FLI1 and nasopharyngeal carcinoma: In addition, Kaplan-Meier survival analysis showed that NPC patients with high FLI1 expression levels had a remarkably shorter overall survival (OS, p = 0.030), local recurrence free survival (LRFS, p = 0.010) and progress free survival (PFS, p = 0.021) (Fig. 1C–E).
