Abstract: Gut microbes are an “ecosystem” closely related to body health.On the one hand,intestinal microbes can provide nutrients for the body,participate in the body's metabolism and immune regulation,resist pathogens,and exert biological barrier functions.On the other hand,intestinal microbes and their metabolites can participate in the occurrence of colorectal cancer,regulate the mechanism of chemotherapy drugs and immune checkpoint inhibitors,then affect the efficacy of chemotherapy and immunotherapy,and regulate related adverse reactions.Based on a large number of previous studies on intestinal microbes and related literatures,this article will review the current status of intestinal microbes affecting the mechanism and efficacy of chemotherapy drugs for colorectal cancer,which is expected to be a new target for improving the treatment of colorectal cancer and reducing the side reaction of the drug toxicity.

Key words: Gut microbes, Colorectal cancer, Mechanism of drug action, Efficacy
