoter contact strength, producing novel explanations for the overexpression of high mobility group AT-hook 2 and gene dysregulation found in mediator complex subunit 12 mutant fibroids. While many molecular mechanisms and epigenomic features have been investigated, the basis for the racial disparity observed among those in the Black population remains unclear.

WIDER IMPLICATIONS

A comprehensive understanding of the exact pathogenesis of uterine leiomyoma is lacking and requires attention as it can provide clues for prevention and viable non-surgical treatment. These findings will widen our knowledge of the role epigenomics plays in the mechanisms related to uterine leiomyoma development and highlight novel approaches for the prevention and identification of epigenome targets for long-term non-invasive treatment options of this significantly common disease.

Ultrasounds in cancer therapy: A summary of their use and unexplored potential

Ultrasounds (US) are a non-ionizing mechanical wave, with less adverse effects than conventional pharmacological or surgical treatments. Different biological effects are induced in tissues and cells by ultrasound actuation depending on acoustic parameters, such as the wave intensity, frequency and treatment dose. This non-ionizing radiation has considerable applications in biomedicine including surgery, medical imaging, physical therapy and cancer therapy. Depending on the wave intensity, US are applied as high-intensity ultrasounds (HIUS) and low-intensity pulsed ultrasounds (LIPUS), with different effects on cells and tissues. HIUS produce thermal and mechanical effects, resulting in a large localized temperature increase, leading to tissue ablation and even tumor necrosis. This can be achieved by focusing low intensity waves emitted from different electrically shifted transducers, known as high-intensity focused ultrasounds (HIFU). LIPUS have been used extensively as a therapeutic, surgical and diagnostic tool, with diverse biological effects observed in tissues and cultured cells. US represent a non-invasive treatment strategy that can be applied to selected areas of the body, with limited adverse effects. In fact, tumor ablation using HIFU has been used as a curative treatment in patients with an early-stage pancreatic tumor and is an effective palliative treatment in patients with advanced stage disease. However, the biological effects, dose standardization, benefit-risk ratio and safety are not fully understood. Thus, it is an emerging field that requires further research in order to reach its full potential.

Vitamin D and green tea extracts for the treatment of uterine fibroids in late reproductive life: a pilot, prospective, daily-diary based study

OBJECTIVE

The beneficial effects of Vitamin D (VD) and Epigallocatechin gallate (EGCG), a polyphenol of green tea, on the growth of uterine fibroids (UF) were previously described in vitro and in vivo. We have decided to investigate their simultaneous administration in women with UFs in late reproductive life.

METHODS

>40 years old n = 16 premenopausal women with intramural (IM) or subserosal (SS) UF of ≥3 cm or several UFs of different sizes, even smaller but with a total diameter ≥3 cm but <10 cm, without further concomitant organic causes of abnormal uterine bleeding, treated with EGCG 300 mg, Vitamin B6 10 mg and VD 50 µg/day for 90 days. Women completed a diary on a daily basis to obtain information about bleeding and pelvic pain.

RESULTS

We have observed a significant reduction in UF's mean size both at patient's (-17.8%, p = .03) and at single UF's level (-37.3%, p = .015). The effect was more evident in women with predominant IM (p = .016) in comparison to SS UFs. No significant changes were observed for uterine and ovarian volume and endometrial thickness during treatment. We reported a significant decrease in menstrual flow length of 0.9 day (p = .04) with no modification in cycle length, menstrual flow intensity and menstrual pain intensity. The satisfaction with treatment was in general very high, with no adverse effects reported.

CONCLUSION

The concomitant administration of VD and EGCG represents a promising treatment of UF in women of late reproductive life for which hormonal manipulation is not foreseen.

Transcervical radiofrequency ablation of fibroids that are 5 cm or larger in women with abnormal uterine bleeding

INTRODUCTION

Fibroids are the most common benign uterine tumors. Transcervical radiofrequency ablation with the Sonata® System offers a minimally invasive, incisionfree, organ-preserving therapy, with intraoperative visualization of fibroids using intrauterine ultrasound guidance. To demonstrate the effectiveness of transcervical radiofrequency ablation of fibroids that are 5 cm or larger using the Sonata® System, this retrospective analysis was collected.

METHOD

151 patients have been treated with this method in our department up to the time of this analysis. Only patients with at least one fibroid of ≥5 cm and with bleeding symptoms, who were treated with the Sonata® System were included in this retrospective study. A total of 50 patients were included in the study and 57 fibroids were treated.

RESULTS

A total of 57 fibroids were detected and treated, however FIGO 1 and 2 fibroids (in total three fibroids were excluded). The smallest fibroid was 4 cm and the largest fibroid was 12 cm. A single ablation was performed in 18 cases, two ablation steps in 16 cases, three ablation steps in 13 cases, and more than three ablation steps in three cases. Depending on ablation steps, the shortest ablation time was 3 min 15 s and the longest ablation time was 25 min 6 s, with an average time of 9 min 12 s. 86% of patients reported an improvement of symptoms Conclusion: Thus, the Sonata® System is a simple, minimally invasive, rapid and successful method that shows significant improvement of symptoms even in large myomas from ≥5 cm.

