Changing indications for bone scintigraphy in patients with osteosarcoma.
Fifty-six patients with osteosarcoma were studied to determine the onset of pulmonary and bone metastases. While pulmonary metastases were always detected prior to bone metastases in the era before adjuvant chemotherapy, in this study of patients on adjuvant therapy 16% of patients with metastases showed osseous metastases prior to or without pulmonary metastases.
