Summary

This is a randomized controlled trial to evaluate the detection of clinically significant prostate cancer (csPCa) by MRI-targeted approach (MRI-arm) versus 24-core transperineal (TP) systematic biopsy (TP-arm). Clinically significant prostate cancer (csPCa) is defined as ISUP (International Society of Urogenital Pathology) Grade group ≥2 prostate cancer. Patients with elevated PSA 4-20 ng/mL with or without abnormal digital rectal examination (DRE) will be randomized in a 1:1 manner to MRI-arm or TP-arm. In the MRI-arm, multiparametric MRI prostate will be performed for each subject. MRI prostate is considered abnormal if PI-RADS (Prostate Imaging-Reporting and Data System, version 2.1) score is 3, 4 or 5. For subjects in MRI-arm with abnormal MRI, MRI-targeted biopsy will be performed, followed by 12-core systematic transperineal biopsy (sparing MRI-target). For subjects in MRI-arm with normal MRI, no biopsy is performed. For subjects in TP-arm, 24-core systematic transperineal biopsy will be performed without MRI guidance. The study flowchart is provided in Figure 1. The detection rates of csPCa will be compared between MRI-targeted biopsy plus 12-core systematic biopsy (in MRI-arm) versus TP-arm. The study hypothesis is MRI-guided prostate biopsy with 12-core systematic biopsy is superior to 24-core transperineal systematic biopsy in detection of csPCa.

Conditions

Interventions

DIAGNOSTIC_TEST

MRI and MRI-guided prostate biopsy

Multiparametric MRI prostates in the MRI arm will be performed using 1.5 or 3.0 Tesla scanner with a pelvic phased array coil and contrast injection. T2-weighted, diffusion weighted and dynamic contrast enhanced scans will be included and the reporting of MRI finding will be done according to PI-RADS (Prostate Imaging-Reporting and Data Systems) v2.1 recommendations. MRI-guided targeted biopsy will be performed by Urologists experienced in MRI-guided biopsy for men with PI-RADS score 3-5.

DIAGNOSTIC_TEST

TP-arm Systematic biopsy

Transperineal 24-core biopsy using a free-hand technique under local anaesthesia will be performed under transrectal ultrasound guidance for men in this arm
