Allogeneic transplantation in multiple myeloma: long-term follow-up and cytogenetic subgroup analysis.

This phase 3 trial compared tandem autologous stem cell transplantation (autoSCT) versus autoSCT followed by reduced-intensity conditioning allogeneic stem cell transplantation (auto/alloSCT) in patients with newly diagnosed multiple myeloma (MM) with deletion of (del) chromosome 13q (del13q). The availability/absence of a human leukocyte antigen-matched-related or matched-unrelated donor (MUD) determined the nature of the second SCT. The primary endpoint was progression-free survival (PFS) in the intention-to-treat population (n = 199).

A prospective, randomized evaluation of the feasibility of exergaming on patients undergoing hematopoietic stem cell transplantation.

The positive effects of physical and sports therapy for strain dependent physical practice and improved quality of life (QoL) are well known. Nevertheless, the available capacities and problem-oriented therapies in the setting of hematopoietic stem cell transplantation (HSCT) are limited. We conducted a prospective, randomized study among 42 HSCT recipients in order to investigate the influence of exergaming on Nintendo Wii or classical physiotherapy (PT) on physical fitness and psychological well-being.

Building a National Framework for Adolescent and Young Adult Hematology and Oncology and Transition from Pediatric to Adult Care: Report of the Inaugural Meeting of the "AjET" Working Group of the German Society for Pediatric Oncology and Hematology.

Adolescents and young adults (AYAs) with hemato-oncological problems constitute a heterogenous group with characteristic particularities, specific needs, and age-related clinical and unique psychosocial features. Strong collaboration between pediatric and adult hemato-oncology settings is essential to address their needs appropriately. This is not only true for patients who first become ill during adolescence or young adulthood, but equally so for people who contract hemato-oncological diseases congenitally or as younger children and who are now becoming old enough to leave the pediatric setting and have to transit into "adult" medical care.

Engraftment Efficiency after Intra-Bone Marrow versus Intravenous Transplantation of Bone Marrow Cells in a Canine Nonmyeloablative Dog Leukocyte Antigen-Identical Transplantation Model.

An intra-bone marrow (IBM) hematopoietic stem cell transplantation (HSCT) is assumed to optimize the homing process and therefore to improve engraftment as well as hematopoietic recovery compared with conventional i.v. HSCT.

Kinetics of Langerhans cell chimerism in the skin of dogs following 2 Gy TBI allogeneic hematopoietic stem cell transplantation.

Background: Langerhans cells (LC) are bone marrow-derived cells in the skin. The LC donor/recipient chimerism is assumed to influence the incidence and severity of graft-versus-host disease (GVHD) after hematopoietic stem cell transplantation (HSCT). In nonmyeloablative (NM) HSCT the appearance of acute GVHD is delayed when compared with myeloablative conditioning.

Immune responses to WT1 in patients with AML or MDS after chemotherapy and allogeneic stem cell transplantation.

Wilms' tumor gene 1 (WT1) is overexpressed in leukemia and WT1-derived CD8(+) T-cell epitopes for immunotherapies targeting WT1 have been defined. Here, we analyzed expression of WT1 in 226 peripheral blood and bone marrow samples from patients with acute myeloid leukemia or myelodysplastic syndrome (AML/MDS) before and after allogeneic stem cell transplantation (SCT). Transcripts were assessed by quantitative polymerase chain reaction, and WT1-specific CD8+ cytotoxic T cells (CTL) were monitored by tetramer staining and enzyme-linked immunospot (ELISPOT) assays.

Conditioning with treosulfan and fludarabine for patients with refractory or relapsed non-Hodgkin lymphoma.

The treatment of refractory or relapsed non-Hodgkin lymphoma (NHL) remains challenging. In this retrospective study, 88 patients with refractory or relapsed NHL received treosulfan and fludarabine as a reduced-intensity conditioning for allogeneic hematopoietic stem cell transplantation (allo-HSCT). Of the 88 intensely pre-treated patients, 73 experienced a relapse, with 18 of the 88 patients experiencing an early relapse (ER; <6 months from the last chemotherapy).

Modulation of lymphocyte subpopulations by extracorporeal photopheresis in patients with acute graft-versus-host disease or graft rejection.

Extracorporeal photopheresis (ECP) constitutes a promising treatment for patients with steroid-refractory acute graft-versus-host disease (aGvHD) after allogeneic stem cell transplantation and for patients with graft rejection after solid organ transplantation (SOT). There is an increasing body of evidence that modulation of lymphocyte subsets might play a crucial role in the mechanism of action in ECP. We therefore analyzed immunological effects concomitantly with clinical findings in patients under ECP therapy using multicolor flow cytometry.

Granulocyte-colony stimulating factor response is superior to neutropenia duration in predicting the risk of infection after high-dose chemotherapy for myeloma and lymphoma.

