FNAC在甲状腺癌术前诊断中的应用价值

Evluation of Preoperation FNAC in Diagnosis of Thyroid Gland Cancer

目的:对甲状腺癌术前FNAC诊断进行评价。方法:采用细针吸取涂片、HE,Wright染色诊断甲状腺癌,将术前FNAC结合与术后组织切片诊断进行对比分析。结果:甲状腺FNAC检查5776例,其中判断为甲状腺癌193例。有术后组织切片诊断对照113例,两者完全符合和基本符合占87.6％,不符合占12.4％。FNAC诊断甲状腺癌的敏感性为91.7％,阳性预测值为98％,假阳性为2.7％。结论:术前FNAC诊断甲状腺癌敏感性高,可直接为临床外科术前治疗提供细胞病理学依据,应予推广。

Objective: To evaluate the accuracy of Preoperative fine needle aspiration Cytology (FNAC)in the diagnosis of thyroid Carcinoma.Methods:The 113 Cases of thyroid Carcinoma that was diagnosed by FNAC and confirmed by surgical histology were retrospectively analysed. Results:The total correspondence rate was 87.6％, the sensitivity of FNAC in diagnosing thyroid carcinoma was 91.7％.The positive prospective rate of FNAC of the thyroid tumor was 98％ .Only 2.7％ of these cases had afalse-positive cytology. Conclusions:The sensitivity of FNAC in diagnosing thyroid carcinoma was found to be high (91.7％).It is becoming a widely accepted and utilized method in the preoperative assessment of palpable thyroid lesions.
