Currently, there is no internationally recognized staging system for Ewing sarcoma (ES).
A complete work-up for ES is outlined below:
Systemic evaluation |
|
Evaluation of extent of primary tumor site |
|
Evaluation of metastatic disease |
|
Blood work should include a baseline lactase dehydrogenase (LDH) level:
- An elevated LDH has adverse prognostic significance and suggests very bulky or metastatic disease.
Bone Marrow Aspiration Biopsy
- Essential to stage ES and exclude bone marrow metastases.
Imaging investigations
- Used to assess local and distant extent of disease. Please see radiology section.
