An analysis of more than 8000 patients provides insights regarding HLA disparity that may help optimize outcomes in individuals undergoing unrelated-donor hematopoietic stem cell transplant. The study showed that a single allele- or antigen-level HLA mismatch (7/8) increased the risk for acute and chronic... [Read Article]

Adding specialized T cells to allogeneic bone marrow transplants can prevent graft-vs-host disease (GVHD) while preserving the graft-vs-tumor (GVT) effect, preclinical research suggests. Donor-derived CD4+ invariant natural killer T cells (iNKT cells) helped protect mice from developing GVHD and lymphoma, thereby improving their survival.... [Read Article]

The order in which patients receive cyclophosphamide (Cy) and total body irradiation (TBI) does not affect the outcome of hematopoietic stem cell transplant (HSCT), researchers have reported. In a large, retrospective study, the rates of relapse, survival, chronic graft-vs-host disease (GVHD), and other complications were similar whether patients received... [Read Article]

Administering radioimmunotherapy (RIT) prior to non-myeloablative allogeneic transplant (NMAT) can improve survival in patients with persistent disease, according to a speaker at the 2014 BMT Tandem Meetings. Ryan Cassaday, MD, of the University of Washington in Seattle, noted that RIT-augmented NMAT can produce long-term... [Read Article]

Acute leukemia patients who undergo cord blood (CB) transplant have longer hospital stays than patients who receive other types of transplant, new research indicates. The study also suggests the length of stay (LOS) is similar whether patients receive double or single CB grafts. So it seems strategies are needed... [Read Article]

Results of a large, retrospective study suggest that allogeneic stem cell transplant (allo-SCT) can overcome the poor prognosis associated with central nervous system (CNS) involvement in acute myeloid leukemia (AML). By analyzing transplant outcomes in more than 5000 patients, researchers found that subjects with CNS AML had rates... [Read Article]

Intestinal bacteria can offer protection from death related to graft-vs-host disease (GVHD), according to research presented at the 2014 BMT Tandem Meetings. Experiments showed that Blautia, commensal bacteria found in the intestinal tract, can protect against GVHD-related mortality in mice and in humans. ... [Read Article]

The total nucleated cell (TNC) dose delivered in an allogeneic peripheral blood stem cell transplant (allo-PBSCT) can affect outcomes in certain patients, according to a study presented at the 2014 BMT Tandem Meetings. Researchers found that a higher TNC dose was associated with better progression-free survival (PFS) and overall survival (OS) among patients... [Read Article]
