摘　　要：目的探讨术前甲状腺乳头状癌的超声检查特征与颈部淋巴结转移的关系。方法对我院2014年10月至2016年5月行甲状腺切除术及颈部淋巴结清扫的320例甲状腺乳头状癌患者的超声图像特征与颈部淋巴结转移进行多因素分析，评价其对颈部淋巴结转移的预测价值。结果多因素分析结果显示男性、结节直径〉1cm、存在微钙化、结节边缘不规则、多灶性结节，是甲状腺乳头状癌患者颈部淋巴结发生转移的危险因素（P〈0．05），TI—RADS与结节大小相结合ROC曲线下面积为0．792，预测甲状腺乳头状癌颈部淋巴结转移诊断效能较高。结论男性、结节直径〉1cm、存在微钙化、结节边缘不规则、多灶性结节是预测甲状腺乳头状癌发生颈部淋巴结转移的危险因素。Objective To explore the correlation between the ultrasonographic characteristics and cervical lymph node metastasis in papillary thyroid carcinoma （PTC）. Methods The clinical data of 320 PTC patients operated on from Oct 2014 to May 2016 were retrospectively reviewed. The correlation between age, sex, ultrasonographic characteristicsa and cervical lymph node metastasis was evaluated by multivariate analyses. Results Multivariate analysis showed that males, nodular size 〉 1 cm, microcalcification, irregular nodule margin, multifocality were risk factors for cervical lymph node metastasis. ROC curve analysis demonstrated important significance, which was drawn according to thyroid imaging reporting and data system （TI-RADS） and nodular size , with the area under ROC curve being 0.792. Conclusion Males, nodular size 〉 1 cm, microcalcification, irregular nodule margin, multifoeality are important indexes predicting cervical lymph node metastasis in patients with PTC.
