RATIONALE: Studying samples of blood and tumor 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 study is studying genes in samples from younger patients with desmoplastic small round cell tumor registered on COG-D9902 or COG-ABTR01B1.

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

Primary Outcome Measures:
  • Identification of novel mutations, single nucleotide polymorphisms, and copy number changes associated with DSRCT [ Designated as safety issue: No ]
  • Identification of genomic regions involved in pathogenesis of DSRCT [ Designated as safety issue: No ]

Estimated Enrollment: 20
Study Start Date: September 2011
Estimated Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Detailed Description:


  • To perform whole-exome sequencing on desmoplastic small round cell tumor (DSRCT) samples and their available matched normal samples to identify novel mutations, single nucleotide polymorphisms, or copy number changes associated with these tumors.
  • To identify regions of interest that may be involved in the pathogenesis (including the region of EWSR1-WT1 translocation) from the whole-exome sequencing and perform detailed resequencing and transcriptone sequencing to further define the molecular aberrations at the RNA level.

OUTLINE: This is a multicenter study.

Archived tumor tissue samples are analyzed for DNA sequencing, effects of RNA on gene expression levels, novel RNA isoforms, splice variants, and translocations.
