摘要: 基于循环肿瘤细胞(Circulating tumor cells,CTCs)和游离核酸的液体活检技术,在恶性肿瘤的诊断到随访的整个过程中都有潜在的应用价值。与传统组织活检相比,循环肿瘤DNA(Circulating tumor DNA,ctDNA)检测的优势在于风险小,可以进行连续检测,可以监测疾病的复发和随着时间推移对治疗的反应。ctDNA检测的灵敏度取决于使用的检测技术和遗传平台,还受肿瘤部位、分期、肿瘤异质性、肿瘤克隆性等的影响。ctDNA在肾细胞癌(Renal cell carcinoma,RCC)的治疗选择、耐药监测、对依维莫司的治疗反应预测等方面也得到很好的应用。本文主要对ctDNA在肾癌中的研究现状及挑战进行综述。

Abstract: Liquid biopsy technology based on circulating tumor cells(CTCs)and free nucleic acids has a potential application value in the whole process from malignant tumor diagnosis to follow-up.Compared with traditional tissue biopsy,the advantages of circulating tumor DNA(ctDNA)testing is that it has low risk,can be continuously tested,and can monitor the recurrence of the disease and the response to treatment over time.The sensitivity of ctDNA detection depends on the detection technology and genetic platform used,and is also affected by tumor location,staging,tumor heterogeneity,and tumor clonality.ctDNA has also been well applied in the treatment selection of renal cell carcinoma(RCC),drug resistance monitoring,and prediction of response to everolimus treatment.This article mainly reviews the current research status and challenges of ctDNA in renal cancer.

Key words: Renal cell carcinoma, Circulating tumor DNA, Circulating tumor cells, Liquid biopsy
