放射治疗是晚期非小细胞肺癌 (NSCLC)患者主要的治疗方法。放疗的基本目的就是努力提高放射治疗的增益比 ,即最大限度地提高肿瘤的照射剂量而减少周围正常组织的照射剂量。适形放射治疗是一种提高治疗增益比的有效措施。我们利用三维放射治疗计划系统比较常规放射治疗与适形放
Radiation therapy is the primary treatment for patients with advanced non-small cell lung cancer (NSCLC). The basic purpose of radiotherapy is to work hard to improve the gain ratio of radiotherapy, that is, to maximize the tumor radiation dose and reduce the radiation dose of the surrounding normal tissue. Conformal radiotherapy is an effective measure to increase the treatment gain ratio. We use a three-dimensional radiotherapy planning system to compare conventional radiotherapy and conformal release
