title: [Value of MRI/ultrasound fusion in primary biopsy for the diagnosis of prostate cancer].
abstract: BACKGROUND
  Multiparametric magnetic resonance imaging (mpMRI) plays an emerging role in prostate cancer diagnosis. We compared the cancer detection rates of targeted biopsy (tB) of suspicious lesions in mpMRI versus systematic transperineal saturation biopsy (sB) in men with primary suspicion of prostate cancer (PCa).
  
  
  METHODS
  A total of 437 consecutive primary biopsy patients, who underwent transperineal systematic and fusion-guided biopsy between 2012 and 2014, were enrolled. mpMRI was evaluated based on PI-RADS. Analysis of biopsy specimen was performed following START criteria.
  
  
  RESULTS
  Of the 437 men, 334 harbored 426 MR lesions. Overall, 274 PCa and 203 significant PCa (Gleason score (GS) ≥ 3 + 4, GS = 3 + 3 and PSA values ≥ 10 ng/ml) were detected. There were 52 (26 %) significant PCa exclusively found by sB, whereas only 18 (9 %) were identified by tB (p < 0.001). Of 80 high-grade PCa with GS ≥ 4 + 3, 70 were diagnosed by sB, and 60 by tB (p = 0.007). In addition, 54 % of all insignificant PCa (GS < 7, PSA < 10 ng/ml) were detected by sB alone (p < 0.001). AUC of mpMRI was 0.76-0.78.
  
  
  CONCLUSIONS
  The combination of tB + sB detects PCa most accurately. Ongoing prospective (multicenter) studies are evaluating the status of the 12 core TRUS-guided random biopsy.
