ConclusionHigh-dose chemotherapy and autologous stem cell transplant using TBC conditioning for both PCNSL and secondary CNS non-Hodgkin lymphoma appears to have encouraging long term efficacy with manageable side effects.

We report a patient with a history of 2 occurrences of leukemia relapse due to mismatched HLA loss after haplo-SCT. He received haplo-SCT from his father but showed leukemia relapse with loss of the maternal HLA haplotype. He then underwent haplo-SCT from his mother, and developed relapse with loss of the paternal HLA haplotype. Both donors had killer cell immunoglobulin–like receptor-ligand mismatch but alloreactive natural killer cells could not prevent relapse. Second haplo-SCT should be conducted carefully for patients with relapse due to mismatched HLA loss.

We present a case of an infant with acute lymphoblastic leukemia undergoing hematopoietic stem cell transplantation. Before transplantation an unusual double colonization of the gastrointestinal tract with extremely resistant Escherichia coli and Klebsiella pneumoniae strains producing metallo-beta-lactamase was diagnosed. Respective epidemiologic management was implemented, based on the strict reverse isolation in patient-protective environment, and intensified antimicrobial surveillance. After granulocyte recovery, no extremely drug-resistant strains were found, and no case of isolation and/or transmission of carbapenem-...

Pediatric myelodysplastic syndromes (MDS) represent a spectrum of rare hematopoietic stem cell disorders characterized by cytopenias, ineffective hematopoiesis, marrow dysplasia and risk for leukemic transformation. While some cases are likely acquired due to de novo transformation, germline mutations in DNA repair pathways, ribosomal pathways, the telomere complex or in hematopoietic transcription factors (e.g., CEBPA, RUNX1, GATA2 and ETV6) are predisposition syndromes underlying many pediatric cases of MDS and acute myeloid leukemia (AML).

Allogeneic hematopoietic stem cell transplantation (allo HCT) is the only known potentially curative treatment for myelodysplastic syndromes (MDS) and chronic myelomonocytic leukemia (CMML). However, outcomes are generally poor, with a significant risk of relapse or transplant-related mortality. Prognosis for transplanted MDS patients can be delineated by widely used clinical scores such as the Revised International Scoring System (IPSS-R). Overall survival (OS) at 5 years post transplantation ranges from 23% to 71% for patients with very-high and very-low risk IPSS-R scores, respectively [1].

ConclusionT2B2F is associated with a higher incidence of acute GVHD compared with T1B2F. These results suggest that a lower dose-intensity of thiotepa and busulfan in the TBF regimen may yield better results in patients with AML in CR.

Authors: Gorshein E, Weber UM, Gore S Abstract Introduction: Myelodysplastic Syndrome (MDS) represents a group of cancers characterized by abnormal blood cell formation and maturation, leading to various degrees of cytopenias and potential transformation to acute myeloid leukemia. Deletion of the long arm of chromosome 5 (del(5q)) is the most common clonal chromosomal anomaly in MDS, yet the population in this disease subtype is quite heterogeneous. This manuscript analyzes literature on high-risk MDS with del(5q) abnormalities.Areas covered: The paper will review outcomes with lenalidomide among high-risk MDS pati...
