| 目的 探讨甲状腺微小乳头状癌( papillary thyroid microcarcinoma , PMC)的超声特征与颈部淋巴结转移相关性因素。
方法 回顾性分析本院2011年1月至2016年6月收治的408例PMC患者，研究PMC结节超声影像学资料及术后颈部淋巴结病理结果，分析PMC超声待征与颈部淋巴结转移(cervical lymph node metastasis，CLNM)的相关因素。
结果 在单变量分析中，男性、肿瘤>5mm、多灶、微钙化、边界模糊、与甲状腺被膜接触、血流丰富、肿瘤位于上极的PMC患者易发生颈淋巴结转移(P<0．05)，在多变量分析中，男性及与甲状腺被膜接触与颈淋巴结转移显著相关(P<0．05)。
结论 男性及与甲状腺被膜接触对PMC患者CLNM具有很好的预测价值。 |

| Abstract: |
| Objective The study evaluated the factors affecting CLNM in patients with papillary thyroid microcarcinoma.Methods A retrospective cohort study was conducted with data obtained from patients with PMC between January 2011 and June 2016.We reviewed the ultrasound and pathology records of patients and analyzed the association between CLNM and ultrasound features of PMC.Results The univariate analysis (χ2test) showed that a number of factors were significantly associated with CLNM in PMC (P<0.05): male gender ,tumor size(>5mm), multifocality，microcalcification，no well-defined margin，the tumor contacted with the adjacent capsule of thyroid，rich vascularity, tumor located at the upper pole.The multivariate analysis (regression binary logistic) showed that male genderand the tumor contacted with the adjacent capsule of thyroid are associated with the neck lymph node metastasis in PMC(P<0.05). Conclusions Male gender and the tumor contacted with the adjacent capsule of thyroid has definite value in predicting CLNM for PMC patients. |
