Kaplan-Meier DFS (3A), OS (3B), RRFS (3C) and DMFS (3D) curves for 399 patients with NPC receiving IMRT stratified as the CR, PR and SD groups based on the regional tumour response after induction chemotherapy. Abbreviations: DFS = disease-free survival; OS = overall survival; RRFS = regional relapse-free survival; DMFS = distant metastasis-free survival. CR = complete response; PR = partial response; SD = stable disease.
