In this retrospective study of the Infectious Disease Working Party in collaboration with the Acute Leukemia Working Party the investigators analyzed the impact of  prior invasive fungal infection on outcome after allogeneic stem cell transplantation. They analyzed 1150 patients with acute leukemia and data on previous invasive fungal infection. Interestingly, the authors found no significant difference in NRM, Relapse and survival of patients with or without prior invasive fungal infection. In contrast to smaller studies, which suggested a negative impact of prior invasive fungal infection, the results of this very large cohort of patients suggested that patients with prior invasive fungal infection should not be excluded from allogeneic stem cell transplantation. Unfortunately, from the reported data in the registry it was not clear whether the prior fungal infection was resolved or still ongoing at time of transplant, therefore, the authors are now planning a prospective study.

Large granular lymphocyte (LGL) leukemia is a rare lymphoproliferative disorder characterized by clonal expansion of either CD3+ cytotoxic T-lymphocytes or CD3 NK cells.
A total of 33 patients fulfilling the inclusion criteria were identified in the EBMT registry (allo-HSCT 20 and auto-HSCT 13) but only in 15 patients, the requested additional data could be retrieved and the diagnosis of LGL finally confirmed in all (allo-HSCT 10, auto-HSCT 5). From 10 allogeneic transplanted patients, five patients are still alive and in remission after a median follow-up of 30 months, resulting into a 2-year PFS and OS of 50% each. From 5 autologous transplanted patients, two remain alive and disease-free 27 and 52 months post auto-HSCT, respectively. Despite the small number of patients included, the results provide first evidence of hematopoietic stem cell transplantation as a potential curative option in rare aggressive and relapsing forms of T-LGL leukemia

In a recent report of the Pediatric Disease Working Party encouraging results of treosulfan as conditioning regimen has been reported for non–malignant diseases. Here, the Pediatric  Disease Working Party reported the results of treosulfan as part of the conditioning regimen in children and adolescents with hematological malignancies. They included 193 children with ALL (n = 71), AML (n = 47), MDS/MPS ( n = 40) and other leukemia/lymphoma (n = 25)
Regimen-related toxicity was low and mainly gastrointestinal. There was no association of toxicity with type of disease or treosulfan dose. High-grade early toxicity was not higher in infants or patients undergoing second or later transplantation. Treatment related mortality was low at 14%. Three-year event-free survival was 45 ± 4% and not significantly influenced by number of transplants, however it appeared to be significantly better for infants (P = 0.022). When compared to treosulfan plus fludarabine, the combination of treosulfan, fludarabine and an alkylator (either thiotepa or melphalan) resulted in significantly better overall survival (OS, P = 0.048) and a trend toward better EFS.
This results confirmed the low toxicity profile and high anti-leukemic activity of treosulfan , especially if it is combned with another alkylating agent.
