Summary
Brief summary (as posted)
RATIONALE: Determination of genetic markers for soft tissue sarcoma or rhabdomyosarcoma may help doctors identify patients who are at risk for therapy-related leukemia. PURPOSE: Clinical trial to study genetic testing of children with soft tissue sarcoma or rhabdomyosarcoma to identify children who are at risk of developing leukemia from the chemotherapy used to treat sarcoma.

- Identification of Genetical suceptibility prior to therapy
- description
- Determine the glutathione-s-transferase theta (GSTT1) or glutathione-s-transferase mu (GSTM1) null genotype is more frequent in individuals with t-MDS/AML. Determine the GSTT1 or GSTM1 null genotype is associated with a reduced incidence of relapse of sarcoma. Determine NAT2 or CYP1A1 genotype influences risk of t-MDS/AML. Determine development of a "mutator phenotype" as demonstrated by developing microsatellite instability is an early marker of individuals likely to progress to t-MDS/AML.

- Increased Risk Of T-MDS/AML before/after Therapy
- description
- Determine clonal hematopoiesis develops in children receiving high intensity alkylating agent chemotherapy for sarcomas. Determine development of clonal hematopoiesis is associated with increased frequency of t-MDS/AML. Determine measurement of somatic cell mutation frequency, measured by the glycophorin A (GPA) assay prior to and after chemotherapy will predict individuals at increased risk of t-MDS/AML. Identify individuals with ras gene mutations in normal peripheral blood cells after therapy, and whether the identification of such mutations is associated with increased risk of t-MDS/AML blood cells after therapy, and whether the identification of such mutations is associated with increased risk of t-MDS/AML.
