【摘要】 目的分析血管内皮生长因子(vascular endothelial growth factor,VEGF)和基质金属蛋白酶-9(matrix metalloproteinase-9,MMP-9)在前列腺癌中的表达及其相互关系。方法应用免疫组织化学方法,检测148例前列腺癌(prostate cancer,PCa)组织中和10例前列腺增生(benign prostatic hyperplasia,BPH)组织中VEGF和MMP-9的表达。结果前列腺癌组织中VEGF和MMP-9的高表达率分别为66.2%、39.2%,显著高于前列腺增生组(P<0.05)。VEGF和MMP-9的表达与前列腺癌的分化程度及转移有关(P<0.05),与患者的年龄及雄激素受体水平(AR)无关(P>0.05)。且VEGF、MMP-9在前列腺癌中的表达具有相关性。结论VEGF和MMP-9的表达与前列腺癌的发展密切相关,并对前列腺癌的预后判定有一定的意义。更多还原

【Abstract】 Objective To explore the relationship between the expressions of vascular endothelial growth factor(VEGF) and matrix metalloproteinase-9(MMP-9) in prostate cancer.Methods The expression of VEGF and MMP-9 in 148 samples of pathologically verified human prostate cancer(PCa) and 10 samples of benign prostatic hyperplasia(BPH) were detected by immunohistochemical staining.Results VEGF was overexpressed in 98 of 148 tumor tissues(66.2%) and MMP-9 was overexpressed in 58 of 148 tumor tissues(39.2%).Both of them were significantly higher than those in BPH(P<0.05).The expression of VEGF and MMP-9 was correlated with metastasis and differentiation(P<0.05),but it was not related to the androgen receptor(AR) level and the age of patients(P>0.05).But the expression of VEGF was correlated with that of MMP-9.Conclusion The expressions of VEGF and MMP-9 are closely associated with the development of prostate cancer.Therefore VEGF and MMP-9 may be clinically useful as predictor of patients’survival.更多还原
