摘要 目的探讨结直肠癌组织β-catenin表达与肿瘤芽的关系及其临床意义。方法应用免疫组织化学染色,检测217例结直肠癌的肿瘤主体、浸润前缘及肿瘤芽β-catenin核表达情况,分析其临床病理意义及其与患者预后的关系。结果在管状腺癌和乳头状腺癌的肿瘤主体、浸润前缘β-catenin核表达体阳性率(肿瘤主体分别为49.1%和42.3%、浸润前缘分别为45.3%和38.5%)高于黏液或印戒细胞癌(14.3%,P=0.003;17.9%,P=0.023)。单因素生存分析显示,肿瘤芽(-)组5年累计生存率为78%.肿瘤芽(+)、β-catenin(+)5年累计生存率为76%,两组比较,差异无统计学意义(P=0.457);肿瘤芽(+)、β-catenin(+)组5年累计生存率明显高于肿瘤芽(+)、β-catenin。(-组(76%,53%,P=0.031)。结论β-catenin(-)、肿瘤芽(+)的结直肠癌患者预后较差。