Body mass index and vitamin D as risk factors for the development of uterine leiomyomas in Mexican women

Objective:

The objective of the present study was to determine if body mass index and vitamin D levels are risk factors for the development of uterine leiomyomas in Mexican women.

Methods:

A cross-sectional study was designed. Inclusion criteria were women between 20 and 55 years with a suspect of uterine leiomyomas. Transvaginal ultrasonography was made to confirm the diagnosis and clinical variables were collected. Vitamin D levels were measured in serum by chemiluminescence immunoassay. Binary linear regression analysis was conducted to assess the predictors of uterine leiomyomas.

Results:

A total of 106 patients were evaluated, the mean age was 41.4 ± 8.0 years. The serum levels of vitamin D were insufficient in 94 (88.7%) and 82 (77.3%) has overweight or obesity. However, only 50 (47.2%) of participants have a diagnostic of uterine leiomyomas. BMI not increased the probability of having insufficient levels of vitamin D or uterine leiomyomas. Only, age (> 45 years) and levels of vitamin D (<30 ng/mL) were predictors of uterine leiomyomas (OR 10.345, 95% CI 2.737–39.095; p = 0.001; and OR 2.26, 95% CI 1.011–5.073; p = 0.014), respectively.

Conclusions:

Insufficient levels of vitamin D are common in Mexican women. Age and hypovitaminosis D are possible risk factors in the development of uterine leiomyomas in Mexican women.

Iron Deficiency Anemia With a Life-Threatening Low Hemoglobin Level

Iron deficiency anemia (IDA) accounts for roughly half of all anemia cases globally. Menorrhagia and menstrual cycle disorders render women of childbearing age more prone to IDA. One of the leading causes of menorrhagia is uterine fibroids (leiomyomas), which are defined as hyperplastic, usually benign, overgrowths of uterine wall muscle and connective tissue. This is a case report of a 45-year-old woman who came to the emergency department complaining of progressive fatigue and dizziness for two months. She was admitted as a case of life-threatening IDA with a hemoglobin level of 3.0 g/dL. She was ambulatory and hemodynamically stable without any features of severe anemia. Pelvic ultrasound was performed and revealed uterine fibroids. After partial correction of the anemia, she underwent a total hysterectomy as a definitive treatment.

Surgical Treatment of "Large Uterine Masses" in Pregnancy: A Single-Center Experience

Uterine myomas or uterine fibroids are the most common benign uterine masses affecting women. The management of large myoma during pregnancy is challenging, and surgical treatment is a possible option. We report nine cases of pregnant women affected by uterine masses larger than 10 cm, who underwent surgical treatment during the second trimester of pregnancy. In all cases, the masses were preconceptionally unknown and diagnosed during the first trimester. In eight cases, no maternal and fetal complications arose during or after surgical treatment and delivery occurred at full term of pregnancy. In one case, spontaneous abortion was recorded. In all cases, histologic diagnosis demonstrated the benign nature. Women affected by large uterine masses diagnosed for the first time in pregnancy could be taken into consideration for surgical treatment in a referral center during the second trimester.

What We Know about the Long-Term Risks of Hysterectomy for Benign Indication-A Systematic Review

Hysterectomy is the most common treatment option in women with uterine fibroids, providing definitive relief from the associated burdensome symptoms. As with all surgical interventions, hysterectomy is associated with risk of complications, short-term morbidities, and mortality, all of which have been described previously. However, information on the potential long-term risks of hysterectomy is only recently becoming available. A systematic literature review was performed to identify studies published between 2005 and December 2020 evaluating the long-term impact of hysterectomy on patient outcomes. A total of 29 relevant studies were identified. A review of the articles showed that hysterectomy may increase the risk of cardiovascular events, certain cancers, the need for further surgery, early ovarian failure and menopause, depression, and other outcomes. It is important to acknowledge that the available studies examine possible associations and hypotheses rather than causality, and there is a need to establish higher quality studies to truly evaluate the long-term consequences of hysterectomy. However, it is of value to consider these findings when discussing the benefits and risks of all treatment options with patients with uterine fibroids to allow for preference-based choices to be made in a shared decision-making process. This is key to ensuring that patients receive the treatment that best meets their individual needs.

A feasibility analysis of the ArcBlate MR-guided high-intensity focused ultrasound system for the ablation of uterine fibroids

Purpose

Uterine fibroids are benign gynecologic tumors and commonly occur in women by the age of 50. Women with symptomatic uterine fibroids generally receive surgical intervention, while they do not favor the invasive therapies. To evaluate the feasibility and safety of a novel magnetic resonance-guided high-intensity focused ultrasound (MRgHIFU) modality, ArcBlate, in the treatment of uterine fibroids.

Methods

Nine patients with uterine fibroids and one patient with adenomyosis were treated with ArcBlate MRgHIFU. Tumor size and quality of life were evaluated postoperatively at 1 and 3 months by magnetic resonance imaging (MRI) and the 36-Item Short Form Survey (SF-36), respectively.

