目的探讨关于骨转移瘤常规分割放疗组与低分割放疗组的止痛效果。方法４８例病人，２８例采用常规分割，ＤＴ２００ＣＧＹ／次，每周５次，ＤＴ３０００～５０００ＣＧＹ；２０例采用低分割照射，ＤＴ４００～５００ＣＧＹ／次，每周２～３次，ＤＴ２５００～３０００ＣＧＹ。结果放疗起到了明显的止痛作用，常规分割放疗组与低分割放疗组止痛效果大致相同，无统计学意义（Ｐ＞０．０５）。结论放疗原则应根据病情及预计生存期长短来决定。对一般情况好，预计生存期长的病人应采取积极的治疗，给予大剂量长疗程的常规分割，而对于那些病情相对较重，行动又不方便，无望长期生存的病人，应采取低分割照射，且见效快，同样起到止痛作用
Objective To investigate the analgesic effect of conventional fractionated radiotherapy and low-fractionated radiotherapy for bone metastases. Methods Forty-eight patients, 28 patients were divided by routine, DT200CGY/time, 5 times per week, DT3000～5000CGY; 20 patients were treated with low segmentation, DT400～500CGY/time, 2～3 times per week, DT2500～3000CGY. Results Radiotherapy played a significant analgesic effect. The pain-relieving effects of conventional fractionated radiotherapy and low-fractionated radiotherapy groups were similar, with no statistical significance (P>0.05). Conclusion The principle of radiotherapy should be determined according to the condition and the expected length of life. For patients with good general conditions, long-lived patients are expected to take active treatment and give routine segmentation of large doses of long courses of treatment. For patients with relatively severe conditions and inconvenient actions, patients with no long-term survival should adopt low-segment irradiation. , And quick results, also play an analgesic effect
