bpMRI and Risk Based Shared Clinical Decision Making in Prostate Cancer Diagnosis

The shortcoming of the pre-biopsy prostate MRI approach is the recommendation to biopsy all men post-MRI even if there is no lesion seen in MRI, ie. risk of PCa is very low. Therefore, the primary objective of this trial is to compare if there is a difference between significant cancer detection rate in men undergoing prostate biopsies after MRI scan compared to men undergoing post-MRI prostate biopsies only after a shared decision-making based on prostate cancer risk estimation. The trial will enrol 600 patients. The primary outcome measure is the the proportion of men with CSPCa (Gleason 4+3 prostate cancer or higher) between the control and intervention arms at baseline. Eligible men are randomised 1:1 in two groups. In control arm in all men prostate biopsies are performed after MRI whereas in intervention arm prostate biopsies are performed only after a shared decision-making between urologist and the patient and the discussion is based on risk estimation.
