The Hungarian Childhood Cancer Registry, a population-based national registry of the Hungarian Paediatric Haemato-Oncology Network founded in 1971, monitors the incidence and mortality of childhood cancer. Our aims were to carry out a longitudinal study to investigate the trends and spatial inequalities of incidence and survival of leukaemia, and the association between survival and deprivation in Hungary. All cases of childhood leukaemia and myelodysplasia were analysed (3157 cases, 1971-2015, age: 0-14 years)...

Cancer cells frequently possess extra amplified centrosomes clustered into two poles whose pseudo-bipolar spindles exhibit reduced fidelity of chromosome segregation and promote genetic instability. Inhibition of centrosome clustering triggers multipolar spindle formation and mitotic catastrophe, offering an attractive therapeutic approach to selectively kill cells with amplified centrosomes. However, mechanisms of centrosome clustering remain poorly understood. Here, we identify a new pathway that acts through NIMA-related kinase 6 (Nek6) and Hsp72 to promote centrosome clustering...

The genomic lesions that characterise acute lymphoblastic leukaemia in childhood include recurrent translocations that result in the expression of fusion proteins. These translocations typically involve the rearrangement of genes encoding tyrosine kinases, including receptor tyrosine kinase, cytokine receptors and transcription factors. These confer phenotypic changes that are the hallmarks of malignant transformation, including unrestricted proliferation and a relative resistance to apoptosis. In this review, we explore the molecular mechanisms that link these fusions to the control of cell death...

Multicolour Flow Cytometry (MFC) produces multidimensional analytical data on the quantitative expression of multiple markers on single cells. This data contains invaluable biomedical information on (1) the marker expressions per cell, (2) the variation in such expression across cells, (3) the variability of cell marker expression across samples that (4) may vary systematically between cells collected from donors and patients. Current conventional and even advanced data analysis methods for MFC data explore only a subset of these levels...

Acute lymphoblastic leukaemia (ALL) occurs in approximately 1:1500 children and is less frequently found in adults. The most common immunophenotype of ALL is the B cell lineage and within B cell precursor ALL, specific genetic aberrations define subtypes with distinct biological and clinical characteristics. With more advanced genetic analysis methods such as whole genome and transcriptome sequencing, novel genetic subtypes have recently been discovered. One novel class of genetic aberrations comprises tyrosine kinase-activating lesions, including translocations and rearrangements of tyrosine kinase and cytokine receptor genes...

Survival after acute paediatric (0-14 years), adolescent (15-19 years) and young adult (20-39 years) leukaemia has improved substantially over the last five decades, particularly for acute lymphoblastic leukaemia (ALL) and acute promyelocytic leukaemia. This progress represents one of the most successful achievements in the history of medicine and has been attributed to the development of effective chemotherapy regimens, improvement in supportive care, better risk stratification, use of targeted therapies, and advances in haematopoietic stem cell transplantation...

MLL-rearranged acute lymphoblastic leukaemia (ALL) represents an aggressive malignancy in infants (<1 year of age), associated with poor outcome. Current treatment intensification is not further possible, and novel therapy strategies are needed. Notably, MLL-rearranged ALL is characterised by a strongly deregulated epigenome and shows sensitivity to epigenetic perturbators. Here, we demonstrate the in vivo efficacy of the histone deacetylase inhibitor Panobinostat (LHB589) using xenograft mouse models of MLL-rearranged ALL...

Acute myelogenous leukaemia (AML) is a clonal process involving the myeloid subgroup of white blood cells. Chloromas, or myeloid sarcomas, are masses of myeloid leukaemic cells and are a unique aspect of AML. This case involves a 14-year-old boy with AML who presented with multiple chloromas at diagnosis. The patient's extra-calvarial masses and bone marrow involvement responded to chemotherapy; however, his sacral epidural chloromas persisted despite four courses of chemotherapy. The central nervous system, bone marrow and testes have been known to be sanctuary sites for AML...

