The challenge of FIGO type 3 leiomyomas and infertility: Exploring therapeutic alternatives amidst limited scientific certainties. Int J Gynaecol Obstet 2024; 165:975-987. [PMID: 38009829 DOI: 10.1002/ijgo.15260] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 10/28/2023] [Accepted: 11/08/2023] [Indexed: 11/29/2023]
Abstract
Uterine leiomyomas (ULs) are non-cancerous tumors composed of smooth muscle cells that develop within the myometrium and represent the most prevalent pathological condition affecting the female genital tract. Despite the volume of available research, many aspects of ULs remain unresolved, making it a "paradoxical disease" where the increase in available scientific literature has not been matched by an increase in solid evidence for clinical management. Fertility stands at the top of the list of clinical issues where the role of ULs is still unclear. The leiomyoma subclassification system, released by the International Federaion of Gynecology and Obstetrics (FIGO) in 2008, introduced a new and more effective way of categorizing uterine fibroids. The aim was to go beyond the traditional classification "subserosal, intramural and submucosal", facilitating a detailed examination of individual ULs impact on the female reproductive system. The "type 3 UL" is a special type of myoma, characterized by its complete myometrial development while encroaching the endometrium. It is a unique "hybrid" between a submucous and an intramural UL, that may exert a detrimental "double hit" mechanism, which is of particular interest in patients wishing pregnancy. To date, no robust evidence is available regarding the management of type 3 ULs. The aim of this narrative review is to provide a comprehensive overview of the physiopathological mechanisms that type 3 UL may exert on fertility, and to present new perspectives that may help us to better understand both the need for and the methods of treating this unique type of fibroid.

High-intensity Focused Ultrasound is a Better Choice for Women with Fertility Desire: A Systematic Review and Meta-analysis of the Comparison between High-intensity Focused Ultrasound and Laparoscopic Treatment of Uterine Fibroids. Gynecol Minim Invasive Ther 2024; 13:79-89. [PMID: 38911304 PMCID: PMC11192288 DOI: 10.4103/gmit.gmit_23_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 08/17/2023] [Accepted: 08/18/2023] [Indexed: 06/25/2024] Open
Abstract
High-intensity focused ultrasound (HIFU) is commonly used to treat uterine fibroids and adenomyosis, but there is no evidence using metadata to compare fertility outcomes between conventional laparoscopic procedures and HIFU. The purpose of this study analysis is that evidence-based fertility outcomes may provide better treatment options for clinicians and patients considering fertility. The literature on fertility data for HIFU surgery versus laparoscopic myomectomy was searched in seven English language databases from January 1, 2010, to November 23, 2022. A total of 1375 articles were received in the literature, 14 of which were selected. We found that women who underwent HIFU surgery had higher rates of spontaneous pregnancy, higher rates of spontaneous delivery, and higher rates of full-term delivery but may have higher rates of miscarriage or postpartum complications than women who underwent laparoscopic myomectomy. Looking forward to future studies, it is hoped that the literature will examine endometrial differences in women who undergo HIFU and laparoscopic myomectomy to demonstrate the ability of endometrial repair. The location of fibroids in the sample should also be counted to allow for attribution statistics on the cause of miscarriage.

The Impact of Laparoscopic Myomectomy on Pregnancy Outcomes: A Systematic Review. J Pers Med 2024; 14:340. [PMID: 38672967 PMCID: PMC11051497 DOI: 10.3390/jpm14040340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Revised: 03/09/2024] [Accepted: 03/20/2024] [Indexed: 04/28/2024] Open
Abstract
STUDY OBJECTIVE The objective of this systematic review is to investigate the impact of laparoscopic myomectomy techniques on pregnancy outcomes, with a specific focus on the correlation between the type of suture used during the procedure and the incidence of uterine rupture. Additionally, the study aims to examine how the localization and size of myomas, key factors in laparoscopic myomectomy, may influence fertility outcomes. DATA SOURCES extensive searches were conducted using MDPI, PubMed, Web of Science, and Cochrane Library databases from 2008 to November 2023. METHODS OF STUDY SELECTION The study involved women of reproductive age diagnosed with fibroids who underwent surgical removal of fibroids using either laparotomy or laparoscopy. The evaluation of pregnancy outcomes focused on indicators such as live birth rates, miscarriage rates, stillbirth rates, premature delivery rates, and cases of uterine rupture. Quality assessment was systematically performed by employing the National Institutes of Health Study Quality Assessment Tools, with the subsequent formulation of clinical recommendations that were meticulously graded in accordance with the robustness of the underlying evidence. RESULTS The pregnancy outcomes post-myoma treatment, as reflected in one of the presented tables, show a promising number of pregnancies and live births, but also indicate the potential risks of miscarriages and preterm births. The diversity in outcomes observed among various studies underscores the imperative for tailored patient care, as well as the necessity for additional research aimed at optimizing fertility and pregnancy outcomes following myoma treatment. CONCLUSION This study offers insights into the criteria for patient selection and intraoperative methodologies specifically related to laparoscopic myomectomy. To enhance our understanding of the associations between fibroid characteristics (location, size) and reproductive outcomes, additional research is warranted, particularly through well-designed clinical trials.

