Abstract

Unexplained blood cytopenias can be a clinical challenge for patients and clinicians alike. The relationship between these cytopenias and myeloid neoplasms like myelodysplastic syndromes (MDS) is currently an area of active research. There have been marked developments in our understanding of clonal hematopoiesis based on findings of somatic mutations in genes known to be associated with MDS. This has led to newer terms to describe precursor states to MDS, such as clonal hematopoiesis of indeterminate potential (CHIP) and clonal cytopenia of undetermined significance (CCUS). These conditions may allow earlier diagnosis, modify surveillance for MDS, and guide additional therapies. This review summarizes recent updates in the field for affected patients.
