Busulfan or Treosulfan Conditioning Platform for Allogeneic Stem Cell Transplantation in Patients Aged >60 Y With Acute Myeloid Leukemia/Myelodysplastic Syndrome: A Subanalysis of the GITMO AlloEld Study.

Unlabelled: The conditioning regimens with different alkylators at different doses can influence the outcome of allogeneic stem cell transplantation (SCT), but conclusive data are missing.

Methods: With the aim to analyze real-life allogeneic SCTs performed in Italy between 2006 and 2017 in elderly patients (aged >60 y) with acute myeloid leukemia or myelodysplastic syndrome, we collected 780 first transplants data. For analysis purposes, patients were grouped according to the type of alkylator included in the conditioning (busulfan [BU]-based; n = 618; 79%; treosulfan [TREO]-based; n=162; 21%).

Mixed T cell CHIMERISM in bone marrow at day+30 after allogeneic stem cell transplantation: Correlation with acute GVHD grades III-IV and no impact on relapse and overall survival.

Objectives: Early chimerism analysis is important to assess engraftment in allogeneic hematopoietic stem cell transplantations.

Methods: We retrospectively investigated the impact of T-cell chimerism at day 30 in bone marrow on acute graft-versus-host disease (aGVHD), relapse, and overall survival in 142 adult allo-transplanted patients.

Results: The majority of patients (89%) received myeloablative conditioning and 90% have undergone T-cell replete donor graft.

GITMO Registry Study on Allogeneic Transplantation in Patients Aged ≥60 Years from 2000 to 2017: Improvements and Criticisms.

Today, allogeneic stem cell transplantation (allo-SCT) can be offered to patients up to age 70 to 72 years and represents one of the most effective curative treatments for many hematologic malignancies. The primary objective of the study was to collect data from the allo-SCTs performed in Italy between 2000 and 2017 in patients aged ≥60 years to evaluate the changes in safety and efficacy outcomes, as well as their distribution and characteristics over time. The Italian Group for Bone Marrow Transplantation, Hematopoietic Stem Cells and Cell Therapy (GITMO) AlloEld study (ClinicalTrials.

Ibrutinib as a bridge to transplant in high-risk chronic lymphocytic leukemia: A case report and review of the literature.

The treatment landscape of chronic lymphocytic leukemia (CLL) has been challenged by the advent of novel classes of drugs, such as B-cell receptor (BCR)-inhibitors and BCL-2 antagonists. In selected high-risk patients, the choice to start allogeneic hematopoietic stem cell transplantation (alloHCT) or continue these agents is a matter of debate. Furthermore, published data about the impact on the feasibility of alloHCT and the optimal timing of administration are limited.

Safety and efficacy of granulocyte colony-stimulating factor biosimilars in engraftment after autologous stem cell transplantation for haematological malignancies: a 4-year, single institute experience with different conditioning regimens.

Background: Filgrastim biosimilars have recently been introduced into clinical practice. To date biosimilars have demonstrated comparable efficacy and safety as the originator in chemotherapy-induced neutropenia. Published experience in engraftment after autologous stem cell transplantation (ASCT) is limited and concerns relatively few patients.

A single dose of Pegfilgrastim versus daily Filgrastim to evaluate the mobilization and the engraftment of autologous peripheral hematopoietic progenitors in malignant lymphoma patients candidate for high-dose chemotherapy.

Pegfilgrastim has equivalent efficacy to daily G-CSF in enhancing neutrophil recovery after chemotherapy, but conclusive data concerning its use for peripheral blood stem cell (PBSC) mobilization are lacking. From 2003 to 2008 we used high-dose chemotherapy in 64 lymphoma patients. At mobilization chemotherapy (ESHAP) the first 26 patients used unconjugated G-CSF, while the remaining 38 patients received Pegfilgrastim.

Long-term follow-up of patients with follicular lymphoma receiving single-agent rituximab at two different schedules in trial SAKK 35/98.

Purpose: We report the long-term results of a randomized clinical trial comparing induction therapy with once per week for 4 weeks single-agent rituximab alone versus induction followed by 4 cycles of maintenance therapy every 2 months in patients with follicular lymphoma.

Patients And Methods: Patients (prior chemotherapy 138; chemotherapy-naive 64) received single-agent rituximab and if nonprogressive, were randomly assigned to no further treatment (observation) or four additional doses of rituximab given at 2-month intervals (prolonged exposure).

Results: At a median follow-up of 9.

Rituximab and subcutaneous cladribine in chronic lymphocytic leukemia for newly diagnosed and relapsed patients.

The aim of this study was to investigate the efficacy of combined treatment with rituximab and subcutaneous cladribine in patients with newly diagnosed and relapsed chronic lymphocytic leukemia (CLL). Forty-three patients with active CLL or small lymphocytic lymphoma received rituximab 375 mg/m(2) on day 1 and cladribine 0.1 mg/kg subcutaneously on days 2-6.

Rituximab in lymphocyte-predominant Hodgkin disease.

Background: Lymphocyte-predominant Hodgkin disease (LPHD) differs in biology and clinical behaviour from classic Hodgkin disease. Almost 100% of LPHD neoplastic cells express CD20 and thus rituximab could be effective; yet limited data are available.

Patients And Methods: We performed a retrospective analysis on patients with LPHD who were treated with rituximab at our institution to determine the magnitude of benefit offered by this drug.

Chronic myeloid leukemia in blast crisis treated with imatinib 600 mg: outcome of the patients alive after a 6-year follow-up.

Background: Imatinib mesylate is the first line treatment for chronic myeloid leukemia. In patients with advanced phase of the disease, the advent of imatinib significantly increased survival. However, few long-term data, based on large, prospective and controlled trials are available on the outcome of these patients.

