The KWAK TI-RADS and 2015 ATA guidelines for medullary thyroid carcinoma and Papillary Thyroid Carcinoma: combined with cell block assisted ultrasound guided thyroid fine needle aspiration

The operative pathology results showed that 29 patients had MTC (male:female, 11:18), 31 patients had PTC (male:female, 5:26), and 33 patients had TA (male:female, 4:29) . The mean patient ages in the MTC, PTC, and TA groups were 55.21±2.95, 43.84±2.33, and 53.67±2.42 years, respectively. The mean sizes of the MTCs, PTCs, and TAs were 1.72±0.18, 1.05±0.09, and 1.88±0.2 cm, respectively. No study has compared the diagnosis of MTC and PTC using the KWAK TI-RADS and 2015 ATA guidelines, and combined CB and ultrasound guided FNA in MTC. Therefore, the purpose of this study was to evaluate the applicability of the TI-RADS and 2015 ATA guidelines to patients with MTC and PTC, and to find the role of CB assisted FNA in MTC.
