Uterine Artery Embolization versus Myomectomy: Impact on Quality of Life—Results of the FUME (Fibroids of the Uterus: Myomectomy versus Embolization) Trial

Use of Uterine Artery Embolization for the Treatment of Uterine Fibroids: A Comparative Review of Major National Guidelines

OBJECTIVE

Fibroids cause significant morbidity, including anemia, pelvic pain, and infertility. It is imperative that healthcare providers are well-versed in the varying treatments available for fibroids. Specifically, uterine artery embolization (UAE) is a treatment that improves anemia, pelvic pain, and quality of life. The purpose of this article is to compare international guidelines on UAE to offer best practices to healthcare providers.

DATA SOURCES

Guidelines from the American College of Obstetrics and Gynecology, The Royal College of Obstetricians and Gynaecologists and the Royal College of Radiologists, National College of French Gynecologists and Obstetricians, The Royal Australian and New Zealand College of Obstetricians and Gynaecologists, the Society of Obstetricians and Gynaecologists of Canada, and the National Institute for Health and Care Excellence were reviewed alongside peer-reviewed PubMed articles.

METHOD OF STUDY SELECTION

A comparative review of major international guidelines was conducted to encompass potential geographical, cultural, and societal variances with UAE.

TABULATION, INTEGRATION, AND RESULTS

Review of data revealed guidelines agree with many constituents surrounding treatment of fibroids with UAE. Guidelines diverge regarding offering UAE for small fibroids, intracavitary/submucosal fibroids, and pedunculated serosal fibroids with variations on suggested imaging. Most agree that an experienced care team, including a gynecologist and interventional radiologist, should be included. Preoperative antibiotics and intrauterine device removal may be recommended. UAE for patients who desire fertility remains an option after counseling within most guidelines.

CONCLUSIONS

UAE is a safe, efficacious, and cost-effective alternative to hysterectomy and myomectomy. Including UAE as a treatment option during the patient counseling process is critical. Guidelines vary based on data interpretation and are based on clinical research and expert opinion. Due to mixed data and lack of randomized controlled trials, organizations differ when offering UAE to patients who wish to preserve fertility. It is vital to note emerging studies supporting the safety of UAE for subsequent pregnancy.

Polyethylene Glycol microspheres for uterine artery embolization for the treatment of symptomatic uterine fibroids

BACKGROUND

Uterine fibroids are prevalent benign pelvic tumors, often causing debilitating symptoms that impair quality of life. Uterine fibroid embolization (UFE) is a consolidated minimally invasive treatment option. The purpose of this study is to report our experience with polyethylene glycol microspheres (HydroPearl) in UFE for symptomatic patients.

METHODS

This single-center retrospective study evaluated 37 consecutive patients with symptomatic uterine fibroids referred to our institution since November 2016 to February 2020 for UFE with HydroPearl microspheres. All patients included completed a comprehensive pre-UFE clinical assessment and underwent a magnetic resonance imaging (MRI) pre- and post-procedure. Technical success, procedure-related complications, clinical outcomes, follow-up MRI findings, and patient satisfaction were evaluated.

RESULTS

A technical success rate of 97% with complete bilateral uterine artery embolization was achieved. Significant improvements were observed in menorrhagia, bulk-type symptoms, abdominal pain, and urinary dysfunctions after UFE. Post-procedural MRI assessments demonstrated reductions in uterine and dominant fibroid volumes, indicating successful devascularization. No immediate procedural complications were reported. Symptoms interfering with everyday activities significantly improved after the procedure. Patient satisfaction was high, with 89% expressing satisfaction with the treatment and 84% indicating purpose to repeat the procedure if necessary.

CONCLUSIONS

Uterine artery embolization with HydroPearl is a safe and effective treatment option for symptomatic uterine fibroids. A significant improvement in menorrhagia and bulk-type symptoms after the procedure was observed correlated by a reduction in diameters and volumes of both the uterus and the main fibroid in post-procedural MRI.

Insurance-Based Differences in Treatment Patterns for Uterine Fibroids

PURPOSE

The aim of this study was to examine whether Medicaid versus commercial insurance and reimbursement are associated with uterine artery embolization (UAE) utilization rates for uterine fibroid treatment.

METHODS

This retrospective (October 2015 to September 2023) study of women aged 30 to 59 years who underwent procedures for the treatment of uterine fibroids (hysterectomy, myomectomy, or UAE) was based on the Inovalon Insights dataset for those with Medicaid or commercial insurance. Differences in the receipt of UAE versus hysterectomy or myomectomy by insurance type and relative reimbursement were assessed using logistic regression controlling for patient characteristics and geographic differences in treatment patterns. For women with either hysterectomy or myomectomy, differences in the receipt of these procedures laparoscopically or not were assessed by insurance type and relative reimbursement controlling for patient characteristics and geographic differences in treatment patterns.

RESULTS

Medicaid compared with commercial insurance was associated with 38% higher odds of UAE (odds ratio [OR], 1.38; 95% confidence interval [CI], 1.34-1.42). States with higher Medicaid reimbursement for hysterectomy were associated with lower odds for UAE (OR, 0.95; 95% CI, 0.92-0.98). For women with hysterectomy or myomectomy, those with Medicaid versus commercial insurance had 20% lower odds (OR, 0.80; 95% CI, 0.79-0.82) of undergoing the procedure laparoscopically.

CONCLUSIONS

Women insured by Medicaid versus commercial insurance were more likely to undergo the less invasive UAE procedure. Conversely, Medicaid patients who underwent hysterectomy or myomectomy were less likely to undergo the procedure laparoscopically. Both results are consistent with the notion that insurance status may influence both physician referral patterns and treatment options available to patients.

Conservative Treatment of Uterine Myomas: A Network Meta-analysis Of Randomized Controlled Studies

OBJECTIVE

To comparatively evaluate the effectiveness of uterine artery embolization (UAE), high-intensity focused ultrasound (HIFU), radiofrequency ablation treatment (RFT), and laparoscopic/laparotomic surgery in the conservative treatment of uterine fibroids.

DATA SOURCES

The research was performed via electronic databases PubMed, Embase, and Cochrane Library, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards.

METHODS OF STUDY SELECTION

The network included 10 randomized trials between 2000 and 2024 and 1002 randomized subjects.

TABULATION, INTEGRATIONS, AND RESULTS

The network meta-analysis was conducted with subroutine netmeta on R. The risk of bias was assessed using the Revised Cochrane risk-of-bias tool for randomized trials. The surface under the cumulative ranking curve (SUCRA) was computed by Bayesian network meta-analysis. Incidences of reintervention per 100 person/year of follow-up were 4.13 (range, 0-19.4), 16.1 (6.2-32.8), 14.3 (0-15.1), and 6 (4.3-6.7) for myomectomy, UAE, HIFU, and RFT, respectively. The incidence rate ratios compared with myomectomy were 2.45 (95% confidence interval [CI], 1.38-4.37), 5.23 (95% CI, 1.59-17.3), and 4.59 (95% CI, 0.77-27.3; p = .09) for UAE, HIFU, and RFT, respectively. RTF had the highest (SUCRA, 1.25% and 3%) whereas myomectomy had the lowest risk of reintervention (SUCRA, 98% and 95%) or hysterectomy during follow-up (median, 12 months; range, 3-24). The risk of major complications was significantly lower after UAE (odds ratio, 0.38; 95% CI, 0.17-0.85) than myomectomy. The procedure with the lowest likelihood of major complications was HIFU (SUCRA, 81.5%). Finally, in the evaluation of QoL at follow-up visits, there were no differences between the treatments studied, although the model was highly heterogeneous and inconsistent.

CONCLUSION

In the analysis of randomized trials, surgical myomectomy carried the least risk of reintervention and subsequent hysterectomy during a relatively short follow-up period. HIFU was the method with the lowest risk of major complications.

Uterine Fibroid Embolization Survey in Canada: Challenges, Opportunities, and Differences in Practices Across the Country

Purpose: To assess the current practices surrounding Uterine Fibroid Embolization (UFE) in Canada. Methods: An online survey was sent to Canadian Association for Interventional Radiology (CAIR) members. It included questions on symptoms prompting UFE, patient awareness, investigation, UFE settings, the number of UFE procedures, and post-UFE care. The findings were discussed at CAIR's 2023 annual meeting by an expert panel. Results: Out of 792 surveys sent, 87 were filled (11%). Menorrhagia is the most common indication for UFE (87%). Women's awareness of UFE as a treatment option for fibroids is viewed as poor or average by 94% of our survey respondents. Most respondents see patients in clinics (92%) before the procedure and evaluate fibroids with MRI pre-UFE (76%). There is variability in care post-UFE, with 33% of procedures being performed as day surgery while 67% lead to overnight stay. For pain management, intravenous analgesia (including patient-controlled analgesia) is used in 76% (63/83) of cases while 19% (16/83) of respondents mentioned using epidural analgesia. Finally, there is an even split between embolic agent used; non-spherical polyvinyl alcohol (50%) and spherical particles (50%). Conclusion: Respondents believe patients in Canada still have limited awareness of UFE. Interventional radiologists are increasingly involved in the entire patient care trajectory, overseeing pre-and post-procedure care and hospitalizing patients. For pain management after UFE, it is observed that while epidural analgesia has been demonstrated more effective than alternatives, it is not widely used as the primary method.

