【摘要】 目的　探讨放射治疗不同分割方式对恶性肿瘤骨转移的止痛效果。方法　回顾分析我科1996年 1月～ 2 0 0 0年 5月间采用大剂量低分割方式及常规分割方式放射治疗骨转移癌止痛疗效。结果　 4 3例 5 6处骨转移灶放疗后止痛总有效率为 94 .6 % (5 3 5 6 ) ,大剂量低分割组有效率为 93.5 % (2 9 31) ,常规分割剂量组有效率为 96 .0 % (2 4 2 5 ) ,两组止痛有效率对比无差异。结论　放射治疗骨转移骨痛 ,是一种好的止痛方法 ,止痛疗效与分割方式无关。更多还原

【Abstract】 Objective To study the effects of radiotherapy in 43 patients with skeletal metastases from cancer.Methods A retrospective study was conducted in 43 patients with skeletal metastases from cancer treated by lower fractionation radiotherapy(LFR) or convention fractionation radiotherapy(CFR) during the period between January 1996 to May 2000.Results A total effective rate of 94.6%(53/56)was achieved after radiotherapy.The effective rates of LFR and CFR were 93.5%(29/31)and 96.0%(24/25).The differences between these two groups were no significant.Conclusion The results suggest radiotherapy is a good pain reliever in patients with metastatic cancer of the bone.LFR could be as good as CRF. 〔更多还原
