Survival Differences in Pulmonary Metastatic Osteosarcoma Between Pediatric and Adult Institutions

Prognosis for osteosarcoma with pulmonary metastases remains poor at all ages. Pediatric surgeons often employ a more aggressive approach to surgical disease clearance compared to adult surgeons, but the survival impact is unclear. We hypothesized that patients with relapsed pulmonary metastatic osteosarcoma cared for at pediatric institutions will show improved survival compared to patients cared for at adult institutions reflecting differences in treatment approach.
