Outcome and prognosis in acute myeloid leukemia patients treated with related peripheral blood hematopoietic stem cell transplantation / 中国实验血液学杂志

ABSTRACT

This study was purposed to evaluate the outcome of acute myeloid leukemia patients treated with related peripheral blood hematopoietic stem cell transplantation (PBHSCT) and analyse the potential prognostic factors. A total of 64 acute myeloid leukemia patients treated with related peripheral allo-HSCT from march 2008 to august 2012 in our hospital were enrolled in the analysis. All the patients received either HLA-matched related or mismatched related donor mobilized peripheral blood stem cells. All the patients were followed up and evaluated for overall survival (OS), leukemia-free survival (LFS) and relapse rate (RR) , and the potential prognostic factors well analyzed. The results showed that the 3 year OS , LFS and RR were 61.9%, 52% and 39.1% respectively. Univarite analysis demonstrated that the disease status before transplantation (P < 0.01) , donor type (P < 0.01), white blood cell count at initial diagnosis (P < 0.05) are related with outcome, and severe aGVHD has some influence on the outcome (P > 0.05) . Multivariate analysis indicated the status of disease before transplantation, donor type, severe aGVHD are the most important prognostic factors. It is concluded that the related PBHSCT is effective treatment method for AML patients, recurrence is the main reason for the failure after transplantation, disease status before transplantation, donor type, and severe aGVHD are independent prognostic factors.
