Kaplan–Meier analysis of the prognostic value of the CD56+ NK cell/Hsp70 marker combination in FFPE tumor sections of HPV16 DNA‐negative (N = 92) and ‐positive (N = 53) SCCHN patients with overall survival (OS). (a) Significant correlation of infiltrating CD56+ NK cells in tumor sections of HPV16 DNA‐negative SCCHN patients (N = 92) and OS in sections with a low (scores 0–2, p = 0.004) and high (scores 3–4, p = 0.004) Hsp70 expression. Black line represents high and gray lines represent low numbers of infiltrating CD56+ NK cells. (b) No significant correlation of infiltrating CD56+ NK cells in tumor sections of HPV16 DNA‐positive SCCHN patients (N = 53) and OS in sections with a low (scores 0–2) and high (scores 3–4) Hsp70 expression. Black line represents high and gray lines represent low numbers of infiltrating CD56+ NK cells.
