Official title
Application of PSMA PET/MRI-guided Prostate Targeted Biopsy in Patients With PI-RADS ≤ 3 and Negative Previous Biopsy: A Single-center, Prospective, Open-label, Randomized Controlled Trial
Overview
The goal is to provide more accurate diagnostic tools and optimized diagnostic workflows for clinically suspected prostate cancer patients with prior negative biopsies, improving early detection rates for csPCa and reducing missed diagnoses.
Detailed description
This research intends to prospectively enroll patients with prior negative biopsies, a PI-RADS score ≤ 3, and persistent PSA or PHI elevation, randomly assigning them to the PSMA PET/MRI group (experimental group) and the TRUS-guided transperineal saturation biopsy group (control group). The research aims to evaluate the application of PSMA PET/MRI in clinically suspected prostate cancer patients with prior negative biopsies, comparing the differences in csPCa detection rates between PSMA PET/MRI-TRUS guided prostate targeted biopsy and TRUS-guided saturation biopsy.
Interventions
- Diagnostic test PSMA PET/MRI-TRUS guided prostate targeted combined saturation biopsy
The experimental group will undergo PSMA PET/MRI examination. For those with positive PSMA PET/MRI results, a PSMA PET/MRI-TRUS guided prostate targeted biopsy will be performed based on transrectal ultrasound (TRUS) guided transperineal saturation biopsy, targeting the positive lesions. For those with negative PSMA PET/MRI results, only TRUS guided transperineal saturation biopsy will be performed. Clinical and pathological data of the patients will be collected for statistical analysis. - Diagnostic test TRUS guided transperineal saturation biopsy
The control group will receive TRUS guided transperineal saturation biopsy. Clinical and pathological data of the patients will be collected for statistical analysis.
Primary outcome measures

- EORTC QLQ-C30 Questionnaire [Time frame: Before diagnosis, 1 month, 3 months, 6 months, 12 months]
- Generalized Anxiety Disorder GAD-7 Scale [Time frame: Before diagnosis, 1 week after diagnosis, 1 month, 3 months, 6 months, 12 months]
- Decision Conflict Scale, Decision Regret Scale [Time frame: Before diagnosis, 1 month, 3 months, 6 months]
