目的: 研究甲状腺微小乳头状癌的外科治疗效果及其腺外侵犯、淋巴结转移等侵袭性的发生情况。
方法: 回顾性分析内蒙古医科大学附属医院甲乳外科近3a 经外科治疗的909 例甲状腺微小乳头状癌病人临床
资料，统计分析病人甲状腺腺外侵犯、手术方式和淋巴结转移的风险程度。结果: 909 例甲状腺微小乳头状癌病
人中总的淋巴结转移率为36．5%，中央区淋巴结转移率率30．9%，术后主要并发症发生率3．74%; 另外，单因素分
析显示所有病人的肿瘤大小与病人年龄、性别均无关( P＞0．05) ，而肿瘤大小与甲状腺外侵犯和淋巴结转移有关
( P＜0．05) ，多因素分析结果证明肿瘤大小、手术方式与甲状腺外侵犯和淋巴结转移有关( P＜0．05) 。结论: 甲状
腺微小乳头状癌病人的肿瘤大小、腺外侵犯、手术方式和淋巴结转移等侵袭性密切相关，规范化和个体化的外科
手术方式明显增加甲状腺微小乳头状癌的外科治疗效果。

Objective: To study the surgical treatment of papillary thyroid microcarcinoma and the
incidence of thyroid gland invasion， lymph node metastasis and other invasion．Methods: The clinical
data of 909 patients with papillary thyroid microcarcinoma who underwent surgical treatment of department
of thyroid breast surgey，Affiliated hospital， Inner Mongolia Medical College from January 2014 to
December 2016 were analyzed retrospectively，and the risk of thyroid gland infection， surgical methods
and the degree of lymph node metastasis was statistical Analysised．Ｒesults: The total lymph node metastasis
rate of 909 cases of papillary thyroid microcarcinoma was 37．7%．The central lymph node metastasis
rate of them was 29．5%．The incidence of major postoperative complications was statistically significant
of them was 3．74%．In addition，univariate analysis showed that the tumor size of patients with papillary
thyroid microcarcinoma was not associated with age and sex( P＞0．05) and the tumor size was associated
with thyroid gland invasion and lymph node metastasis( P＜0．05) ．Multivariate analysis showed
that the tumor size and operation were related to thyroid gland invasion and lymph node metastasis( P＜
0．05) ． Conclusions: The tumor size，thyroid gland invasion，surgical approach and lymph node
metastasis in patients with papillary thyroid microcarcinoma are closely related，and the standardized
and individualized surgical methods can significantly increase the surgical treatment of papillary thyroid
microcarcinoma．
