MAGE-10基因在肝细胞肝癌中的表达及临床意义

Expression of MAGE-10 genes in human hepatocellular carcinoma and its clinical significance

目的 探讨MAGE - 10基因与肝细胞肝癌 (HCC)患者临床指标及转移复发的关系。 方法 用RT -PCR的方法测定 31例HCC癌组织及相应癌旁组织和 10例肝硬化组织MAGE - 10基因表达 ,对全部RT -PCR扩增产物中目的基因片段进行DNA测序以证实其为MAGE - 10基因 ,31例HCC测定AFP、岩藻糖苷酶 (AFU)、抗HCV、HBsAg、AFPmRNA、肿瘤直径等临床指标。 结果 31例HCC组织中MAGE - 10基因表达的阳性率为 5 1 6 % (16 / 31) ,明显高于癌旁组织 0 % (0 / 31) ,(χ2 =18 95 ,P <0 0 1)。HCC组织中MAGE - 10基因表达的阳性率与血清AFP、AFU、抗HCV、HBsAg、AFPmRNA水平及肿瘤大小无关 (P >0 0 5 )。 10例肝硬化组织中未见MAGE - 10基因的表达。 结论 MAGE - 10基因在HCC组织中特异高表达 ,其阳性率与HCC患者肿瘤标志物无关。

Objective To study the relationship between the expression of MAGE-10 genes and the clinical parameters of metastasis and recurrence of patients with Hepatocellular carainama (HCC). Methods The expression of MAGE-10 genes in tumor tissues,liver tissues adjacent to tumor and hepatocirrhosis tissues was examined by RT-PCR method.The relationship between positive expression rate of MAGE-10 genes and clinical parameters of metastasis and recurrence (such as AFP, AFU, Anti-HCV, HBsAg, AFPmRNA, diameter of tumor) in patients with HCC were studied. Results The positive expression rate of MAGE-10 genes significantly higher in tumor tissues than that in the surrounding tumor tissues (51 6% vs. 0%, χ 2=18 95,P <0 01). There was no relationship between the positive expression rate of MAGE-10 gene and tumor marker ( P >0 05).There was no expression of MAGE-10 in hepatocirrhosis tissues of 10 cases. Conclusions There was a high frequency of MAGE-10 genes expression in HCC,but it is unrelated to the tumor markers,metastasis and recurrence of HCC.
