CASE Genitourinary syndrome of menopause (GSM) in a 55-year-old woman
A 55-year-old widow is beginning a new relationship. She has not had partnered sexual activity for several years, but she recently has begun a relationship. She describes pain with attempted penetration with her new partner. Her last menstrual period was 3 years ago and she has experienced very minor menopausal symptoms, which are not bothersome. On examination, the vulva and vagina are pale, with thin epithelium and absent rugae. The tissue lacks elasticity. A virginal speculum is needed to visualize the cervix.
How would you go about deciding which of the many options for management of GSM you will recommend for this patient? What do you weigh as you consider DHEA versus estrogen and topical versus oral therapy?
JoAnn V. Pinkerton, MD: Vulvovaginal atrophy (VVA), part of GSM, is associated with postmenopausal estrogen deficiency and includes the signs and symptoms seen on this patient's physical exam: vaginal narrowing, pallor, loss of elasticity, as well as pain with intercourse.6 Estrogen therapy is the most effective treatment for vaginal atrophy.13 Since she does not have significant menopausal symptoms, low-dose vaginal estrogen preparations are effective and generally safe treatments for VVA; these include creams, tablets containing estradiol or conjugated equine estrogen (CEE), and a low-dose vaginal estradiol ring--all available at doses that result in minimal systemic absorption.
Choice is usually made based on patient desire and likely adherence. If the patient prefers nonestrogen therapies that improve VVA and have been approved for relief of dyspareunia in postmenopausal women, I would discuss with the patient the oral selective estrogen receptor modulator ospemifene,14 and the new intravaginal DHEA suppositories, prasterone.15 Ospemifene is taken daily as an oral tablet, has a small risk of blood clots, and is my choice for women who do not need systemic hormone therapy and prefer to avoid vaginal therapy.
Andrew M. Kaunitz, MD: GSM is prevalent in menopausal women and, if not treated, causes progressive vaginal dryness and sexual discomfort. When the main indication for hormonal management in a menopausal woman is GSM (as opposed to treatment of vasomotor symptoms or prevention of osteoporosis), the treatment of choice is low-dose local vaginal estrogen, ospemifene, or prasterone (DHEA). Prasterone is a vaginally administered nonestrogen steroid that was approved by the FDA to treat dyspareunia associated with GSM. DHEA is an endogenous inactive steroid that is converted locally into androgens and estrogens; one vaginal insert is placed nightly.16,17
This 55-year-old widow has not been sexually active for some time. The facts that attempted penetration was painful and only an ultrathin (virginal) speculum could be used for examination indicate that contraction of the pelvic floor muscles is likely present. Simply starting medical management may not lead to comfortable/successful penetrative sex for this woman. In addition to medical management, she would likely benefit from referral for physical therapy. Using dilators and other strategies, along with the positive impact that medical management will have on the vaginal mucosa, a woman's physical therapist can work with this patient to help the pelvic floor muscles relax and facilitate comfortable penetrative sex.
James A. Simon, MD: With only minor vasomotor symptoms, I would assess the other potential benefits of a systemic therapy. These might include cardiovascular risk reduction (systemic estrogens or estrogens/progesterone in some), breast cancer risk reduction (some data suggesting ospemifene can accomplish this), osteoporosis prevention (systemic estrogens and estrogen/androgens), etc. If there is an option for a treatment to address more than one symptom, in this case GSM, assessing the risks/benefits of each of these therapies should be estimated for this specific patient.
If there are no systemic benefits to be had, then any of the local treatments should be helpful. As there are no head-to-head comparisons available, local estrogen cream, tablets, rings, local DHEA, or systemic ospemifene each should be considered possible treatments. I also feel this patient may benefit from supplementary self-dilation and/or physical therapy.

CASE Dyspareunia and vasomotor symptoms in a 42-year-old breast cancer survivor
A 42-year-old woman with a BRCA1 mutation has undergone prophylactic mastectomies as well as hysterectomy with bilateral salpingo-oophorectomy. She reports mild to moderate hot flashes and bothersome vaginal dryness and dyspareunia. Examination confirms GSM.
