Osteosarcoma

osteosarcoma

osteosarcoma (osteogenic sarcoma) (osti-oh-sar-koh-mă) n. a highly malignant tumour arising from within a bone. In children the usual site for the tumour is the leg, particularly the femur. Secondary growths (metastases) are common, most frequently in the lungs (though other sites, such as the liver, may also be involved). Treatment of disease localized to the primary site is now usually by limb-sparing surgery after neoadjuvant chemotherapy, with replacement of the diseased bone by a metal prosthesis.
