Kaplan-Meier survival curves of β-catenin, TCF-4 and survivin for OS, DMFS, LRFS and DFS conditions of NPC patients. a OS of NPC patients with β-catenin expression; b OS of NPC patients with TCF-4 expression; c OS of NPC patients with survivin expression; d DMFS rates of NPC patients with β-catenin expression; e DMFS rates of NPC patients with TCF-4 expression; f DMFS rates of NPC patients with survivin expression; g LRFS rates of NPC patients with β-catenin expression; h LRFS rates of NPC patients with TCF-4 expression; i LRFS rates of NPC patients with survivin expression; j DFS rates of NPC patients with β-catenin expression; k DFS rates of NPC patients with TCF-4 expression; l DFS rates of NPC patients with survivin expression; TCF-4 T-cell factor-4, NPC nasopharyngeal carcinoma, OS overall survival, DMFS distant metastasis-free survival, LRFS local recurrence-free survival, DFS disease-free survival
