Comparison of Severity of Genitourinary Syndrome of Menopause Symptoms After Carbon Dioxide Laser vs Vaginal Estrogen Therapy: A Systematic Review and Meta-analysis

Energy-based interventions for genitourinary syndrome of menopause: a systematic review of randomized controlled trials and prospective observational studies

IMPORTANCE

Hormone treatments for genitourinary syndrome of menopause (GSM) symptoms have limitations. There is interest in nonhormone therapies, including energy-based interventions. Benefits and harms of energy-based interventions are not currently well known.

OBJECTIVE

The aim of this study was to assess the benefits and harms of energy-based therapies (eg, CO 2 laser, Er:YAG laser, and radiofrequency) for GSM. Outcomes of interest are the eight "Core Outcomes in Menopause" and include the following: dyspareunia, vulvovaginal dryness, vulvovaginal discomfort/irritation, dysuria, change in most bothersome symptom, quality of life, treatment satisfaction, and treatment adverse effects.

EVIDENCE REVIEW

Eligible studies included English language randomized controlled trials (RCT) or prospective observational studies of energy-based treatments with ≥8 weeks follow-up in postmenopausal women with ≥1 GSM symptom and studies of any design reporting adverse effects ≥12 months postintervention. Ovid/MEDLINE, Embase, and CINAHL were searched from inception to December 11, 2023 using vocabulary and natural language terms, along with free-text words. Two authors extracted data and assessed the quality of included studies.

FINDINGS

We identified 32 unique studies (16 RCT; 1 quasi-RCT; 15 nonrandomized). Ten RCT and the quasi-RCT were rated low to moderate risk of bias (RoB) and underwent data extraction. Included studies evaluated CO 2 laser (k = 7), Er:YAG laser (k = 3), or radiofrequency and CO 2 laser (k = 1). CO 2 laser compared with sham (k = 4) may result in little to no difference in dysuria, dyspareunia, or quality of life (low certainty of evidence [COE]). CO 2 laser compared with vaginal conjugated estrogens cream (k = 2) may result in little to no difference in dyspareunia, dryness, discomfort/irritation, dysuria, or quality of life (low COE). Treatment effects on all other outcomes and effects of Er:YAG laser or radiofrequency on any outcome are very uncertain (very low COE). Studies noted few adverse events and no serious adverse events.

CONCLUSIONS AND RELEVANCE

CO 2 laser resulted in little to no difference in outcomes compared with sham or vaginal estrogen; the evidence is very uncertain on the effect of energy-based interventions versus all other comparators for all other outcomes. Adverse event reporting was limited. There is a need for further evidence assessing energy-based interventions.

Use of radiofrequency ablation of the vaginal canal for genitourinary syndrome of menopause

BACKGROUND

Genitourinary syndrome of menopause (GSM) is a prevalent condition with a constellation of symptoms including burning, dryness, dyspareunia, and irritative lower urinary tract symptoms that result from vulvovaginal atrophic changes. Though hormonal therapy is a mainstay of treatment in GSM, some patients may pursue nonhormonal therapies.

AIM

To determine the efficacy of radiofrequency ablation of the vaginal canal with the MorpheusV applicator in reducing the symptoms of GSM.

METHODS

We conducted a multicenter prospective case series of women with GSM as confirmed by Vaginal Health Index Score (VHIS). Subjects received 3 treatments of radiofrequency ablation ~4 weeks apart with follow-up to 6-month posttreatment.

OUTCOMES

The primary endpoint was VHIS at 6-month posttreatment. Secondary endpoints were VHIS at 3 months, Visual analog scale (VAS) pain with each treatment, 3- and 6-month measurements of urogenital distress inventory-6 (UDI-6), and female sexual function index (FSFI) questionnaires.

RESULTS

From 2021 to 2023, 71 women were enrolled in the study with 51 followed to the 6-month follow-up time point. Treatments were found to be low in VAS pain score with mean values of 2.13 ± 2.1, 2.55 ± 2.38, and 2.18 ± 2.14 at treatments 1, 2, and 3 respectively. An improvement in VHIS score was seen from baseline to 3 months after the last treatment (15.00 ± 5.37 vs. 19.62 ± 4.44) and sustained at 6 months (20.23 ± 4.12) (P < .001). Significant improvements in both UDI-6 and FSFI were also noted. Between baseline and 6 months after treatment (FSFI: 18.81 ± 9.57 vs. 22.81 ± 10.34, P < 0.001; UDI-6: 39.58 ± 15.98 vs. 22.42 ± 14.03, P < 0.001). No adverse events were encountered by any subject during this study.

CLINICAL IMPLICATIONS

A therapy that is safe and effective in the treatment of both GSM and lower urinary tract symptoms without the use of hormonal methods is clinically impactful for the many patients who cannot receive or do not desire to receive these medications.

