摘要 目的检测结肠腺癌中TPX2、PTEN和Ki67的表达及临床价值。方法选择122例结肠腺癌术后留取的蜡块及患者的临床资料作为观察组,选择73例正常结肠黏膜组织作为对照组,采用免疫组织化学方法检测两组中TPX2、PTEN和Ki67的表达。结果观察组中TPX2和Ki67表达的阳性率明显高于对照组(P<0.05),观察组中PTEN表达的阳性率明显低于对照组(P<0.05),观察组中TPX2、PTEN和Ki67表达的阳性率与淋巴结转移、远处转移、浸润深度和临床分期密切相关(P<0.05)。相关分析显示观察组中TPX2和Ki67(r=0.45,P=0.043 2)的表达呈正相关,而PTEN和Ki67(r=-0.48,P=0.030 4)的表达呈负相关。结论结肠腺癌中TPX2和Ki67高表达、PTEN低表达时对病变的发生和进展均具有重要促进作用。TPX2和PTEN对增殖作用的影响可能是影响肿瘤进展的重要机制。
