Outline of Final Research Achievements |
The pretransplant WT1 mRNA level was a powerful prognostic factor in allo-HCT for non-CR AML patients. High peak serum IL-6 level after HLA-haploidentical allogeneic hematopoietic cell transplantation with post-transplantation cyclophosphamide (PT/Cy-haplo) was identified a significant risk factor for very severe cytokine release syndrome (CRS) and poor 3-year overall survival. Counts of CD4+ T-cell subsets, CD8+ T-cell subsets, and NK cells were lower in PT/Cy-haplo than those in HLA-matched related HCT. The immune recovery pace in PT/Cy-haplo subsequently caught up with that of the other grafts. The regulatory T cells (Tregs) to conventional CD4+ T-cell (Tcon) ratio was significantly higher in PT/Cy-haplo. A higher Tregs-to-Tcon ratio was significantly associated with a lower incidence of chronic GVHD. A diagnostic approach using per-rectal portal scintigraphy for sinusoidal obstruction syndrome was useful.
