[Usefulness of stratigraphy and computerized tomography in the initial staging of osteosarcoma of the extremities. Retrospective study of 217 cases].
The value of stratigraphy and pulmonary CT in the initial work-up of osteosarcoma of the extremities is assessed with reference to 217 patients encountered in the Bone Tumour Centre of Rizzoli Orthopaedic Institute in May 1983-May 1986. Stratigraphy revealed lung metastases not identified by standard radiography in 4 patients (1.8%), while CT revealed metastases not identified by either standard X-rays or stratigraphy in a further 6 cases (2.7%). It is concluded that the increase in the percentage of cures (about 30%) reported in the last 10 years in osteosarcoma cases given adjuvant chemotherapy cannot be explained by any difference in initial selection due to the use of these techniques that were not adopted in the historical series.
