Mismatched unrelated donors allogeneic hematopoietic stem cell transplantation with antithymocyte globulin for hematological malignancies: a multicenter retrospective study in China.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) utilizing mismatched unrelated donors (MMUD) present a vital option for patients with hematologic malignancies without human leukocyte antigen (HLA)-matched donors. This multicenter retrospective study encompassed 211 adults with hematological malignancies receiving allo-HSCT with antithymocyte globulin (ATG) from ≥1 HLA locus MMUD. The findings revealed cumulative incidences of II-IV acute graft-versus-host disease (GVHD) at 180 days at 26.

Invasive Fungal Rhinosinusitis Due to Co-infection with Mucormycosis and in a Patient with Acute Lymphoblastic Leukemia.

Invasive fungal infections remain an important cause of complication and morbidity in the management of acute leukemias. Here we report the case of a 27-year-old patient from French Polynesia who was diagnosed with Philadelphia chromosome-negative B-cell acute lymphoblastic leukemia. After induction chemotherapy, she developed rhinosinusitis with extensive bone lysis.

Prognostic impact of early minimal residual disease combined with complete molecular evaluation in acute myeloid leukemia with mutated : a single center study.

We evaluated prognostic factors in 83 intensively treated adult patients with mutated AML. Targeted next-generation sequencing revealed high frequency of co-mutations in epigenetic modifiers or proliferation pathways. minimal residual disease (MRD), assessed in bone marrow by specific polymerase chain reaction after one chemotherapy course, was >0.

[Analysing pathogenic bacterial spectrum and drug resistance of bloodstream infection in patients with allogeneic hematopoietic stem cell transplantation].

To elucidate the clinical characteristics of bloodstream infection in patients with allogeneic hematopoietic stem cell transplantation (allo-HSCT) in our hospital and improves the survival of transplant patients with bloodstream infection. Two hundred and ten patients with allo-HSCT from the Department of Hematology were retrospectively analyzed between October 2014 and September 2019. Pathogen distribution, drug resistance, risk factors, and outcomes were investigated in 49 allo-HSCT patients with bloodstream infections.

Stable pulmonary function after haploidentical stem cell transplantation with post-transplant cyclophosphamide: a single center experience.

Prior studies have reported pulmonary function tests (PFT) before and after related and unrelated allogeneic hematopoietic stem cell transplantation (HSCT). However, limited data exist on the evaluation of lung function after haploidentical stem cell transplantation (HAPLO) with post-transplant cyclophosphamide (PTCY). We retrospectively reported the evaluation of PFTs at screening before HAPLO in 80 patients at 100 days and 1 year of follow-up.

Clinical Relevance of ABCB1, ABCG2, and ABCC2 Gene Polymorphisms in Chronic Myeloid Leukemia Patients Treated With Nilotinib.

Tyrosine kinase inhibitors (TKIs) have radically changed the outcome of chronic myeloid leukemia (CML) patients in the last 20 years. Moreover, the advent of second generation TKIs, namely nilotinib and dasatinib, have largely increased the number of CML patients achieving deep and sustained molecular responses. However, the possible mechanisms capable of influencing the maintenance of the long-term molecular response are not yet fully known and understood.

Multiple Myeloma Outpatient Transplant Program in the Era of Novel Agents: State-of-the-Art.

Multiple myeloma (MM) is the most common indication for autologous stem cell transplantation (ASCT), and outpatient models have been widely developed in this setting. Although numerous studies have demonstrated the safety and feasibility of outpatient ASCT, it is not a routine procedure. Stringent guidelines for patient selection and clinical management, including functional status, caregiver support, and psychological aspects, are essential to identify eligible patients.

Thiotepa-busulfan-fludarabine as a conditioning regimen for patients with myelofibrosis undergoing allogeneic hematopoietic transplantation: a single center experience.

We assessed the outcomes associated with thiotepa, busulfan and fludarabine (TBF) conditioning regimen in a cohort of 29 consecutive patients allografted for myelofibrosis (MF). The median age was 56 (range 42-70) years. According to the refined Dynamic International Prognostic Scoring System (DIPSS-plus), 15 (52%) patients were classified as high risk.

ABVD vs BEACOPP escalated in advanced-stage Hodgkin's lymphoma: Results from a multicenter European study.

The optimal first-line treatment for advanced-stage Hodgkin's lymphoma (HL) is still a matter of debate. While ABVD is less toxic and as effective as other, more intensive chemotherapy regimens, escalated BEACOPP (BEACOPPesc) is superior to ABVD for initial disease control and prolonged time-to-relapse. However, this advantage is associated with higher rate of early and late toxicities.

Consolidation radiotherapy following positron emission tomography complete response in early-stage Hodgkin lymphoma: a meta-analysis.

Despite a number of randomized trials, there is clinical equipoise whether de-escalation with the omission of radiotherapy (RT) in positron emission tomography (PET) responders is safe in early-stage Hodgkin lymphoma (HL). A comprehensive Medline and conference abstracts search was performed to identify prospective studies with the following criteria: early-stage (stage I/II) HL treated with anthracycline-based chemotherapy with PET-directed randomization to ± consolidation RT. Four studies were meta-analyzed with a total of 2267 patients (RT:  = 1136, no RT:  = 1131).

