Abstract

Purpose:Population screening of three common BRCA1/BRCA2 mutations in Ashkenazi Jews (AJ) apparently fulfills screening criteria. We compared streamlined BRCA screening via self-referral with proactive recruitment in medical settings.Methods:Unaffected AJ, age ≥25 years without known familial mutations, were either self-referred or recruiter-enrolled. Before testing, participants received written information and self-reported family history (FH). After testing, both non-carriers with significant FH and carriers received in-person genetic counseling. Psychosocial questionnaires were self-Administered 1 week and 6 months after enrollment.Results:Of 1,771 participants, 58% were recruiter-enrolled and 42% were self-referred. Screening uptake was 67%. Recruited enrollees were older (mean age 54 vs. 48, P < 0.001) and had less suggestive FH (23 vs. 33%, P < 0.001). Of 32 (1.8%) carriers identified, 40% had no significant FH. Post-Test counseling compliance was 100% for carriers and 89% for non-carrier women with FH. All groups expressed high satisfaction (>90%). At 6 months, carriers had significantly increased distress and anxiety, greater knowledge, and similar satisfaction; 90% of participants would recommend general AJ BRCA screening.Conclusion:Streamlined BRCA screening results in high uptake, very high satisfaction, and no excess psychosocial harm. Proactive recruitment captured older women less selected for FH. Further research is necessary to target younger women and assess other populations.Genet Med advance online publication 08 December 2016.
