Abstract
Background: To investigate the toxicity, changes of quality of life (QOL), and survival for patients with nasopharyngeal cancer (NPC) treated by concurrent chemoradiotherapy (CCRT) with simultaneously integrated boost volumetric-modulated arc therapy (SIB-VMAT). Methods: A total of 68 NPC patients treated by CCRT with SIB-VMAT technique were collected. QOL was longitudinally assessed by the EORTC QLQ-C30 and HN35 questionnaires at the 4 time points: baseline, 42.4 Gy (20 fractions), and 3, 12 months after CCRT. Results: The 4-year locoregional relapse free, distant metastasis free, failure free, and overall survival rates were 97.0%, 86.4%, 82.0%, and 88.1%, respectively. The 4-year cumulative incidence rate of late toxicities with grade 3 or more was 3.0%. One year after CCRT, most QOL scales, except some oral related symptoms, recovered to baseline level. Conclusion: CCRT with SIB-VMAT produces excellent locoregional control, few severe late toxicity, and good general health status for NPC patients.
