IFNG and head and neck squamous cell carcinoma: In CSCC we found that the expression of the analyzed immune signatures (Expanded immune genes, IFN gamma genes, CTL genes, and HLA genes) were associated with favorable OS in all stages (HR=0.6; 95% CI=0.35–1.04; log rank p=0.068) (Figure 5A and Table 5), showing similar results with that in the of case of HNSCC.
