t-all or t-lineage lymphoblastic lymphoma
Item
patients must have newly diagnosed t-all or t-lineage lymphoblastic lymphoma (t-nhl) stage ii-iv; b-lineage lymphoblastic lymphoma will not be eligible for this study; a diagnosis of t-all is established when leukemic blasts lack myeloperoxidase or evidence of b-lineage derivation (cluster of differentiation [cd]19/cd22/cd20), and express either surface or cytoplasmic cd3 or two or more of the antigens cd8, cd7, cd5, cd4, cd2 or cd1a; if surface cd3 is expressed on all leukemic cells, additional markers of immaturity, including transmission disequilibrium test (tdt), cd34 or cd99 will be assessed for expression; cases with uncertain expression will receive additional review within the appropriate children's oncology group (cog) reference laboratory

t-nhl patients with tissue available for flow cytometry
Item
for t-nhl patients with tissue available for flow cytometry, the criterion for diagnosis should be analogous to t-all; for tissue processed by other means (i.e. paraffin blocks), the methodology and criteria for immunophenotypic analysis to establish the diagnosis of t-nhl defined by the submitting institution will be accepted

Item
patients shall have had no prior cytotoxic chemotherapy with the exception of steroids and/or it cytarabine
boolean
cytarabine
Item
if chemotherapy with cytarabine is allowed prior to registration for patient convenience; this is usually done at the time of the diagnostic bone marrow or venous line placement to avoid a second lumbar puncture; (note: the cns status must be determined based on a sample obtained prior to administration of any systemic or intrathecal chemotherapy, except for steroid pretreatment); systemic chemotherapy must begin within 72 hours of this it therapy

hyperleukocytosis or respiratory distress
Item
patients diagnosed as having t-nhl or t-all with respiratory distress or hyperleukocytosis may require steroids prior to the initiation of additional systemic therapy; they are eligible for aall0434 and will be stratified, based on the initial complete blood count (cbc); steroid pretreatment may alter the risk group assessment; if the t-all patient's clinical status precludes a lumbar puncture within 48 hours of the initiation of steroid therapy, t-all patients cannot be classified as low risk and will be intermediate or high risk based on the results of the day 29 marrow as above; patients with t-nhl who receive steroid pre-treatment will be classified as high risk; the dose and duration of previous steroid therapy should be carefully documented

emergent chest irradiation
Item

seizure
Item
patients with a prior seizure disorder requiring anti-convulsant therapy are not eligible to receive nelarabine; in addition, patients with pre-existing grade 2 (or greater) peripheral neurotoxicity, as determined prior to induction treatment by the treating physician or a neurologist, are not eligible to receive nelarabine; these restrictions in eligibility are designed to prevent excessive nelarabine-induced central and peripheral neurotoxicity in at-risk patients; for the purposes of this study, this includes any patient that has received anticonvulsant therapy to prevent/treat seizures in the prior two years
