简要总结
This is a randomized, phase III, prospective, multi-center trial in newly diagnosed nasopharyngeal carcinoma (NPC) patients without distant metastasis. This study will evaluate whether omitting Level Va irradiation in patients without these risk features does not compromise regional control or survival, with the goal of providing robust evidence to guide further personalization of NPC radiotherapy.

结局指标
主要结局
Regional failure-free survival
时间窗: 3 years
The regional relapse-free survival rate will be estimated using Kaplan-Meier method for each arm from the date of randomization to the date of nodal relapse or death from any cause, whichever occurred first. Their differences will be compared between treatment arms using the log-rank test.
次要结局
- overall survival(3 years)
- Patient's quality-of-life(3 years)
- Distant metastasis-free survival(3 years)
- Local failure-free survival(3 years)
