Ferroptosis Markers Predict the Survival, Immune Infiltration, and Ibrutinib Resistance of Diffuse Large B cell Lymphoma

Diffuse large B cell lymphoma (DLBCL) is the most common hematological malignancy in adults. Ferroptosis is an iron-dependent programmed cell death caused by lipid peroxidation. However, the potential functions of ferroptosis in the DLBCL prognosis, immune infiltration, and drug resistance remain un...

Zusammenfassung:Diffuse large B cell lymphoma (DLBCL) is the most common hematological malignancy in adults. Ferroptosis is an iron-dependent programmed cell death caused by lipid peroxidation. However, the potential functions of ferroptosis in the DLBCL prognosis, immune infiltration, and drug resistance remain unknown. Data of DLBCL patients were downloaded from public GEO databases and TCGA cohort. R software was used for analysis. Ferroptosis-related risk score model was constructed using LASSO Cox regression analysis. The prognosis of the model and its association with immune cells infiltration and ibrutinib-resistance were studied by single-sample gene set enrichment analysis (ssGSEA) and correlation analysis. Ferroptosis-related risk score model was constructed with 11 ferroptosis-related genes. DLBCL patients can be divided into high- or low-risk groups with this model. High-risk patients had significant shorter survival ( p
