Özet

Aimː To evaluate data from our hospital system before and after the implementation of the BethesdaSystem for Reporting Thyroid Cytology (TBSRTC) and comparison of our data with the previouslypublished studies.Methods: Seven hundred seventy-one patients with thyroid nodules who underwent fine needleaspiration biopsy (FNAB) and surgery at our institution were analyzed retrospectively. FNABresults were divided into two parts in terms of the period they related to: pre-TBSRTC (between 2005and 2010) and TBSRTC (between 2011 and 2013).Results: 341 FNAB were applied in the period of TBSRTC. Of the 341 FNAB, 53(16%) were nondiagnostic, 82(24%) were benign, 62(18%) were atypia of undetermined significance or follicularlesion of undetermined significance (AUS/FLUS), 28(8%) were follicular neoplasms and/orsuspicion of follicular neoplasms (FN/SFN), 95(28%) were suspicion for malignancy (SuspM), and21(6%) were malignant. Rates of malignancy reported on follow-up histopathological examinationwere non diagnostic in 11%, benign in 4.9%, AUS/FLUS in 23%, FN/SFN in 32%, SuspM in 44%,and malignant in 95.3%.Conclusions: In this study, the distribution of cases in TBSRTC categories and malignancy rates,differed from, recommended by TBSRTC and some studies. Implementation of TBSRTC didsignificantly affect our institution’s reporting rates.
