摘要 目的研究Bmi-1和CD133在食管癌组织和癌旁正常组织中的表达及其与临床病理特征的关系。方法收集手术切除食管癌的石蜡标本90份,采用免疫组织化学法对手术标本石蜡切片进行染色,检测Bmi-1、CD133蛋白的表达,并分析Bmi-1和CD133与临床病理特征的关系。结果随着浸润深度增加,Bmi-1蛋白的阳性表达率升高(<0.05);有淋巴结转移的患者的Bmi-1蛋白阳性表达率明显高于无淋巴结转移者(<0.05);TNM分期中的Ⅲ和Ⅳ期患者Bmi-1表达高于Ⅰ和Ⅱ期患者(<0.05)。随着浸润深度增加,CD133的阳性表达率上升(<0.05);有淋巴结转移患者的CD133阳性表达率明显高于无淋巴结转移者(<0.05);CD133在低分化食管癌组织阳性表达率更高(<0.05)。结论 Bmi-1、CD133蛋白在食管癌组织表达状态与食管癌的生长和浸润转移关系密切,对食管癌患者预后评估有一定的参考价值。
