目的:探讨甲状腺乳头状癌(papillary thyroid carcinoma,PTC)的灰阶超声特征与颈淋巴结转移的关系。方法:用灰阶超声评估162例病人的169个PTC结节,分为颈淋巴结未转移组和颈淋巴结转移组。灰阶超声主要评估甲状腺结节数目,癌结节的部位、大小、边界、边缘、边界与甲状腺被膜的关系、声晕、内部结构、回声水平、回声均匀性及钙化类型。将上述超声特征与颈淋巴结转移作单因素分析和多因素回归分析(Logistic回归),研究各超声特征与颈淋巴结转移的关系。结果:灰阶超声上,与颈淋巴结转移有关的超声特征主要有癌结节的大小、边界与甲状腺被膜的关系及癌结节内部的钙化类型,Logistic回归分析示癌结节的大小和内部钙化类型是颈淋巴结转移的相关因素。结论:特定的灰阶超声特征可一定程度提示PTC发生颈淋巴结转移的可能性,对外科手术方案的制定有一定的指导作用。
Objective: To investigate the relationship between gray scale ultrasound features and cervical lymph node metastasis of papillary thyroid carcinoma (PTC). Methods: 169 PTC nodules of 162 patients were evaluated by grayscale ultrasonography, and divided into cervical lymph node metastasis group and cervical lymph node metastasis group. Grayscale ultrasound mainly evaluates the number of thyroid nodules, the location, size, boundaries, margins, boundary of the nodules, the thyroid gland, the halo, the internal structure, the echo level, the echogenicity, and the type of calcification. The ultrasound features and cervical lymph node metastasis for univariate analysis and multivariate regression analysis (Logistic regression) to study the relationship between ultrasound features and cervical lymph node metastasis. Results: On gray scale ultrasound, the features of ultrasound related to cervical lymph node metastasis mainly include the size of cancer nodules, the relationship between the border and thyroid capsule and the type of calcification inside the cancer nodules. Logistic regression analysis showed the size of nodules and internal calcification Type is related to cervical lymph node metastasis. CONCLUSIONS: The specific gray scale ultrasound features may prompt the possibility of PTC cervical lymph node metastasis to some extent, which will guide the development of surgical plans.
