Article Synopsis
  • The t(14;19)(q32;q13) chromosomal rearrangement leads to the overexpression of the BCL3 gene through its juxtaposition with the immunoglobulin heavy chain (IGH) gene, affecting various lymphoid neoplasms.
  • An analysis of 13 lymphoid neoplasms with BCL3 rearrangement identified two distinct breakpoint clusters that result in different clinical outcomes: 5' breakpoints near an IGH enhancer causing overexpression of BCL3, and 3' breakpoints leading to no overexpression.
  • The study revealed that upstream BCL3-R tumors are related to atypical chronic lymphocytic leukemia while downstream BCL3-R tumors are linked to marginal zone lymphomas,

Article Synopsis
  • * A study in Spain involving 230 CLL cases and 1634 controls investigated whether the consumption of ultra-processed food and drinks (UPF) is linked to CLL, but found no overall association in the general population.
  • * However, for individuals diagnosed with CLL within the last year, a 10% increase in UPF consumption was associated with a 22% higher risk of CLL, indicating that further, more robust studies are needed to fully understand this relationship.

We aimed to study the association between occupational exposure to pesticides and chronic lymphocytic leukemia (CLL) in Spain. Occupational exposure to pesticides (four insecticides, four herbicides and two fungicides) was evaluated using a job-exposure matrix for the Spanish population (MatEmESp) among 302 CLL cases and 1567 population controls in five regions of Spain, 2010-2013. Cumulative exposure scores (CES) were obtained by summing across the exposed jobs the product of prevalence, intensity and duration of exposure to each active substance.

Chronic inflammation plays a role in the development of chronic lymphocytic leukaemia (CLL), and diet might modulate chronic inflammation. This study aims to evaluate the association between the dietary inflammatory index (DII) and CLL. A total of 366 CLL cases and 1643 controls of the Spanish multicase-control (MCC) Spain study were included.

Introduction: Preventable risk factors for chronic lymphocytic leukemia (CLL) remain largely unknown. The aim of this study was to evaluate the association between adherence to nutrition-based guidelines for cancer prevention and CLL, in the MCC-Spain case-control study.

Methods: A total of 318 CLL cases and 1293 population-based controls were included in the present study.

Diet is a modifiable risk factor for several neoplasms but evidence for chronic lymphocytic leukemia (CLL) is sparse. Previous studies examining the association between single-food items and CLL risk have yielded mixed results, while few studies have been conducted on overall diet, reporting inconclusive findings. This study aimed to evaluate the association between adherence to three dietary patterns and CLL in the multicase-control study (MCC-Spain) study.

Introduction: Chronic Lymphocytic Leukemia (CLL/SLL) is the most common adult leukemia in Western countries. Although it is mostly an indolent disease it is still incurable and with limited knowledge in relation to its etiology. We aim to confirm and quantify established risk factors for CLL/SLL using a multi-center epidemiological population-based case-control study on CLL/SLL as well as to explore new exposures inconclusively associated with CLL/SLL METHODS: Using the framework provided by the large MCC-Spain case-control study, we explored established and suggested risk factors associated with CLL/SLL using data collected through a face-to-face interview.

Fluorizoline is a new synthetic molecule that induces apoptosis by selectively targeting prohibitins. In the study herein, the pro-apoptotic effect of fluorizoline was assessed in 34 primary samples from patients with chronic lymphocytic leukemia. Fluorizoline induced apoptosis in chronic lymphocytic leukemia cells at concentrations in the low micromolar range.

CD34 positivity has been considered as an adverse prognostic factor in acute myeloid leukemia (AML). Although nucleophosmin 1-mutated (NPM1m) AML is usually CD34 negative, this marker may be expressed at diagnosis or acquired at relapse in a variable number of cases. Our objective was to ascertain if CD34 expression has any influence on the general outcome of this form of acute leukemia.

Chronic lymphocytic leukemia (CLL) has few known modifiable risk factors. Recently, circadian disruption has been proposed as a potential contributor to lymphoid neoplasms' etiology. Serum melatonin levels have been found to be significantly lower in CLL subjects compared with healthy controls, and also, CLL prognosis has been related to alterations in the circadian molecular signaling.

Acute myeloid leukemia (AML) with myelodysplasia-related changes is characterized by the presence of multilineage dysplasia (MLD), frequently related to high-risk cytogenetics and poor outcome. However, the presence of MLD does not modify the favorable prognostic impact of NPM1 mutation. The prognosis of patients with AML presenting marked dysplasia lacking high-risk cytogenetics and NPM1 mutation is uncertain.

Purpose: According to current diagnostic criteria, mantle cell lymphoma (MCL) encompasses the usual, aggressive variants and rare, nonnodal cases with monoclonal asymptomatic lymphocytosis, cyclin D1-positive (MALD1). We aimed to understand the biology behind this clinical heterogeneity and to identify markers for adequate identification of MALD1 cases.

Experimental Design: We compared 17 typical MCL cases with a homogeneous group of 13 untreated MALD1 cases (median follow-up, 71 months).

Histone deacetylases (HDACs) play a key role in the regulation of acetylation status not only of histones but also of many other non-histone proteins involved in cell cycle regulation, differentiation or apoptosis. Therefore, histone deacetylase inhibitors (HDACi) have emerged as promising anticancer agents. Herein, we report the characterization of apoptosis in B-cell chronic lymphocytic leukemia (CLL) induced by two HDACi, Kendine 92 and SAHA.

Background And Objectives: Persistent polyclonal B-cell lymphocytosis (PPBL) is a rare entity, presenting especially in adult smoker women. It is characterized by an increase of serum IgM, DR7-HLA haplotype, cytogenetic abnormalities and multiple IgH/BCL-2 rearrangements. To date, it has not been elucidated whether this is a benign or premalignant disorder.

Retrospective series have reported many clinical and biological significant prognostic factors in chronic lymphocytic leukemia (CLL). We describe a prospective cohort of 135 patients with CLL homogeneously studied at diagnosis for prognostic factors. Biological variables analyzed were CD38 and ZAP-70 expression, fluorescence in situ hybridization (FISH) for 13q-, +12, 11q-, and 17p-, and conventional cytogenetics.

Background: The phosphatidylinositol-3-kinase/Akt pathway has been described to be critical in the survival of chronic lymphocytic leukemia cells. In this study we analyzed the effect of two selective chemical inhibitors of Akt (Akti-1/2 and A-443654) on the survival of chronic lymphocytic leukemia cells.

Design And Methods: Using cytometry we studied the cytotoxic effects of Akt inhibitors on peripheral B and T lymphocytes from patients with chronic lymphocytic leukemia and from healthy donors.

Background: Cold ischemia time and the presence of postoperative hepatic arterial thrombosis have been associated with biliary complications (BC) after liver transplantation. An ABO-incompatible blood group has also been suggested as a factor for predisposal towards BC. However, the influence of Rh nonidentity has not been studied previously.
