Studying Biomarkers in Samples From Young Patients With Rhabdoid Tumors
RATIONALE: Studying samples of tissue from patients with rhabdoid tumors in the laboratory may help doctor learn more about changes that occur in DNA and identify genes related to cancer.

|Study Design:||Observational Model: Case-Only
Time Perspective: Retrospective
|Official Title:||Endogenous DNA Transposition in Rhabdoid Tumors|
- Expression and function of transposons in rhabdoid tumors
|Study Start Date:||March 2012|
|Primary Completion Date:||May 2016 (Final data collection date for primary outcome measure)|
- To investigate the expression and function of transposons in 50 primary rhabdoid tumors.
OUTLINE: Freshly frozen rhabdoid tumors will be studied using fluorescence in situ hybridization (FISH) and polymerase chain reaction (PCR) to establish the genomic location of transposons. Protein expression in rhabdoid tumor tissue microarrays is also analyzed.
