Long-Term Outcomes of Childhood Acute Lymphocytic Leukemia Treated with Adapted Berlin-Frankfurt-Münster (BFM) Protocols: A Multicentric Analysis from a Developing Country.

Introduction: The objective of the current study was to determine the survival probabilities of children and adolescents with acute lymphocytic leukemia treated with adapted Berlin-Frankfurt-Münster (BFM) protocols and compare our results with the original BFM reports.

Methods: This retrospective study included 695 patients up to 19 years old treated with adapted BFM protocols between 1997 and 2018 in four hospitals in Rio de Janeiro. The 1997-2007 and 2008-2018 cohorts were analyzed separately.

Intensive salvage chemotherapy with VDTPACE or mCBAD followed by hematopoietic stem-cell support for refractory/relapsed multiple myeloma.

Introduction: Triple- and quad-refractory multiple myeloma patients usually have an aggressive course and a poor prognosis. Available therapeutic options are scarce.

Methods: The objective of the current study was to evaluate responses and toxicities of VDTPACE or mCBAD with hematopoietic stem-cell support as a bridge to subsequent therapies in patients with refractory/relapsed multiple myeloma.

Myeloablative or reduced-intensity/non-myeloablative hematopoietic cell transplantation for Philadelphia-positive acute lymphoblastic leukemia in adults older than 40 years old - a secondary analysis of a CIBMTR database.

Few studies have addressed the role of reduced-intensity conditioning (RIC) and non-myeloablative (NMA) regimens in older adults with Philadelphia acute lymphoblastic leukemia (Ph + ALL). The objective of this current study was to compare the outcomes of RIC/NMA versus TBI-based myeloablative (MAC) regimens in Ph + ALL patients older than 40 years old who underwent hematopoietic cell transplantation (HCT) in CR1. We used a freely available database from the CIBMTR.

Posttransplant cyclophosphamide beyond haploidentical transplantation.

Posttransplant cyclophosphamide (PTCy) has practically revolutionized haploidentical (Haplo) hematopoietic cell transplantation (HCT). Comparisons between Haplo with PTCy and unrelated donor (URD) with conventional graft-versus-host disease (GVHD) prophylaxis have shown comparable overall survival with lower incidences of GVHD with Haplo/PTCy and led to the following question: is it PTCy so good that can be successfully incorporated into matched related donor (MRD) and URD HCT? In this review, we discuss other ways of doing PTCy, PTCy in peripheral blood haploidentical transplants, PTCy in the context of matched related and matched unrelated donors, PTCy with mismatched unrelated donors, and PTCy following checkpoint inhibitor treatment. PTCy is emerging as a new standard GVHD prophylaxis in haploidentical, HLA-matched, and -mismatched HCT.

Total marrow irradiation in hematopoietic stem cell transplantation for hematologic malignancies.

Total body irradiation (TBI) has been an essential component of the conditioning regimen in hematopoietic cell transplantation for many years. However, higher doses of TBI reduce disease relapse at the expense of more significant toxicities. Therefore, total marrow irradiation and total marrow and lymphoid irradiation have been developed to deliver organ-sparing targeted radiotherapy.

Molecular profile of patients with myelofibrosis: a 10-year experience.

Objective: To analyze the karyotype test and myeloid panel with next-generation sequencing findings in patients with myelofibrosis, and to compare transplant characteristics in patients referred for bone marrow transplantation.

Methods: Retrospective, single-center study with patients diagnosed with myelofibrosis treated at Hospital Israelita Albert Einstein between 2010 and 2020.

Results: A total of 104 patients with myelofibrosis were examined.

ATG in HLA-Matched, Peripheral Blood, Hematopoietic Cell Transplantation in Acute Myeloid Leukemia and Myelodysplastic Syndrome: A Secondary Analysis of a CIBMTR Database.

w?>Peripheral blood stem cells (PBSC) are the preferred grafts for hematopoietic cell transplantation (HCT), according to the CIBMTR. Donor recovery is faster with PBSC harvest, but PBSC is associated with higher chronic graft-versus-host disease (GVHD) and poorer quality of life. Anti-T-cell globulin (ATG) is polyclonal IgG from rabbits or horses immunized with human thymocytes or a human T-cell line, which may reduce GVHD in HCT and improve outcomes.

