Fusion-harboring mast cells can explain molecular positivity in flow cytometric MRD-negative core-binding factor AML

Blood. 2024 Aug 1;144(5):581-585. doi: 10.1182/blood.2024024264.

Abstract

Molecular measurable residual disease can persist in core-binding factor acute myeloid leukemia in otherwise disease-free patients. Utilizing cell sorting followed by fluorescent in situ hybridization, we show that detection is due to mast cells.
