Non-Inferior Survival of Black Versus White Patients and Superior Outcomes for Black Females Compared to Other Race/Gender Groups Following Allogeneic Transplantation for Hematologic Malignancy: A Single Center Multivariable Analysis of 475 Allografted Patients

The effect of race on outcomes following allogeneic hematopoietic cell transplantation (allo-HCT) is unclear. Earlier studies suggested no clear difference between black and white patients for conventional allografts (Baker et al JCO 2005, 23:7032) and inferior outcomes for black patients following single unit umbilical cord blood transplants(UCBT) (Ballen et al BBMT 2012, 18:903). The advent of HLA-haploidentical donor transplantation using T-replete grafts and post-transplant cyclophosphamide (HIDT-ptCy) has improved donor availability for black patients. However, the effect of race on allograft outcomes in the era of HIDT-ptCy has not been reported. We compared outcomes by race in 475 consecutive patients (white=383, black=83, Asian =9) undergoing a first allograft for hematologic malignancy at our center between February 2005 and February 2014. Hispanic/latino was classified as an ethnicity separate from race and was not exclusive of race categories. Patients with Disclosures No relevant conflicts of interest to declare.
