| 【】目的 研究甲状腺微小乳头状癌(PTMC)患者超声灰阶声像图特征与颈部淋巴结转移(LNM)的关系,分析超声灰阶声像图特征对PTMC患者颈部LNM的预测价值。方法 临床纳入2016年5月至2018年5月期间我院收治的83例PTMC患者作为研究对象,所有研究对象均进行超声灰阶声像图检查,分析超声灰阶声像图特征,与颈部LNM做回归分析,观察两者之间的关系。结果 PTMC患者超声灰阶声像图特征中性别、年龄、病灶直径、部位、纵横比、内部钙化类型、与被膜的关系以及微钙化会否超出结节均与颈部LNM有关,P＜0.05；而超声灰阶声像图特征中的边缘和内部回声与颈部LNM无关,P＞0.05。多因素回归分析发现,性别、年龄、病灶直径、部位、纵横比、内部钙化类型以及微钙化是否超出结节均与颈部LNM无关,P＞0.05；仅与被膜的关系与颈部LNM有关,P＜0.05。结论 超声灰阶声像图对PTMC患者是否发生颈部LNM具有一定预测价值,当PTMC病灶接触被膜时,应在术中清扫中央区淋巴结。 |

| Abstract: |
| Objective:To investigate the relationship between ultrasonic gray scale sonogram features of papillary thyroid microcarcinoma(PTMC) and cervical lymph node metastasis(LNM),and to analyze the predictive value of ultrasonic gray scale sonogram features on cervical LNM in PTMC.Methods:83 patients with PTMC admitted to our hospital from May 2016 to May 2018 were enrolled in this study.All the subjects were examined by gray scale ultrasonography.The characteristics of gray scale ultrasonography were analyzed,and the relationship between gray scale ultrasonography and cervical LNM was observed by regression analysis.Results:Sex,age,lesion diameter,location,aspect ratio,type of internal calcification,relationship with capsule and whether microcalcifications exceed nodules were all related to cervical LNM(P<0.05).The edge and internal echoes in ultrasound gray scale sonographic features were not related to neck LNM,P>0.05.Multivariate regression analysis showed that sex,age,lesion diameter,location,aspect ratio,type of internal calcification and whether microcalcification exceeded nodules were not related to LNM,P>0.05.The relationship only with the capsule is related to the LNM of the neck,P<0.05.Conclusion:Ultrasonic gray scale sonogram has certain predictive value for the occurrence of cervical LNM in PTMC patients.When PTMC lesions touch the capsule,central lymph nodes should be removed during operation. |
