Abstract: Immunotherapy improves the overall treatment strategy of liver cancer. Its unique immune heterogeneity and high tolerance to immune microenvironment make immunotherapy enter the bottleneck stage.Therefore,it is necessary to classify molecular classifications of liver cancer patients who may benefit from immune checkpoint therapy.With the progress of next-generation sequencing technology,scientists have explored molecular classifications based on the abundance of infiltrating immune cells,the expression of immune checkpoints,multi-omics data,mutually exclusive mechanisms for immunosuppression and the heterogeneity of tumor microenvironment.It is not only the specific biological,molecular and clinicopathological characteristics of liver cancer associated with the tumor microenvironment,but it also shows the overlap with the molecular classifications of the transcriptome.It is beneficial to the diagnosis of liver cancer,the choice of treatment methods and the prediction of clinical outcomes,and promotes accurate individualized immunotherapy for liver cancer.

Key words: Hepatocellular carcinoma, Tumor immunological microenvironment, Molecular classifications, Immune checkpoint inhibitor
