Impact of risk-reducing salpingo-oophorectomy on lipid determinants, HbA1c and CRP

Abstract

Objective Risk-reducing salpingo-oophorectomy (RRSO) is advised before 40–45 years of age for BRCA1/2 mutation carriers. This study describes the effect of RRSO on lipid determinants, hemoglobin A1c (HbA1c) and C-reactive protein (CRP). Methods A total of 142 women with increased risk of ovarian cancer were included, 92 premenopausal and 50 postmenopausal. Serum levels of low-density lipoprotein (LDL)-cholesterol, high-density lipoprotein (HDL)-cholesterol and total cholesterol, triglycerides, HbA1c and CRP were determined at three points in time: before (T0) and 6 weeks (T1) and 7 months (T2) following RRSO. The Hot Flush Rating Scale was administered at the same time points. Results In premenopausal women, levels of HDL-cholesterol, the cholesterol ratio and HBA1c increased significantly over time, although still staying within the reference range. In this group, hot flushes increased over time (p < 0.001). In postmenopausal women, no significant changes were observed following RRSO. At T2, serum LDL-cholesterol, triglycerides, HbA1c and CRP were significantly lower in premenopausal women compared to postmenopausal women, whereas HDL was increased. Conclusions Seven months after RRSO, the lipid profile in premenopausal women had changed, although still staying within the reference range. For postmenopausal women, we did not observe any significant changes. Our results do not suggest a worsening of cardiovascular risk within 7 months of RRSO.
