Allogeneic Hematopoietic Cell Transplantation in Elderly Patients in a Latin American Country: Analysis of 11 Year of Data from the Brazilian Registry SBTMO/CIBMTR.

This study analyzed recent changes in the utilization of allogeneic hematopoietic cell transplantation (HCT) for treatment of acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and myeloproliferative diseases (MPDs) and the survival of HCT recipients ≥60 years of age in Brazil. This retrospective registry study included patients who received a first allogeneic HCT from any donor between 2012 and 2023. Of the 6657 patients, 444 (7%) were 60 years of age or older who received grafts from human leukocyte antigen (HLA)-matched related (42%) or unrelated (20%) donors or HLA-haploidentical donors (32%).

Associação Brasileira de Hematologia, Hemoterapia e Terapia Celular Consensus on genetically modified cells. III: anti-CD19 CAR-T cell therapy for patients with non-Hodgkin lymphoma.

The treatment and evolution of B-cell non-Hodgkin lymphoma (B-NHL) has undergone important changes in the last years with the emergence of targeted therapies, such as monoclonal antibodies, small molecules, antibody-drug conjugates, and bispecific antibodies. Nevertheless, a significant portion of patients remains refractory or relapsed (R/R) to the new therapeutic modalities, representing thus an unmet medical need. The use of CAR-T cells for the treatment of B-NHL patients has shown to be a promising therapy with impressive results in patients with R/R disease.

Brazilian Nutritional Consensus in Hematopoietic Stem Cell Transplantation: Adults.

The nutritional status of patients submitted to hematopoietic stem cell transplant is considered an independent risk factor, which may influence on quality of life and tolerance to the proposed treatment. The impairment of nutritional status during hematopoietic stem cell transplant occurs mainly due to the adverse effects resulting from conditioning to which the patient is subjected. Therefore, adequate nutritional evaluation and follow-up during hematopoietic stem cell transplant are essential.

Translation, Cross-Cultural Adaptation, and Validation of the Lee Chronic Graft-versus-Host Disease Symptom Scale in a Brazilian Population.

The Lee Chronic Graft-versus-Host Disease (GVHD) Symptom Scale is a patient-reported instrument developed and validated in English to measure the symptoms and functional impact of cGVHD. This tool has not yet been validated in a Latin American population, however. The Brazil-Seattle Chronic GVHD Consortium conducted a multicenter study at 5 Brazilian institutions to validate the Lee cGVHD Symptom Scale in adults with cGVHD.

Survival and graft-versus-host disease in patients receiving peripheral stem cell compared to bone marrow transplantation from HLA-matched related donor: retrospective analysis of 334 consecutive patients.

Objectives: The objective of this study was to compare the major transplant outcomes between patients receiving hematopoietic stem cell transplantation (HSCT) from bone marrow (BM) or peripheral blood stem cells (PBSC).

Methods: All consecutive HSCT patients using BM or PBSC from an HLA-matched related donors for haematological malignancies after high intensity conditioning at seven Brazilian transplant centres between January 2008 and December 2009 were retrospectively evaluated.

Results: In the study period, 334 patients were treated in the centres and included in the evaluation.

Peripheral blood stem cell yield calculated using preapheresis absolute CD34+ cell count, peripheral blood volume processed, and donor body weight accurately predicts actual yield at multiple centers.

Background: Accurate prediction of stem cell yield is important for planning leukapheresis procedures. A formula has been published (Pierelli et al., Vox Sang 2006;91:126-34) to estimate the CD34+ dose collected on the first day of leukapheresis that was based on the preapheresis peripheral blood (PB) CD34+ counts, the blood volume processed, and the donor's weight.
