A cohort study of topical vaginal estrogen therapy in women previously treated for breast cancer

Addressing Sexual Health in Breast Cancer Survivors: Evidence-Based Practices and Clinical Considerations

OPINION STATEMENT

Sexual health concerns are extremely prevalent among breast cancer survivors. The treatments used to treat and cure breast cancer - surgical removal of part or the whole breast, chemotherapy, radiation, and endocrine therapy - can have devastating impact on sexual function. Unfortunately, most patients are not given adequate preparation for these impending effects and can be blindsided by the resulting loss of sexual desire, vaginal dryness and decreased lubrication, pain with sex, vaginal stenosis, loss of nipple and breast sensation, muted or loss of orgasms and the resulting impact on sexuality and intimate relationships. Education about female sexual health is still lacking in most training programs and few cancer centers offer sexual health programs for cancer survivors. Oncology professionals and others who provide care for patients with breast cancer have the opportunity address sexual health, a vital aspect of quality of life. A focus on training and education, development of sexual health programs, and focus on sexual health in research is vital.

Genitourinary symptoms in women with breast cancer: frequency, severity and impact

PURPOSE

To improve understanding of genitourinary symptoms (GUS) in women with breast cancer (BC).

METHODS

Women with BC completed a survey assessing the type, severity, and impact of GUS experienced, and perceptions of treatment options.

RESULTS

Surveys were completed by 506 women: median age 60 years (range 30 - 83). The majority reported: being sexually active (52%); currently taking endocrine therapy (58%); and having early-stage BC (84%). 69% had GUS, with some changing (5%) or stopping (4%) endocrine therapy as a result. Vaginal dryness was the most common symptom (62%), followed by pain during penetration (41%) and itch (33%). Only 44% recalled being warned by their cancer doctor that BC treatment can cause GUS, and 38% reported never being asked about GUS. Being uncomfortable talking to a male healthcare professional was a moderate or major barrier to accessing advice and treatment for GUS in 28% of respondents. A minority reported using vaginal: lubricants (40%); moisturisers (25%); or oestrogens (16%). Amongst those using vaginal oestrogens, 45% found they helped "quite a bit" or "very much". The most frequently reported moderate to major barrier to using vaginal oestrogens was product information warning against use in women with BC.

CONCLUSIONS

Although GUS are very common in women with BC, the majority of women in our study do not recall being warned or asked about these symptoms. Healthcare professionals should initiate conversations about GUS and treatment options with women with BC to help reduce the impact of these symptoms.

Vaginal estrogen use in breast cancer survivors: a systematic review and meta-analysis of recurrence and mortality risks

OBJECTIVE

To assess the risk of breast cancer recurrence, breast cancer-specific mortality, and overall mortality for breast cancer survivors receiving vaginal estrogen therapy for genitourinary syndrome of menopause.

DATA SOURCES

From the inception of each database to April 6th, 2024, a systematic literature search was conducted in Google Scholar, PubMed, EMBASE, CINAHL, NCBI, and Science Direct. A secondary search was conducted on September 26th, 2024 utilizing Google Scholar, PubMed, EMBASE, CINAHL, and Science Direct.

STUDY ELIGIBILITY CRITERIA

We identified studies that reported on breast cancer recurrence defined per individual review criteria and considered both local and distant recurrence.

STUDY APPRAISAL AND SYNTHESIS METHODS

Three reviewers evaluated studies with eligibility criteria in mind. Breast cancer recurrence was the primary outcome. The secondary outcomes included: breast cancer mortality and overall mortality. Pooled unadjusted odds ratios with 95% confidence intervals were calculated using a random-effects model. We assessed the 95% prediction intervals to calculate the likely range within which we can expect to observe future individual values, based on a current model or dataset. We calculated the fragility index to evaluate the robustness of the pooled estimates.

RESULTS

Of 5522 articles identified, 8 observational studies were included in this meta-analysis. The use of vaginal estrogen in patients with a history of breast cancer was not associated with an increased risk of breast cancer recurrence (6 articles, 24,060 patients, odds ratio, 0.48; 95% confidence interval, 0.23-0.98). There was no increase in the risk of breast cancer mortality (4 articles, 61,695 patients, odds ratio 0.60; 95% confidence interval 0.18-1.95). Lastly, there was no increase in overall mortality with use of vaginal estrogen in breast cancer survivors (5 articles 59,724, odds ratio 0.46; 95% confidence interval 0.42-0.49).

CONCLUSION

The use of vaginal estrogen in patients with a history of breast cancer does not appear to be associated with an increased risk of breast cancer recurrence, breast cancer-specific mortality, or overall mortality.

From diagnosis to survivorship addressing the sexuality of women during cancer

For women diagnosed with cancer, side effects affecting their sexuality are extremely common and can be distressing and life-changing; however, most women are left in the dark without any guidance from their oncology teams regarding possible side effects and treatment options. American Society of Clinical Oncology clinical guidelines provide guidance on the recommended assessments related to the domains of sexual function and their respective interventions. Despite the existence of these guidelines, the reality is that only a few women with cancer are asked about sexual concerns that result from cancer treatments. Common barriers to sexuality discussion reported by oncology providers include a lack of qualification and knowledge, not having a place to refer patients, and not knowing how to start the conversation. Social media remains a widely untapped resource regarding sexuality and cancer interventions, as people are increasingly turning to social media for health information and advice. This may be especially relevant for sexuality, as oncologists may not feel comfortable or well-trained to discuss the topic, and patients may be reluctant to bring up sexual concerns during their visits. Social media can play a critical role in studying sexual health and in sexuality interventions, particularly in adolescent and young adult patients with cancer. Here, we discuss the lack of inclusion regarding sexuality in oncology, the rates of sexual dysfunction in patients with cancer, treatment options for common sexual concerns, how to utilize the reach of various social media channels, and provide patient and provider resources.

Effect of Vaginal Laser and Topical Therapies on Vulvovaginal Atrophy Symptoms in Breast Cancer Patients: A Systematic Review and Meta-Analysis

Background: Vulvovaginal atrophy (VVA) significantly impacts the quality of life in breast cancer patients leading to symptoms like vaginal dryness, dyspareunia, and genital discomfort. Quality of life in this context is measured using validated scales like the Vaginal Health Index, Visual Analog Scale (VAS), and the Female Sexual Function Index (FSFI). Methods: We performed a systematic review and meta-analysis to identify effective treatment options for VVA, including topical estrogen, systemic hormone therapy, vaginal DHEA, ospemifene, and non-hormonal methods like intravaginal laser therapy, moisturizers, and lubricants. A systematic search of four databases (MEDLINE, Scopus, CENTRAL, Embase) identified studies on VVA treatment efficacy in breast cancer patients, yielding 13,039 records, with 32 eligible studies and 8 included in the meta-analysis. Results: Significant improvements were found with intravaginal laser therapy, showing notable differences in the Vaginal Health Index (MD = 8.24, p < 0.01), dyspareunia (MD = -4.82, p = 0.05), and dryness (MD = -5.05, p = 0.01). However, no significant changes were observed in FSFI and vaginal pH. Notably only intravaginal laser therapy was included in the meta-analysis, as other treatment options lacked comparable data. Both hormonal and non-hormonal treatments improved quality of life, with laser therapy showing the most substantial effects. Conclusions: Intravaginal laser therapy is an effective treatment for VVA symptoms in breast cancer survivors, particularly in improving the Vaginal Health Index and reducing dyspareunia. Despite the strengths of the study, variability among studies, lack of RCT-s and data limitations, especially on long-term effects, present challenges.

