目的:探讨Bmi-1 在非小细胞肺癌(NSCLC)组织中的表达及其与临床病理特征的关系。方法:采用RT-PCR 检测30 例非小
细胞肺癌及20 例癌旁组织中Bmi-1mRNA 的表达情况,同时应用免疫组织化学SP 法检测52 例非小细胞肺癌及30 例癌旁组织
中Bmi-1 蛋白表达情况。结果:非小细胞肺癌组织中Bmi-1mRNA 表达量明显高于癌旁组织(t=5.188,P<0.01)。肺癌组中Bmi-1 蛋
白的阳性表达率为67.3%(35/52),明显高于癌旁组13.3%(4/30),且表达量差别有高度统计学意义(Z=-4.837,P<0.01);肺癌组中
Bmi-1 蛋白阳性表达与癌组织的TNM 分期及有无淋巴结转移有关(Z=-2.567,-2.366, P<0.05),而与患者的性别、年龄、组织类型、
分化程度等无关(P 均>0.05);结论:Bmi-1 在非小细胞肺癌中的高表达与肿瘤发生发展及转移相关,可成为早期诊断肺癌及判断
转移的重要参考指标。 |

Objective: To investigate the relationship between the expression of Bmi-1 in nonsmall-cell lung cancer (NSCLC) and
clinicopathologic characters. Methods: Reverse transcription-PCR(RT-PCR)was applied to detect Bmi-1 mRNA in 30 of NSCLC specimen
and 20 of tumor-adjacent tissue. Immunohistochemistry was performed to detect the expression of Bmi-1 in 52 of NSCLC specimen
and 30 of tumor-adjacent tissue. Results: The expression of Bmi-1mRNA in NSCLC specimen was remarkably higher than that in tumor-
adjacent tissue (t=5.188,P<0.01). The positive rate of Bmi-1 expression was 67.3%(35/52)in NSCLC specimen and 13.3%(4/30)
in tumor-adjacent tissue, respectively. There was a statistically significant difference for the expression of Bmi-1mRNA between NSCLC
specimen and tumor-adjacent tissue (Z=-4.837, P<0.01). Bmi-1 expression in NSCLC was correlated with both TNM staging and lymph
nodemetastasis(Z=-2.567, -2.366, P<0.05), butwhich had no relationshipwith sex, age, histotype and differentiation (P >0.05). Conclusion:
High expression of Bmi-1 in NSCLC is related with the development and metastasis of tumorigenesis. |