Systematic review and meta-analysis of current evidence in uterine artery embolization vs myomectomy for symptomatic uterine fibroids

This review compares the efficacy of Uterine Artery Embolization (UAE) and Myomectomy (MYO) in managing symptomatic Uterine Fibroids (UFs) in women who do not want hysterectomy. A meta-analysis was performed on all available studies that evaluated the relative benefits and harms of MYO and UEA for the management of patients suffering from UFs. Outcomes evaluated reintervention, UFs scores for quality of life (QOL) and symptom severity, and other complications. To determine mean differences (MDs) or odds ratios (ORs) with 95% confidence intervals (CIs), a random or fixed-effects model was utilized. A meta-analysis of 13 studies (9 observational and 4 randomized controlled trials) was conducted. The results indicated that UAE had a higher reintervention rate (OR 1.84; 95% CI 1.62-2.10; P < 0.01; I2 = 39%), hysterectomy rate (OR 4.04; 95% CI 3.45-4.72; P < 0.01; I2 = 59%), and symptom-severity score (OR - 4.02; 95% CI 0.82, 7.22; P = 0.01; I2 = 0%) compared to MYO at a four-year follow-up. However, UAE was associated with a lower rate of early complications (OR 0.44; 95% CI 0.20-0.95; P = 0.04; I2 = 25%), and readmission rate (OR 1.16; 95% CI 1.01-1.33; P = 0.04; I2 = 0%) compared to MYO. Furthermore, both procedures had comparable improvement in pregnancy rates and abnormal uterine bleeding. In conclusion, UAE and MYO are effective in treating symptomatic UFs but they have different outcomes. The decision on which procedure to choose should be made based on individual preferences and the physician's expertise.

Uterine artery embolization vs myomectomy for the management of women with uterine leiomyomas: a systematic review and meta-analysis

OBJECTIVE

This study aimed to investigate whether uterine artery embolization offers a better quality of life than myomectomy in premenopausal women diagnosed with leiomyomas of the uterus.

DATA SOURCES

A literature search was performed using the electronic databases of PubMed and Cochrane Central Register of Controlled Trials from inception to January 2023.

STUDY ELIGIBILITY CRITERIA

Randomized controlled trials comparing uterine artery embolization with myomectomy in women of premenopausal age suffering from uterine leiomyomas were considered.

METHODS

The primary outcome was quality of life. The secondary outcomes were reintervention rate and timing, successful pregnancy, stillbirth and miscarriage, cesarean delivery on delivery, and perioperative morbidity. Moreover, time-to-event and standard pairwise meta-analyses were performed, as appropriate. The certainty of the evidence was assessed in line with the Grading of Recommendations, Assessment, Development, and Evaluations methodology.

RESULTS

A total of 6 randomized controlled trials met our inclusion criteria. The meta-analysis suggested little to no difference in terms of quality of life between uterine artery embolization and myomectomy (standard mean difference, 0.05; 95% confidence interval, -0.38 to 0.48; I2=92%; very low certainty of evidence). Sensitivity analysis, including randomized controlled trials, which included solely myomectomy procedures in the control arm, demonstrated better quality of life for women treated with myomectomy (standard mean difference, -0.32; 95% confidence interval, -0.49 to -0.15; I2=15%). Concerning reintervention, myomectomy was likely associated with a decreased risk of future reintervention (risk ratio, 0.32; 95% confidence interval, 0.15-0.69; I2=60%; low certainty of evidence) and a more prolonged time interval since a potential reintervention because of recurrence than uterine artery embolization (hazard ratio, 0.41; 95% confidence interval, 0.22-0.77; I2=77%; low certainty of evidence). No difference was found between the 2 interventions concerning severe perioperative adverse events (relative risk, 4.13; 95% confidence interval, 0.44-39.20; I2=0%; low certainty of evidence).

CONCLUSION

Uterine artery embolization is likely associated with increased reintervention rates and less time to reintervention compared with myomectomy in premenopausal women diagnosed with uterine leiomyomas. Evidence suggests no difference between the 2 interventions regarding perioperative morbidity. Uterine artery embolization may exert no effect on quality of life and successful pregnancy; however, the evidence is very uncertain.

Uterine artery embolization versus myomectomy: a systematic review and meta-analysis

Introduction

Uterine fibroids are the commonest benign tumors of the reproductive tract in women of childbearing age. They are usually asymptomatic but can cause menorrhagia. Treatments include myomectomy and uterine artery embolization (UAE). The latter is a relatively new procedure, therefore of special interest.

Objectives

We conducted a systematic review and meta-analysis of all published studies to provide a comprehensive outlook on the effectiveness of UAE by comparing its outcomes to those of myomectomy. Electronic databases (PubMed and Cochrane Central) were systematically searched from January 2000 to March 2022 for published randomized control trials, observational studies, and meta-analyses that compared UAE to myomectomy for at least one of the pre-specified outcomes, namely re-intervention rates, length of hospital stay, and complications.

Methods

We shortlisted nine studies for the final analysis. For continuous outcomes, results from random-effects meta-analysis were presented as mean differences (MDs) and corresponding 95% confidence intervals (CIs). Risk ratios (RRs) for dichotomous outcomes were pooled using a random-effects model.

Results

The final analysis consisted of nine studies. Factors like re-intervention, hospitalization, and complications, each with its unique follow-up duration were assessed. Pooled analysis demonstrated significant results for greater re-intervention rates with UAE as compared to myomectomy (RR: 2.16, 95% CI: (1.27-3.66), p-value 0.004, heterogeneity I2 = 85%). UAE holds a greater but statistically insignificant risk for major complications (RR: 0.62, 95% CI: (0.29-1.33), p-value 0.22, heterogeneity I2 = 0%) and myomectomy shows a statistically insignificant greater risk for minor complications (RR: 1.72, 95% CI: (0.92-3.22), p-value 0.09, heterogeneity I2 = 0%). UAE had a shorter but statistically insignificant duration of hospital stay (MD: -1.12, 95% CI: (-2.50 to 0.27), p-value 0.11, heterogeneity I2 = 96%) (p-value for subgroup differences = 0.005).

Conclusion

Our meta-analysis of approximately 196,595 patients demonstrates that myomectomy results in a significant reduction in re-intervention rate compared to UAE.

True Costs of Uterine Artery Embolization: Time-Driven Activity-Based Costing in Interventional Radiology Over a 3-Year Period

PURPOSE

The aim of this study is to uncover potential areas for cost savings in uterine artery embolization (UAE) using time-driven activity-based costing, the most accurate costing methodology for direct health care system costs.

METHODS

One hundred twenty-three patients who underwent outpatient UAE for fibroids or adenomyosis between January 2020 and December 2022 were retrospectively reviewed. Utilization times were captured from electronic health record time stamps and staff interviews using validated techniques. Capacity cost rates were estimated using institutional data and manufacturer proxy prices. Costs were calculated using time-driven activity-based costing for personnel, equipment, and consumables. Differences in time utilization and costs between procedures by an interventional radiology attending physician only versus an interventional radiology attending physician and trainee were additionally performed.

RESULTS

The mean total cost of UAE was $4,267 ± $1,770, the greatest contributor being consumables (51%; $2,162 ± $811), followed by personnel (33%; $1,388 ± $340) and equipment (7%; $309 ± $96). Embolic agents accounted for the greatest proportion of consumable costs, accounting for 51% ($1,273 ± $789), followed by vascular devices (15%; $630 ± $143). The cost of embolic agents was highly variable, driven mainly by the number of vials (range 1-19) of tris-acryl gelatin particles used. Interventional radiology attending physician only cases had significantly lower personnel costs ($1,091 versus $1,425, P = .007) and equipment costs ($268 versus $317, P = .007) compared with interventional radiology attending physician and trainee cases, although there was no significant difference in mean overall costs ($3,640 versus $4,386; P = .061).

CONCLUSIONS

Consumables accounted for the majority of total cost of UAE, driven by the cost of embolic agents and vascular devices.

In vivo revascularization and tissue effects of uterine artery embolization with starch microspheres in sheep

OBJECTIVE

In uterine artery embolization (UAE) for the treatment of fibroids, nondegradable particles permanently occlude the uterine artery (UA). These particles remain in the vessels and can cause secondary undesirable effects, such as severe pain after embolization and fertility issues. In this prospective experimental study, we aimed to evaluate the angiographic recanalization, local and systemic reactions, and uterine damage occurring after performing UAE with newly developed degradable starch microspheres (DSMs) in sheep.

MATERIALS AND METHODS

Under general anesthesia, eight nonpregnant sheep underwent bilateral UAE using DSMs to achieve stasis. Angiographic evaluation was performed on days 1, 3 and 7 after embolization to assess in vivo recanalization. In addition, the angiographic series were scored via a modified embolization score. A postmortem tissue examination was performed to determine whether DSMs and foreign body inflammatory reactions were present and to assess uterine necrosis.

RESULTS

Complete bilateral embolization of the UA and cervicovaginal branches was achieved in all treated animals. Recanalization of the occluded arteries was evident in 25 of 27 arteries during the angiographic evaluation. In all sheep, there were multifocal areas of uterine necrosis, and some uterine vessels contained intraluminal material consistent with DSMs. The average weight of both uterine horns was significantly correlated with both the number of microspheres needed for complete embolization (r = 0.69, ρ<0.01) and the average percentage of necrosis in both uterine horns (r = 0.64, ρ<0.05).

CONCLUSIONS

Our findings demonstrated the efficacy of vascular embolization with DSM by inducing ischemic changes in the uterus and subsequent recanalization of previously occluded arteries.

