Multiparametric magnetic resonance imaging/transrectal ultrasound fusion targeted biopsy of the prostate: Preliminary results of a prospective single-centre study - Abstract

Purpose: To evaluate multiparametric magnetic resonance imaging/transrectal ultrasound (mpMRI/TRUS) fusion targeted biopsy (TB) of the prostate for prostate cancer (PCa) diagnosis.

Patients and Methods: From April 2013 to January 2014, 53 men were included in this prospective single-centre study. The degree of PCa suspicion from mpMRI findings was classified according to the PI-RADS scoring system. Of these, 50 patients underwent both an mpMRI/TRUS fusion TB and a 10-core systematic biopsy (SB) of the prostate and were eligible for analysis.

Results: 225 targeted and 500 systematic cores were included in this study. PCa was histologically confirmed in 52.0% of patients (26/50), whereas TB revealed PCa in 46.0% (23/50) and SB in 36.0% (18/50). TB identified PCa in 16.0% of all patients (8/50) that were missed by SB. All told, the targeted core was 2.8 times more likely to be PCa-positive than the systematic core (29.3 vs. 10.4%).

Conclusions: mpMRI/TRUS fusion TB of the prostate is safe, practicable and may improve PCa diagnosis using fewer biopsy cores compared to SB.
