甲状腺癌颈部淋巴结转移规律的超声诊断研究

摘要

目的：探讨超声对甲状腺癌颈部淋巴结转移规律的诊断价值。方法根据1991年美国头颈外科基金学院颈部淋巴结分组方法及2002年美国癌症联合委员会（AJCC）的Ⅶ区法对颈部可疑淋巴结进行分区，回顾性分析274例甲状腺癌颈部淋巴结转移的超声诊断符合率。结果超声对转移淋巴结的诊断符合率为82.8%，敏感度为57.8%，特异度为93.4%。超声诊断颈部Ⅱ、Ⅲ、Ⅳ、Ⅴ、Ⅵ区的敏感度及特异度分别为62.5%、98.3%；41.2%、96.4%；53.1%、95.1%；50.0%、97.2%和34.1%、89.7%。结论超声对甲状腺癌颈部淋巴结转移的诊断符合率较高，术前进行超声甲状腺癌颈部淋巴结分区对临床手术有一定的指导意义。%Objective To explore the diagnostic value of ultrasonography in thyroid cancer lymph node metastasis in the neck.Methods According to the American Institute of Head and Neck Surgery Foudation lymph node grouping method in 1991 and the American Joint Committee on cancer(AJCC)Ⅶ Zone Act in 2002, the zone action of suspicious lymph nodes in the neck were detected and the ultrasound diagnosis coincidence in thyroid cancer neck lymph node metastasis of 274 cases were analyzed.Results The ultrasound diagnosis coincidence of lymph node metastasis was 82.8%, the sensitivity was 57.8%and the speciifcity was 93.4%. The sensitivity and speciifcity of ultrasonography neckⅡ,Ⅲ,Ⅳ,Ⅴ,Ⅵ district were 62.5%, 98.3%; 41.2%, 96.4%; 53.1%, 95.1%; 50.0%, 97.2% and 34.1%, 89.7% respectively.Conclusions There is high ultrasound diagnosis coincidence of thyroid cancer neck lymph node metastasis and the preoperative ultrasoud thyroid cancer lymph node zone action provide the guidance for clinical surgery.
