Diagnostic value of fine needle aspiration cytology in lymph node metastasis of nasopharyngeal carcinoma

目的探讨细针吸取细胞学检查在鼻咽癌淋巴结转移中的诊断价值。方法对浅表可疑淋巴结行细针吸取细胞学检查并与纤维鼻咽镜病理活检对照分析。结果细胞学诊断为鼻咽癌淋巴结转移101例,与病理活检诊断符合率98%(99/101),假阴性3例,假阳性2例。结论细针吸取细胞学对确诊鼻咽癌淋巴结转移,尤其是原发灶隐匿、无鼻咽部症状的病例具有较高价值。

Objective To investigate the diagnostic value of fine needle aspiration cytology （FNAC） in lymph node metastasis of nasopharyngeal carcinoma. Methods FNAC was performed in fleet-lymph nodes, then we contradistinguished the cytology diagnosis and histological diagnosis. Results 101 cases were diagnosed as lymph node metastasis of nasopharyngeal carcinoma by cytology, comparied with histologic diagnosis, the diagnostic accuray of cytology was 98%（99/101）, 3 eases were false negative, 2 cases were falsepositive. Conclusions FNAC is of great value to confirm the diagnosis of lymph nodes metastasis of nasopharyngeal carcinoma, especially, for the patients with lymph nodes metastasis without nasopharyngeal symptom.
