Incidence and impact of other malignancies after immunochemotherapy by fludarabine, cyclophosphamide, and rituximab as frontline treatment for chronic lymphocytic leukemia: A single-center retrospective study.

Individuals with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) have a high risk of developing other malignancies (OMs). The development of OMs may be associated with the advanced age of CLL/SLL patients, presence of a tumor-promoting microenvironment, immune alterations inherent to CLL/SLL, or chemotherapy. Importantly, the occurrence of OMs following frontline fludarabine, cyclophosphamide and rituximab (FCR) treatment is associated with a reduction in the overall survival (OS).

Unconventional T Cells Influence Clinical Outcome After Allogeneic Hematopoietic Cell Transplantation.

We evaluated the impact of early recovery of mucosal-associated invariant T cells (MAIT) and gamma-delta (γδ) T cells, especially Vδ2 T cells, on the clinical outcomes of 76 patients who underwent allogeneic hematopoietic cell transplantation (allo-HCT). MAIT cells were identified at day 20-30 post-transplant using flow cytometry and defined as CD3 TCRVα7.2CD161.

Reduced post-transplant cyclophosphamide dose with antithymocyte globulin in peripheral blood stem cell haploidentical transplantation.

Post-transplant cyclophosphamide (PT-Cy) is effective for graft-versus-host disease (GVHD) prophylaxis, but it may cause dose-dependent toxicities, particularly in frail patients. Therefore, we compared the outcomes with a reduced PT-Cy total dose (70 mg/kg) to those with the standard PT-Cy dose (100 mg/kg) in haploidentical hematopoietic cell transplantation (HCT) patients aged ≥ 65 years and those with cardiac comorbidities. All consecutive patients with a hematological malignancy receiving peripheral blood stem cells (PBSCs) after a thiotepa-based conditioning with low-dose antithymocyte globulin were included.

Reduced post-transplant cyclophosphamide doses in haploidentical hematopoietic cell transplantation for elderly patients with hematological malignancies.

Although post-transplant cyclophosphamide (PT-Cy) is effective for graft-versus-host disease (GVHD) prophylaxis, it is associated with toxicities, which might be dose-dependent. We compared the outcomes with PT-Cy at 80 mg/kg to those with PT-Cy at 100 mg/kg in elderly patients undergoing haploidentical hematopoietic cell transplantation (HCT). Inclusion criteria included peripheral blood stem cells, hematological malignancy, and age>65 years (or age>60 years if cardiac event history).

Thiotepa, busulfan and fludarabine conditioning-regimen is a promising approach for older adult patients with acute lymphoblastic leukemia treated with allogeneic stem cell transplantation.

For acute lymphoblastic leukemia (ALL) patients, total body irradiation (TBI)- based conditioning regimens are the first choice specially in young population. However, several studies have shown an equivalence in clinical outcomes with thiotepa-based conditioning regimen. We performed a retrospective study to evaluate the outcome of adult ALL patients who received allogeneic hematopoietic stem cell transplantation (allo-HCT) with a thiotepa-busulfan-fludarabine (TBF) myeloablative conditioning regimen with reduced toxicity.

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.

Photobiomodulation: a promising innovative approach for preventing oral mucositis in patients undergoing hematopoietic stem cell transplantation.

Purpose: This single-center retrospective study aims to assess the feasibility, safety, and tolerability of CareMin650, a new photobiomodulation device, for both preventing oral mucositis (OM) and reducing its severity in the setting of hematopoietic stem cell transplantation (HCT).

Methods: Patients who underwent autologous HCT for hematological malignancies between November 2020 and October 2021 could be included. Prophylactic photobiomodulation (PBM) was used daily from day 1 of conditioning until the day of neutrophil recovery at a dose of 3 J/cm.

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.

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.

Early Cardiac Toxicity Associated With Post-Transplant Cyclophosphamide in Allogeneic Stem Cell Transplantation.

Background: Post-transplant cyclophosphamide (PT-Cy) has become a standard of care in haploidentical hematopoietic stem cell transplantation (HSCT) to reduce the risk of graft-versus-host disease. However, data on cardiac events associated with PT-Cy are scarce.

Objectives: This study sought to assess the incidence and clinical features of cardiac events associated with PT-Cy.

Weak immunogenicity of SARS-CoV-2 vaccine in patients with hematologic malignancies.

This study evaluated the safety and immunogenicity of BNT162b2 vaccine in patients with hematological malignancies. Antibodies blocking spike binding to immobilized ACE-2 (NAb) correlated with anti-Spike (S) IgG d42 titers (Spearman r = 0.865, p < 0.

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.

Gemtuzumab Ozogamicin Combined With Intensive Chemotherapy in Patients With Acute Myeloid Leukemia Relapsing After Allogenic Stem Cell Transplantation.

Background: More than one-third of patients with acute myeloid leukemia (AML) will relapse after allogenic hematopoietic cell transplant (allo-HCT). The main challenge is to overcome disease resistance to achieve a new complete remission while avoiding excessive toxicity. Gemtuzumab ozogamicin (GO), a conjugate of calicheamicin linked to the humanized monoclonal anti-CD33 antibody, has been used for refractory or relapsed AML with promising response rates, but liver toxicity of GO has long been considered a limiting factor.

Extracorporeal photopheresis as first-line strategy in the treatment of acute graft-versus-host disease after hematopoietic stem cell transplantation: A single-center experience.

Background Aims: Corticosteroids are the standard first-line treatment for acute graft-versus-host disease (aGVHD), but they are associated with many complications, and less than half of patients have a sustained response.

Methods: To improve outcomes, we performed a retrospective study to analyze the efficacy of the addition of extracorporeal photopheresis (ECP) to low-dose corticosteroids in 37 adult patients (median age, 57 years) with skin-predominant aGVHD (grade I, n = 17; grade II, n = 18; and grade III, n = 2). All patients received ECP in combination with 1 mg/kg prednisone (n = 26) or topical steroids (n = 11).
