Implementing Polygenic Risk Scores for Breast Cancer Prevention: a Feasibility Study

RecruitingNA

Sponsor: Catholic University of the Sacred Heart

Conditions: Breast Cancer

Interventions: Clinical pathway for breast cancer prevention based on PRS-integrated CanRisk assessment

Countries: Italy

This single-arm interventional feasibility study will evaluate whether integrating polygenic risk scores (PRS) into the CanRisk model can improve breast cancer risk prediction and personalized prevention in women at risk of breast cancer. The study will assess the organizational feasibility, patient acceptance, emotional impact and satisfaction of an integrated pathway combining PRS testing with standard genetic counseling and other risk factors at Fondazione Policlinico Universitario Agostino Gemelli IRCCS.
