Non-extirpative Treatments for Uterine Myomas: Measuring Success

The challenge of FIGO type 3 leiomyomas and infertility: Exploring therapeutic alternatives amidst limited scientific certainties

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.

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.

Uterine Myoma Position-based Radiofrequency Ablation (UMP-b RFA): 36 months follow-up clinical outcomes

OBJECTIVE

To assess the efficacy of Uterine Myoma Position-based Radiofrequency Ablation (UMP-b RFA) at 36 months. An analysis of a new uterine fibroid ablation technique that allows personalized access of delivering radiofrequency energy (transvaginal, hysteroscopic or laparoscopic) based on myoma localization.

STUDY DESIGN

Prospective observational cohort study in a community-based secondary care medical center enrolled 61 premenopausal women with 112 symptomatic uterine myomas. 112 fibroids were ablated in 5 ways with single or combined accesses: 82 Vaginal Ultrasound (VU)-guided RFA, 19 Laparoscopic (L)-RFA, 5 Hysteroscopic (H)-RFA, 5 VU+H-RFA, and 1 VU+L-RFA. The primary endpoint of this study was to evaluate the 3-year clinical outcome of UMP-b RFA. The secondary endpoint was the possible identification of predictors of its success. The outcomes evaluated at 12, 24, and 36 months after UMP-b RFA were myoma size, type of symptomatology suffered, quality of life based on the "Uterine Fibroid Symptom and Quality of Life" questionnaire, and interviews on the degree of satisfaction with this surgery. The reintervention and complication rates were also recorded and analyzed.

RESULTS

Fibroids volume and diameter were significantly reduced by -90.2 % / -55.7 % at 36 months post-intervention (p < 0.001) and the reduction of Symptom Severity scores was -71.8 % three years after UMP-b RA (p < 0.001). The overall improvement in the quality of life was demonstrated by an increase in the Quality-of-Life score of + 26.0 % at the third follow-up (p < 0.001). 88.5 % of the patients interviewed would have the surgery done again if they went back in time. The reintervention rate was 10/61 (16.4 %): 3 hysterectomies, 3 myomectomies, 3 operative hysteroscopies and 1 VU-RFA reoperation. In this group of unsuccessful surgeries, the mean diameter of the dominant myomas was found to be greater than that of the successes (5.3 vs 4.4 cm.). Out of the 61 cases, no major complications occurred, and the 2 minor complications observed were self-limiting.

CONCLUSION

Uterine Myoma Position-based Radiofrequency Ablation is a safe, effective, and minimally invasive solution for the treatment of symptomatic fibroids. Indeed, these clinical outcome data at 36 months shows how UMP-b RFA can treat the symptomatology of uterine fibromatosis. Hysterectomies or myomectomies were successfully avoided in more than 80 % of women bearing myomas with an average diameter of less than 5 cm.

A Call-to-Action for Clinicians to Implement Evidence-Based Best Practices When Caring for Women with Uterine Fibroids

Uterine fibroids are common benign tumors that occur in up to 80% of women. Approximately half of the women affected experience considerable physical, psychological, and economic burdens and impact on quality of life due to symptoms such as heavy menstrual bleeding, pelvic pain, and infertility. Several medical and surgical options are available to treat uterine fibroids; however, healthcare providers may benefit from practical guidance in the development of individualized treatment plans based on a personalized approach. Medical treatments and minimally invasive procedures are generally preferred by most patients before considering more invasive, higher risk surgical interventions. In general, patient-centered, uterine-preserving procedures may be prioritized based on the patient’s goals and the clinical scenario. Occasionally, hysterectomy may be the preferred treatment option for some patients who require definitive treatment. This call-to-action highlights recent challenges to patient care, including radical shifts in physician–patient interactions due to the COVID-19 pandemic and recent changes to evidence-based, clinically approved therapies. This report also reviews contemporary recommendations for women’s health providers in the diagnosis and medical and surgical management of uterine fibroids. This call-to-action aims to empower healthcare providers to optimize the quality of care for women with uterine fibroids utilizing the best available evidence and best practices.

