Optimizing Combined Magnetic Resonance Imaging (MRI)-Targeted and Systematic Biopsy Strategies: Sparing the Multiparametric MRI-Negative Transitional Zone in Presence of Exclusively Peripheral Multiparametric MRI-Suspect Lesions.

We assessed whether sampling of the transitional zone can be spared in patients with exclusively peripheral prostate cancer (PCa)-suspicious multiparametric magnetic resonance imaging (mpMRI) lesions who undergo combined mpMRI targeted (TBx) and systematic prostate biopsies (SBx).Of 1,685 patients who underwent extended SBx including transitional zone sampling and had TBx of ≥1 lesion in the peripheral and/or transitional zone, we selected 863...
