摘要 目的检测结直肠腺癌组织中Tiam1、血管内皮生长因子(VEGF)-C和血管内皮生长因子受体(VEGFR)-3的表达,研究三者表达的关系及对预后的判断价值。方法收集结直肠腺癌标本87例作为观察组,正常结肠黏膜组织80例作为对照组。采用免疫组化技术检测两组中Ti-am1、VEGF-C和VEGFR-3的表达特点,研究三者在不同临床特征中的表达不同及对预后的判断价值。结果结直肠腺癌中Tiam1、VEGF-C和VEG-FR-3表达的阳性率明显高于对照组,结直肠腺癌中Tiam1、VEGF-C和VEGFR-3表达均与肿瘤淋巴结转移、淋巴结转移个数、Dukes分期及Ki-67的表达密切相关。线性相关分析显示结直肠腺癌中Tiam1、VEGF-C和VEGFR-3表达具有正相关性。生存分析显示Tiam1、VEGF-C和VEGFR-3的表达均与结直肠腺癌的预后相关。结论结直肠腺癌中Tiam1、VEGF-C和VEGFR-3高表达,三者可能具有协同作用,共同促进肿瘤的发生与进展,术后联合检测Tiam1、VEGF-C和VEGFR-3的表达对判断预后有一定帮助。
