【摘要】:目的探讨超声权重评分在甲状腺结节良恶性鉴别诊断中的应用价值。方法选取2012年3月—2015年4月北京大学人民医院进行超声检查的甲状腺结节患者125例为研究对象,记录结节低回声、边缘不规则、边界不清晰、晕环不均匀完整、实性结节、微钙化、纵横比(A/T)≥1 7项特征,根据各特征单独鉴别诊断甲状腺结节良恶性的特异度进行权重评分,7项相加得到超声权重评分。以病理检查结果为金标准,分为恶性和良性。绘制受试者工作特征曲线(ROC曲线)分析超声权重评分鉴别诊断甲状腺结节良恶性的价值。结果 125例患者共发现149个甲状腺结节,结节最大径0.3~7.0 cm,平均(2.1±1.2)cm。术后病理检查结果示:恶性52个,均为甲状腺乳头状癌;良性97个,其中结节性甲状腺肿86个,腺瘤9个,亚急性甲状腺炎2个。恶性甲状腺结节超声权重评分为(7.3±3.8)分,良性甲状腺结节超声权重评分为(1.8±2.4)分,差异有统计学意义(Z=-7.542,P0.001)。超声权重评分鉴别诊断甲状腺结节良恶性ROC曲线下面积为0.869〔95%CI(0.805,0.933)〕,最佳诊断截点为5.5分,诊断的灵敏度、特异度、正确率、阳性预测值、阴性预测值分别为69.2%、93.8%、85.2%、37.0%、98.3%。结论超声权重评分在鉴别诊断甲状腺结节良恶性方面有较高的应用价值。
