Implication

Expert consensus demonstrates standardized morphological criteria for blasts and ring sideroblasts in myelodysplastic syndrome, highlighting improved diagnostic accuracy.

Key Points

To establish standardized morphological definitions and enumeration criteria for blast cells and ring sideroblasts across all myelodysplastic syndrome subtypes.
An international panel of expert hematopathologists and hematologists reviewed bone marrow morphology across all myelodysplastic syndrome subtypes.
The working group developed consensus criteria to refine French-American-British and World Health Organization morphological classifications.
Recommended defining blasts as either agranular or granular, replacing previous type I, II, and III classifications while strictly separating dysplastic promyelocytes.
Defined ring sideroblasts as erythroblasts containing at least five siderotic granules covering a minimum of one-third of the nuclear circumference.
Advised counting a sufficient number of cells to ensure accurate blast percentages, particularly around critical diagnostic and prognostic thresholds.
