Vaginal epithelial atrophic changes (A), versus healthy genital tissue (B), examined internally using a vaginal speculum or externally (using vulvoscopy when warranted), can indicate genitourinary syndrome of menopause/vulvovaginal atrophy in a postmenopausal woman.
Dyspareunia and low sexual desire in a breast cancer survivor
Dr. Levy: In this case, a 36-year-old woman with BRCA1−positive breast cancer has vaginal dryness, painful intercourse, and lowered sexual interest since her treatment, which included chemotherapy after bilateral mastectomies. She has a bilateral salpingo-oophorectomy(BSO) scheduled for primary prevention of her ovarian cancer risk.
Dr. Kingsberg, what is important for you to know to help guide case management?
Dr. Kingsberg: This woman is actually presenting with 2 sexual problems: dyspareunia, which is probably secondary to VVA or GSM, and low sexual desire. Key questions are: 1) When was symptom onset--acquired after treatment or lifelong? 2) Did she develop the dyspareunia and as a result of having pain during sex lost desire to have sex? Or, did she lose desire and then, without it, had no arousal and therefore pain with penetration developed? It also could be that she has 2 distinct problems, VVA and hypoactive sexual desire disorder (HSDD), in which case you need to think about treating both. Finally, we do not actually know if she is having penetrative intercourse or even if she has a partner.
A vulvovaginal exam would give clues as to whether she has VVA, and hormone levels would indicate if she now has chemo-induced menopause. If she is not in menopause now, she certainly is going to be with her BSO. The hormonal changes due to menopause actually can be primarily responsible for both the dyspareunia and HSDD. Management of both symptoms really needs to be based on shared decision making with the patient--with which treatment for which conditions coming first, based on what is causing her the most distress.
I would encourage this woman to treat her VVA since GSM does have long-term physiologic consequences if untreated. The American College of Obstetricians and Gynecologists (ACOG) recommends nonhormonal treatments as first-line treatments, with vaginal estrogen considered if these therapies fail.3 If lubricants and moisturizers and other nonhormonal options are not sufficient, you could consider local estrogen, even though she is a breast cancer survivor, as well as ospemiphene.
If she is distressed by her loss of sexual desire, you can choose to treat her for HSDD. Flibanserin is the first FDA-approved treatment for HSDD. It is only approved in premenopausal women, so it would be considered off-label use if she is postmenopausal (even though she is quite young). You also could consider exogenous testosterone off-label, after consulting with her oncologist.
In addition to the obvious physiologic etiology of her pain and her low desire, the biopsychosocial aspects to consider are: 1) changes to her body image, as she has had bilateral mastectomies, 2) her anxiety about the cancer diagnosis, and 3) concerns about her relationship if she has one--her partner's reactions to her illness and the quality of the relationship outside the bedroom.
Dr. Iglesia: I am seeing here in our nation's capital a lot of advertisements for laser therapy for GSM. I caution women about this because providers are charging a lot of money for this therapy when we do not have long-term safety and effectiveness data for it.
Our group is currently conducting a randomized controlled trial, looking at vaginal estrogen cream versus laser therapy for GSM here at Medstar Health--one of the first in the country as part of a multisite trial. But the North American Menopause Society (NAMS) has come out with a pretty strong statement,4 as has ACOG,5 on this therapy, and I caution people about overzealously offering a very costly procedure targeted to a very vulnerable population, especially to women with personal histories of estrogen-sensitive cancers.
Dr. Krychman: I agree. Very often cancer patients are preyed upon by those offering emerging unproven technologies or medications. We have to work as a coordinated comprehensive team, whether it's a sexual medicine expert, psychologist, urogynecologist, gynecologist, or oncologist, and incorporate the patient's needs and expectations and risk tolerance coupled with treatment efficacy and safety.
Dr. Levy: This was a complex case. The biopsychosocial model is critical here. It's important that we are not siloes in our medical management approach and that we try to help this patient embrace the complexity of her situation. It's not only that she has cancer at age 36; there is a possible guilt factor if she has children and passed that gene on.
Another point that we began to talk about is the fact that in this country we tend to be early adopters of new technology. In our discussion with patients, we should focus on what we know and the risk of the unknowns related to some of the treatment options. But let's discuss lasers a little more later on.