Managing sexual health challenges in breast cancer survivors: A comprehensive review

The significant advancements in breast cancer management have led to an increase in the prevalence of breast cancer survivors. Despite their efficacy, these treatments can cause a variable range of side effects, significantly deteriorating the patients' quality of life. Sexual dysfunction, and in particular the genitourinary syndrome of menopause, represent one of the major causes of quality-of-life impairment among breast cancer patients, potentially affecting treatment adherence and compliance. If in the general population, hypoestrogenism-related symptoms are typically managed through systemic or topical estrogen administration, this approach is contraindicated in breast cancer patients for the potential increased risk of disease recurrence, urging the investigation of alternative measures. The aim of this review is to summarize the most up-to-date pharmacological and non-pharmacological interventions, as well as supportive measures, available for the management of sexual dysfunctions in breast cancer patients and survivors.

Measuring serum oestrogen levels in breast cancer survivors using vaginal oestrogens: a systematic review

PURPOSE

Vaginal oestrogens can be used to treat genitourinary symptoms in women with early breast cancer. Studies evaluating vaginal oestrogens have commonly measured serum oestrogen levels as a surrogate marker of safety, but methods vary. We sought to summarise the data on serum oestrogen measurement in women with breast cancer using vaginal oestrogens to better understand the methods, levels and reliability.

METHODS

We searched Medline, Embase, CENTRAL, SCOPUS and CINAHL from inception to October 2023 for clinical studies where serum oestrogen was measured in women with a history of early breast cancer using vaginal oestrogens. Studies with a reported testing methodology were included.

RESULTS

Nine studies met the inclusion criteria for this systematic review. Methods used to measure oestradiol and oestriol in selected studies included mass spectrometry and immunoassays; several studies used more than one with variable concordance. Mass spectrometry detected oestradiol levels down to a lower limit between 1.0 pg/mL and 3.0 pg/mL. Immunoassays such as ELISA (enzyme-linked immunosorbent assay), ECLIA (enhanced chemiluminiscence immunoassay) and RIA (radioimmunoassay) had lower detection limits ranging between 0.8 pg/mL and 10 pg/mL. Studies were heterogeneous in testing techniques used, timing of testing, and the population including with subsequent varying results in the effect on oestrogens reported.

CONCLUSIONS

Adopting consistent and standardised methods of measuring oestrogens in clinical trials involving women with early breast cancer on vaginal oestrogens is critical. Serum oestrogens are used as a surrogate marker of safety in this population, and good-quality data are necessary to enable clinicians and patients to feel confident in prescribing and taking vaginal oestrogens. Mass spectrometry, although more expensive, gives more reliable results when dealing with very low levels of oestrogens often found in women on aromatase inhibitors, compared to immunoassays.

Oncology: What You May Have Missed in 2023

Advances in oncology treatment methods have improved outcomes and quality of life for patients with cancer. However, care of these patients can be complex, and the contribution of physicians from different specialties is crucial. This article highlights important publications from 2023 on topics across a wide spectrum relating to the management of oncology patients. The literature was screened for significant new evidence that is relevant to internal medicine specialists and subspecialists whose focus is not oncology. Two articles address the importance of social interventions targeting end-of-life care for low-income and minority patients and the well-being of caregivers. Two additional articles address screening considerations in patients at risk for colorectal and lung cancer. Two more articles address safe use of hormone-related therapies to treat symptoms of menopause and prevent disease recurrence or progression in patients diagnosed with noninvasive breast neoplasia. Finally, several articles were included on topics related to COVID-19 vaccination in patients with cancer, use of cannabinoids for cancer pain control, chronic autoimmune adverse effects related to use of immune checkpoint inhibitors, and the incidence of second primary neoplasms.

Vaginal Estrogen Therapy Use and Survival in Females With Breast Cancer

Importance

Genitourinary syndrome of menopause can be treated with vaginal estrogen therapy. However, there are concerns about the safety of vaginal estrogen therapy in patients with breast cancer.

Objective

To determine whether the risk of breast cancer-specific mortality was higher in females with breast cancer who used vaginal estrogen therapy vs females with breast cancer who did not use hormone replacement therapy (HRT).

Design, Setting, and Participants

This cohort study analyzed 2 large cohorts, one each in Scotland and Wales, of females aged 40 to 79 years with newly diagnosed breast cancer. These population-based cohorts were identified from national cancer registry records from 2010 to 2017 in Scotland and from 2000 to 2016 in Wales and were followed up for breast cancer-specific mortality until 2020. Females were excluded if they had a previous cancer diagnosis (except nonmelanoma skin cancer). Data analysis was performed between August 2022 and August 2023.

Exposure

Use of vaginal estrogen therapy, including vaginal tablets and creams, was ascertained from pharmacy dispensing records of the Prescribing Information System for the Scotland cohort and from general practice prescription records for the Wales cohort.

Main Outcomes and Measures

The primary outcome was time to breast cancer-specific mortality, which was obtained from national mortality records. Time-dependent Cox proportional hazards regression models were used to calculate hazard ratios (HRs) and 95% CIs for breast cancer-specific mortality, comparing vaginal estrogen therapy users with HRT nonusers and adjusting for confounders, including cancer stage and grade.

Results

The 2 cohorts comprised 49 237 females with breast cancer (between 40 and 79 years of age) and 5795 breast cancer-specific deaths. Five percent of patients with breast cancer used vaginal estrogen therapy after breast cancer diagnosis. In vaginal estrogen therapy users compared with HRT nonusers, there was no evidence of a higher risk of breast cancer-specific mortality in the pooled fully adjusted model (HR, 0.77; 95% CI, 0.63-0.94).

Conclusions and Relevance

Results of this study showed no evidence of increased early breast cancer-specific mortality in patients who used vaginal estrogen therapy compared with patients who did not use HRT. This finding may provide some reassurance to prescribing clinicians and support the guidelines suggesting that vaginal estrogen therapy can be considered in patients with breast cancer and genitourinary symptoms.

A Recent Review of the Management of Postmenopausal Symptoms in Breast Cancer Survivors

The treatment strategy for postmenopausal symptoms resulting from estrogen deficiency in breast cancer survivors receiving endocrine therapy should differ from that in normal women. Several nonhormonal pharmacological therapies can be used to treat vasomotor symptoms. Cognitive-behavioral therapy can help alleviate psychophysiological symptoms, including depression and sleep disorders. Topical vaginal estrogen and moisturizers may aid in treating genitourinary symptoms. Additionally, chronic conditions must be individually managed. Prevention of osteoporosis should always be included in the management, and physicians should be alert to possible cardiovascular risk and cognitive function changes.

