Metabolic syndrome after risk-reducing salpingo-oophorectomy in women at high risk for hereditary breast ovarian cancer: a controlled observational study.

Surgical menopause may increase the risk of cardiovascular diseases (CVDs). The aim of this study was to determine the risk of metabolic syndrome in women who had undergone risk-reducing salpingo-oophorectomy (RRSO) because of increased risk of hereditary breast ovarian cancer (HBOC). A sample of 326 (65% of invited) women at risk of HBOC who had undergone RRSO was compared to 679 women from the general population. Mean follow-up after surgery was 6.5 years (standard deviations [SD] 4.4). RRSO was significantly associated with metabolic syndrome according to the 2005 National Cholesterol Education Program Adult Treatment Panel III criteria (odds ratio [OR] 2.46 [95% confidence interval (CI) 1.63, 3.73]) and according to the International Diabetes Federation criteria (OR 2.49 [CI 1.60, 3.88]), as were increasing age and body mass index (BMI). RRSO in women at risk of HBOC is significantly associated with the metabolic syndrome, and the follow-up after RRSO should take these findings into consideration.
