Based on the impairment of erythropoietin production after allogeneic hematopoietic cell transplantation (HCT), we previously reported in a phase-2 trial that recombinant human erythropoietin (rhEPO) therapy was very efficient when started one month after transplantation. We also demonstrated that anemia after nonmyeloabalative (NM) HCT was less sensitive to rhEPO therapy than after conventional allogeneic HCT. This prompted us to confirm these findings in a prospective randomised trial. One hundred and thirty-one patients were randomised (1:1) between no treatment (arm 1) or erythropoietin (Neorecormon) at the dose of 500 U/kg/week (arm 2). Once the target Hb (13g/dL) has been attained, the dose of rhEPO was reduced by half, while it was withheld when Hb was = 14g/dL. Cohort A included 42 patients on day 28 after myeloablative HCT, cohort B 39 patients on day 28 after NMHCT, and cohort C 50 patients on day 0 of NMHCT. Primary endpoints included proportion of complete correctors (i.e. patients reaching Hb = 13g/dL) and median time to achieve Hb correction in each arm. The proportion of complete correctors before day 126 posttransplant was 0% in group 1A vs 52.4% in group 2A, 0% in group 1B vs 69.5% in group 2B and 19.1% in group 1C vs 70.2% in group 2C. Median time to achieve Hb = 13g/dL was not reached in group 1B vs 49 days in group 2B; 363 and 59 days in groups 1A and 1B respectively and 363 and 87 days in groups 3A and 3B respectively (figure 1). Hb evolution in each group is shown in figure 2. Seventyone patients (47/62 in control groups and 24/57 in treated groups, p=0.0003) required red blood cell transfusions. The difference was most pronounced in cohort B. There was no difference in rates of thrombo-embolic events or other complications between the two arms. In conclusion, this is the first trial to demonstrate that EPO therapy hastens erythroid recovery and decreases transfusion requirements when started one month after allogeneic HCT. [less ▲]

The Belgian Hematological Society (BHS) guideline panel on adult primary immune thrombocytopenia (ITP) reviewed the recent literature on diagnosis and treatment to make recommendations on the best strategies for frontline and subsequent-line treatment. No treatment is necessary for patients with platelet counts higher than 30000/ l in the absence of bleeding symptoms. Patients newly diagnosed or relapsing after a long-term treatment-free period can be managed with corticosteroids with or without intravenous immunoglobulins. A second line therapy is indicated for those patients who are intolerant or unresponsive to or relapse after initial corticosteroid treatment and have a risk of bleeding. The guideline panel recommends splenectomy as it is the treatment with the highest curative potential and an acceptable safety pro le. If possible, splenectomy should be delayed to at least twelve months after diagnosis as spontaneous remission can occur in this time period. Thrombopoietin receptor (TPO-R) agonists are recommended for patients who are refractory to or relapse after splenectomy or who have a contra-indication to splenectomy irrespective of the duration of ITP. The guideline panel agrees that rituximab, azathioprine, cyclophosphamide, cyclosporine A, danazol, dapsone, mycophenolate mofetil and vincristine/vinblastine are potential treatment options, especially for patients refractory to TPO-R agonists.

The sub-committee on lymphoproliferative disorders of the Belgian Hematological Society has met several times to prepare guidelines on the management of patients with peripheral T-cell lymphomas. Each panellist's expert provided interpretation of the evidence, based on literature review and personal experience. The available evidence was systematically discussed prior to formulating recommendations. A systematic approach to obtain consensus of expert opinion was used. After each meeting, the draft guideline was circulated to all experts for comment and approval. The present guidelines focus on general management of peripheral T-cell lymphomas with special emphasis on more specific disease-adapted stratégies. [less ▲]

Busulfan is commonly used in preparative conditioning regimens prior to hematopoietic stem cell transplantation in children and young adults for malignant and non-malignant disorders. For many years Busulfan was only available in an oral form, resulting in large inter- and intra-patients variability in plasma exposure, associated with higher graft failure rate as well as higher toxicity such as venoocclusive disease. With the development of an intravenous formulation of Busulfan, a more accurate control of both the inter- and intra-patient variability has been provided. The goal of this study was to evaluate the use and efficacy of intravenous Busulfan in comparison with the oral formulation in children undergoing an autologous transplantation after conditioning with Busulfan. Despite the small number of patients, this study confirmed the apparent benefit of intravenous Busulfan in children undergoing an autologous HSCT. The use of a 5-level dose schedule defined by body weight resulted in an efficient engraftment with marked reduction in the incidence of veno-occlusive disease compared with oral Bu. In terms of diseasefree outcome, survival and event-free survival, similar results have been obtained in both groups. The choice of this formulation of Busulfan should therefore be considered.

The Transplantation Committee of the Belgian Hematological Society (BHS) is supported by all university centers and nonuniversity centers with significant transplant activity. The committee is involved in the development of transplant guidelines and recommendations, the transplant peer review process, contacts with regulatory authorities, the introduction of expanded access and medical need programs and the initiation of academic studies addressing important questions in the transplant field. Since 2008, 8 clinical trials have been initiated after approval by the Ethics Committees and the National Competent Authority (AFMPS/FAGG). So far, one of them has been completed and is being prepared for publication. In this paper, we briefly describe the rationale, objectives, treatment arms, major inclusion criteria and current status of these different trials. In addition and for each trial a link is provided to the BHS website to obtain more details regarding inclusion criteria, participating centers and administrative/contact information [less ▲]

Follicular lymphoma is an indolent lymphoma that has occurred more frequently over the last decades. In this article we present an overview of the diagnosis and initial work-up, prognostic scoring system and choice of therapy. For limited stage disease radiotherapy is the treatment of choice, and may have a curative potential. For advanced stages treatment should be initiated upon certain criteria, and is essentially based on immunochemotherapy, rituximab plus chemotherapy. The choice of chemotherapy depends on age, frailty, and specific toxicities of chemotherapy. Maintenance therapy with rituximab after induction has become standard practice. Since virtually all patients relapse eventually, an overview of the treatment in the relapsed setting is given. The treatment is then again based on immunochemotherapy but there is also a place for radio-immunotherapy, or immunotherapy alone. For young patients, high dose chemotherapy with autologous stem cell rescue should be considered. A brief overview on novel agents, and agents that are in the pipeline, is given. We conclude with some recommendations for follow-up. [less ▲]

Reduced intensity conditioning (RIC) regimens have allowed performing allogeneic haematopoietic stem cell transplantation (HSCT) in patients for whom conventional myeloablative allogeneic HSCT is associated with unacceptable risks of non-relapse-mortality. This approac relies mainly on graft-versus-tumour effects for tumour eradication. Retrospective studies have suggested that, in patients aged 40 to 60 years, RIC-HSCT was associated with a higher risk of relapse but a lower incidence of transplant-related mortality than myeloablative allogeneic HSCT, leading to similar progression-free and overall survivals. After reviewing the rationale for RIC-HSCT, this article discusses the results of RIC-HSCT in specific deseases, and proposes what could be current indications for RIC-HSCT in 2011. Finally, the article briefly presents some possible strategies aimed at increasing the anti-tumoral activity of the procedure while reducing the incidence and severity of acute graft-versus-host disease.
