隐匿性甲状腺癌淋巴结及血行转移因素分析

Factors of lymph node and blood metastasis in occult thyroid carcinoma

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 transfering characteristics of lymph node and blood metastasis in occult thyroid carcinoma(OTC) for the surgical management. Methods Retrospective analysis on the clinical data of 64 cases of OTC. Results Thirty nine patients(60.9%) with cervical lymphatic metastasis and 3 patients(4.6%) with blood metastasis respectively. Metastasis was found to be related to the pathological type and invasive extension of the tumor, exclusive to the size of primary lesion. Conclusions The biological characteristic of OTC accords with that of the same type as thyroid carcinoma, and the relevant treatment also follows on the principals of the same type of thyroid carcinoma.
