Evaluating a new surgical approach to reduce ovarian cancer risk in high-risk women

Official title: Risk Reducing Salpingectomy With Delayed Oophorectomy as an Alternative to Risk- Reducing Salpingo-oophorectomy in High Risk-Women to Assess the Safety of Prevention - US Cohort Study

Run by M.D. Anderson Cancer Center · NCT05287451 · Data updated 2026-11-12

This study is testing a new surgery to see if removing fallopian tubes now and delaying ovary removal later can help women with BRCA1/2 gene mutations lower their risk of ovarian cancer just as well as the usual surgery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are premenopausal women aged 25-50 with documented deleterious mutations in BRCA1, BRCA2, BRIP1, RAD51C, or RAD51D.

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 study aims to assess 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 gene mutations. The research will focus on whether delaying oophorectomy until the ages of 40-45 for BRCA1 and 45-50 for BRCA2 can maintain a similar level of protection against high-grade serous ovarian cancer compared to the current standard procedure. Participants will be premenopausal women who have completed childbearing and have at least one fallopian tube. The study will also evaluate the incidence of (pre)malignant findings and other related health outcomes.

Why it matters

Potential benefit: If successful, this approach could allow high-risk women to delay menopause while still effectively reducing their risk of ovarian cancer.

How similar studies have gone: Other studies have explored similar surgical approaches, but this specific method of delayed oophorectomy in high-risk women is relatively novel.

Inclusion Criteria:

In order to be eligible to participate in this study, a subject must meet all of the following criteria:

1. Premenopausal women with a documented deleterious mutation in BRCA1, BRCA2, BRIP1, RAD51C, PALB2 and/or RAD51D gene germline mutation.
2. Age 25-40 years for BRCA1 mutation carriers, 25-45 years for BRCA2 and 30-50 years for BRIP1, RAD51C, RAD51D, and PALB2.

   * The highest risk for cancer is mediated by the BRCA mutation. If a patient has multiple mutations, eligibility will be based on BRCA mutation.
3. No longer requires fallopian tubes for natural childbearing. Future plans for IVF are acceptable.
4. Presence of at least one fallopian tube.
5. Participants may have a personal history of non-ovarian malignancy.
6. Informed consent must be obtained and documented.

Exclusion Criteria:

A potential subject who meets any of the following criteria will be excluded from participation in this study:

1. Postmenopausal status (natural menopause or due to (cancer) treatment)

   * A postmenopausal state is defined as no menses for 12 months without an alternative medical cause.
   * A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy (HRT). However, in the absence of 12 months of amenorrhea, confirmation per the local standard of care can be considered.
2. Wish for second stage RRO within two years after RRS (if clear at enrollment)
3. Legally incapable
4. Prior bilateral salpingectomy
5. A personal history of ovarian, fallopian tube, or peritoneal cancer
6. Current clinicals signs, diagnosis, or treatment for malignant disease. Aromatase Inhibitors, Tamoxifen, and Selective Estrogen Receptor Modulators (SERM) are allowed.
