A Study to Compare Two Surgical Procedures in Individuals With BRCA1 Mutations to Assess Reduced Risk of Ovarian Cancer
NCT04251052
Recruiting
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... Read More
