Medical or surgical management of fibroids? An internet survey of gynecologists’ views

Contemporary approaches in the management of uterine leiomyomas

BACKGROUND

Leiomyomas (fibroids), the most common benign solid tumours in females, originate from the myometrium and are associated with poor quality of life for patients. The current management of uterine leiomyomas mainly includes surgical interventions such as hysterectomy and myomectomy, either by laparoscopy or laparotomy, which have several complications and are not ideal for preserving fertility. Therefore, there is a need to develop or repurpose medical treatments that do not require surgical intervention.

OBJECTIVE

Many drugs are used to treat the symptoms associated with uterine fibroids. The main objective of this systematic review is to give an up-to-date account of potential pharmacological agents (non-surgical methods) for the management of uterine leiomyomas.

SEARCH STRATEGY

PubMed was searched for scientific and clinical literature using the keyword 'uterine fibroids' along with the drug names described in each section. For example, 'uterine fibroids' and 'ulipristal acetate' were the keywords used to search for literature on ulipristal acetate (UPA).

RESULTS

Various preclinical and clinical studies have shown that some drugs and herbal formulations exhibit activity in the management of uterine leiomyomas. Recent studies found that drugs such as UPA, elagolix, EC313, asoprisnol, nutritional supplements and herbal preparations were helpful in treating the symptoms associated with uterine leiomyomas.

CONCLUSION

Many drugs show efficacy in patients with symptomatic uterine fibroids. UPA is one of the most studied and prescribed medicines for uterine fibroids; however, its usage has been restricted due to a few recent incidences of hepatic toxicity. Herbal drugs and natural supplements have also shown promising effects on uterine fibroids. The synergistic effects of nutritional and herbal supplements have been reported in certain cases, and should be studied in detail. Further research is warranted to identify the mode of action of the drugs, and to determine the precise conditions that would explain the causes of toxicity in some patients.

Evidence-Based Management of Uterine Fibroids With Botanical Drugs-A Review

Uterine fibroids (UFs) are a common benign gynecological tumor that affect the majority of women over their lifetime. Several pharmacological agents are available to reduce the size of fibroids and ameliorate the symptoms of UF. However, these drugs are expensive and are usually associated with profound side effects. Thus, botanical drugs are gaining attention in this era due to their cost effectiveness with a comparable and more potent therapeutic efficacy while demonstrating lesser adverse effects. The objective of this review is to summarize the available information on the mechanism of various botanical drugs and polyherbal formulations with anti-uterine fibroid activity. A systematic search was performed on botanical drugs with anti-uterine fibroid activity using several search engines, which include PubMed, Google Scholar, and Science Direct. Based on the literatures identified, a total of five botanical drugs and three polyherbal formulations were included and discussed in this review, which yields useful information regarding the mechanism of different botanical drugs and polyherbal formulations in exerting anti-uterine fibroid activity for its potential use as an alternative treatment choice for uterine fibroids.

Multidisciplinary management to optimize outcome of ultrasound-guided high-intensity focused ultrasound (HIFU) in patients with uterine fibroids

Little is known about the specific anaesthesiological and multidisciplinary management of high-intensity focused ultrasound (HIFU) in uterine fibroids. This observational single-center study is the first reporting on an interdisciplinary approach to optimize outcome following ultrasound (US)-guided HIFU in German-speaking countries. A sample of forty patients with symptomatic uterine fibroids was treated by HIFU. Relevant treatment parameters such as total treatment time for intervention, anaesthesia, and sonication time as well as total energy, body temperature, peri-interventional medication and complications were analyzed. Interventional variables did not correlate significantly either with opioid dose or with body temperature. The average fibroid volume reduction rate was 37.8% ± 23.5%, 48.5% ± 22.0% and 70.2% ± 25.5% after 3, 6 and 12 months, respectively. No major anaesthesiological complications occurred apart from an epileptic seizure prior to HIFU treatment in one patient. Peri-procedural hyperthermia (> 37.5 °C) occurred in two patients. Post-procedural two patients experienced a sciatic nerve irritation up to one year; one patient with very large treated fibroid experienced strong short-lasting post-procedural pain. There were two complication-free pregnancies of HIFU-treated patients. Multidisciplinary management is crucial to optimize safety and outcome of US-guided HIFU for uterine fibroids. Peri-procedural pain and temperature management are critical points where an adequate collaboration between anesthesiologist and interventionalist is mandatory.

