目的 :研究骨转移瘤放疗止痛的疗效。方法 :6 5例骨转移瘤的患者在化疗间歇期于最感疼痛的部位予40 0cGy/次× 5次 /周 =2 0Gy姑息止痛放疗 ,于放疗后持续观察放疗止痛的效果。结果 :6 5例骨转移瘤患者经姑息放疗后止痛有效率 (CR +PR)于放疗后 1周时为 40 .0 % ,2周时 84.6 % ,4周时为 90 .7%。毒副作用无明显增加。结论 :化疗间歇期予上述姑息止痛放疗是一种安全有效的止痛方法。
Objective:To study the effect that the pain of bone metastatic carcinoma were treated by irradiation in the interval between two cycles chemotherapy.Methods:Sixty-five patients with bone metastatic carcinoma were treated by irradiation in the interval between two cycles of chemotherapy,the dose of radiotherapy was 400 cGy/faction,five factions every week D-T=20 Gy.Then researched the rate of relieved pain.Results:The experiment shows that the rate of relieved pain (CR+PR) was 40.0% after one week,84.6% after two weeks,90.7% after four weeks,the side-effect doesn't increase.Conclusion:The irradiation between two cycles chemotherapy was effective and safe.