STRENGTHS AND LIMITATIONS

Strengths of this study include the utilization of 3 treatment sessions, with follow-up of subjects to 6-month posttreatment with a comprehensive assessment of patient symptoms. Limitations include the unblinded nature of the study and the lack of a comparator group.

CONCLUSION

The data from this study suggests that radiofrequency ablation of the vaginal canal by the MorpheusV applicator is a safe and effective intervention for GSM. It also shows subjective improvements in stress urinary incontinence, urge urinary incontinence, and sexual function.

Experience in the Management of Genitourinary Syndrome of Menopause With Fractional CO2 Laser at Dr. Alejandro Dávila Bolaños Military Teaching Hospital in Nicaragua

OBJECTIVE

We evaluated the quality of life improvements in patients with genitourinary syndrome of menopause (GSM) who received fractional CO2 laser therapy at the Gynecology-Obstetrics Department of "Dr. Alejandro Dávila Bolaños" Military School Hospital (HMADB) in Managua, Nicaragua, from June 2022 to October 2023.

MATERIALS AND METHODS

This descriptive cross-sectional study included 25 GSM patients with contraindications or insufficient response to local estrogen therapy. Each patient received two sessions of fractional CO2 laser therapy targeting the vaginal canal, vestibule, and labia minora, with a six-week interval between treatments. The Vulvovaginal Symptom Questionnaire (VSQ) was administered pre-treatment and at three and six months post-treatment. Statistical analysis was performed using the paired t-test.

RESULTS

Most patients were between 56 and 68 years of age (80%), and 56% were in active sexual relationships. Prior to CO2 laser therapy, 100% of participants reported vulvar symptoms, 92% experienced impacts on daily life, and 72% had difficulties in sexual life. Six months post-treatment, these percentages dropped to 40%, 16%, and 8%, respectively. Overall, 52% of patients became asymptomatic, while 48% reported mild symptoms. Paired t-test analysis indicated statistically significant improvements (p < 0.05) between pre- and post-treatment scores. Mild and transient adverse effects included pruritus (40%), pain (28%), dyspareunia (24%), and erythema (16%).

CONCLUSION

Fractional CO2 laser therapy is a safe and effective non-hormonal option for GSM management, with minimal and transient side effects, providing a valuable alternative for patients who cannot use estrogen-based treatments.

Should I stay for local hormone therapy or should I go for radiofrequency to treat vulvovaginal atrophy? A patient preference trial

OBJECTIVE

To compare patient satisfaction rate in postmenopausal women who chose dynamic quadripolar radiofrequency or topical estrogens as their preferred treatment for genitourinary syndrome of menopause.

METHODS

Patients were divided into two groups according to their preference: one was treated with estrogen therapy (ET) and the other with dynamic quadripolar radiofrequency treatment (RF). All patients included fulfilled a series of validated questionnaires, at baseline and at the 6-mo follow-up, in order to evaluate the discomfort degree associated with the presence of vulvovaginal atrophy and the impact of the reported symptoms on QoL and sexuality.

RESULTS

After propensity score matching, the proportion of women considering themselves satisfied with their genital health conditions was extremely small at study entry (5.2% of the RF group and 6.9% of the ET group), while at a 6-mo follow-up, it increased to 46.7% and 46.6%, respectively. No statistically significant between-group differences were found regarding mean numerical rating scale scores for dryness and dyspareunia at follow-up (5.6 ± 2.6 vs 5.3 ± 2.3, P = 0.5; and 2.9 ± 2.5 vs 3.0 ± 2.7, P = 0.46). At 6-mo follow-up, we observed no statistically significant differences between the two groups regarding the other items evaluated. RF treatment was overall well tolerated.

CONCLUSION

The use of quadripolar radiofrequency devices seems effective, but it is not associated with better clinical outcomes compared with topical hormone treatment, which is a substantially cheaper and more convenient treatment for genitourinary syndrome of menopause. Therefore, we suggest limiting the use of dynamic quadripolar radiofrequency selectively when topical estrogens are not effective, not tolerated, or contraindicated.

Physical energies for the management of genitourinary syndrome of menopause: An overview of a systematic review and network meta-analysis

BACKGROUND

Energy-based devices (laser and radiofrequency) have been used to treat genitourinary syndrome of menopause (GSM).

OBJECTIVES

To evaluate the efficacy and safety of physical energy use in managing GSM symptoms.

SEARCH STRATEGY

Five databases were searched from inception to December 2022. Language restrictions were not imposed.

SELECTION CRITERIA

We included all Cochrane and non-Cochrane systematic reviews with or without meta-analyses that described postmenopausal women with symptoms of GSM treated with physical energy.

