A Study to Compare Two Surgical Procedures in Women with BRCA1 Mutations to Assess Reduced Risk of Ovarian Cancer (SOROCk)

About the study

SOROCk [NRG-CC008] is a clinical trial studying if removal of just the can reduce the risk of ovarian cancer nearly as much as removing both the ovaries and among women with an inherited  mutation. The main benefit of removing only the and not the ovaries is to prevent surgically-induced menopause. The study will also examine various patient-reported quality of life outcomes. Researchers believe that most ovarian cancers first begin in the , suggesting that removing the only may prevent the development of ovarian cancer. This concept has never been formally testing in a clinical trial.

What the Study Entails

Here are the steps to participate in the SOROCk Study:

  • Plan for ovarian cancer surgical risk reduction with either:
    • Standard of care surgery to remove both ovaries and
    • Investigational surgery to remove only the with a plan to remove the ovaries at a later time
    • Completing personal and family history questionnaires
    • Have recently had a normal pelvic and a normal CA125 blood test
    • Give consent: This step includes:
    • Reading and signing the consent form to enroll
  • Genetic testing
    • All participants must have an inherited mutation in
  • Get test results
    • Give a copy of your genetic test results from your surgeon.
  • Follow up
    • Follow-up visits will occur after surgery and then once per year for approximately 6 to 16 years. These visits can be done with your surgeon or a local health care provider
    • All participants will be asked to complete an annual questionnaire for up to 20 years after the study. These can be completed electronically on an iphone or similar device.
