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.