The patient granulocyte-colony stimulating factor (G-CSF) response is represented by the leukocyte peak in the blood induced by a single dose of G-CSF after chemotherapy, and is correlated with subsequent neutropenic infection risk. General patterns for a meaningful risk group stratification, have not yet been determined. Two independent data sets including a total of 306 cases with myeloma or lymphoma and autologous blood stem cell transplant were available.

Suppression of cytomegalovirus-specific CD8(+)T cells by everolimus.

Abstract Everolimus (RAD-001) has recently been used as an immunosuppressive drug to treat patients after hematopoietic stem cell transplant (HSCT), thereby reducing cyclosporine-related nephrotoxicity. We studied the immunomodulatory effect of everolimus on mitogen-stimulated and particularly cytomegalovirus (CMV)-specific cytotoxic T cells. Proliferation of CD4(+) and CD8(+) T cells stimulated with staphylococcal endotoxin B and phytohemagglutinin was strongly inhibited at very low doses.

Streptamer versus tetramer-based selection of functional cytomegalovirus-specific T cells.

Background/purpose: Cytomegalovirus (CMV) disease constitutes a serious complication after stem cell transplantation and has been treated by adoptive transfer of donor-derived CMV-specific CD8(+) T cells. CMV-specific CD8(+) T cells were selected by multimers, and the technologies may alter the function of these T cells. Therefore, here we evaluated the impact of multimer reagents on the function of CD8(+) T lymphocytes.

[Status of clinical trials in oncology--2013 and onwards].

Clinical trials connect basic science with patient care. They form the backbone of evidence-based medicine and clinical guidelines. The unprecedented implementation of new methods in oncology over the past 40 years has only been possible on the basis of multiple well-organized clinical study groups.

MicroRNA 181a influences the expression of HMGB1 and CD4 in acute Leukemias.

Dysregulation of microRNAs (miRs) has been linked to several types of cancer. In the present study, we investigated the expression of miR-181a in different leukemia cell lines and healthy hematopoietic cells, as well as its influence on cell proliferation, metabolic activity and potential targets. Expression of miR-181a differed between various leukemia cell lines and mature blood cells.

Validation of the grip test and human activity profile for evaluation of physical performance during the intermediate phase after allogeneic hematopoietic stem cell transplantation.

Objectives: The aims of the presented study were to validate tools evaluating physical functioning (PF) after allogeneic hematopoietic stem cell transplantation (alloHSCT) and to analyze the impact of the clinical course on PF.

Methods: Forty patients undergoing alloHSCT were enrolled in a prospective trial which included evaluation of muscle strength (grip test, CITEC dynamometer), endurance (2-min walk test), anxiety and depression (Hospital Anxiety and Depression Scale), fatigue (Modified Fatigue Impact Scale and Brief Fatigue Inventory), and physical activity (Human Activity Profile--HAP) before (t1) and 1 (t2) and 3 (t3) months after alloHSCT.

Results: At t2, all patients showed a 6 % (p = 0.

Chronic graft versus host disease but not the intensity of conditioning has impact on survival after allogeneic hematopoietic stem cell transplantation for advanced hematological diseases.

Background: Allogeneic hematopoietic stem cell transplantation (alloHSCT) is often performed in cases of advanced hematological diseases, but because of the associated mortality and a high risk of relapse it is life prolonging only in some patients.

Patients And Methods: A retrospective multi-center analysis of 401 patients was conducted to analyze the variables associated with outcome after alloHSCT in advanced hematological diseases. The Cox proportional hazards model was used to assess the independence of overall survival (OS) and disease-free survival (DFS) from prognostic factors in a multivariate model.

Outcome of relapsed adult lymphoblastic leukemia depends on response to salvage chemotherapy, prognostic factors, and performance of stem cell transplantation.

Despite improvements in first-line therapies, published results on the treatment of relapsed adult acute lymphoblastic leukemia (ALL) show that prognosis is still poor. The aim of the present retrospective analysis of the German Multicenter Study Group for Adult ALL was to identify prognostic factors and options for improvement. A total of 547 patients with a median age of 33 years (range, 15-55) experiencing their first relapse (406 vs 141 shorter or longer than 18 months from diagnosis) were evaluated.

Adult patients with acute lymphoblastic leukemia and molecular failure display a poor prognosis and are candidates for stem cell transplantation and targeted therapies.

Quantification of minimal residual disease (MRD) by real-time PCR directed to TCR and Ig gene rearrangements allows a refined evaluation of response in acute lymphoblastic leukemia (ALL). The German Multicenter Study Group for Adult ALL prospectively evaluated molecular response after induction/consolidation chemotherapy according to standardized methods and terminology in patients with Philadelphia chromosome-negative ALL. The cytologic complete response (CR) rate was 89% after induction phases 1 and 2.
