Prospective Monitoring of Subjects With Biochemically Recurrent Prostate Cancer Using 18FDCFPyL
An observational study of Prostate Cancer and Biochemically Recurrent, run by National Cancer Institute (NCI) at 1 site in United States.
Trial summary
Background: Prostate cancer is the second leading cause of cancer-related death in American men. The disease recurs in up to 50,000 men each year after their early-stage disease was treated; however, at this stage, imaging scans are often unable to find the disease in the body.

About this study
Official title: A Study of Prospective Monitoring of Subjects With Biochemically Recurrent Prostate Cancer Using 18F-DCFPyL
Background:
Prostate cancer is the second leading cause of cancer-related death in American men. The disease recurs in up to 50,000 men each year after their early-stage disease was treated; however, at this stage, imaging scans are often unable to find the disease in the body. In this natural history study, researchers want to find out if a new radiotracer (18F-DCFPyL) injected before positron emission tomography (PET) imaging can help identify sites in the body with cancer.

Objective:
To learn more about how 18F-DCFPyL PET/CT scans detect change over time in men with recurrent prostate cancer.
Eligibility:
Men aged 18 and older with prostate cancer that returned after treatment.
Design:
Participants will be screened with blood tests. They will also have a bone scan and a computed tomography (CT) scans of the chest, abdomen, and pelvis.
Participants will have an initial study visit. They will have a physical exam and blood tests. They will have a PET/CT scan with 18F-DCFPyL. The radiotracer will be injected into a vein; this will take about 20 seconds. The PET/CT scan will be done 1 to 2 hours later. Participants will lie still on a scanner table while a machine captures images of their body. The scan will take 45 minutes.
Participants will return for blood tests every 3 months.
Participants will return for additional scans with 18F-DCFPyL on this schedule:
Once a year if their previous scan was negative for prostate cancer.
Every 6 months if their previous scan was positive for prostate cancer.
Participants may be in the study up to 5 years.
Read the detailed description
Background:
- Prostate cancer is the most common malignancy and the second leading cause of cancer-related deaths in American men.
- About 25,000 to 50,000 men each year develop a rising prostate-specific antigen (PSA) after definitive radiation or surgery for early-stage disease but have negative findings on computed tomography (CT) and Tc99 bone scan (standard imaging in prostate cancer).
- The recent Food and Drug Administration (FDA) approval of 18F-DCFPyL PET imaging provides an opportunity to locate micrometastatic lesions in patients with recurrent disease.
- It is unknown how these lesions (or prostate cancer) evolve over time in men with positive findings on 18F-DCFPyL PET imaging.
Objective:
-To observe participants with biochemically recurrent prostate cancer for 5 years to understand the evolution of 18F-DCFPyL PET lesions in this population.
Eligibility:
- History of primary treatment for prostate cancer (either surgery or radiation).
- PSA >= 0.50, and testosterone >100.
- Age >=18 years.
- No evidence of metastatic soft tissue disease on CT scan (or MRI), or bone lesions on bone scan.
- No androgen deprivation therapy (ADT), no systemic therapy within the 6 months before the study intervention, and no prostatectomy within 1 year before the study intervention. Clinical trial treatments are allowable within the 6 months before study intervention.
Design:
- Eligible participants will have clinical evaluations and imaging studies. Participants with negative findings on initial/following 18F-DCFPyL scan(s) will be invited approximately every year (+/-12 weeks) for follow-up imaging studies (including 18F-DCFPyL PET scans). Participants with positive findings on initial/following 18F-DCFPyL scan(s) will be invited approximately every 6 months (+/-8 weeks) for repeat scans, not to exceed 2 scans per year.
- After the initial evaluation, participants will be invited to NIH approximately every 3 months (+/- 4 weeks) for PSA testing.

What is being measured
The primary outcome is the main question the study is designed to answer.
Observation of 18F-DCFPyL lesions in BRPC

Measured: baseline through 5 years
Secondary outcomes (2)
Progression on 18F-DCFPyL
Initial 18F-DCFPyL imaging, every 6 months (+/- 8 weeks) for participants positive on imaging, and every 12 months (+/- 12 weeks) for participants negative on imaging until 5 years.
Measured: baseline through 5 years
Evaluate PSA doubling in association with 18F-DCFPyL changes
PSA test every 3 months (+/- 4 weeks) until 5 years.
Measured: baseline through 5 years
