Abstract：Objective To study the clinical value of fine-needle aspiration cytology of thyroid nodule. Methods A retrospective review was performed among 578 consecutive cases of FNA cytology of thyroid nod-ules. Cytologic diagnoses were classified as non-diagnostic or unsatisfactory, benign, atypia of unknown signifi-cance/follicular lesion of unknown significance( AUS/FLUS) , suspicious for follicular neoplasm( SFN) , suspi-cious for malignancy and malignancy based on the Bethesda system. The discrepancies between initial cytologic diagnoses and histologic diagnoses were evaluated among 132 surgical specimens. Results Among 132 cases who underwent surgery, FNAs were 7. 6% unsatisfactory, 43. 2% benign,19. 7% AUS/FLUS, 5. 3% SFN, 6. 8% suspicious, and 17. 4% malignant. The sensitivity, specificity and positive predictive value of thyroid FNA for the diagnosis of malignancy were 81. 1%,97. 6%and 93. 8%respectively. Conclusions Fine-needle aspiration is a reliable method for identifying benign and malignant thyroid nodules.