Abstract
BACKGROUND Microwave endometrial ablation (MEA) is a minimally invasive treatment method for heavy menstrual bleeding. However, additional treatment is often required after recurrence of uterine myomas treated with MEA. Additionally, because this treatment ablates the endometrium, it is not indicated for patients planning to become pregnant. To overcome these issues, we devised a method for ultrasound-guided microwave ablation of uterine myoma feeder vessels. We report three patients successfully treated for heavy menstrual bleeding, secondary to uterine myoma, using our novel method. CASE SUMMARY All patients had a favorable postoperative course, were discharged within 4 h, and experienced no complications. Further, no postoperative recurrence of heavy menstrual bleeding was noted. Our method also reduced the myoma's maximum diameter. CONCLUSION This method does not ablate the endometrium, suggesting its potential application in patients planning to become pregnant.

Abstract
High-intensity focused ultrasound (HIFU) has emerged as a promising uterus-sparing and possibly fertility-sparing treatment modality for women with adenomyosis, especially those who desire to conceive. We conducted this systematic review and performed a meta-analysis on clinical studies aimed to improve reproduction in women with adenomyosis. After extensive search of PubMed and CNKI, we identified 10 studies published in English and Chinese involving a total of 557 patients with adenomyosis who desired to conceive after HIFU treatment. We found a pooled estimate of pregnancy rate of 53.4% and of the live birth rate of 35.2%, and there was a substantial heterogeneity among these studies. While there is a potential for HIFU treatment to improve fertility for patients with adenomyosis who desired to conceive, such evidence is very weak as of now. Comparative studies with much higher methodological rigor, preferably randomized clinical trials, are badly needed to further illuminate this issue.

Abstract
OBJECTIVE The aim of the work described here was to explore the clinical efficacy and safety of ultrasound-guided high-intensity focused ultrasound (USg-HIFU) treatment in women with multiple fibroids and identify the characteristic parameters predicting USg-HIFU efficacy in multiple fibroids. METHODS From February 2021 to August 2022, 138 patients with multiple fibroids (group A comprising 125 patients with two to four fibroids and 13 patients with five or more fibroids) and 149 patients with solitary fibroids (group B) were included. HIFU treatment information, efficacy comparisons and adverse events were recorded. A nomogram model of the characteristic parameters used to predict the efficacy of USg-HIFU in multiple fibroids was established. RESULTS After USg-HIFU treatment, the statistical comparison of pre-operative versus post-operative symptom scores and fibroid volume in the two groups indicated obvious symptom relief and substantial shrinkage of fibroid volume (all p values <0.001). Nevertheless, group A required more energy and longer treatment and sonication times to achieve a 70% non-perfused volume (NPV) ratio, and had a lower energy efficiency factor than group B (all p values <0.05). No severe complications were observed in either group. The nomogram model included fibroid volume, fibroid location and signal intensity on T2-weighted imaging (T2WI). The area under the receiver operating characteristic curve and the accuracy of the model were 0.698 and 0.686, respectively. CONCLUSION USg-HIFU appears to be an effective and safe treatment option for multiple fibroids. Knowledge of the fibroid volume, location and signal intensity on T2WI may help determine the efficacy of USg-HIFU in multiple fibroids.

