Background
- Highly aggressive malignant bone or soft tissue tumor arising from cells of the neuroectoderm
- One-fourth of patients will have metastasis at the time of presentation
- It is assumed that almost all patients have subclinical metastasis
- Presence and location of metastasis is the major prognostic factor for survival
- Metastasis is most frequently seen in bone (spine most common) and lungs
- Around 70 to 80 percent survival in those with non-metastatic disease
- More common in males
