89Zr-PSMA-617 PET/CT May Reveal Local Recurrence of Prostate Cancer Unidentified by 68Ga-PSMA-11 PET/CT

Clin Nucl Med. 2022 May 1;47(5):435-436. doi: 10.1097/RLU.0000000000004108.

Abstract

For localization of biochemical recurrence of prostate cancer, 68Ga-PSMA-11 PET/CT imaging was performed in a 66-year-old man with no suspicious findings at 1 hour p.i. Additional 89Zr-PSMA-617 PET/CT revealed a small local recurrence in the prostate bed, facilitating consecutive local therapy. This interesting image points to the potential of PET/CT with 89Zr-labeled PSMA ligands, for example, 89Zr-PSMA-617, for identifying the source of biochemical recurrence despite otherwise negative imaging including conventional PSMA PET/CT.
