FLI1 expression is positively correlated with TIE1 expression and high FLI1-TIE1 levels predict poor clinical outcomes in NPC patients. A Representative images of IHC staining of TIE1 protein expression in 137 NPC tissues (a, no brown particle staining; b, light brown particles; c, moderate brown particles; d, dark brown particles). Scale bars = 100 μm. B–D Kaplan–Meier analysis of the overall survival B, local recurrence free survival C and progress free survival D of 137 NPC patients based on TIE1 expression. The p values were analyzed by log-rank test. E The correlation analysis between FLI1 expression and TIE1 expression. Pearson chi-square analysis was used to determine the correlation
