The tyrosine kinase inhibitor (TKI) imatinib has been used for a decade to treat chronic myeloid leukemia (CML). A very efficient response is obtained with patients in chronic phase, but its efficacy in late phase patients is often transient. The combination of imatinib or of the new TKI nilotinib with cytarabine is a new treatment approach proposed for CML. We have investigated the effect of i...
Previous studies demonstrated that ataxia telangiectasia mutated- and Rad3-related (ATR) kinase and its downstream target checkpoint kinase 1 (Chk1) facilitate survival of cells treated with nucleoside analogs and other replication inhibitors. Recent results also demonstrated that Chk1 is depleted when cells are treated with heat shock protein 90 (Hsp90) inhibitor 17-allylamino-17-demethoxygeld...
We report on 2 patients who developed widespread cerebral vasospasm and arterial ischemic strokes (AIS) after application of intrathecal (IT) cytarabine. In a 3-year-old child with acute lymphoblastic leukemia (ALL), left leg weakness, hyperreflexia, and clonus were noted 4 days after her first dose of IT cytarabine during the induction phase of her chemotherapy. Cerebral MRI revealed multiple ...
A whole-genome approach was used to investigate the genetic determinants of cytarabine-induced cytotoxicity. We performed a meta-analysis of genome-wide association studies involving 523 lymphoblastoid cell lines (LCLs) from individuals of European, African, Asian, and African American ancestry. Several of the highest-ranked single-nucleotide polymorphisms (SNPs) were within the mutated in colo...
Allogeneic bone marrow transplantation is an effective postremission strategy for patients with acute myelogenous leukemia (AML) in first complete remission (CR). The value of administering consolidation chemotherapy before human leukocyte antigen (HLA)-identical sibling transplantation is not established. Outcomes of patients with AML in first CR receiving no consolidation therapy, standard-do...
Etoposide and cytarabine have been shown to exert high antileukemic activity and are currently under study as preparatory agents before allogeneic bone marrow transplantation. However, data concerning their engraftment-promoting potency are scarce. Therefore, we tested these agents in LEW rats receiving a myeloablative dose of busulfan followed by transfer of F1 (CAP X LEW) marrow, which is una...
BACKGROUND High-dose cytarabine has been associated with a high frequency of viridans group streptococcal (VGS) bacteraemia. VGS bacteraemia causes considerable morbidity and mortality. The Nordic Society of Paediatric Haematology and Oncology (NOPHO)-AML protocols use higher cumulated doses of cytarabine and more chemotherapy series (n = 6) than other protocols with the potential increased ris...
The transcription factor interferon regulatory factor-8 (IRF8) is highly expressed in myeloid progenitors, while most myeloid leukemias show low or absent expression. Loss of IRF8 in mice leads to a myeloproliferative disorder, indicating a tumor-suppressive role of IRF8. The Wilms tumor gene 1 (WT1) protein represses the IRF8-promoter. The zinc finger protein ZNF224 can act as a transcriptiona...
Acute myeloid leukemia (AML) remains a challenging disease to treat and urgently requires new therapies to improve its treatment outcome. In this study, we investigated the molecular mechanisms underlying the cooperative antileukemic activities of panobinostat and cytarabine or daunorubicin (DNR) in AML cell lines and diagnostic blast samples in vitro and in vivo. Panobinostat suppressed expres...
each, although toxicities were not directly attributed to the agent.2 In their letter, Chamberlain and Glantz comment on the neurologic syndromes we reported and question attribution to liposomal cytarabine. Our attributions were based on 15-year experience in nearly 500 adults with acute lymphoblastic leukemia without central nervous system (CNS) disease, treated with hyperCVAD (cyclophosphami...
