Autologous hematopoietic stem-cell transplant in small-sized and peripheral centers: a 10-year experiment.

Background: Along with continuing changes in therapeutic modalities, indications of autologous hematopoietic stem-cell transplantation (ASCT) have been emerging and changing considerably, especially in the era of targeted therapy and small molecule inhibitors. Patients treated with novel agents tend to have a longer survival period, thus eventually reaching higher ages at ASCT. Herein, and to address the question of ASCT outcomes in small, community-based, peripheral French centers, we report the 10-year follow-up results of 136 patients who received ASCT in our eight-bed ASCT unit, situated in an urban area.

Ibrutinib Treatment through Nasogastric Tube in a Comatose Patient with Central Nervous System Localization of Mantle Cell Lymphoma.

Nowadays, mantle cell lymphoma is considered to have one of the worst prognostic profiles among lymphoid malignancies. Mantle cell lymphoma rarely affects the central nervous system (CNS) as it represents about 0.9% of diagnosis and 4% among recurrent cases.

Durable Resolution of Severe Psoriasis in a Patient Treated with Pentostatin for Hairy Cell Leukemia: A Case Report.

Introduction: Pentostatin (2'-deoxycoformycin) and cladribine (2-chlorodeoxyadenosine) are adenosine analogues widely used to treat lymphoid malignancies, mainly hairy cell leukemia (HCL). Oral or parenteral adenosine analogues have been also used as immunomodulatory agents in multiple sclerosis and in acute graft-versus-host disease.

Case Report: Here, we report the case of a 43-year-old patient with a history of extensive psoriasis who later developed HCL.

Lenalidomide Maintenance Compared With Placebo in Responding Elderly Patients With Diffuse Large B-Cell Lymphoma Treated With First-Line Rituximab Plus Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone.

Purpose The standard treatment of patients with diffuse large B-cell lymphoma (DLBCL) is rituximab in combination with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). Lenalidomide, an immunomodulatory agent, has shown activity in DLBCL. This randomized phase III trial compared lenalidomide as maintenance therapy with placebo in elderly patients with DLBCL who achieved a complete response (CR) or partial response (PR) to R-CHOP induction.

Combination of ofatumumab and reduced-dose CHOP for diffuse large B-cell lymphomas in patients aged 80 years or older: an open-label, multicentre, single-arm, phase 2 trial from the LYSA group.

Background: In 2011 we reported a rituximab plus miniCHOP (reduced-dose cyclophosphamide, doxorubicin, vincristine, and prednisone) combination for patients older than 80 years with diffuse large B-cell lymphoma (DLBCL). The 2-year overall survival was 59% (95% CI 49-67) with an excess of early toxicity. To improve those results we tested the same chemotherapy protocol in combination with ofatumumab and a pre-phase treatment.

Bendamustine for the treatment of relapsed or refractory peripheral T cell lymphomas: A French retrospective multicenter study.

Peripheral T-cell lymphoma (PTCL) is a group of diseases with poor outcome and few therapeutic options. We aimed to assess the efficacy of bendamustine in real life cohort of patients.Between November 2009 and March 2015, 138 PTCL patients were treated with bendamustine in 27 centers.

Does bendamustine impact the mobilization of peripheral blood stem cells? A multicenter retrospective study of 23 cases.

Bendamustine is used in the treatment of different relapsing or refractory subtypes of lymphoma. Its impact on the yield of peripheral blood stem cells is not well known. Twenty three patients who received bendamustine followed immediately or after another chemotherapy by stem cell mobilization (SCM) were included.

Autologous hematopoietic stem cell transplantation in elderly patients (≥ 70 years) with non-Hodgkin's lymphoma: A French Society of Bone Marrow Transplantation and Cellular Therapy retrospective study.

Introduction: Limited data is available on the feasibility of high-dose chemotherapy followed by autologous hematopoietic stem cell transplantation (AHSCT) in elderly patients over 70 years of age with non-Hodgkin's lymphoma (NHL).

Materials And Methods: In the setting of the Société Française de Greffe de Moelle et de Thérapie Cellulaire (SFGM-TC) group, we retrospectively analyzed 81 consecutive patients with NHL over 70 years of age who received AHSCT.

Results: The median age at AHSCT was 72.

[The impact of donor naive and memory T cell subsets on patient outcome following allogeneic stem cell transplantation: relationship between infused donor CD4+/CCR7+ T cell subsets and acute graft-versus-host disease].

In a previous prospective study on 62 patients who underwent an HLA-matched allogeneic stem cell transplantation, we have observed that proportion of donor-derived CCR7(+)/CD4(+) T cells in the graft provided a predictive indicator of acute GVHD without interfering on chronic GVHD and relapse rate. Here we present our results on a confirmatory cohort of 137 consecutive patients. Indeed patients who received more than 76% of CCR7(+)/CD4(+) T cells in the graft developed more often acute GVHD be it of low or high grade than those who did not.

Donor-derived CD4(+)/CCR7(+) T-cell partial selective depletion does not alter acquired anti-infective immunity.

In previous studies, we observed that a high proportion of donor-derived CD4(+) T cells expressing the chemokine receptor 7 (CCR7) was a major determinant of acute GVHD, without interfering with the incidence of other post-transplant outcomes, especially relapse and nonrelapse mortality rates. Here, we investigated in vitro the impact of partially selective CD4(+)/CCR7(+) T lymphocytes on acquired anti-infective immune response in 10 donors who underwent G-CSF-primed PBSC collection. Similar quantitative and functional proliferative reactions were observed in lymphocyte cultures in the presence of adenovirus and pp65 Ags with unmanipulated and partially depleted donor samples.

