OBJECTIVE: To assess the outcomes of multiparametric magnetic resonance imaging (mpMRI) transperineal targeted fusion biopsy (TPFBx) under local anaesthesia. PATIENTS AND METHODS: We prospectively screened 1327 patients with a positive mpMRI undergoing TPFBx (targeted cores and systematic cores) under local anaesthesia, at two tertiary referral institutions, between September 2016 and May 2019, for inclusion in the present study. Primary outcomes were detection of clinically significant prostate cancer (csPCa) defined as (1) International Society of Urological Pathologists (ISUP) grade >1 or ISUP grade 1 with >50% involvement of prostate cancer (PCa) in a single core or in >2 cores (D1) and (2) ISUP grade >1 PCa (D2). Secondary outcomes were: assessment of peri-procedural pain (numerical rating scale [NRS]) and procedure timings; erectile (International Index of Erectile Function) and urinary (International Prostate Symptom Score) function changes; and complications. We also investigated the value of systematic sampling and concordance with radical prostatectomy (RP). RESULTS: A total of 1014 patients were included, of whom csPCa was diagnosed in 39.4% (n = 400). The procedure was tolerable (NRS pain score 3.1 ± 2.3), with no impact on erectile (P = 0.45) or urinary (P = 0.58) function, and a low rate of complications (Clavien-Dindo grades 1 or 2, n = 8; grade >2, n = 0). No post-biopsy sepsis was recorded. Twenty-two men (95% confidence interval [CI] 17-29) needed to undergo additional systematic biopsy to diagnose one csPCa missed by targeted biopsies (D1). ISUP grade concordance of biopsies with RP was as follows: k = 0.40 (95% CI 0.31-0.49) for targeted cores alone and k = 0.65 (95% CI 0.57-0.72; P < 0.05) overall. CONCLUSIONS: The use of TPFBx under local anaesthesia yielded good csPCa detection and was feasible, quick, well tolerated and safe. Infectious risk was negligible. Addition of systematic to targeted cores may not be needed in all men, although it improves csPCa detection and concordance with RP.
