New study aims to cut unnecessary prostate biopsies with MRI
NCT ID NCT04993508
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new way to diagnose prostate cancer using PSA tests, digital rectal exams, and MRI scans. Men aged 50-75 with elevated PSA or suspicious exams will get an MRI first. Only those with suspicious MRI results will have a biopsy, and they will be randomly assigned to either MRI-targeted biopsy alone or combined with standard systematic biopsy. The goal is to see if targeted biopsy alone can find serious cancers while avoiding unnecessary detection of low-risk cancers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could make prostate cancer diagnosis more accurate, reducing unnecessary biopsies and overtreatment.
- What could go wrong
- This is an early-stage study not yet recruiting, and results may not apply to all men or settings. MRI-targeted biopsy might miss some cancers.