Radiofrequency Ablation of Uterine Fibroids and Pregnancy Outcomes: An Updated Review of the Literature

OBJECTIVE

To provide a systematic review of pregnancy outcomes after radiofrequency ablation of uterine fibroids.

DATA SOURCES

A literature search was conducted using PubMed, Cochrane Library, Scopus, Web of Science, and EMBASE, from database inception until October 2021.

METHODS OF STUDY SELECTION

Two reviewers conducted independent literature searches. Studies that met criteria based on title and abstract underwent full text review. Publications were included if they reported pregnancies and obstetric outcomes after laparoscopic or transcervical radiofrequency ablation (RFA) of fibroids.

TABULATION, INTEGRATION, AND RESULTS

405 publications were initially identified and screened, 39 underwent full text review, and 10 publications were ultimately included. There were 50 pregnancies reported among 923 RFA patients: 40 pregnancies after 559 laparoscopic RFAs and 10 pregnancies after 364 transcervical RFAs. The number of patients from these studies actively trying to conceive after RFA is unknown. Among the RFA patients who conceived, the average age at ablation was 37 years old (range 27 to 46 years). The majority of patients had between 1 and 3 fibroids ablated, and fibroid size ranged from less than 2 centimeters to 12.5 centimeters. There were 6 spontaneous abortions (12%) and 44 full-term pregnancies (88%), of which 24 were vaginal deliveries and 20 were cesarean deliveries. There were only 2 complications among 44 deliveries: 1 placenta previa that underwent an uncomplicated cesarean delivery and 1 delayed postpartum hemorrhage with expulsion of a degenerated myoma, with no long-term sequelae. There were no cases of uterine rupture, uterine window, or invasive placentation, and no fetal complications. The spontaneous abortion rate was comparable to the general obstetric population.

CONCLUSION

Almost all pregnancies after radiofrequency ablation of fibroids were full-term deliveries with no maternal or neonatal complications. These findings add to the literature that radiofrequency fibroid ablation may offer a safe and effective alternative to existing treatments for women who desire future fertility.

Network pharmacology evaluation of the active ingredients and potential targets of XiaoLuoWan for application to uterine fibroids

XiaoLuoWan (XLW) is a classical formula in traditional Chinese medicine (TCM) that has satisfactory therapeutic effects for uterine fibroids (UFs). However, its underlying mechanisms remain unclear. To elucidate the pharmacological actions of XLW in treating UFs, an ingredient–target–disease framework was proposed based on network pharmacology strategies. The active ingredients in XLW and their putative targets were obtained from the TCM systems pharmacology database and analysis platform (TCMSP) and Bioinformatics Analysis Tool for Molecular mechANism of Traditional Chinese Medicine (BATMAN-TCM) platforms. The known therapeutic targets of UFs were acquired from the DigSee and DrugBank databases. Then, the links between putative XLW targets and therapeutic UF targets were identified to establish interaction networks by Cytoscape. Finally, Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses of overlapping gene targets were performed in the STRING database and visualized in R software. In total, 9 active compounds were obtained from 74 ingredients, with 71 curative targets predicted in XLW. Moreover, 321 known therapeutic targets were closely related to UFs, with 29 targets overlapping with XLW and considered interacting genes. Pathway enrichment revealed that the calcium signaling pathway was significantly enriched and the mitogen-activated protein kinase (MAPK) signaling pathway, cAMP signaling pathway, cancer and vascular smooth muscle contraction pathways, cGMP-PKG signaling pathway, and AGE-RAGE signaling pathway were closely associated with XLW intervention for UFs. In conclusion, the network pharmacology detection identified 9 available chemicals as the active ingredients in XLW that may relieve UFs by regulating 29 target genes involved in the calcium signaling pathway, MAPK pathway and cAMP pathway. Network pharmacology analyses may provide more convincing evidence for the investigation of classical TCM prescriptions, such as XLW.
