From: Prognostic significance of tumor infiltrating immune cells in oral squamous cell carcinoma
Correlation between immune cells infiltration and OS of OSCC patients. a, b and c Survival curves were stratified by CD8, CD57 and N stage with the Kaplan-Meier method. High CD8, high CD57 and no lymphnode metastasis were associated with longer survival (p < 0.001). d, e Kaplan-Meier curves illustrate the duration of survival according to the N stages and to the density of CD8+ cells (d) and CD57+ cells (e). CD8 and CD57 expression was associated with survival regardless of N stages (CD8-Lo/No LN metastasis vs. CD8-Hi/No LN metastasis, p < 0.001; CD8-Lo/ LN metastasis vs. CD8-Hi/ LN metastasis, p = 0.002; CD57-Lo/No LN metastasis vs. CD57-Hi/No LN metastasis, p < 0.001; CD57-Lo/ LN metastasis vs. CD57-Hi/ LN metastasis, p < 0.001). Hi, high expression; Lo, low expression; LN, lymphnode
