Prospective feasibility of a minimal BH3 profiling assay in acute myeloid leukemia.
Cytometry B Clin Cytom
November 2024
BH3 profiling can assess global mitochondrial priming and dependence of leukemic cells on specific BH3 anti-apoptotic proteins such as BCL-2. In acute myeloid leukemia (AML), proof-of-concept prognostic studies have been performed on archived samples variably accounting for molecular genetics. We undertook a single-center feasibility study of a simplified flow-based assay to determine the absolute mitochondrial priming and BCL-2 dependence in consecutive AML patients.

- Despite initial treatment with midostaurin (MIDO) and chemotherapy in FLT3-mutated acute myeloid leukemia (AML), many patients face relapses, with complete remission rates around 60-70% and over 40% relapsing.
- A study of 150 patients with refractory/relapsed (R/R) AML revealed that those treated with MIDO showed lower persistence of FLT3-ITD mutations compared to those who did not receive MIDO (68% vs. 87.5%).
- The study found that detecting multiple FLT3-ITD clones at diagnosis related to a higher persistence rate of these mutations at relapse, indicating the need for sensitive techniques in FLT3-
Purpose: The use of inotuzumab ozogamicin (InO), a conjugated anti-CD22 monoclonal antibody, is becoming a promising frontline treatment for older patients with ALL.
Patients And Methods: EWALL-INO is an open-label prospective multicenter phase II trial (ClinicalTrials.gov identifier: NCT03249870).
Article Synopsis
- The European LeukemiaNet (ELN) previously created genetic risk classifications using data from younger adults who underwent intensive chemotherapy.
- New research has emerged analyzing patients who receive less-intensive therapies, highlighting the need for tailored classifications.
- This has led to a proposal for a new ELN genetic risk classification specifically designed for patients undergoing these alternative treatment options.
Purpose: quantification is widely regarded as the standard for monitoring measurable residual disease (MRD) in Philadelphia chromosome-positive (Ph+) ALL. However, recent evidence of multilineage involvement questions the significance of MRD. We aimed to define the prognostic role of MRD as assessed by or lymphoid-specific immunoglobulin/T-cell receptor () gene markers.
