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 the differential diagnosis of benign and malignant thyroid nodules. Methods: 99 cases of thyroid nodules in our hospital from June 2014 to December 2015 were analyzed retrospectively. FNAC in thyroid nodules and postoperative histopathological results were compared. Tissue and pathology were taken as the gold standard to judge the diagnosis of benign and malignant thyroid gland Nodules sensitivity, specificity and coincidence rate, at the same time analyze the reasons for the discrepancy. Results: The sensitivity, specificity, and specificity of FNAC in diagnosing thyroid cancer were 80%, 95.7%, 88.9%, 2% respectively, false positive rate was 4.3% and coincidence rate was 90.9%. Conclusion: FNAC provides a reliable and valuable diagnostic basis for clinicians to decide on the operation, and also provides a scientific basis for patients to choose the appropriate treatment plan. It is worth to promote to other hospitals in our district.
