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)

Brief description of study
What is this study about?
This study is investigating 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
THIS STUDY IS ENROLLING BY INVITATION ONLY - Consistent with most oncology trials, patients are not actively “recruited,” but are screened by their physician for appropriate clinical trial(s) at the time of their routine clinic visit. Occasionally, a patient may be a self-referral or physician referral, but are still screened for appropriate clinical trials at the time of their routine clinic visit. PI and staff may send copies of relevant consent forms to these patients to look over prior to actually consenting or enrolling them. This may take place at the patient's visit at which the consent is presented or the patient's next visit to the outpatient hematology/oncology clinic.

Detailed description of study
What happens during study participation?
- Patients undergo bilateral salpingectomy or bilateral salpingo-oophorectomy.
- Patients may then undergo oophorectomy after initial surgery.
- Patients also undergo a transvaginal ultrasound during screening and blood sample collection throughout the trial.
Eligibility of study
You may be eligible for this study if you meet the following criteria:
- Conditions: Ovarian Carcinoma
-
Age: Between 35 Years - 50 Years
-
Gender: Female
Inclusion criteria:
- Patients who are undergoing 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 and consent. Prior hysterectomy is allowed provided it did not include bilateral salpingectomy. Prior tubal ligation is allowed if one intact 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
- Patients may be premenopausal or menopausal
- 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
- Individuals who are currently pregnant or plan to become pregnant in the future through assisted reproductive technologies and who have received proper counseling are eligible. Individuals who are currently pregnant and plan bilateral salpingectomy at the time of a planned cesarean section are eligible. Patients must understand that they will not be able to become pregnant naturally in the future
Exclusion Criteria:
- Individuals with a history of any prior cancer who have received chemotherapy within the past 30 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 premenopausal individuals if they are not current users of oral contraceptives; an abnormal CA-125 is defined as a level > 40 U/ml for premenopausal individuals who are current users of oral contraceptives. An abnormal CA-125 is defined as a level > 35 U/ml in postmenopausal individuals
