Study Details

Study Description

Brief Summary

This research study wants to develop advanced imaging methods to more accurately characterize prostate cancer or solid tumor aggressiveness.

This observational study involves [18F]DCFPyL positron emission tomography and magnetic resonance imaging (PET/MRI)

Condition or Disease	Intervention/Treatment	Phase
Adenocarcinoma of Prostate Radical Prostatectomy Hepatocellular Carcinoma (HCC) Glioma Renal Cell Carcinoma (RCC) Prostate Cancer	Drug: [18F]DCFPyL Radiation: PET/MRI scanner

Detailed Description

This is an observational imaging study to evaluate the value of multimodal [18F]DCFPyL positron emission tomography and magnetic resonance imaging (PET/MRI) for solid tumor characterization and disease staging.

This research study involves:

Screening visit, and 1-3 study Multimodal [18F]DCFPyL PET/MRI visits
Two cohorts of participants will be enrolled in this study: primary prostate cancer patients and patients with known or suspected solid tumors (hepatocellular carcinoma, glioma, clear cell renal carcinoma)
It is expected that about 135 people will take part in this research study
The PET dye used in this study is called [18F]DCFPyL. [18F]DCFPyL is approved by the U.S. Food and Drug administration (FDA).
The PET/MRI scanner was approved by the U.S. FDA.

Outcome Measures

Primary Outcome Measures

Diagnostic value of multimodal imaging in primary prostate cancer patients [3 Days]
First tumor aggressiveness will be identified by binarizing the Gleason grade scores (GG ≥ 3+4). Binarized tumor aggressiveness obtained from the machine learning techniques will be then compared to the gold-standard, histopathology.

Secondary Outcome Measures

Scan-rescan repeatability [6 months]
Repeated measures analysis of covariance (ANCOVA) to evaluate statistical significance using a multilevel analysis to accommodate the nested structure of the data (longitudinal correlated data). Wilcoxon signed rank test will be used to assess for differences in each imaging parameter across visits. Spearman rank correlation will be used to test the correlation between [18F]-DCFPyL binding as measured by standardized uptake values (SUV) and Ktrans or SUV and cerebral blood flow (CBF). The false discovery rate will be used to adjust for multiple testing.

Eligibility Criteria

Criteria

Ages Eligible for Study:

18 Years and Older

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

Inclusion Criteria:

Participants must meet the following criteria on screening examination to be eligible to participate in the study:
Must have primary prostate cancer (e.g. adenocarcinoma of prostate) and deemed a candidate for radical prostatectomy as part of standard clinical care for Cohort

Must have evidence or be suspected of having HCC, Glioma and RCC for enrollment in Cohort B.
Age ≥18 years.

--- Because no dosing or adverse event data are currently available on the use of [18F]DCFPyL in participants <18 years of age, children are excluded from this study, but will be eligible for future pediatric trials.

Participants must have adequate kidney function for gadolinium-based contrast administration as assessed by:
estimated or measured glomerular filtration rate (GFR) ≥ 60 mL/min/1.73 m2 for repeated administrations.
a single dose will be administered to subjects with a GFR between 30-60 mL/min/1.73 m2. Investigators will not repeat the gadolinium-based contrast agent administration until the renal function improves and the GFR is higher than 60 cc/min/1.73 m2. These subjects will not undergo examinations on consecutive days even if the renal function improves.
Patient must be able to undergo MRI and PET scans.
