Clinical Impact of PSMA PET Prior to Prostatectomy
Robert E. Reiter, MD, MBA, illustrates the diagnostic and predictive value of PSMA PET imaging and the role of PSMA as a biomarker. He begins by examining the sensitivity of PSMA PET against that of MRI and the benefits of using combined PSMA PET/MRI for intermediate-risk tumors.
Dr. Reiter then turns to the functionality of PSMA PET/CT as a predictor of clinical outcome. He presents data comparing pre- and post-prostatectomy PSMA and CAPRA-(S) scores in association with biochemical recurrence, noting that PSMA outperformed CAPRA-(S) scores in some situations.
Dr. Reiter concludes by examining the utility of PSMA as a biomarker for tumor biology and how that can inform treatment. He presents data comparing tumors with high PSMA expression against those with low PSMA expression. He notes that PSMA-high tumors are responsive to primary treatment, while low-PSMA tumors are likely to require secondary treatment.
