Abstract: Gut microbiota is the general term for microorganisms that live in the intestine.The microbiota is affected by many factors such as the host's diet and drugs.At the same time, the microbiota can also participate in the regulation of the host's immune status.At present, some studies have confirmed that the intestinal flora is related to the efficacy and adverse reactions of anti-tumor immunotherapy, and regulating the flora can improve the efficacy of immunotherapy, but the specific mechanism is still unclear.This article systematically reviews the current research progress and shortcomings of gut microbiota and tumor immunotherapy.

Key words: Intestinal flora, Immunotherapy, Fecal microbiota transplantation
