Women who undergo bilateral salpingo-oophorectomy (BSO) for various indications prior to menopause experience a rapid decline in ovarian hormone levels and consequent vasomotor and other menopausal symptoms. In addition, the resulting estrogen deprivation is associated with such long-term adverse outcomes as osteoporosis and cardiovascular morbidity.
OBG Management convened a roundtable with 3 experts who discussed health considerations in women who have undergone BSO prior to the age of natural menopause1 to further explore the issues involved in managing hormone therapy (HT) in these patients. Stephanie Faubion, MD, MBA, NCMP, moderated the exchange.
Surgical vs natural menopause
Stephanie Faubion, MD, MBA, NCMP: Since the Women’s Health Initiative study was published in 2002,2 many clinicians have been fearful of using systemic HT in menopausal women, and HT use has declined dramatically such that only about 4% to 6% of menopausal women are now receiving systemic HT. Importantly, however, a group of younger menopausal women also are not receiving HT, and that is women who undergo BSO before they reach the average age of menopause, which in the United States is about age 52; this is sometimes referred to as surgical menopause or early surgical menopause. Early surgical menopause has different connotations for long-term health risks than natural menopause at the average age, and we are here to discuss these health effects and their management.
My name is Stephanie Faubion, and I am a women’s health internist and the Chair of the Department of Medicine at Mayo Clinic in Jacksonville, Florida, and Director of Mayo Clinic Women’s Health. I am here with 2 of my esteemed colleagues, Dr. Andrew Kaunitz and Dr. Ekta Kapoor.
Andrew M. Kaunitz, MD, NCMP: Hello, I am an ObGyn with the University of Florida College of Medicine in Jacksonville, with particular interests in contraception, menopause, and gynecologic ultrasonography.
Ekta Kapoor, MBBS, NCMP: And I am an endocrinologist at Mayo Clinic in Rochester with a specific interest in menopause and hormone therapy. I am also the Assistant Director for Mayo Clinic Women’s Health.
Higher-than-standard estrogen doses needed in younger menopausal women
Dr. Faubion: Let’s consider a couple of cases so that we can illustrate some important points regarding hormone management in women who have undergone BSO before the age of natural menopause.
Our first case patient is a woman who is 41 years of age and, because of adenomyosis, she will undergo a hysterectomy. She tells her clinician that she is very concerned about ovarian cancer risk because one of her good friends recently was diagnosed with ovarian cancer, and together they decide to remove her ovaries at the time of hysterectomy. Notably, her ovaries were healthy.
The patient is now menopausal postsurgery, and she is having significant hot flashes and night sweats. She visits her local internist, who is concerned about initiating HT. She is otherwise a healthy woman and does not have any contraindications to HT. Dr. Kaunitz, what would you tell her internist?
Dr. Kaunitz: We are dealing with 2 different issues in terms of decision making about systemic HT for this 41-year-old who has undergone BSO. First, as you mentioned, Dr. Faubion, she has bothersome hot flashes, or vasomotor symptoms. Unless there are contraindications, systemic HT would be appropriate. Although I might start treatment at standard doses, and the accompanying TABLE depicts standard doses for the 2 most common oral estrogen formulations as well as transdermal estradiol, it’s important to recognize that younger menopausal women often will need to use higher-than-standard doses.
For example, for a 53-year-old woman who has been menopausal for a year or 2 and now has bothersome symptoms, I might start her on estradiol 1 mg tablets with progestin if a uterus is present. However, in this 41-year-old case patient, while I might start treatment at a standard dose, I would anticipate increasing to higher doses, such as 1.5 or 2 mg of daily estradiol until she feels her menopausal symptoms are adequately addressed.
Dr. Faubion: It is important to note that sometimes women with early BSO tend to have more severe vasomotor symptoms. Do you find that sometimes a higher dose is required just to manage symptoms, Dr. Kaunitz?
Dr. Kaunitz: Absolutely, yes. The decision whether or not to use systemic HT might be considered discretionary or elective in the classic 53-year-old woman recently menopausal with hot flashes, a so-called spontaneously or naturally menopausal woman. But my perspective is that unless there are clear contraindications, the decision to start systemic HT in the 41-year-old BSO case patient is actually not discretionary. Unless contraindications are present, it is important not only to treat symptoms but also to prevent an array of chronic major health concerns that are more likely if we don’t prescribe systemic HT.