The Effect of a Myomectomy on Myoma-related Symptoms and Quality of Life: A Retrospective Cohort Study

STUDY OBJECTIVE

Although it is assumed that myomectomy improves uterine myoma-related symptoms such as pelvic pain and heavy menstrual bleeding (HMB), validated measures are rarely reported. This study aimed to verify the effect of myomectomy on myoma-related symptoms.

DESIGN

A retrospective cohort study.

SETTING

A university-affiliated hospital.

PATIENTS

Our study included 241 patients with a myoma diagnosis and received a myomectomy between 2004 and 2018. Data were collected from the patient medical file and patients responded in 1 questionnaire.

INTERVENTIONS

Transcervical resection of myoma (TCRM) and laparoscopic or abdominal myomectomy (LAM).

MEASUREMENTS AND MAIN RESULTS

One year after TCRM, a significant number of women experienced symptom improvement for pelvic pain (79% [19/24, p = .01]) and HMB (89% [46/52, p <.001]). For other myoma-related symptoms, abdominal pressure (43%, 10/23), sexual complaints (67%, 2/3), infertility (56%, 10/18), and other complaints (83%, 5/6), improvements were not statistically significant. One year after LAM, a significant number of women experienced symptom improvement for pelvic pain (80%, 74/93), HMB (83%, 94/113), abdominal pressure (85%, 79/93), sexual complaints (77%, 36/47), and other complaints (91%, 40/44). One year after myomectomy, 47% (30/64) (TCRM) and 44% of women (78/177) (LAM) described no myoma-related symptoms. Most women (82% [172/217]) were satisfied with the postoperative result after 1 year and 53% (114/217) would have liked to receive the myomectomy earlier in life. Average quality of life (measured on a 10-point Likert scale) increased from 6.3 at baseline to 8.0 at 1 year after TCRM and from 6.2 to 8.0 1 year after LAM, resulting in a difference of 1.7 points (p <.001; 95% confidence interval, 1.1-2.3) and 1.9 points (p <.001; 95% confidence interval, 1.4-2.3), respectively.

CONCLUSION

One year after myomectomy, most women have benefited from myomectomy, concluded by a significant number of women who experienced myoma-related symptom improvement, positive patient satisfaction, and a significant improvement in reported quality of life. Validation of results after conventional treatment such as myomectomy is essential in counseling patients for surgical treatment in today's evidence based practice. In addition, it is necessary to make an adequate comparison with new treatment options for myomas. To provide this, further research should preferably be conducted prospectively or by randomization.

Management of women with abnormal uterine bleeding: Clinical practice guidelines of the French National College of Gynaecologists and Obstetricians (CNGOF)

OBJECTIVE

To provide French guidelines for the management of women with abnormal uterine bleeding (AUB).

DESIGN

A consensus committee of 26 experts was formed. A formal conflict-of-interest policy was developed at the beginning of the process and enforced throughout. The entire guidelines process was conducted independently of any industry funding (i.e. pharmaceutical or medical device companies). The authors were advised to follow the rules of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized.

METHODS

The last guidelines from the Collège National des Gynécologues et Obstétriciens Français on the management of women with AUB were published in 2008. The literature seems now sufficient for an update. The committee studied questions within 7 fields (diagnosis; adolescents; idiopathic AUB; endometrial hyperplasia and polyps; type 0-2 fibroids; type 3 or higher fibroids; and adenomyosis). Each question was formulated in a PICO (Patients, Intervention, Comparison, Outcome) format and evidence profiles were compiled. The GRADE® methodology was applied to the literature review and the formulation of recommendations.

RESULTS

The experts' synthesis work and the application of the GRADE method resulted in 36 recommendations. Among the formalized recommendations, 19 are strong and 17 weak. No response was found in the literature for 14 questions. We chose to abstain from recommendations rather than providing advice based solely on expert clinical experience.

CONCLUSIONS

The 36 recommendations make it possible to specify the diagnostic and therapeutic strategies for various clinical situations practitioners encounter, from the simplest to the most complex.

Care Delivery for Patients with Leiomyomas: Failures, Real-Life Experiences, Analysis of Barriers, and Proposed Restorative Remedies

In this narrative review, we describe historical and contemporary influences that prevent patients with fibroids from getting appropriate medical care. Using patient stories as examples, we highlight how misogyny on all levels hurts patients and prevents medical teams from doing their best. Importantly, inequity and disparities result in massive gaps in care delivery. We suggest that we, as gynecologists and surgeons, must join public discourse on this topic to highlight the inadequacies of care delivery and the reasons behind it, suggest potential solutions, and join patients and communities in formulating and implementing remedies.

Therapeutic options for the management of abnormal uterine bleeding

Just as the investigation of abnormal uterine bleeding (AUB) is approached systematically using the two FIGO systems for AUB in the reproductive years, treatment options can be considered similarly. Therapeutic options fall into two categories-medical and surgical-and while medical management is typically regarded as first-line therapy, there are several exceptions defined by the presenting cause or causes, mainly when infertility is a concurrent issue. In the early 1990s, up to 60% of women underwent a hysterectomy for the symptom of heavy menstrual bleeding (HMB), but this figure has decreased. The number of women undergoing a hysterectomy for benign disorders continues to decline, along with an increase in hysterectomies performed using minimally invasive techniques. Discussions about therapeutic options are tailored to the individual patient, and we include the risks and benefits of each option, including no management, to enable the patient to make an informed choice. The different types of treatment options and the factors affecting decision-making are considered in this article.

Public Awareness of Interventional Radiology: Population-Based Analysis of the Current State of and Pathways for Improvement

PURPOSE

To evaluate the awareness of interventional radiology (IR) among the public and identify methods for improvement.

MATERIALS AND METHODS

Participants (N = 1,000) were anonymously surveyed using Amazon's Mechanical Turk crowdsourcing platform about medical and IR-specific knowledge, preferred methods of acquisition of medical information, and suggestions for improving awareness of IR. The survey consisted of 69 questions, including both Likert Scale and free text questions.

RESULTS

Of the participants, 92% preferred undergoing a minimally invasive procedure over surgery. However, 39.8% recognized IR as a medical specialty, and less than 50% of these participants correctly identified IR as procedurally oriented. Of those who discussed or underwent an IR procedure (n = 113), most were also offered to undergo the procedure performed by a surgeon (n = 66). Furthermore, 71% (n = 20) of those who underwent the procedure performed by a surgeon reported that lack of awareness of IR played a role in their decision. Almost half of the respondents (n = 458) were interested in learning more about IR, particularly the diseases treated and procedures performed (42% and 37%, respectively). Short (<10-minute) educational videos and increased patient education by primary care providers (PCPs) were among the most suggested ways to improve awareness. Regarding the ambiguity of the name "interventional radiology," most respondents (n = 555) reported this to be true, and "minimally invasive radiologist" was the most preferred alternative (21.18%).

CONCLUSIONS

Lack of awareness of IR may underlie underutilization. When presented with the knowledge that IR improves patient outcomes, minimally invasive procedures by an interventional radiologist are more often desired by the public than surgical options. Educational videos and patient education by PCPs may increase awareness of IR.

Comparison of Recurrence and Quality of Life Between Myoma Embolization and Myomectomy

INTRODUCTION

Uterine myomas represent the most frequently diagnosed tumors among women of childbearing age. Symptoms often include profuse menstrual bleeding, diminished quality of life, and in some cases, infertility. The size and position of the fibroids typically influence the condition's manifestations. Moreover, symptomatology often varies depending on the fibroids' location. This investigation aimed to discern if there exists a significant correlation between life quality, reoccurrence rate, quality of life, and recurrence levels among patients who have undergone myomectomy and uterine fibroid embolization, respectively.

METHODOLOGY

A retrospective cross-sectional study was conducted to compare the rates of recurrence and impacts on life quality between uterine fibroid embolization and myomectomy in women diagnosed with uterine myomas. Data were collected from 152 women who sought treatment at the Obstetrics and Gynecology clinic and also the Interventional Radiology clinic between January 2009 and January 2021. Thirteen participants were excluded due to the inability to maintain contact. The trial encompassed 76 patients who underwent myomectomy and 63 who had uterine fibroid embolization. In both groups, the life quality of 50 patients, five years postsurgery, was assessed using the UFS-QOL measure. Eligible participants were females between 20 and 40 years, with symptomatic Type 3-5 fibroids as per the FIGO classification, and with no comorbidities. Individuals under 20 or over 40 years, or those with fibroids classified as FIGO types 1,2,6,7,8, were not included. Other exclusion criteria included pregnancy status, abnormal endometrial biopsy results, abnormal smear tests, polyps, cancer, adenomyosis and coagulation disorders.

RESULTS

The recurrence of fibroids was identified through symptomatology and diagnostic radiological methods. The recurrence rate was found to be 31.6% (n=24) for myomectomy patients and 14.3% (n=9) for those who underwent uterine fibroid embolization, with no statistically significant difference between the two groups (p > 0.05). The group subjected to myomectomy exhibited fewer symptoms, lower anxiety, and better physical mood scores. The myomectomy group displayed higher average anxiety scores (p<0.01). There were no significant disparities in control, consciousness, sexual function, or overall scores between the two groups. Symptoms and anxiety saw a marked reduction in the first postoperative year compared to the preoperative period (p<0.01). Compared to presurgery, energy, mood, awareness, and sexual function exhibited significant improvements in the first and fifth postoperative years (p<0.01).

CONCLUSIONS

Our findings suggest a nonsignificant recurrence rate in the myomectomy group compared to the uterine artery embolization group. Notably, the decrease in symptom occurrence and anxiety following myomectomy was significantly favorable in terms of quality of life. While embolization was offered as a therapeutic option, myomectomy yielded more favorable results concerning quality of life.

