目的　探讨隐匿性甲状腺癌淋巴结及血行转移特点，为手术治疗提供依据。方法　对６４ 例隐匿性甲状腺癌临床资料进行回顾性分析。结果　颈淋巴结转移３９ 例，转移率６０．９ ％ ；血行转移３ 例，转移率４．６ ％ 。转移与病理类型及肿瘤局部浸润程度有关，与原发灶大小无关。结论　隐匿性甲状腺癌转移特点与其同型的显性甲状腺癌相一致，治疗应遵循同类型显性癌的治疗原则。 Objective To investigate the characteristics of lymph node and hematogenous metastasis of occult thyroid carcinoma, and provide basis for surgical treatment. Methods The clinical data of 64 cases of occult thyroid cancer were analyzed retrospectively. Results In 39 cases of cervical lymph node metastasis, the metastasis rate was 60.9 %; blood metastasis was found in 3 cases and the metastatic rate was 4.6%. The metastasis was related to the type of pathology and the degree of local infiltration of the tumor, and had nothing to do with the size of the primary tumor. Conclusion The occult thyroid cancer metastasis is consistent with its isotype of dominant thyroid carcinoma. The treatment should follow the principle of treatment of the same type of dominant cancer.