A systematic review of randomised clinical trials - The safety of vaginal hormones and selective estrogen receptor modulators for the treatment of genitourinary menopausal symptoms in breast cancer survivors

Therapies utilised in breast cancer management have been found to induce or worsen the genitourinary symptoms of menopause (GSM), a group of physical symptoms associated with the systemic loss of estrogen. These symptoms are often undertreated due to concerns surrounding cancer recurrence, especially when considering treatments with possible pro-estrogenic effects. As breast cancer prognosis continues to improve, clinicians are increasingly focussing on managing these symptoms amongst survivors. This systematic review primarily aimed to determine the risk of breast cancer recurrence amongst survivors using vaginal hormones and selective estrogen receptor modulator therapies recommended for use in GSM in the United Kingdom amongst currently published randomised clinical trials (RCTs). The secondary aim was to determine whether these RCTs demonstrated a significant rise in serum estrogen levels following the use of these therapies. A literature search revealed three RCTs suitable for assessment, two evaluating vaginal estrogen and one evaluating vaginal DHEA treatment. Our review determined that amongst published RCTs, no studies have aimed to assess for breast cancer recurrence; however among the studies observing for serious adverse effects of vaginal estrogen preparations, none have reported an increased incidence. Furthermore, these studies did not report a persistent or significant increase in serum estrogen levels following the use of vaginal estrogen products and low concentration (3.25 mg/day) DHEA gel. Larger RCTs studying commonly used vaginal preparations and selective estrogen receptor modulator treatments for GSM over longer follow-up periods will be vital to better assess the risk of breast cancer recurrence in survivors receiving these treatments.

Safety and Serum Estradiol Levels in Hormonal Treatments for Vulvovaginal Atrophy in Breast Cancer Survivors: A Systematic Review and Meta-Analysis

Vulvo-vaginal atrophy (VVA) or genitourinary syndrome of menopause (GSM) is a common condition among breast cancer (BC) patients, especially those undergoing antiestrogen therapy. Despite being an option in refractory cases, the safety of hormonal treatment remains uncertain in this population. The aim of this study was to review the safety and serum estrogen levels of hormonal therapy in patients with BC history presenting with VVA symptoms. Pubmed, Embase, and Cochrane were searched for studies comparing different hormonal treatment options for VVA in breast cancer survivors. Statistical analysis was performed using a random effects model and heterogeneity using Cochran's Q-statistic and the I2 index. We included 17 studies, of which 5 were randomized controlled trials (RCTs). Treatment modalities included in this study were topical vaginal estradiol and estriol preparations, vaginally applied testosterone, DHEA, and ospemifene. We found that, among patients treated with the estriol and estradiol preparations, there was an average increase of 7.67 pg/mL (SMD 7.67 pg/mL; 95% CI -1.00, 16.35; p < .001). Analysis of the testosterone group found temporary peaks of serum estradiol levels, but 1 study showed persistent elevation above normal postmenopausal levels. One study with prasterone revealed no elevation of serum estradiol concentration. One study with ospemifene demonstrated no increase in the risk of BC recurrence. In conclusion, among treatments available for BC survivors, low-dose vaginal estrogen showed the smallest changes in serum estradiol levels and had the most evidence, but safety remains unclear, especially for patients on aromatase inhibitors. Alternative treatments such as ospemifene need more data supporting safety and efficacy. These results suggest that concerns related to cancer recurrence should keep aiming for the lowest possible concentration.

Update on Breast Cancer

This article reviews recent advances in the treatment of breast cancer. The goal in selecting these recent articles was to help identify literature that may change the clinical practice of women's health for practitioners in the primary care setting. Articles were identified by reviewing the high-impact medical and women's health journals, national guidelines, ACP JournalWise, and NEJM Journal Watch. In this Clinical Update, we selected recent publications relevant to the treatment and complications of treatment of breast cancer.

Therapeutic Choices for Genitourinary Syndrome of Menopause (GSM) in Breast Cancer Survivors: A Systematic Review and Update

(1) Background: Genitourinary syndrome of menopause (GSM) is a medical condition that can affect breast cancer survivors (BCS). This is a complication that often can occur as a result of breast cancer treatment, causing symptoms such as vaginal dryness, itching, burning, dyspareunia, dysuria, pain, discomfort, and impairment of sexual function. BCS who experience these symptoms negatively impact multiple aspects of their quality of life to the point that some of them fail to complete adjuvant hormonal treatment; (2) Methods: In this systematic review of the literature, we have analyzed possible pharmacological and non-pharmacological treatments for GSM in BCS. We reviewed systemic hormone therapy, local hormone treatment with estrogens and androgens, the use of vaginal moisturizers and lubricants, ospemifene, and physical therapies such as radiofrequency, electroporation, and vaginal laser; (3) Results: The data available to date demonstrate that the aforementioned treatments are effective for the therapy of GSM and, in particular, vulvovaginal atrophy in BCS. Where possible, combination therapy often appears more useful than using a single line of treatment; (4) Conclusions: We analyzed the efficacy and safety data of each of these options for the treatment of GSM in BCS, emphasizing how often larger clinical trials with longer follow-ups are needed.

Estrogen therapy after breast cancer diagnosis and breast cancer mortality risk

PURPOSE

The safety of local estrogen therapy in patients on adjuvant endocrine treatment is questioned, but evidence on the issue is scarce. This nested case-control registry-based study aimed to investigate whether estrogen therapy affects breast cancer mortality risk in women on adjuvant endocrine treatment.

METHODS

In a cohort of 15,198 women diagnosed with early hormone receptor (HR)-positive breast cancer and adjuvant endocrine treatment, 1262 women died due to breast cancer and were identified as cases. Each case was matched with 10 controls. Exposure to estrogen therapy with concurrent use of aromatase inhibitors (AIs), tamoxifen, or both sequentially, was compared between cases and controls.

RESULTS

No statistically significant difference in breast cancer mortality risk was seen in patients with exposure to estrogen therapy concurrent to endocrine treatment, neither in short-term or in long-term estrogen therapy use.

CONCLUSIONS

The study strengthens current evidence on local estrogen therapy use in breast cancer survivors, showing no increased risk for breast cancer mortality in patients on adjuvant AIs or tamoxifen.

Using menopausal hormone therapy after a cancer diagnosis in Ireland

BACKGROUND

Menopause may cause a constellation of symptoms that affect quality of life. Many women will have menopause induced or exacerbated by treatment for cancer whether that be through surgery, chemotherapy, radiotherapy, or anti-endocrine therapy. As treatments advance, the number of people living with and beyond a cancer diagnosis is set to increase over the coming years meaning more people will be dealing with the after effects of cancer and its treatment.

AIMS

This review aims to summarise available data to guide clinicians treating women with menopausal symptoms after the common cancer diagnoses encountered in Ireland. The use of menopausal hormone therapy is discussed as well as non-hormonal and non-pharmacological options.

CONCLUSIONS

Managing menopausal symptoms is an important consideration for all physicians involved in the care of people living with and beyond a cancer diagnosis. High-quality data may not be available to guide treatment decisions, and, thus, it is essential to take into account the impact of the symptoms on quality of life as well as the likelihood of recurrence in each individual case.

