Retrospective Comparison of Histopathologic Results of Thyroid Fine-Needle Aspiration Biopsies

Objective: To determine the utility of fine needle aspiration biopsy (FNAB) in the evaluation of thyroid lesions at our faculty by comparing the results of FNAB and pathology report results of the patients who underwent surgery.Methods: The study population consisted of 347 ultrasonography guided thyroid nodule biopsies. The cytological results were classified as benign, suspicious for malignancy, malignant and inadequate material.Results: Cytological results were reported as 347 (84.1%) benign nodules, 35 (3.8%) malignant suspicious nodules, 21 (2.3%) malignant nodules and 92 (9.9%) inadequate materials. 35 patients (20.6%) were male aged between 20-74 years old (45.0±6.2) and 135 patients (79.4%) were female aged between 15-85 (36.6±7.1) years old. Examined the results of resection, FNA of the success of a benign diagnosis (sensitivity), 75.9%, 31.3% in the success of follicular neoplasm., success in the diagnosis of malignancy was 14.3%.Conclusion: Fine needle aspiration biopsy is a functional and reliable diagnosing method. The use of US guidance is helpful to obtain adequate sample from nodules. Fine needle aspiration biopsy has become the gold standard to diagnose thyroid nodules.
