However, magnetic resonance imaging (MRI) has the ability to enhance the diagnostic potential of TRUS biopsies. Our study aims to compare biopsy pathological grading of TRUS prostate systematic 12-core biopsy and MRI Fusion biopsy (MFB) to the final surgical pathology of radical prostatectomy specimens. METHODS: We examined a total of 221 patients who underwent MFB between October 2015 and August 2019. All patients underwent a double sextant 12-core biopsy along with biopsies of targeted lesions during the same procedure. A total of 126 patients underwent prostate biopsy for diagnostic indications, of which 42 went on to have a radical prostatectomy. Gleason scores from double sextant 12-core specimen were compared to those of regions of interest on MRI, and to the final pathology specimen where appropriate, as proxies for the TRUS and MFB approaches. Upgrading was defined as Gleason score 6 on biopsy, which showed a pathological score of 3+4 or above, while downgrading was the reverse. A chi-squared test was used to assess statistical significance. RESULTS: Median (IQR) age and PSA were 65 (60-69) years and 6.1 (4.4-9.0) ng/ml, respectively. A total of 76 patients had a positive biopsy result, of whom 42 underwent radical prostatectomy. Overall, PCa detection was higher in the MFB vs TRUS approach, albeit this finding was not statistically significant (48% vs 37%, p=0.06). Of the 42 patients that underwent surgery, 38 had a positive MFB compared to 27 in TRUS (90% vs 64%, p=0.004). The final pathological score coincided with TRUS and MFB 56% and 61% of the time (p=0.69), respectively. MFB had a higher rate of upgrading (13% vs 11%) and downgrading (33% vs 26%), but this was not statistically significant (p=0.66). CONCLUSIONS: Improved PCa detection by MFB approached statistical significance in patients undergoing a biopsy for diagnostic purposes. In those diagnosed with PCa, the detection rate with final pathology was superior in the MFB cohort. However, the discordance between MFB and final pathology questions its perceived superiority over TRUS, as both appear to be similarly accurate.
