Objectives
Narrative objectives1 1) To conduct a BFM backbone based nation-wide study and improve the treatment outcome of pediatric B cell precursor acute lymphoblastic leukemia in Japan
2) To establish the nation-wide assessment system of Minimal Residual disease (MRD). 80% of patients would be able to be evaluated the MRD.
3) To test the effectiveness of BFM-95 SR induction including two doses of DNR and DEX/VCR pulse in maintenance for SR patients.
4) To test the effectiveness and safety of intensive L-asaparaginase for IR patients.
5) Abolition of prophylactic cranial radiotherapy by intensive L-asaparaginase and exteded intrathecal therapy for HR patients. Comparison of BFM-HR block therapy vs VCR intensified BFM therapy.
6) To assess the patien'ts QOL in randomized arm in each risk group and search for the clinical parameters affecting patient's QOL.

Assessment
Primary outcomes Five years event free survival of each risk group
Key secondary outcomes 1) Five years event free survival, overall survival, and CNS relapse rate of whole group
2) Five years overall survival and CNS relapse rate of each risk group
3) Complete remission rate after induction (IA) and after early intensification (IB) of each risk group and whole group
4) Incidence of adverse events
5) Success rate of MRD estimation at time point 1 and time point 2. Correlation between MRD level and event free survival, overall survival
6) Estimation of quality of life (QOL) by Questionnaire survey to patients and families
7) Exploratory estimation of correlation between biological abnormality and prognosis
