Indication and Goal of Thyroid FNA

Thyroid nodular lesions are a common clinical problem. In the United States, 4 to 7% of the adult population have a palpable TN. The incidence of thyroid cancer in a clinically solitary TN or in a multinodular goiter is equal and about 5% in non-endemic areas. TNs constitute the main indication for FNA, and the goal of this diagnostic procedure is to detect thyroid neoplasms for surgical resection and to identify non-neoplastic lesions that may be managed conservatively. This method of clinical investigation has reduced the number of diagnostic thyroid surgeries for TNs by 60–85%, and the difference in rates of thyroid surgery reflect the cytodiagnostic accuracy rates among different medical centers.
