Abstract:
Objective:To observe the size changes under ultrasound of 4C type thyroid micronodules classified by 2020 Chinese Thyroid Imaging Reporting and Data System (C-TIRADS)during follow-up.Methods:In this cross-sectional study, the data of thyroid ultrasonography in physical examination center in the Affiliated Zhongshan Hospital of Dalian University between December 2017 and December 2021 were retrospectively included, thyroid nodules were classified according to C-TIRADS, to observe the changes by ultrasound of maximum diameter and volume of 4C type thyroid micronodules during follow-up.Results:A total of 102 subjects receiving physical examinations with 103 thyroid micronodules were enrolled in this study. The maximum diameter and volume of thyroid micronodules at initial examination was 5.0 (4.0, 7.0) mm and 52.5 (25.2, 113.4) mm 3 respectively, and it was 6.0 (4.0,7.0) mm、65.6 (25.2,147.0) mm 3 at the last examination, respectively. Of the thyroid micronodules, 79 (76.7%) remained stable, 14 (13.6%) magnified and 10 (9.7%) shrunk during the follow-up. The cervical lymph nodes in all physical examiners were normal. There were significant changes in the maximum diameter and volume in the thyroid micronodules between the initial and last examination in subjects whose micronodules shrunk or magnified during the follow-up (all P<0.05). Conclusion:Size of most C-TIRADS 4C thyroid micronodules remains stable or even decreases during ultrasound follow-up observation, for such thyroid nodules, follow-up observation appears to be a safe and feasible way to postpone surgery.
