Single Apheresis Session on the 4th Day of Granulocyte Colony-Stimulating Factor Administration Seems Convenient to Collect Enough Peripheral Blood Stem Cells from Healthy Donors.

Background: To minimize adverse events of peripheral blood stem cell (PBSC) collection in healthy donors, it is reasonable to limit the total dose of granulocyte colony-stimulating factor (G-CSF) and/or the number of apheresis days without decreasing of PBSCs yield. Therefore, we have started to collect G-CSF induced PBSCs on day 4 instead of on day 5. So, we retrospectively aimed to investigate the results of this 4-day G-CSF administration.

Survival Outcomes of Patients with Primary Plasma Cell Leukemia in the Era of Proteasome Inhibitors and Immunomodulatory Agents: A Real-Life Multicenter Analysis.

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.

Lower Body Mass Index and Prognostic Nutritional Index Are Associated with Poor Posttransplant Outcomes in Lymphoma Patients Undergoing Autologous Stem Cell Transplantation.

Introduction: Pretransplant inflammatory and nutritional status has not been widely explored in terms of its impact on autologous hematopoietic stem cell transplantation (auto-HSCT) outcomes in lymphoma patients. We aimed to evaluate the impact of body mass index (BMI), prognostic nutritional index (PNI), and C-reactive protein to albumin ratio (CAR) on auto-HSCT outcomes.

Methods: We retrospectively analyzed 87 consecutive lymphoma patients who underwent their first auto-HSCT at the Adult Hematopoietic Stem Cell Transplantation Unit at Akdeniz University Hospital.

The Prognostic Impact of Pretreatment Geriatric Nutritional Risk Index in Patients with Diffuse Large B-Cell Lymphoma.

The prognostic value of the geriatric nutritional risk index (GNRI) is not clear in patients with diffuse large B-cell lymphoma (DLBCL). This study was designed to analyze the GNRI in DLBCL patients and to investigate its prognostic value in DLBCL. The archive records of DLBCL patients between 2008 and 2020 at the Akdeniz University Hospital were retrospectively analyzed.

Does hand mirror morphology a useful diagnostic tool for the treatment decision of acute undifferentiated leukemia at admission?

It is difficult how to manage acute undifferentiated leukemia in daily practice, but generally, hand mirror morphology provides ease to treat these patients. Thirty-nine years old male patient was admitted to with the complaints of echymosis, and pain at his left buttock due to an intramuscular injection for the treatment of previously diagnosed of the lower respiratory infection. Peripheral blood smear revealed >%50 blasts cells with a moderate nuclear: cytoplasmic ratio and one or more nucleoli.

Long-Term Complete Clinical and Hematological Response With Bortezomib: The Report of a Case With TEM(P)I Syndrome and a Review of the Literature.

TEMPI syndrome was first defined in 2011 and classified as a plasma cell neoplasm with associated paraneoplastic syndrome in 2016. The pathogenesis of the syndrome is not well understood. Recognition of a combination of telangiectasia, erythrocytosis with a high erythropoietin level, monoclonal gammopathy, perinephric fluid collection, and intrapulmonary shunt is the first step in managing the disease.

Outcomes of stem cell mobilization and engraftment in patients with multiple myeloma according to CD56 expression status.

Background: The molecular mechanism underlying the mobilization and engraftment of CD34+ cells is poorly understood. The most relevant factors in the regulation of stem cell release and engraftment include chemokines, adhesion molecules, and chemokine receptors. Previously, it was suggested that the absence of CD56 expression could be used as a predictive factor for mobilization failure at the time of diagnosis.

Recurrent arthritis as an unexpected side effect associated with azacitidine in a patient with myelodysplastic syndrome.

Introduction: Hypomethylating agents have confirmed efficacy for myelodysplastic syndrome and acute myeloid leukemia and are widely used. Although arthralgia is common side effect associated with hypomethylating agents, arthritis has not been reported previously.

Case Report: We present the first recorded patient with arthritis after azacitidine treatment.

Minimal Residual Disease Eradication by Azacitidine Maintenance in a Patient with Core-Binding Factor Acute Myeloid Leukemia.

Although core-binding factor AML (CBF-AML) has a favorable outcome, disease relapses occur in up to 35% of patients. Minimal residual disease (MRD) monitoring is one of the important tools to enable us to identify patients at high risk of relapse. Real-time quantitative PCR allows MRD to be measured with high sensitivity in CBF-AML.

Prognostic impact of the psoas muscle index, a parameter of sarcopenia, in patients with diffuse large B-cell lymphoma treated with rituximab-based chemoimmunotherapy.

Muscle mass, defined as the psoas muscle index (PMI), is an important parameter of sarcopenia and it has been shown to be a prognostic factor of non-hematological cancers. This study aimed to investigate the prognostic impact of sarcopenia defined using PMI measurement in patients with diffuse large B-cell lymphoma treated with R-CHOP. We retrospectively investigated the impact of pretreatment PMI on survival and response to treatment.

