The effects of adding decitabine to conditioning regimen for patients with acute myeloid leukemia or myelodysplastic syndrome undergoing allogeneic hematopoietic stem cell transplantation: a systematic review and meta-analysis.

Decitabine shows favorable efficacy in induction and maintenance therapy for patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), but its role in pre-transplant conditioning still has not been established. We performed a systematic review and meta-analysis of comparative studies investigating the effects of adding decitabine to conditioning regimens in AML/MDS patients undergoing allogeneic hematopoietic stem cell transplantation. Meta-analysis was conducted with Review Manager 5.4. For time-to-event outcomes, pooled hazard ratios (HRs) were calculated using generic i

Efficacy and safety of the thiotepa-busulfan conditioning regimen as for autologous stem cell transplantation in relapsed/refractory systemic diffuse large B cell lymphoma: a single-center retrospective study.

High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is a standard treatment for relapsed diffuse large B cell lymphoma (DLBCL). The BEAM regimen is widely used, but the MEAM regimen is more common in Japan due to the unavailability of carmustine. This retrospective analysis evaluated the efficacy of the thiotepa and busulfan (TT/BU) regimen compared with other regimens in 27 patients with systemic DLBCL who underwent ASCT at our institution from December 2013 to March 2022. Fourteen patients received the TT/BU regimen, while 13 received alternative regimens. The TT/B

Busulfan and thiotepa as a conditioning regimen for autologous stem cell transplantation in patients with multiple myeloma: A study of the Korean Multiple Myeloma Working Party (KMMWP-1801 study).

BackgroundAutologous stem cell transplantation (ASCT) remains the standard of care for patients with newly diagnosed multiple myeloma (MM). Several attempts to improve the efficacy of conditioning regimens have been conducted in MM, but no more effective regimen than conventional high-dose melphalan has been introduced.ObjectiveIn this study, the efficacy and toxicity of busulfan and thiotepa (BuTT) and those of high-dose melphalan (HD-MEL) were compared retrospectively as a conditioning regimen for ASCT in patients with MM.Study designIncluded in the analysis were 114 patients who received Bu

A Phase II Trial of Melphalan Based Reduced-Intensity Conditioning for Transplantation of T-Replete HLA-Haploidentical Peripheral Blood Stem Cells with Posttransplant Cyclophosphamide in Patients with Hematologic Malignancies.

T-replete haploidentical donor transplants using posttransplant cyclophosphamide (haplo) have greatly expanded donor availability and are increasingly utilized. Haplo were originally performed using truly nonmyeloablative conditioning and a bone marrow graft. We have also developed myeloablative conditioning and peripheral blood stem cell (PBSC) grafts for use with haplo. However, some patients may not tolerate myeloablative conditioning but may still benefit from a more dose-intensified preparative regimen to control malignancy and diminish graft rejection. To this end, we enrolled 25 patient

… One explanation for the high rate of relapse, as in other nonmyeloablative HSCT trials, is that the transplantation conditioning used may not be intense enough to achieve sufficient control of malignancy prior to the development of an effective graft-versus-malignancy effect. … Treatment Plan Transplantation conditioning consisted of fludarabine 30 mg/m 2 /day on days −6 to −2 and melphalan 140 mg/m 2 on day −1. On day 0, patients received an unmanipulated PBSC allograft with CD34+ dose capped at 5 × 10 6 /kg recipient. …

Second reduced intensity conditioning allogeneic transplant as a rescue strategy for acute leukaemia patients who relapse after an initial RIC allogeneic transplantation: analysis of risk factors and treatment outcomes.

Limited therapeutic options are available after relapse of acute leukaemia following first reduced intensity conditioning haematopoietic stem cell transplantation (RIC1). A retrospective study on European Society for Blood and Marrow Transplantation (EBMT) registry data was performed on 234 adult patients with acute leukaemia who received a second RIC transplantation (RIC2) from 2000 to 2012 as a salvage treatment for relapse following RIC1. At the time of RIC2, 167 patients (71.4%) had relapsed or refractory disease, 49 (20.9%) were in second CR and 18 (7.7%) in third or higher CR. With a med

Fludarabine, cyclophosphamide, anti-thymocyteglobulin, and low-dose total body irradiation conditioning enables 1-HLA-locus-mismatched hematopoietic stem cell transplantation for very severe aplastic anemia without affecting ovarian function.

Allogeneic hematopoietic stem cell transplantation for severe aplastic anemia from an alternative donor is associated with higher risks of graft rejection and severe graft-versus-host disease. We developed a conditioning regimen consisting of rabbit anti-thymocyte globulin, fludarabine, cyclophosphamide, and low-dose total body irradiation. Two adult female patients with transfusion-dependent very severe aplastic anemia underwent 1-locus mismatched transplantation using this regimen. Both patients achieved stable engraftment and the clinical course thereafter was uneventful with persistently n

Excellent outcome of allogeneic hematopoietic stem cell transplantation using a conditioning regimen with medium-dose VP-16, cyclophosphamide and total-body irradiation for adult patients with acute lymphoblastic leukemia.