Second cancers in MPN: Survival analysis from an international study.

One out of ten patients with Philadelphia-negative myeloproliferative neoplasms (MPN) develop a second cancer (SC): in such patients we aimed at assessing the survival impact of SC itself and of MPN-specific therapies. Data were therefore extracted from an international nested case-control study, recruiting 798 patients with SC diagnosed concurrently or after the MPN. Overall, 2995 person-years (PYs) were accumulated and mortality rate (MR) since SC diagnosis was 5.

Adding hydroxyurea in combination with ruxolitinib improves clinical responses in hyperproliferative forms of myelofibrosis.

Ruxolitinib, an orally bioavailable and selective inhibitor of Janus kinase 1 (JAK1) and JAK2, significantly reduces splenomegaly and disease-related symptoms in patients with myelofibrosis (MF). However, no clear survival benefit has been demonstrated, which may in part reflect suboptimal drug exposure related to lower dosages needed to minimize hematological toxicity, specifically cytopenias. Furthermore, the optimal management of specific conditions such as leukocytosis or thrombocytosis in patients under ruxolitinib therapy is still undefined.

Genetic profiling in acute myeloid leukemia: a path to predicting treatment outcome.

Despite substantial progresses in acute myeloid leukemia (AML) diagnosis and treatment, at least half of patient will eventually die for the disease. In the last decades, the use of genetic and genomic approaches allowed the identification of patients with higher risk of recurrence after and/or resistance to CHT. However, though many novel drugs have been proposed and tested, only little clinical improvements have been made concerning the treatment of the so called 'high risk' patients.

Incidence, Survival, and Risk Factors for Adults with Acute Myeloid Leukemia Not Otherwise Specified and Acute Myeloid Leukemia with Recurrent Genetic Abnormalities: Analysis of the Surveillance, Epidemiology, and End Results (SEER) Database, 2001-2013.

Background/aim: As the knowledgebase of acute myeloid leukemia (AML) has grown, classification systems have moved to incorporate these new findings.

Methods: We assessed 32,941 patients with AML whose records are contained in the Surveillance, Epidemiology, and End Results (SEER) database.

Results: Half of all patients diagnosed between 2001 and 2013 did not have a World Health Organization (WHO) classification.

MTHFR, TS and XRCC1 genetic variants may affect survival in patients with myelodysplastic syndromes treated with supportive care or azacitidine.

We evaluated the impact of genomic polymorphisms in folate-metabolizing, DNA synthesis and DNA repair enzymes on the clinical outcome of 108 patients with myelodysplastic syndromes (MDS) receiving best supportive care (BSC) or azacitidine. A statistically significant association between methylenetetrahydrofolate reductase (MTHFR) 677T/T, thymidylate synthase (TS) 5'-untranslated region (UTR) 3RG, TS 3'-UTR -6 bp/-6 bp, XRCC1 399G/G genotypes and short survival was found in patients receiving BSC by multivariate analysis (P<0.001; P=0.

Low-dose lenalidomide plus cytarabine in very elderly, unfit acute myeloid leukemia patients: Final result of a phase II study.

Outcome for elderly patients with acute myeloid leukemia (AML) is extremely poor. Intensive induction chemotherapy is often unsuitable. Sixty-six newly diagnosed AML patients (median age: 76years), ineligible for standard therapy, were consecutively treated with low-dose lenalidomide (10mg/day orally, days 1-21) plus 10mg/m low-dose cytarabine, subcutaneously, twice a day (days 1-15) every six weeks, up to 6 cycles.

Persistent Immune Stimulation Exacerbates Genetically Driven Myeloproliferative Disorders via Stromal Remodeling.

Systemic immune stimulation has been associated with increased risk of myeloid malignancies, but the pathogenic link is unknown. We demonstrate in animal models that experimental systemic immune activation alters the bone marrow stromal microenvironment, disarranging extracellular matrix (ECM) microarchitecture, with downregulation of secreted protein acidic and rich in cysteine (SPARC) and collagen-I and induction of complement activation. These changes were accompanied by a decrease in Treg frequency and by an increase in activated effector T cells.

Managing chronic myeloid leukaemia in the elderly with intermittent imatinib treatment.

The aim of this study was to investigate the effects of a non-standard, intermittent imatinib treatment in elderly patients with Philadelphia-positive chronic myeloid leukaemia and to answer the question on which dose should be used once a stable optimal response has been achieved. Seventy-six patients aged ⩾65 years in optimal and stable response with ⩾2 years of standard imatinib treatment were enrolled in a study testing a regimen of intermittent imatinib (INTERIM; 1-month on and 1-month off). With a minimum follow-up of 6 years, 16/76 patients (21%) have lost complete cytogenetic response (CCyR) and major molecular response (MMR), and 16 patients (21%) have lost MMR only.
