Clinical Research Studies

Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

• Conditions:
  Acute Lymphoblastic Leukaemia [all]
• Age: Between None - None
• Gender: Male or Female

• Other Inclusion Criteria:
  

  T-ALL patients must be enrolled on AALL08B1 prior to treatment and enrollment on AALL0434 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:
  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 Prior therapy restrictions
  Patients shall have had no prior cytotoxic chemotherapy with the exception of steroids and/or IT cytarabine IT 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 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 For the management of airway compromise, patients who have received emergent chest irradiation up to 600 cGy will be eligible for this study

  
  

You may not be eligible for this study if the following are true:

• Pregnant or lactating females are ineligible Patients with Down syndrome are ineligible to enroll onto this study For T-NHL patients the following additional exclusion criteria apply: B-precursor lymphoblastic lymphoma
  Morphologically unclassifiable lymphoma Absence of both B-cell and T-cell phenotype markers in a case submitted as lymphoblastic lymphoma CNS3-positive or testicular involvement
