Biomarker in Tissue Samples From Patients With Ewing Sarcoma

July 7, 2016 updated by: Children's Oncology Group

INI-1 Deletions in Ewing Sarcoma

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.
