The early detection of metastatic spread in sixteen patients with osteosarcoma has been studied over a twelve month period, comparing the techniques of bone scanning and radiography. In only two patients were we able to demonstrate changes suggestive of pulmonary metastases any earlier with a 99mTc-EHDP scan than with chest radiographs and one of these resolved spontaneously. However, the bone scan did accurately delineate the extent of the primary tumour and may, therefore, be helpful in deciding the level of the amputation and the response of the patient to treatment, particularly now that chemotherapy and immunotherapy are frequently used in the management of the disease.
