Abstract
Drug resistance of gastric cancer cells is one of the main reasons that lead to failure of chemotherapy in gastric cancer. Gastric cancer cells can be resistant to chemotherapeutic drugs and targeted drugs, which leads to poor therapeutic effects. Although the mechanisms of drug resistance of gastric cancer cells have long been investigated, no effective drug that can reverse the drug resistance of gastric cancer cells has been found. Therefore, it is important to reverse the drug resistance of gastric cancer cells to improve the prognosis of gastric cancer. In this paper, we review the mechanisms of drug resistance of gastric cancer cells to chemotherapeutic drugs and targeted drugs, summarize current situation for research of drug resistance of gastric cancer cells, and discuss the future development direction in this field.
