Cognitive Versus Magnetic Resonance-Ultrasound Fusion Prostate Biopsy: Which One Is Worthier to Perform?

Abstract

The aim of our study is to compare 2 prostate fusion biopsy models in terms of accurate target sampling. One hundred patients who had Prostate Imaging-Reporting and Data System score 3, 4, or 5 lesions (lesion diameter, >5 mm in long axis) in multiparametric-magnetic resonance imaging and prostate-specific antigen levels between 3 and 10 ng/mL were enrolled in the study. All patients were biopsy naive. Two groups were composed with 50 patients each. Group 1 patients had cognitive fusion (CF) biopsy, and group 2 had magnetic resonance-ultrasound fusion platform biopsy. After fusion biopsy, standard biopsy was also performed. Outcomes of histopathologic and demographic data were evaluated statistically. There were no statistical differences between the 2 groups in terms of age, prostate-specific antigen levels, prostate volume, and lesion length (P > 0.05). There was no statistically significant difference in sampling targeted lesions (P > 0.05). Also, no difference was found between the 2 groups in terms of random biopsy cancer detection rates (P > 0.05). There was no statistically significant difference between CF and magnetic resonance-ultrasound fusion in terms of cancer detection rates. For the experienced operators, we recommend lesions that are longer than 5 mm can be sampled using CF, an inexpensive and faster technique.
