摘要
目的 :探讨下咽癌甲状腺转移规律及下咽癌手术中甲状腺叶切除的适应症。方法 :对 2 7例下咽癌甲状腺切除标本进行病理学研究 ,分析下咽癌甲状腺转移与下咽癌原发部位、TNM分期和分化程度的关系。结果 :甲状腺转移性鳞状细胞癌 5例 ,转移率 18 5 %。其中 ,梨状窝癌 3例 (T3 N2 M0 、T4 N2 M0 和T4 N3 M0 各 1例 ,Ⅰ级、Ⅱ级和Ⅲ级各 1例 ) ,环后癌 2例 (T4 N0 M0 ,Ⅱ级 )。结论 :下咽癌甲状腺转移多见于晚期梨状窝癌和环后癌。下咽癌手术中是否同时切除患侧甲状腺叶应根据手术指征来决定 ,但晚期梨状窝癌和环后癌 ,应预防性切除患侧甲状腺叶。
Objective:To explore the pattern of thyroid metastasis and the indications of thyroid lobectomy in hypopharyngeal carcinoma.Methods:after histopathological examination of 27 resected thyroid specimens in hypopharyngeal carcinoma,we evaluated whether thyroid metastasis was related to primary area,TNM-stage,and differentiation degree.Result:Metastasized thyroid squamous cell carcinoma was proved in 5 cases,metastasized ratio was 18.5%.Among these 5 cases,3 cases were pyriform sinus carcinoma(T 3N 2M 0,T 4N 2M 0 and T 4N 3M 0,each in 1,respectively,and degree Ⅰ,Ⅱ and Ⅲ each in 1,respectively),2 cases were retrocricoid region carcinoma(T 4N 0M 0,degree-Ⅱ).Conclusion:Terminal pyriform sinus carcinoma and retrocricoid region carcinoma were prone to give thyroid metastasis.In hypopharyngeal carcinoma operation whether thyroid lobectomy being carried out or not was determined by indication,however,prophylactic thyroid lobectomy was necessary for terminal pyriform sinus carcinoma and retrocricoid region carcinoma.
