Aim: Magnetic resonance imaging (MRI) accuracy in prostate cancer (PCa) diagnosis in men submitted to saturation prostate biopsy (SPBx) was evaluated.
MATERIALS AND METHODS: 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.
RESULTS: 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 (p< 0.05).
CONCLUSION: Multiparametric MRI improved SPBx accuracy in diagnosing PCa of the anterior zone; moreover, suspicious areas >10 mm resulted as highly predictive of cancer (about 70% of the cases).
