A sharper eye for cancer: new PET tracer targets hidden tumors
NCT ID NCT06690970
First seen Sep 08, 2026 · Last updated Sep 09, 2026 · Updated 1 time
Summary
Researchers are testing whether a radioactive tracer called 68Ga/18F-PSMA/PSFA can improve PET/CT scans for finding tumors in people with PSMA-related cancers, including prostate and liver cancer. The study will enroll 500 adults with suspected, newly diagnosed, or previously treated malignant tumors. Each participant receives one injection of the tracer and then undergoes imaging. The team will measure how brightly the tracer lights up each lesion and calculate the scan's sensitivity, specificity, and accuracy in detecting primary tumors and metastases.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 68Ga/18F-PSMA/PSFA, a radioactive tracer injected intravenously before PET/CT imaging
- What this could lead to
- If it works, this imaging approach could help doctors detect cancers and their spread more accurately, guiding treatment decisions.
- What could go wrong
- The trial is early and focuses on imaging accuracy, not patient outcomes. The tracer may not clearly distinguish all tumor types, and results may vary across different cancers.