BACKGROUND: The INO-VATE study demonstrated efficacy and safety of inotuzumab ozogamicin versus standard care in adults with relapsed or refractory B-cell acute lymphoblastic leukaemia. Here, we report the frequency of, and potential risk factors for, hepatotoxicity in patients in this trial and after treatment and subsequent haemopoietic stem-cell transplantation (HSCT). METHODS: In this open-label, phase 3, multicentre, international study, adults with relapsed or refractory, CD22-positive, Philadelphia chromosome (Ph)-positive or Ph-negative B-cell acute lymphoblastic leukaemia who were due to receive first or second salvage treatment were randomly assigned (1:1) via an interactive voice response system to receive inotuzumab ozogamicin (starting dose 1·8 mg/m(2) per cycle [0·8 mg/m(2) on day 1; 0·5 mg/m(2) on days 8 and 15 of a 21-28 day cycle for ≤6 cycles]) or standard care (either fludarabine plus cytarabine plus granulocyte colony-stimulating factor, mitoxantrone plus cytarabine, or high-dose cytarabine)...

Several studies have reported an impact of the adult haematopoietic stem cells donors cytomegalovirus (CMV) serostatus on allogeneic haematopoietic cell transplantation (HCT) outcomes. Limited data, however, are available on the impact of cord blood unit (CBU) CMV serostatus on allogeneic umbilical cord blood transplantation (UCBT) outcomes. We analysed, retrospectively, the impact of CBU CMV serostatus on relapse incidence (RI) and 2-year non-relapse mortality (NRM) of single-unit CBU transplantation for acute leukaemia...

The introduction of PD-1/PD-L1 pathway inhibitors is an important landmark in solid oncology with unprecedented practice-changing activity in various types of solid tumours. Amongst haematological malignancies, PD-1/PD-L1 inhibitors have been successful, so far, only in the treatment of classical Hodgkin lymphoma, which typically exhibits an over-expression of PD-1 ligands (PD-L1, PD-L2) due to alterations in chromosome 9p24.1. Such positive outcomes led to the FDA approval of nivolumab use in relapsed Hodgkin lymphoma in 2016 as the first haematological indication...

Smoking has been identified as a significant risk factor for acute myeloid leukaemia (AML). However, epidemiological evidence for the effect of smoking on the risk of AML among Asians is scarce. Here, we investigated the impact of smoking habits on the risk of AML by conducting a pooled analysis of 9 population-based prospective cohort studies in Japan. We analysed original data on smoking habits at baseline from 9 cohort studies. Hazard ratios (HRs) in the individual studies were calculated using a Cox proportional hazard model adjusted for potential confounders and combined using a random-effects model...

Alterations to the gene encoding the EZH2 (KMT6A) methyltransferase, including both gain-of-function and loss-of-function, have been linked to a variety of haematological malignancies and solid tumours, suggesting a complex, context-dependent role of this methyltransferase. The successful implementation of molecularly targeted therapies against EZH2 requires a greater understanding of the potential mechanisms by which EZH2 contributes to cancer. One aspect of this effort is the mapping of EZH2 partner proteins and cellular targets...

Targeted next generation sequencing platforms have been increasingly utilised for identification of novel mutations in myeloid neoplasms, such as acute myeloid leukaemia (AML), and hold great promise for use in routine clinical diagnostics. In this study, we evaluated the utility of an open source variant caller in detecting large indels in a targeted sequencing of AML samples. While we found that this bioinformatics pipeline has the potential to accurately capture large indels (>20 bp) in patient samples, we highlighted the pitfall of a confounding ZRSR1 pseudogene that led to an erroneous ZRSR2 variant call...

Acute myeloid leukaemia (AML) is a malignancy in need of new therapeutic options. The current standard of care chemotherapy, leads to complete remission (CR) in the vast majority of adult patients under the age of 60. In contrast, CR rates in patients over the age of 60 reaches only 40-60%. While achievement of a CR is an important stepping stone in the treatment of AML, the majority of these patients experience relapse and die of their disease without adequate consolidation chemotherapy. Blood and marrow transplantation (BMT) can improve outcome in a select patient with AML but unfortunately, it is not a valid treatment option for the majority of older patients...
