| Popis: | Introduction: Patients with benign or malignant blood disorders, who require allogeneic stem cell transplantation and lack an identical human leukocyte antigen HLA identicalHL sibling donor, could be transplanted with hematopoietic stem cells from unrelated adult or umbilical cord donors. However, in our country, both approaches are costly and time-consuming options. Methods: Over the last few years, haploidentical modalities have been investigated as an alternative donor source, showing similar results to those obtained with identical HLA donors. We started using T-cell-replete haploidentical with post-transplant cyclophosphamide in 2012 and we presented our experience with patients undergoing haploidentical ransplantation compared to SIB. Results: Since January 2012 to date, 91 allogeneic transplants have been performed, of which 49 were haploidentical and 42 were HLA identical. The mean age of the patients was 35 years (range: 17–62). The mean CD34/kg × 106 infused per group was 5.93 and 5.89, respectively. Time to granulocyte and platelet engraftment was 11 and 15 days, respectively, for haploidentical, and 12 and 14 days, respectively, for HLA identical (p = 0.10). The 100-day cumulative incidence of global acute GVHD was 34% for haploidentical and 29% for SIHLA identical (p = 0.9). The 2-year overall global graft-versus-host disease was 43% for haploidentical and 41% for HLA identical (p = 0.8). Overall survival, relapse, and transplant and relapse-related mortality were similar between both groups. Conclusion: Our experience showed that haploidentical has similar outcomes to those obtained with HLA idential and can be performed in our country safely.
