【摘要】 随着物理学、计算机技术、影像学的发展,放射治疗方法在最近几十年也有了显著的进步与发展,而放疗技术是治疗癌症行之有效的方法。本文主要综述了胸部肿瘤的放射治疗最新的进展,其中包括乳腺癌、肺癌、食道癌和纵膈肿瘤的放射治疗。细胞对放射线的敏感性在分裂期最高,在DNA合成期其敏感性最低。放射疗法既不损伤周围正常组织,仅仅对异常增殖的癌肿给予大量的杀伤,同时机体又再次尽可能发挥最大的调节功能。伴随胸部肿瘤放疗技术的进步,对治疗这些肿瘤有非常重要的临床意义。更多还原

【Abstract】 With the development of physics,computer technology,imaging,radiation treatment in recent decades has made significant progress and development,and radiotherapy technology is a effective way in treating cancer.This article mainly summarized the latest progress of radiotherapy to thoracic tumours,including breast cancer,lung cancer,esophageal cancer and mediastinal tumor radiotherapy.Cells has the highest sensitivity to radiation in divided period,and lowest sensitivity in DNA synthesis period.Radiation therapy does not damage the surrounding normal tissues,just damage the abnormal proliferation of tumor,and also regulate function of body as possible.With the progress of the radiotherapy for thoracic tumours,there will be very important clinical significance on therapy to these tumors.更多还原
