Abstract

4894 Background: Pretreatment karyotypes of leukemic cells provide the core for risk-stratification schemes in acute myeloid leukemia (AML) and cytogenetic abnormalities are well established as the strongest prognostic factor for response to therapy and for survival in AML patients. Several cytogenetic risk classifications have been built to stratify AML patients. Only the recent European Leukemia Net (ELN) recommendations by an international panel proposed a new standardized cytogenetic reporting system for AML. More importantly, few studies attempted so far to validate the ELN requirements for risk assessment in AML patients treated with allogeneic hematopoietic stem cell transplantation (HSCT). We investigated whether our series of adult AML patients treated with HSCT could validate the ELN classification criteria. We also assessed the prognostic value of this new risk stratification scheme. Methods: ELN cytogenetic reporting criteria were applied to a series of 110 adult AML pat...