Costs of matched-sibling, unrelated, and haploidentical hematopoietic cell transplantation and risk factors for greater financial burden - a Brazilian FACT-accredited single-center analysis.

The complexity and costs of hematopoietic cell transplantation (HCT) have increased over the last decades with the popularization of unrelated donor (URD) transplantation and the introduction of haploidentical transplantation with posttransplant cyclophosphamide. Few studies have addressed this issue. The objective of this study was to analyze HCT costs in a single FACT-accredited private non-profit hospital.

Risk factors for adverse outcomes following haploidentical hematopoietic cell transplantation with posttransplant cyclophosphamide: a two-center analysis.

Allogeneic hematopoietic cell transplantation (HCT) is a potentially curative therapy for several malignant hematologic diseases and alternative donors, including haploidentical, play a significant role in HCT. Despite the increasing use of haplo-HCT with PTCy, some questions remain open. The objective of the present study was to investigate risk factors for adverse outcomes after haplo-HCT with PTCy.

Lower levels of cyclosporine between days 0 and +21 may reduce later relapses without increasing graft-versus-host disease in children and adolescents with acute lymphoblastic leukemia who undergo myeloablative TBI-based allogeneic hematopoietic cell transplantation.

Background: The degree of immunosuppression required for adequate graft-versus-host disease (GVHD) prevention, while keeping an adequate graft-versus-leukemia effect, in children with acute leukemia has not been established. We report the results of a retrospective comparison of cyclosporine levels and relapse rate in children and adolescents with acute lymphoblastic leukemia (ALL).

Methods: Patients <21 y/o with ALL in remission who underwent TBI-based hematopoietic cell transplantation from related or unrelated donors between 2008 and 2021 were included.

Outcomes after Haploidentical Hematopoietic Cell Transplantation with Post-Transplantation Cyclophosphamide: A Systematic Review and Meta-Analysis Comparing Myeloablative with Reduced-Intensity Conditioning Regimens and Bone Marrow with Peripheral Blood Stem Cell Grafts.

Haploidentical hematopoietic cell transplantation (haplo-HCT) with post-transplantation cyclophosphamide (PTCy) may be the sole available curative option for several hematologic malignancies. However, the best choice of conditioning regimen and graft source has not been established. This study was conducted to compare myeloablative conditioning (MAC) regimens with reduced-intensity conditioning (RIC) regimens and peripheral blood stem cell (PBSC) grafts with bone marrow (BM) grafts in the haplo-HCT setting with PTCy.

Clinical impact of multiple DNA virus infections in nondepleted haploidentical and unrelated allogeneic hematopoietic stem cell transplantation.

Few studies have compared the clinical impact of multiple DNA-virus infections in haploidentical hematopoietic stem cell transplantation (haplo-HSCT) with posttransplant cyclophosphamide (PTCy) and unrelated donor allogeneic hematopoietic stem cell transplantation (UD-HSCT) with thymoglobulin, so we retrospectively analyzed viral infections in the first 6 mo posttransplant in these scenarios. Fifty-nine patients underwent to haplo-HSCT, and 68 to UD-HSCT. The most frequent infection was cytomegalovirus (CMV) (76.

Treatment of relapsed/refractory multiple myeloma in the bortezomib and lenalidomide era: a systematic review and network meta-analysis.

Multiple myeloma (MM) is an incurable disease, and patients usually receive multiple lines of therapy. Due to the abundance of novel treatments for MM, we conducted a network meta-analysis to identify combinations that could fare better than others in relapsed/refractory MM, in the setting of novel drugs. We searched PubMed and Cochrane databases for phase III trials in previously treated MM that had lenalidomide or bortezomib in the control arm.

