在大多数西方国家肺癌占肿瘤死亡原因第一位,其发病率仍在增长,特别是妇女的发病率的增长。在肺癌治疗上最大的问题就是在确诊时大多数病人已不适于手术切除。多年来,放射治疗在治疗肺癌上担负重要任务。放疗参数适当的剂量一些文献报告,放疗剂量超过50Gy 提高了肿瘤缓解率,区域一局部控制率,甚至生存率。Ris-san 及其同工报告一组67例尸检材料,18例在照射野内无肿瘤残存,这18例的剂量都在40Gy 以上且 In most western countries, lung cancer accounts for the first cause of cancer deaths, and its incidence is still increasing, especially for women. The biggest problem in the treatment of lung cancer is that most patients are not suitable for surgical resection at the time of diagnosis. For many years, radiation therapy has played an important role in the treatment of lung cancer. Radiotherapy parameters appropriate dose Some literature reports that radiotherapy doses of more than 50 Gy have improved tumor remission rates, regional control rates, and even survival rates. Ris-san and his colleagues reported a group of 67 autopsy materials, 18 of which had no residual tumor in the field. The doses of these 18 cases were all above 40 Gy.
