Biochemical Persistence of Prostate-specific Antigen after Robot-assisted Laparoscopic Radical Prostatectomy: Tumor localizations using PSMA PET/CT imaging

摘要

In the presence of BCP, a high proportion of patients already had disease metastatic to the pelvic lymph nodes or showed evidence of distant metastases, as indicated by PSMA PET/CT. Higher PSA levels after RARP and positive pathologic lymph node status were significantly associated with metastases outside the prostatic fossa. In patients with BCP, PSMA PET/CT imaging is warranted to guide salvage treatment strategies.
