Risk-based cancer prevention is a major future strategy. “Interception” is a French pilot, mixed community-hospital and digital-physical programme based on 4 pillars: 1. community-based identification of people at high risk of cancer; 2. a One-Stop Shop (OSS) including individual visits and group workshops to inform and empower patients and design their shared personalised prevention plan; 3. Implementation of this plan in community practice; 4. Fast cancer care pathway if required. We assessed the pathway dedicated to women at increased non-genetic risk of BC (CANRISK-based 5-year risk of invasive BC >2.5%).
We analysed data of women at high risk of BC non linked to a germline variant seen between 02/2021 and 12/2022. Nutritional habits and physical activity assessments used the WCRF score. Perception of knowledge on risk, prevention and screening, and self-evaluated lifetime probability and compared probability of BC, were assessed before and 8 days after OSS (analogue visual scales); comparisons used paired Wilcoxon tests.
141 women at high non-genetic BC risk entered the programme. Mean age was 40.5 years [32.2-49], 81% had tertiary education. Recommended BC screening scheme was modified in 64% (increased mammography frequency: 36 (50%), addition of yearly MRI: 36 (50%)). Identified BC prevention targets were: insufficient physical activity (83%), overweight or obesity (36%), alcohol consumption (57% incl. 5% with >1 alcohol drink/day), current smoking (21%). 97% had at least 1 prevention target. The mean perceived knowledge on BC risk improved (58.0% before
A programme dedicated to women at high BC risk has the ability to improve screening measures in conformity with current guidelines (51%), identify relevant prevention targets (97%), improve knowledge on one’s individual situation by 50%, and improve perceived cancer risk’s accuracy.
