Optimal conditioning for adults with acute lymphoblastic leukemia (ALL) treated with haploidentical hematopoietic cell transplantation (haplo-HCT) and post-transplant cyclophosphamide has not been established so far. We retrospectively compared outcomes for two myeloablative regimens: fludarabine + total body irradiation (Flu-TBI, n = 117) and thio...

Allogeneic hematopoietic cell transplantation (allo-HCT) is the only curative treatment for patients with myeloid/lymphoid neoplasm (MLN) with FGFR1 rearrangement, but data on overall results are limited. We report on the largest series of patients (n = 22) with FGFR1-rearranged MLN undergoing allo-HCT. Distribution according to cytogenetic subtype...

Background Autologous haematopoietic stem cell transplantation (AHSCT) is highly effective in reducing new inflammatory activity in aggressive multiple sclerosis (MS). A remarkable decrease of serum neurofilament light chains (sNfL) concentration, a marker of axonal damage, was reported in MS following high-intensity regimen AHSCT, but hints for po...
Article
Background: Effectiveness of autologous haematopoietic stem-cell transplantation (AHSCT) in relapsing-remitting multiple sclerosis (MS) is well known, but in secondary-progressive (SP-) MS it is still controversial. Therefore, AHSCT activity was evaluated in SP-MS using low-dose immunosuppression with cyclophosphamide (Cy) as a comparative treatme...

A late presenter AIDS patient with severe T cell depletion presented non-severe COVID-19 symptoms, with prolonged viral shedding. Our case report supports the hypothesis that an effective T cell response may be dispensable for the control of COVID-19 progression to severe forms, while it may be necessary for SARS-CoV-2 clearance.

The impact of GVHD and graft-versus-leukemia effect in unrelated cord blood transplantation (UCBT) is controversial. In the Eurocord/ALWP EBMT and JSTCT/JDCHCT collaborative study, we evaluated the impact of GVHD on UCBT outcomes in Japanese and European registries. A total of 3,690 adult patients with acute leukemia who received their first single...

Introduction. The outcome of relapsed/refractory large B-cell lymphomas, not eligible or cured by high dose chemotherapy due to persistent disease, is very unsatisfactory. The introduction of anti-CD19 chimeric antigen receptor T cells (CAR-T) in this setting, showed impressive long-term results in registrative trials. Axicabtagene ciloleucel (axi-...

Given the availability and efficacy of the mobilizing agent plerixafor in augmenting hematopoietic progenitor cell mobilization with granulocyte colony-stimulating factor (G-CSF), there is a strong case for comparing the cost-effectiveness of mobilization with G-CSF + cyclophosphamide versus G-CSF alone. This study investigated the cost and effecti...

As CD34+ cell mobilization, we used, in 138 Myeloma patients, Plerixafor on-demand in association to a low dose cyclophosphamide regimen (CTX 2 gr/m2) and G-CSF. This schedule obtained a high rate of success in harvest, the failure of harvesting CD34+ > 2x10e6/Kg in a maximum of 3 aphereses was only 1.4%. In multivariable analysis, rate of successf...

Autologous haematopoietic stem cell transplantation (AHSCT) is increasingly used to treat people with multiple sclerosis (MS). Supported by an evolving evidence base, AHSCT can suppress active inflammation in the central nervous system and induce long-term changes in immune cell populations, thereby stabilizing, and, in some cases, reversing disabi...

FLT3-ITD and NPM1 mutation refine prognostic stratification in acute myeloid leukemia (AML) with intermediate-risk cytogenetics. However, data on their role in patients undergoing autologous stem cell transplantation (Auto-SCT) as post-remission therapy (PRT) are limited. We therefore sought to retrospectively evaluate the role of FLT3-ITD and NPM1...

In CD34+ cells mobilization of patients with multiple myeloma (MM), the use of Cyclophosphamide (CTX) at a dose of 2 g/m² has low efficacy although also lower toxicity. The suboptimal mobilizing effect of low-dose CTX, however, may be overcome by plerixafor (PLX) on demand. We conducted a prospective multicenter study in 138 patients with MM to eva...
Article
The use of myeloablative conditioning (MAC) in umbilical cord blood transplantation (UCBT) has been associated with high non-relapse mortality (NRM) in patients >40 years, especially those having a high HLA disparity, thus limiting wider applications. We hypothesized that the NRM advantage of reduced intensity conditioning (RIC) and higher GVL asso...

Over the last 20 years, haematopoietic stem cell transplantation (HSCT) has been used to treat patients with severe autoimmune and inflammatory diseases whose response to standard treatment options has been limited, resulting in a poor long-term prognosis in terms of survival or disability. The vast majority of patients have received autologous HSC...

Background: While intensive consolidation therapy with autologous stem cell transplantation (ASCT) can secure a remission in selected Acute Myeloid Leukemia (AML) patients with intermediate-risk cytogenetics, a substantial proportion will ultimately relapse. Knowledge of the mutational status of FMS like tyrosine kinase 3 internal tandem duplicatio...
Conference Paper
Introduction: Hematopoietic Stem Cell Transplantation (HSCT) from unrelated donors (UD) is a curative therapy for many hematologic malignancies. HLA matching plays a major role in determining HSCT outcome but the relative role of incompatibilities at the different HLA loci is still debated. In particular, over 80% of UD-HSCT are performed across HL...

Background Natalizumab (NTZ) is a highly effective treatment for relapsing‐remitting multiple sclerosis (RRMS), but its withdrawal is often followed by disease reactivation or rebound, even if other disease‐modifying treatments (DMTs) are administered. In this study, for the first time, safety and efficacy of autologous hematopoietic stem cell tran...

Background: Thiotepa-busulfan-fludarabine (TBF) is a widely used conditioning regimen in single umbilical cord blood transplantation (SUCBT). More recently, it was introduced in the setting of non-T cell depleted haploidentical stem cell transplantation (NTD-Haplo). Whether TBF based conditioning provides additional benefit in transplantation from...
