Metastatic osteosarcoma and multiple lung resection. A case report.

The existence of pulmonary metastases in patients presenting with osteosarcoma is known to indicate a poor prognosis. Lung resection of solitary lesions is now a standard treatment approach, but with limited successful long-term results. We report the progress of a 16-year-old girl with osteosarcoma of the proximal tibia who underwent 11 lung resections for pulmonary metastases over a two-year period, and who has since then been free of disease for seven years.
