摘　　要：目的探讨结肠癌组织中β-连环蛋白(β-catenin)/转录因子4(TCF4)信号通路相关蛋白表达及其与患者术后复发转移的关系。方法选择驻马店市中心医院2020年1月至2022年1月收治的结肠癌患者86例为研究对象,患者均接受手术切除。采用实时荧光定量聚合酶链式反应检测患者癌组织及癌旁组织中Wnt-1、β-catenin、TCF4 mRNA的表达,免疫组织化学法检测Wnt-1、β-catenin、TCF4蛋白的表达,Cox比例回归模型分析结肠癌患者术后复发转移的危险因素。结果结肠癌患者癌组织中Wnt-1、β-catenin、TCF4 mRNA相对表达量和蛋白表达阳性率显著高于癌旁组织(P<0.05)。Wnt-1、β-catenin、TCF4蛋白表达阳性率与肿瘤浸润程度、肿瘤分期以及淋巴结转移有关(P<0.05),Wnt-1、β-catenin、TCF4的蛋白表达阳性率与结肠癌患者年龄、性别、肿瘤大小、分化程度无关(P>0.05)。Cox回归分析结果显示,有淋巴结转移、Wnt-1、β-catenin、TCF4蛋白表达阳性是结肠癌患者术后复发转移的危险因素(P<0.05)。结论结肠癌组织中Wnt-1、β-catenin、TCF4 mRNA表达及蛋白表达阳性率均较高,Wnt-1、β-catenin、TCF4蛋白表达阳性率与肿瘤浸润程度、肿瘤分期以及淋巴结转移显著相关,是结肠癌术后复发转移的危险因素。Objective To investigate the expressions of theβ-catenin/transcription factor 4(TCF4)signaling pathway-related proteins in colon cancer tissues and their relationship with postoperative recurrence and metastasis of colon cancer.Methods A total of 86 patients with colon cancer admitted to Zhumadian Central Hospital from January 2020 to January 2022 were selected as the research subjects,all of whom underwent surgical resection of the colon.Real-time fluorescence quantitative polymerase chain reaction was used to detect the expression levels of Wnt-1,β-catenin and TCF4 mRNA in cancer tissues and adjacent tissues of patients,and immunohistochemistry was used to detect the protein expression levels of Wnt-1,β-catenin and TCF4.The Cox proportional hazards regression model was used to analyze the risk factors of postoperative recurrence and metastasis of colon cancer.Results The relative mRNA expression levels and protein expression positive rates of Wnt-1,β-catenin and TCF4 in cancer tissues were significantly higher than those in adjacent tissues of colon cancer patients(P<0.05).The expression positive rates of Wnt-1,β-catenin and TCF4 protein were correlated with the degree of tumor invasion,tumor stage and lymph node metastasis(P<0.05),but not correlated with age,sex,tumor size and differentiation degree(P>0.05).Cox regression analysis showed that lymph node metastasis,and positive protein expressions of Wnt-1,β-catenin and TCF4 were risk factors for postoperative recurrence and metastasis of colon cancer(P<0.05).Conclusion The mRNA expression levels and protein expression positive rates of Wnt-1,β-catenin and TCF4 are higher in colon cancer tissues.The protein expression positive rates of Wnt-1,β-catenin and TCF4 are significantly correlated with the degree of tumor invasion,tumor stage and lymph node metastasis,and are risk factors for postoperative recurrence and metastasis of colon cancer.
