Although the patient presented with highly complex chromosomal abnormalities, his initial clinical presentation was that of typical refractory anemia with excess blasts. Shortly after diagnosis (7 months), the patient developed acute leukemia. [ncbi.nlm.nih.gov]

  The 5q- associated with RAEB and other preleukemic syndromes was present in 100% of the cells; however, 60% of the cells had a highly unusual derivative chromosome involving the short arm of chromosome 1 and the long arm of chromosome 5, i.e., t(1;5) [ncbi.nlm.nih.gov]

• Suggestibility

  It is suggested that imbalance in immunoregulatory T cells, which has a crucial role in the control of hemopoiesis, may be a primary event in the pathogenesis of myelodysplastic syndrome which eventually develops into an overt leukemia. [mdanderson.influuent.utsystem.edu]

  This result suggests that t(6;9) represents one of the pathways from MDS to leukemia in patients with ANLL. [ncbi.nlm.nih.gov]

When patients have neutropenia or thrombocytopenia without excess blasts in the marrow, it is possible that the pathophysiology could be T-cell mediated in patients with MDS that do not have excessive blasts. [businessandleadership.com]

It will nevertheless, be necessary to compare our results to other MDS subgroups to determine whether the decrease of the RBP4 plasma level is related to MDS pathophysiology specific for RAEB-1, or if it is a result of inflammation, as the RBP4 is a negative [link.springer.com]
