Abstract
Gastric cancer is a malignant tumor with high morbidity and mortality, which is a serious threat to human life and health. At present, the diagnosis and course monitoring of gastric cancer mainly rely on gastroscopic biopsy and CT, but their invasiveness and delay limit their clinical value. Gastric cancer patients urgently need a real-time, accurate, non-invasive diagnosis and course monitoring method. Circulating tumor DNA(ctDNA) is single or double stranded DNA released into body fluid by tumor cells, which contains the same genetic mutations as the original tumor cells. It is also one of the newly emerged biological markers. With the emergence and development of next-generation sequencing(NGS) technology, the sensitivity and specificity of ctDNA detection continue to increase, and it is gradually becoming a new choice for tumor diagnosis and disease course monitoring. In this paper, the current application of the next-generation sequencing technology detecting ctDNA in diagnosis and treatment of gastric cancer was discussed.
