Fine-Needle Aspiration in Thyroid Nodules

FNA is a safe and simple method which can differentiate benign and malignant nodules in thyroid. In this retrospective study attempts were done to determine the accuracy of preoprative fine-needle aspiration biopsy (FNA). We compaired the FAN biopsies from 95 patients (70 female and 25 male) with their permenant pathology. They divided in two groups; in the first group, there were 64 (67%) patients with diagnostic report (50 benign and 14 Malignant), and the second group consist of 31 (33%) patient with suspicious report. In the first group, there were seven (19%) mistake in diagnosis with FNA, 3 false negative and 4 fase positive; and in the second group, there were six (19.4%) malignant and 25(80.6%) were benign. The sensitivity and the specificity of FNA in this study were 78% and 92% respectively. The positive predictive value was 73% and negative predictive value was 94%.
