Brief Summary:
This research trial studies protein expression in tissue 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.

Detailed Description:

PRIMARY OBJECTIVES:

I. To investigate (in two stages) which proteins are overexpressed in association with 12q13-q14 amplification by applying fluorescence in situ hybridization (FISH) and immunohistochemical (IHC) assays to a panel of alveolar rhabdomyosarcomas (ARMS) cases organized into tissue microarrays.

OUTLINE:

Formalin-fixed paraffin-embedded tissue samples are analyzed for 12q13-q14 frequency and protein overexpression by FISH and IHC.


Study Type : Observational
Actual Enrollment : 99 participants
Observational Model: Cohort
Time Perspective: Retrospective
Official Title: Tissue Microarray Studies of the 12q13-q14 Amplicon in Alveolar Rhabdomyosarcoma
Study Start Date : June 2012

Other: laboratory biomarker analysis
Correlative studies



Primary Outcome Measures :
  1. Amplification and fusion status as a result of the 12q13-q14 amplification event [ Time Frame: Baseline ]
    Fisher's exact test will be used. For a contingency table other than 2 x 2, the Freeman-Halton test (an extension of Fisher's exact test) will be applied instead.
