Introduction: The reclassification rate for clinically significant prostate cancer (csPCa) in men enrolled in Active Surveillance (AS) as been prospectively evaluated.
Patients and methods: One hundred patients with very low risk PCa underwent after 8 years a scheduled transperineal prostate biopsy (SPBx = 20 cores) combined with additional mpMRI/TRUS fusion biopsies (4 cores) of lesions PI-RADS scores ≥ 3. All the patients, after initial diagnosis, previously had mpMRI evaluation combined with transperineal saturation prostate biopsy (confirmatory and 3-year scheduled biopsy). Risk reclassification at repeat biopsy triggering the recommen-dation for active treatment was defined as over 3 or more than 10% of positive cores, Gleason score > 6/ISUP Grade Group ≥ 2, greatest percentage of cancer (GPC) > 50%.
Results: Multiparametric MRI was suspicious (PI-RADS ≥ 3) in 30 of 100 cases (30.0%); 70 (70.0%) vs. 20 (20.0%) vs. 10 (10.0%) patients had a PI-RADS score ≤ 2 vs. 3 vs. 4, respec-tively. Two (2.0%) patients with PI-RADS score 3 and 4 were upgraded (ISUP Grade Group 2); SPBx and MRI/TRUS fusion biopsy diagnosed 100% and 0% of csPCa, respectively.
Conclusions: Transperineal SPBx combined with mpMRI at ini-tial confirmatory biopsy allow to select an high number of men at very low risk of reclassification during the AS follow up (2.0%of the cases at 8 years from diagnosis); these data could be use-ful to reduce the number of scheduled repeated prostate biopsy during the AS follow up.