Uterine-preserving treatments or hysterectomy reintervention after myomectomy or uterine artery embolisation: A retrospective cohort study of long-term outcomes

OBJECTIVE

To assess comparative rates of further uterine-preserving procedures (UPP) or hysterectomy reintervention, after myomectomy or uterine artery embolisation (UAE).

DESIGN

Population-based, retrospective cohort study.

SETTING

England.

POPULATION

Women who underwent myomectomy or UAE between 2010 and 2015 under the NHS.

METHODS

Data was abstracted from NHS Health Episode Statistics datasets. Hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated using Cox proportional-hazards regression.

MAIN OUTCOMES MEASURES

30-day readmission, UPP and hysterectomy reintervention rates.

RESULTS

9443 and 6224 women underwent elective myomectomy or UAE, respectively. After 118 136 total person-years of follow-up, the rate of hysterectomy was 8.34 and 20.98 per 1000 patient years for myomectomy or UAE, respectively. There was a 2.4-fold increased risk of undergoing hysterectomy after UAE when compared with myomectomy in adjusted models (HR 2.38 [95% CI 2.10-2.66]) [adjusted for age, ethnicity, multiple deprivation index, geographical region and comorbidities]. The HR for undergoing a UPP reintervention was 1.44 (95% CI 1.29-1.60) in favour of myomectomy. The rate of hysterectomy was increased 22% following UAE compared with laparoscopic myomectomy (0.97-1.52). Age may influence reintervention rates, and there was variation in hysterectomy risk when stratified by geographical region.

CONCLUSIONS

After a median of 7 years of follow-up, there is a 2.4-fold increased rate of hysterectomy and 44% increased risk of UPPs as reintervention after UAE, relative to myomectomy. These findings will aid pre-procedure counselling for women with fibroids. Future work should investigate the effect of other outcome modifiers, such as fertility intentions and fibroid anatomical characteristics.

An update on uterine artery embolization for uterine leiomyomata and adenomyosis of the uterus

Uterine artery embolization (UAE) is an established technique to treat benign diseases of the uterus such as uterine leiomyomata (fibroids) and adenomyosis. This article reviews the use of UAE in these conditions and summarizes the evidence regarding safety and efficacy of the technique based on the current literature.

Effects on heavy menstrual bleeding and pregnancy of uterine artery embolization (UAE) or myomectomy for women with uterine fibroids wishing to avoid hysterectomy: The FEMME randomized controlled trial

OBJECTIVE

To determine treatment options (myomectomy vs. uterine artery embolization (UAE)) for women wishing to avoid hysterectomy.

METHODS

A multicenter randomized controlled trial was conducted on 254 women and data were collected on fibroid-specific quality of life (UFS-QOL), loss of menstrual blood, and pregnancy.

RESULTS

At 4 years, the mean difference in the UFS-QOL was 5.0 points (95% confidence interval (CI) -1.4 to 11.5; P = 0.13) in favor of myomectomy. This was not statistically significant as it was at 2 years. There were no differences in bleeding scores, rates of amenorrhea, or heavy bleeding. Of those who were still menstruating, the majority reported regular or fairly regular periods: 36 of 48 (75%) in the UAE group and 30 of 39 (77%) in the myomectomy group. Twelve women after UAE and six women after myomectomy became pregnant (4 years) with seven and five live births, respectively (hazard ratio 0.48, 95% CI 0.18-1.28). There was no difference between the levels of hormones associated with the uterine reserve in each group.

CONCLUSION

Leiomyoma are common in reproductive-aged women, causing heavy menses and subfertility. Among women with uterine fibroids, myomectomy resulted in better fibroid-related quality of life at 4 years, compared with UAE but the treatments decreased menstrual bleeding equally. There was also no significant difference in the impact of treatment on ovarian reserve.

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.

Evidences in Uterine Artery Embolization: A Radiologist's Primer

Uterine artery embolization is an established minimally invasive therapy for symptomatic fibroids. It has also been used for other diseases of the uterus, including adenomyosis, uterine arteriovenous malformation, ectopic pregnancy, abnormal invasive placenta, and postpartum hemorrhage. In this review, we provide an updated and comprehensive review of uterine artery embolization based on the evidence published. We review the indications, the role of MRI, technical aspects, and complications of the procedure. The issues with a future pregnancy, risk of infertility, and fetal radiation are discussed as well.

Linzagolix with and without hormonal add-back therapy for the treatment of symptomatic uterine fibroids: two randomised, placebo-controlled, phase 3 trials

BACKGROUND

Uterine fibroids are common non-cancerous neoplasm that cause heavy menstrual bleeding and other signs. Linzagolix is an oral gonadotropin-releasing hormone receptor antagonist taken once per day that dose-dependently suppresses gonadal steroids and might reduce uterine-fibroid-associated signs. Two phase 3 trials were conducted to confirm the efficacy and safety of linzagolix at full-suppression (200 mg) and partial-suppression (100 mg) doses with or without hormonal add-back therapy (1 mg oestradiol and 0·5 mg norethisterone acetate) compared with placebo for the treatment of symptomatic uterine fibroids.

METHODS

PRIMROSE 1 and PRIMROSE 2 were identical 52-week, randomised, parallel, double-blind, placebo-controlled, phase 3 trials conducted at clinics in the USA (PRIMROSE 1) and Europe and the USA (PRIMROSE 2). Eligible women with uterine fibroid-associated heavy menstrual bleeding (menstrual blood loss >80 mL per cycle) were randomly assigned in a 1:1:1:1:1 ratio to one of five masked treatments: (1) placebo, (2) 100 mg linzagolix per day alone, (3) 100 mg linzagolix per day with once-per-day hormonal add-back therapy (1 mg oestradiol and 0·5 mg norethisterone acetate), (4) 200 mg linzagolix per day alone, or (5) 200 mg linzagolix per day with once-per-day hormonal add-back therapy (1 mg oestradiol and 0·5 mg norethisterone acetate). The primary endpoint was a response (menstrual blood loss ≤80 mL and ≥50% reduction from baseline) at 24 weeks in women who received at least one dose of treatment and did not meet any exclusion criteria based on predosing assessments. These trials are registered with ClinicalTrials.gov (NCT03070899 and NCT03070951). The trials have been completed.

FINDINGS

Between May, 2017, and October, 2020, in PRIMROSE 1, 574 women were enrolled, of which 48 discontinued and 15 were excluded; therefore, 511 women were included in the full analysis set; and in PRIMROSE 2, 535 women were enrolled, of which 24 did not receive the study drug and ten women were excluded from the study, resulting in 501 women being included in the full analysis set. In both trials, a significantly higher proportion of women had a reduction in heavy menstrual bleeding in all linzagolix (with or without add-back therapy) treatment groups compared with the placebo group (p≤0·003). In PRIMROSE 1, the response rates were 56·4% (95% CI 45·8-66·6%) in the 100 mg group, 66·4% (56·6-75·2%) in the 100 mg plus add-back therapy group, 71·4% (61·8-79·8%) in the 200 mg group, and 75·5% (66·0-83·5%) in the 200 mg plus add-back therapy group, compared with 35·0% (25·8-45·0%) in the placebo group. In PRIMROSE 2, the response rates were 56·7% (46·3-66·7%) in the 100 mg group, 77·2% (67·8-85·0%) in the 100 mg plus add-back therapy group, 77·7% (68·4-85·3%) in the 200 mg group, and 93·9% (87·1-97·7%) in the 200 mg plus add-back therapy group, compared with 29·4% (20·8-39·3%) with placebo. The most common adverse events up to 24 weeks were hot flushes (35% of participants in PRIMROSE 1 and 32% in PRIMROSE 2 with linzagolix [200 mg] alone and 3-14% in all other groups).

INTERPRETATION

Linzagolix (100 mg or 200 mg) with or without add-back therapy significantly reduced heavy menstrual bleeding. Partial suppression with once-per-day linzagolix (100 mg) without add-back therapy potentially provides a unique option for the chronic treatment of symptomatic uterine fibroids in women who cannot or do not want to take concomitant hormonal add-back therapy.

Meta-Study of the Clinical Effect of Conservative Treatment in Uterine Fibroids

Heavy menstrual bleeding (HMB), distress in the pelvis, infertile, and stressed feelings are all indications of fibroids in the uterus, the most prevalent type of benign uterine tumor. Nearly one-third of women with fibroid in the uterus seek medical help. The goal of this analysis is for a better understanding of the mechanisms that relate fibroids to these symptoms and to assess several treatment options, including the application of the gonadotropin-releasing hormone (GnRH) antagonist. We compiled the commonest as well as appropriate studies on the most common symptom of fibroids, as well as medicinal and surgical treatment options. Those who said they used GnRH antagonists orally were probed further. The underlying mechanisms myoma-caused menorrhagia as well as sterility were examined since those have been critical to understand the detailed mechanism as well as the targeted treatment modality. New treatments are determined by the amount, dimension cum localization of fibroids, and the women's age and also her choice on future childbirth. Myomas have considerable economic consequences with respect to direct expenditure, wage losses, as well as difficulties. In this context, medical, surgical, and nonsurgical techniques were examined. The novelty applied in this research article is the implementation of the GnRH antagonist-based methodology for the removal of fibroids in the uterine layer. The methodology is superior to the existing techniques for the treatment of fibroids in the uterine membrane. Novel medical techniques including GnRH antagonists were investigated and proved to be a viable new option. Alternatives to surgical-surgical modalities are desperately needed, specifically for those who are looking forward for future childbirth. GnRH antagonists have been shown to effectively alleviate the symptoms of fibroids and welcome new techniques for myoma treatment.

