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

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.

Practical Guidance on the Use of Vaginal Laser Therapy: Focus on Genitourinary Syndrome and Other Symptoms

Genitourinary syndrome of the menopause (GSM) is a chronic, often progressive condition, characterised by symptoms relating to oestrogen deficiency including; vaginal dryness, burning, itching, dyspareunia, dysuria, urinary urgency and recurrent urinary tract infections. GSM affects up to 70% of breast cancer survivors with a tendency to particularly severe symptoms, owing to the effects of iatrogenic menopause and endocrine therapy. Patients and clinicians can be reluctant to replace oestrogen vaginally due to fear of cancer recurrence. Vaginal laser is a novel therapy, which may become a valuable nonhormonal alternative in GSM treatment. There are currently 6 published studies regarding Erbium:YAG laser treatment for GSM, 41 studies regarding CO2 laser treatment for GSM and 28 studies regarding vaginal laser treatment for GSM in breast cancer survivors. Number of participants ranges from 12 to 645. The majority of studies describe a course of 3 treatments, but some report outcomes after 5. Significant improvements were reported in vaginal dryness, burning, dyspareunia, itch, Vaginal Health Index Scores (VHIS), Quality of Life, and FSFI (Female Sexual Function Index). Most studies reported outcomes at short-term follow-up from 30 days to 12 months post-treatment. Few studies report longer-term outcomes with conflicting results. Whilst some studies suggest improvements are sustained up to 24 months, others report a drop-off in symptom improvement at 12-18 months. Patient satisfaction ranged from 52% to 90% and deteriorated with increasing time post-procedure in one study. The findings in this review must be validated in robust randomised sham-controlled trials of adequate power. There remain a number of unanswered questions in terms of which laser medium to use, optimal device settings, ideal interval between treatments, pre-treatment vaginal preparation, as well as safety and efficacy of repeated treatments long term. These issues could be addressed most efficiently with a mandatory registry of vaginal laser procedures.

Safety and efficacy of non-ablative CO2 laser treatment of vulvo-vaginal atrophy in women with history of breast cancer

PURPOSE

Breast cancer survivors (BCS) suffer severe vulvo-vaginal atrophy (VVA) and some of the most effective therapies are contraindicated. In literature we have no data about the non-ablative CO2 laser on these women. The aim of this study was to examine its efficacy, safety and acceptability in BCS.

MATERIALS AND METHODS

The enrolled women underwent 3 sessions of laser therapy (t0, t1, t2) and a one-month follow up examination (t3). At each time point we measured objective signs of VVA via VHI (Vaginal Health Index) and VuHI (Vulvar Health Index) and subjective parameters (Dryness, Burning, Itching, Dysuria) via visual analog scales (VAS). In sexually active women we evaluated the sexual function with FSFI (Female Sexual Function Index), FSDS (Female Sexual Distress Score) scores and MENQOL (menopause quality of life questionnaire).

RESULTS

We enrolled 26 BCS. The mean VHI, VuVHI, dryness and burning VAS scores improved significantly and this improvement was not influenced by the initial VVA grade. MENQOL sexual domain, Lubrication, Orgasm and Pain domains and FSFI total score improved significantly, while Desire, Arousal and Satisfaction domains of FSFI and FSDS did not. At t0 women using Aromatase Inhibitors suffered more severe vaginal dryness than women using Tamoxifen or no therapy, but the three subgroups improved without differences. No adverse event and minimum discomfort were reported.

CONCLUSIONS

The non-ablative CO2 laser is a safe and effective treatment of VVA and has positive effects on sexual function in BCS regardless the use of adjuvant therapies and the initial grade of VVA.

Genitourinary Syndrome of Menopause in Cancer Survivors

Genitourinary syndrome of menopause (GSM) encompasses the symptoms of estrogen deprivation in the vaginal, vulva, and bladder areas. Because many cancer treatments induce a hypoestrogenic state, GSM is common in cancer survivors. The number of cancer survivors is increasing, and the unique aspects of GSM management for cancer survivors, such as the safety of hormonal therapies, is important to understand. In this review, we cover important considerations in the assessment of GSM; nonpharmacologic, behavioral, integrative, pharmacologic, and medical device treatments for GSM: the unique considerations in GSM by cancer treatment modality; bladder manifestations of GSM; and GSM in specific populations.

