Last Update Posted : May 19, 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 tumor tissue samples from patients with rhabdomyosarcoma.
|Condition or disease||Intervention/treatment|
|Sarcoma||Genetic: gene expression analysis Other: immunohistochemistry staining method Other: laboratory biomarker analysis Other: mass spectrometry|
- To determine and quantify the degree of surface insulin-like growth factor I receptor (IGF-IR) expression in rhabdomyosarcoma (RMS) tumor tissue.
- To assess the feasibility and validity of a mass spectrometry assay for IGF-IR expression on paraffin-embedded tumor tissue.
OUTLINE: Paraffin-embedded tumor tissue slides are analyzed for insulin-like growth factor I receptor (IGF-1R) expression by mass spectrometry and correlated with the results obtained by IHC assay.
