Prostate Cancer Clinical Trial
— ADTPSMAOfficial title:
The Effect of Androgen Deprivation Therapy on Prostate Specific Membrane Antigen (PSMA) in Prostate Cancer
Phase A: To describe and to determine the maximum standardised uptake values (SUV) in
prostate specific membrane antigen positron emission tomography (PSMA-PET) before ADT and 7,
14 and 28 days after ADT.
Phase B: To validate phase A results by comparing the PSMA-PET findings to histopathological
analysis of regional lymph nodes acquired from radical prostatectomy specimens. PSMA-PET is
done before ADT and at maximum SUV defined by the phase A.
