摘要
目的探讨甲状腺结节超声恶性危险分层中国指南(C-TIRADS)和美国甲状腺协会(ATA)指南对甲状腺乳头状癌(PTC)的诊断价值。资料与方法回顾性收集2019年7月—2021年5月联勤保障部队第九〇九医院甲状腺结节术后且有明确病理结果的259例患者(339个结节),分为甲状腺良性结节组150例(210个结节)和PTC组109例(129个结节),分析两组一般资料和结节声像图特征,分别用两种指南对结节进行分类并与手术病理结果进行对照,绘制受试者工作特征曲线评价两种指南对PTC的诊断价值。结果两组恶性声像图特征中,实性、边缘模糊/不规则或甲状腺外侵犯、垂直位、低或极低回声、微钙化差异有统计学意义(χ^(2)=123.67、132.71、103.82、4.58、137.93,P均<0.05),以PTC组多见;与C-TIRADS不同,ATA指南对61个结节(61/339,17.99%)分类不明确;C-TIRADS和ATA指南的曲线下面积分别为0.952(0.924~0.972)、0.942(0.911~0.964),差异无统计学意义(Z=0.943,P=0.346);两者的最佳截断值为4b类和高度可疑,C-TIRADS的敏感度最高[0.930(120/129)比0.822(106/129)],ATA指南的特异度最高[0.857(180/210)比0.943(198/210)],差异均有统计学意义(χ^(2)=6.99、8.57,P均<0.01),两组准确度[0.885(300/339)比0.897(300/339)]差异无统计学意义(χ^(2)=0.24,P=0.622)。结论C-TIRADS和ATA指南对PTC均有很高的诊断效能,但C-TIRADS适用于所有甲状腺结节的声像图表现,且受超声医师临床经验影响小,更易在临床推广使用。
Purpose To evaluate the diagnostic value of Chinese thyroid imaging reporting and data system(C-TIRADS)and American thyroid association(ATA)guidelines in papillary thyroid carcinoma(PTC).Materials and Methods A total of 259 patients(339 nodules)with definite pathological results after thyroid nodule surgery in the 909th Hospital of the Joint Logistic Support Force(the Affiliated Southeast Hospital of Xiamen University)from July 2019 to May 2021 were divided into benign thyroid nodule group(150 cases,210 nodules)and PTC group(109 cases,129 nodules).General data and nodule ultrasonographic characteristics of the two groups were retrospectively analyzed.Nodules were classified by the two guidelines,and were compared with surgical pathological results,the receiver operating characteristic curve was drawn to evaluate the diagnostic value of the two guidelines for PTC.Results There were statistically significant differences between the two groups in the malignant ultrasonographic features of"solid,blurred/irregular edges or extrathyroid invasion,verticality,low or very low echo,microcalcification"(χ^(2)=123.67,132.71,103.82,4.58,137.93,all P<0.05),and most commonly seen in the PTC group.Unlike C-TIRADS,61 nodules were not clearly classified in the ATA guidelines,accounting for 17.99%(61/339).The areas under the curves of C-TIRADS and ATA guidelines were 0.952(0.924-0.972)and 0.942(0.911-0.964),with no statistically significant differences(Z=0.943,P=0.346).The optimal cutoff values of the two groups were 4b and highly suspicious malignancy,and the sensitivity,specificity and accuracy were 0.930(120/129)vs.0.822(106/129),0.857(180/210)vs.0.943(198/210),0.885(300/339)vs.0.897(300/339),respectively.There were significant differences in sensitivity and specificity(c2=6.99,8.57,both P<0.01),C-TIRADS had the highest sensitivity,ATA guidelines had the highest specificity,but there was no significant difference in accuracy(c2=0.24,P=0.622).Conclusion Both C-TIRADS and ATA guidelines may be highly effective in the diagnosis of
