Can a genetic test predict hidden cancer spread? new study uses advanced scans to find out
NCT ID NCT03495427
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at 60 men with prostate cancer who had a high-risk genetic test (Decipher score >0.45). They will get a special PSMA-PET scan two years after their initial treatment to see if the cancer has spread. The goal is to learn how well the genetic test predicts early metastasis, not to provide a new treatment.