Abstract
Leiomyomas, or uterine fibroids, are growths consisting of muscle and tissue that develop in or on the uterine wall. The most frequent benign uterine tumours in women of reproductive age are thought to be fibroids. Dysmenorrhea, spotting, hypermenorrhoea, abdominal pain, pressure on surrounding organs, and issues with micturition and defecation are among the symptoms that are often present. Fibroids can form as a single nodule or as a cluster. Uterine fibroids, especially large submucosal and intramural uterine fibroids, can cause obstacles to implantation and lead to pregnancy loss. Uterine fibroids can be treated without surgery and with little downtime using focused ultrasound. There is published research showing that women can conceive and have healthy children after therapy, thus protecting fertility. The ablation of uterine fibroids by high-intensity focused ultrasound (HIFU) is successful since the volume of the fibroids is significantly reduced.

Reproductive and Obstetric Outcomes after UAE, HIFU, and TFA of Uterine Fibroids: Systematic Review and Meta-Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:ijerph20054480. [PMID: 36901489 PMCID: PMC10001943 DOI: 10.3390/ijerph20054480] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Revised: 02/24/2023] [Accepted: 03/01/2023] [Indexed: 06/07/2023]
Abstract
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.

Abstract
OBJECTIVES To compare pregnancy outcomes after high-intensity focused ultrasound ablation (HIFU), myomectomy and uterine artery embolization (UAE) for fertility-sparing patients with uterine fibroids and to investigate the possible mechanism of improving pregnancy by HIFU. MATERIALS AND METHODS A meta-analysis of 54 studies containing 12,367 patients was conducted to compare the pregnancy outcomes of three fertility-sparing therapies. And a retrospective self-control study of 26 patients with uterine fibroids from May 2019 to December 2020 was performed to assess the blood flow impedance of bilateral uterine arteries before and after HIFU. RESULTS In the analysis by treatment option, the pregnancy rate after myomectomy was 0.43 (95% CI 0.36-0.49), which was higher than 0.18 (95% CI 0.10-0.26) after HIFU, the latter was significantly higher than that after UAE (ratio 0.08, 95% CI 0.06-0.10). The miscarriage rate after HIFU was 0.08 (95% CI 0.04-0.12), which was similar to 0.15 (95% CI 0.09-0.21) after myomectomy and also similar to 0.16 after UAE (95% CI 0.01-0.30). In the subgroup analysis, women who received ultrasound guided HIFU (USgHIFU) were more likely to have ideal pregnancy outcomes than that after magnetic resonance imaging-guided HIFU. The pulsatility index and resistance index on the right side were significantly higher 3 months after HIFU than before (1.637 ± 0.435 vs. 1.845 ± 0.469; p = 0.033; 0.729 ± 0.141 vs. 0.784 ± 0.081, p = 0.039). CONCLUSIONS HIFU, especially USgHIFU, may be an alternative fertility-sparing modality for patients with uterine fibroids over 40 years old. HIFU may contribute to improving pregnancy rates by elevating uterine blood flow impedance.

Jindal S, Jung J, Lee K, Chern B. High-intensity focused ultrasound for the treatment of fibroids: A single-center experience in Singapore. Gynecol Minim Invasive Ther 2023; 12:15-25. [PMID: 37025438 PMCID: PMC10071864 DOI: 10.4103/gmit.gmit_102_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 10/05/2022] [Accepted: 11/15/2022] [Indexed: 02/11/2023] Open
Abstract
Objectives Uterine fibroids and adenomyosis are common gynecological conditions that often require surgical treatment. Minimally invasive interventions such as ultrasound-guided high-intensity focused ultrasound (USgHIFU) are gaining popularity as they avoid surgical morbidity and conserve the uterus. We present a single-center experience on the use of USgHIFU for the treatment of fibroids and adenomyosis. Materials and Methods This was a retrospective study of 167 patients who underwent USgHIFU for uterine fibroids and adenomyosis between July 2018 and December 2020. Relevant demographic data and pre- and post-intervention fibroid volume, symptom severity scores (SSS), and health-related quality of life (QOL) scores were collected and compared. The paired t-test or Wilcoxon signed-rank test was used to compare the difference before and after treatment. P < 0.001 was considered statistically significant. Results One hundred and sixty-seven patients with fibroids or adenomyosis were included in this study. The mean age of the cohort was 42-year-old. USgHIFU treatment led to a reduction in mean fibroid volume, improvement in SSS, and health-related QOL scores. The average reduction in mean fibroid volume was 68% and 75% at 6 and 12 months, respectively. There was a significant reduction in SSS (46.9 [pre] vs. 15.6 [post], P < 0.001) and improvement in health-related QOL scores at 6 months (58 [pre] vs. 86 [post], P < 0.001). The re-intervention rate following USgHIFU was 7.7% and successful pregnancy post USgHIFU was reported in 6 patients. Conclusion USgHIFU is safe and effective. In women who desire fertility or are not suitable for surgery, it is a good alternative option. It should be included in the armamentarium for the treatment of uterine fibroids and adenomyosis.

