非小细胞肺癌端粒酶活性表达及其临床意义

目的 :探讨非小细胞肺癌组织端粒酶活性表达及其临床意义。方法 :应用TRAP -PCR -ELISA方法检测36例非小细胞肺癌组织及相应的 32例癌旁组织 ,9例肺良性病变组织和 9例正常肺组织中端粒酶活性表达。结果 :肺癌组织中端粒酶活性表达阳性率为 75 % (2 7/ 36 ) ,癌旁组织为 6 .2 5 % (2 / 32 ) ,肺良性病变组织为 11.1% (1/ 9) ,正常肺组织为 0 % (0 / 9)。肺癌组织端粒酶活性表达与肺癌病理类型、组织分化程度、原发肿瘤大小、淋巴结转移情况及临床分期无明显相关。结论 :端粒酶在肺癌组织中的高表达可作为肺癌诊断和鉴别诊断的重要分子生物学指标之一

Study on telomerase activity and its clinical value in human non small cell lung cancer

Objective To investigate telomerase activity and its clinical value in human non small cell lung cancer. Methods: Using the method of TRAP-PCR-ELISA, we measured telomerase activity in human non small cell lung cancerous, adjacent, lung benign lesion, and normal lung tissues. Results: The positive rate of telomerase activity was 75%(27/36) in lung cancerous tissues; 6.25%(2/32) in adjacent tissues; 11.1%(1/9) in lung benign lesion tissues; and 0%(0/9) in normal lung tissues. There was no significant difference in telomerase activity among the pathological type,the degree of tissue differentiation,the size of tumor, lymph node metastasis, and clinical stage in the patients with lung cancer. Conclusion: The telomerase activity may become an important molecular marker in the diagnosis and differential diagnosis of human non small cell lung cancer.
