Conventional cytogenetics is invariably one of the most important methods used in diagnostics of chronic lymphoproliferations. It complements fluorescence in situ hybridization (FISH) and molecular analysis. Presence of particular chromosomal alterations in chronic lymphocytic leukemia enables patients' stratification into appropriate cytogenetic risk groups and influences treatment decisions. In other non-Hodgkin lymphomas cytogenetic analyses are employed also in minimal residual disease assessment.As lymphocytes in chronic lymphoid malignancies are characterized by low proliferation rate in vitro, it is critical to induce their division in the culture properly...

Gaucher disease (GD) patients have an increased risk of cancer, in particular of hematological origin, while the association between GD and Neuroblastoma (NBL) has never been described. Here we report the case of an adolescent diagnosed with NBL, also presenting splenomegaly and persistent thrombocytopenia. The association with GD, suggested by the histological findings on bone marrow biopsy, was confirmed by enzymatic and genetic tests. The possible pathogenetic mechanisms are briefly reviewed. The evidence of this new association supports the necessity of further studies on GD comorbidities and the need of systematic data collection and analysis, potentially through an international registry...

BACKGROUND: Non-Hodgkin lymphomas (NHL) are the most frequent hemato-oncological malignancies. Despite recent major advances in treatment, a substantial proportion of patients relapses highlighting the need for new therapeutic modalities. Promissory results obtained in pre-clinical studies are usually not translated when moving into clinical trials. Pre-clinical studies are mainly conducted in animals with high tumor burden; instead patients undergo chemotherapy as first line of treatment and most likely are under remission when immunotherapies are applied...

The role of radial-endobronchial ultrasound (R-EBUS) assisted transbronchial biopsy (TBB) for the diagnosis of peripheral pulmonary lesions is well established. However, no study has addressed its safety and value in hemato-oncological patients presenting with non-resolving infiltrates during persistent febrile neutropenia. To assess safety and feasibility of R-EBUS assisted TBB in severe thrombocytopenic and neutropenic patients. Over a period of 18 months, eight patients were assessed with R-EBUS assisted TBB after adequate platelet transfusion...

In order to improve the reporting of adverse drug reactions (ADRs) as part of the routine practice at the pediatric outpatient department (OPD), we modified our ADR reporting strategy into one that facilitates the reporting process by means of a multi-disciplinary approach. In this study, we retrospectively reviewed ADR records during the period from March to September 2014 when we changed our reporting process as a part of institutional quality assurance (QA) activity. Yearly differences in the number and composition of ADRs were compared, and the descriptive analyses were done for cases reported from OPD during the QA activity in terms of the suspected drugs, type, causality, and severity of ADRs...

Red cell alloimmunization may induce severe hemolytic side effects. Identification of risk modifying conditions will help tailor preventative strategies. This study aims to quantify the associations of hematological malignancies and solid cancers with red cell alloimmunization in patients receiving red cell transfusions. We performed a nested multicenter case-control study in a source population of 24,063 patients receiving their first and subsequent red cell transfusions during an eight year follow-up period...

UNLABELLED: Granulocyte transfusions for neutropenic patients have been used for over 40 years, although effectiveness, indications, and both patient and donor safety remain debated. This single-center study assessed the side effects, clinical course, and survival of granulocyte transfusions in critically ill pediatric patients, with underlying hemato-oncological disorders, prolonged neutropenia, and proven or suspected severe infection. Donor-specific side effects and influence of donor-specific characteristics on patient outcome were also investigated...

The use of a positive-displacement needleless intravenous access device was associated with lower microbial contamination rates compared with a neutral-displacement device when used on central venous catheters in hemato-oncology patients. In addition, rates of central line-associated bloodstream infection did not differ when either device was used.

Evidence on risk factors for Clostridium difficile infection (CDI) in hemato-oncologic patients is conflicting. We studied risk factors for CDI in a large, well-characterized cohort of hemato-oncological patients. 144 hemato-oncological patients were identified in this retrospective, single center study with a microbiologically confirmed CDI-associated diarrhea. Patients were compared with 144 age and sex matched hemato-oncologic patients with CDI negative diarrhea. Risk factors such as prior antimicrobial therapy, type of disease, chemotherapy and survival were evaluated...

OBJECTIVES: The ß-D-glucan assay (BDG) has been added to the EORTC/MSG criteria for the diagnosis of invasive fungal infections (IFI), but data from pediatric populations is scarce. The aim of this study was to evaluate performance of BDG in a cohort of hemato-oncological children with hematological malignancy at risk for IFI. METHODS: 113 patients were included through an 18-month period. In addition to routine IFI screening, BDG was assayed once a week. IFIs were classified using EORTC/MSG criteria without including the BDG results...

Multiple myeloma (MM) is a common hematological malignancy that has widespread manifestations in multiple organs, including bones and joints. This retrospective study aimed to evaluate the involvement of the temporomandibular joint (TMJ) in patients with MM. Consecutive subjects with a diagnosis of MM who presented to the oral and maxillofacial surgery clinic for routine evaluation between 2008 and 2014 were identified. Patients who had a computed tomography (CT) scan of the TMJs as part of their MM staging were included in the study...

CLINICAL/METHODICAL ISSUE: Biomedical imaging procedures play a major role in hemato-oncological diseases with respect to pre-therapeutic staging and assessment of treatment response. STANDARD RADIOLOGICAL METHODS: Originally, the therapeutic management was the domain of computed tomography (CT) and whole-body magnetic resonance imaging (MRI). METHODICAL INNOVATIONS: Over the last decade these purely morphological techniques have gradually been replaced by hybrid imaging techniques, such as positron emission tomography-CT (PET/CT) and PET/MRI, which also provide metabolic and functional information...

BACKGROUND: Multi-Arm Multi-Stage designs aim at comparing several new treatments to a common reference, in order to select or drop any treatment arm to move forward when such evidence already exists based on interim analyses. We redesigned a Bayesian adaptive design initially proposed for dose-finding, focusing our interest in the comparison of multiple experimental drugs to a control on a binary criterion measure. METHODS: We redesigned a phase II clinical trial that randomly allocates patients across three (one control and two experimental) treatment arms to assess dropping decision rules...

Chronic IS is associated with significant morbidity in transplant recipients. Moreover, IS does not prevent chronic graft failure frequently. Allograft immune tolerance in LT can be induced by complete donor chimerism through allogenic HSCT combined with identical LDLT. This approach may exempt patients from chronic lifelong IS. However, it is unclear whether its benefits justify its risks. Here, we present three cases from our institution and analyze seven additional reports of children treated with HSCT/LDLT, all receiving HSCT due to hemato-oncological indications...
