Abstract
Comprehensive analysis of ferroptosis in Hepatocellular Carcinoma (HCC) and its relation to the tumor immune microenvironment are needed. Data included HCC in The Cancer Genome Atlas and International Cancer Genome Consortium. And two datasets from Gene Expression Omnibus (GEO) were used as the validation set. Based on the expression of ferroptosis-related genes, HCC patients were divided into two subtypes. Cluster 1 showed lower tumor grade, lower CTLA-4, and a more favorable prognosis than Cluster 2. Patients with higher SLC7A11 (50%) had a poorer prognosis in HCC. SLC7A11 is characterized by more NK CD56bright cells, less DC, and neuroactive ligand-receptor interaction and cytokine receptor interaction. Ferroptosis-related genes especially SLC7A11 might be a valuable prognostic factor in HCC.