Suspension of ulipristal acetate for uterine fibroids during ongoing EMA's review of liver injury risk: Unfortunate timing during the Covid-19 pandemic!

Objective

EMA decided that with ulipristal acetate (UPA) treatment for uterine fibroids, should be discontinued due to the associated risk of hepatic failure, We analyzed whether the risk of recurrent symptoms due to fibroids may lead to an increased risk of Covid -19 infection and death, that would exceed the former risk of hepatic failure and transplantation.

Study design, size, duration

We used a Markov model to generate probabilities.

Participants/materials, setting, methods

There are currently about 36,250 treated patients in Europe. We estimated bleeding probabilities, while using or discontinuing UPA, which may induce a need of medical or surgical management in symptomatic patients, and increase the risk of acquiring a Covid-19 infection, and die from it. We also estimated the risk of suffering a hepatic failure and hepatic transplantation.

Main results and the role of chance

Based on our assumptions, ceasing UPA during a Covid 19 pandemic may be associated with a fatality ratio between 4 and 18, due to the Pandemic, whereas pursuing UPA would be associated with a fatality rate due to the pandemic between 1–2, and an added fatality rate due to hepatic impairment of 1. The added risk of stopping UPA may range between 2 and 15 additional deaths.

Our calculations suggest that the decision to stop UPA in the middle of the Covid- 19 pandemic may be untimely, since it may result in an increased risk of Covid-19 infection, due to the recurrence of symptoms and the need for medical and surgical treatment.

Wider implications of the findings

A decision, like the one EMA took need to be taken in a wider health context of a population, than simply analyzing its role as regulating agent for medications.

Guizhi Fuling Wan for uterine fibroids: A systematic review of in vivo studies

ETHNOPHARMACOLOGICAL RELEVANCE

The therapeutic effects of Guizhi Fuling Wan (GFW) on uterine fibroids have been tested on various animal models, but to date, the findings of these studies have not been comprehensively synthesised. This study aimed to evaluate the preclinical effects of GFW on uterine fibroids in different animal models.

MATERIALS AND METHODS

Twenty databases were searched from their earliest recorded publications to March 2019 to identify in vivo studies of non-modified GFW compared with no treatment for animal models with uterine fibroids. The methodological quality was assessed using the ARRIVE guidelines. Two groups of outcome measures were evaluated: fibroid characteristics (uterine weight, coefficient or smooth muscle thickness) and sex hormones indexes (oestradiol, progesterone or the gene expression of their receptors).

RESULTS

A total of 21 studies (22 experiments) involving 461 female animals met the eligibility criteria. The quality of the included studies scored at 14.24 ± 1.00 out of 20. Four animal species were used and induced by oestrogen or oestrogen combined with progesterone, including guinea pig (n = 20), rats (n = 385, SD and Wister) and mice (n = 56). Overall, the available evidence suggests that GFW has potentially beneficial effects over placebo on both fibroid characteristics and sex hormones in SD rats (except progesterone), Wister rats (except progesterone receptor [PR] gene expression) and ICR mice (except PR gene expression). GFW appears to reduce uterine weight and smooth muscle thickness in the guinea pig, but no data on sex hormone index was available.

CONCLUSION

Noting the unevenly distributed covariates of animal model types, experimental evidence suggested that GFW may be a promising intervention for the management of uterine fibroids in animal models. Future natural product studies should be optimised by reporting the voucher specimen. More studies on composition and providing evidence of the involvement of relevant cell signalling pathways are required.

Ulipristal acetate for pre-operative management of uterine fibroids: Modeling outcomes and costs

OBJECTIVES

The aim of this study was to evaluate the pharmacoeconomic profile in Italy of preoperative treatment with ulipristal acetate at the dose of 5 mg/day for 13 weeks in comparison with placebo prior to surgical management of symptomatic uterine fibroids.

