非小细胞肺癌外周血Lunx mRNA检测及其对微转移诊断和预后判断的意义

目的:检测非小细胞肺癌(non-small cell lung cancer,NSCLC)患者外周血Lunx mRNA表达,探讨其诊断NSCLC微转移、评估预后和化疗疗效的价值。方法:荧光定量PCR法测定66例NSCLC患者和40例良性肺疾病患者外周血Lunx mRNA表达。肺癌组患者随访1~40个月,了解Lunx mRNA表达与生存期的关系,并对其中50例Ⅲ~Ⅳ期NSCLC患者化疗2周期后进行疗效评价以了解其与Lunx基因表达的关系。结果:肺癌患者外周血Lunx mRNA阳性率为57.6%,中位拷贝数为48 copies/ml;良性肺疾病中则无表达。Ⅲ、Ⅳ期肺癌患者外周血Lunx mRNA阳性率(59.3%,88.9%)均明显高于Ⅰ~Ⅱ期患者(18.8%)(P<0.01),Lunx mRNA阳性表达的患者总体生存期明显低于阴性表达者(P<0.01),但其表达与化疗疗效则无明显关系(P>0.05)。结论:外周血Lunx mRNA表达对判断肺癌患者预后具有较大的价值。

Detection of Lunx mRNA in peripheral blood of non-small cell lung cancer and its for diagnosis of micrometastasis and cancer and prediction of prognosis

Objective:To study the value of the expression of Lunx mRNA in the peripheral blood in detecting the micrometastasis in patients with non-small cell lung cancer(NSCLC)and assessing the prognosis and efficacy of chemotherapy.Methods:Fluorescence quantitative polymerase chain reaction(PCR) was used to detect the expression of Lunx mRNA in the peripheral blood samples from 66 patients with NSCLC and 40 patients with benign pulmonary lesions.The NSCLC patients the cases were followed up for 1 to 40 months,and t...
