In this open randomized controlled trial, we seek to study whether prostate cancer screening using multiparametric prostate magnetic resonance imaging (mpMRI) improves the detection rate of clinically-significant prostate cancer (defined as Gleason score ≥7 on prostate biopsy) compared with prostate cancer screening using prostate-specific antigen (PSA).
The current paradigm of prostate cancer screening relies upon an initial PSA blood test, with subsequent investigations driven by the serum PSA level. This model has proven highly controversial due to the inability of PSA level to discern between indolent and aggressive forms of prostate cancer. As a result, numerous government-sponsored bodies have recommended against PSA screening. Evidence suggests that prostate cancer screening has led to an increased proportion of men being diagnosed with potentially curable prostate cancer. However, due to the inability of the PSA level to accurately distinguish patients with indolent and lethal forms of prostate cancer, it has led to a significant rate of over-diagnosis of indolent disease. Magnetic resonance imaging has been gaining an increasingly large role in the management of patients with clinically-localized prostate cancer including diagnosis in patients with abnormal PSA levels, monitoring of patients on active surveillance and staging prior to definitive interventions. MRI-based prostate cancer risk assessment has been shown to better distinguish between clinically-significant and insignificant tumors than PSA test. Therefore, a randomized controlled trial of MRI-based prostate cancer screening and PSA-based prostate cancer screening is warranted.

Experimental: Multi-parametric MRI
Patients from the general population without history of previous prostate biopsy will be allocated to receive mpMRI in order to evaluate for risk of prostate cancer.
Device: Multi-parametric MRI
Non contrast magnetic resonance imaging using T1/T2 weighting, DWI and ADC will be performed. MRI images will be reviewed by a single uro-radiologist and assessed using the PiRADs standards.
Active Comparator: PSA Only
Patients from the general population without history of previous prostate biopsy will be allocated to receive serum PSA testing in order to evaluate for risk of prostate cancer.
Patients with a serum PSA level less than 4.0 ng/mL will be managed expectantly with results provided to their primary care physician.
Other: PSA testing
Serum prostate specific antigen (PSA) testing will be performed using a standardized laboratory assay.
- Clinically-significant prostate cancer [ Time Frame: Within 3 years of randomization ]Gleason score greater than or equal to 7 on TRUS prostate biopsy
- Clinically-insignificant prostate cancer [ Time Frame: Within 3 years of randomizations ]Gleason score equal to 6 on TRUS prostate biopsy