Results

All patients completed the ArcBlate MRgHIFU procedure and there were no treatment-related adverse effects either during the procedure or during the 3 months of follow-up. Despite limiting the ablation volume to under 50% of the treated fibroid volume as a safety precaution, tumor volumes were markedly reduced in four patients by 15.78–58.87% at 3-month post-treatment. Moreover, SF-36 scale scores had improved at 3 months from baseline by 2–8 points in six patients, indicating relief of symptoms and improved quality of life.

Conclusion

This study evidence demonstrates the safety and feasibility of ArcBlate MRgHIFU and suggests its potential for treating uterine fibroids.

Low plasma vitamin D as a predictor of uterine fibroids in a nigerian population

Background

Uterine fibroid is the most common benign tumour of the uterus and the exact cause is unknown. Vitamin D has been found to inhibit cell proliferation and enhance apoptosis in vitro.

Aim

The aim of this study is to compare the plasma level of Vitamin D among women with uterine fibroids and those without uterine fibroids.

Materials and Methods

This was an analytical cross-sectional study conducted among women with uterine fibroids and those without uterine fibroids. An interviewer-administered questionnaire was used to obtain relevant information. Five millilitres of venous blood was obtained for plasma Vitamin D assay. Data analysis was performed using the SPSS version 22. Level of significance was set at P < 0.05.

Results

There were 100 participants recruited for the study. The mean age of the participants with uterine fibroid was 35.06 ± 6.6 years and that of controls was 33.28 ± 7 years. The mean plasma level of Vitamin D for all the participants was 12.47 ± 7.53 ng/ml. The mean plasma level of Vitamin D in those with uterine fibroids was significantly lower than in those without uterine fibroid (10.16 ± 7.78 vs. 14.35 ± 6.8; t = 2.517, P = 0.014). It also shows that 1 unit increase in Vitamin D level will reduce the risk of developing uterine fibroids by 8% (odds ratio = 0.92, 95% confidence interval = 0.86-0.99).

Conclusion

The predictors of uterine fibroids were fewer hours spent outdoors, middle social class and low Vitamin D levels.

Relugolix for oral treatment of uterine leiomyomas: a dose-finding, randomized, controlled trial

BACKGROUND

Uterine leiomyomas are the most common neoplasm affecting women and frequently cause heavy menstrual bleeding and pain. Gonadotropin-releasing hormone (GnRH) receptor antagonists provide fast symptom relief and show promise as a medical (non-surgical) treatment option and as a presurgical treatment to reduce leiomyoma size. The aim of this study was to evaluate the efficacy and safety of three dose levels of oral relugolix, a small molecule GnRH receptor antagonist, in Japanese women with uterine leiomyomas and heavy menstrual bleeding.

METHODS

This phase 2, multicenter, double-blind, parallel-group study was conducted at 36 sites in Japan in women with uterine leiomyomas and heavy menstrual bleeding, defined as a pictorial blood loss assessment chart (PBAC) score of ≥ 120 in one menstrual cycle. Patients were randomized 1:1:1:1 to relugolix 10, 20, or 40 mg, or placebo, orally once daily for 12 weeks. The primary endpoint was the proportion of patients with a total PBAC score of < 10 from week 6 to 12. A sample size of 50 patients per group was estimated to provide ≥ 95% power, based on the comparison of relugolix 40 mg with placebo using a chi-square test with a significance level of 5% (two-sided).

RESULTS

From November 2011 to September 2012, 216 patients were randomized and 214 patients (99.1%) were analyzed. The proportion (difference vs. placebo) of patients that achieved the primary endpoint in the placebo and 10-, 20-, and 40-mg relugolix groups were 0%, 20.8% (95% confidence interval [CI]: 9.3-32.3, P < .001), 42.6% (95% CI: 29.4-55.8, P < .001), and 83.3% (95% CI: 73.4-93.3, P < .001), respectively. Though treatment-emergent adverse events were similar between the 20- and 40-mg groups, the incidence rates were more frequent compared with the placebo group. Most of these adverse events were mild or moderate in intensity.

CONCLUSIONS

Relugolix decreased menstrual blood loss in women with uterine leiomyomas in a dose-response manner, and was generally well tolerated.

Patient Recommendations for Shared Decision-Making in Uterine Fibroid Treatment Decisions

Uterine fibroids are noncancerous tumors associated with significant morbidity among symptomatic patients. While medical and surgical treatments have expanded, hysterectomy remains common. We interviewed women diagnosed with uterine fibroids (n = 47) to explore their experiences and recommendations for shared decision-making. A majority were non-Hispanic Black, highly educated (51.1%), and had graduate degrees (40.4%). Participants with both positive and negative provider experiences expressed a desire for a more proactive therapeutic approach, including a presentation by their provider of the spectrum of medical and surgical treatment options, and greater provider recognition of the impact of symptoms on quality of life. Women advocated for expanded shared decision-making that acknowledged their contribution to their own treatment plan and felt early screening and improved patient/provider education of uterine fibroid symptoms would facilitate greater congruence between treatment approaches and patient goals. Perceptions of insufficient input into their treatment plans frequently served as a barrier to care-seeking and treatment acceptance among women with uterine fibroid symptoms. Improved discussion of treatment options in the context of the unique symptom burden and values of the patient may facilitate greater provider trust and acceptance of uterine fibroid treatment.

