Name Description
Refractory anemia
  • Less than 5% primitive blood cells (myeloblasts) in the bone marrow and pathological abnormalities primarily seen in red cell precursors.
Refractory anemia with ring sideroblasts (RARS)|
  • Less than 5% myeloblasts in the bone marrow, but distinguished by the presence of 15% or greater red cell precursors in the marrow being abnormal iron-stuffed cells called ringed sideroblasts.
Refractory anemia with excess blasts (RAEB)
  • 5-20% myeloblasts in the marrow.
Refractory anemia with excess blasts in transformation (RAEB-T)
  • 21-30% myeloblasts in the marrow (>30% blasts is defined as acute myeloid leukemia).
Chronic myelomonocytic leukemia (CMML)
  • Less than 20% myeloblasts in the bone marrow and greater than 1*109/L monocytes in peripheral blood.
