Brief Summary
This laboratory study is looking into mechanisms of radiation therapy resistance in samples from younger patients with rhabdomyosarcoma. 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. It may also help doctors find better ways to treat cancer

Novel pathway/biomarkers detected within clinically annotated patient tumor tissue samples
Up to 1 year
Study Arms (1)
Correlative (laboratory biomarker analysis)
Archived tissue samples of matched primary-relapsed and non-matched primary are analyzed for genomic DNA, DNA methylation profiles, RNA sequencing, differences between alveolar rhabdomyosarcoma (ARMS) and embryonal rhabdomyosarcoma (ERMS), gene expression profiles, target-of-rapamycin complex 1 (TORC1) and TORC2 pathway intermediates, and paired box 3 (PAX3)/forkhead box O1 (FOXO1) translocation by microarray, immunohistochemical staining, and fluorescence in situ hybridization (FISH).

Eligibility Criteria
Patients with rhabdomyosarcoma enrolled on COG-D9902.
You may qualify if:
- Tissues requested from the Children Oncology Group (COG) sarcoma banking protocol COG-D9902
- All subtypes of rhabdomyosarcoma specimens
- Matched primary-relapsed specimens (from same patient, separated by time):
- Frozen tissue if available
- Scrolls of formalin-fixed paraffin-embedded tissue (if frozen not available)
- unstained formalin-fixed paraffin-embedded thin sections
- All other general (primary or relapsed) cases
- unstained formalin-fixed paraffin-embedded thin sections
