PSMA-PET Imaging for Detecting Early Metastatic Prostate Cancer in Men w/ High Decipher Test Scores

This trial is using a specialized type of imaging scan (called PSMA-PET) to detect whether prostate cancer has spread to other parts of the body in men who had surgery or radiation and whose tumors were identified as high risk through a genetic test called Decipher. **You may be eligible if...** - You previously took part in the VANDAAM study (MCC#18523) - Your Decipher genetic test score was high risk (above 0.45) - You were treated with surgery (prostate removal) or radiation therapy, with at least 2 years of follow-up since then - You are 18 years of age or older - Your general health is good (ECOG performance status 0 or 1) **You may NOT be eligible if...** - You did not participate in the prior VANDAAM study - Your Decipher score did not meet the high-risk threshold - Your genetic test results from that study were not successfully completed Talk to your doctor to see if this trial is right for you.
