摘 要: | 目的:探讨甲状腺乳头状癌(PTC)与颈部淋巴结转移相关的超声征象,为判断PTC有无颈部淋巴结转移提供参考。方法回顾性分析2011-2013年哈尔滨医科大学附属第一医院经手术后病理证实的170例PTC患者的超声征象。其中59例伴颈部淋巴结转移,111例无颈部淋巴结转移。采用操作者工作特性(ROC)曲线分析阻力指数(RI)、收缩期峰值血流速度(PSV)判断PTC有无颈部淋巴结转移的最佳诊断界限值。采用χ2和秩和检验比较PTC伴颈部淋巴结转移患者与无颈部淋巴结转移患者原发灶超声征象差异。采用Logistic回归分析PTC伴颈部淋巴结转移的相关因素。结果 ROC曲线分析显示,RI、PSV判断PTC有无颈部淋巴结转移的最佳诊断界限值分别为0.735、13.95 cm/s。与PTC无颈部淋巴结转移患者比较,PTC伴颈部淋巴结转移患者原发灶直径、是否有晕环、是否累及甲状腺上极、有无微钙化、血供分级、RI及PSV差异均有统计学意义;而原发灶回声、边界是否清晰、纵横比差异均无统计学意义。多因素Logistic回归分析显示,PTC原发灶直径及PSV这2个因素是PTC伴颈部淋巴结转移的相关独立因素。结论 PTC原发灶的一些超声征象与PTC有无颈部淋巴结转移有密切的相关性,可为术前PTC患者颈部淋巴结有无转移的诊断提供有价值的信息。

Abstract: | Objective To study the sonographic features of papillary thyroid carcinoma (PTC) associated with cervical lymph nodes metastasis for early diagnosis and prediction of the invaded cervical lymph nodes. Methods The sonographic features of 170 patients with pathologically confirmed PTC in First Afifliated Hospital of Harbin Medical University between 2011 and 2013 were retrospectively reviewed. There were 59 cases with neck lymph nodes metastases and 111 cases without neck lymph nodes metastases. Receiver operating characteristic (ROC) curve was aaplied to analyze the cut-off values of resistance index (RI) and peak systolic velocity (PSV) for judging the presence or absence of cercical lymph node metastasis. The Chi-square test and rank sum test were used to compare the different sonographic features between each group. The Logistic regression analysis was used to obtain the relevant factors of PTCs with cervical lymph node metastasis. Results ROC curve analysis showed that the cut-off values of RI and PSV were 0.735,13.95 cm/s. The primary tumor diameter, the existence of halo, the involvement of thyroid upper pole, the microcalciifcation, the blood suply classiifcation and the RI, PSV were statistically signiifcantly different between PTCs with and without cervical lymph node metastasis, whereas no statistical signiifcance was detected between the primary tumor echo pattern, boundary and the longitudinal/transveral ratio between the metastatic and nonmetastatic group. Logistic regression analysis showed that the PTC primary tumor diameter and PSV were independent factors coorelated with cervical lymph node metastasis. Conclusion Some sonographic features of PTC are closely correlated with lymph nodes metastasis, which are valuable in predicting the cervical lymph nodes metastasis in patients with PTC pre-operatively. |
