RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors identify biomarkers related to cancer.

PURPOSE: This clinical trial studies tumor tissue from patients with rhabdomyosarcoma to identify important proteins and biomarkers.

Condition Intervention
Genetic: microarray analysis
Genetic: protein expression analysis
Other: immunohistochemistry staining method
Other: laboratory biomarker analysis

Study Type: Observational
Official Title: Developmental Pathway Drug-Targets in Advanced Rhabdomyosarcomas

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Prevalence of the candidate target (Pax3, Pax7, or Patched-1), and whether the candidate target is expressed in the tumor vs stroma [ Designated as safety issue: No ]

Estimated Enrollment: 24
Study Start Date: August 2012
Estimated Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Detailed Description:


  • To investigate whether the expression of a subset of proteins (by immunohistochemistry), known to be involved in the Pax3, Pax7, and Patched-1 neuromuscular development pathways, are dysregulated in advanced and relapsed alveolar and embryonal rhabdomyosarcomas.

OUTLINE: Iimmunohistochemistry is performed for each candidate target (Pax3, Pax7, and Patched-1) in each disease (alveolar, embryonal, and anaplastic rhabdomyosarcoma) for tissue microarray analysis.
