High lactate dehydrogenase at time of admission for allogeneic hematopoietic transplantation associates to poor survival in acute myeloid leukemia and non-Hodgkin lymphoma

Risk stratification is important for balancing potential risks and benefits of allogeneic hematopoietic stem cell transplantation (HSCT) for hematological malignancies. We retrospectively studied 1119 patients undergoing allogenic-HSCT in a single center for five hematological indications assessing the prognostic role of LDH at admission for survival (OS), progression-free survival (PFS), relapse incidence (RI), and nonrelapse mortality (NRM). In non-Hodgkin lymphoma (NHL) and acute myeloid leukemia (AML), higher than median LDH had an adverse effect on survival. The prognostic significance was strongest in AML, with higher LDH levels having lower 1-and 3-year survival 69.2% vs. 50.8%, P
