Gene set enrichment analysis. Cancer-related signaling pathways were enriched in the high-risk group, including (A) pathways in cancer, (B) MAPK signaling pathway, (C) VEGF signaling pathway, (D) mTOR signaling pathway, and (E) JAK signaling pathway. (F) Ferroptosis-related signaling pathways were enriched in the high-risk group, including (F) glutathione metabolism. All P < 0.05, FDR<0.25.
