About this trial
This is a randomized, phase III, prospective, multi-center trial in newly diagnosed nasopharyngeal carcinoma (NPC) patients without distant metastasis. The aim of this study is to evaluate the efficacy and safety of modified IMRT, of which CTV delineation was only based on geometric expansion from GTV.