DATA COLLECTION AND ANALYSIS

We performed a network meta-analysis using frequentist methods to calculate standardized mean differences (SMDs) and their corresponding 95% confidence intervals (CIs). Methodological and reporting quality were assessed using the Assessment of Multiple Systematic Reviews (AMSTAR 2).

MAIN RESULTS

Nine reviews were included in the overview, six of which were meta-analyses. Four randomized controlled trials, representing 218 participants and nine different study arms, met the criteria for inclusion in our component network meta-analysis. Confidence in review findings was low in six reviews and critically low in three. Our network meta-analysis results showed that premarin (SMD 2.60, 95% CI 7.76-3.43), conjugated estrogens (SMD 2.13, 95% CI 1.34-2.91), carbon dioxide laser (SMD 1.71, 95% CI 1.10-2.31), promestriene (SMD 1.41, 95% CI 0.59-2.24), and vaginal lubricant (SMD 1.37, 95% CI 0.54-2.20) were more effective than sham for reducing sexual dysfunction, with a consequent increase in Female Sexual Function Index (FSFI). Two studies showed a high risk of bias, owing to a lack of blinding.

CONCLUSION

Several gaps in the use of physical energy for managing GSM still need to be addressed. The small number of blind clinical trials made the results fragile.

Vaginal dryness: a review of current understanding and management strategies

The issue of vaginal dryness in genitourinary syndrome of menopause (GSM) and its pervasive impact on women's quality of life is often overlooked. Extensive surveys conducted worldwide reveal limited understanding of vaginal dryness among public and health-care providers. Physician knowledge on menopause medicine varies globally, highlighting the need for standardized training. Effective communication between physicians and patients plays a crucial role in diagnosing and treating GSM symptoms. There are multiple treatment options to improve vaginal lubrication, including hormonal and non-hormonal therapies, along with lifestyle modifications. Tailoring treatments to individual patient preferences is crucial for compliance. Overall, GSM is multifaceted, from the prevalence of vaginal dryness to the nuances of treatment preferences. The urgency of widespread education and awareness of this matter must be underscored to meet the aim of enhancing the well-being and quality of life for women.

Laser therapy for genitourinary syndrome of menopause: systematic review and meta-analysis of randomized controlled trial

Objective

This meta-analysis of randomized controlled trials (RCTs) aimed to update evidence on the effectiveness and safety of laser therapy for treating genitourinary syndrome of menopause (GSM).

Data sources

Manuscripts published until May 2023 were systematically searched in PubMed; Embase; Scopus; Web of Science; CENTRAL; CINAHL; and clinical trial databases (www.trialscentral.org, www.controlled-trials.com, and clinicaltrials.gov), with no language and year of publication restriction.

Studies selection

RCTs with women diagnosed with GSM, and the intervention was vaginal laser therapy (CO2-laser or Er: YAG-laser) comparing with placebo (sham therapy), no treatment or vaginal estrogen therapy.

Data collection

Two authors evaluated the publications for inclusion based on the title and abstract, followed by reviewing the relevant full-text articles. Disagreements during the review process were addressed by consensus, with the involvement of a third author.

Data synthesis

Twelve RCTs, representing a total of 5147 participants, were included in this review. Vaginal health index (VHI) significantly improved in the carbon dioxide laser (CO2-laser) therapy group (MD=2.21; 95% CI=1.25 to 3.16), while dyspareunia (MD=-0.85; 95% CI=-1.59 to -0.10), dryness (MD=-0.62; 95% CI=-1.12 to -0.12) and burning (MD= -0.64; 95% CI=-1.28 to -0.01) decreased. No serious adverse effects were reported.

Conclusion

CO2-laser increases VHI score and decreases dyspareunia, dryness and burning, especially when compared to sham-laser. However, the certainty of the evidence is low, thus preventing the recommendation of laser therapy for GSM management.

CO2 Laser versus Sham Control for the Management of Genitourinary Syndrome of Menopause: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

In the context of the menopausal transition, genitourinary syndrome of menopause (GSM) refers to a range of genitourinary symptoms, from vaginal dryness to dysuria and urinary urgency. While hormonal treatments are standard, their associated side effects have driven the exploration of alternatives like vaginal CO2 laser. We aimed to evaluate the randomized controlled trials (RCTs) comparing vaginal CO2 laser treatment for GSM to sham controls. This systematic review sourced four electronic databases until June 2023. The analysis incorporated seven RCTs with 407 women. The CO2 laser and sham control were comparable for most parameters, including the female sexual function index (FSFI) and visual analogue scale (VAS) for dyspareunia, vaginal health index, pH, and patient satisfaction. However, the CO2 laser group showed significant improvement in the vaginal assessment scale for GSM symptoms. Sensitivity analyses revealed that parameters like FSFI showed significant differences in favor of CO2 laser group upon the exclusion of specific studies. In conclusion, vaginal CO2 laser therapy emerges as a promising alternative for GSM management, especially for most bothersome GSM symptoms; however, the need for further well-designed RCTs remains to validate its broad safety and efficacy.

