Psychological impact of providing women with personalised 10-year breast cancer risk estimates

Menée au Royaume-Uni par questionnaire auprès de 2 138 femmes participant au programme de dépistage organisé du cancer du sein, cette étude analyse les effets, sur leur niveau d'anxiété et d'inquiétude, des résultats d'une estimation personnalisée du risque de cancer à 10 ans

Background : The Predicting Risk of Cancer at Screening (PROCAS) study estimated 10-year breast cancer risk for 53,596 women attending NHS Breast Screening Programme. The present study, nested within the PROCAS study, aimed to assess the psychological impact of receiving breast cancer risk estimates, based on: (a) the Tyrer–Cuzick (T-C) algorithm including breast density or (b) T-C including breast density plus single-nucleotide polymorphisms (SNPs), versus (c) comparison women awaiting results. Methods : A sample of 2138 women from the PROCAS study was stratified by testing groups: T-C only, T-C(+SNPs) and comparison women; and by 10-year risk estimates received: 'moderate' (5–7.99%), 'average' (2–4.99%) or 'below average' (<1.99%) risk. Postal questionnaires were returned by 765 (36%) women. Results : Overall state anxiety and cancer worry were low, and similar for women in T-C only and T-C(+SNPs) groups. Women in both T-C only and T-C(+SNPs) groups showed lower-state anxiety but slightly higher cancer worry than comparison women awaiting results. Risk information had no consistent effects on intentions to change behaviour. Most women were satisfied with information provided. There was considerable variation in understanding. Conclusions : No major harms of providing women with 10-year breast cancer risk estimates were detected. Research to establish the feasibility of risk-stratified breast screening is warranted.
