Introduction: The incidence of thyroid nodules is increasing. Fine-needle aspiration (FNA) of all thyroid nodules is unnecessary, but it is necessary to provide a more precise identification of those nodules that are potentially malignant in nature. In the literature there are several suggested systems for assessing malignancy of nodules in the thyroid gland.
Objective: To determine the differences between EU and ACR TIRADS recommendation for fine-needle aspiration in patients with thyroid nodules in our center.
Methods and material: The study involved 127 patients, with 132 nodes referring to FNA. An ultrasound examination was performed before the FNA, and according to its ultrasonic properties, the nodes was classified according to the EU and ACR TI-RADS classification. After the cytopathological result was obtained, differences in FNA indications, which were determined according to these two classifications, were analyzed.
Results: The analysis found that there is a statistically significant difference in relation to the classification of a node in certain TI-RADS categories when compared to the EU and ACR system (χ2=11.105, P=0.0254). In 23.5% of the nodules, a different category was obtained. FNA was indicated in 76.5% of nodules according to ACR TI-RADS criteria, and in 81.8% of nodules according to EU TI-RADS criteria. In one case, FNA was indicated only according to EU TI-RADS, and the cytopathological finding corresponded to the Bethesda IV category. In other cases, when the indication for FNA was different, the cytopathological finding indicated a benign nodule.
Conclusion: The EU and ACR TI-RADS is a useful tool in assessing malignancy of thyroid nodules. If EU TI-RADS is used, FNA is indicated in a slightly larger number of cases.
