摘要
肺癌是世界上最致命的癌症类型。仅仅在美国，每年就有超过225000人被确诊为肺癌，2012年预计死于肺癌的患者大约有16万。与癌胚抗原(carcinoembryonic antigen，CEA)在结肠癌以及前列腺特异抗原(prostate specific antigen，PSA)在前列腺癌中的作用不同，在肺癌患者诊治过程中，肿瘤标志物的应用并不广泛。肺癌的诊断依赖于影像学检查，而不是体液中的肿瘤标志物。然而在最近的研究中，循环肿瘤细胞(circulating tumor cells，CTCs)的潜在价值被发现。基于CTCs的分析已经被视作“液相活组织检查”，它将有助于我们对恶性肿瘤进行定性和定量的分析

Abstract
Circulating tumor cells (CTCs) are associated with survival of cancer patients. Several methods have been developed to detect circulating tumor cells. The number of CTCs in NSCLC is lower than in other solid tumors. To date, trials are ongoing for a better understanding of CTCs. Besides association with prognosis, CTCs can be used to assess the efficacy of treatment and they are important substrates for molecular profiling of the tumor.
