研究概览
简要总结
Prostate cancer is the third most common cause of cancer death in men. Most patients with localized prostate cancer will be cured with surgery or radiation therapy, but up to 35% of patients will have their prostate cancer return.Current conventional imaging modalities have limitations particularly at low prostate specific antigen levels. This study proposes to use 68Ga-HTK03149 Dynamic Whole Body (DWB) Positron Emission Tomography / Magnetic Resonance Imaging (PET/MRI) scans which targets prostate-specific membrane antigens (PSMA) to detect where in the body the prostate cancer has recurred.
详细描述
This is a prospective registry study to evaluate the diagnostic utility of 68Ga-HTK03149 DWB PET/MRI to stage patients with high risk prostate cancer who will subsequently under go radical prostatectomy.
Eligible subjects will undergo a 68Ga-HTK03149 DWB PET/MRI at the University of British Columbia (UBC) - Vancouver, Djavad Mowafaghian Centre for Brain Health where the UBC PET/MRI is located. Each subject will receive a 18F-DCFPyL PET/MRI DWB scan at the UBC centre, as part of this research study. Each study subject will receive a bolus intravenous dose of 18F-DCFPyL. The subject will be placed on the PET/MRI scanner for a dynamic whole body PET scan. Then after a brief break off the scanner, they will return to the scanner for the standard whole body PET/MRI scan.
The PET/MRI scan will take approximately 3.5 hours of patient time above and beyond the time needed for standard of care.
Medical History Questionnaire: Demographic and medical history data will be collected either in person before the PET scan appointment or by mail or phone, whichever is the most convenient to the subject.
Follow-up assessments: All subjects will be contacted by phone the day after the injection of 68Ga-HTK03149. The subjects will be asked if they experienced any undesirable effects during the 12 hours after the administration of 68Ga-HTK03149. The local site attending nuclear medicine physician will then make an assessment as to whether these effects are likely related to 68Ga-HTK03149 administration.
