Individualized survival curves improve satisfaction with cancer risk management decisions in women with BRCA1/2 mutations

Abstract

Purpose: Women with BRCA1/2 mutations are faced with complex decisions about breast and ovarian cancer risk management. This study was conducted to determine the effect of a tailored decision support system (DSS) that provides individualized survival and cancer incidence curves specific to expected outcomes of alternative management strategies. Patients and Methods: This was a double-blind, randomized controlled trial of 32 women with BRCA1/2 mutations. Primary outcome measures were decision satisfaction, cancer anxiety, perceptions of cancer risk given alternative management strategies, and management decisions. Results: Twenty-seven women completed a 6-week follow-up. Women in the intervention arm (n = 13) reported significantly higher decision satisfaction at follow-up than women in the control arm (n = 14; adjusted mean difference, 9.7; P
