对比MRI-经直肠超声软件融合导航穿刺与认知融合导航穿刺检出前列腺癌效果

Comparison on efficacy of MRI-transrectal ultrasound software fusion-guided biopsy and cognitive fusion-guided biopsy for detecting prostate cancer

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(P<0.05);而对于最大径>10 mm且<15 mm、≥15 mm病灶,组间TB检出PC阳性率差异均无统计学意义(P均>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。

Objective To compare the efficacy of MRI-transrectal ultrasound(TRUS)software fusion-guided biopsy and cognitive fusion-guided biopsy for detecting prostate cancer(PC).Methods Data of 120 patients with suspected PC(127 lesions)who underwent transperineal prostate biopsy with 2—3 times of target biopsy(TB)and 10 times of system biopsy were retrospectively analyzed.According to TB guidance methods,73 cases(78 lesions)received MRI-TRUS software fusion-guided biopsy were classified into group A,and 47 cases(49 lesions)received cognitive fusion-guided biopsy were classified into group B.The positive rate of PC,clinic significant PC(csPC)and PC in different sized lesions by TB were compared between groups,and the positive rate of PC between 2 or 3 times TB was also compared within each group.Results The positive rate of PC and csPC detected by TB was 55.13%(43/78)and 39.74%(31/78)in group A,53.06%(26/49)and 34.69%(17/49)in group B,respectively,no significant difference was found(all P>0.05).The positive rate of PC in lesions with the maximum diameter≤10 mm detected by TB in group A was higher than that in group B(P<0.05),but no significant difference of lesions with the maximum diameter>10 mm and<15 mm nor≥15 mm was found between groups(all P>0.05).No significant difference of positive rate of PC was found between 2 and 3 times TB in group A(P>0.05),while positive rate of PC of 3 times TB was significantly higher than that of 2 times TB in group B(P<0.05).Conclusion MRI-TRUS software fusion-guided biopsy had positive rate of PC and csPC similar to that of cognitive fusion-guided biopsy,but was helpful for reducing times of TB and increasing detecting rate for lesions with the maximum diameter≤10 mm.
