【摘要】目的:初步探讨DEAR1蛋白在甲状腺乳头状癌(papillary thyroid carcinoma,PTC)中的表达情况及其临床意义。方法:采用免疫组化检测60例甲状腺乳头状癌组织及对应癌旁组织中DEAR1蛋白的表达情况,分析DEAR1表达与临床病理因素之间的相关性。结果:DEAR1蛋白在PTC组织中表达量显著低于癌旁组织,差异有统计学意义(P0.05)。结论:DEAR1蛋白表达缺失与PTC的发生、发展可能存在密切联系,且在PTC增殖、包膜侵犯和颈部淋巴结转移中可能发挥着一定的作用。

Expression and Clinical Significance of DEAR1 Protein in Papillary Thyroid Carcinoma/JIANG Liehao,TAN Zhuo,YIN Kexin,et al.//Medical Innovation of China,2018,15(26):005-009

【Abstract】 Objective:To investigate the expression of DEAR1 in papillary thyroid carcinoma(PTC)and its para-carcinoma tissues and evaluate the association between DEAR1 expression and clinicopathologic factors.Method:Immunohistochemistry was used to evaluate the expression of DEAR1 in 60 cases of PTC and para-carcinoma tissues and the relationship between DEAR1 expression and clinicopathologic factors were analyzed.Result:The expression of DEAR1 was significantly down-regulated in PTC tissues compared to para-carcinoma tissues

(P0.05).Conclusion:The low expression of DEAR1 may relate to the development of PTC,and it may play an important role in proliferation,capsular invasion and Lymph node metastasis of papillary thyroid carcinoma.

甲状腺癌是最常见的内分泌肿瘤,近年来甲状腺癌的发病率快速上升,已被列入恶性肿瘤的前10位[1]。根据2016年美国国家癌症署数据显示,全世界新发的甲状腺癌以平均每年大于5%的速度递增,其中增长最快的是甲状腺乳头状癌(papillary thyroid carcinoma,PTC)[2]。虽然绝大多数PTC预后优异,10年生存率可达90%以上,但约有50%的患者在发现时已经存在颈部淋巴结转移,有10%~20%的病例会出现反复发作及远处转移,一旦发生远处转移,10
