Predictive factors for outcomes after reduced intensity conditioning hematopoietic stem cell transplantation for hematological malignancies: a 10-year retrospective analysis from the Société Française de Greffe de Moelle et de Thérapie Cellulaire.

This retrospective study analyzed the impact of demographic and transplantation variables on outcomes of 1108 patients who have undergone allogeneic hematopoietic stem cell transplantation after reduced intensity conditioning (RIC HSCT) for hematological malignancies and were reported to the Société Française de Greffe de Moelle et de Thérapie Cellulaire registry between November 1994 and December 2004. Only 442 patients (40%) were in complete remission (CR) at time of transplantation. Peripheral blood stem cells were used in the majority of patients (n = 878; 79%), 255 patients received fludarabine and low-dose total body irradiation, while 465 patients (42%) fludarabine and busulfan with rabbit anti-thymocyte globulins (ATG).

HLA Association with hematopoietic stem cell transplantation outcome: the number of mismatches at HLA-A, -B, -C, -DRB1, or -DQB1 is strongly associated with overall survival.

HLA matching between the donor and recipient improves the success of unrelated hematopoietic stem cell transplantation (HSCT). Because many patients in need of an unrelated transplant have only donors with mismatch, information is needed to evaluate the limits of HLA mismatching. We examined the association of survival, acute graft-versus-host disease (aGVHD) and relapse with HLA-A, -B, -C, -DRB, -DQB1, and -DPB1 mismatching in 334 patients coming from 12 French transplant centers and who received a non-T cell-depleted bone marrow graft from an unrelated donor.

Unrelated stem cell transplantation for severe acquired aplastic anemia: improved outcome in the era of high-resolution HLA matching between donor and recipient.

Background And Objectives: Severe acquired aplastic anemia (SAA) is a potentially fatal bone marrow failure syndrome occurring mainly in children and young adults. Immunosuppressive regimens and hematopoietic stem cell transplantation (HSCT) are the only two available curative treatments. Patients who lack an HLA-identical sibling donor may receive HSCT from an unrelated donor, a strategy historically associated with high mortality rates.

Allogeneic marrow stem-cell transplantation from human leukocyte antigen-identical siblings versus human leukocyte antigen-allelic-matched unrelated donors (10/10) in patients with standard-risk hematologic malignancy: a prospective study from the French Society of Bone Marrow Transplantation and Cell Therapy.

Purpose: To investigate the influence of donor type (human leukocyte antigen [HLA] -identical sibling donor versus HLA-A-, HLA-B-, HLA-Cw-, HLA-DRB1-, and HLA-DQB1-identical unrelated donors, or so-called 10/10) on the outcome of patients who underwent allogeneic stem-cell transplantation (alloSCT), adjusting for other prognostic factors, in patients with standard-risk hematologic malignancy.

Patients And Methods: Between March 2000 and January 2003, we prospectively investigated the outcome of 236 consecutive patients with standard-risk malignancy from 12 French centers. Fifty-five patients underwent alloSCT from an unrelated HLA-identical donor at the allelic level, whereas 181 patients received an alloSCT from an HLA-identical sibling.
