Auer rod positive dysmyelopoietic syndrome
American Journal of Hematology
|December 1, 1981
Summary
Auer rod-positive refractory anemia with excess blasts (RAEB) is a morphological variant with a similar clinical course and survival to Auer rod-negative RAEB. Separate treatment approaches for Auer rod-positive RAEB are not advised.
Area of Science:
- Hematology
- Oncology
- Pathology
Background:
- Refractory anemia with excess blasts (RAEB) is a myelodysplastic syndrome characterized by bone marrow failure.
- The prognostic significance of Auer rods in RAEB requires further elucidation.
Observation:
- Five of 25 RAEB patients exhibited Auer rods in myeloblasts.
- Auer rod-positive RAEB patients had a median survival of 14 months post-diagnosis.
- Auer rod-negative RAEB patients had a median survival of 12 months.
Findings:
- The clinical course for both Auer rod-positive and negative RAEB involved progressive bone marrow failure.
- Two patients developed acute leukemia, both from the Auer rod-negative group.
- Survival outcomes were comparable between Auer rod-positive and negative RAEB groups.
Implications:
- Auer rod-positive RAEB represents a morphologic variant of RAEB with a similar prognosis.
- Current treatment strategies for RAEB do not require modification for Auer rod-positive cases.
- Further research into dysmyelopoietic syndromes and their specific morphological variants is warranted.
