Objective: Thyroid fine-needle aspiration cytology is a dependable, effective method of detecting thyroid nodules. This study aims to assess the diagnostic distribution of thyroid fine-needle aspiration cytology, compare it to postoperative histological tissue diagnoses, and explore its diagnostic compatibility with published data.
Materials and Methods: This single-center retrospective descriptive study included 172 cases diagnosed histopathologically out of the 1675 thyroid fine-needle aspiration cytology procedures performed in the Bolu Abant İzzet Baysal University Fac-ulty of Medicine, Department of Medical Pathology, between 2014 and 2020. The study examined the correlation between cytological and histopathological diagnoses.
Results: Of the 172 cases, 132 were female (76.74%), and 40 were male (23.26%). The participants ranged in age from 14 to 79, with a mean age of 49.23±11.83. Fine-needle aspiration cytology results were compared to tissue diagnoses. The methods sensitivity was 61.29%, its specificity was 96.00%, its negative predictive value was 80.00%, its positive predictive value was 90.48%, and its diagnostic efficiency was 82.72%.
Conclusion: In our study, the sensitivity and specificity values of cytology were high. Fine-needle aspiration cytology had limited diagnostic contributions in diagnosing papillary microcarcinoma and follicular lesions. In addition to increasing cy-topathology experience to improve diagnostic compliance, we believe evaluating patients with clinical and radiological find-ings will better benefit patient treatment.
