About this trial
This is a multi-center, non-inferiority, open-label, randomized controlled phase III clinical trial in primary diagnosed nasopharyngeal carcinoma (NPC) patients without distant metastasis. This study aims to compare the regional control, survival outcomes, radiation-related toxicities, and quality of life (QoL) of xerostomia-optimized intensity-modulated radiotherapy versus standard intensity-modulated radiotherapy in NPC patients
