[摘要] 放疗是治疗胸部恶性肿瘤的主要手段之一,然其不可避免地会累及正常组织,肺是电离辐射中度敏感器官,因此极易造成放射性肺损伤,其主要表现为两个阶段,即早期的放射性肺炎期和后期不可逆转的放射性肺纤维化期,严重降低患者的生活质量,甚至发生呼吸衰竭而危及患者生命。放射性肺损伤还极大地限制了放射剂量,影响疗效,甚至使放疗被迫中断。本文就放射性肺损伤的发生机制、现代研究、预测体系、诊断、西医防治等方面作一综述。

[Abstract] Radiotherapy is one of the main methods for treating malignant tumors of the chest. However, it is unavoidable that normal tissues are involved. The lung is a moderately sensitive organ of ionizing radiation and therefore can easily cause radiation-induced lung injury. It mainly manifests itself as two phases, namely the early stage of radiation pneumonitis periad and the irreversible radiation pulmonary fibrosis period, which seriously reduces the quality of the patient′s life and even causes respiratory failure and endangers the life of the patient. Radiation-induced lung injury greatly limits the radiation dose, affects the therapeutic effect, and even forces it to be interrupted. This article reviews the mechanisms of radiation-induced lung injury, modern research, prediction systems, diagnosis, western medicine prevention and treatment.

放射治療被视作是当前综合治疗胸部肿瘤的一种有效手段。临床工作中,增加放疗剂量是提高肿瘤控制率的重要措施。然而高剂量放疗必定会带来空白组织毒性。放射性肺损伤指的是当对胸部采取放射治疗手段时,从辐射敏感度来看肺是中度敏感器官,其会由于累剂量...
