Positive correlations were observed between the abundance of LMP1 and GLUT1 in malignant cells and the number of CD33⁺ MDSCs in NPC tissues.

<p>(<b>A</b>) Representative IHC staining for LMP1 and GLUT1 in NPC specimens. (<b>B-D</b>) Statistical analyses of the correlations between LMP1 expression and CD33^<b>+</b> MDSC number (<b>B</b>), GLUT1 expression and CD33^<b>+</b> MDSC number (<b>C</b>), and LMP1 and GLUT1 expression level (<b>D</b>), Pearson’s chi-square test was used to assess statistical significance. (<b>E-F</b>) Kaplan-Meier estimates of the progression-free interval were determined based on the median levels of LMP1 (<b>E</b>) and GLUT1 (<b>F</b>) in the patients with NPC. P < 0.05 was considered statistically significant.