Current Strategies for Prevention of Infection After Uterine Artery Embolisation

Uterine artery embolisation (UAE) is a safe and effective procedure for symptomatic uterine fibroids with an estimated rate of post-operative intra-uterine infection of 0.9-2.5%. While rates of infection have remained low over the past two decades, there is variation in infection prevention practices. Intra-uterine infection after UAE may occur via access site haematogenous spread or ascension of vaginal flora through the cervical canal. Although the evidence base is immature, risk factors for infection including previous pelvic infection, hydrosalpinx, endocervical incompetence, diabetes, smoking, obesity, respiratory disease, and immunosuppression should be assessed during the pre-operative consultation with the interventional radiologist to tailor a plan for minimising infection, which may include optimisation of any modifiable risk facts and prophylactic antibiotics.

Magnetic resonance imaging parameter-based machine learning for prognosis prediction of high-intensity focused ultrasound ablation of uterine fibroids

Objectives: To develop and apply magnetic resonance imaging (MRI) parameter-based machine learning (ML) models to predict non-perfused volume (NPV) reduction and residual regrowth of uterine fibroids after high-intensity focused ultrasound (HIFU) ablation.Methods: MRI data of 573 uterine fibroids in 410 women who underwent HIFU ablation from the Chongqing Haifu Hospital (training set, N = 405) and the First Affiliated Hospital of Chongqing Medical University (testing set, N = 168) were retrospectively analyzed. Fourteen MRI parameters were screened for important predictors using the Boruta algorithm. Multiple ML models were constructed to predict NPV reduction and residual fibroid regrowth in a median of 203.0 (interquartile range: 122.5-367.5) days. Furthermore, optimal models were used to plot prognostic prediction curves.Results: Fourteen features, including postoperative NPV, indicated predictive ability for NPV reduction. Based on the 10-fold cross-validation, the best average performance of multilayer perceptron achieved with R² was 0.907. In the testing set, the best model was linear regression (R² =0.851). Ten features, including the maximum thickness of residual fibroids, revealed predictive power for residual fibroid regrowth. Random forest model achieved the best performance with an average area under the curve (AUC) of 0.904 (95% confidence interval (CI), 0.869-0.939), which was maintained in the testing set with an AUC of 0.891 (95% CI, 0.850-0.929).Conclusions: ML models based on MRI parameters can be used for prognostic prediction of uterine fibroids after HIFU ablation. They can potentially serve as a new method for learning more about ablated fibroids.

[Management of women with abnormal uterine bleeding: Clinical practice guidelines of the French National College of Gynecologists and Obstetricians (CNGOF)]

OBJECTIVE

To provide French guidelines for the management of women with abnormal uterine bleeding (AUB).

DESIGN

A consensus committee of 26 experts was formed. A formal conflict-of-interest (COI) policy was developed at the beginning of the process and enforced throughout. The entire guidelines process was conducted independently of any industrial funding (i.e. pharmaceutical, or medical devices). The authors were advised to follow the rules of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized.

METHODS

The last guidelines from the Collège national des gynécologues et obstétriciens français (CNGOF) on the management of women with AUB was published in 2008. The literature seems now sufficient for an update. The committee studied questions within 7 fields (diagnosis; adolescent; idiopathic AUB; endometrial hyperplasia and polyps; fibroids type 0 to 2; fibroids type 3 and more; adenomyosis). Each question was formulated in a PICO (Patients, Intervention, Comparison, Outcome) format and the evidence profiles were produced. The literature review and recommendations were made according to the GRADE® methodology.

RESULTS

The experts' synthesis work and the application of the GRADE method resulted in 36 recommendations. Among the formalized recommendations, 19 present a strong agreement and 17 a weak agreement. Fourteen questions did not find any response in the literature. We preferred to abstain from recommending instead of providing expert advice.

CONCLUSIONS

The 36 recommendations made it possible to specify the diagnostic and therapeutic strategies of various clinical situations managed by the practitioner, from the simplest to the most complex.

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.

Clinical outcomes of uterine artery embolization and experience of postoperative transvaginal fibroid expulsion: a retrospective analysis

PURPOSE

To explore the efficacy of uterine artery embolization (UAE) in the treatment of uterine fibroid and share the experience of transvaginal fibroid expulsion (FE) after UAE.

METHODS

We retrospectively analyzed the changes in uterine and fibroid volume in 152 patients with symptomatic uterine fibroid after UAE at Fujian Provincial Hospital and Fujian Longyan People Hospital from March 2014 to March 2020. After a 12-month follow-up, the improvement in postoperative clinical symptoms and the incidence of complications were evaluated. We also shared the clinical features and imaging findings of four patients with FE after UAE.

RESULTS

All 152 patients successfully underwent UAE. After a 12-month follow-up, the postoperative volumes of the uterus and fibroid at 3, 6, and 12 months were significantly reduced or disappeared compared to those before surgery (P < 0.05). Clinical symptoms, such as menorrhagia, dysmenorrhea, prolonged menstrual period, anemia, increased leucorrhea, pelvic discomfort, and urinary tract compression, were significantly improved after UAE. Among the 152 patients, the incidences of postoperative fever, nausea, vomiting, lower abdominal pain, and increased vaginal secretion were 7.89%, 7.24%, 3.95%, 19.08%, and 4.61%, respectively. Additionally, there were six cases of FE, with an incidence of 3.95%. Three cases of fibroid specimens and pathological images of fibroid biopsy, which were expelled through the vagina, were also provided.

CONCLUSION

UAE is a satisfactory alternative surgical method for symptomatic uterine fibroid with definitive efficacy and high safety. However, it is necessary to guard against the occurrence of postoperative complications such as FE.

Randomised Controlled Trial of Particles Used in Uterine fibRoid Embolisation (PURE): Non-Spherical Polyvinyl Alcohol Versus Calibrated Microspheres

Purpose

The PURE study is a randomised controlled trial (RCT) comparing the clinical and MRI outcomes of patients treated with non-spherical polyvinyl alcohol, ns-PVA (Contour PVA–Boston Scientific–355–500 & 500–700 microns) versus calibrated hydrogel microspheres (Embozene–Varian Inc–700 & 900 microns) for symptomatic uterine fibroids.

Materials and Methods

Prospective, ethically approved non-sponsored RCT in 84 patients in a single UK tertiary IR unit, ISRCTN registry trial number ISRCTN18191539 in 2013 and 2014. All patients with symptomatic fibroid disease were eligible. UAE followed a standardised protocol with UFS-QOL and contrast-enhanced MRI before and 6 months post UAE. Outcome measures included: (1) Uterine Fibroid Symptom and Quality of Life questionnaire (UFS-QOL). (2) Percentage total and dominant fibroid infarction. (3) Uterine and dominant fibroid volume reduction. (4) Volume of embolics.

Results

Sixty-three patients completed the QOL follow-up (33 ns-PVA vs 30 Embozenes), the groups were equivalent at baseline. Patients were followed up for 6 months following UAE. There was no significant difference in symptom scores or HR-QOL between ns-PVA and Embozenes, p = 0.67 and 0.21, respectively. 92.7% of patients treated with ns-PVA achieved > 90% dominant fibroid infarction versus 61.8% treated with Embozenes (p = 0.0016). 66% of patients treated with ns = PVA achieved > 90% total fibroid percentage infarction compared with 35% in the Embozene group (p = 0.011). The mean vials/syringes used were 5.2 with Embozenes versus 4.1 using PVA (p = 0.08).

Conclusion

The PURE study informs IRs regarding the efficacy of embolic agents in UAE, with superior fibroid infarction on MRI using ns-PVA versus Embozenes however no significant difference in clinical outcomes at 6 months after UAE.

Uterine artery embolization or myomectomy for women with uterine fibroids: Four-year follow-up of a randomised controlled trial

Objective

To examine the quality of life experienced by women with symptomatic uterine fibroids who had been treated with UAE in comparison to myomectomy. We report the four-year follow-up of the FEMME randomised trial. Two-year follow-up data has been previously reported.

Study Design

Premenopausal women who had symptomatic uterine fibroids amenable to myomectomy or uterine artery embolization were recruited from 29 UK hospitals. Women were excluded if they had significant adenomyosis, any malignancy, pelvic inflammatory disease or had had a previous open myomectomy or uterine artery embolization.

Participants were randomised to myomectomy or embolization in a 1:1 ratio using a minimisation algorithm. Myomectomy could be open abdominal, laparoscopic or hysteroscopic, according to clinician preference. Embolization of the uterine arteries was performed according to local practice, under fluoroscopic guidance.

The primary outcome measure was the Uterine Fibroid Symptom Quality of Life questionnaire, adjusted for baseline score and reported here at four years post-randomisation. Subsequent procedures for fibroids, pregnancy and outcome were amongst secondary outcomes.

Trial registration ISRCTN70772394 https://doi.org/10.1186/ISRCTN70772394

Results

254 women were randomized, 127 to myomectomy (105 underwent myomectomy) and 127 to uterine artery embolization (98 underwent embolization). At four years, 67 (53%) and 81 (64%) completed UFS-QoL quality of life scores. Mean difference in the UFS-QoL at 4 years was 5.0 points (95% CI −1.4 to 11.5; p = 0.13) in favour of myomectomy. There were 15 pregnancies in the UAE group and 7 in the myomectomy group, with a cumulative pregnancy rate to four years of 15% and 6% respectively (hazard ratio: 0.48; 95% CI 0.18–1.28). The cumulative repeat procedure rate to four years was 24% in the UAE group and 13% in the myomectomy group (hazard ratio: 0.53; 95% CI 0.27–1.05).

