放疗正广泛应用于骨转移疼痛的控制和预防其骨折。局部放疗可使73％～96％的病人部分或完全缓解。一些回顾性研究已证明,短期分割放疗(1～5次内给予5～20Gy)与较长期的分割放疗(2.5～4.5周内给予30～45Gy)其效果相同。因其中位生存期很短,故在大多数研究中很难评估对生存期的影响。然而单次分割与多次分割方案各自优越性已有报道。作者对52例来自不同部位和单发或多发骨转移病人进行姑息性放疗。根据病历记载可作回顾性评估的有34例,包括82个转移部位。其原发灶部位及例数各为:乳腺(4),前列腺(4),骨髓瘤(4),胰腺(4),子宫颈(3),肾(3),其他部位(12)。其中 Radiotherapy is widely used to control bone pain and prevent fractures. Local radiotherapy can partially or completely relieve 73% to 96% of patients. Some retrospective studies have shown that short-term split radiotherapy (5 to 20 Gy within 1 to 5 sessions) and longer-term split radiotherapy (30 to 45 Gy within 2.5 to 4.5 weeks) have the same effect. Because of its short median survival, it is difficult to assess the impact on survival in most studies. However, the superiority of single and multiple segmentation schemes has been reported. The authors performed palliative radiotherapy on 52 patients from different sites and single or multiple bone metastases. According to medical records, 34 cases can be retrospectively evaluated, including 82 metastatic sites. The primary site and the number of cases were: breast (4), prostate (4), myeloma (4), pancreas (4), cervix (3), kidney (3), and other sites (12). among them
