Assessing a new approach to reduce ovarian cancer risk in high-risk women
Official title: TUBectomy With Delayed Oophorectomy as Alternative for Risk-reducing Salpingo-oophorectomy in High Risk Women to Assess the Safety of Prevention: TUBA-WISP II Study.
Run by University Medical Center Nijmegen · NCT04294927 · Data updated 2026-11-12
This study is testing a new surgery to see if removing just the fallopian tubes first can help women at high risk for ovarian cancer lower their chances of getting the disease while avoiding some of the side effects of more traditional surgery.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include women aged 25-50 with a pathogenic BRCA1, BRCA2, RAD51C, RAD51D, or BRIP1 mutation who have completed childbearing.
✕Probably not a fit
Patients who are postmenopausal or have a personal history of ovarian, fallopian tube, or peritoneal cancer may not benefit from this study.

What this trial studies
This project evaluates the safety and effectiveness of risk-reducing salpingectomy with delayed oophorectomy as an alternative to the standard risk-reducing salpingo-oophorectomy in women with BRCA1/2 and other gene mutations. The study aims to determine the long-term effects of this innovative strategy on ovarian cancer incidence, given the high mortality rates associated with ovarian cancer and the limitations of current surveillance methods. Participants will undergo a surgical procedure to remove the fallopian tubes, with oophorectomy performed at a later date, allowing for a potential reduction in cancer risk while minimizing immediate menopause-related complications.
Why it matters
Potential benefit: If successful, this approach could significantly lower the risk of ovarian cancer in high-risk women while reducing the immediate health impacts associated with traditional preventive surgeries.
How similar studies have gone: While the approach of risk-reducing salpingectomy with delayed oophorectomy is innovative, similar studies have suggested that most high-grade serous ovarian cancers originate in the fallopian tubes, indicating potential for success.
