Radiation therapy in the management of bone tumors

Radiation therapy is used in the management of both primary and metastatic bone tumors. The most common primary bone tumor in dogs and cats is osteosarcoma of the appendicular skeleton. A number of other primary bone tumors occur at a much lower rate in both species and include chondrosarcoma, fibrosarcoma, hemangiosarcoma, multiple myeloma, and lymphoma. This article reviews the results of published reports on the utility of radiation therapy in the treatment of primary and metastatic bone tumors of companion animals.
