objective:our aim is to investigate the relationship of vegf c,vegf d and lymph node metastasis in pancreatic cancer,and to elucidate the role and significance of the cancerous peripheral lymphatic tissue.methods: the expression of vegf c and vegf d was assayed by means of immunohistochemistry in 30 pancreatic carcinomas.results:the positive rates of vegf c、vegf d were 73%(22/30)、57%(17/30) respectively in pancreatic cancer.the expression of vegf c、 vegf d in cancerous invasive edge was significantly higher than that in the center of cancerous tissues.there was no correlation between the expression of vegf c、vegf dand the site,differentiation,histology types.

目的：探讨胰腺癌中vegf c、vegf d蛋白表达与淋巴结转移之间的相关关系，阐明癌周淋巴管增生在胰腺癌淋巴转移中的作用及意义。方法：免疫组化检测30例胰腺癌组织中vegf c、vegf d的表达及其与临床病理、淋巴结转移的关系。结果：胰腺癌vegf c、vegf d蛋白表达阳性率分别为73%(22/30)、57%（17/30），肿瘤周边部位显著高于肿瘤中心部位，其表达与肿瘤的部位、分化程度、组织学类型无关，与肿瘤的tnm分期有关，ⅲ~ⅳ期显著高于ⅰ~ⅱ期。
