Abstract

目的 研究胰腺癌组织中血管内皮生长因子(vascular endothelial growth factor,VEGF)表达和肿瘤相关巨噬细胞(tumour-associated macrophages,TAMs)计数与淋巴结转移的关系.方法 采用免疫组织化学染色,在光镜下对VEGF阳性细胞评分及TAMs计数进行分析.结果 胰腺癌组织中VEGF表达阳性率明显高于正常组织(P<0.01);淋巴结转移组VEGF的表达和TAMs计数较未转移组明显增高(P<0.05);VEGF的表达与胰腺癌临床病理分期无明显关系(P>0.05);TAMs计数与胰腺癌临床病理分期有明显关系(P<0.01);VEGF的表达与TAMs计数呈正相关(r=0.663,P<0.01).结论 VEGF和TAMs的表达均与胰腺癌淋巴结转移有密切关系。
