摘要：

Gastric cancer is the fourth most common cancer and the second leading cause of cancer deaths worldwide.Chemotherapy is one of the major treatments for gastric cancer,but drug resistance limits the effectiveness of chemotherapy,which results in treatment failure.Resistance to chemotherapy can be present intrinsically before the administration of chemotherapy or it can develop during chemotherapy.The mechanisms of chemotherapy resistance in gastric cancer are complex and multifactorial.A variety of factors have been demonstrated to be involved in chemoresistance,including the reduced intracellular concentrations of drugs,alterations in drug targets,the dysregulation of cell survival and death signaling pathways,and interactions between cancer cells and the tumor microenvironment.This review focuses on the molecular mechanisms of chemoresistance in gastric cancer and on recent studies that have sought to overcome the underlying mechanisms of chemoresistance.
