High IL-8 expression correlates with shorter overall survival, disease-free survival, and distant-metastasis-free survival in patients with NPC. (A) Tissue microarrays representative of those from 255 patients with NPC diagnosed at the M0 stage immunohistochemically stained using antibody against IL-8, at low (40×) and high (400×) magnification in a light microscope. Black scale bars0 500 µm; yellow scale bars, 100 µm. (B) The median follow-up time of these 255 patients was 69 months. (C) Overall survival (OS) curve. (D) Disease-free survival (DFS) curve. (E) Distant-metastasis-free survival (DMFS) curve. P values were calculated by the log-rank test.