Impact of age on the outcome of patients with chronic myeloid leukemia in late chronic phase: results of a phase II study of the GIMEMA CML Working Party.

To assess the effect of age on response and compliance to treatment in patients with chronic myeloid leukemia (CML) we performed a sub-analysis within a phase II trial of the GIMEMA CML Working Party (CML/002/STI571). Since the WHO cut-off age to define an older patient is 65 years, among the 284 patients considered, we identified 226 (80%) younger patients (below 65 years) and 58 (20%) older patients (above 65 years) before starting imatinib. Response rates (hematologic and cytogenetic) were lower in the older age group but the probabilities of progression-free survival and overall survival (median observation time 3 years) were the same.

Achieving a major molecular response at the time of a complete cytogenetic response (CCgR) predicts a better duration of CCgR in imatinib-treated chronic myeloid leukemia patients.

Purpose: Most patients with chronic-phase chronic myeloid leukemia (CML) who receive imatinib achieve a complete cytogenetic remission (CCgR) and low levels of BCR-ABL transcripts. CCgR is durable in the majority of patients but relapse occurs in a subset.

Experimental Design: To determine the potential of quantitative reverse transcription-PCR of BCR-ABL to predict cytogenetic relapse, we serially monitored residual disease in 97 CML patients with an imatinib-induced CCgR.

ABL mutations in late chronic phase chronic myeloid leukemia patients with up-front cytogenetic resistance to imatinib are associated with a greater likelihood of progression to blast crisis and shorter survival: a study by the GIMEMA Working Party on Chronic Myeloid Leukemia.

Purpose: Point mutations within the ABL kinase domain of the BCR-ABL gene have been associated with clinical resistance to imatinib mesylate in chronic myeloid leukemia (CML) patients. To shed further light on the frequency, distribution, and prognostic significance of ABL mutations, we retrospectively analyzed a homogeneous cohort of late chronic phase CML patients who showed primary cytogenetic resistance to imatinib.

Patients And Methods: Using denaturing high-performance liquid chromatography (D-HPLC) and sequencing, we screened for ABL mutations in a total of 178 bone marrow and/or peripheral blood samples from 40 late chronic phase CML patients homogeneously treated with imatinib 400 mg/d, who did not reach a major cytogenetic response at 12 months.

Imatinib and pegylated human recombinant interferon-alpha2b in early chronic-phase chronic myeloid leukemia.

Since interferon-alpha and imatinib (IM; STI571, Glivec, Gleevec) are effective for the treatment of chronic myeloid leukemia (CML), and their mechanisms of action are different, we designed an exploratory study investigating the effects of a standard IM dose (400 mg/d) and a variable pegylated interferon-alpha (PegIFN) dose (50 microg/wk, 100 microg/wk, and 150 microg/wk). The criteria for dose adjustment were designed so as to ensure the delivery of the IM dose and to protect life quality. There were 76 patients with previously untreated Philadelphia (Ph)-positive CML enrolled in the study.

High-dose therapy with autologous transplantation for aggressive non-Hodgkin's lymphoma: the Bologna experience.

Patients with aggressive non-Hodgkin's lymphoma (NHL) who relapse after initial therapy have a poor prognosis and with standard dose salvage therapy the outlook remains poor. In this work we examine the patient characteristics and outcome of patients with aggressive NHL treated with HDT and autologous transplantation at our Institute from 1982 to 1999. A retrospective analysis was performed examining patient characteristics, prior chemotherapy regimens, pretransplant disease status, HDT regimen, source of stem cells, time for hematopietic recovery, complications of transplantation, response rates, overall survival (OS) and relapse-free survival (RFS).

Molecular response to imatinib in late chronic-phase chronic myeloid leukemia.

Imatinib is a tyrosine-kinase inhibitor that binds to ABL proteins and induces cytogenetic remissions in patients with chronic myeloid leukemia (CML). In these patients measuring response by molecular techniques is clearly required. We determined the cytogenetic and molecular response (CgR, MR) to imatinib in 191 patients with late chronic-phase Philadelphia-positive (Ph+) CML, previously treated with interferon alpha.

High-dose therapy with autologous transplantation for Hodgkin's disease: the Bologna experience.

Background And Objectives: In this work we examine the characteristics and outcome of patients with Hodgkin's disease (HD) treated with high-dose therapy (HDT) and autologous transplantation at our Institute between 1982 to 2000.

Design And Methods: A retrospective analysis was performed examining patients' characteristics, prior chemotherapy regimens, pre-transplant disease status, HDT regimen, source of stem cells, time for hematopoietic recovery, complications of transplantation, response rates, overall survival (OS) and relapse-free survival (RFS).

Results: Ninety-seven patients with HD were treated and had estimated 10-year OS and RFS rates of 32% and 60%, respectively.

Risk and early cytogenetic response to imatinib and interferon in chronic myeloid leukemia.

Background And Objectives: We compared the early cytogenetic response (CgR) to a combination of imatinib mesylate (Glivec, Novartis Pharma, Basel, Switzerland) and a pegylated form of human recombinant interferon-alpha2b (pegIFN-alpha2b, PegIntron, Schering Plough, Kenilworth, New Jersey, USA) with the relative risk, either according to Sokal's or Euro scoring systems.

Design And Methods: Seventy-seven patients with early chronic phase, previously untreated, Ph-positive chronic myeloid leukemia (CML) received a combination of imatinib mesylate (400 mg/day) and pegIFN-alpha2b (3 consecutive cohorts treated with 50, 100 or 150 mg/weekly). Fifty-seven patients have completed the first 6 months of treatment and are evaluable for CgR.
