目的: 评价细针穿刺细胞学检查( Fine needle aspiration cytology，FNAC) 在良恶性甲状腺结节鉴别诊
断中的价值。方法: 分析99 例2014－06～ 2015－12 就诊我院的甲状腺结节病人的相关资料，对比甲状腺结节病
人FNAC 与手术后组织病理结果，以组织病理为金标准，判断FNAC 诊断良恶性甲状腺结节的敏感性、特异性及
符合率，同时分析差异不一致的原因。结果: FNAC 诊断甲状腺癌的敏感性为80%，特异性为95．7%，阳性预测值
为88．9%，假阴性率为2%，假阳性率为4．3%，符合率为90．9%。结论: FNAC 为临床医师是否决定手术提供可靠
的、有价值的诊断依据，也为病人选择恰当的治疗方案提供科学依据，值得向我区内其他医院推广。

Objective: To evaluate the value of fine needle aspiration cytology( FNAC) in benign
and malignant thyroid nodules during diagnosis．Methods: Analyzing relevant information of patients
with thyroid nodules from 99 cases in our hospital from June 2014 to December 2015．Comparing patients
with thyroid nodules FNAC and histopathology results after surgery， setting histopathology as the
gold standard to judge the sensitivity， specificity and coincidence of FNAC diagnosis of benign and malignant
thyroid nodules，and analyzing the reasons for the inconsistent differences． Results: The
sensitivity of FNAC diagnosis of thyroid cancer was 80%，specificity was 95．7%，positive predictive
value was 88．9%， the false negative rate was 2%， the false positive rate was 4．3%，and the coincidence
was 90．9%． Conclusion: The FNAC not only provides reliable and valuable diagnostic basis for
clinicians to decide whether to conduct surgery，but also supplies a scientific basis for patients to choose
the right treatment program．It is worthy to be popularized to other hospitals in our province．
