Correlation Between SUV on 68Ga-HBED-CC-PSMA and Gleason Score in Prostate Cancer

March 3, 2018 updated by: Stephan Probst, Sir Mortimer B. Davis - Jewish General Hospital

Prostate cancer is the second leading cause of cancer death in North American men older than 50 years. Prostate specific membrane antigen (PSMA) is a unique membrane bound glycoprotein, which is overexpressed manifold on prostate cancer cells and is well-characterized as an imaging biomarker of prostate cancer. Positron emission tomography / computer tomography (PET/CT) is a nuclear medicine procedure based on the measurement of positron emission from radiolabeled tracer molecules. 68Ga-HBED-CC-PSMA (DKFZ-11) (abbreviated 68Ga-PSMA) is a tracer for prostate cancer PET imaging. The strength of functional imaging methods is in distinguishing tissues according to metabolism rather than structure. Studies have shown that PET/CT imaging with 68Ga-PSMA can detect prostate cancer lesions with excellent contrast and a high detection rate even when the level of prostate specific antigen is low.

Study Objectives:

The objective of this study is to evaluate if the patient-wide SUVmax on 68Ga-PSMA PET/CT in locoregional and metastatic prostate cancer correlates with histopathologic Gleason score at initial biopsy. It is hypothesized that SUVmax will correlate positively with Gleason score. This is of interest because non-invasive risk stratification may be possible in the future.

This will be a single-site JGH-only open label study in which one (1) 68Ga-PSMA PET/CT will be performed on study participants. A PET/CT scan takes 2-3 hours.
