Abstract: The SWI/SNF (SWItch/sucrose non-fermentable) complex is an ATP-dependent chromatin remodeling complex, and its subunits are frequently mutated or lost in hepatocellular carcinoma (HCC). These mutations or losses can lead to abnormal chromatin structure and function, thus affecting the biological behavior of HCC cells and influencing the response to immune checkpoint inhibitors(ICIs)therapy in HCC patients. This review primarily summarizes the research progresses on the subunit mutations of the SWI/SNF complex in HCC and their association with ICIs therapy response. It explores the relationship between subunit mutations, ICIs therapy response rate, drug resistance, and predictive biomarkers, as well as provides insights into future research directions and the clinical application prospects.

Key words: SWI/SNF complex, hepatocellular carcinoma(HCC), immune checkpoint inhibitors, chromatin remodeling
