Double scan strategy could sharpen prostate cancer staging
NCT ID NCT07455097
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether combining PSMA-PET/CT and MRI scans can more accurately determine the extent of prostate cancer in men with intermediate- or high-risk disease. Researchers will compare scan results with tissue samples from 600 men who had their prostate removed. The goal is to improve staging and guide personalized treatment decisions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PSMA-11 (diagnostic tracer)
- What this could lead to
- If successful, this could lead to more accurate staging of prostate cancer, helping doctors choose better treatments and avoid unnecessary surgery.
- What could go wrong
- This is a retrospective analysis, not a controlled trial, so results may not apply to all patients. The imaging techniques are already in use, so the benefit may be modest.

Who is studied
Men at intermediate risk (PSA \> 10 ng/ml to 20 ng/ml or Gleason score 7 or cT category 2b) or high risk (PSA \> 20 ng/ml or Gleason score ≥ 8 or cT category 2c) who underwent PSMA-PET/CT and mpMRI and subsequentially RP will be analyzed in three different subgroups, assigned to the modalities they underwent in staging in addition to MRI: i) PSMA-PET/CT using 18-F-DCFPyL (subgroup/arm A), ii) PSMA-PET/CT using Gallium-68 (subgroup/arm B) and PSMA-PET/CT using Fluorine-18 (subgroup/arm C). Validation of the accuracy of intraprostatic lesion detection, local staging and of LN-Staging by MRI or PSMA-PET/CT with different tracers is confirmed after radical prostatectomy.
