摘要
目的:研究肺癌组织中p53、p16、nm23基因蛋白的表达。方法:应用免疫组化LSAB方法检测129例肺癌标本中p53、p16、nm23基因蛋白的表达。结果:p53、p16、nm23蛋白在肺癌中的阳性表达率分别为527%、457%、558%;3种蛋白阳性表达率与组织学分型无明显相关(P>005);肺腺癌淋巴结转移阳性组p53蛋白阳性表达率显著高于淋巴结无转移组(P<005);p53蛋白阳性表达组及p16蛋白阴性表达组的预后差(P<005);nm23蛋白表达与患者预后无关。结论:p53、p16蛋白异常表达可做为评估肺癌患者预后的有效指标;未能证实nm23基因在肺癌中具转移抑制功能。
Purpose To study the significance of p53p16 and nm23 protein expression in lung cancer. Methods The expression of the three protein was investigated by LSAB immunohistochemical technique in 129 cases of lung cancer. Results The positivity rates of p53p16 and nm23 protein were 527%,457%,558%,respectively, and the expression was not correlated with histological type; there was a positive correlation between p53 expression and lymph node metastasis in adenocarcinoma; the prognosis of the patients with p53 positive and p16 negative tumor was poor; but no correlation between prognosis and nm23 expression was found. Conclusion The change of p53p16 and nm23 gene is correlated with progression of lung cancer; the expression of p53 and p16 has an important effect on predicting the prognosis of lung cancer; nm23 gene has no antimetastastatic function in lung cancer.
