Prostate cancer detection at repeat biopsy: can pelvic phased-array multiparametric MRI replace saturation biopsy?

Magnetic resonance imaging (MRI) accuracy in prostate cancer (PCa) diagnosis in men submitted to saturation prostate biopsy (SPBx) was evaluated. From June 2011 to December 2012, 78 patients (median 63 years) underwent repeat SPBx (median 28 cores). Multiparametric MRI using a 3 Tesla pelvic phased-...

Description
Summary:Magnetic resonance imaging (MRI) accuracy in prostate cancer (PCa) diagnosis in men submitted to saturation prostate biopsy (SPBx) was evaluated. From June 2011 to December 2012, 78 patients (median 63 years) underwent repeat SPBx (median 28 cores). Multiparametric MRI using a 3 Tesla pelvic phased-array coil was performed before SPBx and lesions suspicious for PCa were submitted to additional targeted biopsies. A T1c PCa was found in 32 (41%) cases. SPBx vs. MRI-suspicious targeted biopsy diagnosed 28 (87.5%) vs. 26 (81.2%) PCa missing four (12.5%) and six (18.8%) cancers localized in the anterior zone and in the lateral margin of the prostate, respectively; moreover, MRI diameter lesions correlated with PCa diagnosis and Gleason score (p10 mm resulted as highly predictive of cancer (about 70% of the cases).
