The record of 73 patients with 153 sites of bone metastases from a lung cancer treated by radiation have been reviewed to evaluate the effectiveness of pain relief. Radiation therapy for bone metastases was found to be very effective. Sufficient symptomatic improvement was achieved in 94% of all patients, while 63% obtained almost complete pain relief that was sustained until death. Onset of a symptomatic response to radiotherapy was within less than 20 Gy in total dose in more than 80% of all patients. There were no significant differences in the frequency of pain relief among the various histological types of primary lung tumors.
回顾了73例肺癌骨转移患者153处骨转移灶接受放疗的记录，以评估疼痛缓解的效果。发现骨转移的放射治疗非常有效。94%的患者症状得到充分改善，63%的患者几乎完全缓解疼痛直至死亡。超过80%的患者对放疗出现症状缓解的总剂量在20Gy以内。不同组织学类型的原发性肺癌在疼痛缓解频率上无显著差异。
