Abstract P3-10-03: Receipt of breast cancer risk assessment and personalized prevention information among women diagnosed with a benign breast lesion (BBL) in a one stop breast unit: A prospective assessment

Abstract

Abstract Background: Women's awareness about their personal breast cancer (BC) risk in the general population is generally low. Mass screening and mass prevention interventions have as yet been moderately efficient in breast oncology. "Personalized prevention" including risk communication, personalized screening and primary prevention recommendations is a promising. A personal history of BBL slightly increases subsequent BC risk. Objectives: the main objective was to evaluate the acceptability of a mathematical tool- based breast cancer risk assessment and subsequent proposal of a personalized BC prevention program in a BBL population. Secondary objectives were to evaluate information receipt, awareness, satisfaction, and anxiety. Methods: Women were eligible for the study if aged 40-74, were recently diagnosed with a benign breast lesion at the one stop breast Unit of the center, had no personal history of cancer or atypical lesions and were not BRCA carriers. Women were proposed a personalized risk assessment using a mathematical tool (BCSC score adapted to the French population-Ragusa et al) together with personalized information on risk, BC screening and prevention, release of a personalized program and evaluation of their receipt. The main end point was the proportion of women willing to have a risk assessment and personalized counseling. A cut-off point of 70% was considered critical to consider acceptability. Secondary end points were perceived BC risk, satisfaction, anxiety and distress levels at day 2 using standardized questionnaires, as well as adherence with the proposed programs. Results: Of 150 women proposed BC risk assessment and personalized prevention information between 02/2014 and 03/2015, 129 (86%) accepted. Median age: 53.6 years. 33% had a low BC risk (< 1.1% at 5 yrs [mean risk of 50 yrs-old women in France]), 53% a moderate risk (1.1-1.66% at 5 yrs), while 14% were high risk (> 1.66% at 5 yrs). 87% had never had any previous information on BC risk. 3 pts required a genetic assessment. Participants were globally very satisfied with physicians' and nurses' interpersonal skills, availability and provision of information (mean score > 4; range 2-5). The mean scores of clarity of the BC risk information (4.14±1;range 2-5) and screening program information (4.21±0.93; range 2-5) were high. The mean score of perceived risk level was estimated to 33.5% (SD=21.9). Mean scores of state anxiety (36.7±12.2; range 20-71), trait anxiety (39.5±8.9; range 23-59), depressive symptoms (3.4±3.3; range 0-12) and psychological distress indicated low levels of all. Higher level of state-anxiety was associated with lower scores of satisfaction with doctors and nurses human qualities (r = 0.26, p<.05) and with lower scores of clarity of information about screening program (r = 0.25, p<.05). Conclusion: The receipt of breast cancer risk assessment and personalized prevention information among women diagnosed with BBL was high (86%). Information need is high given the low level of real risk awareness. Such population may benefit from personalized prevention. Anxiety and distress scores were low and satisfaction rates high.
