COMPARISON OF MAGNETIC RESONANCE IMAGING-TRANSRECTAL ULTRASOUND FUSION PROSTATE BIOPSY WITH STANDARD SYSTEMATIC BIOPSY: A SINGLE CENTER EXPERIENCE

OBJECTIVE: To compare systematic biopsy with MRI-TRUS fusion prostate biopsy in terms of cancer detection rates. PATIENTS AND METHODS: The data of the patients who had a Prostate Imaging Reporting and Data System (PI-RADS) score of 3 or more lesions on mpMRI and underwent MRI-TRUS fusion biopsy with simultaneous 12-core standard systematic biopsy from June 2016 to June 2019 in our tertiary center were retrospectively reviewed. Clinical, radiological and pathological data were recorded. Statistical difference among the groups was determined by using McNemar tests. RESULTS: A total of 344 patients were included in the study. As a result of transrectal targeted and systematic combined biopsy, 117 patients were diagnosed with prostate cancer. Benign pathology rates in patients with PI-RADS 3, PI-RADS 4, and PI-RADS 5 lesions were 93.8%, 68.5%, and 46.4%, respectively. Patients were divided into Iwo groups as ISUP grade 1 and ISUP grade >= 2 and cancer detection rates (CDRs) were found significantly higher in transrectal targeted biopsy compared with the systematic biopsy (12.5% vs. %6.4, p=0.007 and 17.4% vs. 8.7%, p
