摘要 目的检测T淋巴瘤侵袭转移诱导因子1(Tiam1)在正常胃黏膜组织、不典型增生组织、胃癌组织及淋巴结转移灶的表达,探讨Tiam11与胃癌侵袭及转移的关系。方法应用免疫组化方法检测42例正常胃黏膜组织、53例不典型增生组织、86例胃癌及40例淋巴结转移灶中Tiam1蛋白的表达,分析其与胃癌临床病理因素间的关系。结果Tiam1蛋白在正常胃黏膜组织中表达(11.9%)显著低于不典型增生组织(49.1%)、癌组织(83.7%)和淋巴结转移灶(90.0%),差异有显著性(P<0.01),且随胃癌组织浸润深度的增加及伴有淋巴结转移,Tiam1蛋白阳性率逐渐升高,差异有显著性(P<0.05或P<0.01)。但Tiam1蛋白表达水平与胃癌患者的性别、年龄及组织类型无关(P>0.05)。结论随着胃癌的侵袭及转移,Tiam1表达呈上升趋势,与胃癌进展转移呈正相关。Tiam1基因有可能成为肿瘤治疗的新靶点。
