Evaluation of ixabepilone efficacy and tolerability in metastatic breast cancer.

Although microtubule inhibitors are generally used in advanced stages, they provide the opportunity to prolong survival as an alternative when medical oncologists have difficulty finding options in their patients, who typically have a poor prognosis and most of whom are unresponsive to treatment. For this reason, we wanted to investigate the effect of ixabepilone treatment on survival in earlier metastatic lines. Our study also examined the frequency of side effects and survival differences in patients whose dose was reduced or whose treatment was discontinued.

Multicentral Retrospective Analysis of Venetoclax-Based Treatments in AML and MDS: A Real-World Study by the Turkish Hematology Network Group.

Acute myeloid leukemia and myelodysplastic syndrome are both clonal hematologic malignancies that primarily affect older adults. Current treatments for AML/MDS are both limited in number and efficacy. This study aims to evaluate venetoclax-based therapies in AML/MDS, focusing on overall survival and recurrence-free survival rates, and to expand real-world data on its use.

A multicenter, retrospective, observational study was conducted to explore effectiveness and safety of ixazomib plus lenalidomide with dexamethasone (IRd) in relapsed/refractory multiple myeloma (RRMM) patients following at least ≥ two lines of therapy. Patients' treatment responses, overall response rate, progression-free survival rate, and adverse events were recorded. Mean age of 54 patients was 66.

International Forum: The Turkish perspective on apheresis activity: The Turkish apheresis registry report.

Therapeutic apheresis is an extracorporeal treatment that selectively removes abnormal cells or harmful substances in the blood that are associated with or cause certain diseases. During the last decades the application of therapeutic apheresis has expanded to a broad spectrum of hematological and non-hematological diseases due to various studies on the clinical efficacy of this procedure. In this context there are more than 30 centers performing therapeutic apheresis and registered in the apheresis database in Turkey.

Methods: A multicenter, observational retrospective analysis of patients with hematological malignancies infected with COVID-19 between July 2020 and December 2021 was performed.

Therapeutic plasma exchange in gastric signet ring cell carcinoma presenting as microangiopathic hemolytic anemia: A rare case report.

Microangiopathic hemolytic anemia (MAHA) defines a group of disorders characterized by the formation of microthrombi in capillaries and arterioles and the fragmentation of erythrocytes that pass through. Cancer-related MAHA is a rare but serious condition that is encountered in patients diagnosed with a malignancy. This clinical picture is thought to be linked to certain tumor characteristics; particularly, adenocarcinoma histology, vascular invasion, and bone marrow infiltration.

Castleman Disease: A Multicenter Case Series from Turkey.

Objective: Castleman disease (CD) is a rare disease also known as angiofollicular lymph node hyperplasia. The two main histological subtypes are the hyaline vascular and plasma cell variants. It is further classified as unicentric CD (UCD) or multicentric CD (MCD) according to the anatomical distribution of the disease and the number of lymph nodes involved.

Results of multicenter registry for patients with inherited factor VII deficiency in Turkey.

Introduction: Inherited factor VII (FVII) deficiency (FVIID) is the most common of inherited rare bleeding disorders. Other determinants of clinical severity apart from FVII level (FVIIL) include genetic and environmental factors. We aimed to identify the cut-off FVIILs for general and severe bleedings in patients with FVIID by using an online national registry system including clinical, laboratory, and demographic characteristics of patients.

The Real-World Experience With Single Agent Ibrutinib in Relapsed/Refractory CLL.

Introduction/background: The emergence of novel agents targeting the B-cell receptor pathway and BCL-2 has significantly changed the therapeutic landscape of CLL. We evaluated the safety and efficacy of single-agent ibrutinib in relapsed/refractory CLL in real-world settings.

Patients/methods: A total of 200 relapsed/refractory CLL patients with a median age of 68 were included in this retrospective, multicenter, non-interventional study.

Pralatrexate experience in PTCL: A multicenter retrospective study from Turkey.

Purpose: Pralatrexate is a new generation antifolate treatment agent used for the treatment of relapsed or refractory peripheral T-cell lymphomas. This study aims to determine the general characteristics of the patients receiving pralatrexate therapy in Turkey, contributing to the literature on the effectiveness of pralatrexate therapy in peripheral T-cell lymphomas by determining the response levels of such patients to the therapy. The study also attempts to clinically examine the major side effects observed in patients during treatment with pralatrexate.

Efficacy and safety of plasmapheresis in symptomatic hyperviscosity and cast nephropathy: A Multicenter Experience in Turkey.

Background And Objectives: Cast nephropathy (CN) and hyperviscosity (HV), which we encounter in plasma cell diseases, are serious clinical manifestations that increase mortality and morbidity if not managed well in the early period. Therapeutic plasma exchange (TPE) procedures based on the removal of patient plasma is a frequently preferred treatment modality. TPE is recommended at varying levels of evidence for the treatment of CN and HV in plasma cell disorders.

A multicenter retrospective analysis on therapeutic plasma exchange in immune thrombocytopenic purpura.

Immune Thrombocytopenia (ITP) is an autoimmune disease characterized by thrombocytopenia and skin and mucosal bleeding. In patients with an indication for treatment, corticosteroids, intravenous immunoglobulin (IVIg) and anti-D are recommended as the first line, while splenectomy, thrombopoietin receptor agonists or rituximab are recommended second line options. Approximately 10 % of adult patients with ITP fall into the chronic refractory ITP group.

Background And Objectives: To consider the effectiveness of apheresis, which is a supportive treatment method, in sepsis.

Materials And Methods: A hundred and eleven adults with sepsis or septic shock were included in this retrospective study. The demographic characteristics of the patients, the focus and source of infection causing sepsis or septic shock, characteristics of the pathogen, Acute Physiological and Chronic Health Assessment (APACHE) II score, routine laboratory values, which apheresis method was used, the characteristics of the replacement fluids used during the apheresis procedure, the number of apheresis procedures, complications related to the apheresis procedure, the follow-up time after the procedure, and mortality were recorded.

Spleen Stiffness Measurement by Using Shear-Wave Elastography as a Predictor of Progression to Secondary Myelofibrosis.

Objective: Polycythemia vera (PV) and essential thrombocythemia (ET) are chronic myeloproliferative diseases that can transform to secondary myelofibrosis (SMF). In this study, we evaluated spleen stiffness using shear-wave elastography (SWE) as a predictor of progression to SMF.

Methods: Participants were grouped as healthy volunteers (HVs), PV/ET patients, and SMF patients.
