A COG Study for Collecting and Banking Ewing Sarcoma Specimens
Trial status: Open for Enrollment
Why is this study being done?
I. Collect biological specimens, including associated demographic and clinical data, from patients with Ewing sarcoma.
II. Provide a repository for long-term storage of Ewing sarcoma-related biological materials.
III. Make collected specimens available to qualified researchers to understand the biology of Ewing sarcoma and correlate these results with demographic and clinical data.
OUTLINE: This is a multicenter study.
Patients undergo collection of tumor specimens, bone marrow, and peripheral blood at diagnosis. Associated demographic and clinical data are collected and archived. Patients who are not enrolled on a therapeutic clinical trial are followed annually.
Who is eligible to participate?
- Diagnosis of Ewing sarcoma, including peripheral primitive neuroectodermal tumor and Askin tumor
- Newly diagnosed or recurrent disease
