Experimental: 18F-DCFPyL PET
We will have three separate sub-studies evaluating 18F-DCFPyL PET imaging of prostate cancer in three prostate cancer clinical scenarios under the following subheadings: (1) primary prostate cancer, (2) biochemical recurrence post-prostatectomy prior to radiation therapy, and (3) androgen-resistant metastatic disease.
Drug: 18F-DCFPyL PET
18F-DCFPyL PET demonstrates very high tumor-to-background and tumor specific uptake which may allow for a more sensitive and accurate method for detection of early tumor recurrence and metastatic disease as compared to current PET radiotracers and current standard-of-care imaging including 99mTc-methylene diphosphonate bone scintigraphy (bone scan), contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI).
- 18F-DCFPyL PSMA-based PET and multi-parametric MRI with DWI for sub-study #1: Primary Prostate Cancer [ Time Frame: Up to 12 months ]To evaluate the performance of 18F-DCFPyL PSMA-based PET and multi-parametric MRI (MP-MRI) with DWI (Diffusion Weighted Imaging) and gadolinium DCE (Dynamic Contrast Enhanced) using a dedicated PET/MRI scanner to detect clinically significant larger volume high-grade primary prostate cancer based on prostatectomy step-section pathology correlation.
- Evaluate 18F-DCFPyL PSMA-based PET for localization for sub-study #2: Biochemical Recurrence [ Time Frame: Up to 12 months ]To evaluate the performance of 18F-DCFPyL PSMA-based PET for localization of the site of recurrent prostate cancer in men with biochemical recurrence after definitive prostatectomy with planned salvage external-beam radiation therapy (EBRT). PSA response to prostatic fossa salvage irradiation will be compared with pre-salvage 18F-DCFPyL PET uptake in the radiation field.
- Compare detectability of 18F-DCFPyL for sub-study #3: Metastatic Androgen-Resistant Prostate Cancer [ Time Frame: Up to 12 months ]To compare the detectability of metastatic prostate cancer using 18F-DCFPyL PET obtained from PET/CT and PET/MRI compared to conventional imaging modalities (CIM) (bone scan and CT) in men with androgen-resistant prostate cancer.
- Sub-study #1: Detection of local-nodal and distant metastatic disease (PET [ Time Frame: Up to 12 months ]Evaluate the performance of 18F-DCFPyL PET and MRI whole body DWI for detection of local-nodal and distant metastatic disease on initial staging compared to conventional imaging modalities (CT and bone scintigraphy).
- Sub-study #1: Correlation of 18F-DCFPyL PET and MRI [ Time Frame: Up to 12 months ]Correlate 18F-DCFPyL PET standardized-uptake values (SUV) and MRI parameters with PSMA expression by prostatectomy pathology IHC.
- Sub-study #1: Specificity of 18F-DCFPyL [ Time Frame: Up to 12 months ]Evaluate the specificity of 18F-DCFPyL PET for differentiating primary prostate cancer versus non-malignant prostate lesions (BPH, prostatitis).
- Sub-study #1: Low-dose CT versus MRI derived PET SUV [ Time Frame: Up to 12 months ]Comparison of whole body low-dose CT and whole body MRI derived PET SUV-quantitation.
- Sub-study #2: Detection of local-nodal and distant metastatic disease (pelvic) [ Time Frame: Up to 12 months ]Comparison of whole body 18F-DCFPyL PET with pelvic MR-MRI and whole body DWI for detection of local-nodal and distant metastatic disease on initial staging compared to conventional imaging modalities (CT and bone scintigraphy).
- Sub-study #2: Dedicated pelvic 18F-DCFPyL PET/MRI with dynamic PET acquisition and multi-parametric MRI [ Time Frame: Up to 12 months ]Evaluate the performance of dedicated pelvic 18F-DCFPyL PET/MRI with dynamic PET acquisition and multi-parametric MRI for differentiation of urine versus recurrent malignancy in the prostatectomy bed.
- Sub-study #3: Contribution of whole body MRI DWI [ Time Frame: Up to 12 months ]Evaluate the contribution of whole body MRI DWI obtained from PET/MRI to improve the diagnostic performance of 18F-DCFPyL PET/CT and PET/MRI for metastatic prostate cancer lesion detection.
- Sub-study #3: Quantitative accuracy [ Time Frame: Up to 12 months ]Assess the quantitative accuracy of 18F-DCFPyL PET standardized uptake value parameters from PET/MRI versus PET/CT.
- Sub-study #3: Quantitative reproducibility [ Time Frame: Up to 12 months ]Assess the quantitative reproducibility of 18F-DCFPyL PET/CT derived-SUV values in normal organ and metastatic tumor lesions.
