Abstract

4485 Purpose Thanks to the development of knowledge in the field of molecular biology, the great progress has been done in risk stratification of patients with acute myeloid leukemia (AML) at diagnosis, in recent years. Based on the recommendations of international expert groups there were identified the patients who may benefit from the allogeneic stem cell transplantation (allo-SCT) as a consolidation of first complete remission (CR). In the absence of an universal marker for minimal residual disease (MRD) measurements, there is still little information about the importance of MRD prior to allo-SCT. Our department has a very good experience with quantitative monitoring of WT1 gene expression as a marker of MRD during treatment of AML. The aim was to retrospectively evaluate the significance of MRD in patients indicated for allo-SCT in 1.CR. Patients and methods Overall 35 patients (pts) in the first morphological CR were transplanted from April 2005 - July 2011. Median age was 46 ...
