WISDOM randomized trial comparing risk-based versus annual breast cancer screening: study cohort characteristics and design

Le résumé fourni par la source

The Women Informed to Screen Depending on Measures of risk (WISDOM) Study (NCT02620852) is pragmatic randomized controlled trial evaluating risk assessment to inform the age to start, frequency and modality of breast cancer screening and risk reduction. The WISDOM Study uses a preference-tolerant design, enabling women who decline randomization to self-select their screening arm. The risk-based arm included comprehensive breast cancer risk assessment using the Breast Cancer Surveillance Consortium (BCSC) model and genetics. From August 2016 - February 2023, WISDOM enrolled a large, diverse, nationwide cohort of 46,403 participants - 77% non-Hispanic (NH) White, 9% Hispanic, 6% (NH) Black, and 5% (NH) Asian; demographic diversity increased over time. Mean age at baseline was 54 years. 28,372 (61%) were randomized, while 89% of those who self-selected their screening arm chose risk-based screening. The preference-tolerant design captured real-world screening preferences while maintaining scientific rigor and demonstrated strong preference for risk-based screening.
