前列腺癌临床诊断中经直肠彩超引导下穿刺诊断的敏感度及特异度

目的探讨前列腺癌(PCA)临床诊断中经直肠彩超引导下穿刺诊断的敏感度及特异度。方法选取103例临床疑似PCA的患者为研究对象,以手术病理结果为诊断金标准,对患者分别采用经直肠彩超通过直肠壁显示前列腺诊断(A方案)、经直肠彩超引导下穿刺活检诊断(B方案)。对2种诊断的敏感度、特异度和准确度进行统计学比较,分析2种诊断方法对PCA临床的判断价值。结果手术病理结果显示,103例患者中有60例(58.25%)诊断为PCA,其余43例(41.75%)为良性疾病。经直肠彩超通过直肠壁显示前列腺诊断结果显示,患者中有51例(49.51%)诊断为PCA,其余52例(50.49%)为良性疾病,与手术病理诊断结果比较,其诊断灵敏度、特异度、准确度分别为:73.33%(44/60)、83.72%(36/43)、77.67%(80/103);经直肠彩超引导下穿刺活检结果显示,患者中有56例(54.37%)诊断为PCA,其余47例(45.63%)为良性疾病,与手术病理诊断结果比较,其诊断灵敏度、特异度、准确度分别为:90.00%(54/60)、95.37%(41/43)、92.23%(95/103)。经直肠彩超引导下穿刺诊断效能均高于单纯的经直肠彩超诊断效能,差异有统计学意义(P<0.05)。结论经直肠彩超引导下穿刺诊断PCA优于单纯的经直肠彩超诊断,具有较高的临床应用价值。

Sensitivity and Specificity of Transrectal Color Doppler Ultrasound Guided Puncture for Prostate Cancer

Objective To investigate the sensitivity and specificity of transrectal ultrasound guided puncture in the clinical diagnosis of prostate PCA.Methods 103 patients with suspected clinical PCA were selected.Based on surgical and pathological findings,Transrectal color ultrasound was used to show prostate diagnosis(A scheme)and transrectal color ultrasound guided biopsy diagnosis(B scheme).The sensitivity,specificity and accuracy of the 2 diagnostic methods were statistically compared,analyze the value of 2 diagnostic methods in PCA clinical judgment.Results The pathological results showed 60(58.25%)cases of 103 patients were diagnosed as PCA,The remaining 43(41.75%)cases were benign,Transrectal color ultrasound showed prostate diagnosis through the rectal wall,Among the patients,51(49.51%)cases were diagnosed as PCA,patients The remaining 52(50.49%)cases were benign,Compared with the results of surgical and pathological diagnosis,Its diagnostic sensitivity,specificity and accuracy were 73.33%(44/60),83.72%(36/43)and 77.67%(80/103);Transrectal Color Doppler Guide Among the patients,56(54.37%)cases were diagnosed as benign diseases PCA,and the remaining 47(45.63%)cases were diagnosed as benign diseases.The diagnostic sensitivity,specificity and accuracy were 90.00%(54/60),95.37%(41/43)and 92.23%(95/103).The diagnostic efficiency of puncture guided by transrectal color Doppler ultrasound is higher than that of simple transrectal color Doppler ultrasound,the difference is statistically significant(P<0.05).Conclusion Transrectal color ultrasound guided puncture diagnosis PCA better than simple transrectal color ultrasound diagnosis,with a higher Clinical application value.
