甲状腺相关眼病的放射治疗进展

甲状腺相关眼病是一种机制不清的自身免疫疾病,放射治疗对缓解眼部症状有一定疗效,对传统放疗技术的沿用可能是有效率无明显提高的主要原因.随着放射治疗技术的发展,靶区、剂量等更多问题值得探讨,尤其是调强放疗,相比传统放疗,它具有靶区内剂量分布均匀、靶区外剂量梯度大等特点,可能对提高有效率、保护正常组织更有帮助.

The development of radiotherapy for thyroid associated ophthalmopathy

Thyroid-associated ophthalmopathy is an autoimmune disease with unclear mechanism.Radiotherapy has certain curative effect to relieve the eye symptoms.Usage of traditional radiotherapy technology might be the reason of no discernible improved efficiency.However,with the progress of radiotherapy,it is found that more problems like target volume,dose and radiotherapy which is especially stressed deserves further investigation.Compared with the traditional radiotherapy,the modem radiotherapy is featured with even dose distribution in target volume and large dose gradient outside target volume.Therefore,it is more helpful in improving efficiency and protecting normal tissue.
