The Relationship Between American College of Radiology Thyroid Imaging Reporting and Data System (ACR TIRADS) and Fine Needle Aspiration Cytology (FNAC) ; in Geriatric Thyroid Pathologies.

Introduction: The world population is getting older with each passing year.Thyroid cancer is the most common endocrinological cancer and its incidence is increasing in all populations. Although the increase in prevalence has been attributed more to the increased use of imaging methods and to the higher sensitivity of ultrasonography (USG) by some authorities, there are also studies suggesting a real increase.In our study, it was aimed to examine the USG and fine needle aspiration cytology (FNAC) results of thyroid nodules in the geriatric age group and to discuss them in the light of the literature. Methods: Files of 129 geriatric patients with thyroid nodules detected in the University Of Health Sciences Adana City Training and Research Hospital between 2018 and 2020 were retrospectively analyzed.The USG characteristics of the patients were categorized by scoring according to the ACR TIRADS system. FNAC diagnoses were grouped according to the Bethesda classification. Results: According to the ACR TIRADS grading, 4 patients (3.1%) were benign, 58 patients (45%) were not suspicious, 38 patients (29.5%) were mildly suspicious, 25 patients (19.4%) were moderately suspicious, and 4 patients (3.1%) were highly suspicious.In our study, although USG provided very valuable information in the approach to thyroid nodules, no relationship was found between TIRADS in the geriatric age group and FNAC results in our study (p = 0.117). Conclusion: We think that the approach to thyroid nodules in geriatric patients requires closer follow-up not only with USG data but also with clinical and history-based findings.