Improvement of fibroid-associated symptoms and quality of life after US-guided high-intensity focused ultrasound (HIFU) of uterine fibroids. Sci Rep 2022; 12:21155. [PMID: 36476975 PMCID: PMC9729612 DOI: 10.1038/s41598-022-24994-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Accepted: 11/23/2022] [Indexed: 12/12/2022] Open
Abstract
Uterine fibroids are the most common benign uterine tumors and can cause various severe symptoms as abnormal menstrual bleeding or pelvic pain. Therefore, the primary objective in the treatment of uterine fibroids is a sufficient symptom relief. Ultrasound (US)-guided High-intensity focused ultrasound (HIFU) is an effective non-invasive treatment strategy for ablation of uterine fibroids that can achieve a significant tumor volume reduction. The aim of the study is to evaluate if US-guided HIFU treatment can reduce fibroid-associated symptoms leading to an improvement of health-related quality of life. Fifty-five women with symptomatic uterine fibroids underwent US-guided HIFU ablation. Clinical evaluation was performed on the basis of the Uterine Fibroid Symptom and Health-Related Quality of Life Questionnaire (UFS-QOL) at baseline, 6 weeks, 3, 6, 9 and 12 months after HIFU. Imaging follow-up included contrast-enhanced ultrasound (CEUS) and contrast-enhanced MRI. A significant reduction of the Symptom Severity Scale (SSS) was observed between 6 weeks and 12 months after HIFU (49.9 ± 19.4 at baseline vs. 42.2 ± 20.1 at 6 weeks and 23.6 ± 12.7 at 12 months after treatment, p < 0.001) correlating with a significant improvement (p < 0.001) of Health-related Quality of Life (HRQL) (52.5 ± 22.7 at baseline vs. 59.8 ± 22 at 6 weeks and 77.9 ± 17.3 at 12 months after treatment). Significant postinterventional improvement was observed in every subscale of HRQL. In the majority of patients, only minor, short-lasting and self-limiting side effects were observed, e.g. soft tissue edema of the anterior lower abdominal wall in the acoustic pathway or transient moderate lower abdominal pain as during menstruation. One patient with a very large fibroid experienced strong short-lasting pain after the procedure; two patients experienced post-procedurally a transient sciatic nerve irritation. US-guided HIFU of uterine fibroids reduces disease-related symptoms and improves health-related quality of life.

Abstract
Microwave endometrial ablation (MEA) is a minimally invasive treatment for uterine myoma with hypermenorrhea, which can replace conventional hysterectomy. However, cases requiring additional treatment because of postoperative recurrence are often encountered. MEA cauterizes the endometrium and is not recommended for patients who wish to preserve fertility. We present the cases of a patient with myoma-related hypermenorrhea who underwent microwave ablation of the inflowing blood vessels to the uterine myoma under transvaginal ultrasound guidance. A 43-year-old woman was diagnosed with chronic myeloid leukemia and treated with dasatinib 2 years ago. Worsening hypermenorrhea was observed after treatment initiation. Ultrasound and pelvic magnetic resonance imaging revealed a uterine myoma. Therefore, she underwent MEA under transvaginal ultrasound guidance. Visual analog scale evaluation demonstrated considerable improvement in hypermenorrhea and dysmenorrhea; the myoma size showed reduction. The postoperative course was uneventful, and the patient was discharged on the day after surgery. No postoperative complications were observed. This patient is currently undergoing infertility treatment. The microwave ablation of myoma under transvaginal ultrasound guidance can effectively and safely reduce the myoma size. These findings suggest that this method is a novel treatment option for patients with myoma-related hypermenorrhea who wish to preserve their fertility and have children.

