  • Title: Can Ga-68 PSMA PET/CT replace conventional imaging modalities for primary lymph node and bone staging of prostate cancer?

    Journal: Eur Urol Focus; 2020 Mar 15; 6(2):218-220. PubMed ID: 31113757.
    Abstract:
    Imaging is critical for primary staging of prostate cancer. Traditional imaging modalities (computerized tomography scan and nuclear medicine bone scans) are limited by their suboptimal diagnostic performance. Recent meta-analyses have demonstrated that nuclear imaging with 68Ga-labeled prostate-specific membrane antigen ligand (68Ga-PSMA) using positron emission tomography/computed tomography (PET/CT) has higher sensitivity and specificity in this setting compared to conventional imaging techniques. 68Ga-PSMA PET/CT for whole-body assessment can be used as the sole imaging modality for primary lymph node and bone staging of prostate cancer. PATIENT SUMMARY: There is a rapidly growing body of evidence that nuclear imaging with 68Ga-labeled prostate-specific membrane antigen ligand using positron emission tomography/computed tomography has a higher detection rate for lymph node and bone metastases in prostate cancer patients. This approach has strong potential to replace conventional techniques in the primary setting in the near future.
