Abstract:
Circulating tumor DNA(ctDNA) is the DNA fragment released into blood by tumor cells.Wheather it presents or not and its plasma concentration are closely related to the prognosis of patients. The common detection methods of ctDNA include digital polymerase chain reaction,second-generation sequencing,methylation detection technology and so on. Detecting specific point mutations or methylation of ctDNA can not only assist in the diagnosis of pancreatic cancer,but also be expected to identify pancreatic cancer at an early stage. Detecting ctDNA after operation can help predicting tumor recurrence and metastasis effectively,so that patients with high recurrence and metastasis risks can be intervened in advance. Accordingly,this article intends to review detection technology of ctDNA and its clinical applications in the early diagnosis of pancreatic cancer,the prediction of tumor recurrence and metastasis after surgery,and the evaluation of patient prognosis.