Conclusions

Myomectomy resulted in greater improvement in quality of life compared with uterine artery embolization, although by four years, this difference was not statistically significant. Missing data may limit the generalisability of this result. The numbers of women becoming pregnant were too small draw a conclusion on the effect of the procedures on fertility.

Comparison of (Cost-)Effectiveness of Magnetic Resonance Image-Guided High-Intensity-Focused Ultrasound With Standard (Minimally) Invasive Fibroid Treatments: Protocol for a Multicenter Randomized Controlled Trial (MYCHOICE)

BACKGROUND

Magnetic resonance image-guided high-intensity-focused ultrasound (MR-HIFU) is a rather new, noninvasive option for the treatment of uterine fibroids. It is safe, effective, and has a very short recovery time. However, a lack of prospectively collected data on long-term (cost-)effectiveness of the MR-HIFU treatment compared with standard uterine fibroid care prevents the MR-HIFU treatment from being reimbursed for this indication. Therefore, at this point, when conservative treatment for uterine fibroid symptoms has failed or is not accepted by patients, standard care includes the more invasive treatments hysterectomy, myomectomy, and uterine artery embolization (UAE). Primary outcomes of currently available data on MR-HIFU treatment often consist of technical outcomes, instead of patient-centered outcomes such as quality of life (QoL), and do not include the use of the latest equipment or most up-to-date treatment strategies. Moreover, data on cost-effectiveness are rare and seldom include data on a societal level such as productivity loss or use of painkillers. Because of the lack of reimbursement, broad clinical implementation has not taken place, nor is the proper role of MR-HIFU in uterine fibroid care sufficiently clear.

OBJECTIVE

The objective of our study is to determine the long-term (cost-)effectiveness of MR-HIFU compared with standard (minimally) invasive fibroid treatments.

METHODS

The MYCHOICE study is a national, multicenter, open randomized controlled trial with randomization in a 2:1 ratio to MR-HIFU or standard care including hysterectomy, myomectomy, and UAE. The sample size is 240 patients in total. Women are included when they are 18 years or older, in premenopausal stage, diagnosed with symptomatic uterine fibroids, conservative treatment has failed or is not accepted, and eligible for MR-HIFU. Primary outcomes of the study are QoL 24 months after treatment and costs of treatment including direct health care costs, loss of productivity, and patient costs.

RESULTS

Inclusion for the MYCHOICE study started in November 2020 and enrollment will continue until 2024. Data collection is expected to be completed in 2026.

CONCLUSIONS

By collecting data on the long-term (cost-)effectiveness of the MR-HIFU treatment in comparison to current standard fibroid care, we provide currently unavailable evidence about the proper place of MR-HIFU in the fibroid treatment spectrum. This will also facilitate reimbursement and inclusion of MR-HIFU in (inter)national uterine fibroid care guidelines.

Choice of primary and secondary outcomes in randomised controlled trials evaluating treatment for uterine fibroids: a systematic review

BACKGROUND

Core outcome sets aim to reduce research heterogeneity and standardise reporting, allowing meaningful comparisons between studies.

OBJECTIVES

To report on outcomes used in randomised controlled trials (RCTs) investigating uterine fibroid treatments, towards the development of a core outcome set for fibroid research.

SELECTION STRATEGY

Database search of MEDLINE, PubMed, EMBASE and CINAHL (inception to July 2021) for all English-language RCTs involving surgical or radiological fibroid treatments.

DATA COLLECTION AND ANALYSIS

A total of 1885 texts were screened for eligibility by two reviewers independently according to PRISMA methodology. JADAD and Management of Otitis Media with Effusion in Cleft Palate (MOMENT) scores were used to assess methodological and outcome reporting quality of studies, respectively. Outcomes were mapped to nine domains. Non-parametric tests for correlation and to compare group medians were undertaken.

MAIN RESULTS

There were 23 primary outcomes (23 outcome measures) and 173 secondary outcomes (95 outcome measures) reported in 60 RCTs (5699 participants). The domains with highest frequency of primary outcomes reported were bleeding and quality of life (QoL). The most frequent primary outcomes were postoperative pain, QoL and menstrual bleeding. No primary outcomes were mapped to fertility domains. Median MOMENT outcome score was 5 (interquartile range 3). There was correlation between MOMENT outcome score and JADAD scores (r = 0.491, P = 0.0001), publishing journal impact factor (r = 0.419, P = 0.008) and publication year (r = 0.332, P = 0.01).

CONCLUSION

There is substantial variation in the outcomes reported in fibroid RCTs. There is a need for a core outcome set for fibroid research, to allow improved understanding regarding the effects of different treatments.

Nonenhanced MRI-based radiomics model for preoperative prediction of nonperfused volume ratio for high-intensity focused ultrasound ablation of uterine leiomyomas

OBJECTIVES

To develop and assess nonenhanced MRI-based radiomics model for the preoperative prediction of nonperfused volume (NPV) ratio of uterine leiomyomas after high-intensity focused ultrasound (HIFU) treatment.

METHODS

Two hundred and five patients with uterine leiomyomas treated by HIFU were enrolled and allocated to training (N =164) and testing cohorts (N = 41). Pyradiomics was used to extract radiomics features from T2-weighted images and apparent diffusion coefficient (ADC) map generated from diffusion-weighted imaging (DWI). The clinico-radiological model, radiomics model, and radiomics-clinical model which combined the selected radiomics features and clinical parameters were used to predict technical outcomes determined by NPV ratios where three classification groups were created (NPV ratio ≤ 50%, 50-80% or ≥ 80%). The receiver operating characteristic (ROC) curve, area under the curve (AUC), and calibration and decision curve analyses were performed to illustrate the prediction performance and clinical usefulness of model in the training and testing cohorts.

RESULTS

The multi-parametric MRI-based radiomics model outperformed T2-weighted imaging (T2WI)-based radiomics model, which achieved an average AUC of 0.769 (95% confidence interval [CI], 0.701-0.842), and showed satisfactory prediction performance for NPV ratio classification. The radiomics-clinical model demonstrated best prediction performance for HIFU treatment outcome, with an average AUC of 0.802 (95% CI, 0.796-0.850) and an accuracy of 0.762 (95% CI, 0.698-0.815) in the testing cohort, compared to the clinico-radiological and radiomics models. The decision curve also indicated favorable clinical usefulness of the radiomics-clinical model.

CONCLUSIONS

Nonenhanced MRI-based radiomics has potential in the preoperative prediction of NPV ratio for HIFU ablation of uterine leiomyomas.

Uterine artery embolization, surgery and high intensity focused ultrasound in the treatment of uterine fibroids: a network meta-analysis

Background

To systematic review the safety and effectiveness between uterine artery embolization (UAE), surgery and high intensity focused ultrasound (HIFU) in the treatment of uterine fibroids.

Methods

The PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang Data, and CNKI were electronically searched to collect relevant studies on comparing the safety and effectiveness of UAE, surgery and HIFU in the treatment of uterine fibroids from January 2000 to August 2019. After two reviewers independently screened the literature, extracted the data and evaluated the risk of bias of included studies, network meta-analysis was performed by ADDIS 1.16.8 and Stata 14 software.

Results

A total of 11 studies (22 articles) involving 3,646 patients were included. Compared with surgery, UAE and HIFU patients had higher quality of life (1-year follow-up) improvement, and UAE was higher than HIFU. Network meta-analysis show that patients treated with HIFU had the lowest incidence of major complications within 1 year, followed by UAE, and the highest surgery. Patients treated with HIFU and UAE have shorter hospital stays and quicker recovery time than surgery. The rate of further intervention after surgery treatment might be lower than that of UAE and HIFU.

Conclusions

UAE has the highest quality of life improvement (1-year follow-up) for uterine fibroids. HIFU and UAE are safer with shorter hospital stays and quicker recovery time compared with surgery. However, both UAE and HIFU have the risks of re-treatment. However, limited by the number and quality of included studies, the above conclusions need to be verified through more high-quality studies.

The comparison of myomectomy, UAE and MRgFUS in the treatment of uterine fibroids: a meta analysis

OBJECTIVE

To compare the re-intervention rates of myomectomy, uterine artery embolization (UAE) and magnetic resonance-guided focused ultrasound surgery (MRgFUS) for uterine fibroids (UFs) in different follow-up time.

METHODS

Two investigators searched PubMed for clinical studies published in English from 1 Jan 2000 to 31 Dec 2020, and independently examined the paper to select qualified studies, extracted relevant information and assessed the risk of bias. Meanwhile, a meta-analysis of 31 studies containing totally 42103 patients was conducted to compare the re-intervention rate of myomectomy, UAE and MRgFUS.

RESULTS

In the meta-analysis of 42103 patients, the 12-month re-intervention rates of myomectomy, UAE and MRgFUS for UFs were 0.06 (95%CI, 0.01-0.11), 0.07 (95%CI, 0.06-0.09), and 0.12 (95%CI, 0.04-0.20) respectively. The 24-month re-intervention rates were 0.10 (95%CI, 0.04-0.16), 0.08 (95%CI, 0.01-0.17), and 0.14 (95%CI, 0.07-0.21) respectively. The 36-month re-intervention rates were 0.09 (95%CI, 0.05-0.13), 0.14 (95%CI, 0.05-0.23), and 0.22 (95%CI, 0.11-0.32) respectively. Additionally, the 60-month re-intervention rates were 0.19 (95%CI, 0.15-0.24), 0.21 (95%CI, 0.17-0.25), and 0.49 (95%CI, 0.21-0.77) respectively.

