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.

Outcome Measures
Primary Outcomes (2)
Frequency of disease detection on PSMA PET
Phase 1: 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 Phase 2: 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 when PSMA PET/CT is used without routine pre-screening with conventional imaging.
5 years
To determine the proportion of men who have "actionable disease" identified on PSMA PET with [18F]-DCFPyL or [18F]PSMA-1007.
Phase 3: Actionable disease is defined as PET identified lesions where targeted therapy with radiation, surgery or other focal, PET lesion directed intervention (i.e. biopsy) is possible (men with oligometastatic and/or locoregional disease only).
5 years
Secondary Outcomes (13)
Determine correlations between PSA levels at time of study enrollment and presence of disease detected on PSMA PET
5 years
Proportion of men with oligometastatic recurrence (four or fewer sites including the prostate bed if positive) confirmed on PSMA PET/CT
5 years
Number of men who have their management plan changed because of PSMA PET results
5 years
To determine the actual management delivered within 6 months of PSMA PET
5 years
Compare PSA response at 6 months against PSA at the time of PSMA PET
5 years
- +8 more secondary outcomes
Study Arms (9)
Cohort 1
EXPERIMENTALMen who are node positive or who have persistently detectable PSA after initial radical prostatectomy will be restaged with \[18F\]-DCFPyL or \[18F\]PSMA-1007 PET/ CT scan (PSMA PET)
Cohort 2
EXPERIMENTALMen with biochemical failure after initial prostatectomy will be restaged with \[18F\]-DCFPyL or \[18F\]PSMA-1007 PET/ CT scan (PSMA PET)
Cohort 3
EXPERIMENTALMen with biochemical failure after initial radical prostatectomy and salvage radiotherapy will be restaged with \[18F\]-DCFPyL or \[18F\]PSMA-1007 PET/ CT scan (PSMA PET)
Cohort 4
EXPERIMENTALMen with biochemical failure after initial radical prostatectomy with or without adjuvant/ salvage radiotherapy who are currently on salvage hormone therapy will be restaged with \[18F\]-DCFPyL or \[18F\]PSMA-1007 PET/ CT scan (PSMA PET)
Cohort 5
EXPERIMENTALMen who have prior PSMA directed treatment for oligometastatic disease, such as lesion directed therapy (e.g. stereotactic radiosurgery) or systemic therapy (e.g. hormone therapy or chemotherapy) with subsequent biochemical failure will be restaged with \[18F\]-DCFPyL or \[18F\]PSMA-1007 PET/ CT scan (PSMA PET)
Cohort 6
EXPERIMENTALMen with biochemical failure after primary radiation therapy (external beam, brachytherapy or combinations together with or without hormone therapy) will be restaged with \[18F\]-DCFPyL or \[18F\]PSMA-1007 PET/ CT scan (PSMA PET)
Cohort 7
EXPERIMENTAL\[18F\]-DCFPyL or \[18F\]PSMA-1007 as a problem-solving tool in patients with prostate cancer when confirmation of the site of disease and/or disease extent may impact clinical management. Patients in this cohort require approval from an independent adjudication by Cancer Care Ontario.
Cohort 0
EXPERIMENTALInitial staging with \[18F\]-DCFPyL or \[18F\]PSMA-1007 PET/ CT scan (PSMA PET) for high risk men being evaluated for primary therapy with surgery or radiation. Men with adverse clinical staging features (cT3, PSA \>20, Gleason Grade Group 4-5) have a higher risk of extra-prostatic spread and rates of clinical failure with prostate only directed treatment (surgery or radiation).
Cohort 8
EXPERIMENTALMen with castrate resistant prostate cancer with progression after at least one line of second line hormone therapy or taxane therapy. PSMA targeting PET/CT will be used to assess if men accrued would meet the imaging biomarker eligibility criteria for RLT as published by Sartor (Sartor, 2021).
Interventions
Participants will undergo re-staging with \[18F\]-DCFPyL or \[18F\]PSMA-1007 PET/CT Scan (PSMA PET).
Eligibility Criteria
You may qualify if:
- Written informed consent obtained
- Male, Age ≥ 18 years
- Prior primary treatment for prostate cancer with curative intent such as radical prostatectomy or radiotherapy for localized prostate cancer. Unless PET/CT requested as part of Cohort 7.
- Suspected persistent or recurrent disease defined as one of the following (unless PET/CT requested as part of Cohort 7):
- High risk disease at the time of radical prostatectomy characterized by pathologically involved node(s) or persistently detectable PSA (\>0.1ng/ml) within 3 months post-surgery
- Primary treatment for prostate cancer and biochemical failure (BF) with current management according to the following:
- i. Following primary radical prostatectomy, BF is defined as rising PSA on at least 2 occasions measured at least 1 month apart and with the most recent PSA measured at \>0.1 ng/ml
- ii. Following primary radiotherapy for localized disease, BF is defined according to the Phoenix Definition, which is rising PSA on at least 2 occasions measured at least 1 month apart and with the most recent PSA measured greater than the nadir PSA + 2.0 ng/ml
- Patient scenario falls into one of the 7 pre-defined cohorts. When patient scenario falls outside cohorts 1-6 participation in the Registry must be approved through the established CCO adjudication process for Cohort 7.
- Karnofsky performance status 70 or better (ECOG 0, 1).
- If PSA \>10 mg/mL, conventional imaging consisting of bone scan and abdo-pelvic CT scan within 3 months of registration that is either equivocal, negative (no lesions) or positive for oligometastatic disease (4 or fewer unequivocal lesions identified).
You may not qualify if:
- Prostate cancer with significant sarcomatoid or spindle cell or neuroendocrine small cell components.
- Prior PSMA PET scan within 6 months of enrollment.
- Patient cannot lie still for at least 60 minutes or comply with imaging.
- Patients falling outside of Cohorts 1-6 where independent adjudication by CCO does not support participation in the Registry.
- Phase 3
- Written informed consent obtained
- Male, Age ≥ 18 years
- Biopsy proven, clinically high risk (cT3, PSA ≥20, biopsy Gleason Grade Group 4-5) prostate cancer undergoing initial staging prior to primary treatment with surgery or radiotherapy
- Biochemical failure (BF) with current management defined as at least two consecutive rises in PSA measured at least 1 month apart with the most recent PSA level \>0.1 ng/ml (post radical prostatectomy or post PSMA Directed therapy, Cohorts 1-5) or PSA level \> nadir PSA + 2.0 ng/ml (Phoenix definition post radiotherapy failure, Cohorts 5, 6)
- Men with rising PSA and/or progression on conventional imaging despite prior second line hormone therapy or chemotherapy for castrate resistant prostate cancer (Cohort 8).
- PET/CT requested as part of Cohort 7.
- Patient scenario falls into one of the 8 pre-defined cohorts. When patient scenario falls outside cohorts 0-6 and 8, participation in the Registry must be approved through the established CCO adjudication process for Cohort 7.
- Karnofsky performance status 70 or better (ECOG 0, 1)
- If recurrent disease suspected and PSA prior to PSMA PET/CT is \>10 ng/ml, conventional imaging consisting of bone scan and abdominal-pelvic CT scan performed within 3 months of registration that is either equivocal, negative (no lesions) or positive for oligometastatic disease (4 or fewer unequivocal lesions identified). Registration is defined as Form A: Eligibility is complete.
- If patient is enrolled in Cohort 8, conventional imaging consisting of at least bone scan and abdominal-pelvic CT scan completed within 3 months of registration. Registration is defined as Form A: Eligibility is complete.
