A Non-Randomized Prospective Clinical Trial Comparing the Non-Inferiority of Salpingectomy to Salpingo-Oophorectomy to Reduce the Risk of Ovarian Cancer Among BRCA1 Carriers [SOROCk]
Overview
This trial studies how well two surgical procedures (bilateral salpingectomy and bilateral salpingo-oophorectomy) work in reducing the risk of ovarian cancer for women 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.
Key Inclusion Criteria
For a patient to be eligible for participation in this study, all of the following criteria must apply.
- Patients who have declined or elected to defer risk-reducing salpingo-oophorectomy (RRSO) after proper counselling to clearly explain the standard of care for BRCA1 mutation carriers (for the BLS with delayed oophorectomy arms) or patients who are undergoing RRSO (for the RRSO arm)
- At least one intact ovary and fallopian tube
- Positive Clinical Laboratory Improvement Act (CLIA)-approved test results for pathogenic or likely pathogenic germline BRCA1 mutation in the patient herself. Documentation of the result is required
- Premenopausal; defined as < 12 months of amenorrhea. However, for those patients with >= 12 months of amenorrhea who may be pre-menopausal or patients with a prior hysterectomy with at least one retained ovary/tube, levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), and in the premenopausal range per local institutional standards will be acceptable
- Concurrently planned or prior hysterectomy is permitted as long as at least one fallopian tube and one ovary had been retained
- Transvaginal ultrasound (TVUS) and CA-125 within 180 days of registration
- The patient or a legally authorized representative must provide study-specific informed consent prior to study entry
- Patient must have negative urine pregnancy test within 14 days prior to registration based on local institutional policies
Key Exclusion Criteria
A patient will not be eligible for participation in this study if any of the following criteria apply.
- Women with a history of any prior cancer who have received chemotherapy within the past 12 months, hormonal therapy in the past 90 days, or radiotherapy to abdomen or pelvis at any prior time
- 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 (TVUS, CA-125) suspicious for occult or gross pelvic malignancy or neoplasm within the past 180 days
- An abnormal TVUS is defined as morphologic or structural variations suspicious for ovarian malignancy or complex cystic lesions (simple cysts < 5 cm in maximal diameter are not exclusionary)
- An abnormal CA-125 is defined as a level > 50 U/ml in this study population of premenopausal women if they are not current users of oral contraceptives; an abnormal CA-125 is defined as a level > 40 U/ml for premenopausal women who are current users of oral contraceptives
- Women who are currently pregnant or plan to become pregnant in the future