Abstract
OBJECTIVE To assess the feasibility of vaginal delivery after HIFU. METHODS A total of 37 women who met the trial of labor after HIFU (TOLAH) inclusion criteria and 368 women who met the trial of labor after cesarean delivery (TOLAC) inclusion criteria gave birth at Shanghai First Maternity and Infant Hospital between 14th June 2018 and 24th September 2021. The delivery outcomes of the two groups were compared. Multivariable logistic regression analysis was used to estimate the adjusted risk of postpartum hemorrhage (PPH). RESULTS In the Qualified Candidates for TOLAH group, vaginal delivery is substantially less common (p = 0.000). The prevalence of PPH in the Qualified Candidates for TOLAH group is lower than in the Candidates for TOLAC group (8.82% vs 10.51%, p = 0.534; 0% vs 2.51%, p = 0.418). Hemoglobin drop in the Qualified Candidates for TOLAH group is also lower (7.03 ± 7.39vs 12.11 ± 12.62, p = 0.001). The rate of using more than two types of uterotonic medications to promote contraction is significantly lower in the Qualified Candidates for TOLAH group (54.05% vs 69.84%, p = 0.04), and the percentage of abnormal uterine contraction is lower in the Qualified Candidates for TOLAH group (35.14% vs 49.18%, p = 0.072). PPH is strongly predicted by abnormal uterine contraction (aOR: 17.177, 95% CI:5.046 ∼ 58.472, p = 0.000), but not by HIFU (aOR:1.105; 95% CI:0.240 ∼ 5.087, p = 0.898). No uterine rupture occurred in the cases after HIFU. CONCLUSIONS No uterine rupture occurred in our study group after HIFU. HIFU is not a risk for PPH. It is promising for those after HIFU to choose vaginal delivery.

Abstract
OBJECTIVE High-intensity focused ultrasound (HIFU) therapy is a noninvasive alternative to conventional abdominal surgery in obstetrics and gynecology. The aim of this study is to evaluate the reduction of pain intensity with bowel manipulation before ultrasound-guided HIFU treatment in women with posterior wall uterine fibroids and/or adenomyosis. MATERIALS AND METHODS This is a multicenter retrospective observational study. Data from all patients who underwent HIFU therapy at three HIFU clinics (Sichuan Maternal and Child Health Hospital, Xiangya Hospital of Central South University, and Kuo General Hospital) between January 2019 and December 2019 were analyzed. We compared pain intensity with and without bowel manipulation during the HIFU treatment and evaluated tolerability without intravenous sedation. The presence of discomfort or pain during the HIFU procedure was evaluated using the visual analog scale (VAS). RESULTS A total of 86 women were included in this study. All women underwent HIFU therapy with the PRO-2008 system in the supine position for posterior wall uterine fibroids and/or adenomyosis. Thirty-seven women received pretreatment anal catheterization with a condom and 49 women were not subjected to bowel manipulation. All patients received pretreatment condom-catheter device were well tolerated during the procedure of bowel manipulation. During the HIFU procedure, the women who had received bowel manipulation experienced lower pain intensity, especially less sacrococcygeal pain (VAS score 1.56 ± 1.46 vs 2.89 ± 1.61), target region pain (1.54 ± 1.30 vs 2.53 ± 1.29), and radiating pain (0.13 ± 0.34 vs 0.41 ± 0.54), compared with the women without bowel manipulation. CONCLUSION Bowel manipulation with anal catheterization before HIFU therapy for posterior wall uterine masses can be safely performed and is effective as a low risk intervention to aid in reducing potential HIFU complications related to nerve involvement.

Abstract
OBJECTIVE To examine the effectiveness and safety of thermal ablative methods and myomectomy for the treatment of uterine fibroids. MATERIALS AND METHODS We searched EMBASE, PubMed, the Cochrane Central Register of Controlled Trials, Scopus, CINAHL, ClinicalTrials.gov and Web of Science databases through April 2021. Clinical trials comparing the thermal ablative methods and myomectomy for the treatment of uterine fibroids were included. RESULTS Thirteen studies including 4205 patients were eligible. The thermal ablative treatment group was associated with less major adverse events (only ultrasound guided high-intensity focused ultrasound) (RR, 0.111 [95% CI, 0.070-0.175], p=.0), shorter duration of hospital stays in observational studies (-0.1497 day, [95% CI, -1.593 to -0.321], p=.0) and in randomized controlled trials (RCTs) (-0.844 day, [95% CI, -0.1.142 to -0.546], p=.0), higher uterine fibroid symptom (UFS) score after operation (0.252 [95% CI, 0.165-0.339]; p=.0), transformed symptom severity (tSS) score after operation (0.515 [95% CI, 0.355-0.674]; p=.0) and quality of life (QoL) score after operation (0.188 [95% CI, 0.093-0.283]; p=.0) in comparison with myomectomy group. No statistically significant difference was found between the thermal ablative treatment group and myomectomy group with respect to reintervention rate and pregnancy rate. CONCLUSION The current data available demonstrate that thermal ablative methods were not inferior to myomectomy in the treatment of uterine fibroids. The findings in this study need to be further confirmed by large RCTs.

