Chronic lymphocytic leukemia is a disease of the elderly, and despite major advances in treatment, remains incurable. The Cancer Registry of Norway has registered data on patients with chronic lymphocytic leukemia since 1953. We aimed to analyze trends in incidence and survival of chronic lymphocytic leukemia in Norway. We identified 7664 patients reported with chronic lymphocytic leukemia to the registry between 1953 and 2012. We gathered information on sex, age at diagnosis, date of death and basis for diagnosis...

Pneumocystis jirovecii pneumonia is a known complication in patients with chronic lymphocytic leukemia who are treated with fludarabine-based chemotherapy; however, it is extremely uncommon in treatment naïve patients. Here we report a case of Pneumocystis jirovecii pneumonia in a patient with untreated chronic lymphocytic leukemia.

REVIEW
Phu Tran, Cham Nguyen, Samuel J Klempner
Phosphatidylinositol-3-kinase (PI3K) pathway signaling is an established oncogenic signal transduction pathway implicated in multiple malignancies. Therapeutic targeting of PI3K pathway components has improved outcomes in chronic lymphocytic leukemia, kidney cancer, breast cancer, and neuroendocrine tumors. Gastric cancers harbor some of the highest rates of oncogenic alterations in PI3K but attempts to translate this genomic observation have met with limited clinical success and novel approaches are needed...

The paper continues the series of publications from the International Nuclear Workers Study cohort (INWORKS) that comprises 308,297 workers from France, the United Kingdom and the United States, providing 8.2 million person-years of observation from a combined follow-up period (at earliest 1944 to at latest 2005). These workers' external radiation exposures were primarily to photons, resulting in an estimated average career absorbed dose to the colon of 17.4 milligray. The association between cumulative ionizing radiation dose and cancer mortality was evaluated in general relative risk models that describe modification of the excess relative risk (ERR) per gray (Gy) by time since exposure and age at exposure...

The prognosis of chronic lymphocytic leukemia (CLL) is very heterogeneous. Therefore, a plethora of prognostic factors has been identified to allow a better prediction of the individual prognosis of a given patient. The clinical staging systems by Rai and Binet have been the backbone of clinical management for several decades. The advent of genetic and biochemical markers, as well as next-generation sequencing has provided several markers that can predict the prognosis of patients with CLL. Using this knowledge, several scores have been created to improve predicting overall survival and/or treatment-free survival...

A 61-year-old man with a history of chronic lymphocytic leukemia (CLL) presents with complaints of worsening fatigue and night sweats. He was diagnosed with CLL 3 years ago on routine blood count testing. He has no major medical comorbidities. On examination, he has several 2- to 3-cm lymph nodes in the cervical and axillary area. Spleen is palpable 5 cm below the costal margin. Blood counts show lymphocytosis with thrombocytopenia and anemia. Prognostic markers include deletion 13q by fluorescence in situ hybridization analysis and mutated IGHV You are asked by the hematology fellow you are supervising about the best treatment of this patient...

The advent of novel small-molecule inhibitors has transformed the treatment approaches for patients with chronic lymphocytic leukemia (CLL). These therapies are becoming increasingly used in patients with relapsed disease, patients with 17p deletion, and, as of recently, also in the frontline setting for previously untreated patients with CLL. Moreover, many of these are oral therapies that are significantly less myelosuppressive than chemoimmunotherapy. However, these agents have their own set of unique toxicities with which providers must gain familiarity...

It is an unprecedented time for the treatment of patients with chronic lymphocytic leukemia (CLL) with the recent approval of several targeted agents for use in frontline, relapsed, refractory, and high-risk disease. Traditionally, frontline management of CLL has been a combination of chemotherapy (fludarabine, cyclophosphamide, bendamustine, or chlorambucil) with an anti-CD20 monoclonal antibody (rituximab, ofatumumab, obinutuzumab). The current landscape is rapidly evolving with the advent of therapies that demonstrate selective inhibition of important pathways necessary for CLL proliferation and survival...

Pure red cell aplasia (PRCA) is a syndrome defined by a normocytic normochromic anemia with severe reticulocytopenia and marked reduction or absence of erythroid precursors from the bone marrow. Diamond-Blackfan anemia is a congenital form of PRCA. Acquired PRCA may be either a primary disorder or secondary to some other disorder or agent. Primary acquired PRCA is an autoimmune disorder that is frequently antibody-mediated. Myelodysplastic syndromes may also present with the morphologic appearance of PRCA. Secondary acquired PRCA may be associated with collagen vascular/autoimmune disorders such as systemic lupus erythematosus; lymphoproliferative disorders such as chronic lymphocytic leukemia or large granular lymphocyte leukemia; infections, particularly B19 parvovirus; thymoma and other solid tumors; or a variety of other disorders, drugs, or toxic agents...

