combination chemotherapy in treating patients with acute b-lymphoblastic leukemia or non-hodgkin's lymphoma

Conditions: Leukemia; Lymphoma

Summary: 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 cancer cells. purpose: phase ii trial to study the effectiveness of combination chemotherapy in treating patients who have acute b-lymphoblastic leukemia or recurrent non-hodgkin's lymphoma.

objectives: i. improve the survival of children and adolescents with poor-risk nonlymphoblastic lymphoma and acute b-lymphoblastic leukemia using an intensive, short-course regimen of combination chemotherapy. ii. assess the toxicity of the regimen. outline: nonrandomized study. induction: 7-drug combination chemotherapy with leucovorin rescue plus triple intrathecal therapy (tit). cyclophosphamide, ctx, nsc-26271; thiotepa, tspa, nsc-6396; vincristine, vcr, nsc-67574; daunorubicin, dnr, nsc-82151; dexamethasone, dm, nsc-34521; etoposide, vp-16, nsc-141540; methotrexate, mtx, nsc-740; with leucovorin calcium, citrovorum factor, cf, nsc-3590; plus tit: it mtx; it cytarabine, it ara-c, nsc-63878; it hydrocortisone, it hc, nsc-10483. consolidation: 6-drug combination chemotherapy with leucovorin rescue plus tit. ara-c; vp-16; asparaginase (e. coli), asp, nsc-109229; mtx; vcr; methylprednisolone, meprdl, nsc-19987; with cf; plus tit. reinduction: 7-drug combination chemotherapy with leucovorin rescue plus tit. ctx; tspa; vcr; dnr; dm; vp-16; mtx; with cf; plus tit. projected accrual: a maximum of 30 patients, accrued from 4 institutions, will be entered. if at any time more than 3 patients are not "event free", the trial will be terminated early, with patients considered event free if they enter remission, do not die as a result of treatment toxicity, and do not experience progression within 1 year from the start of therapy.

Eligibility criteria:
disease characteristics: newly diagnosed undifferentiated nonlymphoblastic non-hodgkin's lymphoma (burkitt's or non-burkitt's) newly diagnosed large cell lymphoma with cns involvement recurrent non-hodgkin's lymphoma l-3 and b-cell leukemia included at least 1 of the following required: ldh at least 500 iu/liter (old method) or 2,000 iu/liter (new method) bone marrow involvement (greater than 5% lymphoblasts) cns involvement (lymphoblasts on csf cytospin or intracranial mass on ct or mri scan) patient characteristics: age: any age performance status: not specified hematopoietic: not specified hepatic: not specified renal: not specified prior concurrent therapy: prior therapy allowed for non-hodgkin's lymphoma no prior therapy for all other diseases