Abstract
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.

Abstract
OBJECTIVES To compare the treatment success and safety of ultrasound- and MR-guided high-intensity focused ultrasound (HIFU) with surgery for treating symptomatic uterine fibroids. METHODS We searched studies comparing HIFU with surgery for fibroids in different databases from January 2000 to July 2020. The mean difference (MD) or relative risk (RR) with 95% confidence interval (CI) for different outcome parameters was synthesized. RESULTS We included 10 studies involving 4450 women. Compared with the surgery group, the decrease in uterine fibroid severity score at 6- and 12-month follow-up was higher in the HIFU group (MD - 4.16, 95% CI - 7.39 to - 0.94, and MD - 2.44, 95% CI - 3.67 to - 1.20, p < 0.05). The increase in quality-of-life (QoL) score at 6- and 12-month follow-up was higher in the HIFU group (MD 2.13, 95% CI 0.86 to 3.14, and MD 2.34, 95% CI 0.82 to 3.85, p < 0.05). The duration of hospital stay and the time to return to work was shorter in the HIFU group (MD - 3.41 days, 95% CI - 5.11 to - 1.70, and MD - 11.61 days, 95% CI - 19.73 to - 3.50, p < 0.05). The incidence of significant complications was lower in the HIFU group (RR 0.33, 95% CI 0.13 to 0.81, p < 0.05). The differences in the outcomes of adverse events, symptom recurrence, re-intervention, and pregnancy were not statistically significant (p > 0.05). CONCLUSIONS HIFU is superior to surgery in terms of symptomatic relief, improvement in QoL, recovery, and significant complications. However, HIFU showed comparable effects to surgery regarding the incidence of adverse events, symptom recurrence, re-intervention, and pregnancy. KEY POINTS • HIFU ablation is superior to surgery in terms of symptomatic relief, improvement in QoL, recovery, and significant complications. • HIFU has comparable effects to surgery in terms of symptom recurrence rate, re-intervention rate, and pregnancy rate, indicating that HIFU is a promising non-invasive therapy that seems not to raise the risk of recurrence and re-intervention or deteriorate fertility compared to surgical approaches in women with fibroids. • There is still a lack of good-quality comparative data and further randomized studies are necessary to provide sufficient and reliable data, especially on re-intervention rate and pregnancy outcome.

Abstract
OBJECTIVE To compare the efficacy and safety of high-intensity focused ultrasound (HIFU) and gonadotropin-releasing analogues (GnRH-a) as pretreatments for the hysteroscopic transcervical resection of myoma (TCRM) for type 2 submucosal fibroids greater than 4 centimeters in diameter. MATERIALS AND METHODS Seventy-nine patients were assigned into two groups according patient preference: 42 in HIFU and 37 in GnRHa. TCRM was performed after 3 months of pretreatment with HIFU or GnRHa. RESULTS Following pretreatment with HIFU or GnRHa, uterine-fibroid symptom (UFS) scores and hemoglobin levels (HGB) showed improvement. The fibroid maximum diameter, size of fibroids, and volume of the uterus were decreased. Following HIFU pretreatment, one case reported complete vaginal fibroid expulsion, and four reported partial fibroid expulsion. No similar cases were found in the GnRHa group. Eighteen patients were lost to follow-up prior to TCRM. Among the 31 patients in HIFU, the fibroids were downgraded to type 0 in 10 cases and type 1 in 5 cases. Of the 30 patients in GnRHa, the treated fibroids were downgraded to type 1 in 9 cases. The mean operation time and intraoperative blood loss of the HIFU group were significantly lower than those in the GnRHa group. No significant differences were observed in the incidence of intraoperative complications and the one-time resection rate of fibroids between the two groups (p>.05). CONCLUSIONS HIFU seems to be superior to GnRHa as a pretreatment method prior to TCRM for type 2 submucosal fibroids greater than 4 centimeters in diameter.

