The aim of our study was to assess the learning curve (LC) of two urology residents in the execution of fusion biopsy (FB) considering overall prostate cancer (PCa) and clinically significant (cs) PCa detection rate (DR), based on different lesions’ characteristics at the MRI. METHODS: We extracted data from our prospectively maintained database from January 2015 to December 2019. FB was carried out with the BioJet fusion system (D&K Technologies, Barum, Germany) either by a transrectal or transperineal approach. An ANOVA test was used to assess the homogeneity of the cohort. Multivariable linear and logistic regression analysis were used to assess the correlation between operator experience and DR for PCa and csPCa. At last, the postprocedural complication rate trend was determined. RESULTS: 1005 men were enrolled in the study. During the five years of the study, the pre-biopsy characteristics of the patients enrolled did not change significantly except for the proportion of patients who previously underwent prostate biopsy (p<0.001) and the number of mpMRI performed at referral centers (p=0.002), both showing a decreasing trend over time. The overall DR of PCa was 61.2% (615/1005) [IC 0.58-0.64]; whilst DR for csPCA was 54.6% (549/1005) [IC 0.51–0.57]. Operator experience does not appear to impact the DR of overall PCa and csPCa. On the contrary, in case of lesions with diameter <8 mm, PCa and csPCa DR were significantly higher with operator experience (p=0.048 and p=0.038, respectively). Considering the suspicious tumours located in the more challenging areas of the prostate (transitional or posterolateral zone) were not significantly better diagnosed with experience improvement (p=0.34 and p=0.22 for PCa DR and csPCa DR respectively). The specific analysis focused on PI-RADS 5 lesions, mpMRI performed in referral centers, or for patients at repeated-biopsy did not reveal a significant relationship between operator experience and PCa or csPCa DR. Complication rate was stable during the whole study (p=0.75). CONCLUSIONS: A standardized FB approach demonstrated to be feasible, safe, and effective since the start of residents’ LC. PCa and csPCa DR was stable, after > 1000 biopsies. Nevertheless, in case of lesions < 8 mm, the execution of at least 100 FB is fundamental in order to correctly sample the area.
