目的：探讨超声引导下颈淋巴结穿刺活检对甲状腺癌治疗的临床指导价值。方法回顾性分析80例甲状腺癌伴有颈淋巴结异常患者超声引导下颈淋巴结穿刺活检结果，并与术后病理诊断结果进行比较。结果超声引导下颈淋巴结穿刺对于甲状腺癌转移情况整体准确率为91．8％。按照病理类型分类，该方法对于髓样癌及未分化癌准确率最高（100％），各分型患者诊断率差异有统计学意义；按照肿瘤分期分类，该方法对于T1、T2、T3及T4期患者诊断准确率分别为73．3％、90．0％、85．2％及85．7％，T2～T4期患者诊断率均显著高于T1期患者。全部患者均未发生严重并发症。结论超声引导下颈淋巴结穿刺活检对甲状腺癌诊断有较高的临床应用价值，对甲状腺癌治疗的开展具有重要的指导意义。%Objective To explore the clinical value of ultrasonography guided needle biopsy of cervical lymph node in the diagnosis of thyroid cancer .Methods 80 thyroid cancer patients with abnormal cervical lymph node who underwent ultra-sonography guided needle biopsy were retrospectively analyzed ,and compared with postoperative pathological result .Results The total diagnostic accuracy of ultrasonography guided needle biopsy of cervical lymph node was 91.8%.The accuracy of different pathological types had statistically difference , and the accuracy of of medullary carcinoma and undifferentiated carcinoma were 100%.The accuracy of patients in T1,T2,T3 and T4 were respectively 73.3%,90.0%,85.2%and 85.7%,and the accuracy of T2~T4 was obviously higher than T 1.All patients had no serious complications .Conclusion Ultrasonography guided needle bi-opsy of cervical lymph node has clinical value in the diagnosis of thyroid cancer ,and it is conducive to the treatment of thyroid cancer .
