Associations of clinical covariates and HLA-A*02 and HLA-C*04 with progression-free and overall survival. Kaplan–Meier curves of (a,b) localization, (c,d) UICC stage, (e,f) HLA-A*02, and (g,h) HLA-C*04 visualize nonparametric survival analysis. HYPO—hypopharynx; LAR—larynx; NC/PNS—nasal cavity/paranasal sinuses; ORO—oropharynx; p values in the graphs depict the univariate/multivariate Cox PH model results.
