VEGF和MMP-2表达与肝细胞肝癌复发和预后的关系

Expression of Vascular Endothelial Growth Factor and Matrix Metalloproteinase 2 in Hepatocellular Carcinoma and Its Relationship with Rucurrence and Prognosis

  • 摘要: 目的 :研究血管内皮生长因子(VEGF)和基质金属蛋白酶2(MMP-2)在肝细胞肝癌(HCC)中的表达与HCC复发转移的关系。 方法 :按是否复发将93例肝癌患者分为复发组与未复发组,采用免疫组化方法检测两组标本中VEGF及MMP-2的表达情况,分析两者的表达与临床病理指标的关系。 结果 :VEGF与MMP-2在93例HCC中的阳性表达率分别为52.69%与67.74%,复发组(44例)的阳性表达率分别为68.18%(30/44)、88.64%(39/44);未复发组(49例)的阳性表达率分别为36.78%(19/49)、48.98%(24/49),两组之间差异具有统计学意义(P<0.05)。生存分析显示术后两年生存率MMP-2(+)与(-)组分别为41.42%、63.36%,差异具有统计学意义(P<0.05);VEGF(+)与(-)两年生存率分别为48.50%、52.21%,差异不具有统计学意义(P>0.05)。 结论 :MMP-2表达高的肝癌,转移复发率高,预后差。

     

    Abstract: Objective : To investigate the expression and clinical impact of vascular endothelial growth factor (VEGF) and matrix metalloproteinase 2 (MMP-2) in hepatocellular carcinoma (HCC). Methods : We collected 93 HCC resection samples with complete clinical and prognostic data. Immunohistochemical staining of VEGF and MMP-2 were conducted in recurrent group (44) and non-recurrent group (49). Correlations of the expression of MMP-2 and VEGF with clinicopathologic features were analyzed. Results : The positive rates of VEGF and MMP-2 expression in HCC tissues were 52.69% and 67.74%, respectively. These two indices were expressed in cytoplasm. The positive rates of VEGF and MMP-2 were significantly higher in recurrent group than in non-recurrent group (68.18% vs. 88.64%; 36.78% vs. 48.98%). The 2-year tumor free survival rates of MMP-2 (+) group and MMP-2 (-) group were 41.42% and 63.36%, respectively. The MMP-2 (+) group has a lower survival rate than the MMP-2 (-) group (P =0.0142). The 2-year survival rates of VEGF (+) group and VEGF (-) group were 48.50% and 52.21%, respectively, with no statistical significance (P =0.1834). Conclusion : HCC which highly expresses MMP-2 has a higher rate of recurrence, a lower survival rate, and a poorer prognosis. The expression of MMP-2 can be used to estimate the risk of postoperative recurrence of HCC.