Current approaches to overcome the side effects of GnRH analogs in the treatment of patients with uterine fibroids

Introduction: Uterine fibroids (UFs) are the most prevalent benign neoplastic threat originating from myometria of reproductive age women, with a profound financial load valued in hundreds of billions of dollars. Unfortunately, there is no curative treatment so far except surgery and available pharmacological treatments are restricted for short-term treatment options. Thus, there is a large unmet need in the UF space for noninvasive therapeutics.Areas covered: The authors reviewed the literature available for the utility of gonadotropin-releasing hormone (GnRH) analogs in women with UFs. We also focused on clinical studies exploring the therapeutic benefits of novel oral non-peptide GnRH antagonists that were recently approved by the U.S. Food and Drug Administration (FDA) in combination with estradiol/norethindrone acetate for the management of heavy menstrual bleeding associated with UFs in premenopausal women.Expert opinion: The results regarding the efficacy of new-generation oral GnRH-antagonists, such as elagolix, relugolix and linzagolix, are promising and offer potential prospect for the future therapy of UFs. However, these antagonists must be combined with hormonal add-back therapy to minimize the resultant hypoestrogenic side effects such as bone loss.

Myoma Expulsion after Uterine Artery Embolization

Introduction

Uterine leiomyomas are the most common benign pelvic tumors in women over 35 years and can be symptomatic or asymptomatic. Among the main treatment strategies, there are hormone therapy, hysterectomy, myomectomy, and uterine artery embolization (UAE), a recent and promising treatment for patients who wish to avoid hysterectomy. Ideal candidates for UAE are women with symptomatic uterine leiomyomas that present no desire for pregnancy, premenopausal and heavy menstrual bleeding, or dysmenorrhea caused by intramural fibroids. Case Presentation. A 36-year-old female diagnosed with leiomyomas and an extensive history of failed previous treatments who, in order to preserve her uterus, underwent UAE and had tumor expulsion 15 days after the procedure. The patient remained eight months in amenorrhea and, currently, presents normal hormone levels and irregular periods.

Conclusion

UAE presents itself as a minimally invasive procedure and as an efficient alternative for those patients who wish to preserve their uteri and also improve their symptoms and quality of life.

Uterine leiomyoma is associated with the risk of developing endometriosis: A nationwide cohort study involving 156,195 women

Objective

Evidence for an association between uterine leiomyoma and increased risk of endometriosis is limited by small sample sizes and short follow-up periods. We assessed this association in a large nationwide sample with 14 years of data.

Design

Data were sourced from Taiwan’s Longitudinal Health Insurance Database 2000 (LHID2000).

Materials and methods

We identified 31,239 women aged ≥20 years diagnosed with uterine leiomyoma (International Classification of Disease, Ninth Revision, Clinical Modification [ICD-9-CM] code 218) between Jan 1, 2000 and Dec 31, 2012, who were matched with 124,956 controls (1:4) by 5-year age groups and year of diagnosis. Follow-up was from the date of LHID2000 entry to the first occurrence of endometriosis, loss to follow-up, insurance termination, or until December 31, 2013, whichever was earlier.

Results

In Cox regression analysis, the adjusted hazard ratio (aHR) for endometriosis in women with uterine leiomyoma was 6.44 (95% CI, 6.18, 6.72) compared with controls. The risk of endometriosis was significantly increased in women with uterine leiomyoma and comorbidities of tube-ovarian infection (aHR 2.86; 95% CI, 1.28, 6.36), endometritis (1.14; 1.06, 1.24), infertility (1.26; 1.16, 1.37), or allergic diseases (1.11; 1.05, 1.17). Having both uterine leiomyoma and endometritis significantly increased the risk of endometriosis (aHR 6.73; 95% CI, 6.07, 7.45) versus having only uterine leiomyoma (6.61; 6.33, 6.91) or endometritis (1.49; 1.31, 1.69). Similarly, having both uterine leiomyoma and infertility significantly increased the risk of endometriosis (aHR 6.95; 95% CI, 6.21, 7.78) versus having only uterine leiomyoma (6.66; 6.38, 6.96) or infertility (1.78; 1.57, 2.02).

Conclusions

A diagnosis of uterine leiomyoma appears to increase the risk of endometriosis. Patients presenting with uterine fibroids should be encouraged to give informed consent for possible simultaneous surgical treatment of endometriosis.

A prospective cohort study of ambient air pollution exposure and risk of uterine leiomyomata

STUDY QUESTION

To what extent are ambient concentrations of particulate matter <2.5 microns (PM2.5), nitrogen dioxide (NO2) and ozone (O3) associated with risk of self-reported physician-diagnosed uterine leiomyomata (UL)?

SUMMARY ANSWER

In this large prospective cohort study of Black women, ambient concentrations of O3, but not PM2.5 or NO2, were associated with increased risk of UL.

