Summary
Brief summary (as posted)
The goal of this prospective, single-center, single-arm trial is to evaluate the positive predictive values between 18F-PSMA-1007 PET/CT based on diagnostic model in patients with suspicious of prostate cancer. The main question and our aim to answer is: • Can these patients with clinically significant prostate cancer in 18F-PSMA-1007 PET/CT based on diagnostic model undergo radical prostatectomy directly without prostate biopsy. Participants will be asked to accomplish the test of serum PSA, mpMRI, then, the eligible patients (The probability of the diagnostic model to predict clinically significant prostate cancer was greater than or equal to 60 percent) need perform 18F-PSMA-1007 PET/CT. Finally, patients will receive radical prostatectomy directly if prostate cancer is considered by 18F-PSMA-1007 PET/CT.

- 18F-PSMA-1007 PET/CT based on USTC diagnostic model
- description
- Patinets will complete the 18F-PSMA-1007 PET/CT based USTC diagnostic model firstly. If clinically significant prostate cancer is considered by 18F-PSMA-1007 PET/CT. Patinets will receive radical prostatectomy directly or undergo prostate biopsy according to patients own decisions, patients with negative results in prostate biopsy will be asked to complete rebiopsy after 3 months.
