Abstract

肺癌是我国发病率最高的癌症,也是癌症患者死亡的首要病因。其中,约85%是非小细胞肺癌(non-small cell lung cancer, NSCLC)。肺癌患者的诊断方法和治疗措施一直是重中之重。近年来,随着分子生物学检测技术的快速进步以及精准治疗和个体化治疗的发展,液体活检因其具有传统侵入性活检所不具备的优点而成为关注的焦点,如安全、便捷、重复性、低创伤性等。液体活检作为一种新兴技术,其检测对象主要包括外周血中的循环肿瘤DNA(circulating tumor DNA, ctDNA)、循环肿瘤细胞(circulating tumor cells, CTCs)、外泌体等。本文将对ctDNA、CTCs和外泌体的检测及其在NSCLC患者中的临床应用作一简要综述。
