骨转移癌常作为一些恶性肿瘤如乳腺癌、前列腺癌和肺癌等扩散的首要证据而出现,即使预后很差,也应积极地对症治疗。其目的是缓解疼痛、防止病理性骨折发生、改善活动度和功能,并尽可能延长生存期。局部放疗是骨转移癌疼痛的非常有效的治疗方法。为了比较单次和分次放疗的疗效,作者对Aarhus等多中心1989～1994年间241例骨转移癌病人的随机性资料作了回顾性分析。该组病人的原发灶为乳腺癌(39％)、前列腺癌(34％)、肺癌
Bone metastases often appear as the first evidence of the spread of malignant tumors such as breast cancer, prostate cancer, and lung cancer. Even if the prognosis is poor, symptomatic treatment should be actively treated. Its purpose is to relieve pain, prevent pathological fractures, improve mobility and function, and maximize survival. Local radiotherapy is a very effective treatment for bone metastatic cancer pain. In order to compare the efficacy of single and fractional radiotherapy, the authors retrospectively analyzed the randomized data of 241 patients with bone metastases from Aarhus et al. from 1989 to 1994. The primary lesions in this group were breast cancer (39%), prostate cancer (34%), and lung cancer.
