Monique Freire Santana, Luiz Carlos De Lima Ferreira

Abstract :

The objective of this study was to describe the accuracy of the thyroid FNA and a and cyto–histologic correlation. This is a retrospective review, of diagnostic accuracy, using the reports of FNA samples and histopathology from surgical specimens obtained from thyroidectomies as a gold standard. 3,811 cytological reports from 3,364 patients were analyzed. The median age 51 ± 13.3 years (18–99) and male to female ratio 1:15.5 (female: n=3.581, 94%, median age 51) (male: n=230, 6%, 6%, median age 52.2). In 1,721 satisfactory smears, 1,359 (35.7%) were benign, 30 (0.8%) atypical/follicular lesions of undetermined significance, 182 (4.8%) follicular neoplasm/suspicious for follicular neoplasm, 92 (2.4%) suspicious for malignancy and 58 (1.5%) were malignant, with malignancy rates of 16%, 11%, 25%, 23%, 58% and 88%, respectively. The accuracy FNA was 66.2% with 68.2% sensitivity and 63.9% specificity. This study is the biggest describe analysis of thyroid FNA samples performed in Brazil. Our accuracy was similar to other prospective studies and meta–analysis.
