To compare 3 local field radiation therapies for bone metastases to determine the strategy producing the best results. Methods: Among 104 patients with bone metastases, 30 patients were given 8 Gy in single fraction, 31 given 20 Gy in 5 fractions, 43 given 40Gy in 20 fractions. Results and Conclusion: The method of 40 Gy in 20 fractions had a higher pain relief rate and a lower pain relapse rate, suggesting that large-dose fractioned treatment regimen is more appropriate for patients with bone metastasis.
