INTRODUCTION: Chronic lymphocytic leukemia (CLL) is a disorder of mature but dysfunctional monoclonal B cells. Microenvironment, antigenic stimulation and genetical mutations are demonstrated in etiopathogenesis. We aimed to evaluate the expression of CD11c in patients with CLL and its possible clinical significance. METHODS: Data of 259 patients with CLL between 2010 and 2016 in Trakya University Faculty of Medicine, including age at diagnosis, sex, whole blood count, stage, percentage of CLL cells in bone marrow, line of treatments, development of Richter's transformation and secondary tumors, autoimmune complications, IgG level, prognostic cytogenetic analysis, and length of survival were recorded from files...

Genomic analysis has greatly influenced the diagnosis and clinical management of patients affected by diverse forms of hematologic malignancies. Here we review how genetic alterations define subclasses of patients with acute leukemias, myelodysplastic syndromes (MDS), myeloproliferative neoplasms (MPNs), non-Hodgkin lymphomas and classical Hodgkin lymphoma. These include new subtypes of acute myeloid leukemia defined by mutations in RUNX1 or BCR-ABL1 translocations as well as a constellation of somatic structural DNA alterations in acute lymphoblastic leukemia...

The incidence of serum sickness following treatment of CLL with obinutuzumab has not been fully characterized, but is likely rare. Consideration should be given to this diagnosis in appropriate circumstances so that effective corticosteroid therapy can be initiated to alleviate inflammatory symptoms and organ dysfunction in a timely manner.

The ultimate cause of death for most patients with newly diagnosed chronic lymphocytic leukaemia (CLL) and its relationship to co-morbid health conditions is poorly defined. We conducted a prospective cohort study that systematically followed 1143 patients diagnosed with CLL between June 2002 and November 2014. Comorbid health conditions at the time of CLL diagnosis and their relationship to survival and cause of death were evaluated. Collectively, 1061 (93%) patients had at least one co-morbid health condition at the time of CLL diagnosis (median number 3)...

With a median age of 72 years at first diagnosis, chronic lymphocytic leukaemia (CLL) is a disease of the elderly. At this age, many patients cannot bear an intensive chemoimmunotherapy like fludarabine, cyclophosphamide and rituximab (FCR), and therapeutic decisions are commonly complicated by a high burden of accompanying comorbidities. Clinical trials, on the other hand, are mostly designed to include a far healthier and younger trial population, with a median age in most studies well below 70 years, leading to an insufficient reflection of clinical reality...

Invariant natural killer T (iNKT)/natural killer (NK)/cytokine-induced killer (CIK) cells are important for immune surveillance. (I) Novel combinations of antibody 6B11 (targeting the Vα24-Jα18-invariant T-cell receptor) with CD4/CD8/CD1d/Vα24 for iNKT subset detection and "T/NK cell-like"-iNKT subsets were defined. Compared with healthy peripheral blood mononuclear cells (MNC) (significantly) lower proportions of iNKT cells (6B11/6B11CD3/6B11CD161), NK cells (CD3CD56/CD3CD161), and CIK cells (CD3CD56/CD3CD161) were found in peripheral blood MNC from acute myeloid (AML)/acute myeloid, lymphoid (ALL)/chronic lymphoid leukemia (CLL) patients in acute disease stages...

Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy. Simultaneous involvement of the thyroid gland by multiple malignancies, is a rare occurrence. Similarly, primary thyroid lymphomas are also rare. We are reporting a rare case of a dual thyroid malignancy; PTC with secondary thyroid involvement by chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), diagnosed on cytology and confirmed with flow cytometry, histology and immunohistochemistry. Imaging showed two hypermetabolic nodules, one in left parotid gland, and the other in the thyroid isthmus...

Chronic lymphocytic leukemia (CLL) is the most common adult leukemia and it typically afflicts older adults, with a median age at diagnosis of 71. Traditional treatments for CLL have included chemotherapy, which can often be difficult for older patients to tolerate. Given the variability in fitness, cognition and comorbidities amongst older patients, a geriatric evaluation should be considered prior to commencement of cytotoxic therapy. More recently, novel oral agents are proving to be both safe and effective in this population, redefining the field of CLL therapy...

Unlike in Western countries, chronic lymphocytic leukemia (CLL) is a rare lymphoid malignancy in Japan, and its clinical features remain to be elucidated in the Japanese population. Therefore, we retrospectively analyzed 29 Japanese CLL patients newly diagnosed at our institute. Seventeen (59%) were male, and their median age was 62 years. With a median follow-up period from diagnosis of 69 months (range, 3-170 months), 9 patients received some form of treatment for CLL. Three patients died of disease progression with or without infection (n=2) or skin cancer (n=1)...

Galectin-1 (Gal-1) is known to regulate cell signaling within the immune system and may be a target for new anticancer immune therapy. In patients with chronic lymphocytic leukemia (CLL) and classical Hodgkin lymphoma (cHL), high levels of Gal-1 within the tumor microenvironment were associated with worse disease state or poor outcome. Gal-1 can be secreted from cells by an unknown mechanism, and levels in blood samples were associated with high tumor burden and worse disease state in cHL and CLL patients. However, serum levels of Gal-1 have never been investigated in patients with multiple myeloma (MM)...

Monoclonal B-cell lymphocytosis (MBL) is an asymptomatic clinical entity characterized by the proliferation of monoclonal B cells not meeting the diagnosis criteria for chronic lymphocytic leukemia (CLL). MBL may precede the development of CLL, but the molecular mechanisms responsible for disease progression and evolution are not completely known. Telomeres are usually short in CLL and their attrition may contribute to disease evolution. Here, we determined the telomere lengths of CD5+CD19+ cells in MBL, CLL, and healthy volunteers...
