摘要:
目的 探讨尾型同源盒转录因子2(CDX2)与环氧合酶-2(Cox-2)、VEGF在结肠癌组织的表达及意义.方法 采用免疫组化SP法检测CDX2与COX-2、VEGF在62例结肠癌组织、20例正常结肠组织中的表达情况,探讨CDX2、COX-2、VEGF与结肠癌临床病理特征的关系.结果 CDX2在结肠癌、正常结肠组织中阳性表达率分别为54.8％、95.0％,COX-2在结肠癌、正常结肠组织中阳性表达率分别为75.8％、20.0％,VEGF在结肠癌、正常结肠组织中阳性表达率分别为80.6％、25.0％.CDX2在结肠癌组织中表达阳性率显著低于正常结肠组织(P＜0.05),COX-2、VEGF在结肠癌组织中表达阳性率显著高于正常结肠组织(P＜0.05).CDX2、COX-2、VEGF在结肠癌阳性表达与患者肿瘤浸润深度、有无淋巴结转移相关.Spearman相关分析显示,CDX2与COX-2、VEGF在结肠癌组织中表达均呈负相关(P＜0.05),COX-2和VEGF在结肠癌组织中表达呈显著正相关(P＜0.05).结论 CDX2、COX-2、VEGF的表达与结肠癌的发生、发展及预后关系密切.
Abstract:
Objective To explore expressions and clinical significance of CDX2,COX-2 and VEGF in colon carcinoma tissues.Methods The expressions of CDX2,COX-2 and VEGF in colon carcinoma tissues of 62 cases and normal colon tissuesof 20 cases were detected by immunohistochemical SP methods.Relationships between clinical pathological features and CDX2,COX-2 andVEGF were analyzed.Results The positive expression rates of CDX2 in colon carcinoma tissues and normal colon tissues were 54.8％ and 95.0％ respectively,the positive expression rates of COX-2 in colon carcinoma tissues and normal colon tissues were 75.8％ and 20.0％,and the positive expression rates of VEGF in colon carcinoma tissues and normal colon tissues were 80.6％ and 25.0％.The positive expression rate of CDX2 in colon carcinoma tissues was significantly lower than that in normal colon tissues(P ＜ 0.05),the positive expression rates of COX-2 and VEGF in colon carcinoma tissues were significantly higher than those in normal colon tissues (P ＜ 0.05).The positive expressions of CDX2,COX-2 and VEGF in colon carcinoma tissues were related with invasive depth and lymph node metastasis (P ＜ 0.05).Spearman correlation analysis results showed that expression of CDX2 was negatively correlated with COX-2 and VEGF in colon carcinoma tissues (P ＜ 0.05),and COX-2 was positively correlated with VEGF in colon carcinoma tissues (P ＜ 0.05).Conclusion The expressions of CDX2,COX-2 and VEGF are closely related with the occurrence,development and prognosis of colon carcinoma.
