目的揭示重庆地区肝癌患者HBV和/或HCV的感染与癌组织中癌基因和抑癌基因表达之间的联系。方法应用免疫组织化学方法检测 HBV和 HCV抗原以诊断 HBV和 HCV感染,癌基因 ras、c-myc、c-erbB-2和抑癌基因 p53蛋白的表达也用免疫组化方法检测。结果 46例肝癌患者中,HBV感染34例,HCV感染20例;其癌组织中ras p21、c-myc、c-erbB-2和p53蛋白表达阳性率分别为 58.7%、67.4%、47.8%和 30.4%,HCV双重感染14例,单独 HBV感染 20例,单独 HCV感染 6例,无 HBV、HCV感染 6例;四组不同 HBV、HCV感染状况肝癌组织中rasp21、c-myc、c-erbB-2和 p53蛋白表达阳性率无显著差异( P>0.05)。结论 HBV、HCV感染可能与原发性肝癌发生密切相关,HBV、HCV的不同感染状况与癌基因ras、c一myc、c-erbB-2和抑癌基因p53蛋白表达之间的联系并不明显。
Objective To reveal the association between HBV and / or HCV infection in hepatocellular carcinoma patients and the expression of oncogenes and tumor suppressor genes in cancer tissues in Chongqing area. Methods The HBV and HCV antigens were detected by immunohistochemistry in order to diagnose HBV and HCV infection. The expressions of oncogenes ras, c-myc, c-erbB-2 and tumor suppressor gene p53 protein were also detected by immunohistochemistry. Results The positive rate of ras p21, c-myc, c-erbB-2 and p53 protein expression in cancer tissues was 58.7% and 67.4% respectively in 34 cases of hepatocellular carcinoma and in 20 cases of HCV infection. , 47.8% and 30.4% respectively. There were 14 cases of HCV double infection, 20 cases of HBV infection alone, 6 cases of HCV infection alone, 6 cases without HBV and HCV infection. The positive rates of c-myc, c-erbB-2 and p53 were not significantly different (P> 0.05). Conclusions HBV and HCV infection may be closely related to the occurrence of primary hepatocellular carcinoma. The relationship between different infection states of HBV and HCV and the expression of oncogenes ras, c-myc, c-erbB-2 and tumor suppressor gene p53 protein is not obvious .
