为了提高食管癌放射治疗的远期疗效 ,减少心肺、脊髓的受量 ,放疗前模拟机定位是十分重要的 ,但由于某些因素致使靶区位置发生不同程度改变 ,为求准确的照射位置 ,放疗过程中模拟机定位复查的重要性是不可忽视的。我们总结资料完整的 2 2 8例食管癌放射治疗病人 ,现将结果报告?
In order to improve the long-term efficacy of radiotherapy for esophageal cancer and reduce the amount of cardiopulmonary and spinal cord, the location of simulator before radiotherapy is very important. However, due to some factors, the target area changes in varying degrees. In order to obtain accurate irradiation position, The importance of simulator positioning review during radiotherapy can not be ignored. We summarize the complete data of 228 cases of esophageal cancer radiotherapy patients, the results reported?
