RBC transfusion requirements after allogeneic marrow transplantation: impact of the before‐transplant Hb level on transfusion and early survival

BACKGROUND : Most patients undergoing allogeneic marrow transplantation (alloBMT) require transfusions of RBCs. A retrospective analysis was performed to evaluate the utilization and risk factors for RBC transfusions including age and sex of recipient, HLA matching between donor and recipient, disease status at time of BMT, the occurrence of GVHD, ABO blood group compatibility, the source of progenitor cells and the Hb level before BMT (PT‐Hb).
