Induction Chemotherapy, Nasopharyngeal Carcinoma, Radiotherapy

Brief summary

To evaluate the long-term locoregional control, survival rate, late toxicity and quality of life after reducing the target volume in patients with locoregionally advanced nasopharyngeal carcinoma patients treated with induction chemotherapy plus concurrent chemoradiotherapy.

Detailed description

This phase 3, multicenter, non-inferiority, randomized controlled clinical trial recruits patients with newly-diagnosed locoregionally advanced nasopharyngeal carcinoma patients treated with induction chemotherapy plus concurrent chemoradiotherapy. The intervention is delineating the gross tumor volume according to pretreatment tumor extension (the pre-IC GTV group) or post-induction chemotherapy tumor extension (the post-IC GTV group). The objective is to compare the long-term locoregional control, survival rate, late toxicity and quality of life between the two groups.