WHAT IS KNOWN ALREADY

UL are benign tumors of the myometrium that are the leading cause of gynecologic inpatient care among reproductive-aged women. Black women are clinically diagnosed at two to three times the rate of white women and tend to exhibit earlier onset and more severe disease. Two epidemiologic studies have found positive associations between air pollution exposure and UL risk, but neither included large numbers of Black women.

STUDY DESIGN, SIZE, DURATION

We conducted a prospective cohort study of 21 998 premenopausal Black women residing in 56 US metropolitan areas from 1997 to 2011.

PARTICIPANTS/MATERIAL, SETTING, METHODS

Women reported incident UL diagnosis and method of confirmation (i.e. ultrasound, surgery) on biennial follow-up questionnaires. We modeled annual residential concentrations of PM2.5, NO2 and O3 throughout the study period. We used Cox proportional hazards regression models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for a one-interquartile range (IQR) increase in air pollutant concentrations, adjusting for confounders and co-pollutants.

MAIN RESULTS AND THE ROLE OF CHANCE

During 196 685 person-years of follow-up, 6238 participants (28.4%) reported physician-diagnosed UL confirmed by ultrasound or surgery. Although concentrations of PM2.5 and NO2 were not appreciably associated with UL (HRs for a one-IQR increase: 1.01 (95% CI: 0.93, 1.10) and 1.05 (95% CI: 0.95, 1.16), respectively), O3 concentrations were associated with increased UL risk (HR for a one-IQR increase: 1.19, 95% CI: 1.07, 1.32). The association was stronger among women age <35 years (HR: 1.26, 95% CI: 0.98, 1.62) and parous women (HR: 1.28, 95% CI: 1.11, 1.48).

LIMITATIONS, REASONS FOR CAUTION

Our measurement of air pollution is subject to misclassification, as monitoring data are not equally spatially distributed and we did not account for time-activity patterns. Our outcome measure was based on self-report of a physician diagnosis, likely resulting in under-ascertainment of UL. Although we controlled for several individual- and neighborhood-level confounding variables, residual confounding remains a possibility.

WIDER IMPLICATIONS OF THE FINDINGS

Inequitable burden of air pollution exposure has important implications for racial health disparities, and may be related to disparities in UL. Our results emphasize the need for additional research focused on environmental causes of UL.

Management of Symptomatic Uterine Leiomyomas: ACOG Practice Bulletin, Number 228

Uterine leiomyomas (fibroids) are the most common solid and symptomatic neoplasm in women. They are the leading indication for hysterectomy (1, 2), which is a definitive and effective surgical treatment for leiomyoma. However, many patients benefit from and seek out management options other than hysterectomy because they desire future childbearing or wish to retain their uterus. The purpose of this Practice Bulletin is to provide updated evidence-based recommendations for the medical, procedural, and surgical management of symptomatic leiomyomas. Discussion of the use of morcellation in the surgical management of leiomyomas is beyond the scope of this document and is addressed in a separate American College of Obstetricians and Gynecologists (ACOG) publication (3).

Safety and efficacy of elagolix (with and without add-back therapy) for the treatment of heavy menstrual bleeding associated with uterine leiomyomas: a systematic review and meta-analysis

Background

Heavy menstrual bleeding (HMB) is a common clinical finding in patients with uterine leiomyomas that can negatively impact their quality of life. Recently, a novel oral GnRH-antagonist (elagolix) has emerged as a possible therapeutic agent for this ailment. Herein data was pooled from clinical trials assessing the safety and efficacy of elagolix with and without add-back therapy.

Main text

PubMed and Cochrane library were systematically searched for RCTs that measured the efficacy and safety of elagolix for the treatment of uterine fibroid-associated HMB. All safety and efficacy endpoints were compared between elagolix-alone, elagolix w/add-back therapy, and placebo. The primary efficacy endpoint was defined as the number of women who achieved menstrual blood loss (MBL) < 80 ml and a reduction in MBL from baseline of > 50% at the end of treatment. Secondary outcomes assessed included change in hemoglobin levels, incidence suppression of bleeding and amenorrhea, and the incidence of adverse events. The random effects model was used to pool data, and heterogeneity was assessed using I2.

Our search identified 4 clinical trials meeting our PICO criteria, with a total of 916 patients. Analysis of the primary outcome revealed that elagolix-alone was the most effective treatment compared to both placebo (LOR = 3.47, CI = 3.03–3.91, p = 0.000, I2 = 0.0%) and add-back therapy (LOR = 0.64, CI = 0.12–1.16, p = 0.016, I2 = 43.1%). Furthermore, both elagolix groups (irrespective of add-back therapy) observed a significant improvement in post-treatment hemoglobin levels as compared to the placebo group (elagolix-alone vs PBO: LOR = 1.44, CI = 0.66–2.22, I2 = 66.0%, p = 0.000; elagolix-w/add-back therapy vs PBO: LOR = 1.22, CI = 0.78–1.66, I2 = 0.0%, p = 0.000). Concerning safety, while elagolix without add-back therapy had the highest overall incidence of adverse effects (elagolix-alone vs placebo LOR = 0.84, CI = 0.48–1.20, I2 = 7.8%, p = 0.000; elagolix-alone vs elagolix-w/add-back LOR = 0.68, CI = 0.09–1.26, p = 0.024, I2 = 64.6%), the incidence of serious (life threatening) adverse events between all 3 treatment groups was not statistically different. The inclusion of add-back therapy with elagolix made the treatment noticeably safer (elagolix-w/add-back vs placebo: LOR = 0.19, CI = − 0.10 to 0.48, I2 = 0.0%, p = 0.194) without seriously compromising its efficacy.

