Introduction/Background It has been estimated that 19,880 new cases of ovarian cancer had been diagnosed in 2022. Most epithelial ovarian cancer are sporadic, while, in 15–25% of cases, there is evidence of a familial or inherited component. About 20–25% of high-grade serous carcinoma cases are caused by germline mutations in the BRCA1 and BRCA2 ge...
