Objectives: To systematically assess the early detection rate of biochemical prostate cancer recurrence using choline, fluciclovine, and PSMA.
Methods: Under the guidance of the Preferred Reporting Items for Systematic reviews and Meta-Analysis Diagnostic Test Accuracy guidelines, literature that assessed the detection rates (DRs) of choline, fluciclovine, and PSMA in prostate cancer biochemical recurrence was searched in PubMed and EMBASE databases for our systematic review from 2012 to July 15, 2021. In addition, the PSA-stratified performance of detection positivity was obtained to assess the DRs for various methods, including fluciclovine, PSMA, or choline PET/CT, with respect to biochemical recurrence based on different PSA levels.
Results: In total, 64 studies involving 11,173 patients met the inclusion criteria. Of the studies, 12, 7, and 48 focused on choline, fluciclovine, and PSMA, respectively. The pooled DRs were 24%, 37%, and 44%, respectively, for a PSA level less than 0.5 ng/mL (p < 0.001); 36%, 44%, and 60% for a PSA level of 0.5-0.99 ng/mL (p < 0.001); and 50%, 61%, and 80% for a PSA level of 1.0-1.99 ng/mL (p < 0.001). The DR with F-labeled PSMA was higher than that with Ga-labeled PSMA, and the DR was 58%, 72%, and 88% for PSA levels < 0.5 ng/mL, 0.5-0.9 ng/mL, and 1.0-1.99 ng/mL, respectively.
Conclusion: The DRs of PSMA-radiotracers were greater than those of choline-radiotracers and fluciclovine-radiotracers at the patient level. F-labeled PSMA achieved a higher DR than Ga-labeled PSMA.
Key Points: • The DRs of PSMA-radiotracers were greater than those of choline-radiotracers and fluciclovine-radiotracers at the patient level. • F-labeled PSMA achieved a higher DR than Ga-labeled PSMA.

This article provides a comprehensive overview of the current treatment options for patients with metastatic castration-resistant prostate cancer (mCRPC) following the failure of first-line therapy. Although significant progress has been made in the primary treatment of hormone-sensitive prostate cancer, the management of mCRPC remains a clinical challenge. The article outlines the diagnostic criteria for mCRPC, which can be confirmed through biochemical progression and imaging techniques.

Introduction: Prostate cancer guidelines recommend molecular analysis of biomaterial following resistance to first-line systemic therapy in order to identify druggable mutations. We report on our results of molecular analysis of tissue specimens via next generation sequencing (NGS) in men with metastatic castration resistant prostate cancer (mCRPC).
Patients And Methods: In all, 311 mCRPC patients underwent NGS analysis from biopsy samples of progressive metastatic lesions or archival radical prostatectomy specimens.

Background: Current approach to clinically suspicious biopsy-naïve men consists performing prostate MRI, followed by combined systematic (TRUS-Bx) and MRI-Ultrasound fusion biopsy (MRI-TBx) in those with PIRADS score ≥ 3. Researchers have attempted to determine who benefits from each biopsy method, but the results do not support the safe use of one method alone. This study aims to determine the optimal approach in biopsy-naïve men, according to their PSA levels.
