In November 2022, the findings of the Avoiding Late Diagnosis of Ovarian cancer (ALDO) study were published. Subsequent media coverage suggested that investigators had found a safe alternative to risk-reducing bilateral salpingoophorectomy (rrBSO) in patients with pathogenic BRCA1 and BRCA2 germline mutations who chose to decline or defer risk-reducing surgery. Unfortunately, this media coverage was largely misleading. Specifically, in the ALDO trial, 4 of 6 patients found to have ovarian cancer by the ALDO screening methodology were diagnosed with advanced-stage disease. The primary endpoint of the ALDO study was the rate of complete surgical cytoreduction, rather than stage at diagnosis or overall survival, which is an inappropriate surrogate for benefit in a population at risk of ovarian cancer.The ALDO trial again demonstrates that screening women at high-risk of ovarian cancer should not be considered a safe alternative to risk-reducing surgery, and can lead to false reassurance and the development of preventable cases of ovarian cancer. While we should continue to investigate new screening options, future efforts should largely focus on why patients decline rrBSO in the first place and how we can pivot our efforts to better address concerns related to rrBSO, including sequelae of surgical menopause. Furthermore, as we continue to understand the role of the fallopian tube in the epithelial ovarian cancer (EOC) disease process, we must identify the role of salpingectomy alone in prevention of EOC.
