Fine-needle aspiration for the diagnosis of lymph node metastasis in papillary thyroid carcinoma



Fine-needle aspiration for the diagnosis of lymph node metastasis in papillary thyroid carcinoma



Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi 54(1): 23-27



目的: 评价超声引导下细针穿刺技术(fine-needle aspiration,FNA)在诊断甲状腺乳头状癌侧颈淋巴转移的预测价值。 方法: 回顾性分析85例甲状腺乳头状癌患者的109枚超声怀疑转移的侧颈淋巴结,行细针穿刺细胞学检查(fine needle aspiration cytology,FNAC),细针穿刺甲状腺球蛋白检测(fine needle aspiration thyroglobulin,FNATg),细针穿刺甲状腺球蛋白/外周血甲状腺球蛋白检测(FNATg/SerumTg),以手术病理诊断作为淋巴转移的金标准,判断侧颈淋巴结细针穿刺的诊断价值。用非参数检验,Pearson线性模型及受试者工作特征曲线对研究结果进行分析。 结果: FNATg和FNATg/SerumTg在诊断甲状腺癌侧颈淋巴转移的灵敏度、特异度和准确率分别为93.7%、90.0%,93.3%和89.9%、90.0%和93.2%,其预测淋巴转移的临界值分别为0.925 ng/ml和1.007,FNATg联合FNAC诊断的灵敏度、特异度和准确率分别为91.0%、93.5%和94.4%;甲状腺组织和外周血Tg对侧颈淋巴结FNATg的检测结果无明显影响,在患者有甲状腺组织的情况下采用淋巴结FNATg的诊断准确性最高(临界值0.925 ng/ml),在患者无甲状腺组织的情况下采用FNATg/SerumTg的诊断准确性最高(临界值14.95);外周血中甲状腺球蛋白抗体(TgAb)的存在显著影响了有甲状腺癌转移淋巴结FNATg的表达水平(P=0.049)。 结论: 侧颈淋巴结FNATg检测或联合FNAC检测可有效监测甲状腺乳头状癌的侧颈淋巴转移,外周血TgAb的存在影响了FNATg用于预测甲状腺乳头状癌侧颈淋巴转移的准确性。.
