Last Update Posted : July 11, 2016
RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.
PURPOSE: This research trial studies biomarkers in tissue samples from patients with Ewing sarcoma.
|Condition or disease||Intervention/treatment|
|Sarcoma||Genetic: microarray analysis Genetic: protein analysis Other: immunohistochemistry staining method Other: laboratory biomarker analysis|
- To determine the frequency of INI-1 protein loss in Ewing Sarcoma.
OUTLINE: Previously collected tissue samples are analyzed for INI-1 protein loss by IHC and tissue microarray.
