摘　　要：为了观察骨转移肿瘤不同分割方式对放射止痛的治疗效果,90例患者中44例采用常规分割照射,2Gy/次,每周5次,DT36~50Gy;46例采用大分割照射,(3~5)Gy/次,每周3~5次,DT20~30Gy。结果全组病例止痛有效率(CR+PR)为91.11%;常规分割组CR+PR为90.90%,大分割组CR+PR为91.30%,两组比较差异无统计学意义,P=0.95。常规分割组单发转移灶CR+PR为91.67%,多发转移灶CR+PR为90.00%,放疗止痛疗效相近,P=0.85;大分割组单发转移灶CR+PR为93.75%,多发转移灶CR+PR为90.00%,放疗止痛疗效相近,P=0.67。初步研究结果提示,骨转移肿瘤进行局部止痛放疗是一种非常有效的治疗手段,两种分割方式之间无明显疗效差异。The objective of this study was to investigate the efficacy of radiation with various fractionation schemes for pain relief in patients with bone metastasis. Ninety cases of bone metastasis were divided into two groups, the conventional radiotherapy was performed in 44 cases in the way of 36-50 Gy, 5 fractions/week, 2 Gy/fraction; the big fractionated radiotherapy was performed in 46 cases in the way of 20-30 Gy, 3-5 fractions/week, 3-5 Gy/fraction, and the two fractionation schemes were practiced for the p...
