ObjectiveTo summarize the research progress of hepatocellular carcinoma (HCC) based on tumor microenvironment immunophenotyping.MethodThe related literatures of basic and clinical studies on HCC immunophenotyping in the recent years were reviewed.ResultsHCC could be divided into different immunophenotypes based on tumor microenvironment, and it showed different immune molecular characteristics, immune cell infiltration characteristics, and anti-tumor ability. At the same time, the HCC immunophenotype was significantly associated with patients’ survival and had been proved to be able to better evaluate the prognosis of HCC patients. According to the relevant molecular characteristics in the HCC immune microenvironment, it could provide guidance for the drug regimen of immunotherapy.ConclusionHCC immunophenotyping is still in the early stage of research, and its clinical application value has been preliminarily shown for the evaluation of patients’ prognosis and immunotherapy decision-making, which is a new idea of individualized treatment of HCC in the future.
