摘要 目的:探讨β-连环蛋白(β-catenin)在大肠肿瘤中的表达及其在大肠癌发生、发展中作用。方法:采用免疫组织化学(SP法)对23例大肠腺瘤及62例大肠癌标本中β-catenin的表达进行检测。结果:β-catenin在大肠癌表达缺失率、异位表达率高于大肠腺瘤中相应表达率(P=0.00,P=0.027);大肠癌组织中β-catenin蛋白的表达缺失率、异位表达率及表达程度在中、低分化间,高、低间相比,差异有统计学意义(P<0.05);在浸透浆膜组高于未浸透浆膜组,在淋巴结有转移组高于淋巴结无转移组,TNM分期(Ⅲ+Ⅳ期)高于(Ⅰ+Ⅱ期),差异均有统计学意义(P<0.05)。结论:β-catenin与大肠癌的发生、发展、侵袭及转移有密切关系。
