Abstract :

Myeloproliferative neoplasms (MPNs) are clonal hematopoietic stem cell disorders characterized by proliferation of at least one hematopoietic lineage, with minimal defects in maturation. The emergence of next-generation sequencing (NGS) technique has expanded the genetic landscape of MPNs. As a result, most MPNs are now known to carry welldefined molecular abnormalities, such as BCR-ABL1 rearranged chronic myeloid leukemia (CML), JAK2-mutated polycythemia vera (PV), JAK2, CALR or MPL mutated essential thrombocythemia (ET) and primary myelofibrosis (PMF), and CSF3R-mutated chronic neutrophilic leukemia (CNL). In addition, somatic mutations in genes that regulate DNA methylation, histone modification, mRNA splicing, transcription, and signal transduction have been shown to play important roles in subsequent disease progression. We share our experience in clinical applications of molecular testing in the diagnosis, risk stratification, monitoring of measurable/minimal residual disease (MRD) and target therapy of MPNs in the NGS era.
