Outcome for children with metastatic solid tumors over the last four decades

Outcomes for pediatric solid tumors have significantly improved over the last 30 years. However, much of this improvement is due to improved outcome for patients with localized disease. Here we evaluate overall survival (OS) for pediatric patients with metastatic disease over the last 40 years. The United States Surveillance, Epidemiology, and End Results (SEER) database was used to conduct this study. Patients diagnosed between 0 and 18 years of age with metastatic Ewings sarcoma, neuroblastoma, osteosarcoma, rhabdomyosarcoma or Wilms tumor were included in the analysis. 3,009 patients diagnosed between 1973-2010 met inclusion criteria for analysis. OS at 10 years for patients diagnosed between 1973-1979, 1980-1989, 1990-1999 and 2000-2010 was 28.3%, 37.2%, 44.7% and 49.3%, respectively (p
