OBJECTIVE: To estimate the incidence of genetic counseling referral for ovarian cancer patients who are at substantial risk for a BRCA1 or BRCA2 mutation. METHODS: An analysis was performed of new ovarian cancer patients who were seen at a comprehensive cancer center from January 1, 1999, through December 31, 2007. Patients at substantial (more than 20-25%) risk for a BRCA1 or BRCA2 mutation were identified and records reviewed for referral to genetic counseling. Time to referral was estimated using the Kaplan-Meier method. RESULTS: A total of 3,765 epithelial ovarian cancer patients were seen during the 9-year period. On average, 23.8% of patients met substantial-risk criteria for BRCA mutations. In 1999, only 12% of patients at substantial-risk were referred. Referral improved over time with 48% referred in 2007 (P<.001). Newly diagnosed patients were more often referred for genetic counseling than new patients with recurrent disease or those seen as second opinions. African-American women meeting substantial-risk criteria were less likely to be referred than were white or Hispanic women (P=.009). CONCLUSION: Although dictated family history was accurate, interpretation of risk for BRCA1 or BRCA2 mutations and subsequent referral to genetic counseling was poor. Although there was significant improvement over time, 50% of substantial-risk patients still were missed. Systematic efforts to identify those ovarian cancer patients at substantial risk for a BRCA1 or BRCA2 are necessary.
