ABSTRACT
Introduction: Evaluate the concordance of the TI-RADS classification and the Bethesda system to detect malignancy in patients with a thyroid nodule. Material and Methods: Through an observational, retrospective and cross-sectional study in 90 patients with a diagnosis of thyroid nodule, to which neck ultrasound was performed, definitive histopathological study and the TI-RADS (Thyroid Imaging Reporting and Data System) and Bethesda scales were applied during their approach from July 2018 to November 2020. Results: obtaining as a result, a predominance of the female sex, a sensitivity of 43.6% and specificity of 94.2% in classification of TI-RADS. Regarding the Bethesda classification, we obtained a sensitivity of 94.5% and a specificity of 51.4%. With a low agreement as a result between the two tests. Discussion: according to the results obtained in our study, we could verify that pa- tients with thyroid nodules benefit from an appropriate approach that includes a neck Doppler USG, performed by a trained professional, in addition to the realization of a Fine Needle Aspiration Biopsy (FNA) in the cases in which they are well indica- ted. The concordance test was low; therefore, we consider it necessary to use both diagnostic tests within clinical practice. Conclusion: the correct use of the TI-RADS classification to identify the characteristics of a thyroid nodule allows reliable diffe- rentiation to patients to undergo a FNA of those who do not require it. The Bethesda system can support decision making or change therapeutic behavior, especially in patients with high suspicion of malignancy.REFERENCES
