18F-DCFPyL PET-CT Scan and Prostate Cancer

This is a single arm Phase II clinical trial in Veterans with prostate cancer, no prior local therapy, who are at risk of having metastatic disease (PSA greater than 10, or Gleason Score greater than or equal to 4+3, or clinical stage greater than or equal to T2c). Veterans who are planned to undergo or have recently undergone conventional, routine care initial staging scans for prostate cancer (99mTc-MDP or NaF PET bone scan and diagnostic CT or MRI of pelvis) will also receive a 18F-DCFPyL PET-CT scan. The primary endpoint is the percent of Veterans with prostate cancer in which the 18F-DCFPyL PET-CT scan identifies evidence of M1 disease at initial staging.
