1、Pim-3和MCM7在食管鳞癌组织中的表达及临床意义别良玉1,张伟杰1,2,任川川3,王琳1,孙桢4,杜雅冰1,王生1,樊青霞1#(1郑州大学第一附属医院肿瘤科,2郑州大学肿瘤中心,3河南省高等学校临床医学重点学科开放实验室郑州 450052;4许昌市中心医院肿瘤科许昌461000)【摘要】目的:探讨Pim-3和MCM7在食管鳞癌组织中的表达及临床意义。方法:采用免疫组化SP法检测77例食管鳞癌组织、70例癌旁不典型增生组织及46例正常食管黏膜组织中Pim-3和MCM7的表达情况,分析Pim-3和MCM7的表达与各临床病理因素的关系。结果:Pim-3和MCM7蛋白在食管癌组
2、织中阳性表达率分别为93.51%和93.51%,显著高于癌旁不典型增生组织(24.29%,62.86%)及正常食管黏膜组织(13.04%,52.17%)的表达率(P<0.05)。Pim-3和MCM7蛋白的阳性表达率与TNM分期、淋巴结转移呈正相关。MCM7蛋白的表达与癌细胞分化程度、外膜浸润有关。而两者的阳性表达率与病人的发病年龄、性别、肿瘤部位、大体病理形态及肿瘤大小无相关性。结论:Pim-3和MCM7蛋白在食管鳞癌组织中的表达异常增高,且与癌细胞分化程度、TNM分期、是否伴淋巴结转移及有无膜外浸润密切相关,可作为食管癌早期诊断指标。关键词:Pim-3;MCM7;食管鳞癌
