DNA Tests in Detecting Disseminated Disease in Tumor, Blood, and Bone Marrow Samples From Patients With Rhabdomyosarcoma
Recruitment status was Active, not recruiting
RATIONALE: DNA analysis of tumor, blood, and bone marrow may help doctors predict if the disease has been disseminated.
PURPOSE: This research trial studies DNA tests in detecting disseminated disease in tumor, blood, and bone marrow samples from patients with rhabdomyosarcoma.
Genetic: DNA methylation analysis
Genetic: microarray analysis
Genetic: polymerase chain reaction
Other: laboratory biomarker analysis
|Official Title:||DNA Methylation-based Assays for Detecting Disease Spread in Rhabdomyosarcoma|
- Panel of hypermethylation assays for minimal disseminated RMS [ Designated as safety issue: No ]
- Detection of RMS cells in bone marrow [ Designated as safety issue: No ]
|Study Start Date:||August 2011|
|Estimated Primary Completion Date:||September 2011 (Final data collection date for primary outcome measure)|
- To establish a panel of hypermethylation assays for minimal disseminated disease analysis in rhabdomyosarcoma (RMS).
- To apply the hypermethylation assays to a series of bone marrow specimens from RMS patients.
OUTLINE: Archived tumor, bone marrow, and peripheral blood samples are analyzed for DNA hypermethylation by PCR-based assays and microarray assays. Results are then compared with each patient's clinical and pathological characteristics, and outcomes. Patterns of locus hypermethylation in tumor and paired bone marrow samples are also compared.
