New hope for young leukemia patients: combination chemo shows promise

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Eligibility Criteria: 1. Diagnosis 1. Newly diagnosed patients with either B-precursor or T-precursor acute lymphoblastic leukemia (WHO criteria). Burkitt type leukemia as defined per protocol is not eligible. Patients known to have Ph+ ALL at time of diagnosis are not eligible. 2. CALGB patients entered on CALGB 10403 who are later found to meet the following criteria for Ph+ ALL should have treatment on this trial discontinued and should be encouraged to enroll on CALGB 10001 or its successor trial: * BCR-ABL fusion transcript determined by FISH or RT-PCR * t(9;22)(q34;q11) or variant determined by cytogenetics Non-CALGB study participants who are later found to be Ph+ should have treatment on this trial discontinued and should be encouraged to enroll on an appropriate clinical trial specifically designed for Ph+ ALL. 2. Age: 16 - 39 years 3. ECOG Performance Status 0-2 4. Patients with Down Syndrome are excluded from this study due to the likelihood of excessive toxicity resulting. These patients should be treated in consultation with a pediatric oncologist. 5. Prior Therapy - No prior therapy except for limited treatment with corticosteroids or hydroxyurea and a single dose of intrathecal cytarabine. 1. No prior therapy for acute leukemia except emergency therapy (corticosteroids or hydroxyurea) for blast cell crisis, superior vena cava syndrome, or renal failure due to leukemic infiltration of the kidneys. When indicated, leukapheresis or exchange transfusion is recommended to reduce the WBC. 2. Single-dose intrathecal cytarabine is allowed prior to registration or prior to initiation of systemic therapy 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. Systemic chemotherapy must begin within 72 hours of this intrathecal therapy. 3. Patients receiving prior steroid therapy are eligible for study. The dose and duration of previous steroid therapy should be carefully documented on case report forms.
