Abstract: Cancer is a major disease that seriously endangers human health.In recent years,immune checkpoint inhibitors(ICIs)have changed the paradigm of treatment for various solid tumors.Although the initial treatment effect is significant,the issue of drug resistance in this therapy has gradually become apparent.It is particularly important to have a deep understanding of the mechanisms of ICIs resistance.Neutrophils in the tumor microenvironment(TME)play a critical role in the resistance of programmed cell death protein-1(PD-1)and its ligand inhibitors.Thus,remodeling tumor-associated neutrophils(TANs)can not only enhance the anti-tumor immune response,but also contribute to improving patient prognosis.This article aims to explore the potential role of TANs in ICIs resistance and summarize current efforts to overcome ICIs resistance.

Key words: Tumor-associated neutrophils, Immune checkpoint inhibitors, Drug resistance
