Abstract
The material consisted of 229 cases which were found radiologically to have bone metastasis from May of 1962 for 3 years at the National Cancer Center Hospital This report is the study of the radiological changes of the metastatic bone lesion by the various treatments.
1. Bone metastasis primarily occurred to the particular site of the scapula, humerus, femur and of the hip bone.
2. The pictures of the improvement in the metastatic lesion were generally the reappearance of the bone contour and its clear manifestation in the bone cortex, the sclerosis around the osteolytic area and the patchy sclerosis in the spongiosa.
3. The radiological remission rate was 22.2 oa in the osteolytic type, 46.8% in the combined type and 44.4% in the osteoplastic type of bone metastasis. It was higher rate in the cases of the combined type and of the osteoplastic type.