STUDY DESIGN

The pharmacoeconomic analysis was based on the calculation of incremental cost-effectiveness ratio (ICER). Effectiveness data were derived from the randomized-controlled trial PEARL-1, whilst costs data were retrieved from the published literature. A Markov model was employed to simulate the pattern of costs and two univariate sensitivity analyses tested the robustness of the results.

RESULTS

In comparison with placebo, ulipristal acetate 5 mg for presurgical therapy was estimated to be associated with an incremental cost of €351 per patient. Costs per patient were €3836 for ulipristal acetate vs €3485 for placebo. The incremental effectiveness was 0.01931 QALYs per patient (around 7 quality-adjusted days per patient). Hence, the cost effectiveness ratio was calculated to be €18,177 per QALY gained.

CONCLUSIONS

Preoperative use of ulipristal acetate 5 mg in patients with uterine fibroids has a favourable pharmacoeconomic profile.

Current Practices for Treatment of Uterine Fibroids

The treatment of uterine fibroids depends on symptoms of patients, size of the fibroid, desire for future pregnancy, and preference of the treating gynecologist. The present study was undertaken to compare treatment preferences in women desirous and nondesirous of pregnancy by an experienced gynecologist in symptomatic uterine fibroids. Newer medical or minimally invasive treatment modalities are increasingly being used for the treatment of fibroids. However, conventional surgical treatment such as myomectomy and hysterectomy are still preferred by gynecologists.

Burden of uterine fibroids in Italy: epidemiology, treatment outcomes, and consumption of health care resources in more than 5,000 women

Background and purpose

Epidemiological studies on uterine fibroids (UFs) are mostly based on surveys or analyses of small samples of patients. In 50% of women, the quality of life is worsened by disease-related symptoms; furthermore, treatments imply a remarkable health care cost. The aim of this observational study was to analyze a large sample of Italian patients with UFs and to assess the epidemiology, the appropriateness of treatments, and the consumption of disease-related resources.

Methods

Data were collected through a data-linkage technique from five administrative databases. Women aged between 18 and 55 years and resident in three local health authorities (north–central–south Italy) were selected over the period from 1st January 2009 to 31st December 2015. The inclusion criteria were a surgical procedure with diagnosis of UFs or a pharmacological treatment with gonadotropin-releasing hormone (GnRH) analogs or ulipristal acetate. Besides the overall descriptive analysis, two comparisons were evaluated: surgery versus no surgery and treatment with GnRH analogs versus ulipristal acetate.

Results

A total of 5,665 women with UFs were selected from an overall population of 2,400,000 people. In the north, 73.6% of patients underwent surgery, as opposed to only 16.7% in the south; 70% of surgeries were hysterectomies. The average cost per patient was €3,249 (duration of follow-up = up to 7 years). The southern district had the highest number of drug prescriptions; in particular, 49% of patients took >10 packages of GnRH analogs.

Conclusion

This study is the first on this topic conducted in Italy using a large sample size. The analysis of resource consumption revealed a high heterogeneity in the choice of drug treatments by gynecologists (especially in the south); in the north, marked variations were seen in the rates of surgery. The long-term use of GnRH was inappropriate.

The use of selective progestin receptor modulators (SPRMs) and more specifically ulipristal acetate in the practice of gynaecology

This review discusses the development of selective progestin receptor modulators (SPRMs) for use in women's health and specifically the use of ulipristal acetate (UPA) as emergency contraception (EC) and as a treatment for symptomatic fibroids in women who want to preserve their fertility or avoid a hysterectomy. As an EC, UPA 30 mg should be recommended for women, within 102 h of unprotected intercourse. As a treatment of fibroids, UPA (5 mg daily dose) should be administered for periods of three months as a pre-surgical strategy, reducing bleeding and fibroid size and facilitating surgery. A proportion of these patients may even avoid surgery. Future developments will demonstrate whether UPA can be used for other indications such as endometriosis and breast cancer prevention or treatment.
