摘　　要：目的:对比分析声触诊组织定量技术(VTTQ)和经直肠彩色多普勒超声(TRUS)对前列腺癌的诊断价值。方法:选取2016年1月至2017年9月本院急诊的前列腺疾病患者78例,根据经直肠穿刺前列腺活检结果分为前列腺增生组和前列腺癌组,分别为46例和32例;以同期进行体检的健康志愿者35例为对照组。所有研究对象均接受TRUS检查,同时应用VTTQ检测前列腺组织的剪切波速(SWV)。对比分析VTTQ和TRUS诊断前列腺癌的效能。结果:前列腺癌组和前列腺增生组SWV显著高于对照组(P<0.05),且前列腺癌组显著高于前列腺增生组(P<0.05);SWV=2.23m/s时,VTTQ诊断前列腺癌的敏感性、特异性、准确性分别为84.38%、86.96%、85.90%,TRUS诊断前列腺癌的敏感性、特异性、准确性分别为78.13%、65.22%、70.51%,VTTQ和TRUS诊断前列腺癌的敏感性比较差异无统计学意义(P>0.05),VTTQ诊断前列腺癌的特异性和准确性与TRUS比较差异有统计学意义(P<0.05)。结论:与TRUS相比,VTTQ对前列腺癌的诊断价值较好,具有较高诊断特异性和准确性。Objective:To analyze comparatively the diagnostic value of virtual touch tissue quantification(VTTQ)and transrectal ultrasonography(TRUS)in prostatic cancer.Methods:78 cases of patients with Prostate disease received from January 2016 to September 2017,according to the result of transrectal prostate biopsy,it was divided into prostate hyperplasia group 46 cases and prostate cancer group 32 cases.In the same period,35 healthy volunteers were included in the control group.All of them were examined by TRUS,at the same time,VTTQ was used to detect the shear wave velocity(SWV)of the prostate tissue,comparative analysis of the efficacy of VTTQ and TRUS in the diagnosis of prostate cancer.Results:The SWV in the prostate cancer group and the prostatic gland hyperplasia group and was significantly higher than that in the control group(P<0.05),the prostate cancer group was significantly higher than the prostatic gland hyperplasia group(P<0.05).When SWV=2.23m/s,the sensitivity,specificity and accuracy of VTTQ in the diagnosis of prostate cancer are 84.38%,86.96%,85.90%,the sensitivity,specificity and accuracy of TRUS in the diagnosis of prostate cancer are78.13%,65.22%,70.51%,there was no significant difference in the sensitivity of VTTQ and TRUS in the diagnosis of prostate cancer(P>0.05).The specificity and accuracy of VTTQ in the diagnosis of prostate cancer were significantly different from those in TRUS(P<0.05).Conclusion:Compared with TRUS,VTTQ has a better diagnostic value for the prostatic cancer,with higher diagnostic specificity and accuracy.
