Validation of Prognostic Markers for Very Low Risk Wilms Tumors
OBJECTIVES:
- To validate the utility of CUGBP2, HMGA2, and MEIS2 mRNA expression and 11p15
methylation to define a population of pediatric patients with very low risk Wilms tumor
(VLRWT) that have virtually no risk of relapse.
- To validate the utility of WT-1 mutation and 11p15 loss of heterozygosity analysis to
determine a population of VLRWT that have a higher risk of relapse when not treated
with chemotherapy.
- To validate the utility of NFYA, STRA6, TOB2, PDCD4, and SP3 mRNA expression to predict
relapse in VLRWT.
- To investigate the feasibility of broadening the definition of VLRWT through analysis
of stage I and II epithelial differentiated tumors registered on clinical trial
COG-Q9401 (NWTS-5) for CUGBP2, HMGA2, MEIS2, and 11p15 methylation.
OUTLINE: Previously banked tumor tissue samples are analyzed for mRNA expression of CUGBP2,
HMGA2, and MEIS2 via reverse-transcriptase (RT)-PCR and are classified as loss of
heterozygosity (LOH), loss of imprinting, or neither via 11p15 analysis. Samples are also
analyzed for WT-1 mutation via quantitative PCR and 11p LOH using 11p15 methylation analysis
and expression of NFYA, STRA6, TOB2, PDCD4, and SP3 via quantitative RT-PCR
