ABSTRACT

OBJECTIVE: To investigate the detection rate and complications of magnetic resonance imaging / transrectal ultrasonography (MRI/TRUS) cognitive fusion combined with 12-core systematic transperineal prostate biopsy (TPPB) in the diagnosis of clinically significant PCa (CS-PCa). METHODS: This retrospective study included 208 patients undergoing first-time MRI/TRUS cognitive fusion combined with 12-core systematic TPPB from June 2015 to May 2019. The patients, aged 54-85 (67.6 ± 7.8) years, all received digital rectal examination, PSA detection, TRUS and prostate multiparametric MRI (mpMRI) before biopsy. We analyzed the mpMRI images, identified and marked the suspected signal areas, repeated TRUS for further observation of the prostate, conducted cognitive fusion based on the mpMRI images and determined the target before 12-core systematic TPPB and subjecting the samples obtained to pathological examination. RESULTS: Of the 208 patients, 112 were diagnosed with CS-PCa (no case with tPSA < 4 µg/L, 21 cases with 4 µg/L ≤ tPSA < 10 µg/L, 47 cases with 10 µg/L ≤ tPSA < 20 µg/L, 40 cases with 20 µg/L ≤ tPSA < 100 µg/L, and 4 cases with tPSA ≥ 100 µg/L), 85 with BPH, 8 with chronic prostatitis, 2 with atypical prostatic hyperplasia, and 1 with prostatic intraepithelial neoplasia. Systemic inflammatory response syndrome occurred in 3 and gross hematuria and/or bloody stool in 12 cases after biopsy, which were all cured by anti-infection and hemostasis treatment. CONCLUSIONS: MRI/TRUS cognitive fusion combined with 12-core systematic transperineal prostate biopsy can improve the detection rate of the initial diagnosis of clinically significant PCa with a low incidence of controllable complications.