Conclusion

High-quality evidence from 4 trials suggests that elagolix is an effective treatment for leiomyoma-associated HMB, with a marked improvement in all efficacy endpoints. Furthermore, the inclusion of add-back therapy in the treatment regimen should be considered as it mitigates the hypoestrogenic effects of elagolix.

The health concerns related to hysterectomy among Taiwanese women with uterine fibroids- a mixed-methods study

This study aimed to assess health concerns after hysterectomy from different perspectives among Taiwanese women with uterine fibroids. A mixed-methods was used in this study. In a cross-sectional study, 95 patients completed a structured questionnaire (Health Concern Questionnaire-HCQ). Face-to-face interviews with 5 patients were implemented for the qualitative component from OBS-GYN outpatient departments at two hospitals in Northern Taiwan. Participants who met the following criteria, 20 years of age or older, conscious alert without mental disturbances were recruited to this study. Descriptive statistics were calculated for social demographic variables and HCQ. A content analysis was used to analyze the qualitative data. The mean age was 46.28 of 95 patients. Findings of the present study showed that the most health concerns among patients with UFs after hysterectomy are hysterectomy-related complications, follow by impacts on daily life, body image and female identity, and intimacy and sexual relations. The findings of qualitative interviews supported the above findings. In addition, the information needs of post-operative self-care were identify in this qualitative interviews. The results of this research study could help healthcare professionals to address women's health concerns and provide adequate care for Taiwanese women with uterine fibroids after hysterectomy.

Efficacy of ulipristal acetate in women with fibroid induced menorrhagia: A systematic review and meta-analysis

AIM

To evaluate the efficacy of UPA in women with fibroid induced menorrhagia.

METHODS

Embase, MEDLINE, CAB Abstracts, Cochrane Central Register of Controlled Trials, PsychInfo were searched up to 18th May 2020 and updated on 7th February 2021. Randomised controlled trials evaluating the efficacy of UPA in women with fibroid induced menorrhagia were included in the study.

RESULTS

Two authors independently reviewed and extracted the study data. Statistical heterogeneity was quantified using I² statistics. Publication bias and data asymmetry was assessed by funnel plots. A meta-analysis was conducted where appropriate. Six studies were eligible for inclusion. UPA (5 mg and 10 mg) achieved statistically significant amenorrhoeic outcome when compared to placebo (p<0.00001). Increased adverse events (AE) profile was observed in the higher UPA dose, however, did not reach statistical significance.

CONCLUSIONS

This review demonstrates the efficacy of UPA in achieving amenorrhoea in women with fibroid induced menorrhagia. However, the favourable dose of UPA remains inconclusive when AE profile is taken into account. Evidence remains obscure regarding liver damage and further research is warranted to attain a conclusive outcome.

Therapeutic approach of uterine leiomyoma; choosing the most appropriate surgical option

The most common benign pelvic tumor in young women is uterine leiomyoma. It is often asymptomatic, but can cause symptoms such as pelvic-abdominal pain, vaginal bleeding, urinary and intestinal transit disorders. If there is a suspicion of malignancy, it is necessary to perform fractional uterine curettage to establish the histopathological diagnosis.The surgical treatment of uterine leiomyoma includes several procedures: myomectomy, subtotal or total hysterectomy. The procedure will be chosen depending on the patient's particularities: BMI, uterine size, leiomyoma location, surgical history or other associated pathologies.Laparoscopic hysterectomy has a 45-minute shorter duration of intervention than vaginal hysterectomy, and the conversion rate to the open procedure is lower.Laparoscopically treated cases have fewer postoperative complications compared to other surgical procedures and have a shorter hospitalization and recovery time.The recurrence rate of uterine leiomyoma is similar for both laparoscopic and open abdominal approach, and the frequency of long-term complications such as adhesion syndrome or pelvic pain is higher after the latter.

A Systematic Review of the Treatment of Uterine Myomas Using Transcervical Ultrasound-Guided Radiofrequency Ablation with the Sonata System

OBJECTIVE

To evaluate the treatment success, possible side effects, and safety of radiofrequency ablation with the Sonata System.

DATA SOURCES

An electronic literature search in the PubMed and Medline databases was carried out from inception to August 2020.