Abstract
OBJECTIVE Uterine myomas are one of the most common gynecologic tumors in premenopausal women. The conventional surgical treatments are myomectomy and hysterectomy, but high-intensity focused ultrasound (HIFU) is a new noninvasive treatment creating no surgical wound. The aim of this study was to evaluate the effectiveness and safety of HIFU treatment compared with conventional surgery for patients with uterine myomas. DATA SOURCES PubMed, Embase, and the Cochrane Library were searched for studies published before January 2021. METHODS OF STUDY SELECTION Studies comparing the outcome of HIFU and conventional surgery-myomectomy and hysterectomy-for patients with uterine myomas were included. We conducted meta-analyses by using a random effects model. Uterine myoma symptom score and quality-of-life score were analyzed using the mean difference (MD). The recovery time and frequency of major adverse events were also evaluated. TABULATION, INTEGRATION, AND RESULTS Ten studies were included. HIFU relieved uterine myoma symptoms significantly when compared with conventional surgery at 6 (MD -1.61; 95% confidence interval [CI], -2.88 to -0.33) and 12 (MD -2.44; 95% CI, -3.68 to -1.20) months after treatment. Similarly, HIFU group improve the quality-of-life score significantly at 6 (MD 2.14; 95% CI, 0.86-3.42) and 12 (MD 2.34; 95% CI, 0.82-3.86) months after treatment when compared with the surgery group. CONCLUSION HIFU could be an effective and safe treatment option for patients with uterine myomas. However, one of its side effects, skin burns, requires further research and discussion. Additional studies involving more randomized controlled trials are warranted.

Abstract
Image-guided high-intensity focused ultrasound (HIFU) has been increasingly used in medicine over the past few decades, and several systems for such have become commercially available. HIFU has passed regulatory approval around the world for the ablation of various solid tumors, the treatment of neurologic diseases, and the palliative management of bone metastases. The mechanical and thermal effects of focused ultrasound provide a possibility for histotripsy, supportive radiation therapy, and targeted drug delivery. The integration of imaging modalities into HIFU systems allows for precise temperature monitoring and accurate treatment planning, increasing the safety and efficiency of treatment. Preclinical and clinical results have demonstrated the potential of image-guided HIFU to reduce adverse effects and increase the quality of life postoperatively. Interventional nuclear image-guided HIFU is an attractive noninvasive option for the future.

Abstract
The optimal time interval between myomectomy and pregnancy is unclear and no specific guidelines exist. The aim of this review was to study the time interval from myomectomy to pregnancy and the occurrence of uterine rupture after myomectomy. Randomized controlled trials, cohort studies and retrospective studies were used to assess the primary objective, and case reports, cases series or letters to the editor for the secondary objective. Only articles reporting myomectomy performed via the vaginal route, laparotomy, laparoscopy or robot-assisted surgery were selected for inclusion. Among 3852 women who wanted to become pregnant after the surgery, 2889 became pregnant, accounting for 3000 pregnancies (77.9%) and 2097 live births (54.4%). Mean time between myomectomy and pregnancy was estimated at 17.6 months (SD 9.2) for 2451 pregnant women. Among 1016 women, a third were advised to delay attempting to conceive for between 3 and 6 months and another third for between 6 and 12 months. A total of 70 spontaneous uterine ruptures with a mean gestational age of 31 weeks at occurrence were identified. No linear relationship was found between gestational age at the event and time interval from myomectomy to conception (P = 0.706). There are insufficient data to advise a minimal time interval between myomectomy and conception.

