Background:
A radiotracer (or tracer) is a radioactive substance. It is used in Positron Emission Tomography (PET) imaging to help see specific sites in the body. Researchers want to learn if a new tracer can help them better identify hepatocellular cancer (HCC) in people.
Objective:
To learn if a radiotracer called 18F-DCFPyL can identify sites of HCC better than current standard imaging.
Eligibility:
Adults aged 18 years and older who may have HCC based on previous standard imaging.
Design:
Participants will be screened with a medical history, physical exam, and blood tests. They will have a computed tomography (CT) and/or magnetic resonance imaging (MRI) scan.
Participants will have a whole-body PET/CT scan. The PET and CT scanners use x-rays to make pictures of the inside of the body. The PET uses a tracer to help make the pictures. Participants will get an intravenous (IV) injection of 18F-DCFPyL 1 hour before the scan.
Within two weeks, participants will have a 18F-FDG PET/CT scan. 18F-FDG is a commonly used tracer. They will get 18F-FDG via IV 1 hour before the scan.
Participants will have a CT/MRI within 2 months of the first 18F-DCFPyL PET/CT.
Participants will have standard treatment for their cancer. During treatment, they will have a tumor biopsy. If the biopsy shows they do not have HCC, they will be removed from the study.
For participants who have HCC and their cancer was identified in the 18F-DCFPyL PET/CT, they will have a second 18F-DCFPyL PET/CT and 18F-FDG PET/CT.
Participants will have follow-up visits every 3 months for 2 years. Then they will have yearly visits for 3 years.

Drug: F18-FDG
Within approximately 2 weeks of each 18F-DCFPyL PET/CT scan, participants will be scanned with a 18F-FDG PET/CT imaging at the NIH Clinical Center using standard procedures. The 18F-FDG PET/CT imaging performed will allow the localization of viable tumor sites and characterize their FDG metabolism for comparison with 18F-DCFPyL imaging. The 18F-FDG PET/CT imaging will consist of an 18F-FDG injection and PET/CT imaging performed approximately 1 hour post 18F-FDG injection. A corresponding low dose CT scan for attenuation correction and co-registration purposes will be performed prior to the PET image. Device: MRI A standard of care CT and/or MRI will be performed within 2 months of each 18F-DCFPyL PET/CT. Device: CT A standard of care CT and/or MRI will be performed within 2 months of each 18F-DCFPyL PET/CT. Drug: F18-DCFPyL Each subject will receive a single IV dose of 18F-DCFPyL by bolus injection at a rate of approximately 1 ml/3-5 sec. The maximum amount of injected active drug will be less than 4.02 microgram. The target administered activity will be 9 mCi. The 18F-DCFPyL PET/CT imaging will consist of the 18F-DCFPyL injection, followed by a approximately 45 min dynamic CT imaging of a single bed position (including the liver lesion), and a static whole-body PET/CT imaging (top of head to mid-thighs) performed at 1 hour (+/- 10 minutes) post 18F-DCFPyL injection. Only a single injection of 18F-DCFPyL is required. The initial 45 minutes dynamic regional scan will be used to determine the kinetics of 18F-DCFPyL within the tumor as compared with normal liver and other background. |
- Positive predictive value [ Time Frame: Baseline, post ablation, disease progression ]The point estimates and 95% confidence intervals of the positive predictive value of 18F-DCFPyL PET/CT will be reported in which the confidence limits are the 2.5th and 97.5th percentile of the 2000 bootstrap samples obtained by random sample without replacement at the participant level to account for inter-lesion correlation.
- Lesion level sensitivity, specificity and positive predictive value [ Time Frame: Baseline, post ablation, disease progression ]The lesion level sensitivity, specificity and positive predictive value of 18F-DCFPyL PET/CT and CT/MRI will be calculated and compared. The confidence interval for each estimate will be obtained from the bootstrap samples and the difference in the estimates between the imaging modalities will be compared by the Wald test with the standard error calculated from the bootstrap samples.
- Change in 18F-DCFPyL PET/CT uptake between pre- and post-treatment [ Time Frame: Pre- and post-treatment HCC treatment ]change in 18F-DCFPyL PET/CT uptake between pre- and post-treatment will be compared by paired Wilcoxon test.

- INCLUSION CRITERIA:
- High radiological suspicion of hepatocellular carcinoma (LR4 or LR5 based on the most current version of LI-RADS) with at least one measurable lesion on standard imaging modality (CT and/or MRI).

- Individuals with a history of hepatitis C virus (HCV) infection must have been treated and cured.
- The effects of 18F-DCFPyL (study drug) on the developing human fetus are unknown. For this reason and because this agent as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for 2 months after each study PET/CT imaging. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.

- Other medical conditions deemed by the principal investigator (or associates) to make the subject unsafe/ineligible for protocol procedures.
- Subjects weighing > 350 lbs (weight limit for scanner table), or unable to fit within the imaging gantry
