Study Arms (4)
PET+/mpMRI+ group
EXPERIMENTALPatients in this group will undergo 68Ga-PSMA PET/mpMRI imaging, and the results show positive findings on both PSMA PET and mpMRI. These patients will undergo prostate biopsy guided by PSMA PET/CT.
PET+/mpMRI- group
EXPERIMENTALPatients in this group will undergo 68Ga-PSMA PET/mpMRI imaging, and the results show positive findings on PSMA PET and negative on mpMRI. These patients will undergo prostate biopsy guided by PSMA PET/CT.
PET-/mpMRI+ group
ACTIVE COMPARATORPatients in this group will undergo 68Ga-PSMA PET/mpMRI imaging, and the results show negative findings on PSMA PET and positive on mpMRI. These patients will undergo prostate biopsy guided by mpMRI and US.
PET-/mpMRI- group
PLACEBO COMPARATORPatients in this group will undergo 68Ga-PSMA PET/mpMRI imaging, and the results show negative findings on both PSMA PET and mpMRI. These patients will undergo systematic prostate biopsy.
Interventions
The patient will undergo pelvic non-contrast CT imaging. After co-registration of the CT images with 68Ga-PSMA PET/CT data at corresponding anatomical levels, a percutaneous gluteal approach will be utilized for CT-guided prostate biopsy.
The patient will undergo transrectal ultrasound (TRUS) prostate scanning. After co-registration and precise image fusion of TRUS findings with multiparametric MRI (mpMRI) data, a transperineal percutaneous approach will be employed to perform TRUS-guided prostate biopsy.
The patient will undergo systematic prostate biopsy under TRUS guidance.
Eligibility Criteria
You may qualify if:
- Age ≥40 years, male;
- Serum PSA level 4-20 ng/mL;
- Serum PSA level 4-20 ng/mL;
- No contraindications to PSMA-PET/CT or MRI;
- Signed informed consent.
You may not qualify if:
- Serum PSA \>20 ng/mL;
- History of prostate surgery/radiotherapy;
- Acute prostatitis;
- Coagulation disorders or active infection;
- Severe internal/external hemorrhoids, perianal, rectal, or gluteal lesions;
- Allergy to local anesthetics;
- Inability to tolerate the biopsy procedure.
