The factors determining positive detection rate of 68Ga PSMA PET/CT in patients with early biochemical recurrence prostate cancer

Abstract

Abstract Aim To examine predictive markers for high detection rates of 68Ga PSMA-PET/CT in biochemical recurrence (BR) prostate cancer (PCa) patients with low PSA levels. Material and Method This trial was planned as a retrospective single center study. Patients with BR prostat cancer were included. PSA levels of all patients were lower 2\u202fμg/l. Results Totally thirty-two men patients with BR PCa were included in this study. 18 (56.3%) patients underwent radical prostatectomy and 14 (43.7%) patients curative intense radiotherapy. The number of patients received adjuvant maximal androgen blokage (MAB) treatment was 15 (46.9%). Median PSA levels was calculated 1.03\u202fμg/l 17 (53.1%) of patients had Conclusion Clinicians may perform 68Ga PSMA PET/CT in low PSA levels to detect lesions in biochemical recurrent prostate cancer patients who had received MAB treatment and in patients with higher PSA levels who had no received MAB treatment.
