New Data: Vaginal Estrogen Use in Breast CA Survivors

With an estimated 3.8 million breast cancer survivors in the United States, OBGYNs and other women's healthcare providers often are on the front lines of addressing survivorship issues, including the hypoestrogenic-related adverse effects of cancer therapies or early menopause in survivors. 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. The term genitourinary syndrome of menopause (GSM) is the term used to describe to a constellation of symptoms that relate to hypoestrogenic effects on the genital epithelium, such as genital dryness, burning, and irritation; potential downstream effects of vulvar and vaginal atrophy such as dyspareunia; urinary symptoms such as urgency or dysuria; and recurrent urinary tract infections. Is vaginal estrogen or estrogen-like therapies safe in these patients? What about in those using aromatase inhibitors? A new Meta-Analysis (AJOG) provides insights. Listen in for details.
