摘　　要：目的 通过对比分析局部野放射治疗骨转移瘤的3种分割方法，以寻求产生最好效果的方法。材料和方法 104例骨转移患者，其中30例单次放疗8 Gy，31例4 Gy×5次，43例2 Gy×20次。结果与结论 2 Gy×20次的放疗方法产生较高的疼痛缓解率，较低的疼痛复发率，说明较高剂量的、分割照射疗效较佳。Objective By comparing 3 methods of local field radiation therapy for bone metastases to determine the techniques producing the best results. Materials and methods Among 104 patients with bone metastases, 30 patients were given a single dose of 8 Gy, 31 patients received a total dose of 20 Gy in 5 fractions, and 43 patients with a total dose of 40 Gy in 20 fractions. Results and Conclusions The total dosage of 40 Gy in 20 fractions can produce a higher pain relief rate and a lower pain relapse rate, suggesting that the higher dose fractioned treatment regimen may ensure better result in pain relief for patients with bone metastasis.
