Early Prediction and Streamline of Nucleophosmin Mutation Status in Acute Myeloid Leukemia Using Cup-Like Nuclear Morphology.

: With the advent of novel therapies for nucleophosmin gene ()-mutated acute myeloid leukemia (AML), there is a growing need for the reliable prediction of mutations. This study explored the role of cytomorphological features in the early prediction of -mutated AML. : Altogether, 212 de novo AML cases with normal karyotypes, diagnosed and treated at a single institution within 5 years (2018-2023), were retrospectively evaluated.

Incidence, risk factors, and outcome of asymptomatic central nervous system involvement in adult patients with acute myeloid leukemia.

Examination of central nervous system (CNS) involvement is not routine diagnostic practice in adult patients with acute myeloid leukemia (AML). Therefore, many asymptomatic patients with CNS involvement might go undetected. The effect of CNS involvement on the AML disease course is not well defined, with conflicting results regarding clinical outcome.

Correlation between leukocyte-platelet aggregates and thrombosis in myeloproliferative neoplasms.

Introduction: The impact of activated blood and endothelial cells on the thrombosis in myeloproliferative neoplasms (MPN) has not yet been clarified. We prospectively analyzed correlation between circulating leukocyte-platelet aggregates and soluble selectins to thrombosis occurrence in MPN, in the context of standard and cardiovascular risk factors, and different clinical and biological characteristics.

Methods: Flow cytometric analysis of neutrophil-platelet (Neu-Plt) and monocyte-platelet (Mo-Plt) aggregates in peripheral blood, as well as quantification of soluble E-/L-/P-selectins by enzyme immunoassay, was performed on 95 newly diagnosed MPN patients.

CD56-Positive Acute Myeloid Leukemia Following Treatment of Hairy Cell Leukemia with Cladribine - Report of 2 Cases and Review of the Literature.

Good's syndrome with increasing γδ T-lymphocyte subpopulation: A case report.

Introduction: Good's syndrome is a rare cause of adult-onset immunodeficiency associated with thymoma. Good's syndrome should be considered in patients older than 40 years with the history of frequent infections. An abnormal immunoglobulin profile needs further investigation and flow cytometry which is crucial for establishing the diagno- sis of Good's syndrome.

Proinflammatory Cytokine IL-6 and JAK-STAT Signaling Pathway in Myeloproliferative Neoplasms.

The recent JAK1/2 inhibitor trial in myeloproliferative neoplasms (MPNs) showed that reducing inflammation can be more beneficial than targeting gene mutants. We evaluated the proinflammatory IL-6 cytokine and JAK-STAT signaling pathway related genes in circulating CD34(+) cells of MPNs. Regarding laboratory data, leukocytosis has been observed in polycythemia vera (PV) and JAK2V617F mutation positive versus negative primary myelofibrosis (PMF) patients.

Gene expression profile of circulating CD34(+) cells and granulocytes in chronic myeloid leukemia.

Purpose: We compared the gene expression profile of peripheral blood CD34(+) cells and granulocytes in subjects with chronic myeloid leukemia (CML), with the accent on signaling pathways affected by BCR-ABL oncogene.

Methods: The microarray analyses have been performed in circulating CD34(+) cells and granulocytes from peripheral blood of 7 subjects with CML and 7 healthy donors. All studied BCR-ABL positive CML patients were in chronic phase, with a mean value of 2012±SD of CD34(+)cells/μl in peripheral blood.

The role of immunophenotyping in differential diagnosis of chronic lymphocytic leukemia.

Introduction: Accurate diagnosis of chronic lymphocytic leukemia (CLL) acquires immunophenotyping by flow cytometry in order to facilitate differential diagnosis between CLL and other mature B-cell neoplasms (MBCN).

Objective: The aim of this study was to define immunological profile of CLL cells.

Methods: Immunophenotyping by flow cytometry was performed on peripheral blood specimens at diagnosis in the group of 211 patients with de novo MBCN.

The emergence of non-secretory multiple myeloma during the non-cytotoxic treatment of essential thrombocythemia: a case report.

Introduction: The emergence of multiple myeloma as a second malignancy in patients with essential thrombocythemia is extremely rare. Several cases have been published so far, pointing out the impact of a cytotoxic effect during treatment of essential thrombocythemia on the development of multiple myeloma.

Case Presentation: We report the case of a 52-year-old Caucasian man who presented to our hospital because of leukocytosis, a slightly decreased hemoglobin level and thrombocytosis.

International Society of Thrombosis and Hemostasis Scoring System for disseminated intravascular coagulation ≥ 6: a new predictor of hemorrhagic early death in acute promyelocytic leukemia.

High-hemorrhagic early death (ED) rate is a major impediment in the managing of acute promyelocytic leukemia (APL). In our group of 56 newly diagnosed APL patients, ED occurred in 12 subjects, due to endocranial bleeding (8/12), differentiation syndrome (2/12), or infection (2/12). Predictors of hemorrhagic ED were as follows: white blood cells count ≥ 20 × 10(9)/L (P = 0.

Concomitant aberrant methylation of p15 and MGMT genes in acute myeloid leukemia: association with a particular immunophenotype of blast cells.

In this study, methylation-specific polymerase chain reaction (MS-PCR) was used to define the methylation status of the target promoter sequences of p15 and MGMT genes in the group of 21 adult patients with acute myeloid leukemia (AML). The incidence of aberrant hypermethylation of p15 gene (71 %) was higher comparing to MGMT gene (33 %), whereas concomitant methylation of both genes had 24 % of the patients. Although the incidence of cytogenetic abnormalities between the groups with a different methylation status of p15 and/or MGMT genes was not significantly different, we observed general trend of clustering of abnormalities with adverse prognosis into groups with concomitant hypermethylation of both genes and only p15 gene.

Therapy-related acute leukemia in two patients with multiple sclerosis treated with Mitoxantrone.

[Prognostic significance of new biological markers in chronic lymphocytic leukaemia].

Introduction: Chronic lymphocytic leukaemia is a disease with heterogeneous clinical course and outcome. Some patients have a progressive course of the disease and require therapy immediately after the diagnosis, while others have a stable form without the need for treatment. Recently, two new biological markers, the expression of CD38 antigen and ZAP-70 have shown independent significance in the prognosis in CLL patients.

Outcome prediction of advanced mantle cell lymphoma by international prognostic index versus different mantle cell lymphoma indexes: one institution study.

The aim of this study was to evaluate the prognostic significance of international prognostic index (IPI), mantle cell lymphoma IPI (MIPI), simplified MIPI (sMIPI), and MIPI biological (MIPIb), as well as their correlation with immunophenotype, clinical characteristics, and overall survival (OS), in a selected group of 54 patients with advanced-stage mantle cell lymphoma (MCL), treated uniformly with CHOP. Seventeen patients had IV clinical stage (CS), while other 37 had leukemic phase at presentation. Diffuse type of marrow infiltration was verified in 68.
