But identification can be hard. Researchers want to see if a radiotracer used during PET scans can help.\n\nObjective:\n\nTo test how an imaging agent called 18F-DCFPyL detects response to standard prostate cancer treatment.\n\nEligibility:\n\nPeople ages 18 and older with newly diagnosed prostate cancer who have no evidence of distant metastatic disease and plan to get stereotactic body radiation therapy (SBRT) with or without androgen deprivation therapy (ADT).\n\nDesign:\n\nParticipants will be screened with:\n\nMedical history\n\nPhysical exam\n\nBlood tests\n\nMRI\n\nParticipants will have baseline MRI and PET\u002FCT scans. For the MRI, they may get a contrast agent by IV injection. For the PET\u002FCT scan, they will get an IV injection of 18FDCFPyL. About 1 to 2 hours later, they will get the PET\u002FCT scan. During the scans, participants will lie on their back and remain still for 45 minutes to 1 hour. These scans will be repeated at different points during the study.\n\nParticipants will get SBRT with or without ADT.\n\nParticipants will complete questionnaires about their quality of life.\n\nParticipants will be asked about any symptoms they are having. They will also be asked about medications they are using. They may have a physical exam.\n\nParticipants will give blood and urine samples. They will give a tumor sample from a biopsy they have had in the past.\n\nAfter treatment, participants will have follow-up visits. These will occur 1 month after treatment, then every 3 months for a year, and then every 6 months for 1 more year.",[74],"Localized Prostate Cancer",[74,76,77,78,79],"Radiotherapy","Prostate Specific Membrane Antigen","Androgen Deprivation Therapy","longitudinal quality of life","2026-06-23",{"date":82,"type":83},"2026-06-24","ACTUAL",{"date":85,"type":83},"2022-08-31",{"date":87,"type":68},"2029-12-31",{"name":24,"class":6},1]
