BackgroundIndia in bone marrow donation and transplantation, particularly in the context of increasing incidence of haematological neoplasms like acute myeloid leukaemia (AML). The use of matched related donors (MRD) for hematopoietic stem cell transplantation (HSCT) is a feasible option, but the lack of HLA-matched donors in India remains a significant obstacle to successful treatment Methodology- This retrospective study was conducted at the Department of Hemato-Oncology & Bone Marrow Transplant, Rajiv Gandhi Cancer Institute in New Delhi, India over a period of 6 months. The study enrolled 77 acute myeloid leukemia (AML) MRD and 19 AML MUD patients based on the inclusion and exclusion criteria. ResultThe one-year survival rate was higher in MRD than in MUD, but there was no significant difference in mortality in multivariate analysis. The study also found that chronic graft-versus-host disease (GVHD) and relapse were associated with worse survival outcomes in both MRD and MUD HSCT. ConclusionThis study supports the use of matched unrelated donor (MUD) transplant for hematopoietic stem cell transplantation (HSCT) in acute myeloid leukemia (AML) patients when a matched sibling donor is not available.
