OBJECTIVE: Human herpesvirus 8 (HHV-8) is the causative agent of Kaposi's sarcoma (KS), but it has also been associated with different hematologic malignancies, including plasmablastic lymphoma, Multicentric Castleman's disease (MCD), primary effusion lymphoma (PEL) and various atypical lymphoproliferative disorders. Patients with underlying lymphoproliferative diseases and chronic blood disorders who become infected with this virus are at risk for human malignancies. This small study reported the frequency of human herpesvirus -8 in 81 Iranian patients with lymphoproliferative disorders for estimation of possible factors affecting malignancy...

BACKGROUND: The combined use of genetic markers and detectable minimal residual disease identifies patients with chronic lymphocytic leukaemia with poor outcome after first-line chemoimmunotherapy. We aimed to assess lenalidomide maintenance therapy in these high-risk patients. METHODS: In this randomised, double-blind, phase 3 study (CLLM1; CLL Maintenance 1 of the German CLL Study Group), patients older than 18 years and diagnosed with immunophenotypically confirmed chronic lymphocytic leukaemia with active disease, who responded to chemoimmunotherapy 2-5 months after completion of first-line therapy and who were assessed as having a high risk for an early progression with at least a partial response after four or more cycles of first-line chemoimmunotherapy, were eligible if they had high minimal residual disease levels or intermediate levels combined with an unmutated IGHV gene status or TP53 alterations...

The aim of this study was to investigate the relationship between pain, fatigue, sleep disorders and quality of life and assess the most powerful predictor of quality of life in patients with acute leukaemia. In this cross-sectional multicentre study, 406 patients were recruited. Data were collected using the Iranian Short-Form 36-item Health Survey, the Pittsburgh Sleep Quality Index, and the Numeric Rating Scale for Pain and Fatigue Intensity. It was found that pain and fatigue had direct relationship with sleep disorders...

Inv(16)(p13q22) and t(16;16)(p13;q22) are cytogenetic hallmarks of acute myelomonoblastic leukaemia, most of them associated with abnormal bone marrow eosinophils [acute myeloid leukaemia French-American-British classification M4 with eosinophilia (FAB AML-M4Eo)] and a relatively favourable clinical course. They generate a 5'CBFB-3'MYH11 fusion gene. However, in a few cases, although RT-PCR identified a CBFB-MYH11 transcript, normal karyotype and/or fluorescent in situ hybridization (FISH) analyses using commercially available probes are found...

BACKGROUND: Efficacy and the risk of severe late effects have to be well-balanced in treatment of Hodgkin lymphoma (HL). Late adverse effects include secondary malignancies which often have a poor prognosis. To synthesise evidence on the risk of secondary malignancies after current treatment approaches comprising chemotherapy and/or radiotherapy, we performed a meta-analysis based on individual patient data (IPD) from patients treated for newly diagnosed HL. OBJECTIVES: We investigated several questions concerning possible changes in the risk of secondary malignancies when modifying chemotherapy or radiotherapy (omission of radiotherapy, reduction of the radiation field, reduction of the radiation dose, use of fewer chemotherapy cycles, intensification of chemotherapy)...

PURPOSE: Corticoid-induced osteonecrosis (ON) of femoral head can lead to severe hip joint impairment and hip replacement, with negative impact in young survivors of acute lymphoblastic leukaemia (ALL) with long life expectancy. We aim to improve quality of life in these patients with a novel approach. METHODS/PATIENTS: Based on the regenerative capacities of mesenchymal stem cells (MSCs), we performed locally implanted autologous cell therapy in two adolescents suffering of bilateral femoral ON...

BACKGROUND: Although aberrant expression of cytokines and small molecules (analytes) is well documented in acute myeloid leukaemia (AML), their co-expression patterns are not yet identified. In addition, plasma baselines for some analytes that are biomarkers for other cancers have not been previously reported in AML. METHODS: We used multiplex array technology to simultaneously detect and quantify 32 plasma analyte (22 reported analytes and 10 novel analytes) levels in 38 patients...

Growth Factor Independence 1 (GFI1) is a transcriptional repressor that plays a critical role during both myeloid and lymphoid haematopoietic lineage commitment. Several studies have demonstrated the involvement of GFI1 in haematological malignancies and have suggested that low expression of GFI1 is a negative indicator of disease progression for both myelodysplastic syndromes (MDS) and acute myeloid leukaemia (AML). In this study, we have stratified AML patients into those defined as having a normal karyotype (CN-AML)...

Myeloid sarcoma is an extramedullary manifestation of Acute Myeloid Leukaemia and sometimes is the only indicator of the disease. The incidence varies between 3-9.1% of acute leukaemia cases. The blast infiltration is seen most commonly in skin, lymph node, gastrointestinal tract, bone, soft tissue though can involve any body site usually as a solitary lesion and is rarely seen in nasal cavity. We present two cases of myeloid sarcoma presenting as a nasal mass in a six year old girl and other as orbital mass in 32-year-old as an initial manifestation of acute myeloid leukaemia...

