Central (Medullary) Fibrosarcoma of Bone

Abstract

1. Central or medullary fibrosarcoma is an entity and must be considered separately from similar tumors arising in the periosteum or parosteally as well as from true osteogenic (bone-forming) sarcomata. 2. The five-year survival rate in these tumor cases is much worse than in those of soft-tissue sarcomata of similar nature, but appreciably better than in those of true osteogenic sarcoma. 3. From our series it would seem that once a patient has survived for two years, the chance of a permanent cure is good.
