摘要
目的:探讨肺腺癌原发灶及其淋巴结转移灶中凋亡相关基因bcl-2及p53的表达意义,为进行肺腺癌的分子生物学研究提供理论依据。方法:采用免疫组化S-P法,用抗bcl-2单克隆抗体及抗p53单克隆抗体分别对63例发生淋巴结转移的肺腺癌组织及其相应淋巴结进行标记分析,且按性别、年龄、分化程度、TNM分期等进行分组比较。结果:bcl-2与肺腺癌淋巴结转移、患者性别、年龄、分化程度无关(P〉0.05),TNM分期Ⅰ~Ⅱ期肺腺癌bcl-2阳性率大于Ⅲ~Ⅳ期肺腺癌,差异具有显著性(P〈0.05);p53与肺腺癌淋巴结转移、患者性别、年龄无关(P〉0.05),与分化程度有关(P〈0.05),TNM分期肺腺癌p53阳性率Ⅲ~Ⅳ期高于Ⅰ~Ⅱ期肺腺癌,差异具有显著性(P〈0.05)。结论:bcl-2及p53在肺腺癌发生发展过程中可能起一定作用.可作为评估肺腺癌预后的生物学指标。
Objective:To investigate the significance of the expression of bcl - 2 and p53 in lung adenocarcinoma and lymph node metastasis. Method:The expression of bcl- 2 and p53 in 63 cases of lung adenocarcinoma with lymph node metastasis were analysed byimmunohistochemical SP method using monoclonal antibody to bcl- 2 and monoclonal antibody to p53. Results:bcl- 2 was not related to lymph node metastasis, patients' sex, age and differentiation in lung adenocarcinoma(P 〉 0.05):the positive rate of bcl- 2 was higher in TNM stage Ⅰ~Ⅱ than in stage Ⅲ-Ⅳ (P〈 0.05) ;p53 was not related to lymph node metastasis, patients'sex, age in lung adenocarcinoma(P〈 0.05). p53 was correlated with differentiation(P (0.05). The positve rate of p53 was higher in TNM stage Ⅲ~Ⅳ than in stage Ⅰ~Ⅱ (P〈0.05). Conclusions:bcl- 2 and p53 may play role in the carcinogenesis of lung adenocarcinoma. They can be valuable in predicting the prognosis of lung adenocarcinoma.
