Anaemia and absolute or functional iron deficiency (ID) are common issues among cancer patients, with the prevalence of ID ranging from 32% to 60%. Most randomised clinical trials have shown superior efficacy of IV iron over oral or no iron supplementation in anaemic cancer patients receiving erythropoiesis-stimulating agents. Intravenous iron supplementation reduced blood transfusions, increased haemoglobin, and improved quality of life. At recommended doses, IV iron is well tolerated, and allergic reactions are exceedingly rare with modern formulations. Oral iron is often poorly tolerated and this can lead to compliance issues.

Purpose : To investigate the impact of prior-to-transplantation azacitidine (AZA) on patient outcome after allogeneic stem-cell transplantation (alloSCT) for myelodysplastic syndrome (MDS). Patients and Methods Of the 265 consecutive patients who underwent alloSCT for MDS between October 2005 and December 2009, 163 had received cytoreductive treatment prior to transplantation, including induction chemotherapy (ICT) alone (ICT group; n 98), AZA alone (AZA group; n 48), or AZA preceded or followed by ICT (AZA-ICT group; n 17). At diagnosis, 126 patients (77%) had an excess of marrow blasts, and 95 patients (58%) had intermediate-2 or high-risk MDS according to the International Prognostic Scoring System (IPSS). Progression to more advanced disease before alloSCT was recorded in 67 patients. Donors were sibling (n 75) or HLA-matched unrelated (10/10; n 88). They received blood (n 142) or marrow (n 21) grafts following either myeloablative (n 33) or reduced intensity (n 130) conditioning. Results : With a median follow-up of 38.7 months, 3-year outcomes in the AZA, ICT, and AZA-ICT groups were 55%, 48%, and 32% (P .07) for overall survival (OS); 42%, 44%, and 29% (P .14) for event-free survival (EFS); 40%, 37%, and 36% (P .86) for relapse; and 19%, 20%, and 35% (P .24) for nonrelapse mortality (NRM), respectively. Multivariate analysis confirmed the absence of statistical differences between the AZA and the ICT groups in terms of OS, EFS, relapse, and NRM. Conclusion : With the goal of downstaging underlying disease before alloSCT, AZA alone led to outcomes similar to those for standard ICT. [less ▲]

Background: The availability of tyrosine kinase inhibitors (TKIs) has considerably changed the management of Philadelphia chromosome positive leukemia. The BCR-ABL inhibitor imatinib is also known to inhibit the tyrosine kinase of the stem cell factor receptor, c-Kit. Nilotinib is 30 times more potent than imatinib towards BCR-ABL in vitro. Studies in healthy volunteers and patients with chronic myelogenous leukemia or gastrointestinal stromal tumors have shown that therapeutic doses of nilotinib deliver drug levels similar to those of imatinib. The aim of this study was to compare the inhibitory effects of imatinib and nilotinib on proliferation, differentiation, adhesion, migration and engraftment capacities of human cord blood CD34+ cells. Design and Methods: After a 48-hour cell culture with or without TKIs, CFC, LTC-IC, migration, adhesion and cell cycle analysis were performed. In a second time, the impact of these TKIs on engraftment was assessed in a xenotransplantation model using NOD/SCID/IL-2Rc (null) mice. <br />Results: TKIs did not affect LTC-IC frequencies despite in vitro inhibition of CFC formation due to inhibition of CD34+ cell cycle entry. Adhesion of CD34+ cells to retronectin was reduced in the presence of either imatinib or nilotinib but only at high concentrations. Migration through a SDF-1a gradient was not changed by cell culture in the presence of TKIs. Finally, bone marrow cellularity and human chimerism were not affected by daily doses of imatinib and nilotinib in a xenogenic transplantation model. No significant difference was seen between TKIs given the equivalent affinity of imatinib and nilotinib for KIT. <br />Conclusions: These data suggest that combining non-myeloablative conditioning regimen with TKIs starting the day of the transplantation could be safe.

