Overview
This study is an international multicentre RCT to compare the linically significant prostate cancer (csPCa) detection of cognitive-guided and MRI-USG guided biopsies in men with suspicious MRI lesion.
Description
This study is an international multicentre RCT to compare the csPCa detection of cognitive-guided and MRI-USG guided biopsies in men with suspicious MRI lesion. This is a phase III randomised controlled trial to evaluate the detection of clinically significant prostate cancer (csPCa) by MRI-USG fusion approach (MRUS arm) versus Cognitive-guided approach (COG arm). The study hypothesis is that MRUS arm is superior to COG arm in detecting csPCa. The result of this RCT would impact how MRI-guided prostate biopsies should be done in the future. If the MRI-USG fusion approach is superior to cognitive-guidance in csPCa detection, it should be the standard of practice in the future, and dedicated MRI-USG fusion equipment should be available in centres performing prostate biopsies.
Eligibility
Inclusion Criteria:
- Men ≥18 years of age
- Clinical suspicion of prostate cancer and indicated for prostate biopsy
- Serum Prostate-specific antigen (PSA) < 20 ng/mL
- Digital rectal examination ≤ cT2 (organ-confined cancer)
- Able to provide written informed consent
- MRI prostate (contrast or plain) showing 1-3 suspicious lesion(s) with PI-RADS score 3-5
Exclusion Criteria:
- Prior prostate biopsy in the 2 years before screening visit
- Prior diagnosis of prostate cancer
- Contraindicated to prostate biopsy: active urinary tract infection, failed insertion of transrectal ultrasound probe into rectum (abdominal perineal resection, anal stenosis), uncorrectable coagulopathy, antiplatelet or anticoagulant which cannot be stopped (continue low-dose aspirin before and after biopsy is permitted)
- Patient refusal for biopsy
