Combination Chemotherapy in Treating Patients With Burkitt's Lymphoma or Burkitt's Leukemia
|ClinicalTrials.gov Identifier: NCT00040690|

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.
PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have Burkitt's lymphoma or Burkitt's leukemia.
|Condition or disease||Intervention/treatment||Phase|
|Leukemia Lymphoma||Biological: filgrastim Drug: cyclophosphamide Drug: cytarabine Drug: doxorubicin hydrochloride Drug: etoposide Drug: ifosfamide Drug: leucovorin calcium Drug: methotrexate Drug: vincristine sulfate Radiation: radiation therapy||Phase 2|
Hide Detailed Description
- Describe the morphology, phenotype, and cytogenetics, using fresh tumor tissue (when possible), in patients with Burkitt's or Burkitt-like lymphoma/leukemia treated with the CODOX-M chemotherapy regimen (cyclophosphamide, vincristine, doxorubicin, and methotrexate) alone or alternating with the IVAC chemotherapy regimen (ifosfamide, etoposide, and cytarabine).
- Determine whether cytogenetic and molecular changes are associated with or predictable from the immunophenotype of the tumor cells or patient characteristics (e.g., age).
- Examine the relationship between t(14;18) and bcl-2 expression in patients treated with this regimen.
- Determine whether the presence of specific cytogenetic and molecular changes, in particular the presence of t(14;18) and t(8;14), is associated with an adverse outcome (progression-free and overall survival) in patients treated with this regimen.
- Assess the activity of the alternating CODOX-M/IVAC chemotherapy regimens using a lower dose of methotrexate (compared to the UKLG LY06 trial) in these patients.
- Assess further the activity of these regimens in patients with leukemic Burkitt's lymphoma.
- Modify the chemotherapy doses in these regimens to include older patients who are often excluded from clinical trials.
OUTLINE: This is a multicenter study. Patients with low-risk disease are assigned to group A, while patients with high-risk disease are assigned to group B.
Group A (low-risk group):
- Patients receive 3 courses of the CODOX-M chemotherapy regimen comprising cyclophosphamide IV on days 1-5, vincristine IV on days 1 and 8, doxorubicin IV on day 1, and methotrexate (MTX) IV over 24 hours on day 10. Patients over age 65 receive reduced-dose MTX on day 10. All patients receive leucovorin calcium (CF) IV once at hour 36 after initiation of MTX infusion, once every 3 hours between hours 36-48, and continuing once every 6 hours until blood levels of MTX are safe. Patients also receive filgrastim (G-CSF) subcutaneously (SC) once daily beginning on day 13 and continuing until blood counts recover.
- During all 3 courses of the CODOX-M regimen, patients receive CNS prophylaxis comprising cytarabine (ARA-C) intrathecally (IT) on days 1 and 3, MTX IT on day 15, and oral CF (24 hours after IT MTX) on day 16.
Group B (high-risk group):
- Patients receive the CODOX-M chemotherapy regimen (as above) alternating with the IVAC chemotherapy regimen (as defined below) for a total of 4 courses given in the following sequence: CODOX-M, IVAC, CODOX-M, and IVAC. The IVAC chemotherapy regimen comprises ifosfamide (IFF) IV over 1 hour and etoposide IV over 1 hour on days 1-5 and ARA-C IV over 3 hours on days 1 and 2. Patients over age 65 receive reduced-dose IFF and ARA-C. Patients also receive G-CSF SC once daily beginning on day 7 and continuing until blood counts recover.
- During IVAC, patients without CNS disease receive MTX IT on day 5 and oral CF (24 hours after MTX). Patients with proven CNS disease receive intensified IT therapy throughout the first two courses of CODOX-M/IVAC chemotherapy.
For patients in group B with CNS disease at diagnosis, radiotherapy is only considered in the presence of a cerebral mass documented by CT scan or MRI. Patients in group A or B who develop isolated CNS recurrence (documented by malignant CSF pleocytosis, cranial nerve palsies, or both) at any time after the first course of study therapy receive the same CNS treatment (as above) as patients with proven CNS disease in addition to whole brain irradiation for 3 weeks.
Patients are followed monthly for 4 months, every 2 months for 8 months, every 3 months for 1 year, every 4 months for 1 year, every 6 months for 1 year, and then annually thereafter.
PROJECTED ACCRUAL: A minimum of 120 patients (30 with low-risk disease and 90 with high-risk disease) will be accrued for this study within approximately 3-4 years.
