The major prognostic pathways in head and neck squamous cell carcinoma (HNSCC) identified by gene set variation analysis (GSVA). (A) Differences in pathway activities scored per sample by GSVA between paired tumor and normal HNSCC in The Cancer Genome Atlas (TCGA) (n = 44). Shown are t-values from a linear model, corrected for patient of origin. dn, down; UV, ultraviolet; v1, version 1; v2, version 2. (B) Univariate Cox regression analysis among various hallmarks of cancer. Kaplan–Meier curves of overall (C) and progression-free (D) survival for HNSCC patients in the two groups divided by GSVA pathway score.
