An Immunogenic Cell Death-Related Classification Predicts Prognosis and Response to Immunotherapy in Hepatocellular carcinoma
Research Square (Research Square)(2022)
摘要
Abstract Hepatocellular carcinoma (HCC) is one of the world's malignant tumors with high mortality and a worse prognosis. Immunogenic cell death is caused by tumor cells stimulated by stressors to display or release Danger Associated Molecular Patterns (DAMPs)that attract and activate antigen-presenting cells. It would be advantageous to identify biomarkers associated with Immunogenic cell death(ICD) and stratify patients according to their benefits from ICD immunotherapy. Here, we identified two subtypes ICD-related by consensus clustering. ICD-high Subtype has an excellent clinical outcome, abundant immune cell infiltration, and highly active immune response signaling. In addition, we developed and validated an ICD-related risk model that predicts HCC patients' survival and correlates with the tumor immune microenvironment. In conclusion, we have established a new classification system for HCC based on ICD signatures. This stratification has significant clinical outcomes for estimating prognosis and immunotherapy in HCC patients.
