Abstract： 目的 研究根治性化放疗的非小细胞肺癌(NSCLC)患者放疗前以CK19 mRNA表达为标志的外周血微转移的临床意义.方法 应用巢式RT-PCR方法,检测106例NSCLC患者根治性化放疗前外周血微转移标志物CK19 mRNA的表达,并研究其与临床病理特征相关性和预后意义.结果 外周血微转移阳性率为63%(67/106).外周血微转移与N分期(χ=10.41,P=0.001)、病理类型(χ2=5.22,P=0.022)和病理分级相关(χ2=7.82,P=0.020),但与性别(χ2=2.70,P=0.100)、T分期(χ2=0.01,P=0.941)、TNM分期(χ2=5.32,P=0.070)、体重减轻(χ2=0.71,P=0.399)和KPS评分(χ2=0.23,P=0.629)无相关性.外周血微转移阳性和阴性3年远处转移率分别为70%和63%(χ2=0.34,P=0.559);3年局部复发率分别为69%和57%(χ2=0.61,P=0.435);所有患者中位生存期和3年总生存率分别为17个月和24%;外周血微转移阳性和阴性中位生存期分别为16、20个月,3年总生存率分别为21%和28%(χ2=0.61,P=0.435).结论 NSCLC根治性化放疗前外周血微转移与N分期、病理类型和病理分级密切相关,但无预后意义.
