Abstract

Purpose: Risk-reducing salpingo-oophorectomy (RRSO) lowers mortality from ovarian/tubal and breast cancers among BRCA1/2 mutation carriers. Uncertainties persist regarding potential benefits of RRSO among high-risk noncarriers, optimal surgical age, and anatomic origin of clinically occult cancers detected at surgery. To address these topics, we analyzed surgical treatment arm results from Gynecologic Oncology Group Protocol-0199 (GOG-0199), the National Ovarian Cancer Prevention and Early Detection Study.

Participants and Methods: This analysis included asymptomatic high-risk women age ≥ 30 years who elected RRSO at enrollment. Women provided risk factor data and underwent preoperative cancer antigen 125 (CA-125) serum testing and transvaginal ultrasound (TVU). RRSO specimens were processed according to a standardized tissue processing protocol and underwent central pathology panel review. Research-based BRCA1/2 mutation testing was performed when a participant's mutation status was unknown at enrollment. Relationships between participant characteristics and diagnostic findings were assessed using univariable statistics and multivariable logistic regression.

Results: Invasive or intraepithelial ovarian/tubal/peritoneal neoplasms were detected in 25 (2.6%) of 966 RRSOs (BRCA1 mutation carriers, 4.6%; BRCA2 carriers, 3.5%; and noncarriers, 0.5%; P<.001) In multivariable models, positive BRCA1/2 mutation status (P =.0056), postmenopausal status (P =.0023), and abnormal CA-125 levels and/or TVU examinations (P>.001) were associated with detection of clinically occult neoplasms at RRSO. For 387 women with negative BRCA1/2 mutation testing and normal CA-125 levels, findings at RRSO were benign.

Conclusion: Clinically occult cancer was detected among 2.6% of high-risk women undergoing RRSO BRCA1/2 mutation, postmenopausal status, and abnormal preoperative CA-125 and/or TVU were associated with cancer detection at RRSO. These data can inform management decisions among women at high risk of ovarian/tubal cancer.
