Core Tip

Core tip: Although chemotherapy remains one of the primary therapeutic modalities used in the treatment of gastric cancer, chemoresistance limits the effectiveness of chemotherapy and results in treatment failure. The elucidation of the mechanisms of drug resistance will be very helpful for the prediction of sensitivity to chemotherapy and the reversal of drug resistance to improve therapeutic efficacy. The mechanisms of drug resistance have been broadly investigated in recent years. In this review, we summarize the molecular mechanisms of chemoresistance in gastric cancer and discuss the progress in the reversal of drug resistance.
