目的 检测非小细胞肺癌(NSCLC)组织子途径抑制物-2(TFPI-2)基胞嘧啶-磷酸-鸟嘌呤基序(CpG)岛甲基化的状态,探讨甲基化状态与非小细胞肺癌发生发展及浸润转移的关系.方法 应用甲基化特异性聚合酶链反应(MS-PCR)检测60例非小细胞肺癌组织及相应癌旁组织和10例正常肺组织的TFPI-2基因甲基化状态.结果 非小细胞肺癌组织中TFPI-2基因的甲基化阳性率为38.3% (23/60),明显高于癌旁组织的6.7% (4/60)(P<0.01).10例正常肺组织中均未发生甲基化.临床分期为Ⅰ、Ⅱ、Ⅲ期的患者中TFPI-2基因甲基化阳性率分别为18.2%、53.8%、66.7% (P<0.01),肿瘤直径>5 cm和≤5 cm的患者中TFPI-2基六因甲基化阳性率分别为80.0%、17.5%(P<0.01),无淋巴结转移和有淋巴结转移的患者中TFPI-2基因甲基化阳性率分别为25.6%、61.9%(P<0.01).结论 TFPI-2基因在非小细胞肺癌组织中出现异常甲基化,且与临床分期、肿瘤大小及淋巴结是否转移密切相关.

Objective To investigate the methvlation of Cytosine-phosphoric acid-guanine motif (CpG) island of tissue factor pathway inhibitor 2 (TFPI-2) gene in non-small cell long cancer (NSCLC)and the relationship between the aberrant methylation of CpG islaud of TFPI-2 gene and the occurrence,progression,invasion and metastasis of NSCLC.Methods Methylation specific PCR was used to detect the promoter methylation of TFPI-2 gene in cancer tissues from 60 patients with NSCLC and normal lung tissues from 10 patients with pulmonary bullae.Results Promoter methylation of TFPI-2 gene was found in 38.3% (23/60) of NSCLC tissuees and 6.7% (4/60) of carcinoma adjacent tissues respectively (P <0.01).Aberrant methylation was not found in 10 normal lung tissues.TFPI-2 gene methylation positive rate was 18.2%,53.8% and 66.7% in the patients with NSCLC of clinical stage Ⅰ,Ⅱ,Ⅲ (P<0.01),that was 80.0% and 17.5% in tumor diameter > 5 cmand ≤ 5 cm (P<0.01),and that was 25.6% and 61.9% in patients without lymph node metastasis and lymph node metastasis (P < 0.01).Conclusion Aberrant methvlation of TFPI-2 gene was found in NSCLC,which may be associated with the clinical stage,tumor size,and lymph node metastasis.
