摘要
目的 研究血管内皮生长因子（VEGF）与基质金属蛋白酶9（MMP-9）在胰腺癌（PCA）中的表达及其临床意义.方法 采用免疫组化法对50例胰腺癌（包括癌旁组织）及20例正常胰腺组织手术切除标本的VEGF及MMP-9表达进行检测.结果 VEGF和MMP-9在胰腺癌组织中的表达水平显著高于癌旁组织及正常组织（x2=2.82,2.96,均P〈0.05） 且其表达水平与胰腺癌的分化程、临床分期有关,且在淋巴结转移组与非转移组间表达水平的差异有统计学意义（P〈0.05）.结论 VEGF和MMP-9在胰腺癌生长、侵袭和转移过程中起着重要的作用,对预测胰腺癌复发、转移具有一定的意义.
Objective To investigate the expression of vascular endothelial growth factor （VEGF） or matrix metalloproteinase-9（ MMP-9） in pancreatic carcinoma（ PCA） and its clinical significance.Methods The expression of VECF and MMP-9 in 50 PCA tissues and in 20 normal pancreatic tissues were examined by immunohistochemistry.Results The expression of VECF and MMP-9 was higher in PCA than that in its surrounding parenchyma and normal pancreatic parenchyma（ x2 = 2.82,2.96, all P 〈 0.05 ） The expression of VEGF and MMP-9 were related to the tumor differentiation,the clinical stage and the lymphnode metastasis.Conclusion VECF and MMP-9 should play important role in the invasion and metastasis of PCA, and had a certain significance for predicting recurrence and metastasis of pancreatic cancer.
