544 Patients with CHEK2 mutation followed up in a hereditary gynaecological cancer unit

Abstract

distinguish in from p53 signatures, STIL and invasive carcinoma. All statistical analysis was performed by Stata/IC 13.0 for Windows. Result(s)* A total of 115 were included. Of them, 50.4% had BRCA 1 mutation and 49.6% BRCA 2 mutation. Mean (+/-Standard deviation, SD) age at surgery was 49.2 (5.8) years. Of note, 40.9% underwent surgical menopause. The median Ca-125 value prior to surgery was 29.4 u/L. Adnexal findings in presurgery ultrasound were normal (104, 90.4%) or benign cyst (11, 17.4%). Also, endometrial polyps were found in 3.5% (3) of patients. Pathologic exam showed STIC in 5 (4.5%) patients and invasive ovarian carcinoma in 1 (0.9%). Conclusion* Currently, RRSO is the only tool to reduce the risk of ovarian cancer in BRCA mutations carriers. However, the incidence of STIC after RRSO is not very high.
