Survival and prognostic factors in Malaysian acute myeloid leukemia patients after allogeneic haematopoietic stem cell transplantation.

Studies of survival outcomes in acute myeloid leukemia (AML) patients treated with allogeneic haematopoietic stem cell transplantation (HSCT) are essential for planning patient care. The objectives of the present study were to determine overall survival (OS) and disease-free survival (DFS) in AML patients treated with allogeneic HSCT, and to identify prognostic factors associated with poor outcome. This study was conducted retrospectively, using data from the Blood and Bone Marrow Transplant, National Transplant Registry, Malaysia. All cases of AML treated with allogeneic HSCT registered at the registry between 1st January 1987 and 31st December 2010 were included in the study. A total of 300 patients were included for final analysis. The Kaplan-Meier method and Cox proportional hazard regression were used for statistical analysis. The overall 10-year OS and DFS for Malaysian AML patients after allogeneic HSCT were 63 and 67 %, respectively. Donor gender, marrow status, and conditioning intensity were identified as important prognostic factors for overall survival, whereas the significant prognostic factors for disease-free survival were ethnic group, donor gender, marrow status, and conditioning intensity. In conclusion, the survival outcomes for Malaysian AML patients treated with allogeneic HSCT were good, and this treatment should be considered the standard therapeutic approach for suitable candidates.
