摘要 目的应用免疫组化方法检测胃腺癌中富含亮氨酸重复序列G-蛋白耦联受体(LGR)5、血管内皮生长因子(VEGF)和其受体(VEGFR)2的表达。方法 58例胃腺癌患者的临床资料及术后蜡块组织作为研究组,选择上述患者在距肿物边缘>5 cm、经病理主治医师证实为非癌组织的胃黏膜组织的蜡块组织47例作为对照组,应用免疫组化方法检测LGR5、VEGF和VEGFR2的表达。结果研究组中LGR5、VEGF和VEGFR2的阳性率均明显高于对照组,研究组中LGR5、VEGF和VEGFR2的阳性率与浸润深度和脉管浸润相关,LGR5的阳性率与分化程度、Ki67增殖指数相关,VEGF和VEGFR2的表达与肿瘤的最大径相关。相关性分析显示研究组中LGR5和VEGF、VEGF和VEGFR2均具有正相关性。结论 LGR5、VEGF和VEGFR2在胃腺癌术后组织中高表达,三者可以促进肿瘤的形成和进展。LGR5可能与VEGF和VEGFR2蛋白的表达有协同作用。
