title: [Prognosis for the cases after resection of pulmonary metastasis of osteosarcoma].
abstract: Osteosarcoma commonly metastasize to the lungs. Sixty-six cases with surgical treatment for pulmonary metastasis of osteosarcomas have been experienced for past 25 years in our hospital. Disease free interval (DFI) and the number of metastatic lesions were assessed in relation to their prognosis. As a result of our assessment, fewer metastasis (3 or less), and longer DFI (1 year or more) had relations to longer post-thoracotomy survival. And the relations between the number of metastatic lesions and DFI were found. Fewer metastasis were associated with longer DFI, and multiple metastasis were associated with short DFI. The cases with fewer metastasis (3 or less) and longer DFI (1 year or more) might have a survival advantage.
