Abstract
BackgroundGlobally, hepatocellular carcinoma (HCC) is one of the most prevalent and deadly malignant tumors. A recent study proposed disulfidptosis, a novel form of regulated cell death (RCD), offering a new avenue for identifying tumor prognosis biomarkers and developing novel therapeutic targets.MethodsBased on the expression data of 14 disulfideptosis-related genes extracted from public databases, a new molecular classification of HCC called the “disulfidptosis score” was constructed and its relationship to tumor immunity and prognosis was evaluated.ResultsBased on the expression of disulfideptosis-related genes, we performed cluster analysis on HCC samples from the TCGA cohort, which classified these patients into three clusters: A, B, and C, and the differentially expressed genes of different clusters were analyzed. A disulfidptosis score model was constructed by differentially expressed genes associated with prognosis. Univariate and multivariate COX regression analysis showed that disulfidptosis score was an independent prognostic factor for HCC. In addition, in various disulfidptosis score groups, notable disparities were observed concerning the tumor immune microenvironment as well as the expression of immune checkpoint.ConclusionDisulfidptosis score have an important role in predicting HCC prognosis and help guide us in providing better immunotherapy options for patients.
