Risk-stratified Approach to Implementing Population-based Prostate Cancer Screening in Five Pilot Sites in the...

Prostate cancer (PCa) is a major public health concern for men globally and the most commonly diagnosed cancer among men in the European Union (EU). Despite large trials suggesting benefits from early detection of PCa, risks of overdiagnosis and overtreatment are evident. In 2022, the EU Commission proposed introducing prostate-specific antigen (PSA) testing for men in an organised setting, in combination with magnetic resonance imaging (MRI) scanning as a follow-up test to minimise these risks. PRostate cancer Awareness and Initiative for Screening Europe (PRAISE-U) is a pilot study evaluating the implementation of a risk-stratified population-based approach to PCa screening in Ireland, Lithuania, Poland, and two areas in Spain (Galicia and Manresa) for feasibility, efficacy, and cost effectiveness. As per the protocol designed for the pilots, men aged 50-69 yr residing within the catchment area of the study sites will be invited to participate. Those consenting to participate will undergo PSA testing, and men with PSA >3 ng/ml will undergo risk stratification before MRI and, if necessary, after MRI before undergoing biopsy. A collaborative user board comprising health care professionals, patients, and decision-makers will be formed to provide stakeholder input throughout the study. PRAISE-U will be evaluated on three major pillars: analysis of clinical and programme outcomes, psychosocial impact, and cost effectiveness. A set of key performance indicators (KPIs) has been developed to be piloted in the PRAISE-U pilot sites. The KPIs will serve to assess the performance and outcomes of risk-stratified PCa screening at each site. A REDCap database will be used to collect and manage pseudoanonymised data from the pilot sites. Ethics approval was obtained from each pilot site. The PRAISE-U pilot implementation is expected to commence in the 3rd quarter of 2024 for 12 mo and provide valuable data on the implementation outcomes of a risk-stratified screening approach across Europe. The findings is expected to inform the development of an optimised screening strategy with an acceptable benefit to harm ratio.
