【摘要】：目的对比分析颈部淋巴结转移(LNM)组与无LNM组甲状腺乳头状癌(PTC)超声特征的差异。方法对怀疑为甲状腺癌并拟行手术切除的患者进行常规超声检查及超声造影(CEUS)检查,记录患者年龄、性别及病灶超声特征。以手术病理结果为金标准,比较上述特征在LNM组与非LNM组之间的差异。结果共144例患者,其中51例伴颈部LNM,93例不伴LNM。年龄、性别、病灶数目在LNM组与非LNM组之间的差异无统计学意义(P0.05)。LNM组癌灶最大径大于0.85 cm,边界不清(P=0.000),形态不规则(P=0.007),内部回声不均匀(P=0.007),伴有微钙化(P=0.020),内部不均匀低增强(P=0.002),周边不规则无增强环(P=0.030)及包膜侵犯(P=0.000)。结论常规超声及CEUS特征可为预测PTC是否发生颈部LNM转移提供有效帮助,特别是CEUS对病灶包膜外侵犯的评估较准确,对LNM的预测有重要意义。
[Abstract]:Objective to compare and analyze the ultrasonographic characteristics of LNM in patients with cervical lymph node metastasis. Methods the patients suspected to be thyroid carcinoma with surgical resection were examined by conventional ultrasonography and contrast-enhanced echocardiography (CEUs). The age, sex and ultrasonic features of the lesions were recorded. The differences of the above characteristics between the LNM group and the non-#en1# group were compared by using surgical and pathological results as gold standard. Results 51 cases were associated with cervical LNM, 93 cases without LNM.Age and sex. There was no significant difference in the number of lesions between LNM group and non-#en1# group. There was no significant difference in the number of lesions between LNM group and non-#en1# group. The maximum diameter of cancer focus in LNM group was more than 0.85 cm, the boundary was not clear, the shape was irregular P0. 007, the internal echo was not homogeneous P0. 007, with microcalcification P0. 020, internal inhomogeneity and low enhancement P0. 002, peripheral heterogeneity. Conclusion conventional ultrasound and CEUS features can be used to predict cervical LNM metastasis in PTC. In particular, CEUS is more accurate in the evaluation of extracapsular invasion, and it is of great significance in predicting LNM.
