摘要 目的:探讨碳酸酐酶Ⅸ(CAⅨ)在食管腺癌中的表达情况及其临床意义。方法:采用免疫组化SP法和RT-PCR检测45例食管腺癌组织、癌旁不典型增生组织、正常食管组织中CAⅨ的阳性表达及其CAⅨm RNA的相对表达量情况。结果:CAⅨ蛋白在食管腺癌组织、癌旁不典型增生和正常食管组织中的阳性表达率依次为66.7%(30/45),24.4%(11/45),4.4%(2/45),三者两两比较差异具有统计学意义(χ2=41.845,P=0.001)。食管腺癌组织中CAⅨ蛋白的表达与肿瘤浸润深度、淋巴结转移、分化程度及临床分期有关(P=0.001),与性别年龄无关(P=0.664)。RT-PCR结果显示CAⅨ基因在食管不同组织中均有表达,分别为0.217±0.017,0.436±0.03,0.544±0.043,差异有统计学意义(χ2=60.614,P=0.001)。结论:CAⅨ蛋白可能促使食管腺癌的发生,检测CAⅨ有助于食管腺癌诊断治疗以及预后判断。
