More breast cancer patients prefer BRCA-mutation testing without prior face-to-face genetic counseling

Abstract

Currently, most breast cancer (BC) patients receive face-to-face genetic counseling (DNA-intake) prior to BRCA-mutation testing, with generic information regarding hereditary BC and BRCA-mutation testing. This prospective study evaluated a novel format: replacing the intake consultation with telephone, written and digital information sent home, and face-to-face contact following BRCA-mutation testing (DNA-direct). From August 2011 to February 2012, 161 of 233 eligible BC patients referred to our Human Genetics department chose between DNA-direct (intervention) or DNA-intake (control). Exclusion criteria were psychological problems (n = 33), difficulty with Dutch text (n = 5), known BRCA-family (n = 3), non-BRCA-referral (n = 1). 30 declined genetic counseling or study participation. Participants received questionnaires including satisfaction and psychological distress. 59 % chose DNA-direct (p = 0.03), of whom 90 % were satisfied and would choose DNA-direct again (including 6/8 BRCA-mutation carriers); although 27 % hesitated to recommend DNA-direct to other patients. General distress (GHQ-12, p = 0.001) and heredity-specific distress (IES, p = 0.02) scored lower in DNA-direct than DNA-intake, both at baseline and follow-up 2 weeks after BRCA-result disclosure; all scores remained below clinical relevance. DNA-direct participants reported higher website use (53 vs. 32 %, p = 0.01), more referrer information about personal consequences (41 vs. 20 %, p = 0.004) and lower decisional conflict (median 20 [0-88] vs. 25 [0-50], p = 0.01). Processing time in DNA-direct was reduced by 1 month. Mutation detection rate was 8 % in both groups. All BRCA-mutation carriers fulfilled current testing criteria. In conclusion, more BC patients preferred DNA-direct over intake consultation prior to BRCA-mutation testing, the majority being strongly to moderately satisfied with the procedure followed, without increased distress.
