The role of prophylactic oophorectomy in cancer prevention.
Prophylactic oophorectomy is presently the only effective method of ovarian cancer prevention. This study reviews current data on how prophylactic oophorectomy (PO) should be used in different risk groups. It is estimated that 7% of ovarian cancer patients have positive family history, of which 3-9% may end up having hereditary cancer syndromes. Women in direct genetic lineage of family cancer syndromes may have up to 50% lifetime risk of ovarian cancer. Because of such a high risk, PO is indicated for women with familial cancer syndromes after childbearing or the age of 35-40 at the latest. Most women with positive family history of ovarian cancer do not have one of the recognized hereditary cancer syndromes. However, women with one or two affected relatives do have an increased lifetime risk of ovarian cancer from a baseline of 1.6 to 5-7%. This risk is not high enough to warrant PO recommendation for a large number of women. After being properly informed and the patient still desires surgical prevention (i.e., cancer phobia), PO then becomes an indicated procedure. In women without family history of ovarian cancer, the role of PO remains controversial. The decision of PO as a concurrent procedure to other indicated gynecologic surgeries should depend on the individual patient and her ability to comply with lifelong estrogen replacement therapy.
