摘要:

目的 基于剪切波弹性成像联合二维超声建立预测模型,探讨其对甲状腺乳头状癌中央区 淋巴结转移的预测价值。方法 选取 501 例甲状腺乳头状癌(PTC)患者,回顾性分析结节的二维声像图 特征及剪切波弹性成像,以术后病理为金标准,将患者分为中央区淋巴结转移组和非转移组。采用受试 者工作特性(ROC)曲线分析剪切波弹性测值判断有无中央区淋巴结转移的最佳截断界值。采用单因素 和多因素回归分析影响中央区淋巴结转移的独立危险因素,建立预测模型。建立模型后,纳入 131 个甲状 腺乳头状癌结节进行验证,与术后病理比较,评价预测能力。结果 logistic 回归分析显示最终纳入影响 中央区淋巴结转移的因素为肿瘤大小、多灶性、包膜浸润及 Emean 值。将多因素 logistic 回归得出的预测 概率值绘制 ROC 曲线,其 ROC 曲线下面积(AUC)为 0.908。应用验证组进行验证,其准确性为 93.1%,敏 感度为 90.5%,漏诊率为 9.5%,特异度为 93.2%,误诊率为 6.8%。结论 基于剪切波弹性成像联合二维超 声构建预测模型,对 PTC 中央区淋巴结转移有较好的预测价值,有助于提高 PTC 颈部淋巴结转移的术前 诊断率,可在一定程度上为临床治疗方案的选择提供帮助

Abstract:

Objective To establish a predictive model based on shear wave elastography combined with two ⁃dimensional ultrasound,and to explore its predictive value for central lymph node metastasis in papillary thyroid carcinoma(PTC). Methods A total of 501 patients with PTC were selected,and the two ⁃dimensional sonographic features and shear wave elastography of the nodules were retrospectively analyzed. Using postoperative pathology as the gold standard ,the patients were divided into central lymph node metastasis group and non⁃ metastatic group. The receiver operating characteristic(ROC)curve was used to analyze the shear wave elasticity measurement to determine the best cut⁃off value for the central lymph node metastasis. Single⁃factor and multi⁃ factor analysis of independent risk factors affecting central lymph node metastasis were used to establish a predictive model. After the model was established,131 papillary thyroid carcinoma nodules were included for verification to evaluate the predictive ability,compared with postoperative pathology. Results Logistic regression analysis showed that the factors that affected the central lymph node metastasis were tumor size,multifocality,capsular infiltration,and Emean value. The ROC curve with the predicted probability value was drawn,and the area under curve of the ROC was 0.908.The verification group was used to verify that the accuracy was 93.1%,the sensitivity was 90.5%,the missed diagnosis rate was 9.5%,the specificity was 93.2%,and the misdiagnosis rate was 6.8%. Conclusion The prediction model based on shear wave elastography combined with two ⁃dimensional ultrasound has a good predictive value for lymph node metastasis in the central area of papillary thyroid carcinoma,which helps to improve the preoperative diagnosis rate of central lymph node metastasis in PTC. To a certain extent,it provides help for the choice of clinical treatment plan.
