头颈部腺样囊性癌放射治疗的研究进展

头颈部腺样囊性癌发病率较低，目前主要治疗手段为手术联合术后放射治疗，但对于术后放射治疗的必要性及选取何种放射治疗手段可以使患者获益最大的问题目前仍有广泛争议。本文综合各方面因素，考虑目前头颈部腺样囊性癌的术后放疗主要以常规光子放疗为主，中子放疗虽能提高局部控制率，但晚期毒性反应不可忽视，质子、碳离子放疗虽有其物理特点上的优势，但因病例数少，且其放疗机器价格昂贵等客观障碍，尚未收集足够数据证明其优势。

Progress in Radiotherapy for Adenoid Cystic Carcinoma of the Head and Neck

The incidence of adenoid cystic carcinoma of the head and neckis low. The main treatment is surgery combined with postoperative radiotherapy. However, the necessary of postoperative radiotherapy and the which kind of radiotherapy can maximize the patient's benefit is still conversional. This article compares the advantages and disadvantages of the main radiotherapy methods for ACCHN. The conclusion is that photon radiotherapy is the main method. Although neutron radiotherapy can improve the local control rate, the late toxicity can't be ignored. Proton and carbon-ion radiotherapy have the advantages of their physical characteristics, but the number of cases is small, and the radiotherapy machine is expensive. There's not enough data could been collected to prove its advantages.
