Brief Summary:


People with prostate cancer usually have their cancer imaged with a CT scan and bone scan. They then have their prostate gland removed. Researchers want to test a scan that might predict if prostate cancer will return after this surgery.


To test if a PET/CT scan before the prostate gland is removed can predict if prostate cancer will return. Also, to test if this approach is better or worse than the usual approach for prostate cancer.


Men ages 18 and older with prostate cancer that appears to be contained within the prostate but is at risk of having spread


Participants will be screened with:

  • Medical history
  • Blood tests
  • CT and MRI scans: Participants will lie in a machine. The machine will take pictures of the body.
  • Bone scan

Participants will have a radiotracer injected into a vein. They will have a PET/CT scan of their whole body 60 90 minutes later. During the scan, they will lie on their back and stay still.

Within 60 days after the scan, participants will have surgery. This will remove the prostate gland and lymph nodes around it. Some tissue will be used for genetic testing.

If the PET/CT scan suggests the cancer has spread, participants may need to have another biopsy within 60 days after the scan.

After surgery, participants will have follow-up visits for 5 years. They will have 5 visits the first year and 2 the second. Then they will have visits once a year.

If participants cancer returns, they will have repeat PET/CT scans.

Arm Intervention/treatment
Experimental: 1/18F-DCFPyL PET/CT + radical prostatectomy
18F-DCFPyL PET/CT with radical prostatectomy and lymphadenectomy
Drug: 18F-DCFPyL
18F-labeled agent that is a high affinity small molecule inhibitor of PSMA to detect prostate cancer via PET imaging

Primary Outcome Measures :
  1. progression free survival [ Time Frame: 6 weeks, 3,6,9,12, and 18 months, 2,3, and 4 years ]
    progression-free survival which is improved over that of historical data from a general population

Secondary Outcome Measures :
  1. progression free survival [ Time Frame: 6 weeks, 3,6,9,12, and 18 months, 2,3, and 4 years ]
    progression-free survival of patients with an 18F-DCFPyL PET/CT that is positive for metastases

Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No
  • Patients must have histologically proven prostate adenocarcinoma confirmed by a CLIA certified laboratory.
  • Must have prostate cancer with high risk features defined as:

    • Gleason 8 and higher OR
    • PSA > 20 ng/mL OR
    • Clinical stage T3a (i.e. likely extraprostatic extension on MRI) or T3b
  • Patients must be eligible for and must be planning to undergo radical prostatectomy and lymphadenectomy regardless of findings on 18F-DCFPyL PET/CT
  • Men age greater than or equal to 18 years.
  • ECOG performance status <2
  • Patients must have adequate organ and marrow function as defined below:

    • Hemoglobin greater than or equal to 9 g/dL
    • leukocytes greater than or equal to 3,000/mcL
    • platelets greater than or equal to 100,000/mcL
    • total bilirubin <2 X normal institutional limits
  • AST(SGOT)/ALT(SGPT) less than or equal to 3 X normal institutional limits
  • creatinine <2 X normal institutional limits


eGFR greater than or equal to 50 mL/min/1.73 m2 for patients with creatinine levels above institutional normal.

  • Ability of subject to understand and the willingness to sign a written informed consent document.
  • Willingness and ability to undergo biopsy of radiotracer-avid lesion if feasible.
  • Willingness and ability to undergo multiparametric prostate MRI and 18F-DCFPyL PET/CT


  • Any investigational agents in the past 28 days prior to enrollment.
  • Clinical stage T4 (tumor invades adjacent structures except seminal vesicles).
  • Distant metastatic disease on conventional imaging studies (computed tomography (CT)) of the abdomen and pelvis and bone scan. NaF PET/CT scan cannot substitute for a bone scan. Given lack of specificity of CT for lymph node metastases at lower thresholds, pelvic lymph nodes below 2 cm in the short axis are allowed.
  • Any prior hormone therapy used to treat prostate cancer, except limited androgen receptor antagonist therapy, defined as less than or equal to 3 days of treatment. The medication must be discontinued within 5 half-lives of the compound prior to study entry.
  • Any prior therapy for prostate cancer with surgery, radiation, and/or chemotherapy.
  • Contraindication to MRI or PET:

    • Patients weighing more than weight limit for the scanner tables or unable to fit within the imaging gantry
    • Prior reaction to 18F-DCFPyL
    • Patients with pacemakers, cerebral aneurysm clips, shrapnel injury or implantable electronic device that are not MRI compatible at 3 T
    • Severe claustrophobia unresponsive to oral anxiolytics
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  • Other medical conditions deemed by the principal investigator (or associates) to make the subject unsafe/ineligible for the protocol procedures or for radical prostatectomy.
  • A malignancy within the past 3 years for which prostatectomy is a contraindication.
  • Radiotracer administered within 5 half-lives prior to the date of 18F-DCFPyL PET/CT imaging.
  • PSMA-targeted imaging within 6 months with 18F-DCFPyL tracer prior to the date of 18F-DCFPyL PET/CT imaging. Participants can have PSMA targeted imaging with Gallium.
  • Unable to refrain from fathering a child or donating sperm for 10 days after each 18FDCFPyL injection.
