The purpose of this study is to determine the efficacy and safety of particle therapy with or without apatinib as induction therapy for the treatment of head and neck adenoid cystic carcinoma. It is a randomized phase II clinical trial with single phase and 2 experimental arms. Participants will be randomized to arm 1, receiving apatinib (0.5g, daily) for 6 weekly followed by particle radiotherapy (proton: 56 GyE/28 Fx, plus carbon: 15 GyE/5 Fx for boost); arm 2: particle radiotherapy alone (proton: 56 GyE/28 Fx, plus carbon: 15 GyE/5 Fx for boost). The short term response will be evaluated using RECIST criteria. And the acute and late toxicities will be evaluated according to NCI CTCAE v4.03.
