Severity and duration of menopausal symptoms after risk-reducing salpingo-oophorectomy

Abstract

Objectives: To reduce the risk of ovarian cancer, women with BRCA1/2 mutations are advised to undergo risk-reducing salpingo-oophorectomy (RRSO) at a premenopausal age. Premenopausal RRSO results in acute menopause and is associated with various menopausal symptoms. This study investigates the severity and duration of subjective menopausal symptoms after premenopausal RRSO and associated factors.

Methods: We included 199 women who had undergone RRSO before age 52 in this cross-sectional study. The Menopause Rating Scale (MRS) was used to measure the level of psychological, somato-vegetative and urogenital symptoms (no/little, mild, moderate, or severe). Uni- and multivariate logistic regressions were performed to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for having moderate or severe symptoms as compared to having no or mild symptoms. Duration of symptoms was investigated by calculating the time since RRSO.

Results: Sixty-nine percent (137/199) of the included women reported moderate or severe symptoms on the MRS, a mean of 7.9 years after RRSO. Fifty-seven percent (94/137) of these women reported severe urogenital symptoms, and about one-quarter reported severe psychological and/or somato-vegetative symptoms. Only psychological symptoms tended to improve over time (>=10 years). A personal history of breast cancer was independently associated with having moderate or severe menopausal symptoms (OR = 3.4; 95%CI = 1.6-7.1).

Conclusions: The majority of women report moderate or severe menopausal symptoms, even 10 years after surgical menopause, and breast cancer survivors especially. To improve quality of life, follow-up care after RRSO should focus on these symptoms and be accessible for many years after RRSO.
