BM MRD ≥ 0.01% after IM #1 : Change to Very high risk regimen * Difference in the number of \'interim maintenance(IM)\' and \'delayed intensification(DI)\' is important for chemotherapies based on MRD.
* Clinical and genetic factors consistent with High risk : Induction → Consolidation 1. BM MRD \< 0.01% after both Induction and Consolidation : IM #1 → DI #1 → IM #2 → Maintenance 2. BM MRD ≥ 0.01% after Induction, \< 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 \< 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 * 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.

BM MRD \< 0.01% after both Induction and Consolidation : IM #1 → DI #1 → IM #2 → Maintenance 2. BM MRD ≥ 0.01% after Induction, \< 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 \< 0.01% after IM #1 : Continue with \'No. 2\' 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.
