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 curative effect of radiotherapy and pain relief for bone metastases. Methods: Sixty-five patients with bone metastases were treated with palliative analgesia and radiotherapy at the site of the most pain during the intermittent chemotherapy. The effect of radiotherapy and analgesia was continuously observed after radiotherapy. Results: The effective rate of pain relief (CR + PR) after palliative radiotherapy in 65 patients with bone metastases was 40.0% at 1 week after radiotherapy, 84.6% at 2 weeks and 90.7% at 4 weeks. No significant increase in side effects. Conclusion: Intermittent chemotherapy for palliative pain and radiotherapy is a safe and effective analgesic method.