Association of Vaginal Estradiol Tablet With Serum Estrogen Levels in Women Who Are Postmenopausal: Secondary Analysis of a Randomized Clinical Trial

IMPORTANCE

Half of women who are postmenopausal have genitourinary discomfort after menopause. Recommended therapies include low-dose vaginal estrogen. Individuals with a history of breast cancer or venous thromboembolism may have concerns about the safety of this intervention.

OBJECTIVE

To compare serum estrogen concentrations with the use of vaginal estrogen, 10 μg, tablet vs placebo in women who are postmenopausal.

DESIGN, SETTING, AND PARTICIPANTS

This is a secondary, post hoc analysis of data from a randomized clinical trial of treatment for moderate to severe genitourinary syndrome in women who are postmenopausal. The study was conducted at Kaiser Permanente Washington Health Research Institute and the University of Minnesota from April 11, 2016, to April 23, 2017. Measurements and data analysis were performed from November 3, 2020, to September 23, 2022.

INTERVENTIONS

Participants were randomly assigned to vaginal estradiol tablet (10 μg/d for 2 weeks and then twice weekly) plus placebo gel (3 times weekly) or dual placebo for 12 weeks.

MAIN OUTCOMES AND MEASURES

In this post hoc analysis, baseline and week 12 serum estradiol, estrone, and sex hormone-binding globulin (SHBG) concentrations were measured by a chemiluminescent assay. Week 12 values of the 3 analytes were compared by baseline participant characteristics. Linear models compared week 12 estradiol concentrations between treatment groups, adjusted for baseline characteristics.

RESULTS

A total of 174 women, mean (SD) age 61 (4) years, were included. Those in the estrogen group (n = 88) were more likely to have higher geometric mean (SD) week 12 serum estradiol concentrations (4.3 [2.2 pg/mL]) than those in the placebo group (n = 86) (3.5 [2.1] pg/mL) (P = .01). Adjusted for pretreatment hormone concentrations, age, clinical site, and body mass index, assignment to the estrogen vs placebo treatment group was significantly associated with higher week 12 estradiol concentrations (23.8% difference; 95% CI, 6.9%-43.3%). Most (121 of 174 [69.5%]) participants had enrollment serum estradiol concentrations higher than 2.7 pg/mL. Of women starting treatment at estradiol levels lower than or equal to 2.7 pg/mL, 38.1% (8 of 21) in the estrogen group and 34.4% (11 of 32) in the placebo group had estradiol concentrations higher than 2.7 pg/mL after 12 weeks of study participation (P = .78). Treatment assignment was not associated with week 12 estrone or SHBG concentrations.

CONCLUSIONS AND RELEVANCE

In this secondary analysis of a randomized clinical trial, a significant, although small, increase in serum estradiol levels was noted after 12 weeks of vaginal estrogen administration. The clinical relevance of this small increase is uncertain.

Systemic or Vaginal Hormone Therapy After Early Breast Cancer: A Danish Observational Cohort Study

BACKGROUND

Women treated for breast cancer (BC) often suffer genitourinary syndrome of menopause. These symptoms may be alleviated by vaginal estrogen therapy (VET) or menopausal hormone therapy (MHT). However, there are concerns of risks of recurrence of BC and death following treatment.

METHODS

Our study included longitudinal data from a national cohort of postmenopausal women, diagnosed 1997-2004 with early-stage invasive estrogen receptor-positive nonmetastatic BC, who received no treatment or 5 years of adjuvant endocrine therapy. We ascertained prescription data on hormone therapy, VET or MHT, from a national prescription registry. We evaluated mortality and risk of recurrence associated with use of VET and MHT vs non-use using multivariable models adjusted for potential confounders.

RESULTS

Among 8461 women who had not received VET or MHT before BC diagnosis, 1957 and 133 used VET and MHT, respectively, after diagnosis. Median follow-up was 9.8 years for recurrence and 15.2 years for mortality. The adjusted relative risk of recurrence was 1.08 (95% confidence interval [CI] = 0.89 to 1.32) for VET (1.39 [95% CI = 1.04 to 1.85 in the subgroup receiving adjuvant aromatase inhibitors]) and 1.05 (95% CI = 0.62 to 1.78) for MHT. The adjusted hazard ratios for overall mortality were 0.78 (95% CI = 0.71 to 0.87) and 0.94 (95% CI = 0.70 to 1.26) for VET and MHT, respectively.

CONCLUSIONS

In postmenopausal women treated for early-stage estrogen receptor-positive BC, neither VET nor MHT was associated with increased risk of recurrence or mortality. A subgroup analysis revealed an increased risk of recurrence, but not mortality, in patients receiving VET with adjuvant aromatase inhibitors.

The British menopause society consensus statement on the management of oestrogen deficiency symptoms, arthralgia and menopause diagnosis in women with treated for early breast cancer

This guidance document by the British Menopause Society provides an overview of the management of women experiencing oestrogen deficiency symptoms and arthralgia following a breast cancer diagnosis. It is now recommended breast cancer patients are referred to health care professionals with an expertise in menopause for management of such symptoms, which in turn often involves liaison with patients' breast cancer teams.¹ However, as many women initially present to primary health care professionals for advice, this statement is aimed to support the latter in such consultations by providing information about symptom aetiology, current management strategies and controversies and identifying useful practice points. This is an updated version of the 2018 consensus statement prepared by Miss Jo Marsden Consultant Breast Surgeon, King's College Hospital, London, (retired), Mr Mike Marsh, Consultant Gynae-endocrinologist, King's College Hospital, London, Dr Anne Rigg, Consultant Medical Oncologist, Guy's and St Thomas' Hospital, London.

Management of Breast Cancer Survivors by Gynecologists

Breast cancer patients commonly present to their OBGYN during the process of diagnosis and treatment of breast cancer both for specific gynecologic needs and for primary care follow up. These patients require counseling on contraception, hormone use, and fertility at diagnosis. During treatment and survivorship, patients will face a variety of side effects from treatments leading to vasomotor symptoms, vulvovaginal discomfort, sexual dysfunction, osteoporosis, and vaginal bleeding. This chapters aims to enlighten providers on the unique range of issues a gynecologist may face when caring for breast cancer patients.

Cost-Effectiveness of perioperative Vaginally Administered estrogen in postmenopausal women undergoing prolapse surgery (EVA trial): study protocol for a multicenter double-blind randomized placebo-controlled trial

BACKGROUND

Surgery for pelvic organ prolapse (POP) is associated with high recurrence rates. The costs associated with the treatment of recurrent POP are huge, and the burden from women who encounter recurrent POP, negatively impacts their quality of life. Estrogen therapy might improve surgical outcome for POP due to its potential beneficial effects. It is thought that vaginal estrogen therapy improves healing and long-term maintenance of connective tissue integrity. Hence, this study aims to evaluate the cost-effectiveness of perioperative vaginal estrogen therapy in postmenopausal women undergoing POP surgery.

