结肠癌组织中WWP1、C-myc的表达及临床意义

目的检测WWP1、C-myc在结肠癌组织中的表达,探究其与结肠癌患者病情进展、预后的关系。方法采用免疫组织化学法检测河北北方学院附属第一医院收治的135例结肠癌患者的癌组织、癌旁正常组织中WWP1、C-myc蛋白表达情况,分析癌组织中WWP1、C-myc表达与患者临床病理参数、无进展生存期(PFS)及总生存期(OS)的关系,用Cox回归分析结肠癌预后的危险因素。结果结肠癌组织WWP1、C-myc蛋白阳性表达率高于癌旁正常组织(P<0.05);结肠癌组织WWP1、C-myc蛋白表达受Dukes分期、肿瘤浸润深度及淋巴结转移的影响较大(P<0.05);Kaplan-Meier生存分析表明,结肠癌组织WWP1、C-myc阳性表达患者术后PFS、OS较短(P<0.05);Cox回归分析结果显示,分化程度[RlR=29.203(95%CI:4.759,179.192)]、肿瘤Dukes分期[RlR=16.817(95%CI:2.765,102.271)]、浸润深度[RlR=3.285(95%CI:1.450,7.442)]、淋巴结转移[RlR=18.723(95%CI:4.131,84.861)]、WWP1表达[RlR=11.344(95%CI:3.472,37.060)]及C-myc表达[RlR=12.873(95%CI:3.092,53.592)]为影响结肠癌患者预后的独立危险因素。结论结肠癌组织中WWP1、C-myc异常高表达,且与患者病情恶性进展、预后不良关系密切,WWP1、C-myc可作为预测结肠癌患者预后的参考指标。

Correlation of RUNX3 expression with microvessel density in colorectal adenocarcinoma tissues and clinical significance

Objective: To study the expression of RUNX3 in colorectal adenocarcinoma tissues and its correlation with microvessel density(MVD),and investigate the clinical pathological prognostic significance of RUNX3 and MVD in patients with colorectal cancer,Methods: The expression value of RUNX3 and MVD in 70 specimens' colorectal adenocarcinoma tissues were detected by immunohistochemistry staining technique,The correlation between their expression and the clinicopathologic features was also investigated,Results: The expression value of RUNX3 and the positive rates of RUNX3 in colorectal adenocarcinoma tissues were 3.25±1.14 and 25.71%(18/70),The expression value of MVD in colorectal adenocarcinoma tissues was 13.14±3.23,Expression of RUNX3 and MVD value were correlated with CEA,serosal invasion,liver metastasis,lymph node metastasis,and TNM stage(P<0.01),The expression value of RUNX3 had negative correlations with that of MVD,Conclusions: The high expression of RUNX3 could inhibit tumor microvascular generation in order to have negative control response on invasion and distant metastasis.
