Abstract The number of parasitic bacteria in the human intestinal tract reached 1014， more than 10 times the number of human cells， including symbiosis and pathogenic microorganisms， which jointly formed the microbial ecological community， namely the intestinal microecology. The intestinal tract provides a place for the growth and reproduction of microorganisms， while microorganisms provide the host with enzymes and biotransformation pathways that are not available in the human body. Therefore， they can decompose the polysaccharide oligosaccharide glycoprotein that is not easily digested by the human body， generate short-chain fatty acids， provide energy for the host， and provide nutrients for the growth and reproduction of intestinal flora. Secondly， intestinal microorganisms produce effects through co-metabolism with the host. For example， multiple metabolic pathways， such as fat emulsification， cholesterol absorption， and enterohepatic circulation， are involved in the catabolism of drugs and other foreign compounds. In addition， intestinal microorganisms form barrier effects against pathogenic microorganisms through their own surface antigens and the host immune system. There is increasing evidence that intestinal microecology plays an important role in the process of tumorigenesis， development and treatment， and has extensive connections with the host. So far， some achievements have been made in the treatment of intestinal microecology intervention with certain means. With the deepening of the research on the relationship between intestinal microecology and tumor， valuable discoveries and inspirations keep emerging. Further exploration and excavation are helpful to improve the understanding of intestinal microecology， hoping to provide more feasible solutions for anti-tumor treatment. This article reviews the advances in clinical outcomes of malignant tumors and intestinal microecology.