METHODS OF STUDY SELECTION

The review was performed in accordance with the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Keywords such as "Sonata," "transcervical ablation," and "uterine myoma" were used to identify all relevant articles independently by both authors. Full-text articles in English that reported at least 1 of the following outcomes were included in the study: reduction in perfused/total myoma volume, effect of treatment on bleeding intensity and myoma-related symptoms, number of surgical reinterventions, adverse events, return to activities of daily life, effects on surrounding tissue, and safety during pregnancy.

TABULATION, INTEGRATION, AND RESULTS

10 studies matching the inclusion criteria were identified and used for further analysis. A reduction in total and perfused myoma volume of 63.2% and 64.5% was achieved. One of the studies showed a 53.8 ± 50.5% (n = 48) reduction in Menstrual Pictogram Score, and another study showed a 51.1 ± 40.9% (n = 142) reduction in Pictorial Blood Loss Assessment Chart at 12 months. 87.2% (n = 190) of the patients reported a clinically meaningful reduction in menstrual blood loss after 12 months. While Symptom Severity Scores dropped by 28.8 ± 19.3, 23.3 ± 23.7, and 23.7 ± 19.4 points at 3, 6, and 12 months, respectively, Health-Related Quality of Life Scores increased to 77.5 ± 22.0, 82.8 ± 19.0, and 83.3 ± 20.5 points. One study had an 8% reintervention rate after 12 months, and another study showed a 0.7% and 5.2% rate after 12 and 24 months. After an average of 64 months after ablation, the reintervention rate was 11.8%. Time to return to activities of daily life was 2.9 ± 2.5 days. No related complications during pregnancy and delivery were reported.

CONCLUSION

Radiofrequency ablation with the Sonata System represents a minimally invasive, organ-preserving treatment option in patients with symptomatic uterine myomas, associated with clinically meaningful improvement of myoma-related symptoms.

Transcervical Radiofrequency Ablation of Uterine Fibroids Global Registry (SAGE): Study Protocol and Preliminary Results

Background

Transcervical fibroid ablation (TFA) is a minimally invasive, effective treatment of symptomatic uterine fibroids that utilizes intrauterine ultrasound for imaging and radiofrequency energy for ablation. Outcomes reported with TFA have been positive, with significant reductions in fibroid volume, improvements in symptom severity and health-related quality of life, and low complication and surgical reintervention rates. The SAGE registry characterizes the long-term (5-year) outcomes of TFA when used to treat symptomatic uterine fibroids in real-world usage.

Methods/Design

SAGE is an ongoing postmarket global registry involving up to 50 sites and up to 500 women who select TFA with the Sonata system for treatment of symptomatic uterine fibroids. Patients are followed for 5 years. Main outcomes include symptom severity score and health-related quality of life subscales of the UFS-QoL, general health status on the EQ-5D, perceived treatment benefit, treatment satisfaction, work and activity patterns, overall patient treatment outcome, adverse events, pregnancy incidence and outcomes, and surgical reinterventions for heavy menstrual bleeding.

Discussion

The SAGE registry represents the largest known study of TFA for uterine fibroids and will generate up to 2500 patient-years of outcome data. Preliminary results from the first 160 treated women suggest broad applicability of TFA to a wide range of fibroid types and sizes and an excellent safety profile, with a device-related adverse event rate of 0.6% and a serious procedure-related adverse event rate of 0.6%. Of the 241 fibroids treated, 10% were submucous, 52% transmural, 28% intramural, and 10% subserous. Ablated fibroid diameters ranged from <1 cm to >10 cm, with 27% of fibroids having maximum diameters >5 cm. The real-world experience from SAGE will strengthen the existing evidence on the durability of TFA in providing meaningful relief from uterine fibroid symptoms and will have important clinical and economic implications for patients, physicians, and healthcare payers.

Multiparametric MR evaluation of uterine leiomyosarcoma and STUMP versus leiomyoma in symptomatic women planned for high frequency focussed ultrasound: accuracy of imaging parameters and interobserver agreement for identification of malignancy

OBJECTIVE

To assess accuracy of and interobserver agreement on multiparametric MR findings to distinguish uterine leiomyoma (LM) from uterine leiomyosarcoma (LMS) and soft tissue tumour of unknown malignant potential.

METHODS

Inclusion criteria: All females over 18 years with least one uterine mass measuring 5 cm or more in at least one of the three standard orthogonal dimensions on MR with histopathological confirmation of LM, LMS, or soft tissue tumour of unknown malignant potential (STUMP) in the 3 months following MR. Patients with LMS were drawn from a larger cohort being assessed for MR-guided focussed ultrasound (MRgFUS) suitability. Image evaluation: Assessed variables were: lesion margin, margin definition, T2 signal homogeneity, >50% of lesion with T2 signal brighter than myometrium, haemorrhage, restricted diffusion, contrast enhancement (CE), CE pattern, local lymphadenopathy and ascites.

RESULTS

32 LM, 10 LMS and 1 STUMP were evaluated. Ill-defined (p-value = 0.0003-0.0004) or irregular (p = 0.003-0.004) lesion margin, T2 hyperintensity >50% (p = 0.001-0.004), and peripheral CE (p = 0.02-0.05) were significantly more common in LMS/STUMP than LM for both radiologists. 10/11 (Reader 2) and 11/11 (Reader 1) LMS/STUMP displayed restricted diffusion but so did 63-80% of LM. Agreement was greatest for margin characteristics (κ = 0.73-0.81).