We retrospectively evaluated the outcomes of 37 adult patients with acute lymphoblastic leukemia (ALL) undergoing allogeneic hematopoietic stem cell transplantation (allo-SCT) conditioned with medium-dose VP-16 (VP, 30 mg/kg), cyclophosphamide (CY, 120 mg/kg), and fractionated total-body irradiation (TBI, 12 Gy) (medium-dose VP/CY/TBI). The median age of the patients was 26 years. Thirteen patients underwent transplantation from HLA-matched related donors (MRD), 18 patients underwent transplantation from HLA-matched unrelated donors (MUD), and 6 patients underwent transplantation from HLA-mism

Fludarabine, cyclophosphamide and horse antithymocyte globulin conditioning regimen for allogeneic peripheral blood stem cell transplantation performed in non-HEPA filter rooms for multiply transfused patients with severe aplastic anemia.

Multiply transfused patients of severe aplastic anemia are at increased risk of graft rejection. Five such patients underwent peripheral blood stem cell transplantation from HLA-identical siblings with a fludarabine-based protocol. The conditioning consisted of fludarabine 30 mg/m(2)/day x 6 days, cyclophosphamide 60 mg/kg/day x 2 days and horse antithymocyte globulin (ATG) x 4 days. Two different ATG preparations were used: ATGAM (dose 30 mg/kg/day x 4 days) or Thymogam (dose 40 mg/kg/day x 4 days). Engraftment: median time to absolute neutrophil count (ANC) >0.5 x 10(9)/l was 11 days (range:

Allogeneic stem cell transplantation after myeloablative conditioning with fludarabine, thiotepa, and cyclophosphamide in relapsed or refractory aggressive B-cell and T-cell lymphomas: results of the prospective ASTRAL study.

While allogeneic stem cell transplantation (alloSCT) remains the only curative option for patients with relapsed T-cell lymphoma, its place in the treatment algorithm of aggressive B-cell lymphoma is changing. This multicentre, prospective, investigator-initiated trial investigated the efficacy and toxicity of a myeloablative conditioning regimen comprising fludarabine, thiotepa, and cyclophosphamide (FTC) prior to alloSCT in patients with relapsed/refractory (r/r) aggressive B-cell or T-cell lymphoma. Among 60 patients, PFS at one and two years was 40% (95% CI 28-52) and 36% (95% CI 24-49), O

The application of rituximab during the conditioning regimen prevents Epstein - Barr virus infection following rATG-based haploidentical hematopoietic stem cell transplantation in the era of letermovir for cytomegalovirus prophylaxis.

BACKGROUND: In the era of letermovir for cytomegalovirus (CMV) prophylaxis, several centers reported that the incidence of Epstein-Barr virus (EBV) infection were significantly increased. OBJECTIVE: To investigate the efficacy and safety of rituximab administration during conditioning regimen following haploidentical hematopoietic stem cell transplantation(haplo-HSCT)in the prevention of post-transplant EBV infection. METHODS: We conducted a retrospective analysis of 100 patients with acute leukemia or myelodysplastic syndrome who underwent haplo-HSCT. Patients in observation group(R group)

Age- and comorbidity-adjusted busulfan, fludarabine, cytarabine, and low-dose TBI-based conditioning regimen is effective for myelodysplastic syndromes with excess blasts undergoing allogeneic peripheral blood stem cell transplantation.

The optimal intensity of conditioning regimens for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients diagnosed with myelodysplastic syndromes with excess blasts (MDS-EB) remains debated. We retrospectively analyzed the clinical outcomes of 102 MDS-EB patients who received an individualized conditioning protocol based on age and comorbidity, including busulfan, fludarabine, cytarabine, and low-dose total body irradiation (TBI). All patients achieved successful engraftment, with a median time to neutrophil and platelet engraftment of 12 and 13 days, respectively. The cum

Efficacy and safety of cladribine in combination with busulfan and cyclophosphamide as an intensive conditioning regimen preceding allogeneic hematopoietic stem cell transplantation in relapsed or refractory acute myeloid leukemia.

BACKGROUND: Cladribine, an analogue of deoxyadenosine, is used for therapy of hematological malignancies. Cladribine-containing regimen has been recommended as a rescue therapy for relapsed or refractory (R/R) acute myeloid leukemia (AML). Its combination with busulfan plus cyclophosphamide (BuCy), as an intensive conditioning regimen prior to allogeneic hematopoietic stem cell transplantation (allo-HSCT), requires more clinical evidence. This study aimed to explore the efficacy and safety of cladribine plus BuCy administered as an intensive conditioning regimen before allo-HSCT in R/R AML pat

A uniform conditioning regimen of busulfan, fludarabine, and antithymocyte globulin for allogeneic haematopoietic cell transplantation from haploidentical family, matched sibling, or unrelated donors-A single-centre, prospective, explorative study.

