The authors report on the analgesic effect of 44 patients and 61 sites of malignant tumor bone metastases treated with linear accelerator radiotherapy. 1. Clinical data 44 cases of 27 males and 17 females, aged 32 to 86 years, primary tumor lung cancer 41%, breast cancer 29.8%. All bone metastases were confirmed by conventional X-ray, bone scan or CT examination. 59.6% of the site is displaced by the spine and pelvis, and the rest are ribs, femurs, sacrum and sternum. There were 28 cases of solitary bone metastases and 16 cases of multiple bone metastases. Three patients had metastases with other organs outside the bone, and all patients showed pain. Forty patients had used drugs to relieve pain in varying degrees and were not relieved. Thirty-one patients were treated with primary lesions before the treatment of bone metastases, and 13 primary lesions were uncontrolled or untreated.
