Brief Summary: Currently, nasopharyngeal carcinoma (NPC) patients who had level II involvement with extracapsular extension (ECE), and/or had a maximum nodal axial diameter (MAD) of greater than 2cm in level II will be recommended to receive level Ib-covering IMRT according to the International Guidelines. Our previous study, which retrospectively analyzed a cohort of 390 patients, indicated that it should be safe and feasible for patients who only had at least one of the above two radiological features. Thus, the investigators conduct this non-inferior phase 3, randomized trial to further determine the feasibility of sparing level Ib in patients who had level II involvement with ECE, and/or had a MAD of greater than 2cm in level II.
