56例恶性肿瘤患者分为两组,对照组26例运用常规放疗方法,试验组30例则运用椎体转移三维适形放疗技术治疗。对照组应用传统的常规治疗方法,主要是30～36Gy/10～12次、5次/周的分隔式放疗,试验组应用椎体转移三维适形放疗技术,主要是42～45Gy/14～15次、5次/周的分隔式放疗。结果椎体转移三维适形放疗的方法和传统的常规放疗无明显差异,但椎体三维适形放疗技术可改善靶区的剂量分布,起到保护骨髓的作用。
56 cases of malignant tumor patients were divided into two groups, control group, 26 cases using conventional radiotherapy methods, the experimental group of 30 cases were treated with three-dimensional conformal radiotherapy vertebral body transfer therapy. The control group was treated by conventional conventional therapy, mainly 30 ~ 36Gy / 10 ~ 12 times, 5 times / week radiotherapy. The experimental group was treated with three-dimensional conformal radiotherapy of vertebral body metastasis, mainly 42 ~ 45Gy / 14 ~ 15 Times, 5 times / week of split radiotherapy. Results The method of three-dimensional conformal radiotherapy of vertebral metastasis had no significant difference with conventional radiotherapy. However, the three-dimensional conformal radiotherapy of vertebral body could improve the dose distribution of the target area and protect the bone marrow.
