摘　　要：目的应用超声观察中国甲状腺影像报告和数据系统(C-TIRADS)4C类甲状腺微小结节随诊期间的大小变化。方法本研究为横断面研究,回顾性分析2017年12月至2021年12月大连大学附属中山医院体检中心的甲状腺超声检查资料,根据C-TIRADS分级标准对结节进行分类,应用超声观察4C类甲状腺微小结节随诊期间最大直径与体积的变化。结果共有102例体检者103个甲状腺微小结节纳入本研究。甲状腺微小结节初次检查最大直径与体积分别为5.0(4.0,7.0)mm、52.5(25.2,113.4)mm^(3),末次检查最大直径与体积分别为6.0(4.0,7.0)mm、65.6(25.2,147.0)mm^(3)。随诊期间79(76.7%)个甲状腺微小结节保持稳定,14(13.6%)个结节增大,10(9.7%)个结节减小,所有体检者未发现颈部淋巴结异常。结节增大组和缩小组中甲状腺微小结节末次检查的最大直径、体积与初次检查比较差异均有统计学意义(均P<0.05)。结论超声观察期间大部分C-TIRADS 4C类甲状腺微小结节的大小保持稳定甚至减小,对该类结节进行随诊观察暂缓手术治疗是安全可行的。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.
