目的:探讨血管内皮生长因子(VEGF)、基质金属蛋白酶2(MMP-2)、基质金属蛋白酶9(MMP-9)表达与肝癌患者临床病理特征及预后的关系，为肝癌发生发展机制提供依据。方法:选择2015年4月至2016年3月在义乌市中心医院手术切除的肝癌组织95例，选择因肝外伤切除的正常肝组织标本45例作为对照。采用免疫组化染色法检测肝癌组织及正常肝组织VEGF、MMP-2、MMP-9表达情况，并分析VEGF、MMP-2、MMP-9表达与患者临床病理及预后的相关性。结果:肝癌组织中VEGF、MMP-2以及MMP-9阳性表达率均明显高于正常肝组织(81.05%、75.79%、84.21%比42.22%、33.33%、48.89%)(χn 2＝21.364、23.397、19.265，均n P<0.05)。肝癌组织低分化、TNM分期Ⅲ～Ⅳ期以及有血管侵袭患者肝癌组织VEGF、MMP-2、MMP-9表达阳性率均明显升高(均n P<0.05)。肝癌组织VEGF、MMP-2以及MMP-9阴性表达患者生存情况均显著优于阳性表达患者(log χn 2＝3.271、2.975、3.065，均n P<0.05)。n 结论:肝癌组织中VEGF、MMP-2以及MMP-9高表达，在肿瘤生长浸润和转移过程中发挥了重要作用，因此VEGF、MMP-2以及MMP-9可作为肝癌进展的生物学指标。“,”Objective:To investigate the correlation between the expression of vascular endothelial growth factor (VEGF), MMP-2, MMP-9 and the clinicopathology and prognosis of patients with hepatocellular carcinoma (HCC), and to provide evidence for the occurrence and development of HCC.Methods:From April 2015 to March 2016, 95 HCC tissues were resected in Yiwu Central Hospital.Forty-fivenormal liver tissues which were resected due to liver trauma were selected as control group.Immunohistochemical staining was used to detect the expression of VEGF, MMP-2 and MMP-9 in HCC and normal liver tissues, and the correlation between the expression of VEGF, MMP-2, MMP-9 and clinical pathology and prognosis was analyzed.Results:The positive expression rates of VEGF, MMP-2 and MMP-9 in the HCC tissues were significantly higher than those in the normal liver tissues (81.05%, 75.79%, 84.21% vs.42.22%, 33.33%, 48.89%)(χn 2=21.364, 23.397, 19.265, all n P<0.05). The positive expression rates of VEGF, MMP-2 and MMP-9 in HCC were significantly increased in patients with poor differentiation, TNM stage Ⅲ-Ⅳ and vascular invasion (alln P<0.05). The survival of patients with negative expression of VEGF, MMP-2 and MMP-9 in HCC tissues was significantly better than that of patients with positive expression (log χn 2=3.271, 2.975, 3.065, all n P<0.05).n Conclusion:The high expression of VEGF, MMP-2 and MMP-9 plays an important role in the growth, invasion and metastasis of HCC tissues.Therefore, VEGF, MMP-2 and MMP-9 can be used as biological indicators of the progression of HCC.