CONCLUSIONS

The myomectomy has the lowest re-intervention rate of the three regimens in short time and long time while the MRgFUS has the highest. The rate of MRgFUS increased rapidly in the 60th month after the treatment.

Current and Prospective Treatment of Adenomyosis

(1) Background: Adenomyosis is a poorly understood entity which makes it difficult to standardize treatment. In this paper we review and compare the currently approved medical and surgical treatments of adenomyosis and present the evidence behind them. (2) Methods: A PubMed search was conducted to identify papers related to the different treatments of adenomyosis. The search was limited to the English language. Articles were divided into medical and surgical treatments. (3) Results: Several treatment options have been studied and were found to be effective in the treatment of adenomyosis. (4) Conclusions: Further randomized controlled trials are needed to compare treatment modalities and establish a uniform treatment algorithm for adenomyosis.

Comparison of Uterine Necrosis After Uterine Artery Embolization with Soluble Gelatin Sponge Particles or Tris-acryl Gelatin Microspheres in Swine

PURPOSE

To compare the recanalization of the uterine arteries and uterine necrosis after uterine artery embolization (UAE) using either soluble gelatin sponge particles (SGS), which dissolve in saline, or tris-acryl gelatin microspheres (MS), which are permanent embolic materials, in swine.

METHODS

Fourteen uteri in seven swine were divided into two groups for embolization with either 500-1000 µm SGS (SGS group) or 500-700 µm MS (MS group) (seven uteri per group). The uterine arteries were embolized using SGS or MS, and angiography was performed to evaluate recanalization of the uterine arteries immediately, 1, 2, 3, 4, 5, and 6 h, and 3 days after embolization. On day 3, the uteri were removed to determine the macroscopic necrosis rate and for histopathologic examination.

RESULTS

In the SGS group, four uterine arteries were completely recanalized, two were partially recanalized, and one was still occluded 5 h after embolization. In contrast, all seven uterine arteries in the MS group were still occluded 6 h after embolization. The complete recanalization rate at 3 days was significantly greater in the SGS group than in the MS group (100.0% vs. 14.3%, respectively; P = .0047). The mean uterine necrosis rate was not significantly different between the SGS and MS groups (15.0 ± 15.7% vs. 26.8 ± 13.3%, respectively; P = .096). The mean smallest arterial diameter containing embolic materials was 48.2 ± 22.0 μm (range 21-109 μm) for SGS and 446.7 ± 107.0 μm (range 352-742 μm) for MS (P < .0001).

CONCLUSION

The uterine arteries recanalized earlier in the SGS group than in the MS group and the uterine necrosis rates were similar in both groups. SGS have the potential for a more distal penetration in comparison with MS.

Can uterine artery embolization be an alternative to plastic and reconstructive uterus operation by minimally invasive surgery?

Introduction: Plastic and reconstructive minimally invasive surgery has been established as gold standard in myomectomy. Therapy failure eventually leads to future surgical interventions or hysterectomy: surgeons and patients should be aware of the risks and benefits. We conducted a systematic review to analyse the evidence on the therapeutic indications and adverse events associated with uterine artery embolization and thereby evaluating if this method could be a valid alternative therapy. Methods: In concordance with PRISMA guidelines, literature research was made in PubMed, Cochrane Library, UpToDate, Amboss and Medline databases. Clinical trials, reviews and case reports published in English between January 2010 and June 2020 were included. Results: 44 articles were included out of 838 papers identified at initial search. Regarding uterine fibroids, three original papers and one Cochrane review reported the benefits of the procedure as an alternative to surgery, even in large and giant fibroids. Furthermore, several studies discussed the use of embolization for postpartum haemorrhage to decrease rates of hysterectomy after other haemostatic methods were exhausted, because of the potential risk of abnormal placentation in a future pregnancy. The procedure can also be successfully used as prophylactic method in different obstetrical procedures. Conclusions: The use of embolization in different uterine pathologies is a minimally invasive procedure as an alternative to surgery, especially in women who desire to preserve their uterus. Its related complications are described and can be avoided by a stringent indication of the procedure. More evidence regarding fertility after UAE, use of the procedure prophylactically in obstetrical haemorrhage or in adenomyosis is needed.

Uterine Artery Embolization for Uterine Fibroids: A Closer Look at Misperceptions and Challenges

Uterine artery embolization (UAE) has been shown to be a safe and effective treatment for symptomatic uterine fibroids, with over 25 years of supporting data. Although UAE is a well-established treatment option, several misperceptions exist that may limit the number of patients who are considered candidates for UAE. There are also challenges that may affect the ability of interventional radiologists to effectively treat some patients and offer the best possible experience. This article will discuss these misperceptions and challenges, which represent opportunities for further growth and innovation that will allow interventional radiologists to better serve this patient population.

Comparison between the outcome of single versus multiple uterine fibroids after uterine artery embolization

Background

Uterine fibroids are the most common benign tumor of the reproductive tract in women. Uterine artery embolization has been approved as an alternative treatment option for uterine fibroids to reduce uterine and fibroid volumes as well as to relieve the patient symptoms. The current study included 80 patients with symptomatic uterine fibroids. All patients underwent pre-embolization MRI, uterine artery embolization, and follow-up post-embolization MRI at 6 months post procedure for a reduction in uterine and dominant fibroid volumes. The aim of the study was to assess the role of transcatheter uterine artery embolization in reducing the uterine fibroid volume.

Results

There was a significant difference in the uterine volume reduction between a group with single fibroids and a group with multiple uterine fibroids The mean uterine volume reduction in the first group was 46.5% compared to 37.4% reduction in the second group. While there was no significant difference in the dominant fibroid volume reduction between both groups (48.8% and 44.9% respectively).

Conclusions

UAE has a high efficacy in the reduction of both the uterine volume and the dominant fibroid volume, which results in improvement in patient’s quality of life.

Uterine artery embolization versus surgical treatment in patients with symptomatic uterine fibroids: Protocol for a systematic review and meta-analysis of individual participant data

OBJECTIVE

Uterine fibroids are the most common benign tumours in women of the reproductive age. Symptoms of heavy menstrual bleeding, abdominal discomfort and infertility may seriously affect a woman's quality of life. Uterine artery embolization is a safe and effective alternative treatment to hysterectomy or myomectomy for symptomatic uterine fibroids. Which treatment provides the highest quality of life, least complications, symptom reduction and least chance intervention, has not been established and might depend on strict patient selection. This study aims to identify which specific subgroups benefit most of each treatment by analyzing individual participant data derived from randomized controlled trials of women undergoing embolization or surgical treatment. This study will primarily assess the effectiveness of both treatment groups by evaluating the effect on quality of life of embolization in comparison to surgery on specific patient and fibroid characteristics and the possible need for re-intervention for fibroid-related symptoms.

DATA SOURCES

PubMed/MEDLINE, Embase and The Cochrane Library were searched up to August 2020.

STUDY ELIGIBILITY CRITERIA

We will collect individual participant data from randomized controlled trials that studied clinical and procedural outcomes of premenopausal women with symptomatic uterine fibroids, who were randomized between uterine artery embolization and surgery.

STUDY APPRAISAL AND SYNTHESIS METHODS

Individual participant data from all eligible trials will be sought and analysed according to intention-to-treat principle. Risk of Bias will be done by using version 2 of the Cochrane tool for Risk of Bias in randomized trials. Subgroup analyses to explore the effect of e.g. age, fibroid characteristics and fibroid complaints will be performed, if data is available. This individual patient data meta-analysis will be analysed according to a one-stage model.

A multi-centre, randomized, non-inferiority trial to compare ulipristal with standard surgical treatment in women with symptomatic uterine fibroids: Protocol of the MYOMEX-2 trial

OBJECTIVES

Fibroids are the most common benign tumours found in the uterus and can cause various symptoms. In 20-50 % of the women, an intervention is required. When conservative options fail, invasive options such as hysterectomy, uterine artery embolization or myomectomy are eligible options. Ulipristal acetate (UPA) was launched as the sole available long term pharmaceutical treatment, with the potential to avoid surgery. It is suggested that UPA improves quality of life, reduces symptoms and fibroid volumes. However, UPA is an expensive medicine, is possibly associated with liver injury and has never been directly compared to surgical treatment. The aim of this trial is to compare UPA to surgical treatment on both effectiveness and cost-effectiveness. Primary outcome is the reduction in symptom severity scores (part of the Uterine Fibroid Symptom and Quality of Life questionnaire) at 24 months of follow-up compared to baseline. Secondary outcomes include quality of life, societal costs, societal participation, liver function variation, patient satisfaction and preference. Outcomes will be analysed according to intention-to-treat principle.

STUDY DESIGN

The MYOMEX-2 trial is an open-label, multicentre, non-inferiority randomized controlled trial. Patients are pre-menopausal women with symptomatic fibroids eligible for surgical treatment (hysterectomy, myomectomy or UAE). Fibroid symptoms may comprise (but are not limited to) heavy menstrual bleeding, bulk symptoms or pain. Patients are randomised 2:1 in a parallel group design between two treatment arms: 119 patients in the UPA group and 60 patients in the surgery group. Follow up comprises of online questionnaires, outpatient visits and phone appointments on several follow up moments, up to 24 months after surgery or start UPA.

