恶性肿瘤晚期常并发骨转移.根据Abrams等氏病理学统计1000例癌肿骨内发生转移的机会达27.2%.近年来由于对癌症治疗方面的进步,疗效提高,患者生存期延长,骨转移瘤发病率有渐增的趋势.治疗骨转移广泛使用放射治疗,因放疗可缓解疼痛,并可使骨转移病灶有不同程度的修复.文献中报告放射治疗对骨痛的缓解率达70～90%.包括X线片骨变化的客观有效率的报告很少.本文目的是以症状和X线表现来评价癌症骨转移放射治疗的作用.
Malignant tumors often have late bone metastases. According to Abrams et al.’s pathology, the chances of metastasis in bone in 1,000 cases of cancer are 27.2%. In recent years, due to advances in cancer treatment, the curative effect has been improved, the survival of patients has been prolonged, and bone metastases have increased. The incidence rate has an increasing trend. Radiation therapy is widely used in the treatment of bone metastases, because radiotherapy can relieve pain, and can make bone metastasis lesions have different degrees of repair. Literature reported radiotherapy for bone pain relief rate of 70 to 90% There are few reports of objective efficiency including X-ray fractures. The purpose of this article is to evaluate the role of bone metastases radiotherapy with symptoms and X-ray findings.
