Combination Chemotherapy in Treating Patients With Acute Lymphoblastic Leukemia or Advanced Lymphoblastic Non-Hodgkin's Lymphoma

Intensive Treatment For T-CELL Acute Lymphoblastic Leukemia and Advanced Stage Lymphoblastic Non-Hodgkin's Lymphoma: A Pediatric Oncology Group Phase III Study

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. Dexrazoxane may lessen the side effects of chemotherapy. PURPOSE: Randomized phase III trial to compare combination chemotherapy with or without dexrazoxane and with or without high-dose methotrexate in patients with acute lymphoblastic leukemia or advanced lymphoblastic non-Hodgkin's lymphoma.

OBJECTIVES: I. Determine, in a randomized trial, the effectiveness of high-dose methotrexate when added to a multiagent chemotherapy backbone (the Dana Farber Cancer Institute regimen, protocol DFCI-87001) proven effective in T-cell acute lymphoblastic leukemia (T-ALL) and advanced lymphoblastic non-Hodgkin's lymphoma (NHL). II. Determine the role of dexrazoxane in preventing cardiotoxicity in children with T-ALL and advanced lymphoblastic NHL treated with an anthracycline-based regimen. III. Study the biology of T-cell lymphoid malignancies by accumulating data on the concurrent ALL classification study (POG-9400) and analyzing the data relative to outcome. IV. Evaluate the correlation of minimal residual disease (using the TAL 1 proto-oncogene) with event-free survival. V. Determine the role of p53 and p16 tumor suppressor genes in T-ALL. VI. Determine whether drug sensitivity profiles of blast cells to doxorubicin, methotrexate, and cytarabine correlate with initial response and subsequent relapse. OUTLINE: This is a randomized, multicenter study. Patients are stratified according to disease category (acute lymphoblastic leukemia (ALL) with no CNS disease vs. ALL with CNS disease vs. non-Hodgkin's lymphoma (NHL) with no CNS disease vs. NHL with CNS disease), gender, race (Caucasian vs. African American vs. Hispanic). Patients are randomized to one of four treatment arms. ARM I: During induction therapy, patients receive vincristine IV once daily on days 1, 8, 15, and 22, oral prednisone three times a day on days 1-21, doxorubicin IV daily on days 1, 2, and 22, methotrexate IV once, at least 8 hours after doxorubicin on day 2, and oral mercaptopurine daily on days 22-35. Patients receive triple intrathecal therapy (TIT) consisting of methotrexate, cytarabine, and hydrocortisone on weeks 1, 3, 4, 5, and 6. Patients with CNS 2 or 3 disease receive TIT on week 2. During weeks 7-33, patients receive consolidation therapy consisting of vincristine IV once every 3 weeks, oral prednisone three times a day over 5 days, every 3 weeks, doxorubicin IV once every 3 weeks, oral mercaptopurine daily for 14 days, every 3 weeks, and asparaginase intramuscularly (IM) weekly on weeks 7-26. Patients receive TIT on week 10 and 22 (on week 16 for patients with CNS 2 or 3 disease). Patients receive radiotherapy beginning on week 22. During weeks 34-108, patients receive continuation therapy consisting of vincristine IV once every 3 weeks, oral prednisone three times a day over 5 days, every 3 weeks, methotrexate IV or IM weekly (omitted during TIT) and oral mercaptopurine daily for 14 days, every 3 weeks. Patients receive TIT on weeks 40, 58, 76, and 94. Arm II: Patients receive induction therapy as in Arm I with an addition of dexrazoxane IV given prior to doxorubicin on days 1, 2, and 22. Patients receive consolidation therapy as in Arm I with an addition of dexrazoxane IV given prior to doxorubicin once every 3 weeks. Patients receive continuation therapy as in Arm I. Arm III: Patients receive induction therapy as in Arm I in addition to high dose methotrexate IV on week 4 and leucovorin calcium IV or orally every 6 hours for 7 doses beginning 36 hours after high dose methotrexate. Patients receive consolidation therapy as in Arm I in addition to high dose methotrexate IV on weeks 7, 10, and 13 followed by leucovorin calcium as in induction therapy. Patients receive continuation therapy as in Arm I. Arm IV: Patients receive induction therapy and consolidation therapy as in Arms I, II, and III. Patients receive continuation therapy as in Arm I. Treatment continues for up to 108 weeks in the absence of disease progression or unacceptable toxicity. Patients are followed every 2 months for 1 year, every 4 months for 3 years, then every 6 months for 2 years. PROJECTED ACCRUAL: A total of 494 patients will be accrued for this study.

Since all patients receive the same induction, the endpoint will be CCR , i.e. complete continuous remission (the time to failure for any cause among patients achieving a complete response)

Endpoint will be abnormalities in the 31 week and the year 3 echocardiograms (i.e. year 1 off therapy). Secondarily, we shall compare the CCR rates for the two treatment regimens, in a two sided fashion.
