Study Subtype: Ancillary/Correlative Observational Study Model: Cohort Time Perspective: Retrospective Biospecimen Retention: Samples With DNA Biospecimen Description: Tissue Study Population Description: Existing NRSTS samples from the COG D9902/ARST0332 studies Sampling Method: Non-Probability Sample
I. To determine the frequency with which actionable mutations are found in archived non-rhabdomyosarcoma soft tissue sarcoma (NRSTS) tumor specimens using mass spectrometry (MS) analysis of tumor-derived deoxyribonucleic acid (DNA).
Archived DNA tissue samples are analyzed for frequency of genetic mutations, including single nucleotide polymorphisms (SNPs), single nucleotide variants (SNVs), and small deletions and/or insertions, by polymerase chain reaction (PCR) and mass spectometry (Sequenom MassARRAY). Results are then analyzed to determine whether specific mutations correlate with patient or disease features such as tumor stage, histological grade, or outcome.

Archived DNA tissue samples are analyzed for frequency of genetic mutations, including SNPs, SNVs, and small deletions and/or insertions, by PCR and mass spectometry (Sequenom MassARRAY). Results are then analyzed to determine whether specific mutations correlate with patient or disease features such as tumor stage, histological grade, or outcome.
Other: laboratory biomarker analysis
- Frequency of individual mutated genes in patients with NRSTS [ Time Frame: Up to 1 month ]
- Genetic changes that are most common and likely to have the greatest therapeutic impact [ Time Frame: Up to 1 month ]
Biospecimen Retention: Samples With DNA