METHODS

The EVA trial is a multi-center double-blind randomized placebo-controlled trial conducted in the Netherlands comparing the effectiveness and costs-effectiveness of vaginal estrogen therapy. This will be studied in 300 postmenopausal women undergoing primary POP surgery, with a POP-Q stage of ≥ 2. After randomization, participants administer vaginal estrogen cream or placebo cream from 4 to 6 weeks preoperative until 12 months postoperative. The primary outcome is subjective improvement of POP symptoms at 1 year follow-up, measured with the Patient Global Impression of Improvement (PGI-I) scale. Secondary outcomes are POP-Q anatomy in all compartments, re-interventions, surgery related complications, general and disease specific quality of life, sexual function, signs and complaints of vaginal atrophy, vaginal pH, adverse events, costs, and adherence to treatment. Follow up is scheduled at 6 weeks, 6 months and 12 months postoperative. Data will be collected using validated questionnaires and out-patient visits including gynecological examination performed by an independent gynecologist.

DISCUSSION

This study investigates whether perioperative vaginal estrogen will be cost-effective in the surgical treatment of POP in postmenopausal women. It is hypothesized that estrogen therapy will show a reduction in recurrent POP symptoms and a reduction in reoperations for POP, with subsequent improved quality of life among women and cost savings.

Treatment of Urogenital Symptoms in Individuals With a History of Estrogen-dependent Breast Cancer: Clinical Consensus

SUMMARY

With an estimated 3.8 million breast cancer survivors in the United States, obstetrician-gynecologists often are on the front lines of addressing survivorship issues, including the hypoestrogenic-related adverse effects of cancer therapies or early menopause in survivors (1). Although systemic and vaginal estrogen are used widely for symptomatic relief of genitourinary syndrome of menopause in the general population, among individuals with a history of hormone-sensitive cancer, there is uncertainty about the safety of hormone-based therapy, leading many individuals with bothersome symptoms to remain untreated, with potential negative consequences on quality of life (2). An effective management strategy requires familiarity with a range of both hormonal and nonhormonal treatment options, knowledge about the pharmaceutical mechanisms of action, and the ability to tailor treatment based on individual risk factors. This clinical consensus document was developed using an a priori protocol in conjunction with two authors specializing in urogynecology and gynecologic oncology. This document has been updated to review the safety and efficacy of newer hormonal treatment options as well as nonhormonal modalities.

[Genitourinary menopause syndrome. Postmenopausal women management: CNGOF and GEMVi clinical practice guidelines]

INTRODUCTION

Genitourinary menopause syndrome (SGUM) is defined as a set of symptoms associated with a decrease of estrogen and other sexual steroids during menopause. The main symptoms are vulvovaginal (dryness, burning, itching), sexual (dyspareunia), and urinary (urinary infections, pollakiuria, nycturia, pain, urinary incontinence by urgenturia). SGUM leads to an alteration of the quality of life, and affects especially women's sexuality.

OBJECTIVE

The objective of this review was to elaborate guidelines for clinical practice regarding the management of SGUM in postmenopausal women, and in particular, in women with a history of breast cancer, treated or not with hormone therapy.

MATERIALS AND METHODS

A systematic review of the literature on SGUM management was conducted on Pubmed, Medline and Cochrane Library. Recommendations from international scholarly societies were also taken into account: International Menopause Society (IMS) https://www.imsociety.org, The North American Menopause Society (NAMS) https://www.menopause.org, Canadian Menopause Society https://www.sigmamenopause.com, European Menopause and Andropause Society (EMAS) https://www.emas-online.org, International Society for the Study of Women's Sexual Health (ISSWSH) https://www.isswsh.org.

RESULTS

Vaginal use of lubricants, moisturizers and hyaluronic acid improves the symptoms of SGUM and may be offered to all patients. For postmenopausal women, local estrogen will be preferred to the oral route because of their safety and efficacy on all symptoms of SGUM during low-dose use. Prasterone is a local treatment that can be proposed as an effective alternative for the management of dyspareunia and sexual function disorder. Current data on oral testosterone, tibolone, oral or transdermal DHEA and herbal medicine are currently limited. Ospemifène, which has shown a significant improvement in sexual symptoms, is not currently marketed in France. In the particular case of women with a history of breast cancer, non-hormonal regimens are a first-line therapy. Current data on the risk of breast cancer recurrence when administering low-dose local estrogen are reassuring but do not support a conclusion that this treatment is safe.

CONCLUSION

SGUM is a common symptom that can affect the quality of life of postmenopausal women. A treatment should be systematically proposed. Local non-hormonal treatment may be offered in all women. Local low-dose estrogen therapy and Prasterone has shown an interest in the management of symptoms. In women before a history of breast cancer, local non-hormonal treatment should be offered first-line. The safety of low-dose local estrogen therapy and Prasterone cannot be established at this time. Other alternatives exist but are not currently recommended in France due to lack of data.

Efficacy and safety of ultra-low dose 0.005% estriol vaginal gel for the treatment of vulvovaginal atrophy in postmenopausal women with early breast cancer treated with nonsteroidal aromatase inhibitors: a phase II, randomized, double-blind, placebo-controlled trial

Supplemental Digital Content is available in the text

Objective:

To assess the efficacy and safety of ultra-low dose 0.005% estriol vaginal gel in women with breast cancer receiving nonsteroidal aromatase inhibitors (NSAIs) and experiencing treatment-related vulvovaginal symptoms and signs.

Methods:

Women with hormone receptor-positive early breast cancer receiving NSAIs were randomized to either estriol vaginal gel or placebo for 12 weeks. Vaginal maturation, vaginal pH, and total and individual scores of symptoms and signs of vulvovaginal atrophy were assessed at baseline and at weeks 3 and 12; sexual functioning was also evaluated using the Female Sexual Functioning Index (FSFI) questionnaire, as well as circulating estrogens, follicle-stimulating hormone (FSH) and luteinizing hormone (LH).

Results:

Sixty-one women with a mean age of 59 years were included: 50 received 0.005% estriol vaginal gel and 11 received placebo. Active treatment significantly improved maturation value and pH, vaginal dryness and global scores of symptoms and signs. Active treatment also increased the total FSFI score and all the FSFI domains, with the exception of pain. Small oscillations were observed in FSH and LH, which remained within the postmenopausal range. Estriol levels increased initially and normalized by week 12, and estradiol and estrone remained mostly undetectable throughout the study.

Conclusions:

Ultra-low dose 0.005% estriol vaginal gel showed efficacy in improving the symptoms and signs of vulvovaginal atrophy. These results, together with minimal oscillations in hormonal levels throughout the treatment, support the use of ultra-low dose 0.005% estriol vaginal gel as a treatment option for vulvovaginal atrophy in women with breast cancer receiving NSAIs with an indication for treatment with vaginal estrogens.

Hormonal management of menopausal symptoms in women with a history of gynecologic malignancy

OBJECTIVE

The aim of the study was to review the role of hormone therapy in menopausal patients with breast cancer and gynecologic malignancies.

METHODS

We searched MEDLINE (via PubMed) using a combination of keywords and database-specific subject headings for the following concepts: menopause, hormone therapy, and cancer. Editorials, letters, case reports, and comments were excluded, as were non-English articles. Additional references were identified by hand-searching bibliographies of included articles. The searches yielded a total of 1,484 citations. All citations were imported into EndNote X9, where they were screened by the authors.

