摘要 目的观察非小细胞肺癌(NSCLC)组织与外周血中异质性胞核核糖核蛋白A2/B1(hnRNP A2/B1)mR-NA表达变化,并探讨其临床意义。方法采用RT-PCR法检测57例NSCLC患者(肺癌组)癌组织与外周血单个核细胞中的hnRNP A2/B1 mRNA,以30例肺部良性病变患者(良性组)为对照。结果肺癌组癌组织与外周血单个核细胞中hnRNP A2/B1 mRNA分别为(0.82±0.49)、(0.69±0.48)μg/μL,良性组分别为(0.16±0.25)、(0.13±0.20)μg/μL;两组比较,P均<0.05。NSCLC患者TNM分期Ⅰ~Ⅱ期者癌组织与外周血单个核细胞中hnRNP A2/B1 mRNA分别为(0.68±0.45)、(0.57±0.47)μg/μL,均低于Ⅲ~Ⅳ期的(0.93±0.49)、(0.78±0.4)μg/μL,P均<0.05。NSCLC患者癌组织与外周血单个核细胞中hnRNP A2/B1 mRNA的表达呈正相关(r=0.941,P<0.05)。结论 NSCLC患者癌组织与外周血单个核细胞中hnRNP A2/B1 mRNA表达增加,且二者呈正相关关系;外周血单个核细胞hnRNP A2/BmRNA检测有助于NSCLC的诊断及病理分期。
