摘要 目的研究甲状腺乳头状微小癌(PTMC)颈部淋巴结转移(CLNM)患者术前超声的特征。方法回顾性分析2016年1月~2019年12月本院收治的经术后病理证实为PTMC的100例患者的临床资料,其中31例发生CLNM。所有患者术前均进行超声检查,对其术前超声检查资料进行分析,采用单因素分析对CLNM与非CLNM间术前超声图像特征的差异进行分析,采用多因素Logistic回归分析对CLNM的独立危险因素进行分析。结果单因素分析结果显示,两组癌灶位置、结节纵横比、结节形态、内部回声、回声内部成分比较,差异均无统计学意义(P>0.05);两组癌灶最大直径、结节边界清晰度、微钙化、内部血流信号、甲状腺包膜外侵犯超声特征比较,差异有统计学意义(P<0.05)。多因素Logistic回归分析结果显示,癌灶最大直径>5 mm、微钙化、甲状腺包膜外侵犯为CLNM独立的术前超声危险征象(P<0.05)。结论术前超声征象对于PTMC患者发生CLNM具有一定的预测价值,其中癌灶最大直径>5 mm、微钙化多、甲状腺包膜外侵犯为CLNM的高危特征。 Objective To study the characteristics of preoperative ultrasonography in patients with cervical lymph node metastasis(CLNM)of papillary thyroid carcinoma(PTMC).Methods From January 2016 to December 2019,the clinical data of 100 patients with PTMC confirmed by postoperative pathology in our hospital were analyzed retrospectively,31 patients developed CLNM among them.All patients underwent ultrasound examination before operation.The preoperative ultrasound examination data were analyzed.The difference between CLNM and non-CLNM preoperative ultrasound image characteristics was analyzed by univariate analysis,and the independent risk factors of CLNM were analyzed by multivariate Logistic regression.Results Univariate analysis showed that there were no significant difference between the two groups in the location,aspect ratio,shape,internal echo and internal echo components(P>0.05).There were significant differences between the two groups in maximum diameter of cancer focus,definition of nodal boundary,microcalcification,internal blood flow signal and extracapsular invasion of thyroid(P<0.05).The results of multivariate Logistic regression analysis showed that the maximum diameter of the cancerous foci>5 mm,microcalcification,and extrathyroidal invasion were independent preoperative ultrasound risk signs of CLNM(P<0.05).Conclusion Preoperative ultrasound signs have a certain predictive value for CLNM in patients with PTMC,among which the maximum diameter of the cancerous foci>5 mm,microcalcification and extrathecal thyroid invasion are the high-risk features of CLNM.
