目的 :探讨不同分割剂量放疗对骨转移瘤的镇痛疗效。方法 :对 10 0例骨转移瘤患者2 38个病灶采用不同分割剂量放疗 ,2 Gy组 10 4个 ,3Gy组 98个 ,5 Gy组 36个。结果 :2 Gy组 :CR率76 .9% ,PR率 13.4 % ,总有效率 90 .4 % ,3Gy组 :CR率 71.4 % ,PR率 17.4 % ,总有效率 88.8% ,5 Gy组 :CR率 6 9.4 % ,PR率 16 .7% ,总有效率 86 .1% ,χ2 =0 .714 ,P>0 .0 5 ,组间无显著性差异。结论 :不同分割剂量放疗对骨转移瘤镇痛疗效无明显差异 ,2 Gy组 CR率可能提高。
Objective: To investigate the analgesic effects of different doses of radiation on bone metastases. Methods: Two hundred and seventy lesions of 100 patients with bone metastases were treated with different doses of divided radiotherapy, 104 in 2 Gy group, 98 in 3Gy group and 36 in 5 Gy group. Results: The 2 Gy group had a CR rate of 76.9%, a PR rate of 13.4% and a total effective rate of 90.4%. In the 3Gy group, the CR rate was 71.4%, the PR rate was 17.4% and the total effective rate was 88.8% The rate of 6 9.4%, PR rate of 16.7%, the total effective rate of 86.1%, χ2 = 0. 714, P> 0.05, no significant difference between the groups. Conclusion: There is no significant difference between the two groups in the dose-fractionated radiotherapy and analgesia for bone metastases. CR rate in 2 Gy group may be increased.
