Not Applicable

Recruiting

• Conditions: Ovarian Carcinoma

• Registration Number: NCT04251052
• Lead Sponsor: NRG Oncology

Brief Summary

This study 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.

Detailed Description

PRIMARY OBJECTIVE:

I. To compare the non-inferiority of bilateral salpingectomy (BLS) with delayed oophorectomy to bilateral salpingo-oophorectomy (BSO) to reduce the risk of ovarian cancer among individuals with deleterious BRCA1 germline mutations.

SECONDARY OBJECTIVES:

I. To prospectively assess estrogen deprivation symptoms in pre-menopausal BLS patients as measured by the Functional Assessment of Cancer Therapy - Endocrine Symptom (FACT-ES) subscale compared to pre-menopausal patients in the BSO arm.

II. To determine if health-related quality of life (QOL) (FACT) is negatively impacted by menopausal symptoms (menopausal symptom checklist-Menopausal Symptom Checklist \[MSCL\]) and sexual dysfunction (Female Sexual Function Index \[FSFI\]) in pre-menopausal patients who have undergone BLS, in comparison to normative data (MSCL/FACT-ES) and data from pre-menopausal BSO patients.

III. To determine if health-related QOL (FACT) is negatively impacted by cancer distress (Impact of Event Scale \[IES\]) in individuals who have undergone BLS, in comparison to BSO patients.

IV. To assess medical decision making, as measured by the Shared Decision Making Questionnaire (SDM-Q-9) and Decision Regret Scale (DRS), and determine factors associated with the risk of reducing surgical treatment choice.

V. To assess adverse events, graded using Common Terminology Criteria for Adverse Events (CTCAE) version (v)5.0.

EXPLORATORY OBJECTIVES:

I. Sexual dysfunction, as measured by selected Patient-Reported Outcomes Measurement Information System (PROMIS) screener and external sexual function items (pre-menopausal patients).

II. To estimate the cost-effectiveness of BLS compared to BSO for ovarian cancer risk reduction.

III. To assess medical decision making, as measured by the Risk-Reducing Medical Decision Making (RR-MDM) survey, a targeted set of questions on risk reducing surgical treatment choice.

TRANSLATIONAL RESEARCH OBJECTIVE:

I. To bank tissue and blood biospecimens for future research.

OUTLINE: This is an observational study. Patients choose between 1 of 2 groups.

GROUP I: Patients undergo bilateral salpingectomy. Patients may then undergo oophorectomy after initial surgery.

GROUP II: Patients undergo bilateral salpingo-oophorectomy.

Patients in both groups also undergo a pelvic or transvaginal ultrasound during screening and blood sample collection throughout the trial.

After completion of study, patients are followed up at 10-60 days, 6, 12, and 24 months, and then annually for up to 20 years.

Recruitment & Eligibility

• Status: RECRUITING
• Sex: Female
• Target Recruitment: 2262

Inclusion Criteria

• 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
• Patients may be premenopausal or menopausal
• Pelvic ultrasound (transvaginal imaging preferred, but transabdominal imaging is acceptable) 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 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, CA-125) suspicious for occult or gross pelvic malignancy within the past 180 days

  • An abnormal pelvic ultrasound is defined as morphologic or structural variations suspicious for ovarian malignancy. Complex cystic lesions felt to represent a benign lesion are not exclusionary. Simple cysts of any size are not exclusionary
  • An abnormal CA-125 is defined as a level > 50U/ml in premenopausal individuals if they are not current users of oral contraceptives; an abnormal CA-125 is defined as a level > 40U/ml for premenopausal individuals who are current users of oral contraceptives (Skates 2011). An abnormal CA-125 is defined as a level > 35 U/ml in postmenopausal individuals

Primary Outcome Measures

Name	Time	Method
Time to development of incident high-grade serous carcinomas (HGSC), specifically ovarian, primary peritoneal, or fallopian tube cancers	Up to 20 years	Will be assessed using a stratified log rank test, stratifying for age. The effects of other covariates, such as familial history of gynecologic cancer, time to crossover for bilateral salpingectomy (BLS) patients, and age at study entry, will be adjusted for in Cox proportional hazard models. Patients who crossover will be analyzed according to the initial surgery received at study enrollment as this will reflect actual practice.

Secondary Outcome Measures

Name	Time	Method
Health-related quality of life (QOL)	Up to 24 months post-surgery	Will be measured by the Functional Assessment of Cancer Therapy - Endocrine Symptom (FACT-ES). The FACT total score (calculated from the physical, functional, social and emotional well-being subscales) and ES subscale will be assessed. Scores range from 0 to 76. Higher scores indicate better QOL for the FACT-ES and better functioning for the Female Sexual Function Index (FSFI) total score.
Cancer distress	Up to 24 months post-surgery	Will be measured by the Impact of Events Scale (IES). The total score can range from 0 to 88, with higher scores indicating a greater impact of the event.
Medical decision making	Up to 24 months post-surgery	Will be measured by the Shared Decision Making Questionnaire (SDM-Q-9) and, Decisional Regret Scale. The SDM-Q-9 total score and Decisional Regret Scale total score at each time point of collection will be compared between arms using a t-test with a significance level of 0.05. A linear model will be used to assess the association of the SDM-Q-9 total score with treatment arm and patient characteristics such as age and race. A similar model will be used to assess the association of the Decisional Regret Scale total score with treatment arm and patient characteristics such as age, race, crossover from BLS arm, and hysterectomy status. minimum score of 0 and a maximum score of 45. A higher score indicates a greater level of perceived shared decision-making in a consultation.
Incidence of adverse events	Up to 20 years	Will be graded according to National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. Counts and frequencies will be provided for the worst grade adverse event (AE) experienced by the patient by treatment arm. The distribution of AE grade in the BLS arm will be compared to the bilateral salpingo-oophorectomy arm using a chi-square test, or Fisher's exact test if cell frequencies are \< 5, at the one-sided 0.05 significance level.
Estrogen deprivation symptoms (pre-menopaused patients only)	Up to 24 months post-surgery	Will be measured by the FACT-ES. The FACT total score (calculated from the physical, functional, social and emotional well-being subscales) and ES subscale will be assessed. Scores range from 0 to 76. Higher scores indicate better QOL for the FACT-ES and better functioning for the FSFI total score. Models will also include hormonal therapy as a covariate.
Sexual dysfunction (pre-menopausal patients only)	Up to 24 months post-surgery	Will be measured by the FSFI. Scores range from 0 to 36. Higher scores indicate better functioning for the FSFI total score.
Menopausal symptoms (pre-menopausal patients only)	Up to 24 months post-surgery	Will be measured by the Menopausal Symptom Checklist (MSCL). Models will also include hormonal therapy as a covariate. The MSCL total score and individual items will be compared between groups using the t-test and Wilcoxon test, respectively. The change from baseline in total score will be compared between groups at each follow-up time point. The change form baseline in the 3 items not included in the subscale scores will be compared between groups using the Wilcoxon test at each follow-up time point.
