골반골의 악성종양

Abstract

Malignant tumor of the pelvic bone has nonspecific symptom and it is not easily detected by physical examination or by radiologic study in early stage, because of its anatomical characteristics. Associated with their variety of disease entity, the treatment of malignant pelvic bone tumor is a problematic point. We have analysed 35 cases of malignant pelvic bone tumors diagnosed at the Severance hospital from 1968 to 1993 to provide a reference for diagnosis and treatment of the malignant pelvic bone tumors. We found that the chondrosarcoma(27.8%) and the osteogenic sarcoma(27.8%) were the most common type of pelvic bone malignancy, and then, in the order of incidence, there were Ewing’s sarcoma(16.7%), malignant fibrous histiocytoma(11.1%). There were differences of the age distribution among each diseases and the average age was Ewing’s sarcoma 20.5, osteogenic sarcoma 27.2, chondrosarcoma 40.0, malignant fibrous histiocytoma 64.8, respectively. Three of the 5 patients with low grade tumors survived(60%), whereas 3 of the 17 patients with high grade tumors survived(18%). The survival rate of the low grade malignant group was 60%, the high grade was 18%.
