1、唾液腺腺样囊性癌中Runx3的表迗及临床意义[摘要]目的探讨唾液腺腺样囊性癌(SACC)中Runx3的表迗及与临床病理因素的相关性。方法采用荧光定量RT-PCR检测Runx3在6例SACC组织及正常唾液腺组织中的表达。免疫组化检测58例SACC和正常唾液腺组织中Runx3蛋白的表迗。采用SPSS17.0软件包分析Runx3的表迗程度与临床病理因素之间的相关性。结果qRT-PCR的测量显示唾液腺腺样囊性癌中Runx3mRNA表达明显下调。免疫组化结果显示,Rimx3在SACC中的表迗与病理类型(实体型)、T临床分期及淋巴结
2、转移显著相关,而与肿瘤远处转移存在弱相关。结论Runx3表迗下调与SACC发生发展相关,可能是临床诊断和治疗SACC的重要生物标志物。[关键词]Runx3;唾液腺;腺样囊性癌;RT-PCR[中图分类号]R739.8[文献标识码]A[文章编号]1673-9701(2015)25-0001-03ExpressionandclinicalsignificanceofRunx3insalivaryadenoidcysticcarcinomaXUZhengyuanlHEJianfeng21.DepartmentofStomatol
