目的对比MRI-经直肠超声(TRUS)软件融合导航穿刺与认知融合导航穿刺检出前列腺癌(PC)效果。方法回顾性分析120例疑诊PC患者、共127个病灶,均接受2~3针靶向穿刺(TB)+10针系统穿刺方案经会阴前列腺穿刺活检,并根据TB引导方法将其中73例(78个结节)接受MRI-TRUS软件融合导航穿刺归为A组,47例(49个结节)接受认知融合穿刺归为B组;比较2组经TB检出PC及临床显著性PC(csPC)阳性率、不同大小病灶PC阳性率,以及穿刺2针与3针PC阳性率。结果A组经TB检出PC阳性率及csPC阳性率分别为55.13%(43/78)及39.74%(31/78),B组分别为53.06%(26/49)及34.69%(17/49);组间差异均无统计学意义(P均>0.05)。对于最大径≤10 mm病灶,A组TB检出PC阳性率高于B组(P10 mm且0.05)。A组2针与3针TB检出PC阳性率差异无统计学意义(P>0.05),而B组3针TB检出PC阳性率高于2针(P<0.05)。结论MRI-TRUS软件融合导航穿刺检出PC及csPC阳性率与认知融合导航穿刺相当,但有助于减少TB次数、提高最大径≤10 mm小病灶检出率。