Laser and radiofrequency for treating genitourinary syndrome of menopause in breast cancer survivors: a systematic review and meta-analysis protocol

INTRODUCTION

Breast cancer survivors (BCSs) experience more severe symptoms of genitourinary syndrome of menopause (GSM) than healthy postmenopausal women. As hormonal therapy with oestrogen should be avoided in BCSs, finding an effective and safe therapy to address vaginal symptoms and sexual dysfunction is urgently needed. Physical methods may be promising alternatives for the specificities of this group of women. This review aims to evaluate the efficacy and safety of physical methods (laser and radiofrequency) for treating GSM in BCSs.

METHODS AND ANALYSIS

The PubMed, Embase, Web of Science, SciELO, LILACS, Scopus, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov databases will be searched. A search strategy was developed to retrieve clinical trials that evaluate the efficacy and safety of any physical method (laser or radiofrequency) used for GSM in BCSs. No date or language restrictions will be imposed. Two authors will independently select studies by title, abstract and full text to meet the inclusion criteria. Data will be extracted, and the risk of bias will be evaluated using the Cochrane risk-of-bias tool (RoB 2). Review Manager 5.4.1 will be used for data synthesis. The Grading of Recommendations, Assessment, Development and Evaluation will be used to assess the strength of the evidence.

ETHICS AND DISSEMINATION

This study reviews the published data; thus, obtaining ethical approval is unnecessary. The findings of this systematic review will be published in a peer-reviewed journal.

Genitourinary Syndrome of Menopause in Breast Cancer Survivors: Current Perspectives on the Role of Laser Therapy

Genitourinary syndrome of menopause (GSM) is a frequent consequence of iatrogenic menopause or anti-estrogenic adjuvant therapies in breast cancer survivors (BCSs). GSM may profoundly affect sexual health and quality of life, and a multidimensional unique model of care is needed to address the burden of this chronic heterogeneous condition. Severe symptoms may be insufficiently managed with non-hormonal traditional treatments, such as moisturizers and lubricants, recommended as the first-line approach by current guidelines, because concerns exist around the use of vaginal estrogens, particularly in women on aromatase inhibitors (AIs). Vaginal laser therapy has emerged as a promising alternative in women with GSM who are not suitable or do not respond to hormonal management, or are not willing to use pharmacological strategies. We aim to systematically review current evidence about vaginal laser efficacy and safety in BCSs and to highlight gaps in the literature. We analyzed results from 20 studies, including over 700 BCSs treated with either CO2 or erbium laser, with quite heterogeneous primary outcomes and duration of follow up (4 weeks-24 months). Although evidence for laser efficacy in BCSs comes mostly from single-arm prospective studies, with only one randomized double-blind sham-controlled trial for CO2 laser and one randomized comparative trial of erbium laser and hyaluronic acid, available data are reassuring in the short term and indicate effectiveness of both CO2 and erbium lasers on the most common GSM symptoms. However, further studies are mandatory to establish long-term efficacy and safety in menopausal women, including BCSs.

The yin and yang of GSM and low sexual desire

Numerous surveys have documented that sexuality and/or sexual activity is important to women at all stages of adulthood, including postmenopause. Genitourinary syndrome of menopause (GSM) and hypoactive sexual desire disorder (HSDD) are common disorders in postmenopausal women and may co-occur. Both are often undiagnosed due to a lack of knowledge of the disorder, health-care professional discomfort in discussing sexual problems or a lack of routine screening. It is incumbent upon health-care professionals to identify and differentiate these conditions in women through a biopsychosocial assessment, and may require a focused physical examination. Numerous treatments, both non-pharmacologic and pharmacologic, are available to address GSM and HSDD.

Emerging Use of Vaginal Laser to Treat Genitourinary Syndrome of Menopause for Breast Cancer Survivors: A Review

Breast cancer treatment, such as chemotherapy and endocrine therapy, can cause earlier and more sudden menopausal symptoms. Genitourinary syndrome of menopause (GSM) is one of the most bothersome side effects of breast cancer treatment, resulting in sexual dysfunction and impaired quality of life. GSM includes genital, urinary, and sexual symptoms. However, alleviating symptoms of GSM for breast cancer survivors may be challenging due to ineffectiveness, contraindications, and low adherence to treatment. The most recent data show the feasibility and safety of vaginal laser to treat GSM for breast cancer survivors. This narrative review provides the aspects of GSM in breast cancer patients, putting the focus on the efficacy and safety of vaginal laser therapy.
