Comparing MRI-Ultrasound Fusion and Cognitive-guided Biopsy for the Detection of csPCa: the PROFUSION Trial

Not Applicable

Recruiting

• Conditions: Prostate Cancer

• Registration Number: NCT06303622
• Lead Sponsor: Chinese University of Hong Kong

Brief Summary

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.

Detailed 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.
