摘　　要：目的观察放射治疗对骨转移癌疼痛的缓解效果。方法59例患者83处骨转移灶均采用^60Co放射治疗。采用2种方案：DT28～50Gy，14～25次；DT25～40 Gy，6～10次。结果分次方案对疼痛缓解率无明显影响，总有效率为94．9％，但常规分次放疗3～4次后疼痛缓解，而低分割放疗1～2次后疼痛缓解。结论骨转移癌放射治疗止痛效果确切、迅速，副作用小，对大部份病例可采用低分割方案。Objective To observe the treatment result of radiotherapy for pain of bone metastases. Methods 59 patients with 83 painful metastases were treated with ^60Co irradiation. Two treatment regimens were used ：28 -50 Gy in 14-25 fractions and 25-40 Gy in 6-10 fractions. Results The total effective rate was 94.9%. There was no significant different in pain relief rate between the different fractionation regimens. After 3- 4 fractions of routine fmctionation regimen, the pain relief occurred, while the hypofractionation regimen could relief pain after only 1-2 fractions. Conclusion Radiotherapy for reliefing pain of bone metastases is clearly effective, quick with minor side effects. The hypofractionation regimen is suitable for most patients with bone metastasis.
