Brief Summary:
This study aims to institute a province-wide registry leveraging the availability of a new Positron Emission Tomography tracer, [18F]-DCFPyL and PET expertise across Ontario centers to improve our ability to characterize patterns of recurrence and personalize therapies in men with recurrent prostate cancer after primary treatment.

Condition or disease Intervention/treatment Phase
Recurrent Prostate Cancer Diagnostic Test: [18F]-DCFPyL PET/ CT scan (PSMA PET) Not Applicable

Detailed Description:
This registry study will provide Ontario centres access to a new Positron Emission Tomography (PET) tracer, [18F]-DCFPyL, to improve our ability to identify areas of prostate cancer recurrence in men who have undergone surgical removal of their prostate gland (radical prostatectomy) or radiation of their prostate (external beam radiation, brachytherapy or a combination of both) and there is a suspicion of recurrence of the cancer. Men with suspected persistent or recurrent disease can be identified on the basis of a rising Prostate Specific Antigen (PSA) blood test, or the presence of node positive disease at the time of their surgery, or a PSA blood test continues to be detectable within 3 months after their surgery. It is the aim of this study to determine if [18F]-DCFPyL PET/CT can potentially identify areas of prostate cancer recurrence not seen with usual imaging (bone scan/CT scans) and impact the management of the disease. A report of the results of the [18F]-DCFPyL PET/CT will be provided to the participating physicians to determine a treatment plan. As part of the patient eligibility for [18F]-DCFPyL PET/CT participating physicians will complete a questionnaire after the [18F]-DCFPyL PET/CT information is provided to report how the results impact patient management. Actual interventions following completion of the [18F]-DCFPyL PET/CT will be tracked by linkage to provincial registries. Six centres across Ontario will participate in the registry study which is expected to take 4 years to complete with an additional one year of follow-up to capture patient outcomes.

Primary Outcome Measures :
  1. Frequency of disease detection on PSMA PET [ Time Frame: 5 years ]
    The number of men with detectable lesions on PSMA PET who have suspected recurrent or persistent disease post radical prostatectomy with or without adjuvant or salvage pelvic radiotherapy or hormone therapy as well as men treated with primary radiotherapy will be measured


Secondary Outcome Measures :
  1. Proportion of men with lesions detectable on PSMA PET imaging but not conventional imaging (CT or bone scan) [ Time Frame: 5 years ]
    Number of lesions detected on PSMA PET compared to conventional imaging

  2. Proportion of men with oligometastatic recurrence (four or fewer sites including the prostate bed if positive) confirmed on PSMA PET/CT [ Time Frame: 5 years ]
    Number of men with four or fewer sites of disease detected on PSMA PET

  3. Proportion of men with extensive recurrence (more than four sites including the prostate bed if positive) confirmed on PSMA PET/CT [ Time Frame: 5 years ]
    Number of men with more than four sites of disease detected on PSMA PET

  4. To determine rates of concordance in lesion detection between conventional imaging (CT/bone scan) and PSMA PET/CT [ Time Frame: 5 years ]
    Number of lesions detected on both conventional imaging and PSMA PET

  5. Proportion of men who have a change in usual management after PSMA PET [ Time Frame: 5 years ]
    Number of men who have their management plan changed because of PSMA PET results

  6. Proportion of men with detectable disease on PSMA PET/CT as a function of PSA parameters (absolute value, PSA velocity, PSA doubling time) [ Time Frame: 5 years ]
    The frequency of lesions detected on PSMA PET according to the level of PSA at imaging


Other Outcome Measures:
  1. Proportion of men with oligometastatic recurrence (four or fewer sites including the prostate bed) on PMSA PET/CT who undergo lesion directed therapy [ Time Frame: 5 years ]

  2. To determine freedom from new systemic therapy in men undergoing targeted ablative therapy within 6 months after PSMA PET/CT [ Time Frame: 5 years ]