In a prospective, explorative study, the donor-source difference of haploidentical family (HF), matched sibling (MS), and unrelated donors (UD) was evaluated for the outcome of haematopoietic cell transplantations (HCT) in 101 patients with acute myeloid leukaemia (AML) in complete remission (CR). To eliminate compounding effects, a uniform conditioning regimen containing antithymocyte globulin (ATG) was used. After transplantation, there was a significantly higher cumulative incidence of acute graft-versus-host disease (GVHD) in HF-HCT patients (49%, 7%, and 16% for HF-, MS- and UD-HCT respec

[Clinical Efficacy of Modified BU/CY as Conditioning Regimen Combined with Autologous Peripheral Blood Hematopoietic Stem Cell Transplantation in Young Acute Myeloid Leukemia Patients with Low or Intermediate Risk].

OBJECTIVE: To investigate the safety and efficacy of autologous peripheral blood hematopoietic stem cell transplantation (auto-PBHSCT) using modified BU/CY conditioning regimen for young AML patients of low and middle risk in the first complete remission (CR1). METHODS: Ten young AML patients of low and middle risk who did not want to accept allogeneic hematopoietic stem cell transplantation（allo-HSCT）and underwent auto-PBHSCT in CR1 during May 2013 to December 2016 were retrospectively analyzed. From 3 months after auto-PBHSCT, the maintenance therapy with interleukin-2 (IL-2) or IL-2 combin

The Association of Combined GSTM1 and CYP2C9 Genotype Status with the Occurrence of Hemorrhagic Cystitis in Pediatric Patients Receiving Myeloablative Conditioning Regimen Prior to Allogeneic Hematopoietic Stem Cell Transplantation.

Hemorrhagic cystitis (HC) is one of the complications of busulfan-cyclophosphamide (BU-CY) conditioning regimen during allogeneic hematopoietic stem cell transplantation (HSCT) in children. Identifying children at high risk of developing HC in a HSCT setting could facilitate the evaluation and implementation of effective prophylactic measures. In this retrospective analysis genotyping of selected candidate gene variants was performed in 72 children and plasma Sulfolane (Su, water soluble metabolite of BU) levels were measured in 39 children following treatment with BU-CY regimen. The cytotoxic

Faecal Transplantation for Ulcerative Colitis From Diet Conditioned Donors Followed by Dietary Intervention Results in Favourable Gut Microbial Profile Compared to Faecal Transplantation Alone.

BACKGROUND AND AIMS: Several faecal microbial transplantation [FMT] approaches for ulcerative colitis [UC] have been investigated with conflicting results. We have recently published the clinical outcomes from the CRAFT UC Trial using FMT with the UC Exclusion Diet [UCED], compared with FMT alone. Here we aimed to compare the two FMT strategies in terms of microbial profile and function. METHODS: Subjects recruited to the CRAFT UC study with available pre- and post-intervention faecal samples were included. Donors received diet conditioning for 14 days based on the UCED principles. Group 1 re

ISHLT consensus document on lung transplantation in patients with connective tissue disease: Part III: Pharmacology, medical and surgical management of post-transplant extrapulmonary conditions statements.

Patients with connective tissues disease (CTD) are often on immunomodulatory agents before lung transplantation (LTx). Till now, there's no consensus on the safety of using these agents perioperative and post-transplant. The International Society for Heart and Lung Transplantation-supported consensus document on LTx in patients with CTD addresses the risk and contraindications of perioperative and post-transplant management of the biologic disease-modifying antirheumatic drugs (bDMARD), kinase inhibitor DMARD, and biologic agents used for LTx candidates with underlying CTD, and the recommendat

Decitabine combined with reduced-intensity conditioning for older patients with acute myeloid leukemia in composite complete remission undergoing allogeneic hematopoietic stem cell transplantation: a multicenter, single-arm, phase 2 trial.

BACKGROUND: Outcomes of older patients with acute myeloid leukemia (AML) undergoing allogeneic hematopoietic stem-cell transplantation (allo-HSCT) remain unsatisfactory. The primary objective of this trial was to establish whether decitabine combined with reduced-intensity conditioning (RIC) regimen could improve overall survival (OS) for this population in composite complete remission (CRc). METHODS: We conducted a single-arm, phase 2 trial at six hospitals in China. Eligible patients were aged 60-80 years, had a diagnosis of AML, achieved CRc at transplantation, were willing to undergo the