Characteristic chromosomal translocations are found to be associated with subtypes of B-cell non-Hodgkin lymphoma (NHL), for example t(8;14)(q24;q32) and Burkitt lymphoma, t(14;18)(q32;q21) and follicular lymphoma, and t(11;14)(q13;q32) in mantle cell lymphoma. Only few recurrent cytogenetic aberrations have been identified in the T-cell NHL and the best known is the ALK gene translocation t(2;5)(p23;q35) in anaplastic large cell lymphoma. Since lymph node or other tissue is seldom submitted for conventional cytogenetics study, alternative approaches for translocation detection are polymerase chain reaction (PCR) or fluorescence in situ hybridization (FISH)...

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...

Objective: The correlation between immunosuppression-associated skin cancer and lymphoma has been well established. This includes squamous cell carcinoma and chronic lymphocytic leukemia. When a lesion requires excision, reconstruction can be challenging based on the depth and size of the tumor. We present a patient with chronic lymphocytic leukemia and invasive squamous cell carcinoma of the scalp that extended through the calvarium to the dura mater. His tumors were badly neglected for a long period of time and presented at an advanced stage...

Bleeding because of impaired platelet function is a major side effect of the Bruton's tyrosine kinase (BTK) inhibitor ibrutinib. We quantitatively assessed ristocetin-induced platelet aggregation (RIPA) in 64 patients with chronic lymphocytic leukemia (CLL) under ibrutinib at 287 time points. Eighty-seven bleeding episodes in 39 patients were registered (85 Common Toxicity Criteria (CTC) grade 1 or 2, 2 CTC grade 3) during a median observation period of 10.9 months. At times of bleeding, RIPA values were significantly lower (14 vs 28 U; P<0...

In chronic lymphocytic leukemia (CLL) the occurrence and the impact of antibody responses toward tumor-derived antigens are largely unexplored. Our serological proteomic data show that antibodies toward 47 identified antigens are detectable in 29 out of 35 patients (83%) with untreated CLL. The glycolytic enzyme alpha-enolase (ENO1) is the most frequently recognized antigen (i.e. 54% of CLL sera). We show that ENO1 is upregulated in the proliferating B-cell fraction of CLL lymph nodes. In CLL cells of the peripheral blood, ENO1 is exclusively expressed at the intracellular level, whereas it is exposed on the surface of apoptotic leukemic cells...

AIMS: Richter transformation (RT) occurs in 5-10% of patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) and is associated with a poor outcome. Histologic manifestations of RT are variable and include an increase in the proportion of large cells including prolymphocytes, immunoblasts and other pleomorphic cells along with an increased proliferation rate and often necrosis. Rarely, superimposed Herpes simplex virus (HSV) infection involving lymph nodes in patients with CLL/SLL may mimic RT clinically and histologically...

Bacterial mycetoma is a neglected disease mainly observed in tropical area countries and typically associated with rural conditions, making its presence in developed countries of temperate climate areas rare. However, we report the first case of an autochthonous mycetoma case in continental France that originated from a new Nocardia species. A Gram-positive filamentous bacterium (OFN 14.177(T)) was isolated from a pus sample from the mycetoma of a male French patient 92 years old suffering from chronic lymphocytic leukemia...

B-cell lymphoma 2 (BCL2)-type proteins are key regulators of the intrinsic or mitochondrial pathway for apoptosis. Since escape from apoptosis is one the main 'hallmarks of cancer', BCL2 inhibitors have emerged as promising therapeutic agents for diverse lymphoid malignancies, particularly chronic lymphocytic leukemia (CLL). Multiple clinical trials have shown efficacy of these agents in patients with relapsed/refractory disease with a favorable toxicity profile. Moreover, some clinical trials indicate that combination with monoclonal antibodies and other novel agents may enhance their effect...

Immunoglobulin (IG) gene repertoire restrictions strongly support antigen selection in the pathogenesis of chronic lymphocytic leukemia (CLL). Given the emerging multifarious interactions between CLL and bystander T cells, we sought to determine whether antigen(s) are also selecting T cells in CLL. We performed a large-scale, next-generation sequencing (NGS) study of the T-cell repertoire, focusing on major stereotyped subsets representing CLL subgroups with undisputed antigenic drive, but also included patients carrying non-subset IG rearrangements to seek for T-cell immunogenetic signatures ubiquitous in CLL...
