The insufficient standardisation of diagnostic next-generation sequencing (NGS) still limits its implementation in clinical practice, with the correct detection mutations at low variant allele frequencies (VAF) facing particular challenges. We address here coverage depth order to minimise probability false positive and negative results, latter being underestimated NGS. There is currently no consensus on minimum depth, so each laboratory has set own parameters. To assist laboratories...

Chronic lymphocytic leukaemia (CLL) has one of the strongest familial risks all cancers, as evidenced by eight-fold increased risk seen in relatives CLL patients, yet much heritable remains unexplained [1]. Patients with also have a high rate secondary cancer, i.e., development second primary malignancy, compared to general population, which may be explained immune dysregulation due and/or its treatment, but environmental and genetic factors [2]. The cancer patients contributes higher...

The significance of positron emission tomography/computed tomography (PET/CT) in chronic lymphocytic leukemia (CLL) has not yet been systematically studied. This prospective study was aimed at assessing the benefit PET/CT patients with newly diagnosed or relapsed CLL and Richter transformation (RT). examination performed 23 disease, 13 disease eight suspected histopathologically confirmed RT.

Abstract Extramedullary disease (EMM) represents a rare, aggressive and mostly resistant phenotype of multiple myeloma (MM). EMM is frequently associated with high-risk cytogenetics, but their complex genomic architecture largely unexplored. We used whole-genome optical mapping (Saphyr, Bionano Genomics) to analyse the CD138+ cells isolated from bone-marrow aspirates an unselected cohort newly diagnosed patients (n = 4) intramedullary MM 7). Large intrachromosomal rearrangements (> 5 Mbp)...

A growing body of studies highlights involvement neutrophils in cancer development and progression. Our aim was to assess the phenotypic functional properties circulating from patients with chronic lymphocytic leukemia (CLL). The percentage CD54+ CD64+ as well CD54 expression on these cells were higher CLL than age-matched healthy controls. Neutrophils produced more reactive oxygen species (ROS) compared controls both resting activated conditions. Lipopolysaccharide-induced production IL-1β...

Positron emission tomography using 2-[fluorine-18]-fluoro-2-deoxy-D-glucose ((18) F-FDG) is considered to be the most beneficial imaging method for staging patients with non-Hodgkin's lymphoma (NHL). The intensity of (18) F-FDG accumulation may determined by calculating so-called standardised uptake value (SUV). study aimed at assessing benefit SUV(max) determination in PET/CT untreated NHL.One hundred and forty-nine initial scans performed NHL between January 2007 August 2009 were assessed,...

MicroRNAs (miRNAs) are small non-coding single-stranded RNA molecules that regulate gene expression at the post-transcriptional level. In pathogenesis of chronic lymphocytic leukemia (CLL), miR-15a and miR-16-1 play an important role. These miRNAs located on chromosome 13 in 13q14.3 region, which is deleted more than 55% CLL patients. This aberration affects miRNAs.The study aimed performing a molecular genetic analysis group 39 patients diagnosed with determining association between two...
