肿瘤液体活检

肿瘤是危害人类健康的重大疾病,其复杂性和异质性使得肿瘤诊疗进展缓慢。精准医疗促使肿瘤诊疗方式朝着更加精细化、个体化的方向发展,分子诊断技术和靶向治疗正逐步应用于肿瘤临床诊疗过程。液体活检技术能够通过患者体液反映疾病状态,无创且能提供动态丰富的肿瘤相关分子信息,在肿瘤早期预警及辅助诊断、疗效实时监测、用药指导和耐药机制探索、预后判断和风险分级、靶向药物伴随诊断等方面具有巨大应用潜能,受到临床的广泛关注。论文将针对液体活检的分类、临床应用及未来发展等方面,综述液体活检在肿瘤精准诊疗中的最新进展。

Liquid biopsy of tumor

Tumor, whose complexity and heterogeneity make the progress of tumor diagnosis and treatment slow, is damaging human life and health. Precision medicine promotes the development of tumor diagnosis and treatment in a more refined and individual direction, and molecular diagnostic techniques and targeted therapy are gradually being applied in the clinical diagnosis and treatment of tumors. Liquid biopsy can reflect disease status through a patients body fluids. It is noninvasive and able to provide dynamic and rich molecular information, thus, it has great potential in the early detection and auxiliary diagnosis, real time monitoring of treatment efficacy, guidance of drug use and exploration of mechanism in drug resistance, prognosis and risk stratification, and concomitant diagnosis of targeted drugs. This review will focus on the classification, clinical application, as well as future challenges of liquid biopsy in precision oncology and introduce the latest development.
