Objective: In this study, we aimed to obtain real-life data on the use of antimyeloma agents, which significantly increase overall survival (OS) in multiple myeloma (MM) patients, in primary plasma cell leukemia (pPCL) patients with poor prognosis.
Materials And Methods: Data from 53 patients who were diagnosed with pPCL between 2011 and 2020 and who used at least one proteasome inhibitor (PI) and/or immunomodulatory (IMID) agent were analyzed retrospectively. Depending on the year of the pPCL diagnosis, 20% leukocytes or ≥2x10/L plasma cells in the peripheral blood was used as a diagnostic criterion.

Introduction: Patients with leukaemia are exposed to infections as long as they are neutropenic. During this period, anorectal pathologies are among the common foci of infection with high mortality. In this study, we aim to investigate the factors that may have a predictive effect on early diagnosis and rapid intervention in perianal complications occurring in neutropenic patients diagnosed with leukaemia.

This retrospective study aimed to evaluate the effects of bone marrow (BM) fibrosis on disease prognosis and the effects of specific tyrosine-kinase inhibitors (TKIs) on BM fibrosis in CML patients.
Methods: The study included 96 patients (>18 years) diagnosed with chronic phase (CP) CML.
Background The change in hepatitis B surface antibody (anti-HBs) titers after chemotherapy (CT) in patients with hematological malignancy, affecting factors, and its clinical implications have not been sufficiently understood. Therefore, we aim to evaluate the change in anti-HBs titers and hepatitis B virus reactivation (HBVr) after CT. Methods This retrospective study enrolled patients with hematological malignancies who received CT between 2013 and 2021.

As the life expectancy of CML patients has approached that of the general population, research has shifted towards improving quality of life and economic considerations. After 2010, it was shown that some patients could maintain molecular response even after discontinuing imatinib.

The aim of this study is to determine the frequency of SPC in CLL patients and determine the relationship between these cancers and their treatment status, cytogenetic factors, and other risk factors.
Methods: The study was designed as multicenter and retroprospective.
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.

This study aims to compare the efficacy and toxicity of ATRA monotherapy and ATRA+MTX+ 6-MP combination as the maintenance treatment for 2 years in APL patients who achieved molecular complete response after induction and consolidation with ATRA+chemotherapy. A total of 71 patients from 4 different centers were included in this study.

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.

Limited studies have been published examining the blood group as an epidemiological factor that can contribute to development of TTP. It has been suggested that due to low vWF levels, the distribution of the "O" blood group among TTP patients may be lower than anticipated compared to the blood group distribution rates in the normal population.

The pathogenesis of coagulation disorders, which is seen in viral hemorrhagic fevers remains to be elucidated. Thrombin-activatable fibrinolysis inhibitor (TAFI) has a key role in this process In this study, we aimed to evaluate whether TAFI levels contributed to bleeding and whether it is related to prognosis in CCHF patients.

Lymphomatoid granulomatosis (LG) is Epstein-Barr virus associated and aggressive B cell lymphoproliferative disease. The most common sites of involvement are lungs, skin, kidneys, liver and central nervous system. The clinical presentation of pulmonary LG may mimic infectious diseases, malignancies or vasculitis.

Methods: This retrospective study included 77 patients with hematological cancer and COVID-19. Patients were sub-grouped for analysis as survivors and non-survivors.
Introduction: Imatinib is generally well tolerated by patients. The most common ophthalmic side effects are eyelid edema and periorbital edema. Other side effects which occur at rates of <1% include blepharitis, blurred vision, conjunctival hemorrhage, conjunctivitis, retinal hemorrhage, etc.

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.

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.

Ruxolitinib, a selective inhibitor of JAK 1 and 2, significantly reduces constitutional symptoms and spleen size compared with placebo, and has significant clinical benefits in patients with myelofibrosis. The most common haematological side effects are thrombocytopenia and anaemia, and the most common non-haematological side effects are grade 1-2 diarrhoea and pyrexia.

Thus, we aimed to determine the impact and safety of BV as maintenance after ASCT in real-world patients. Seventy-five patients with relapsed/refractory HL started on BV consolidation therapy after ASCT due to high risk of relapse, between January 2016 and July 2019, from 25 institutions, were included in the study.

There are only a few predictive markers that can truly aid therapy decisions in patients with acute myeloid leukemia (AML). The current study aimed to examine the impact of easily available common laboratory parameters on the course and prognosis of patients with AML. Gender, initial bone marrow blast percentage, mean platelet volume (MPV), lymphocyte-to-monocyte ratio, treatment regimen, and complete remission (CR1) were found to have a statistically significant effect on both OS and PFS ( < 0.