RESULTS

In breast cancer survivors, systemic hormone therapy is not recommended, whereas local low-dose estrogen therapy may be considered after discussion with the patient's oncologist. Among endometrial cancer survivors, hormone therapy is considered safe in low-risk cancers but should be avoided in high-risk subtypes. For survivors of epithelial ovarian cancer and cervical cancer, hormone therapy can be considered, but should be avoided in women with estrogen-sensitive histologic subtypes.

CONCLUSIONS

The risks of hormone therapy should be assessed on an individual basis, with consideration of age, type of hormone therapy, dose, duration of use, regimen, route, and prior exposure. Systemic hormone therapy is not recommended in breast cancer survivors, whereas vaginal low-dose estrogen appears safe. Hormone therapy may be used by endometrial, cervical, and ovarian cancer survivors with low-risk, non-estrogen-receptor-positive subtypes. Video Summary: http://links.lww.com/MENO/A516.

Genitourinary Syndrome of Menopause: Current Treatment Options in Breast Cancer Survivors - Systematic Review

Breast cancer survivors (BCS) usually receive treatments which lead to persistent oestrogen suppression, which may cause atrophic vaginitis in a large proportion of these women. The most effective treatments for vulvovaginal atrophy (VVA) are based on local oestrogen therapy. However, these treatments are restricted in BCS due to the controversy over their use in women who had hormone-dependent tumours. Therefore, it is common to find untreated symptoms that affect sexual function and quality of life in BCS, thereby leading to the discontinuation of anti-oestrogenic treatments. This systematic review aims to discuss the current treatment options available for the genitourinary syndrome of menopause (GSM) in BCS. A comprehensive literature search was conducted electronically using Embase and PubMed to retrieve studies assessing treatment options for GSM or VVA in BCS up to April 2020. Studies evaluating treatments in different BCS cohorts were excluded. A total of 29 studies were finally included in the review. Non-hormonal treatments are the first-line treatment for VVA, but when these are not effective for symptom relief, other options can be considered, such as local oestrogen, erbium laser or CO2 laser and local androgens. The present data suggest that these therapies are effective for VVA in BCS; however, safety remains controversial and a major concern with all of these treatments.

Usefulness of patient-reported outcomes to assess the effectiveness of topical hormonal therapy for gynecologic symptoms after antihormonal treatment for breast cancer

The aim of this retrospective study was to assess the efficacy of topical hormonal therapy (THT) to relieve vaginal symptoms resulting from antihormonal therapy in women with hormone receptor-positive breast cancer. A total of 74 breast cancer patients who received THT for vaginal complaints were retrospectively identified and statistically matched with 74 control breast cancer patients with vaginal complaints with no documented use of THT. Symptom scores were recorded from the center's proprietary patient-reported outcomes database, Patient Care Monitor (ConcertoHealthAI, Boston). A baseline score was noted at the initiation of antihormonal therapy and was followed at 6 and 12 months. The median differences between baseline, 6-month, and 12-month scores were analyzed. Repeated measures analysis of variance assessed the impact of topical hormonal replacement. There was no statistically significant difference in score change between the two groups at 6 and 12 months. In the active THT group, there were no statistically significant differences in vaginal complaints or sexual problems over time: {F (2, 146) = 0.99, P = 0.369; and F (2, 146) = 1.56, P = 0.217}, respectively. In this study, the use of topical hormonal replacement was not effective in alleviating vaginal symptoms.

Topical estrogen prescribing patterns for urogenital atrophy among women with breast cancer: results of a national provider survey

OBJECTIVE

The aim of the study was to evaluate knowledge, attitudes, and practice patterns of physicians prescribing topical estrogen for women with urogenital atrophy and a history of breast cancer.

METHODS

A cross-sectional survey of breast surgeons, urogynecologists, and gynecologists was distributed via their professional societies: the American Society of Breast Surgeons (ASBrS), the American Urogynecologic Society (AUGS), and the Society of Gynecologic Surgeons (SGS). Providers reported level of comfort prescribing vaginal estrogen for urogenital symptoms for women with different categories of breast cancer and current treatment: estrogen receptor (ER) negative, ER positive no longer on endocrine therapy, and ER positive currently on adjuvant endocrine therapy. General knowledge questions assessed agreement on a 5-point Likert scale to statements about vaginal estrogen safety and pharmacology.

RESULTS

A total of 820 physicians completed the survey: 437 responses from the ASBrS (response rate, 26.7%), 196 from AUGS (15%), and 187 from SGS (44.5%). The majority of physicians (84%), regardless of specialty, felt comfortable prescribing vaginal estrogen to women with a history of ER-negative cancer: 65.7% felt comfortable prescribing for women with ER-positive breast cancer no longer on endocrine therapy; 51.3% for women on an aromatase inhibitor; and 31.4% for women on tamoxifen. Urogynecologists were significantly more comfortable than breast surgeons prescribing vaginal estrogen for the lowest risk patients, whereas breast surgeons had the highest level of comfort for women currently on endocrine therapy.

CONCLUSIONS

This study highlights heterogeneity in practice patterns both within and across specialties. The clinical variation seen in this study suggests providers may benefit from increased knowledge regarding vaginal estrogen.

British Menopause Society consensus statement on the management of estrogen deficiency symptoms, arthralgia and menopause diagnosis in women treated for early breast cancer

This guidance document by the British Menopause Society provides an overview of the management of women experiencing estrogen deficiency symptoms and arthralgia following a breast cancer diagnosis. It is now recommended that breast cancer patients are referred to health care professionals with an expertise in menopause for the management of such symptoms, which in turn often involves liaison with patients' breast cancer teams. However, as many women initially present to primary health care professionals for advice, this statement is aimed to support the latter in such consultations by providing information about symptom aetiology, current management strategies and controversies and identifying useful practice points.

WISDOM survey: attitudes and behaviors of physicians toward vulvar and vaginal atrophy (VVA) treatment in women including those with breast cancer history

OBJECTIVE

To evaluate and compare physicians' behaviors and attitudes regarding vulvar and vaginal atrophy (VVA) treatment in menopausal women, including women with breast cancer, using an internet-based survey.

METHODS

The WISDOM survey queried obstetricians and gynecologists (OB/GYNs) and primary care physicians (PCPs) with 23 multipart questions assessing behaviors and attitudes towards VVA treatment.

RESULTS

Of 2,424 surveys sent, 945 (39%) responded and 644 (27%) were completed. Of the menopausal women seen by OB/GYNs and PCPs, 44% to 55% reported having VVA symptoms. Physicians prescribed VVA treatments primarily because of effectiveness. Only 34% of OB/GYNs and 17% of PCPs felt comfortable prescribing VVA therapies to women with a personal history of breast cancer. In general, the most common VVA treatment recommended by all was prescription therapy (49%; with or without other therapies) in the form of US Food and Drug Administration-approved vaginal estrogen creams. More OB/GYNs (72%) than PCPs (47%) disagreed that VVA was best treated with over the counter than prescription products. Out-of-pocket cost and fear of risks associated with estrogens were believed to be the main barriers for why women choose not to get treated and why they discontinue treatment.

