About this trial

* Clinical and genetic factors consistent with High risk : Induction → Consolidation

1. BM MRD \< 0.01% : IM #1 → DI #1 → IM #2 → Maintenance 2. BM MRD ≥ 0.01% : IM #1 → DI #1 → IM #2 → DI #2 → Maintenance 3. BM MRD ≥ 0.01% after Consolidation

<!-- -->

1. T cell ALL : Change to very high risk regimen 2. Pre-B ALL : IM #1 → Intensification

1. BM MRD \&lt; 0.01% after IM #1 : DI #1 → IM #2 → DI #2 → Maintenance 2. BM MRD ≥ 0.01% after IM #1 : Change to Very high risk regimen

* Difference in the number of \&#39;interim maintenance(IM)\&#39; and \&#39;delayed intensification(DI)\&#39; is important for chemotherapies based on MRD.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age: 1year~19years of age at diagnosis

Patients who are newly diagnosed Pre-B ALL and meet one of the following criteria

High-risk group according to the National Cancer Institute (NCI)/Rome: Age greater than or equal to 10 years and less than 19 years at diagnosis, or white blood cell count greater than or equal to 50 x 10^9/L at diagnosis

If extra-bone marrow lesions are identified at the time of diagnosis, Central nervous system involvement (CNS3) or testicular involvement

Disqualifiers

Patients with Burkitt leukemia/lymphoma or mature B-cell leukemia

Patients with Down syndrome

potential of pregnancy or during pregnancy (patients of childbearing age need adequate contraception for the duration of the trial)

Patients who have already received steroid treatment for newly diagnosed ALL specified in the above selection criteria or chemotherapies more than one intrathecal cytarabine treatment

Trial design

    Intervention Description : * Clinical and genetic factors consistent with High risk : Induction → Consolidation 1. BM MRD \&lt; 0.01% after both Induction and Consolidation : IM #1 → DI #1 → IM #2 → Maintenance 2. BM MRD ≥ 0.01% after Induction, \&lt; 0.01% after Consolidation : IM #1 → DI #1 → IM #2 → DI #2 → Maintenance 3. BM MRD ≥ 0.01% after Consolidation <!-- --> 1. T cell ALL : Change to very high risk regimen 2. Pre-B ALL : IM #1 → Intensification 1. BM MRD \&lt; 0.01% after IM #1 : Continue with \&#39;No. 2\&#39; of High risk regimen starting with DI #1 2. BM MRD ≥ 0.01% after IM #1 : Change to Very high risk regimen * T cell ALL patients with M1 BM post-Consolidation will start IM #1. However, the patients will switch to Very high risk regimen at the next chemotherapy cycle once post-Consolidation MRD ≥ 0.01% has been reported.
