Prostate Cancer Clinical Trial

Official title: Advanced Prostate Imaging of Recurrent Cancer After Radiotherapy

Status Completed

Clinical Trial Summary

The investigators are attempting to determine if a new form of imaging called 18F-DCFPyL PET/CT is helpful to physicians in deciding how to manage suspected prostate cancer recurrence. This imaging uses a Positron Emission Tomography/Computed Tomography (PET/CT) scan using a radioactive tracer 18F-DCFPyL that is concentrated in prostate cancer cells and can potentially identify cancer cells throughout the body. The combination of 18F-DCFPyL PET/CT can potentially identify areas of prostate cancer recurrence not seen with usual imaging [bone scan, computed tomography (CT) thorax, abdomen and pelvis, plus multi-parametric magnetic resonance imaging (MRI)].

Clinical Trial Description

The study will evaluate the utility of investigational restaging with 18F-DCFPyL PET/CT following conventional imaging (bone scan, CT thorax, abdomen and pelvis plus multi-parametric pelvic MRI) in detecting the prevalence of metastatic disease among men with biochemical recurrence after radical radiotherapy treatment to the prostate. Men treated with primary radiation with external beam or brachytherapy will be eligible. Eighty (80) eligible consenting patients with biochemical recurrence and potentially suitable for local salvage or targeted ablative therapies will be registered and imaged with conventional imaging (bone scan, CT thorax, abdomen and pelvis plus multi-parametric pelvic MRI) followed by investigational restaging with 18F-DCFPyL PET/CT. Characterizing sites of disease identified by the combination of 18F-DCFPyL PET/CT with conventional imaging versus 18F-DCFPyL PET/CT alone will be used to explore the potential of 18F-DCFPyL PET/CT as a single restaging study in men with biochemical recurrence. While further investigation and treatment after restaging will be at the discretion of the investigator and the patient, the actual treatment/management, treatment outcomes and quality of life will be recorded in an electronic database at 6, 12, 24 and 36 months after re-staging. Such longitudinal analyses of management and outcomes will be useful in characterizing the disease trajectory, response to treatment and quality of life for patients whose recurrent disease is managed based on comprehensive restaging using the combination of conventional imaging and 18F-DCFPyL PET/CT. ;
