Abstract:Liquid biopsy is a new molecular detection method in recent years, which can help clinicians screen and detect cancer earlier. It offers an alternative method with higher sensitivity and specificity than conventional tumor markers for early diagnosis of tumors. At the same time, liquid biopsy can also monitor the therapeutic efficacy in real time and the production of resistant genes in the tumor and evaluate the risk for metastatic relapse. It has an important clinical application prospect in the individualized and precise treatment of tumors. The biological characteristics of liquid biopsy and its clinical application in gastrointestinal cancer are reviewed in this article.
