Abstract:

Purpose: This study is aimed at conducting a cutting-edge examination by comparing the results of thyroid thin injection aspiration biopsy (TIAB) with the results of the histopathology report and assessing the effectiveness of the TIAB in the thyroid nodes. Tools and Methods: TIIAB data of 75 patients applied thyroidectomy in the 2.5 year period between January 2016 and June 2018 at the University of Kırıkkale Medical School Hospital and histopathology report results formed the material of our study. TIIAB results were classified as benign, uncertain atypical or follicular damage (AUS/FLUS), suspected damage for follicular neoplasm or follicular neoplasm (FN/SFN), suspicious for malignity (SuspM), malign and insufficient for diagnosis (NDS). Results: TIIAB results of cases applied for thyroidectomy surgery were evaluated and 26 of these cases were diagnosed as benign (34.7 percent), 3 percent (4 percent) AUS/FLUS, 6 percent (8 percent) FN/SFN, 18 percent (24 percent) SuspM, 7 percent (9.3 percent) malign and 15 percent (20 percent) NDS. 4 of the phenomena assessed as benign, 2 of the phenomena assessed as AUS/FLUS, 15 of the phenomena assessed as SuspM and 7 of the phenomena assessed as malign were all malign in terms of tissue diagnosis. Our study calculated sensitivity, specificity, positive predictive values and negative predictive values as 74.2, 91.7, 92% and 73.3% respectively. Result: When the findings were evaluated together, it was concluded that the TIIAB technique is an effective and easy-to-apply method in the approach to the thyroid nodes. Today it is believed that it has a great importance in the assessment of TIIAB materials and is widely used, with the "Bethesda System for the Reporting of Thyroid Cytopathology" standardization in TIIAB diagnoses is provided.
