Survival curves of locally advanced NPC patients with different GTV-P and T categories. Patients with different GTV-P had significant differences in overall survival (OS) (a), local relapse-free survival (LRFS) (b), distant metastasis-free survival (DMFS) (c), and disease-free survival (DFS) (d). Patients with different T categories were not different in OS (e) or LRFS (f), but had significant differences in DMFS (g) and DFS (h). T3 tumors were subclassified as T3V1 (T3 tumors with GTV-P ≤46.4 mL) and T3V2 tumors (T3 tumors with GTV-P >46.4 mL); T4 tumors were subclassified as T4V1 (T4 tumors with GTV-P ≤46.4 mL) and T4V2 tumors (T4 tumors with GTV-P >46.4 mL). Significant differences in OS (i), LRFS (j), DMFS (k), and DFS (l) were observed between patients with T4V1 and T4V2 tumors, but not between patients with T3V1 and T3V2 tumors
