Hematological malignancies in Ukraine in post-Chernobyl era: sources of data and their preliminary analysis

AbstractThe major sources of the data on the hematological malignancies in the post-Chernobyl period in the regions of Ukraine differing by the levels of the residual contamination with radionuclides have been analyzed. According to the data collected from the primary hematological facilities in Ukraine in 2010 –2017, the incidence of lymphoid neoplasms from mature B cells, acute myeloid leukemia, and multiple myeloma in the most contaminated regions was higher than in the less contaminated ones. For the first time, the relative contribution of the several specific types of leukemia in the total diagnose d hematological malignancies has been analyzed throughout 1997–2017 based on the in-house database compiled by the Reference Laboratory of RE Kavetsky Institute of Experimental Pathology, Oncology and Radiobiology, the National Academy of Sciences of Ukraine. In 2011–2017, the Reference Laborato ry provided the diagnostic studies in about 26% of all Ukrainian patients with tumors of hematopoietic and lymphoid tissues (34% of patients with different forms of acute and chronic leukemia). The increased proportion of acute myeloid leukemia and chronic lymphocytic leukemia in the total diagnosed cases of overall leukemia in the patients from contaminated regions has been demonstrated following Chernobyl accident.

ConclusionVenetoclax therapy in a real-world cohort offered modest benefits in heavily pretreated patients. Adverse events were observed at a greater incidence than in the clinical trials. A wide heterogeneity of venetoclax dose escalation, multiagent combinations, and timing of initiation were identified and require investigation in subsequent clinical trials.

ConclusionVenetoclax therapy in a real-world cohort offered modest benefits in heavily-pretreated patients. Adverse events were observed at higher incidence compared to clinical trials. A wide heterogeneity of venetoclax dose escalation, multi-agent combinations, and timing of initiation were identified and would best be investigated in subsequent clinical trials.

rer S Abstract In this review article, we present recent updates on the hematological tumor microenvironment following the 3rd Scientific Workshop on the Haematological Tumour Microenvironment and its Therapeutic Targeting organized by the European School of Hematology, which took place at the Francis Crick Institute in London in February 2019. This review article is focused on recent scientific advances highlighted in the invited presentations at the meeting, which encompass the normal and malignant niches supporting hematopoietic stem cells and their progeny. Therefore, for the sake of focus it does not discuss ...

Auer rods were first described in the cytoplasm of leukemia blasts by John Auer in 1906. Auer rods are commonly seen in myeloid progenitors, and serve as a diagnostic morphological feature of acute myeloid leukemia (AML) [1]. The differential diagnosis of hematopoietic neoplasms relies on the detection of cytoplasmic inclusions resembling Auer rods. Auer rod-like inclusions have been described in multiple myeloma [2], prolymphocytic leukemia (PLL) [3], B-cell acute lymphoblastic leukemia [4], chronic lymphocytic leukemia [4], splenic lymphoma [5] and nodal marginal zone lymphoma [6], which are quite distinct from the needl...

AbstractLeukemia is one of the most aggressive hematological malignancies. Leukemia stem cells account for the poor prognosis and relapse of the disease. Decades of investigations have been performed to figure out how to eradicate the leukemia stem cells. It has also been known that cancer cells especially solid cancer cells use energy differently than most of the cell types. The same thing happens to leukemia. Since there are metabolic differences between the hematopoietic stem cells and their immediate descendants, we aim at manipulating the energy sources with which that could have an effect on leukemia stem cells while...

Markus Hartl* and Rainer Schneider Center of Molecular Biosciences (CMBI), Institute of Biochemistry, University of Innsbruck, Innsbruck, Austria The neuronal proteins GAP43 (neuromodulin), MARCKS, and BASP1 are highly expressed in the growth cones of nerve cells where they are involved in signal transmission and cytoskeleton organization. Although their primary structures are unrelated, these signaling proteins share several structural properties like fatty acid modification, and the presence of cationic effector domains. GAP43, MARCKS, and BASP1 bind to cell membrane phospholipids, a process reversibly regulate...

Recent data has provided novel insights in elucidating the roles of SEs in many diseases, including cancer. Many mechanisms involved in tumorigenesis and progression, ranging from internal gene mutation and rearrangement to external damage and inducement, have been demonstrated to be highly associated with SEs. Moreover, translocation, formation, deletion, or duplication of SEs themselves co...

Conclusions: CAR T cell therapies have demonstrated the clinical benefits of harnessing our body's own defenses to combat tumor cells. Similar research is being conducted on lesser known modifications and gene-modified immune cells, which we highlight in this review. Introduction Chimeric antigen receptors and engineered T cell receptors (based on previously identified high affinity T cell receptors) function by redirecting T cells to a predefined tumor-specific (or tumor-associated) target. Most of these modifications use retroviral or lentiviral vectors to integrate the construct, and most of the receptors ...
