lower than that by targeted combined system biopsy,but the difference was not statistically significant(P=0.05). If only targeted biopsy
was performed,5.0% of CsPCa would be missed. In patients with a PI⁃RADS score of 4,the detection rate of CsPCa by targeted biopsy
was lower than that by targeted combined system biopsy,the difference was statistically significant(P<0.05). If only targeted biopsy
was performed,6.2% of CsPCa would be missed. When 0<PSA ≤20 ng/mL,the detection rate of CsPCa by targeted biopsy was lower
than that by targeted combined system biopsy,the difference was statistically significant(P<0.05);but when 20 ng/mL<PSA≤50 ng/mL,
the difference was not statistically significant(P>0.05). In patients with a PI⁃RADS score of 5,the detection rate of CsPCa by targeted
biopsy was lower than that by targeted combined system biopsy,while the difference was not statistically significant(P>0.05). If only
targeted biopsy was performed,3.5% of CsPCa would be missed. In PSA subgroup analysis,there was also no significant difference in
the detection rate of CsPCa between the two methods(P>0.05). The coincidence rate between targeted biopsy and radical
postoperative pathology was slightly lower than that of targeted combined system biopsy group,but the difference was not statistically
significant(P>0.05). In PI⁃RADS score subgroup and PSA stratification analysis,there were also no significant difference in the
coincidence rate between targeted biopsy and targeted combined system biopsy(P>0.05). Conclusion:For patients with suspected
high⁃risk prostate cancer with a PI⁃RADS score of 4⁃5,when PI⁃RADS score is 4 and PSA > 20 ng/mL or PI⁃RADS score is 5,a single
targeted biopsy may replace the targeted combined system biopsy.
