Brief Summary

The aim of this study was to investigate the value of dual-parameter magnetic resonance imaging(bpMRI) combined with regional saturation biopsy in the diagnosis of prostate cancer by means of a prospective randomized controlled study.

The main questions it aims to answer are:

Can bpMRI guide the timing of prostate puncture and avoid unnecessary prostate biopsy? Effectiveness of focal saturation biopsy versus systemic biopsy + targeted biopsy.

Conditions

Prostate Cancer

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: DIAGNOSTIC
• Blinding Strategy: SINGLE

Study Groups

MRI negative without biopsy

If a lesion with a PI-RADS score of 3 or higher was identified during the initial examination, a regional saturation biopsy of the prostate was conducted, as clinical suspicion of prostate cancer had been raised. Should the initial prostate biopsy yield negative results, the patient would be placed in the follow-up cohort. Targeted biopsy in conjunction with a 12-needle systematic biopsy would only be performed in cases where there was high suspicion of MRI persistence (a PI-RADS v2.1 score of 4 or 5) or if the lesion showed signs of progression. If no lesions with a PI-RADS v2.1 score of 3 or higher were detected during the initial examination, the patients would be entered into the follow-up cohort. Reginal saturation biopsy would be performed when MRI showed progression. If the initial prostate biopsy was negative, the patient would again be entered into the follow-up cohort.

Group Type: EXPERIMENTAL

Follow up if MRI is negative

Intervention Type: PROCEDURE

Enter the follow-up cohort without systematic biopsy when prostate cancer is clinically suspected and no PIRADS v2.1 score ≥3 lesions are detected on initial examination. MR plus regional saturation biopsy was performed when MRI progressed.

MRI negative with systemic biopsy

Focal saturation biopsy of the prostate was performed if a PI-RADS v2.1 score ≥3 lesion was detected during the initial examination. If no PIRADS v2.1 score ≥3 lesions were identified, a 12-needle systematic biopsy was performed. If the initial prostate biopsy was negative for prostate cancer, it was entered into the follow-up cohort. When the following clinical indications for repeat biopsy were met ① initial biopsy pathology showed no evidence of malignancy, but atypical small follicular hyperplasia was found, or high-grade epithelial neoplasia in more than 3 needles, with atypical glands visible in the surrounding area present; ② review of persistent elevation of serum PSA or abnormalities in the imaging follow up; and ③ review of serum PSA 4\~10 ng/ml in conjunction with f/t PSA, PSAD, PSAV, and PHI, abnormal rectal digital examination or other imaging findings, then target biopsy combined with 12-needle systemic biopsy was performed.

Group Type: ACTIVE_COMPARATOR

Systematic biopsy if MRI is negative

Intervention Type: PROCEDURE

Systematic biopsy was performed if there was clinical suspicion of prostate cancer and no PIRADS v2.1 score ≥3 lesions were detected on initial examination. If the biopsy was negative enter the follow-up cohort.

Interventions

Follow up if MRI is negative

Enter the follow-up cohort without systematic biopsy when prostate cancer is clinically suspected and no PIRADS v2.1 score ≥3 lesions are detected on initial examination. MR plus regional saturation biopsy was performed when MRI progressed.

Intervention Type: PROCEDURE

Systematic biopsy if MRI is negative

Systematic biopsy was performed if there was clinical suspicion of prostate cancer and no PIRADS v2.1 score ≥3 lesions were detected on initial examination. If the biopsy was negative enter the follow-up cohort.

Intervention Type: PROCEDURE
