August 6, 2023 updated by: Nanfang Hospital, Southern Medical University

Risk Stratification-directed Therapy for Acute Myeloid Leukemia With t(8;21) /AML1-ETO-positive

Acute myeloid leukemia with t(8;21) /AML1-ETO-positive (AE AML) is a heterogeneous disease entailing different prognoses. There were significant differences in the therapeutic effect between different subgroups of AE AML. Therefore, risk stratification-directed therapy is very necessary for AE AML.

Detailed Description

Acute myeloid leukemia with t(8;21) /AML1-ETO-positive (AE AML) is a heterogeneous disease entailing different prognoses.There were significant differences in the therapeutic effect between different subgroups of AE AML. For example, patients with c-kit mutation had higher relapse rate and lower overall survival, compared with those without c-kit mutation. Therefore, risk stratification-directed therapy is very necessary for AE AML. The purpose of this study is to establish risk stratification-directed therapy for AE AML.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Non-Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Low risk group
Patients with KIT-ASXL1- (non-mutation, NM) and acquiring main molecular response (MMR) after two cycles of consolidation.
Other: Consolidation with chemotherapy (CT) or autologous hematopoietic stem cell transplantation (auto-HSCT)

For CT, patients were treated with high dose cytarabine (HDAC), cytarabine at a dosage of 1-3 g/m2 q12 h ×6 doses, for 4-6 cycles.

For auto-HSCT, patients were treated with 3 cycles of HDAC and then bridged to auto-HSCT.
Experimental: Intermediate risk group
Patients with KIT+/ASXL1+ (single mutation, 1M) and acquiring MMR after two cycles of consolidation.
Other: Consolidation with auto-HSCT or HLA-matched HSCT

For auto-HSCT, patients were treated with 3 cycles of HDAC and then bridged to auto-HSCT.

For HLA-matched HSCT, patients were treated with 1-2 cycles of HDAC and then bridged to HLA-matched HSCT. HLA-matched donors were available in these patients.
Experimental: High risk group
Patients with KIT+ASXL1+ (two mutations ,2M) or without acquiring MMR after two cycles of consolidation.
Other: allogeneic HSCT
For allogeneic HSCT, patients were treated with 1-2 cycles of HDAC and then bridged to allogeneic HSCT, including HLA-matched and haploidentical transplantation.