Objectives: The aim of this study is to provide relevant and accurate information on prevalence and treatment patterns of anaemia in Belgian cancer patients. Methods The Anaemia Day 2008 survey was a single visit, multi-centre, non-interventional study in adult cancer patients under systemic therapy (chemotherapy, hormonal, immunological and/or targeted therapy) and/or radiotherapy. Efforts were made to enrol the maximum number of patients seen in each centre that day. Patients signed an informed consent and relevant data were collected from their files, i.e. disease and disease stage, cancer therapy and anti-anaemic treatment, including transfusions and the use of erythropoietin stimulating agents (ESA). A blood count of each included patient was performed. Haemoglobin (Hb) values (grams per decilitre) were classified into four categories to assess the severity of anaemia, as defined byWHO: no anaemia: Hb≥12 g/dL; mild 10≤Hb≤11.9 g/dL; moderate 8≤Hb≤9.9 g/dL; severe Hb< 8 g/dL. Univariate and multivariate analyses were carried out with anaemia as the dependent variable. Results A total of 1,403 eligible patients aged 63±13 years (mean age±SD) were enrolled in 106 oncology or haematology centres. The mean Hb level (±SD) was 11.6 g/dL (±1.8 g/dL) and the prevalence of anaemia (Hb<12 g/dL) was 55.7% (95% CI, 53.1–58.3%), respectively, 35.9% mild, 17.8% moderate and 2.1% severe anaemia. Anaemia was more frequent in females than in males, and in patients with haematological malignancies (73.4%) than in those with solid tumours (51.4%; p<0.001). Anaemia prevalence was higher in hospitalised patients (75.5%) compared to those seen in one-day-clinic (54.3%) or in consultation (33.9%; p<0.001), and in patients treated with chemotherapy (61.3%) compared to those receiving radiotherapy (34.4%) or hormonal therapy (19.5%; p<0.001). There was a clear correlation between severity of anaemia and WHO performance status (p< 0.001). Among anaemic patients, 53.1% received no treatment (mean Hb 10.8±0.9 g/dL). Among the anaemic patients who received therapy for their anaemia (mean Hb 9.7±1.1 g/dL), the most frequent treatments were RBC transfusions (42%), ESA (34.6%), transfusions+ESA (12%), ESA+iron (7.9%) and iron alone (3.5%). Comparison to the ECAS survey shows that there has been no major change in attitude towards anaemia management in the last decade. Conclusion This survey shows that cancer-related anaemia is still frequently observed in cancer patients. Even if in our study ESA were used more frequently than about 10 years ago, still a large amount of anaemic patients who could be treated for anaemia according to EORTC guidelines, were not.

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 ▲]

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.

Background: Chronic diseases reduce the availability of iron for effective erythropoiesis. This review summarises clinical consequences of iron deficiency (ID) and anaemia in cancer patients, mechanisms how impaired iron homeostasis affects diagnosis and treatment of ID, and data from clinical trials evaluating i.v. iron with or without concomitant erythropoiesis-stimulating agents (ESAs). Design: Clinical trial reports were identified in PubMed and abstracts at relevant major congresses. Results: Reported prevalence of ID in cancer patients ranges from 32 to 60% and most iron-deficient patients are also anaemic. Randomised clinical trials have shown superior efficacy of i.v. iron over oral or no iron in reducing blood transfusions, increasing haemoglobin, and improving quality of life in ESA-treated anaemic cancer patients. Furthermore, i.v. iron without additional ESA should be evaluated as potential treatment in patients with chemotherapyinduced anaemia. At recommended doses, i.v. iron is well tolerated, particularly compared with oral iron. No serious drug-related adverse effects were seen during long-term use in renal disease and no effect on tumour growth has been observed in trials with anaemic cancer patients. Conclusions: Reliable diagnosis and treatment of ID are recommended key steps in modern cancer patient management to minimise impact on quality of life and performance status. [less ▲]

Fever of unknown origin (FUO), with more than 200 potential causes, can represent a real diagnostic challenge.For the work-up of FUO, the first step is to pay attention to each element revealed by a detailed history, a complete physical examination and by some basic diagnostic tests. These elements may constitute some clues that can guide the physician for the prescription of further appropriate diagnostic examinations and procedures. If there is no real specific clues,a pet-scan seems to be useful for the work-up of FUO. [less ▲]

Aims: We here address the question of expression and role of GH/IGF axis in the thymus. Methods: Using RT-qPCR, the expression profile of various components of the somatotrope GH/IGF axis was measured in different thymic cell types and during thymus embryogenesis in Balb/c mice. Effect of GH on T-cell differentiation was explored through thymic organotypic culture. Results: Transcription of Gh, Igf1, Igf2 and their related receptors predominantly occurred in thymic epithelial cells (TEC), while a low level of Gh and Igf1r transcription was also evidenced in thymic T cells (thymocytes). Gh, Ghr, Ins2, Igf1, Igf2, and Igfr1, displayed distinct expression profiles depending on the developmental stage. The protein concentration of IGF-1 and IGF-2 were in accordance with the profile of their gene expression. In fetal thymus organ cultures (FTOC) derived from Balb/c mice, treatment with exogenous GH resulted in a significant increase of double negative CD4-CD8- T cells and CD4+ T cells, together with a decrease in double positive CD4+CD8+ T cells. These changes were inhibited by concomitant treatment with GH and GHR antagonist pegvisomant. However, GH treatment also induced a significant decrease in FTOC Gh, Ghr and Igf1 expression. Conclusion: These data show that the thymotropic properties of the somatotrope GH/IGF-1 axis involve an interaction between exogenous GH and GHR expressed by TEC. Since thymic IGF-1 is not increased by GH treatment, the effects of GH upon T-cell differentiation could implicate a different local growth factor or cytokine. [less ▲]

Hepatitis B (HBV) reactivation induced by chemotherapy is problem encountered recently in the management of malignant diseases. Chemotherapy-induced HBV reactivation may ultimately lead to terminal acute liver failure. Liver transplantation (LT) currently remains the only definitive treatment option for such cases, but is generally denied to patients suffering from malignancy. Here, the authors describe 2 cases of cancer-free and HBV graft re-infection-free survival after LT performed for terminal liver failure arising from HBV reactivation induced by chemotherapy for advanced stage lymphoma. These 2 cases, and some other reports in the literature, may suggest that patients suffering from hematologic malignancies and terminal liver disease can be considered for LT if the prognosis of their hematologic malignancy is good.
