摘要 目的探讨T淋巴瘤侵袭转移诱导因子1(T-lymphoma invasion and metastasis-inducing factor,Tiam1)、赖氨酰氧化酶(lysyl oxidase,LOX)mRNA的表达与结直肠癌淋巴结微转移及预后的关系。方法收集2014年8月至2017年6月在中国人民解放军总医院第七医学中心普外科手术切除的结直肠癌患者病灶组织样本与癌旁组织样本78例,采用免疫组化法测定淋巴结微转移情况,采用反转录-聚合酶链反应检测Tiam1、LOX mRNA表达情况,同时随访患者的生存情况与一般情况,最后进行相关性分析。结果在78例样本中,病灶组织样本检出淋巴结微转移20例,检出率为25.6%;在癌旁组织样本中检出淋巴结微转移2例,检出率为2.6%,两组比较差异有显著性(P<0.05)。病灶组织样本中的Tiam1、LOX mRNA阳性表达率分别为43.6%、89.7%,癌旁组织样本分别为2.6%、3.8%,两组比较差异有显著性(P<0.05)。所有患者均获得随访,平均(33.52±1.31)个月,随访生存45例,生存率57.7%。Tiam1 mRNA阳性患者的结直肠癌淋巴结微转移率显著高于阴性患者,生存率显著低于阴性患者,两组比较差异有显著性(P<0.05)。Kaplan-Meier生存分析也显示Tiam1 mRNA阳性表达患者的生存期低于阴性表达患者(P<0.05)。Cox模型多因素风险回归分析显示LOX mRNA表达、Tiam1 mRNA表达、淋巴结微转移都是影响患者预后生存的主要独立危险因素(P<0.05)。结论Tiam1、LOX在结直肠癌侵袭转移过程中具有重要作用,Tiam1、LOX mRNA的表达与结直肠癌淋巴结微转移及预后存在显著相关,也是影响患者预后的危险因素。