Would you advise systemic hormone therapy for this patient? What would your recommendation be for management of her GSM symptoms?
Dr. Simon: While one's gut reaction would be to avoid systemic estrogen therapy in a patient with a BRCA1 mutation, the scientific information confirming this fear is lacking.18 Such patients may benefit significantly from systemic estrogen therapy (reduced risk of cardiovascular disease and cognitive decline, etc.), and with both breasts and both ovaries removed, estrogen's breast cancer risks, if any in this population, are largely avoided. The patient also may benefit from additional local therapy with either estrogens or DHEA.
Dr. Kaunitz: Due to her high lifetime risk of breast and ovarian cancer, this woman has proceeded with risk-reducing breast and gynecologic surgery. As more BRCA mutation carriers are being identified and undergo risk-reducing bilateral mastectomy (usually with reconstruction) and salpingo-oophorectomy, clinicians and mutation carriers more frequently face decisions regarding use of systemic hormone therapy.
Mutation carriers who have undergone bilateral risk-reducing mastectomy experience a very low baseline future risk for breast cancer; accordingly, concerns regarding this disease should not prevent use of systemic hormone therapy. Furthermore, without hormone replacement, induced menopause in women this age is associated with an elevated risk of osteoporosis, persistent vasomotor symptoms, cardiovascular disease, stroke, mood changes, dementia, Parkinson disease, and overall mortality. Recognizing the safety of estrogen therapy in this setting, this 42-year-old BRCA1 mutation carrier can initiate estrogen therapy. Standard dose estrogen therapy refers to oral estradiol 1.0 mg, conjugated equine estrogen 0.625 mg,or transdermal estradiol 0.05 mg. In younger women like this 42-year-old with surgically induced menopause, higher than standard replacement doses of estrogen are often appropriate.17
Due to concerns the hormone therapy might further increase future risk of breast cancer, some mutation carriers may delay or avoid risk-reducing bilateral salpingo-oophorectomy, a potentially lifesaving surgery which reduces not only future risk of ovarian cancer but also future risk for breast cancer.
Among mutation carriers with intact breasts, several studies address risk of breast cancer with use of systemic hormone therapy. Although limited in numbers of participants and years of follow-up, in aggregate, these studies provide reassurance that short-term use of systemic hormone therapy does not increase breast cancer risk in women with BRCA1 or BRCA2 mutations and intact breasts.19
Dr. Pinkerton: For this woman with early surgical menopause and hysterectomy, estrogen therapy could improve her vasomotor symptoms and decrease her risk of bone loss and GSM.17 In the Women's Health Initiative trial, there were 7 fewer breast cancers per 10,000 women-years in the estrogen-onlyarm.20 Observational studies suggest that hormone therapy, when given to the average age of menopause, decreases the risks of heart disease, Parkinson disease, and dementia.21 Limited observational evidence suggests that hormone therapy use does not further increase risk of breast cancer in women following oophorectomy for BRCA1 or BRCA2 gene mutation.22
The absolute risks observed with hormone therapy tended to be small, especially in younger, healthy women. Systemic hormone therapy could treat her hot flashes and her GSM symptoms and potentially decrease health risks associated with premature estrogen deficiency. Nonestrogen therapies for hot flashes include low-dose antidepressants, gabapentin, and mind-body options, such as cognitive behavioral therapy and hypnosis, but these would not decrease her health risks or treat her GSM.
If she only requests treatment of her GSM symptoms, she would be a candidate for low-dose vaginal estrogen therapy, given as a cream, tablet, or ring depending on her choice. I would not choose ospemifene as my first choice as she is having hot flashes, and there are no data yet on the drug's health benefits in early menopause. If she prefers nonestrogen vaginal therapy, the new intravaginal DHEA might be a good choice as both estrogen and testosterone are increased locally in the vagina while hormone levels remain in the postmenopausal range. There is no boxed warning on the patient insert, although safety in women with breast cancer or in those with elevated risk of breast cancer has not been tested.
