The heterogeneity of the clinical course of chronic lymphocytic leukemia (CLL) ranges from an indolent course, where patients do not require therapy for many years, to a very aggressive disease, where treatment is required soon after diagnosis and relapses may occur early. The improved tools for prognostication allow predicting the outcome of patients with increasing reliability. Some markers also allow selecting more specific therapies with improved activity in the presence of certain genetic or clinical features of CLL...

INTRODUCTION: Depending on the location and the extent of disease, mature B-cell disorders can be divided into 
benign monoclonal B-cell lymphocytosis (MBL), chronic 
lymphocytic leukaemia (CLL) and small lymphocytic lymphoma (SLL). Whereas SLL is characterised by its location outside the blood stream, MBL is distinguished from CLL by a monoclonal B-cell count below 5 × 109/l. Due to its low tendency to transform into CLL, correct diagnosis of MBL is essential. We hypothesised that this might not always be the case...

BACKGROUND: Renal failure due to the infiltration of chronic lymphocytic leukemia (CLL) cells into the tubulointerstitial area of the kidney is uncommon. Furthermore, granulomatous interstitial nephritis (GIN) is a rare histological diagnosis in patients undergoing a renal biopsy. We herein report a case of GIN due to the diffuse infiltration of CLL cells in a patient who developed progressive renal failure. CASE PRESENTATION: The patient was a 55-year-old man who had been diagnosed with CLL 4 years earlier and who had been followed up without treatment...

Chronic Lymphocytic Leukaemia (CLL), the most common leukaemia in the Western world, has a characteristic phenotype and prognosis largely defined by the presence of cytogenetic aberrations. The gold standard for detecting these cytogenetic abnormalities is interphase fluorescence in situ hybridisation (FISH) performed on cell smears or tissue sections on glass slides. Fluorescently labelled DNA probes bind to specific chromosomal regions and the signal detected by fluorescent microscopy. Generally only 200 cells are assessed and the limit of sensitivity is 3% positive cells...

Chronic lymphocytic leukemia (CLL) is a common lymphoid malignancy that has a highly variable clinical course. Genomic features as zeta-chain-associated protein kinase 70 (ZAP70) expression and CD38 expression provide further differentiation of disease prognosis. Extensive studies have confirmed the oncogenic activities of IL-9 in lymphoma. The aim of the current study was to investigate the contribution of IL-9 expression to the pathogenesis of CLL and its correlation to other prognostic parameters. This study was conducted on 80 patients at diagnosis with CLL and 80 healthy controls...

Chronic lymphocytic leukemia (CLL) has a highly variable clinical course. About 2-10% of CLL patients develop aggressive histological transformation, most commonly to diffuse large B cell lymphoma (DLBCL), historically called Richter transformation (RT). Clinical features suggestive of RT include elevated LDH and non-specific symptoms such as fever, weight loss, and lymphadenopathy. 18-fluorodeoxyglucose (18-FDG) uptake is increased on PET scan (standardized uptake value max most commonly ≥ 10). PET/CT study can identify optimal site for excisional biopsy, which is the gold standard for RT diagnosis, as well as aid in disease staging and prognostication...

The incidence rate of chronic lymphocytic leukemia (CLL) in the United States is approximately 0.005%; men are at slightly higher risk than women. Bony involvement or pathological fracture rarely occurs in CLL, and it may be the initial presentation. An 85-year-old woman presented with acute respiratory failure secondary to pneumonia. Symptomatology included dyspnea. She was found to have pathological fracture of the femur caused by CLL. The diagnosis of CLL had been made 6 years previously, but the patient had refused therapy...

BACKGROUND: Chronic Lymphocytic Leukemia (CLL) is one of the most common diagnoses made by flow cytometry laboratories. There is no consensus on which markers need to be used in flow cytometry for accurate immunophenotyping. Herein, we investigated the role of markers used in flow cytometry in the distinction between CLL and MCL. METHODS: A total 339 recently diagnosed B lymphoproliferative patient cases were retrospectively studied for their immunophenotypical propoerties using flow cytometry...

