Brief summary
This partially randomized phase III trial studies the side effects of different combinations of risk-adapted chemotherapy regimens and how well they work in treating younger patients with newly diagnosed standard-risk acute lymphoblastic leukemia or B-lineage lymphoblastic lymphoma that is found only in the tissue or organ where it began (localized). Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy), giving the drugs in different doses, and giving the drugs in different combinations may kill more cancer cells.
Detailed description
PRIMARY OBJECTIVES: l. To determine if a maintenance regimen containing weekly oral methotrexate at 40 mg/m\^2/week will result in an improved disease free survival (DFS) compared to that containing weekly oral methotrexate at 20 mg/m\^2/week in the average-risk (AR) subset of patients with standard-risk B-precursor acute lymphoblastic leukemia (ALL). (Complete effective January 13, 2017) II. To determine whether a reduced-pulses maintenance regimen with vincristine (vincristine sulfate)/dexamethasone pulses delivered every 12 weeks can be used without adversely impacting DFS as compared to pulses given every 4 weeks in the AR subset of patients with standard risk B-precursor ALL. III. To confirm that patients in the low-risk (LR) subset of standard risk B-precursor ALL, based on clinical and cytogenetic features and minimal residual disease (MRD) criteria, can attain a 5 year DFS of at least 95% with either a P9904 based regimen that includes 6 courses of intermediate dose (1 g/m\^2 over 24 hours) methotrexate without alkylating agents or anthracyclines (Arm LR-M), or an outpatient based regimen identical to that of AR patients with reduced vincristine/dexamethasone pulses at 12 week intervals during maintenance (Arm LR-C). IV. To provide standardized treatment and enhanced supportive care to children with standard-risk (SR) Down syndrome B-ALL in order to improve outcomes and facilitate further study of this biologically and clinically unique patient subgroup. V. To improve understanding of the biology of localized B-lineage lymphoblastic lymphoma (B-LLy) and Down syndrome (DS) B-LLy by obtaining biologic data, including fluorescence in situ hybridization (FISH) for recurrent cytogenetic lesions on paraffin specimen, and banking tissue for future research. VI. To describe the 5-year event free survival (EFS) and overall survival (OS) of patients with Murphy stage I and II B-LLy receiving modified AR B-ALL therapy. SECONDARY OBJECTIVES: I. To assess the burden of AR B-ALL therapy as measured by surveys of the child's quality of life, missed days of school/daycare/work by children and parents, family functioning, parental perception of the child's health vulnerability, physical functioning, and emotional distress, 1) overall at different time points during and at the end of therapy, and by 2) comparing children randomized to every 4 week vs. every 12 week dexamethasone/vincristine pulses during maintenance. (Closed to accrual as of April 19, 2013) II. To characterize the onset, severity, and natural history of vincristine associated neuropathy by physical therapists (or occupational therapists) in children undergoing therapy for AR B-ALL, 1) overall at different time points during and at the end of therapy, and by 2) comparing children randomized to every 4 week vs. every 12 week dexamethasone/vincristine pulses during maintenance.