CONCLUSION

Irregular/ill-defined lesion margin best distinguished LMS/STUMP from LM with good interrater reliability.

ADVANCES IN KNOWLEDGE

Assessment of agreement regarding MR parameters distinguishing LM from LMS and STUMP has not previously been undertaken in a cohort including a large number of patients with LMS. This will help inform evaluation of females considering minimally invasive LM treatment.

Treatment of Uterine Fibroid Symptoms with Relugolix Combination Therapy

BACKGROUND

Uterine fibroids are a common cause of heavy menstrual bleeding and pain. Treatment with the combination of relugolix (an oral gonadotropin-releasing hormone-receptor antagonist), estradiol, and norethindrone acetate, administered once daily, may have efficacy in women with uterine fibroids and heavy bleeding while avoiding hypoestrogenic effects.

METHODS

We conducted two replicate international, double-blind, 24-week, phase 3 trials involving women with fibroid-associated heavy menstrual bleeding. Participants were randomly assigned in a 1:1:1 ratio to receive once-daily placebo, relugolix combination therapy (40 mg of relugolix, 1 mg of estradiol, and 0.5 mg of norethindrone acetate), or delayed relugolix combination therapy (40 mg of relugolix monotherapy, followed by relugolix combination therapy, each for 12 weeks). The primary efficacy end point in each trial was the percentage of participants with a response (volume of menstrual blood loss <80 ml and a ≥50% reduction in volume from baseline) in the relugolix combination therapy group, as compared with the placebo group. Key secondary end points were amenorrhea, volume of menstrual blood loss, distress from bleeding and pelvic discomfort, anemia, pain, fibroid volume, and uterine volume. Safety and bone mineral density were assessed.

RESULTS

A total of 388 women in trial L1 and 382 in trial L2 underwent randomization. A total of 73% of the participants in the relugolix combination therapy group in trial L1 and 71% of those in trial L2 had a response (primary end point), as compared with 19% and 15%, respectively, of those in the placebo groups (P<0.001 for both comparisons). Both relugolix combination therapy groups had significant improvements, as compared with the placebo groups, in six of seven key secondary end points, including measures of menstrual blood loss (including amenorrhea), pain, distress from bleeding and pelvic discomfort, anemia, and uterine volume, but not fibroid volume. The incidence of adverse events was similar with relugolix combination therapy and placebo. Bone mineral density was similar with relugolix combination therapy and placebo but decreased with relugolix monotherapy.

CONCLUSIONS

Once-daily relugolix combination therapy resulted in a significant reduction in menstrual bleeding, as compared with placebo, and preserved bone mineral density in women with uterine fibroids.

Evaluation of Biomarkers in Myoma Patients: A Prospective Study Investigating the Role of LDH, CA 125, and IGF-1 after Uterus-Preserving Surgical Therapy

OBJECTIVE

Myomas are one of the most common tumors of the lower abdomen in women. At present, sonography and clinical examination are the prevalent diagnostic standards for these tumors, and no biomarkers have been established yet. The primary aim of this study was to determine if the surgical removal of myomas leads to a drop of lactate dehydrogenase (LDH), CA 125, and/or insulin-like growth factor (IGF-1) and therefore if these parameters are suitable as potential biomarkers for the presence or recurrence of a myoma.

STUDY DESIGN

The blood levels of LDH, CA 125, and IGF-1 were determined in 83 patients (age 18-50) with a verified diagnosis of myomas and surgical therapy at 3 different timepoints: preoperative (T0), 2 days postoperative (T1), and 6 months postoperative (T2). Vaginal sonography was performed preoperatively and once again at 6 months postoperatively.

RESULTS

The median (Q1-Q3) LDH values dropped significantly postoperatively: 239 (217-266) U/L at T0 versus 217 (190-255) U/L at T1, p < 0.001. The median (Q1-Q3) IGF-1 values also dropped: 140.4 (118.6-179.0) ng/mL versus 112.4 (99.5-143.0), p < 0.001. By contrast, the CA 125 values rose slightly but not significantly. At 6 months (n = 34), the LDH values were not significantly different from either the preoperative or the immediate postoperative values. This was observed both in patients with and without a recurrence of myoma. In contrast, the median (Q1-Q3) IGF-1 level at T2 was significantly elevated both in patients with sonographic evidence of new myomas (129.0 [116.0-163.1] ng/mL, p = 0.023) and in patients with sonographic proof of no new myomas (161.0 [130.2-198.5] ng/mL, p < 0.001).

CONCLUSION

Both LDH and IGF-1 dropped significantly in the immediate postoperative days in women with myomas after uterus-preserving surgeries were performed. The postoperative concentration of IGF-1 was correlated with the evidence of new myomas and can be potentially used for further monitoring. Future studies should be able to confirm these results. This study concludes that myomas do influence LDH and IGF-1 and could possibly be suitable as biomarkers.
