Brief Summary: RATIONALE Diagnostic procedures such as genetic testing may improve the ability to detect acute lymphocytic leukemia and determine the extent of disease

PURPOSE Diagnostic study to try to detect changes in the genes of children who have been treated for relapsed acute lymphocytic leukemia
Detailed Description: OBJECTIVES

Determine the incidence of p16p15 homozygous deletions and p15 promoter hypermethylation in acute lymphocytic leukemia cells of children treated on protocol CCG-1941
Determine the prognostic importance of p16p15 abnormalities in these children
Determine the presence or absence of p16p15 abnormalities in the dominant clone at diagnosis if present at relapse in these patients

OUTLINE Frozen cells are obtained from samples collected on protocol CCG-1941 DNA is isolated and examined using Southern blot analysis to assay for deletions and promoter hypermethylation of p16 andor p15

PROJECTED ACCRUAL Approximately 100 samples will be obtained for this study