CONCLUSIONS

More OB/GYNs than PCPs prescribed VVA treatment, especially vaginal estrogens, for menopausal women, but both groups generally had similar attitudes and behaviors regarding VVA treatment. Physician comfort was low when prescribing to women with a history of breast cancer, despite women's health medical societies supporting vaginal estrogen use in women with a history of estrogen-dependent breast cancer who were unresponsive to nonhormonal therapies when offered in consultation with their oncologist.

Topical Estrogen Prescription Fill Rates for Women With a History of Breast Cancer Who Are Taking Hormone Therapy

OBJECTIVE

To evaluate how often women with a history of breast cancer who are taking hormone therapy (HT) filled prescriptions for topical estrogens and whether this frequency varied over time and by type of HT used.

METHODS

We performed a retrospective cohort study using medical and outpatient drug claims from a large commercial claims database for the years 2010-2015. Women younger than age 65 years taking HT for breast cancer were classified as users of 1) tamoxifen only, 2) aromatase inhibitor(s) only, or 3) any other or multiple HTs. Our outcome variable was filling a prescription for topical estrogen in a given year. We used multivariable logistic regression models estimated with generalized estimating equations to determine whether the fill rate varied over time and by HT category adjusting for age, receipt of surgical or radiation treatment, types of outpatient health care provider visits, and comorbidities.

RESULTS

We identified 352,118 records from 176,012 unique patients (mean age 54.3 years, range 18-64 years) who met eligibility criteria. Aromatase inhibitors were used more commonly (56.0% of patient-years) than tamoxifen (38.8%). Overall, 3.0% (range 2.9-3.1%) of women filled any topical estrogen prescription in a given calendar year. More than half of filled topical estrogen prescriptions were for tablets (57.0%) with the remainder for creams (25.8%) and rings (17.3%). In adjusted analyses, the fill rate for women taking tamoxifen was significantly less (2.4%; 95% CI 2.3-2.5%) than for women taking aromatase inhibitors (3.3%; 95% CI 3.2-3.4%). There was a small but statistically significant increase in fill rates across years (odds ratio 1.03, 95% CI 1.02-1.04).

CONCLUSION

A small proportion of women with a history of breast cancer who were taking HT filled a topical estrogen prescription, with significant differences by type of HT. More evidence is needed to inform national guidelines regarding safety and appropriate use of topical estrogens in this patient population.

Vaginal estrogen and mammogram results: case series and review of literature on treatment of genitourinary syndrome of menopause (GSM) in breast cancer survivors

OBJECTIVE

To examine mammographic density before and after at least 1 year of vaginal estrogen use in a small cohort of healthy postmenopausal women and women with a personal history of breast cancer.

METHODS

We extracted data via chart review of patients from a single practitioner's menopause specialty clinic in Baltimore, MD. Mammographic change was primarily determined via the Bi-RADS scoring system, including the Bi-RADS density score. In addition, we conduct a narrative review of the current literature on the usage of local estrogen therapy, and systemic and local alternatives in the treatment of genitourinary syndrome of menopause (GSM) in breast cancer survivors.

RESULTS

Twenty healthy postmenopausal women and three breast cancer survivors fit our inclusion criteria. Amongst these two groups, we did not find an increase in mammographic density after at least 1 year and up to 18 years of local vaginal estrogen. Ospemifene use in one patient did not appear to be associated with any change in Bi-RADS score. Our narrative review found little data on the effects of vaginal estrogen therapy or newer alternative systemic therapies such as ospemifene on mammographic density.

CONCLUSIONS

Low-dose vaginal estrogen use for 1 or more years in a small cohort of women with GSM did not appear to be associated with any changes in breast density or Bi-RADS breast cancer risk scores in the majority of study participants, including three breast cancer survivors. Larger long-term controlled clinical trials should be conducted to examine the effects of low-dose vaginal estrogen on mammographic density in women with and without a personal history of breast cancer. Furthermore, relative efficacy and risk of vaginal estrogen compared with other forms of treatment for GSM should also be studied in long-term trials.

Managing Menopausal Symptoms and Associated Clinical Issues in Breast Cancer Survivors

OBJECTIVE

Review evidence to guide management of menopausal signs and symptoms in women after breast cancer and make recommendations accordingly.

EVIDENCE

Randomized controlled clinical trials, observational studies, evidence-based guidelines, and expert opinion from professional societies.

BACKGROUND

Symptoms and clinical problems associated with estrogen depletion-sleep disorders, vulvovaginal atrophy (VVA), vasomotor symptoms (VMS), mood changes, depressive symptoms, cardiovascular disease, osteopenia, and osteoporosis-confront the estimated 9.3 million breast cancer survivors globally.

RECOMMENDATIONS

Following breast cancer, women should not generally be treated with menopausal hormone therapy or tibolone but should optimize lifestyle. Women with moderate to severe symptoms may benefit from mind-brain behavior or nonhormone, pharmacologic therapy. The selective serotonin/noradrenaline reuptake inhibitors and gabapentenoid agents improve VMS and quality of life. For osteoporosis, nonhormonal agents are available. Treatment of VVA remains an area of unmet need. Low-dose vaginal estrogen is absorbed in small amounts with blood levels remaining within the normal postmenopausal range but could potentially stimulate occult breast cancer cells, and although poorly studied, is not generally advised, particularly for those on aromatase inhibitors. Intravaginal dehydroepiandrosterone and oral ospemiphene have been approved to treat dyspareunia, but safety after breast cancer has not been established. Vaginal laser therapy is being used for VVA but efficacy from sham-controlled studies is lacking. Therapies undergoing development include lasofoxifene, neurokinin B inhibitors, stellate ganglion blockade, vaginal testosterone, and estetrol.

CONCLUSIONS

Nonhormone options and therapies are available for treatment of estrogen depletion symptoms and clinical problems after a diagnosis of breast cancer. Individualization of treatment is essential.

Evaluating the efficacy of vaginal dehydroepiandosterone for vaginal symptoms in postmenopausal cancer survivors: NCCTG N10C1 (Alliance)

BACKGROUND

Women with estrogen deficiencies can suffer from vaginal symptoms that negatively impact sexual health. This study evaluated vaginal dehydroepiandrosterone (DHEA) for alleviation of vaginal symptoms.

METHODS

This three-arm randomized, controlled trial evaluated DHEA 3.25 mg and DHEA 6.5 mg, each compared to a plain moisturizer (PM) over 12 weeks, to improve the severity of vaginal dryness or dyspareunia, measured with an ordinal scale, and overall sexual health using the Female Sexual Function Index (FSFI). Postmenopausal women with a history of breast or gynecologic cancer who had completed primary treatment, had no evidence of disease, and reported at least moderate vaginal symptoms were eligible. The mean change from baseline to week 12 in the severity of vaginal dryness or dyspareunia for each DHEA dose was compared to PM and analyzed by two independent t tests using a Bonferroni correction.

RESULTS

Four hundred sixty-four women were randomized. All arms reported improvement in either dryness or dyspareunia. Neither DHEA dose was statistically significantly different from PM at 12 weeks (6.25 mg, p = .08; 3.25 mg, p = 0.48), although a significant difference at 8 weeks for 6.5 mg DHEA was observed (p = 0.005). Women on the 6.5 mg arm of DHEA reported significantly better sexual health on the FSFI (p < 0.001). There were no significant differences in provider-graded toxicities and few significant differences in self-reported side effects.