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.

Estrogen deprivation effects of endocrine therapy in breast cancer patients: Incidence, management and outcome

Endocrine therapy is one of the standard adjuvant treatments to reduce the risk of recurrence and mortality in patients with hormone receptor positive early breast cancer. Despite its proven efficacy, ET side effects, which persist over time even if low grade, may deteriorate quality of life. During follow-up visits, emphasis is generally placed on the risk of disease recurrence, while the topic of ET side effects is commonly neglected and discussed only briefly. This could lead to poor adherence to therapy and early treatment discontinuation, resulting in worse survival outcomes. The aim of this review is to provide an overview of the available evidence on the incidence and reporting of ET-related side effects (including vasomotor symptoms, musculoskeletal disorders and genitourinary syndrome of menopause, as well as fatigue, psychological and ocular disorders, dysmetabolic effects and loss of bone density) and of the pharmacological and non-pharmacological strategies available to mitigate symptom burden.

The Effect of Radiofrequency Therapy on Sexual Function in Female Cancer Survivors (Gynecologic and Breast) and Non-cancer Menopausal Women: A Single-Arm Trial

Introduction: Up to 90% of postmenopausal women and female cancer survivors may be affected by the genitourinary syndrome of menopause (GSM), with a negative impact on sexual function and quality of life. A novel energy-based device among the treatment options for GSM is radiofrequency therapy (RFT). RFT is a treatment option that uses energy from radio waves to heat the tissue. The objective of this study was to assess the impact of RFT on sexual function in female cancer survivors (gynecologic and breast) and non-cancer menopausal women. Methods: In a single-arm prospective trial, the efficacy of RFT in both female cancer survivors (gynecologic and breast) and non-cancer menopausal women with sexual dysfunction at a tertiary and referral center (Imam Hossein Medical Center, Tehran, Iran) was evaluated between April 2022 and December 2022. The study protocol consisted of 3 monthly RFT sessions. Examination was performed at baseline (T0) and 3 months after the last RFT session (T1). The primary outcome was sexual function, which was assessed using the Female Sexual Function Index (FSFI). In addition, adverse events were evaluated during treatment and at T1. Results: A total of 37 female cancer survivors (mean [SD] age: 49.4 [8.9] years) and 37 non-cancer menopausal women (mean [SD] age: 53.8 [5.5] years) were enrolled. Patients exposed to RFT showed a significant improvement in FSFI scores when compared to baseline scores for both female cancer survivors (13.07, 95% CI: 12.27 - 13.86) and non-cancer menopausal women (13.18, 95% CI: 12.34 - 14.03). There was no difference in FSFI total score improvement between the two groups (t(72)=0.06, P=0.951). There were no serious adverse events associated with RFT. Conclusion: The efficacy of RFT as a treatment for sexual dysfunction has been demonstrated in both non-cancer menopausal women and female cancer survivors. In both groups, a significant improvement was confirmed.

Vaginal Laser Treatment for the Genitourinary Syndrome of Menopause in Breast Cancer Survivors: A Narrative Review

Vulvovaginal atrophy (VVA) is a chronic condition resulting from reduced estrogen levels during menopause. The North American Menopause Society and the International Society for the Study of Women's Sexual Health suggested the term "genitourinary syndrome of menopause" (GSM) to indicate the broader aspects of VVA. Breast cancer treatments, such as chemotherapy and endocrine therapy, can induce early and abrupt menopausal symptoms, including GSM, which negatively affects sexual function and the quality of life of the survivors. Vaginal laser therapy has emerged as a safe and effective option for the management of GSM in breast cancer survivors (BCSs). Two main types of lasers, the non-ablative erbium:YAG laser and fractional microablative CO2 vaginal laser, have been evaluated for GSM treatment. While there are few randomized controlled trials (RCTs) on the subject of BCSs, a wealth of prospective and retrospective studies have highlighted the beneficial effects of vaginal laser therapy on the symptoms of VVA, vaginal health, sexual function, and overall quality of life. More comprehensive research is essential to confirm its enduring effectiveness and safety, with a focus on conducting standardized and meticulously controlled investigations. This study is a narrative review that summarizes clinical trials ranging from the earliest to the most recent ones on laser treatment for GSM in BCSs.

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.
