Influence of Blood Count, Cardiovascular Risks, Inherited Thrombophilia, and JAK2 V617F Burden Allele on Type of Thrombosis in Patients With Philadelphia Chromosome Negative Myeloproliferative Neoplasms.

Introduction: Thrombosis is the most common complication in Philadelphia chromosome negative (Ph-) myeloproliferative neoplasms patients.

Patients And Methods: In a cohort of 258 Ph- myeloproliferative neoplasm patients, the difference between patients with and without thrombosis was analyzed according to genetic thrombophilia factors, JAK2 V617F status and burden allele, blood count, cardiovascular risk factors and age. Patients were also divided in polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) subgroups as well as by the type of thrombosis.

Treatment and outcome of 2904 CML patients from the EUTOS population-based registry.

The European Treatment and Outcome Study (EUTOS) population-based registry includes data of all adult patients newly diagnosed with Philadelphia chromosome-positive and/or BCR-ABL1+ chronic myeloid leukemia (CML) in 20 predefined countries and regions of Europe. Registration time ranged from 12 to 60 months between January 2008 and December 2013. Median age was 55 years and median observation time was 29 months.

Comparison of Branded and Generic Imatinib Plasma Concentrations in Patients With Chronic Myelogenous Leukemia: Unicentric Study.

Introduction: For over a decade, imatinib has been the first-line treatment of Philadelphia chromosome-positive chronic myeloid leukemia (CML). Doubts on the bioequivalence and bioavailability of emerging generic compounds have been expressed. Adequate imatinib plasma concentration ([IPC] ≥1000 μmol/L) is associated with a better chance of optimal treatment response in patients with CML.

High-dose ifosfamide and mitoxantrone (HDIM) in patients with relapsed or refractory Hodgkin's lymphoma.

Relapsed/refractory Hodgkin's lymphoma (HL) is treated with salvage chemotherapy and autologous stem cell transplantation (ASCT). Optimal chemotherapy is unknown. We retrospectively analyzed outcomes of 58 patients treated with 2 cycles of high-dose ifosfamide and mitoxantrone (HDIM).

Immunoglobulin heavy/light chain analysis enhances the detection of residual disease and monitoring of multiple myeloma patients.

Aim: To evaluate the clinical utility of incorporating a novel heavy/light chain immunoassay (HLC) into the existing methods for the assessment of multiple myeloma (MM) patients.

Methods: Convenience sera samples from 90 previously treated IgG and IgA MM patients in different disease stages were analyzed. The study was conducted in Clinical Hospital Center Zagreb between 2011 and 2013.

The EUTOS population-based registry: incidence and clinical characteristics of 2904 CML patients in 20 European Countries.

This population-based registry was designed to provide robust and updated information on the characteristics and the epidemiology of chronic myeloid leukemia (CML). All cases of newly diagnosed Philadelphia positive, BCR-ABL1+ CML that occurred in a sample of 92.5 million adults living in 20 European countries, were registered over a median period of 39 months.

Efficacy and safety of colistin in the treatment of infections caused by multidrug-resistant Pseudomonas aeruginosa in patients with hematologic malignancy: a matched pair analysis.

Objective: A rise in infections with multidrug-resistant Pseudomonas aeruginosa (MDR-PA) is a significant contributor to increased morbidity and mortality of patients with hematologic malignancies. The aim of this study was to determine the efficacy and safety of colistin (colistimethate sodium) in the treatment of serious infections caused by MDR-PA in these patients.

Patients And Methods: A matched pair analysis of renal function, toxicities, and outcome of 26 patients receiving colistin and control subjects was done.

Collection and composition of autologous peripheral blood stem cells graft in patients with acute myeloid leukemia: influence on hematopoietic recovery and outcome.

Hematopoietic stem cell (HSC) transplantation is a standard approach in the treatment of hematological malignant diseases. For the last 15 years the main source of cells for transplantation have been peripheral blood stem cells (PBSC). With the availability of hematopoietic growth factors and understanding the advantages of treatment with PBSC, the application of bone marrow (BM) was supplanted.

[Twenty years of severe aplastic anemia treatment at Department of Hematology, University Department of Medicine, Zagreb University Hospital Center, Zagreb, Croatia].

Aplastic anemia is a bone marrow disease characterized by marrow aplasia and pancytopenia. Because hematopoietic stem cell transplantation (HSCT) cures severe aplastic anemia (SAA), it is the treatment of choice for younger patients. For many years, antithymocyte globulin (ATG) has been standard immunosuppressive therapy for those aplastic anemia patients that have no HLA matched related donor.

[Treatment of acute leukemia with allogeneic stem cell transplantation].

Allogeneic hematopoietic stem cell transplantation is a standard therapeutic option in the treatment of patients with malignant hematologic diseases and some acquired or inherited nonmalignant hematologic disorders. It is the most efficacious method for eradication of acute leukemia, its efficacy being described by DFS (Disease Free Survival) and OS (Overall Survival), however, still associated with a high Transplant Related Mortality (TRM) rate. At Department of Hematology, University Department of Medicine, Zagreb University Hospital Center, bone marrow transplantation has been a standard procedure since 1983.

[Current approach to diagnosis and treatment of acute leukemia in adults].

