Pre- and post-transplantation factors associated with primary graft failure and severe poor graft function after allogeneic hematopoietic stem cell transplantation for chronic myeloid leukemia

Summary Allogeneic stem cell transplantation (allo-HSCT) is used worldwide for long-term management and cure of hematological malignancies, still remaining a valuable option for treatment of chronic myeloid leukemia (CML) in all fit patients who are unable to achieve a durable complete cytogenetic response after treatment with tyrosine kinase inhibitors (TKIs), and in advanced-phase disease. Along with relapse risk, the unfavorable HSCT results may be associated with primary graft failure (PrGF), or poor graft function (PoGF). Hence, the aim of our study was to assess frequency and outcome of PrGF and severe poor graft function (sPGF) after allo-HSCT in CML patients.