CONCLUSION

PM and DHEA improved vaginal symptoms at 12 weeks. However, vaginal DHEA, 6.5 mg, significantly improved sexual health. Vaginal DHEA warrants further investigation in women with a history of cancer.

Safety issues associated with using medication to treat overactive bladder

INTRODUCTION

The mainstay of overactive bladder treatment is the use of anticholinergic medication with its common side effects well known. This review focused on three less well-known safety issues when treating OAB. Areas covered: Patients with increased anticholinergic load are at risk of cognitive decline, dementia or even death. The elderly are particularly at risk due to polypharmacy. Botulinum toxin carries the risk of high urinary residuals, urinary tract infection and need to self catheterise. The use of vaginal oestrogens may improve OAB symptoms, but there is concern in those with a history of breast cancer. Studies have shown that the systemic absorption is negligible and does not increase the risk of recurrence. Expert Opinion: Improvement in assessing anticholinergic load is needed with the development of a universal drug scale. To avoid increasing load, Mirabegron or botulinum toxin can be used instead. There is no consensus of the use of prophylactic antibiotics when injecting botulinum toxin and at what residual to initiate self catheterisation. Despite evidence showing that the use of vaginal oestrogens is safe in those with a history of cancer, it is not fully supported by any health body. Further work is needed in those using aromatase inhibitors.

[Notice of expert for modality and prescriptions limits of local estrogenotherapy for urinairy inconfinence in women]

OBJECTIVE

To develop a consensus of experts on the use of local estrogens in female urinary incontinence.

MATERIAL AND METHOD

Following a formalized consensus method (DELPHI), a questionnaire was produced and sent to a first round and then to a second round of experts. The questionnaire consisted of proposals for recommendations for the use of local estrogens in the context of female urinary incontinence. The Survey Monkey^® survey software allowed the questionnaire to be distributed and the answers obtained to be analyzed.

RESULTS

Eight experts responded to the first round questionnaire. Seven formulations were deleted, 3 amended and 4 added to the first round questionnaire following expert advice. Twenty-six experts replied to the second round questionnaire, 24 of which were complete. Ten of the 21 proposals were approved at more than 80%, including five with strong agreement regarding the recognized benefit of local estrogens in urinary incontinence due to overactive bladder, the absence of data from the literature to demonstrate over-risk of hormone-dependent cancer under local estrogens and the need for follow-up of patients under this treatment. Six proposals were not the subject of a consensus and concerned the prescription modalities (maximum duration, effective minimum dose, prescription before surgery for incontinence).

CONCLUSION

Although local estrogens did not have regulatory approval in urinary incontinence, more than 80% of these experts recognized their benefit in the management of urinary incontinence in women with vulvo-vaginal atrophy, particularly in the case of urinary urge incontinence.

Management of menopausal symptoms in women with gynecologic cancers

OBJECTIVE

Women with gynecologic malignancies will be cured or may become long-term survivors. Management of menopausal symptoms is important in addressing their quality of life. We review the benefit and safety of hormone therapy use in these patients.

METHODS

MEDLINE was searched for studies on menopause management published in English through December of 2016.

RESULTS

Available data suggest that short-term use of hormone therapy in gynecologic cancer patients who do not have an estrogen-dependent malignancy do not adversely impact oncologic outcome and results in improvement of menopausal vasomotor and genitourinary symptoms. Evidence regarding safety of hormone therapy use in women with estrogen-dependent gynecologic malignances is currently lacking.

CONCLUSIONS

Candidates for hormone therapy in gynecologic oncology include women with menopausal symptoms diagnosed with low-grade, early-stage endometrial cancer, cervical, vulvar and vaginal cancer, and ovarian cancer.

Local hormone therapy for genitourinary syndrome of menopause in breast cancer patients: is it safe?

The genitourinary syndrome of menopause (GSM) is a frequent complaint among breast cancer (BC) survivors that lead to an important affection of their quality of life (QoL). Lifestyle measures such as smoking cessation or regular sexual activity are usually insufficient to significantly improve GMS and although therapies such as lubricants and polycarbophil moisturized gels are considered first-line therapies to alleviate symptoms of vulvovaginal atrophy, these non-hormonal options are not able to reverse atrophy once it occurs. Instead, this complaint is corrected by local estrogens. The estrogen vaginal treatment usually used to treat GSM, is an issue of concern in this group due to the possible negative effect over the BC outcomes. On the other hand, the worsening of QoL in these patients due to symptoms related to GSM can lead to discontinuation of hormone adjuvant therapies and therefore must be addressed properly. The goal of this review is to contribute to health care professionals to make an informed decision to care for their BC patients.

Vaginal Atrophy in Breast Cancer Survivors: Attitude and Approaches Among Oncologists

BACKGROUND

Vulvovaginal atrophy (VVA) is a relevant problem for breast cancer survivors (BCSs), in particular for those who receive aromatase inhibitors (AIs). We conducted a survey, to assess the attitude of oncologists toward the diagnosis and treatment of VVA in BCSs.

MATERIALS AND METHODS

In 2015, 120 computer-assisted Web interviews were performed among breast oncologists.

RESULTS

According to oncologists' perceptions, 60% of postmenopausal BCSs and 39.4% of premenopausal BCSs will suffer from VVA. Despite that none of the physicians considered VVA as a transient event or a secondary problem in BCSs, only half of the oncologists (48%) directly illustrated VVA to the patients as a possible consequence. Forty-one percent of the oncologists refer BCSs to gynaecologist to define VVA treatment, whereas 35.1% manages it alone. Nonhormonal treatments are preferred by most oncologists (71%). The main reason not to prescribe vaginal estrogen therapy in BCSs is the fear of increased cancer recurrence, the possible interference with tamoxifen, or AIs and the fear of medical litigation.

CONCLUSION

VVA is a relevant problem for BCSs. Great effort should be done to correctly inform health care providers about VVA problems and on the different possible available treatments.

Effect of Premature Menopause on Sexuality

Premature menopause, that is, menopause – spontaneous or iatrogenic – occurring at or before the age of 40 years, affects sexual identity, sexual function and sexual relationships. The woman's health, wellbeing and achievement of life's goals may be variably impaired. Factors modulating the individual's sexual outcome after premature menopause include: etiological heterogeneity of premature menopause and associated medical and sexual comorbidities; psychosexual vulnerability to premature menopause and associated infertility in survivors of childhood and adolescent cancers; impact of premature menopause on women's sexual identity, sexual function – particularly the biological basis of desire, arousal, orgasm and vaginal receptivity – and sexual relationships; partner-related factors; fertility issues; and preventive/therapeutic measures. Hormone therapy is indicated but long-term safety data are lacking. An interdisciplinary medical and psychosexual approach comprises appropriate counseling, fertility protection, when feasible, individualized hormone therapy and specific psychosexual treatment(s). Further research on fertility protection and the safety of long-term hormone therapy after premature menopause is needed.