REGISTRATION DETAILS

MYOMEX-2 trial; protocol version 4, date 22-02-2019; NTR6860; NL62638.029.18. All items from the World Health Organization Trial Registration Data Set are provided in the online supplementary file (Appendix-B).

Utilization of Endovascular and Surgical Treatments for Symptomatic Uterine Leiomyomas: A Population Health Perspective

PURPOSE

To conduct a population-level analysis of surgical and endovascular interventions for symptomatic uterine leiomyomata by using administrative data from outpatient medical encounters.

MATERIALS AND METHODS

By using administrative data from all outpatient hospital encounters in California (2005-2011) and Florida (2005-2014), all patients in the outpatient setting with symptomatic uterine leiomyomata were identified. Patients were categorized as undergoing hysterectomy, myomectomy, uterine artery embolization (UAE), or no intervention. Hospital stay durations and costs were recorded for each encounter.

RESULTS

A total of 227,489 patients with uterine leiomyomata were included, among whom 39.9% (n = 90,800) underwent an intervention, including hysterectomy (73%), myomectomy (19%), or UAE (8%). The proportion of patients undergoing hysterectomy increased over time (2005, hysterectomy, 53.2%; myomectomy, 26.9%; UAE, 18.0%; vs 2013, hysterectomy, 80.1%; myomectomy, 14.4%; UAE, 4.0%). Hysterectomy was eventually performed in 3.5% of patients who underwent UAE and 4.1% who underwent myomectomy. Mean length of stay following hysterectomy was significantly longer (0.5 d) vs myomectomy (0.2 d) and UAE (0.3 d; P < .001 for both). The mean encounter cost for UAE ($3,772) was significantly less than those for hysterectomy ($5,409; P < .001) and myomectomy ($6,318; P < .001). Of the 7,189 patients who underwent UAE during the study period, 3.5% underwent subsequent hysterectomy.

CONCLUSIONS

The proportion of women treated with hysterectomy in the outpatient setting has increased since 2005. As a lower-cost alternative with a low rate of conversion to hysterectomy, UAE may be an underutilized treatment option for patients with uterine leiomyomata.

Non-extirpative Treatments for Uterine Myomas: Measuring Success

OBJECTIVE

To analyze outcomes of nonextirpative treatments for uterine myomas compared with myomectomy.

DATA SOURCES

A systematic search of the following databases from inception to January 2020 was performed: Ovid Medline, Embase, PubMed, and Cochrane Controlled Register of Trials.

METHODS OF STUDY SELECTION

Two authors reviewed titles and abstracts for relevance, and full articles were obtained and evaluated for inclusion. Studies were included if they compared nonextirpative interventions for uterine myomas to myomectomy and reported at least one outcome of interest.

TABULATION, INTEGRATION, AND RESULTS

Of the 2010 articles identified and reviewed, 125 full text articles were reviewed, and 22 were ultimately included in the analysis. Nonextirpative treatments reviewed included uterine artery embolization (UAE; 16 studies, n = 9555 subjects), focused ultrasound (FUS; 4 studies, n = 1516), laparoscopic radiofrequency ablation (RFA; 3 studies, n = 49). UAE, FUS, and laparoscopic RFA groups were compared with patients undergoing myomectomy (n = 34 872, n = 20 677, n = 47 respectively). In comparison with myomectomy, UAE had similar quality of life scores, symptom severity scores, sexual function scores, ovarian function, and miscarriage rates following intervention. There was lower likelihood of conceiving after UAE and a higher rate of reintervention after UAE compared with myomectomy. FUS had similar postprocedure sexual function scores and reintervention rates compared with myomectomy. Laparoscopic RFA had similar quality of life scores, symptom severity scores, sexual function scores, reintervention rates, and pregnancy rates after the procedure compared with myomectomy.

CONCLUSION

Nonextirpative treatments for uterine myomas have similar outcomes to myomectomy in multiple domains, with most available evidence comparing UAE with myomectomy.

Uterine-Artery Embolization or Myomectomy for Uterine Fibroids

BACKGROUND

Uterine fibroids, the most common type of tumor among women of reproductive age, are associated with heavy menstrual bleeding, abdominal discomfort, subfertility, and a reduced quality of life. For women who wish to preserve their uterus and who have not had a response to medical treatment, myomectomy and uterine-artery embolization are therapeutic options.

METHODS

We conducted a multicenter, randomized, open-label trial to evaluate myomectomy, as compared with uterine-artery embolization, in women who had symptomatic uterine fibroids and did not want to undergo hysterectomy. Procedural options included open abdominal, laparoscopic, or hysteroscopic myomectomy. The primary outcome was fibroid-related quality of life, as assessed by the score on the health-related quality-of-life domain of the Uterine Fibroid Symptom and Quality of Life (UFS-QOL) questionnaire (scores range from 0 to 100, with higher scores indicating a better quality of life) at 2 years; adjustment was made for the baseline score.

RESULTS

A total of 254 women, recruited at 29 hospitals in the United Kingdom, were randomly assigned: 127 to the myomectomy group (of whom 105 underwent myomectomy) and 127 to the uterine-artery embolization group (of whom 98 underwent embolization). Data on the primary outcome were available for 206 women (81%). In the intention-to-treat analysis, the mean (±SD) score on the health-related quality-of-life domain of the UFS-QOL questionnaire at 2 years was 84.6±21.5 in the myomectomy group and 80.0±22.0 in the uterine-artery embolization group (mean adjusted difference with complete case analysis, 8.0 points; 95% confidence interval [CI], 1.8 to 14.1; P = 0.01; mean adjusted difference with missing responses imputed, 6.5 points; 95% CI, 1.1 to 11.9). Perioperative and postoperative complications from all initial procedures, irrespective of adherence to the assigned procedure, occurred in 29% of the women in the myomectomy group and in 24% of the women in the uterine-artery embolization group.

CONCLUSIONS

Among women with symptomatic uterine fibroids, those who underwent myomectomy had a better fibroid-related quality of life at 2 years than those who underwent uterine-artery embolization.

Quality of Life after Laparoscopic and Open Abdominal Myomectomy

STUDY OBJECTIVE

To evaluate the baseline and postoperative changes in quality of life and symptom-severity scores in women undergoing laparoscopic or open abdominal myomectomy for symptomatic myomas.

DESIGN

Prospective cohort study of patients choosing myomectomy for symptomatic uterine myomas.

SETTING

Academic medical center.

PATIENTS

A total of 143 women enrolled in the study. Of these, 80 women completed both a preoperative questionnaire and at least 1 postoperative questionnaire between 6 and 27 months after surgery.

INTERVENTIONS

A total of 52 women had open abdominal myomectomy, and 28 had laparoscopic myomectomy between October 2014 and September 2017.

MEASUREMENTS AND MAIN RESULTS

The results of the Uterine Fibroid Symptom and Health-Related Quality-of-Life Questionnaire were compared before and after laparoscopic or open myomectomy. Women undergoing open abdominal myomectomy had larger and more numerous myomas than women undergoing laparoscopic myomectomy. Baseline quality-of-life scores were less adversely affected for women having laparoscopic myomectomy (mean [standard deviation], 57 [24] laparoscopic vs 43 [19] open abdominal, p = .01). However, baseline symptom-severity scores were statistically similar (49 [22] for laparoscopic and 57 [20] for open abdominal, p = .08) approaches. Six to 12 months after surgery, both open abdominal and laparoscopic surgeries provided excellent and similar improvements in symptom-severity and quality of life (postoperative symptoms severity scores, mean [standard deviation], 20 [14] laparoscopic vs 13 [11] open abdominal, p = .24 and quality-of-life scores, mean [standard deviation], 91 [16] laparoscopic vs 88 [17] open abdominal, p = .49). These improvements were sustained for women who returned questionnaires up to 27 months of follow-up.

CONCLUSION

Women with symptomatic myomas have a compromised quality of life, and they experience a similarly dramatic improvement in quality of life and decrease in symptom-severity after both laparoscopic and open abdominal myomectomies.

Predicting the Fibroid-Migratory Impact of UAE: Role of Pre-embolization MRI Characteristics

Aim

To investigate potential factors on MR imaging that could be used to predict migration of uterine fibroids post-UAE.

Methods and Materials

We retrospectively reviewed patients referred for UAE having pre-procedural and 6 months post-procedural MRI, at a tertiary centre, over a 1-year period. Pre- and post-UAE images were reviewed in 64 women by two radiologists to identify the sub-type, dimensions, and infarction rate of each dominant fibroid. The shortest distance between the fibroid and the endometrial wall was measured to determine intramural fibroid movement. Paired sample T tests and two-sample T tests were used to compare between pre- and post-embolization variations and between migrated and non-migrated intramural fibroids, respectively. After preliminary results suggested potential predictors of intramural fibroids migration, we tested our findings against the non-dominant intramural fibroids in the same patients.

Results

Review of images revealed 35 dominant intramural fibroids, of which eight migrated to become submucosal fibroids, while five were either partially or completely expelled. These 13 migrated fibroids had a shorter pre-procedural minimum endometrial distance (range 1–2.4 mm) and greater maximum fibroid diameter (range 5.1–18.1 cm), when compared to non-migrating fibroids. On image reassessment, the migrated non-dominant intramural fibroids had a minimum endometrial distance and maximum fibroid diameter within the same range.

Conclusion

Intramural fibroids with a minimum endometrial distance less than 2.4 mm and a maximum fibroid diameter greater than 5.1 cm have a high likelihood of migrating towards the endometrial cavity after UAE.
