Clonal dynamic changes during the progression of myelodysplastic neoplasms to secondary acute myeloid leukemia: a paired-sample comparison.
Mutations in specific genes reliably signal when myelodysplastic syndrome is transforming into acute leukemia, enabling earlier intervention.
This retrospective study analyzed 79 paired bone marrow samples from the same patients at MDS diagnosis and subsequent sAML transformation, sequencing 32 genes commonly mutated in myeloid neoplasms. Acquisition of signaling pathway mutations (e.g., RAS/FLT3) and transcription factor mutations (notably RUNX1) were hallmarks of MDS-to-sAML progression, while epigenetic and spliceosome mutations were stable—a pattern independent of BM blast count at MDS or speed of progression.

Why it surfaced
Largest paired MDS→sAML clonal dynamics dataset to date using comprehensive NGS panel. Defines which mutation classes drive transformation, providing predictive biomarker rationale. Direct relevance to MDS monitoring and early intervention strategies.
