Menopause, due to loss of ovarian follicular activity without another pathological or physiological cause, typically occurs between the ages of 45 years and 56 years. During the menopausal transition, approximately 50% to 75% of women have hot flashes, night sweats, or both (vasomotor symptoms) and more than 50% have genitourinary symptoms (genitourinary syndrome of menopause [GSM]). Vasomotor symptoms typically last more than 7 years and GSM is often chronic. Efficacious treatments for women with bothersome vasomotor symptoms or GSM symptoms include hormonal and nonhormonal options. Systemic estrogen alone or combined with a progestogen reduces the frequency of vasomotor symptoms by approximately 75%. Oral and transdermal estrogen have similar efficacy. Conjugated equine estrogens (CEE) with or without medroxyprogesterone acetate (MPA) were the only hormonal treatments for which clinical trials were designed to examine cardiovascular events, venous thromboembolism, and breast cancer risk. Compared with placebo, the increased risk of stroke and venous thromboembolism associated with CEE (with or without MPA) and breast cancer (with use of CEE plus MPA) is approximately 1 excess event/1000 person-years. Low-dose CEE plus bazedoxifene is not associated with increased risk of breast cancer (0.25%/year vs 0.23%/year with placebo). Bioidentical estrogens approved by the US Food and Drug Administration (with identical chemical structure to naturally produced estrogens, and often administered transdermally) also are available to treat vasomotor symptoms. For women who are not candidates for hormonal treatments, nonhormonal approaches such as citalopram, desvenlafaxine, escitalopram, gabapentin, paroxetine, and venlafaxine are available and are associated with a reduction in frequency of vasomotor symptoms by approximately 40% to 65%. Low-dose vaginal estrogen is associated with subjective improvement in GSM symptom severity by approximately 60% to 80%, with improvement in
There is increasing attention about managing the adverse effects of adjuvant therapy (Chemotherapy and anti-estrogen treatment) for breast cancer survivors (BCSs). Vulvovaginal atrophy (VVA), caused by decreased levels of circulating estrogen to urogenital receptors, is commonly experienced by this patients. Women receiving antiestrogen therapy, specifically aromatase inhibitors, often suffer from vaginal dryness, itching, irritation, dyspareunia, and dysuria, collectively known as genitourinary syndrome of menopause (GSM), that it can in turn lead to pain, discomfort, impairment of sexual function and negatively impact on multiple domains of quality of life (QoL). The worsening of QoL in these patients due to GSM symptoms can lead to discontinuation of hormone adjuvant therapies and therefore must be addressed properly. The diagnosis of VVA is confirmed through patient-reported symptoms and gynecological examination of external structures, introitus, and vaginal mucosa. Systemic estrogen treatment is contraindicated in BCSs. In these patients, GSM may be prevented, reduced and managed in most cases but this requires early recognition and appropriate treatment, but it is normally undertreated by oncologists because of fear of cancer recurrence, specifically when considering treatment with vaginal estrogen therapy (VET) because of unknown levels of systemic absorption of estradiol. Lifestyle modifications and nonhormonal treatments (vaginal moisturizers, lubricants, and gels) are the first-line treatment for GSM both in healthy women as BCSs, but when these are not effective for symptom relief, other options can be considered, such as VET, ospemifene, local androgens, intravaginal dehydroepiandrosterone (prasterone), or laser therapy (erbium or CO2 Laser). The present data suggest that these therapies are effective for VVA in BCSs; however, safety remains controversial and a there is a major concern with all of these treatments. We review current evidence for various
Genitourinary syndrome of menopause (GSM) occurs in approximately 50% of menopausal women but is both underrecognized and undertreated despite numerous treatment options. Vaginal dryness, irritation, dyspareunia, urinary frequency, and urinary urgency are some of the more common symptoms that can have a negative effect on women's lives and relationships. Treatment options can include over-the-counter moisturizers and lubricants that can be composed of water or silicone or have an oil base. However, women and health care providers need be aware of the effects of excipients in these products so that the therapy does not cause vaginal irritation. US Food and Drug Administration (FDA)-approved treatment options include vaginally administered estrogen products as well as dehydroepiandrosterone (prasterone) and the selective estrogen receptor modulator ospemifene. The prescription options have proven efficacy and safety and can be considered for use by women with a history of cancer following collaboration with the oncologist. Despite the FDA warning that recommends vaginal lasers not be used for vaginal rejuvenation, vaginal lasers have also been used as a treatment for GSM, but studies on their safety are limited. This article reviews GSM, including its impact, diagnosis, and treatment.
