This clinical trial evaluates how well two surgical procedures (bilateral salpingectomy and bilateral salpingo-oophorectomy) work in reducing the risk of ovarian cancer for individuals with BRCA1 mutations. Bilateral salpingectomy involves the surgical removal of fallopian tubes, and bilateral salpingo-oophorectomy involves the surgical removal of both the fallopian tubes and ovaries. This study may help doctors determine if the two surgical procedures are nearly the same for ovarian cancer risk reduction for women with BRCA1 mutations.
Individuals 35-50 years of age, inclusive
Patients who will undergo risk-reducing salpingo-oophorectomy (RRSO) (for the BSO arm) and patients who have declined or elected to defer BSO after proper counselling to clearly explain the standard of care for BRCA1 mutation carriers and are undergoing salpingectomy (for the BLS arm with delayed oophorectomy arm). Concurrently planned hysterectomy with either arm is permitted
At least one intact ovary and fallopian tube is in situ at the time of counseling, consent, and registration. Prior hysterectomy is allowed provided it did not include bilateral salpingectomy. Prior tubal ligation is allowed if one ovary and fallopian tube (with fimbria not removed) are present
Positive Clinical Laboratory Improvement Act (CLIA)-approved test results for pathogenic or likely pathogenic germline BRCA1 mutation in the patient. Documentation of the result is required
Individuals with a history of any prior cancer who have received cytotoxic chemotherapy within the past 30 days or radiotherapy to abdomen or pelvis at any prior time. Endocrine therapy or maintenance ERBB2/HER2 targeted therapy is allowed. Maintenance immune checkpoint inhibitor therapy is allowed. Maintenance therapy with PARP in inhibitor is allowed.
Prior history of ovarian cancer, including low malignant potential neoplasms (LMP), primary peritoneal carcinoma, or fallopian tube carcinoma
Patients medically unfit for the planned surgical procedure
Patients with abnormal screening tests (pelvic ultrasound, pelvic MRI, CA-125) suspicious for occult or gross pelvic malignancy within the past 180 days