Front Oncol 2021; 11:600800. [PMID: 33767979 PMCID: PMC7985460 DOI: 10.3389/fonc.2021.600800] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Accepted: 02/04/2021] [Indexed: 12/19/2022] Open
Abstract
Background: Uterine fibroids are common benign tumors among premenopausal women. High- intensity focused ultrasound (HIFU) is an emerging non-invasive intervention which uses the high-intensity ultrasound waves from ultrasound probes to focus on the targeted fibroids. However, the efficacy of HIFU in comparison with that of other common treatment types in clinical procedure remains unclear. Objective: To investigate the comparative effectiveness and safety of HIFU with other techniques which have been widely used in clinical settings. Methods: We searched the Cochrane Central Register of Controlled Trials, PubMed, EMBASE, Cumulative Index to Nursing & Allied Health Literature, Web of Science, ProQuest Nursing & Allied Health Database, and three Chinese academic databases, including randomized controlled trials (RCTs), non-RCTs, and cohort studies. The primary outcome was the rate of re-intervention, and the GRADE approach was used to interpret the findings. Results: About 18 studies met the inclusion criteria. HIFU was associated with an increased risk of re-intervention rate in comparison with myomectomy (MYO) [pooled odds ratio (OR): 4.05, 95% confidence interval (CI): 1.82–8.9]. The results favored HIFU in comparison with hysterectomy (HYS) on the change of follicle-stimulating hormone [pooled mean difference (MD): −7.95, 95% CI: −8.92–6.98), luteinizing hormone (MD: −4.38, 95% CI: −5.17−3.59), and estradiol (pooled MD: 43.82, 95% CI: 36.92–50.72)]. HIFU had a shorter duration of hospital stay in comparison with MYO (pooled MD: −4.70, 95% CI: −7.46−1.94, p < 0.01). It had a lower incidence of fever (pooled OR: 0.15, 95% CI: 0.06–0.39, p < 0.01) and a lower incidence of major adverse events (pooled OR: 0.04, 95% CI: 0.00–0.30, p < 0.01) in comparison with HYS. Conclusions: High-intensity focused ultrasound may help maintain feminity and shorten the duration of hospital stay. High-quality clinical studies with a large sample size, a long-term follow-up, and the newest HIFU treatment protocol for evaluating the re-intervention rate are suggested to be carried out. Clinical decision should be based on the specific situation of the patients and individual values.

J Minim Invasive Gynecol 2020; 28:218-227. [PMID: 33197612 DOI: 10.1016/j.jmig.2020.11.004] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 11/07/2020] [Accepted: 11/10/2020] [Indexed: 02/06/2023]
Abstract
OBJECTIVE This study aimed to compare the clinical effects of uterine artery embolization (UAE) with those of high-intensity focused ultrasound (HIFU) ablation for the treatment of symptomatic uterine myomas. DATA SOURCES We searched PubMed, EMBASE, Web of Science, Cochrane Library, Google Scholar, and ClinicalTrials.gov for studies from January 2000 to August 2020. Related articles and relevant references of the included studies were also searched. METHODS OF STUDY SELECTION Two researchers independently performed the data selection. We included comparative studies that compared the clinical outcomes of UAE with those of HIFU ablation in women with myomas. TABULATION, INTEGRATION, AND RESULTS We assessed the study quality using the Cochrane Handbook for Systematic Reviews of Interventions for evaluating the risk of bias. Two independent researchers performed the article selection according to the screening criteria and rated the quality of evidence for each article. We calculated pooled mean difference with 95% confidence interval (CI) for continuous data and relative risk (RR) with 95% CI for dichotomous data. The systematic review registration number is CRD42020199630 on the International Prospective Register of Systematic Reviews. A total of 7 articles (5 trials), involving 4592 women with symptomatic uterine myomas, were included in the meta-analysis. Compared with the HIFU ablation group, the decrease in "uterine fibroid symptom" scores as well as the increase in quality-of-life scores at the time of follow-up were higher in the UAE group, with overall mean difference 19.54 (95% CI, 15.21-23.87; p <.001) and 15.72 (95% CI, 8.30-23.13; p <.001), respectively. The women in the UAE group had a significantly lower reintervention rate (RR 0.25; 95% CI, 0.15-0.42; p <.001). The women undergoing UAE had a significantly lower pregnancy rate than those undergoing HIFU ablation (RR 0.06; 95% CI, 0.01-0.45; p = .006). The difference in the incidence of adverse events between the 2 groups was not statistically significant (p = .53). CONCLUSION Compared with HIFU ablation, UAE provided more significant alleviation of symptoms and improvement in quality of life, lower postoperative reintervention rate, and lower pregnancy rate for women with uterine myomas. However, we cannot conclude that HIFU ablation is more favorable for desired pregnancy than UAE because of the confounding factors.