Inhibition of lysine specific demethylase 1 (LSD1) has been shown to induce the differentiation of leukemia stem cells in acute myeloid leukaemia (AML). Irreversible inhibitors developed from the non-specific inhibitor tranylcypromine have entered clinical trials; however, the development of effective reversible inhibitors has proved more challenging. Herein, we describe our efforts to identify reversible inhibitors of LSD1 from a high throughput screen, and subsequent in silico modelling approaches. From a single hit (12) validated by biochemical and biophysical assays, we describe our efforts to develop acyclic scaffold-hops from GSK-690 (1)...

BACKGROUND: Multiple Myeloma (MM) is currently incurable despite many novel therapies. Tumour Necrosis Factor-Related Apoptosis-Inducing Ligand (TRAIL) is a potential anti-tumour agent although effects as a single agent are limited. In this study, we investigated whether the Histone Deacetylase (HDAC) inhibitor SAHA can enhance TRAIL-induced apoptosis and target TRAIL resistance in both suspension culture, and 3D cell culture as a model of disseminated MM lesions that form in bone. METHODS: The effects of SAHA and/or TRAIL in 6 Multiple Myeloma cell lines were assessed in both suspension cultures and in an Alginate-based 3D cell culture model...

Acute lymphoblastic leukaemia (ALL) is the most common type of cancer in children, accounting for approximately 25% of childhood cancer cases. As a result of effective treatments over the past decades, paediatric ALL mortality has been greatly reduced. Chemotherapy, however, has a range of harmful side effects including the loss of protective antibodies against vaccine-preventable diseases. Since ALL survivors have an increased risk of health problems including organ insufficiencies, acquired vaccine-preventable infections subsequent to clinical remission could become life threatening to these individuals...

OBJECTIVES: To present a CUSUM plot based on Bayesian diagnostic reasoning displaying evidence in favour of "healthy" rather than "sick" quality of treatment (QOT), and to demonstrate a technique using Kaplan-Meier survival curves permitting application to case series with ongoing follow-up. METHODS: For a case series with known final outcomes: Consider each case a diagnostic test of good versus poor QOT (expected vs. increased failure rates), determine the likelihood ratio (LR) of the observed outcome, convert LR to weight taking log to base 2, and add up weights sequentially in a plot showing how many times odds in favour of good QOT have been doubled...

BACKGROUND: Myelodysplastic syndromes with chromosome 5 long arm deletion (5q-mds) may benefit from lenalidomide treatment. However, unresponsive patients have a high risk for clonal evolution and progression to acute myeloid leukemia. Case: We describe a 5q-patient treated with lenalidomide, who concomitantly developed acute myeloid leukemia and blastic plasmacytoid dendritic cell neoplasm, a rare and highly aggressive lymphoma. CONCLUSIONS: Evolution of 5q- syndrome to acute myeloid leukemia and blastic plasmacytoid dendritic cell neoplasm may have occurred through various mechanisms, including persistence of neoplastic lenalidomide-resistant stem cells and selection of a more aggressive clone via lenalidomide augmentation of the ARPC1B gene, or because of lenalidomide stimulation on dendritic cells...

Natural killer (NK) cell lymphoblastic leukaemia/lymphoma is a rare haemopoietic tumour currently defined in the 2008 WHO classification under the category of acute leukaemias of ambiguous lineage. A diagnosis of this type of leukaemia is considered in cases expressing CD56 along with immature T-cell-associated markers such as CD2 and CD7 with absence of B-cell and myeloid markers; in addition, blastic plasmacytoid dendritic cell leukaemia should be excluded. Prior to 2008, these precursor NK cell lymphoblastic leukaemias/lymphomas were categorized as myeloid/NK cell acute leukaemia with a phenotype identical to acute myeloid leukaemia with minimal differentiation...

Acute myeloid leukaemia (AML) often presents with non-specific symptoms such as fatigue, anaemia or infection. Pulmonary involvement is uncommon in AML during the course of the disease and is usually caused by infection, haemorrhage, leukaemic pulmonary infiltrates and leukostasis. Lung localization of AML is very uncommon and potentially life threatening if not diagnosed and treated rapidly. The authors describe the sudden death of an asymptomatic five-month-infant because of a misdiagnosed lung localization of AML...

REVIEW
Maria-Cristina Keightley, Graham J Lieschke
Splicing is a ubiquitous process in eukaryotic cells, long recognised as contributing to diversity of the transcriptome. More specifically, splicing fine-tunes the transcriptome output for highly individual outcomes at different stages of cell development, in specific timeframes, which when perturbed result in significant human diseases. Granulopoiesis provides a particularly well studied example of how splicing can be a highly flexible but tightly regulated process. Focusing on the specific case of granulopoiesis, this review surveys the contribution of cis-splicing variations in individual genes and the trans-regulation of global splicing outcomes during the normal development of neutrophils...
