Analysis of pathological diagnosis by fine needle aspiration cytologyand paraffin in thyroid disease

Abstract

Objective To explore an economical and effective method for the diagnosis of thyroid diseases by fine needle aspiration cytology (FNAC). Methods The clinicopathological diagnosis of 1200 cases of thyroid diseases in our department was analyzed. Results There were 827 cases (68.9%) of thyroid carcinoma, 267 cases (22.2%) of thyroid adenoma, 66 cases (5.5%) of thyroid cyst, 31 cases (2.6%) of hyperthyroidism, and 9 cases (0.8%) of thyroiditis. FNAC cell diagnosis and postoperative paraffin standard comparison, benign lesions diagnosed percentage were 28.4% and 31.1% respectively, Diagnosis of malignant change percentage were 65.5% and 68.9% respectively, FNAC diagnosis of benign and malignant diagnosis efficiency cells percentage were 91.3% and 95.1% respectively, The specificity of the diagnosis of benign and malignant lesions compared percentage, there was no statistically significant difference (χ2=7.145, P>0.05). Conclusion FNAC method is reliable, convenient and economical in diagnosing thyroid diseases. It can also be used for preoperative diagnosis of thyroid surgery.
