Analyses of Mutations Associated With Secondary Leukemia or Non-Hodgkin's Lymphoma in Patients Treated for Hodgkin's Disease or Childhood Brain Tumors
OBJECTIVES: I. Determine the frequency of chromosome 3, 11, and 21 aberrations in peripheral
blood lymphocytes (PBL) specifically associated with acute myelogenous leukemia in patients
with adult or pediatric Hodgkin's disease treated with radiotherapy and/or chemotherapy. II.
Determine the frequency of these aberrations in patients with pediatric central nervous
system tumors treated with radiotherapy and/or chemotherapy. III. Determine the
glutathione-S-transferase allotype, associated with human toxicological response to
carcinogen exposure, for these patients. IV. Determine the frequency of t(14;18) gene
rearrangement, associated with deregulation of the bcl-2 proto-oncogene in non-Hodgkin's
lymphoma, in PBL of these patients.
OUTLINE: An extra tube of blood is collected before, every 4 weeks during, and every 3
months after radiotherapy and/or chemotherapy. DNA is isolated from the blood sample and the
GSTM1, GSTT1, and various cytochrome P (CYP) 450 genotypes are determined by polymerase
chain reaction (PCR). Mononuclear leukocytes are analyzed for chromosome aberrations on
chromosome numbers 3, 11, and 21. Pretreatment karyotype and frequency of translocations are
determined for each patient. Peripheral blood lymphocyte DNA is also examined for t(14;18)
gene rearrangements.
PROJECTED ACCRUAL: A total of 50 patients will be accrued for this study within 2 years.
