OBJECTIVE:The objectives of this study are to determine (i) what daughters, ages 18-24 years, of BRCA1/2 mutation carriers understand about their 50% chance of carrying a BRCA1/2 mutation and about risk reduction or management options for mutation carriers, (ii) the extent and nature of daughters' cancer-related distress, and (iii) the effects of knowing mother's mutation status on daughters' future plans.
METHODS:A total of 40 daughters, currently aged 18-24 years, of mothers who tested positive for a mutation in BRCA1/2 were invited by mail to participate (with contact information supplied by their mothers). Daughters participated in a qualitative telephone interview about the impact of learning their mother's mutation status on their understanding of their own cancer risks and their cancer-related distress, and their knowledge of screening strategies, risk-reducing surgery, current health status, and future plans. Participants also completed study-specific demographic and family history questionnaires, the Brief Symptom Inventory-18, Impact of Event Scale (with hereditary predisposition to breast/ovarian cancer as the event), and the Breast Cancer Genetic Counseling Knowledge Questionnaire.
RESULTS:Daughters' genetic knowledge is suboptimal; gaps and misconceptions were common. Over 1/3 of the daughters reported high cancer-related distress, despite normal levels of general distress. Disclosed genetic information raised future concerns, especially regarding childbearing.
CONCLUSION:Targeted professional attention to this high-risk cohort of young women is critical to inform the next generation of daughters of BRCA1/2 mutation carriers and encourage recommended screening by age 25 years. Improved uptake of screening and risk reduction options could improve survival, and psychoeducation could reduce cancer-related distress. Copyright © 2013 John Wiley & Sons, Ltd.
