Multicenter Study Clinical TrialProspective multicenter study of single-unit cord blood transplantation with myeloablative conditioning for adult patients with high-risk hematologic malignancies.
Although the use of cord blood transplantation (CBT) is increasing, the optimal methods for conditioning and graft-versus-host disease (GVHD) prophylaxis remain to be established. Among previous reports, the Institute of Medical Science, University of Tokyo (IMSUT) has reported remarkably favorable results of CBT for hematologic malignancies as a single-institute experience. The aim of the present multicenter prospective study was to assess the safety and efficacy of CBT performed precisely according to IMSUT transplantation procedures. ⋯ Causes of nonrelapse mortality were infection (n = 4) and graft failure (n = 1). The overall and disease-free survival rates were 51% (95% CI, 34%-68%) and 42% (95% CI, 26%-59%), respectively. These results suggest that the IMSUT CBT procedures can safely provide a high disease-free survival rate in patients with high-risk hematologic malignancies.

Feasibility of frequent patient-reported outcome surveillance in patients undergoing hematopoietic cell transplantation.
Patient-reported outcomes (PROs), including symptoms and health-related quality of life (HRQOL), provide a patient-centered description of hematopoietic cell transplantation (HCT)-related toxicity. These data characterize the patient experience after HCT and may have prognostic usefulness for long-term outcomes after HCT. We conducted a study of 32 patients after HCT (10 autologous HCT recipients, 11 full-intensity conditioning allogeneic HCT recipients, and 11 reduced-intensity conditioning allogeneic HCT recipients) to determine the feasibility of weekly electronic PRO collection from HCT until day (D) +100. ⋯ Median physical health HRQOL scores decreased with time in the 3 cohorts, and HRQOL was generally correlated with overall symptom severity. Our results demonstrate the feasibility of frequent electronic PROs in the early post-HCT period. Future studies in larger populations to explore predictive models using frequent PRO data for outcomes, including long-term HRQOL and survival, are warranted.

Treosulfan-thiotepa-fludarabine-based conditioning regimen for allogeneic transplantation in patients with thalassemia major: a single-center experience from north India.
Hematopoietic stem cell transplantation (HSCT) is the definite treatment for patients with thalassemia major. A busulfan (Bu) and cyclophosphamide (Cy)-based regimen has been the standard myeloablative chemotherapy, but it is associated with higher treatment-related toxicity, particularly in patients classified as high risk by the Pesaro criteria. Treosulfan-based conditioning regimens have been found to be equally effective and less toxic. ⋯ One patient had moderate veno-occlusive disease, 2 patients developed acute GVHD, 2 patients had chronic GVHD, and 2 patients experienced graft rejection. There was no TRM in this group. We found no significant differences between the 2 groups (treo/thio/flu vs Bu/Cy/ATG) in terms of the incidence of acute GVHD, chronic GVHD, TRM, and graft failure, although a trend toward higher TRM was seen with the treo/thio/flu regimen.
