Allogeneic hematopoietic SCT is well established as a potentially curative therapy for children and adults with both malignant and nonmalignant diseases. However, myeloablative SCT is associated with significant short- and long-term complications. The goals of a reduced intensity-conditioning (RIC) regimen are to prevent graft rejection and establish stable(More)
Although transplant practices have changed over the last decades, no information is available on trends in incidence and outcome of chronic graft-versus-host disease (cGVHD) over time. This study used the central database of the Center for International Blood and Marrow Transplant Research (CIBMTR) to describe time trends for cGVHD incidence, nonrelapse(More)
Autologous hematopoietic cell transplantation (AutoHCT) is a potentially curative treatment modality for relapsed/refractory Hodgkin lymphoma (HL). However, no large studies have evaluated pretransplant factors predictive of outcomes of AutoHCT in children, adolescents and young adults (CAYA, age <30 years). In a retrospective study, we analyzed 606 CAYA(More)
Acute graft-versus-host disease (aGVHD) still remains a major limiting factor following allogeneic stem cell transplantation (AlloSCT) in pediatric recipients. Mycophenolate mofetil (MMF), an uncompetitive selective inhibitor of inosine monophosphate dehydrogenase, is a new immunosuppressant agent without major mucosal, hepatic, or renal toxicity compared(More)
There have been no studies on patient outcome after allogeneic hematopoietic cell transplantation (HCT) in patients with X-linked inhibitor of apoptosis (XIAP) deficiency. To estimate the success of HCT, we conducted an international survey of transplantation outcomes. Data were reported for 19 patients. Seven patients received busulfan-containing(More)
BU and CY (BU/CY; 200 mg/kg) before HLA-matched sibling allo-SCT in children with sickle cell disease (SCD) is associated with ~85% EFS but is limited by the acute and late effects of BU/CY myeloablative conditioning. Alternatives include reduced toxicity but more immunosuppressive conditioning. We investigated in a prospective single institutional study,(More)
The prognosis for childhood acute lymphoblastic leukemia (ALL) has improved dramatically over the past quarter of a century. Despite improvements in the treatment of childhood ALL, relapse still occurs in 20%-30% of patients. Although many of these relapses occur in the "standard-risk" patients, approximately 10% of these patients present at diagnosis with(More)
OBJECTIVE The genetic and immunological mechanism(s) responsible for the significant decrease in the incidence of graft-vs-host disease (GVHD) following HLA-disparate unrelated cord blood transplantation remains largely unknown. In this study, we investigated if cord blood (CB) CD4(+)CD25(+) T cells play a significant role in reducing the immune responses(More)
The outcome of children, adolescents and young adults (CAYA) with poor-risk recurrent/refractory lymphoma is dismal (⩽30%). To overcome this poor prognosis, we designed an approach to maximize an allogeneic graft vs lymphoma effect in the setting of low disease burden. We conducted a multi-center prospective study of myeloablative conditioning (MAC) and(More)
CD34-selected haploidentical and unrelated donor allogeneic stem cell transplantation (AlloSCT) in paediatric recipients is associated with sustained engraftment and low risk of acute graft-versus-host disease (aGVHD), but limited by delayed immune reconstitution and increased risk of viral and fungal infection. The optimal dose of donor T cells to prevent(More)