Comparison of Various Hematopoietic Stem Cell Mobilization Regimens in Patients with Lymphoma and Myeloma.

Background: The aim of this study was to evaluate the efficacy of cyclophosphamide-based (CB) and platinum-based (PB) chemotherapy regimens for hematopoietic stem cell mobilization in patients with Multiple Myeloma (MM), Hodgkin's lymphoma (HL), and non-Hodgkin's lymphoma (NHL) and the less well-known IEV (iphosphamide, epirubicin, etoposide) regimen in terms of stem cell harvesting competence, factors affecting stem cell com-petence, and toxicity.

Methods: A retrospective evaluation was made of 203 patients (94 MM, 37 HL, and 72 NHL) with peripheral blood stem cell mobilization in different chemotherapy regimens between 2000 and 2010 at the Department of He-matology, Faculty of Medicine, Akdeniz University.

Results: There were no differences between CB or PB mobilization regimens and IEV chemotherapy schema in terms of sufficiency of peripheral stem cell harvest, which was predefined as the collected number of peripheral stem cells ≥ 3 x 106/kg for single hematopoietic stem cell transplantation (HSCT) and ≥ 5 x 106/kg for tandem HSCT.

Investigation of seasonal frequency and pathogens in febrile neutropenia.

Background: In patients with hematological malignancies, febrile neutropenia (FEN) is the most frequent complication and the most important cause of mortality. Various risk factors have been identified for severe infection in neutropenic patients. However, to the best of our knowledge, it is not defined whether there is a change in the risk of febrile neutropenia according to seasons.

Efficacy of F-2-fluoro-2-deoxy-D-glucose Positron Emission Tomography/Computerized Tomography for Bone Marrow Infiltration Assessment in the Initial Staging of Lymphoma.

Objective: Currently F-2-fluoro-2-deoxy-D-glucose (F-FDG) positron emission tomography/computerized tomography (PET/CT) is being successfully used for staging and follow-up of Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL). Various studies have demonstrated that PET/CT effectively detects bone marrow involvement (BMI) and is concordant with bone marrow biopsy (BMB) findings, thus it is deemed as a complementary method. This study was aimed to evaluateF-FDG-PET/CT efficiency for detection of BMI in HL and NHL.

Consideration of difficulties and exit strategies in a case of face allotransplantation resulting in failure.

We describe the first rescue procedure in a case of total face allotransplantation. The recipient was a 54-year-old man with severe disfigurement of the entire face following an accidental gunshot injury 5 years previously. The large defect included the maxilla, mandible, and mid-face.

Azacitidine versus decitabine in patients with refractory anemia with excess blast-Results of multicenter study.

The present study aimed to compare the efficacy and safety of azacitidine and decitabine in patients with myelodysplastic syndrome (MDS). A total of 88 patients diagnosed with refractory anemia with excess blast (RAEB) treated with azacitidine (n=57) or decitabine (n=31) were evaluated. Comparisons between azacitidine and decitabine groups were performed in the whole cohort, and in a 1:1 propensity score-matched cohort in order to reduce the simple selection bias.

C-MYC and BCL2 translocation frequency in diffuse large B-cell lymphomas: A study of 97 patients.

Purpose: Diffuse large B-cell lymphoma (DLBCL) is an aggressive non-Hodgkin lymphoma with marked biologic heterogeneity. MYC and BCL2 rearrangements have been reported in a proportion of DLBCLs, where they may be associated with an adverse clinical outcome. The aim of this study was to determine the frequency of MYC and BCL2 translocations in DLBCL and assess the prognostic impact in DLBCL patients.

T-cell prolymphocytic leukemia presenting with leukemic serous effusion in a prostate cancer patient.

T-cell prolymphocytic leukemia (T-PLL) is highly aggressive mature postthymic lymphoproliferative disorder, which is characterized by several clinical features. Leukemic prolymphocytes are found in the peripheral blood, bone marrow, lymph nodes, spleen, liver, and sometimes skin. T-PLL and solid tumor coincidence was reported by only four previous cases.

inv (4)(p13q13) in patient with essential thrombocythemia: A case report.

The inv (4)(p13q13) cytogenetic abnormality is uncommon in hematologic malignancies. So far, it has not been previously reported in patients with essential thrombocythemia (ET). We report a first case of ET with inv (4)(p13q13) karyotype in a 69-year-old female patient who developed myelofibrosis at follow up.

Previously Unreported Chromosomal Aberrations of t(3;3)(q29;q23), t(4;11)(q21;q23), and t(11;18)(q10;q10) in a Patient with Accelerated Phase Ph+ CML.

Chronic myelogenous leukemia (CML) is a clonal hematological disorder, which is characterized by the presence of the classical or variant Philadelphia translocations. During the progression to blastic phase of the disease secondary chromosomal abnormalities may emerge. Such secondary chromosomal abnormalities are nonrandom, the more frequent ones being trisomy 8 and 19, supernumerary i(17q), and extra Philadelphia chromosomes.
