The purpose of this study is to compare the toxicity and therapeutic efficacy of photon or proton combined with carbon ion radiotherapy for newly diagnosed nasopharyngeal carcinoma.Participants will be randomized to 2 arms. Arm 1 participants received photon combined with carbon ion radiotherapy (photon: 56 Gy/28 Fx, plus carbon: 15-17.5 gray equivalent [GyE]/5 Fx for boost). Arm 2, participants received proton combined with carbon ion radiotherapy (proton: 56 GyE/28 Fx, plus carbon: 15-17.5 GyE/5 Fx for boost). Adverse events will be documented according to CTCAE v4.03.The response of treatment will be evaluated according to RECIST criteria.
