ABSTRACT
OBJECTIVE: To investigate the application value of magnetic resonance-ultrasound fusion (MR-USF) guided transperineal prostate biopsy (TPPB) in the diagnosis of prostate cancer. METHODS: Relevant data were collected retrospectively from 77 patients undergoing MR-USF guided TPPB (n = 22) or 12-core systematic prostate biopsy (SPB) (n = 55) in Binhai People's Hospital from May to July 2019 and statistically analyzed using the software Graphad Prism 7.0 and SPSS 22.0. RESULTS: The patients were aged 51ï¼91 (70.5 ± 9.7) years, with a mean PSA level of (35.1 ± 115.4) µg/L (1.02ï¼959 µg/L) and an average prostate volume of (48.81 ± 38.4) cm3 (7.54ï¼307.61 cm3). There were no statistically significant differences in age, PSA, and BMI between the two groups of patients (P > 0.05). Prostate cancer was confirmed in 31 of the cases, with a positive rate of 40.26% (31/77), significantly higher in the TPPB (45.45% ï¼»10/22ï¼½ than in the SPB group (38.18% ï¼»21/55ï¼½, P < 0.01). Based on the PI-RADS scores, the Gleason grade was also higher in the former than in the latter group. CONCLUSIONS: MR-USF guided TPPB can improve the biopsy performance. Whether it should be used is based on the patient's PSA level and PI-RADS scores.