Naïve subset develops the most important alloreactive response among human CD4+ T lymphocytes in human leukocyte antigen-identical related setting.

In longitudinal clinical studies, receiving a high percentage of allogeneic donor-derived CD4(+) CCR7(+) T cells, which include naïve and central memory subsets have been correlated with increased incidence and severity of acute GVHD. Whether naïve and central memory CD4(+) T-cell subsets contribute more or equally to alloimmune responses are still unclear in human. The aim of this study was to investigate in vitro the alloreactive response of purified naïve, central memory, and effector memory CD4(+) T-cell subsets in HLA identical setting.

Long-term outcome of anemic lower-risk myelodysplastic syndromes without 5q deletion refractory to or relapsing after erythropoiesis-stimulating agents.

A large proportion of lower-risk myelodysplastic syndromes (MDS) respond to erythropoiesis-stimulating agents (ESA), but most responses are transient. We updated a previously reported cohort of lower-risk MDS patients treated with ESA and analyzed outcomes after ESA failure. In 120 patients with primary resistance and 66 patients with relapse after an initial response to ESA, the 5-year cumulative incidence of acute myeloid leukemia (AML) after failure was 18.

High response rate and improved exercise capacity and quality of life with a new regimen of darbepoetin alfa with or without filgrastim in lower-risk myelodysplastic syndromes: a phase II study by the GFM.

Darbepoetin (DAR), with or without granulocyte colony-stimulating factor (G-CSF), has proved effective in treating anemia in patients with lower-risk myelodysplastic syndrome (MDS), but its effects on quality of life (QoL) and exercise functioning are less well established. In this phase II study (no. NCT00443339), lower-risk MDS patients with anemia and endogenous erythropoietin (EPO) level <500 IU/L received DAR 500 μg once every 2 weeks for 12 weeks, with G-CSF added at week 12 in non-responders.

Results from a prospective, open-label, phase II trial of bendamustine in refractory or relapsed T-cell lymphomas: the BENTLY trial.

Purpose: To determine the efficacy and safety of bendamustine as a single agent in refractory or relapsed T-cell lymphomas.

Patients And Methods: Patients with histologically confirmed peripheral T-cell lymphoma (PTCL) or cutaneous T-cell lymphoma who progressed after one or more lines of prior chemotherapy received bendamustine at 120 mg/m(2) per day on days 1 through 2 every 3 weeks for six cycles. The primary end point was overall response rate (ORR).

Daily practice management of myelodysplastic syndromes in France: data from 907 patients in a one-week cross-sectional study by the Groupe Francophone des Myelodysplasies.

Background: There is little published information on the everyday clinical management of myelodysplastic syndromes in real world practice.

Design And Methods: We conducted a cross-sectional study of all patients with myelodysplastic syndromes attending 74 French centers in a 1-week period for inpatient admission, day-hospital care or outpatient visits.

Results: Nine hundred and seven patients were included; 67.

[Polycythemia and fibromyoma. Case report].

Leiomyoma of the uterus is a frequent benign tumor of non menopausal women. Among possible complications, polycythemia is rare and often unrecognised. We report a very demonstrative case, that of a 52-year-old woman, who presented initially an episode of metrorrhagia.

[Hematopoietic growth factors and autologous or allogeneic stem cell transplantation].

Hematopoietic growth factors are usually administered in autologous and allogeneic stem cell transplantation. RhuG-CSF and rhuEPO are the most frequently used, either for mobilization of peripheral stem cells or after transplantation for the improvement of hematologic recovery. G-CSF (filgrastim or lenograstim) can be administered alone or in combination with stem cell factor to enhance stem cells mobilization.

Gene Expression in Human Acute Cutaneous and Hepatic Graft--Host Disease after Allogeneic Bone Marrow Transplantation.

Hematopoietic stem cell (HSC) allograft can be performed with cells of peripheral or medullar origin. Currently, it is the best therapy for certain malignant diseases. The curative power of allografts is based on conditioning and on the graft versus leukemia (GVL) effect.

High-dose imatinib mesylate combined with vincristine and dexamethasone (DIV regimen) as induction therapy in patients with resistant Philadelphia-positive acute lymphoblastic leukemia and lymphoid blast crisis of chronic myeloid leukemia.

Imatinib combined with high-dose chemotherapy is now becoming the gold standard for treatment of Philadelphia chromosome-positive acute leukemias. However, in all studies imatinib dosage was tapered to 400-600 mg per day. We decided to initiate a clinical trial to evaluate an opposite strategy based on high-dose imatinib (800 mg per day) combined with a less intensive chemotherapeutic regimen (vincristine and dexamethasone), which we called the DIV induction regimen.

Reduced-intensity preparative regimen and allogeneic stem cell transplantation for advanced solid tumors.

In this prospective multicenter program, we investigated allogeneic stem cell transplantation (ASCT) from HLA-identical siblings following reduced-intensity conditioning (RIC) regimen for patients with refractory metastatic solid tumors (STs). Fifty-seven patients, of whom 39 had a progressive disease (PD) at time of ASCT, received an RIC ASCT combining fludarabine, antithymocyte globulin (ATG), and busulfan. Patients were analyzed in terms of engraftment, transplant-related mortality (TRM), disease response, and outcome.
