Abstract

This study aimed to describe the local recurrence (LR) pattern in post-prostatectomy prostate cancer patients using PSMA PET/CT scans. We retrospectively collected 103 PSMA PET/CT scans from patients with suspected LR across nine medical centres. Anonymized scans underwent review by an expert nuclear medicine physician. After review, on 83 PSMA PET/CT scans, 93 lesions were identified as a LR. The predominant LR location (56%) was found within 2 cm cranial to the penile bulb. Additionally, 24 LR (26%) were observed > 2 cm cranial to the penile bulb and caudal to the top of the pubic bone. Only 17 LR (18%) occurred cranial to the symphysis pubis. These findings contribute to the understanding of LR pattern post-prostatectomy, potentially optimizing accurate salvage radiotherapy to the prostate bed.
