摘要
目的探讨尿激酶型纤溶酶原激活物受体(uPAR)和血管内皮生长因子-C(VEGF—C)在原发性肝细胞癌中的表达及其与肝癌部分生物学行为的关系。方法采用常规sP免疫组织化学染色法检测33例原发性肝细胞癌标本中uPAR和VEGF—C的表达,分析其表达水平与肝癌部分生物学行为的关系。结果uPAR和VEGF—C定位于肝癌细胞细胞质,在33例原发性肝细胞癌中,uPAR阳性表达率为69.7%(23/33),VEGF—C阳性表达率为78.8%(26/33)。肝癌转移组的uPAR和VEGF—C阳性表达率均明显高于无转移组,二者比较差异均有统计学意义(P〈0.05),但它们的表达与组织学分级、肿瘤大小、是否伴有肝硬化、AFP表达等均无相关性。uPAR和VEGF—C在肝癌组织中的阳性表达呈正相关(r=0.676,P〈0.01)。结论uPAR和VEGF—C的表达与肿瘤侵袭、转移的发生有关,可作为估计预后的指标,对判断肝癌的恶性程度,预测及生物学行为具有一定的临床意义。
Objective To investigate the expression of uPAR and VEGF-C in hepatocellular carcinoma (HCC) and its effect on the biological behavior of HCC. Methods The expression of uPAR and VEGF-C in liver tissue specimen of 33 patients with HCC was detected by immunohistoehemieal staining. Results The positive expression of uPAR and VEGF-C in HCC tissues was located in cytoplasma of cancer cells. The positive rates of uPAR and VEGF-C were 69.7 %(23/33) and 78.8 %(26/33) respectively in 33 cases of HCC. The expression rates of uPAR and VEGF-C were significantly higher in HCC with metastasis than in HCC without metastasis(P 〈0.05). But there were not significant correlation between the expression of uPAR or VEGF-C and tumor size, tumor grade, AFP level, hepatic cirrhosis. There was a close correlation between uPAR and VEGF-C in HCC(r =0.676,P 〈0.01). Conclusion The expression of uPAR and VEGF-C is correlated with metastasis, uPAR and VEGF-C may be signs of aggressive phenotype for evaluating treatment and prognosis of HCC. Examination of these two proteins may be helpful to judge biological behavior of HCC.