BACKGROUND: Plasma cell myeloma (PCM) has been sporadically reported to occur simultaneously or subsequently to mature B lymphoproliferative disorders (LPDs), predominantly chronic lymphocytic leukaemia (CLL). METHODS: We describe the clinical and laboratory findings of a 69-year-old male patient who developed plasma cell leukaemia (PCL) 8 years after an initial diagnosis of a low stage CD5+ B LPD and 3 years after treatment for LPD. RESULTS: The transition from a clinically indolent B LPD to an aggressive PCM was documented by bone marrow (BM) biopsy, while flow cytometric (FC) immunophenotyping conferred additional information by disclosing the co-existence of both disorders in BM and the presence of abnormal monotypic PCs in peripheral blood above PCL levels...

The diagnostic criteria for CLL rely on morphology and immunophenotype. Current approaches have limitations affecting reproducibility and there is no consensus on the role of new markers. The aim of this project was to identify reproducible criteria and consensus on markers recommended for the diagnosis of CLL. ERIC/ESCCA members classified 14 of 35 potential markers as "required" or "recommended" for CLL diagnosis, consensus being defined as >75% and >50% agreement, respectively. An approach to validate "required" markers using normal peripheral blood was developed...

Richter syndrome represents the transformation of chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma into an aggressive large B-cell lymphoma. Skin involvement is exceptionally rare, with <20 cases reported and its presence as the first presentation of CLL/small lymphocytic lymphoma, as an isolated skin lesion has never been described. Primary cutaneous CD4-positive small/medium T-cell lymphoma (CD4 PCSM-TCL) characteristically presents with a dense dermal infiltrate consisting primarily of small-/medium-sized pleomorphic T-cells and less than 30% large pleomorphic cells...

PURPOSE: The LEUKOSPECT study aimed to describe health service utilization and to estimate the direct medical costs (DMCs) of chronic lymphocytic leukemia (CLL) in 2013 in the adult population of three post-Soviet countries - Russia, Ukraine, and Kazakhstan. As oncologic medical care is provided by federal state-owned, specialized medical institutions, the cost estimation in this study primarily informs from a state budget perspective. Patients' contributions to medical costs were not included in the cost evaluation...

BACKGROUND: B-cell chronic lymphocytic leukemia (CLL) is a common type of adult leukemia. It often follows an indolent course and is preceded by monoclonal B-cell lymphocytosis, an asymptomatic condition, however it is not known what causes subjects with this condition to progress to CLL. Hence the discovery of prediagnostic markers has the potential to improve the identification of subjects likely to develop CLL and may also provide insights into the pathogenesis of the disease of potential clinical relevance...

Objectives Traditional prognostic factors have proven insufficient to account for the observed heterogeneity in the clinical behavior of chronic lymphocytic leukemia (CLL). Cryptochrome-1 (CRY-1) is a circadian clock gene essential in maintaining circadian rhythm and regulating cell proliferation. We evaluated CRY-1 gene expression in CLL patients, and assessed its putative role as a prognostic indicator for the clinical course of CLL. Materials and Methods Hundred CLL patients at diagnosis were studied for CRY-1 gene expression by qRT-PCR, and were followed up for assessment of time to first treatment (TFT)...

Tumor lysis syndrome (TLS) is an uncommon but potentially life-threatening complication associated with the treatment of some cancers. If left untreated, TLS may result in acute renal failure, cardiac dysrhythmia, neurologic complications, seizures, or death. Tumor lysis syndrome is most commonly observed in patients with hematologic malignancies with a high proliferation rate undergoing treatment with very effective therapies. In chronic lymphocytic leukemia (CLL), historically, TLS has been observed less often, owing to a low proliferation rate and slow response to chemotherapy...

Secondary neoplasias are well known consequences of radiotherapy or chemotherapy for a primary cancer. In this report, we describe two rare secondary neoplasias occurring in the same patient: a meningioma-like intracranial tumor and high-risk myelodysplastic syndrome (MDS) of donor-cells origin, both diagnosed simultaneously, 8 years after an allogeneic hematopoietic stem cell transplantation (allo-HSCT) for chronic lymphocytic leukemia (CLL). Due to an engraftment failure during the first allo-HSCT of a matched related donor for CLL treatment, the salvage treatment was a second allo-HSCT...
