Introduction & Objective : This study aims to compare the performance of urologists and radiologists on the use of multiparametric prostate magnetic resonance imaging (mp-MRI) directed cognitive systematic transrectal prostate biopsy (CSTPBx).
Methods : Between January 2017-January 2018, 349 mp-MRIs were performed at the department of radiology. One hundred and one patients who underwent mp-MRI directed CSTPBx for PIRADSv2 score 3, 4 and 5 lesions were included into this retrospective study. The patients were divided into two groups according to whether the biopsy was performed by urologist (Group 1, n=41) or radiologist (Group 2, n=60). Categoric and non-parametric continous variables were compared between two groups using chi-square and Mann-Whitney U tests, respectively.
Results : The patient age, clinical T stage, PSA, PSA density, prostate volume were similar in two groups. The proportion of PIRADSv2 score 3, 4 and 5 lesions were not statistically different between two groups. However, the relative increases of PIRADS 3 lesion in Group 1 (34.1 vs 15.0 %) and PIRADS 4 lesion in Group 2 (51.2 vs. 70.0 %) were notable. The pathology report did not significantly differ between two groups meanwhile the number of total cores were significantly higher in Group 1 (12 vs. 11, p=0.007). The proportion of Gleason Grade and positive core numbers in prostate cancer patients were not different between two groups.
This retrospective study showed that the performance of urologists and radiologists were similar on mp-MRI directed CSTPBx for Pca detection. However, the prospective studies with extended cohorts are needed to provide further suggestions.
