Two recent studies reported whole-genome sequencing of chronic lymphocytic leukemia (CLL) samples and found repeated mutations in the XPO1 and NOTCH1 genes. XPO1 was found mutated in 2.4% of cases, while NOTCH1 was found mutated in 12.2% or 15.1% of CLL samples. Here we report the results of sequencing of XPO1 and NOTCH1 in 186 CLL cases. Our results confirmed frequency of XPO1 mutations. Howev...
Although chronic lymphocytic leukaemia (CLL) is a B cell malignancy, earlier studies have indicated a role of T cells in tumour growth and disease progression. In particular, the functional silencing of antigen-experienced T cells, called T cell exhaustion, has become implicated in immune evasion in CLL. In this study, we tested whether T cell exhaustion is recapitulated in the TCL1(tg) mouse m...
Chronic lymphocytic leukaemia (CLL) being the commonest subtype of mature B-cell lymphoid neoplasms need to be differentiated correctly from other B-chronic lymphoproliferative disorders (BCLPD). CD200 is an essential marker for prognosis and diagnosis CLL. Sixty patients diagnosed with BCLPD were evaluated expression eight-colour flow cytometry. An integration modified Matutes score applied CL...
PURPOSE Few biological prognosticators are useful for prediction of Richter syndrome (RS), representing the transformation of chronic lymphocytic leukemia (CLL) to aggressive lymphoma. Stereotyped B-cell receptors (BCR) may have prognostic effect in CLL progression. We tested the prognostic effect of stereotyped BCR for predicting RS transformation. EXPERIMENTAL DESIGN The prevalence of stere...
Peripheral blood chronic lymphocytic leukemia (CLL) cells are replicationally quiescent mature B-cells. In short-term cultures, supporting stromal cells provide a survival advantage to CLL cells by inducing transcription and translation without promoting proliferation. We hypothesized that the stromal microenvironment augments malignant B cells' metabolism to enable the cells to cope with their...
Chronic lymphocytic leukemia (CLL) cells are provided with essential survival and proliferative signals in the lymph node microenvironment. Here, CLL cells engage in various interactions with bystander cells such as T cells and macrophages. Phenotypically distinct types of tumor infiltrating macrophages can either be tumor supportive (M2) or play a role in tumor immune surveillance (M1). Althou...
conclusions it was demonstrated that the presence of del6q21 in b-cll patients indicates poor prognosis and on the contrary, presence of del17p13 points at the good prognostic value of the disease. results deletion of 17p13 was found in 11 (16.6%) and deletion 6q21 was present in 5 (7.5%). statistical analyses were performed to investigate the correlation of these molecular-cytogenetic findings...
Introduction. Determining the cause of shoulder pain is usually a challenge as many problems, such rheumatoid arthritis, osteoarthritis, osteonecrosis, rotator cuff arthropathy, traumatic fractures, conditions cervical vertebra, and neo-plasms, can produce similar symptoms. The diagnosis regarded incidental, however, chronic lymphocytic leukemia (CLL) by histopathological evaluation performed o...
The U.S. government recently implemented rules for awarding compensation to individuals with cancer who were exposed to ionizing radiation while working in the nuclear weapons complex. Under these rules, chronic lymphocytic leukemia (CLL) is considered to be a nonradiogenic form of cancer. In other words, workers who develop CLL automatically have their compensation claim rejected because the c...
PURPOSE Despite advances in the treatment of chronic lymphocytic leukemia (CLL), the disease remains incurable with standard therapies and relapse is inevitable. A growing body of evidence indicates that alterations in the adhesion properties of neoplastic cells play a pivotal role in the development and progression of CLL. EXPERIMENTAL DESIGN The expression of 71 cell surface molecules was e...
