“…Therefore, PSMA radiopharmaceuticals have been increasingly used to detect small tumor lesions, lymph node, bone, or visceral metastases because of its high sensitivity even at low PSA levels. Several PSMA radioligands such as Gallium-68 (68Ga), Fluorine-18 (18F), Lutetium-177 (177Lu), or Copper-64 (64Cu) are currently available to obtain effective radiotherapeutics for theranostic applications (16)(17)(18)(19)(20). 68Ga-PSMA PET/CT Abbreviations: PSMA, prostate-specific membrane antigen; PET/CT, positron emission tomography/computed tomography; BRPCa, biochemically recurrent prostate cancer; CI, confidence interval; DR, detection rate; PSA, prostatespecific antigen; PCa, prostate cancer; BCR, biochemical recurrence; RP, radical prostatectomy; EBRT, external beam radiation therapy; RT, radiation therapy; PRISMA, Preferred Reporting Items for Systematic Reviews and Meta-analyses; QUADAS-2, quality assessment of diagnostic accuracy studies;…”