Current classification of acute leukemia is based on morphology, immunophenotyping, cytogenetic and molecular abnormalities of leukemic cells. All these techniques have a diagnostic and prognostic value. Molecular abnormalities in many cases suggest the pathogenesis of acute leukemia, but also point to the key site of genetic abnormalities that may be targeted with the therapy.

Treatment of relapsed or refractory aggressive non-hodgkin lymphoma with two ifosfamide-based regimens, IMVP and ICE.

We report the outcomes of 45 patients with relapsed or refractory aggressive non-Hodgkin's lymphoma (NHL) treated with a combination of ifosfamide, carboplatinum and etoposide (ICE) and 28 patients treated with a combination of ifosfamide, methotrexate and etoposide (IMVP) during two 5-year periods. The response rate (RR) to ICE was 47%, 2-year overall survival (OS) 31% and 2-year event-free survival (EFS) 22%. These results were similar to those obtained with IMVP (RR 39%, 2-year OS 23%, 2-year EFS 13%; p=0.

Biological features and outcome of biphenotypic acute leukemia: a case series.

Background: Biphenotypic acute leukemia (BAL) is a distinct entity that is immunophenotypically defined by the European Group for the Immunological Classification of Leukemia (EGIL) scoring system and accounts for less than 5% of all acute leukemia cases. Since it is a rare and heterogeneous form of acute leukemia with an allegedly poor outcome, there is no consensus on the best treatment approach in these patients. Our objective was to analyze the biological features and outcome of patients diagnosed with BAL in our institution.

[Anagrelide for treatment of patients with essential thrombocythaemia].

Anagrelide is an imidazokinazoline derivate that reduces platelet production by interfering with megakaryocyte proliferation and maturation. As a non-cytostatic drug it selectively affects megakaryocyte lineage and therefore anemia and leukocytopenia are not likely to occur. This makes anagrelide adequate for the treatment of chronic myeloproliferative disorders characterized by marked thrombocytemia.

Gemcitabine in the treatment of relapsed and refractory Hodgkin's disease.

Background: Patients with refractory Hodgkin's disease or relapsing after high-dose therapy and autografting have a poor prognosis. Here, we present our experiences with gemcitabine in this setting.

Patients And Methods: We treated 14 patients with relapsed or refractory Hodgkin's disease with gemcitabine.

[Rituximab in the treatment of indolent non-Hodgkin's lymphoma].

Indolent Non-Hodgkin's lymphomas (NHL) are a group of slowly progressive immune system malignancies that cannot be cured with conventional treatment. Rituximab is an anti-CD20 monoclonal antibody that has recently become a part of the standard treatment of B-cell lymphoid malignancies. Here we present our experience in 25 patients with indolent NHL treated with rituximab with or without chemotherapy.

[Treatment of chronic myeloid leukemia with imatinib in the accelerated stage of the disease].

Philadelphia chromosome positive chronic myeloid leukemia (Ph+ CML), in advanced stage of disease, is resistant to standard chemotherapy. Imatinib was found to be effective in these patients. This paper shows our preliminary results.

Aim: To evaluate the role of surgical resection in the treatment of patients with primary gastrointestinal non-Hodgkin s lymphoma in our institution.

Method: The retrospective study included 79 patients with a histologically confirmed primary gastrointestinal lymphoma, who were diagnosed and treated for the disease in the 1978-1997 period. According to the treatment modality, the patients were divided into surgically treated and surgically non-treated group.

Combination of ifosfamide, methotrexate, and etoposide (IMVP) as a salvage therapy for relapsed and refractory aggressive non-Hodgkin lymphoma: retrospective study.

Aim: There are contradictory reports on the outcomes of IMVP (ifosfamide, methotrexate, and etoposide) treatment in patients with aggressive non-Hodgkin s lymphomas. Our aim was to evaluate retrospectively the results of this treatment in our institution.

Methods: Twenty eight patients with refractory or relapsed aggressive non-Hodgkin s lymphomas received IMVP between April 1997 and June 2001.

Molecular monitoring of minimal residual disease in acute promyelocytic leukemia by the polymerase chain reaction assay for the PML/RAR alpha (retinoic acid receptor-alpha) fusion transcript in patients treated with all-trans retinoic acid followed by chemotherapy.

Five acute promyelocytic leukemia (APL) patients who achieved a complete remission (CR) with all-trans retinoic acid (ATRA) underwent residual disease monitoring through reverse transcription polymerase chain reaction (PCR) for PML/retinoic acid receptor-alpha (PML/RAR alpha) fusion transcript. All received consolidation chemotherapy in CR, one in the form of autologous bone marrow transplantation (ABMT). In four of the patients PCR was positive for the PML/RAR alpha transcript immediately after ATRA treatment and/or after the first consolidation chemotherapy course.

Prostaglandin E2 for prophylaxis of oral mucositis following BMT.

Between October 1988 and December 1990, 60 patients with leukaemia (25 with AML, 19 ALL and 16 CML) undergoing BMT were randomised in a double-blind clinical trial to receive prostaglandin E2 (PGE) (Prostin E2, 0.5 mg per tablet) or placebo for prophylaxis of oral mucositis. Patients had to dissolve tablets in the mouth three times daily starting 7 days before BMT and continuing until 21 days after BMT.
