目的观察放射治疗脊椎(胸椎、腰椎)转移癌的疗效。方法经X线、CT、ECT、MRI检查确诊的脊椎(胸椎、腰椎)转移癌患者,其中轻度疼痛2例,中度疼痛32例,重度疼痛16例。采用6mv-X射线常规外照射治疗。射野范围包括转移椎体及上下各1/2椎体,病灶边缘旁开2.0cm,每次2.0Gy,每周5f,照射36-40Gy时成角避脊髓照射,至总量50-55Gy结束。重度疼痛采用大剂量冲击放射治疗,达到快速止痛的效果。疗程短,每次3.0Gy,照射10f,总量30Gy。结果疼痛症状完全缓解CR68%,部分缓解PR28%,总有效率96%。结论常规放射治疗多椎体骨转移癌的目的是提高病灶的放射剂量,降低局部复发率,减少病理性骨折发生。缩小病灶的同时获得较好的止痛效果,提高生存质量,延长生存期。
Objective To observe the curative effect of radiotherapy on the metastasis of the spine (thoracic, lumbar). Methods The patients with spine (thoracic, lumbar) metastatic carcinoma diagnosed by X-ray, CT, ECT and MRI were examined. There were 2 mild pain, 32 moderate pain and 16 severe pain. Using 6mv-X-ray conventional external irradiation treatment. Radiography range includes the transfer of vertebral body and the upper and lower 1/2 vertebral body, the edge of the lesions next to open 2.0cm, each 2.0Gy, 5f per week, radiation 36-40Gy angle into the spinal cord to avoid radiation until the end of the total amount of 50-55Gy . Severe pain using high-dose impact radiation therapy, to achieve rapid analgesic effect. Short course, each 3.0Gy, irradiation 10f, the total 30Gy. Results Pain relief CR68%, partial relief PR28%, the total efficiency of 96%. Conclusion The purpose of conventional radiotherapy for the treatment of multi-vertebral body bone metastases is to increase the radiation dose of the lesion, reduce the local recurrence rate and reduce the incidence of pathological fractures. Narrow the lesion at the same time get a better analgesic effect, improve quality of life and prolong survival.
