Osteosarcoma/Malignant Fibrous Histiocytoma of Bone (PDQ®): Treatment
This cancer treatment information summary provides an overview of the prognosis, diagnosis, classification, and treatment of osteosarcoma and malignant fibrous histiocytoma of bone.

Osteosarcoma is the most common primary malignant tumor of bone, excluding plasma cell myeloma. Approximately 75% of all osteosarcomas are of the classic or conventional type, and the remaining 25% comprise the osteosarcoma variants, which are the subject of this article. The variants are a heterogeneous group of osteosarcomas with...

The osteosarcoma is the commonest of the primary malignant bone tumours. Its peak incidence is before epiphyseal fusion, particularly the years between 10 -25. There is a later peak which is associated with Paget's disease or previous radiotherapy. Visible Paget's disease does not have to be present before one can...

Wide resection and mobile joint reconstruction are preferable for treating an osteosarcoma around the knee. In certain situations, resection arthrodesis or an amputation is suggested. This study compares the outcome in these three groups (not randomized so liable to selection bias (OWL editor))
CONCLUSIONS: The importance of early and proper planning...

Osteosarcoma is the most common primary malignant bone tumor in children and adolescents. When first recognized, telangiectatic osteosarcoma was proposed to be a distinct clinical and pathologic entity.1 On the basis of subsequent findings that provided a better understanding of the condition's presentation and prognostic implications, telangiectatic osteosarcoma should be...

A retrospective study of patients with osteosarcoma was undertaken to determine whether there was a relationship between biopsy and survival. Twenty-four of the fifty-seven patients had an amputation without a prior biopsy; the others had biopsies before amputation. These two groups were fairly closely matched in age, sex, site and...