Impact of CD34 Cell Dose and Conditioning Regimen on Outcomes after Haploidentical Donor Hematopoietic Stem Cell Transplantation with Post-Transplantation Cyclophosphamide for Relapsed/Refractory Severe Aplastic Anemia.

Severe aplastic anemia (SAA) is a life-threatening disease that can be cured with allogeneic cell transplantation (HCT). Haploidentical donor transplantation with post-transplantation cyclophosphamide (haplo-PTCy) is an option for patients lacking an HLA-matched donor. We analyzed 87 patients who underwent haplo-PTCy between 2010 and 2019.

Hematopoietic cell transplantation in pediatric patients with acute leukemias or myelodysplastic syndrome using unrelated adult or umbilical cord blood donors in Brazil.

The choice of alternative donors for HCT for patients without an HLA-matched related donor depends on several factors. We compared major HCT outcomes in 212 consecutive children transplanted at 11 centers in Brazil for acute leukemia or MDS from an HLA-matched unrelated donor (MUD, n = 95), mismatched unrelated donor (MMUD, n = 47) or unrelated umbilical cord blood (UCB, n = 70). Most had ALL (61%), bone marrow (57%) as the graft source and 95% received a MAC regimen.

Impact of Anti-CMV IgG Titers and CD34 Count Prior to Hematopoietic Stem Cell Transplantation from Alternative Donors on CMV reactivation.

Cytomegalovirus (CMV) reactivation remains one of the main infectious complications following hematopoietic stem cell transplantation (HSCT). In this study, we explored the role of anti-CMV antibody titers in HSCT from alternative donors and to compare the risk of CMV reactivation between posttransplant cyclophosphamide-based haploidentical HSCT and antithymocyte globulin-based unrelated donor (URD) HSCT. We included 98 CMV-positive patients, 30 undergoing haploidentical HSCT and 68 undergoing URD HSCT.

Outcomes after Haploidentical Stem Cell Transplantation with Post-Transplantation Cyclophosphamide in Patients with Primary Immunodeficiency Diseases.

Allogeneic hematopoietic stem cell transplantation (HCT) can cure primary immunodeficiency diseases (PID). When a HLA-matched donor is not available, a haploidentical family donor may be considered. The use of T cell-replete haploidentical HCT with post-transplantation cyclophosphamide (haplo-PTCy) in children with PID has been reported in few case series.

A Case Series of Post-Transplantation Cyclophosphamide in Unrelated Donor Hematopoietic Cell Transplantation for Aplastic Anemia.

Patients with severe aplastic anemia (SAA) who fail immunosuppressive therapy have a dismal prognosis. Hematopoietic stem cell transplantation (HSCT) from an unrelated donor (URD) is one of the most effective treatment options. Two institutions have independently adopted a post-transplantation cyclophosphamide (PTCy) approach for patients with SAA undergoing HSCT from a URD.

Haploidentical Transplantation with Post-Transplant Cyclophosphamide versus Unrelated Donor Hematopoietic Stem Cell Transplantation: A Systematic Review and Meta-Analysis.

Hematopoietic stem cell transplantation (HSCT) is the standard treatment for patients with high-risk hematologic malignancies. Only approximately 25% of siblings are HLA-matched, and thus alternative donors-unrelated or haploidentical-are usually the only options available. This meta-analysis aimed to compare haploidentical HSCT with post-transplantation cyclophosphamide and unrelated donor (URD) HSCT.

Comparative analysis of the pressure profilometry of vesicocutaneous continent catheterizable conduits between patients with and without rectus abdominis neosphincter (Yachia principle).

Aims: To assess whether crossing rectus abdominis muscle strips, as proposed by Yachia, would change urinary catheterizable conduit's pressure profilometry, in static and dynamic conditions.

Methods: Non-randomized selection of 20 continent patients that underwent Macedo's ileum-based reservoir, 10 including Yachia's technique (Study Group) and 10 without this mechanism of continence (Control Group). Demographics and cystometric data were assessed.
