OBJECTIVE Various preparative protocols have been proposed for the acquisition and cultivation of mesenchymal stem cells (MSC). Whereas surface antigen markers have failed to precisely define this population, microarray analysis might provide a better tool for characterization of MSC. METHODS In this study, we have analyzed global gene expression profiles(More)
To evaluate outcome and prognosis of patients with T-cell lymphoma we analyzed 343 patients treated within trials of the German High-Grade Non-Hodgkin Lymphoma Study Group (DSHNHL). Two hundred eighty-nine patients belonged to 1 of the 4 major T-cell lymphoma subtypes: anaplastic large cell lymphoma (ALCL), anaplastic large cell lymphoma kinase(More)
PURPOSE Although thalidomide (Thal) was introduced successfully in the treatment of multiple myeloma (MM), the optimal Thal dosage and schedule are still controversial. The aim of this study was to analyze whether the effect of Thal in MM is dose dependent and whether the outcome might be improved when the Thal dosage is adjusted to parameters reflecting(More)
BACKGROUND Cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) is used to treat patients with non-Hodgkin lymphoma. Interval decrease from 3 weeks of treatment (CHOP-21) to 2 weeks (CHOP-14), and addition of rituximab to CHOP-21 (R-CHOP-21) has been shown to improve outcome in elderly patients with diffuse large B-cell lymphoma (DLBCL).

Mesenchymal stromal cells (MSC) provide a supportive cellular microenvironment and are able to maintain the self-renewal capacity of hematopoietic progenitor cells (HPC). Isolation procedures for MSC vary extensively, and this may influence their biologic properties. In this study, we have compared human MSC isolated from bone marrow (BM) using two culture(More)
PURPOSE With whole-body magnetic resonance imaging (wb-MRI), almost the whole bone marrow compartment can be examined in patients with monoclonal plasma cell disease. Focal lesions (FLs) detected by spinal MRI have been of prognostic significance in symptomatic multiple myeloma (sMM). In this study, we investigated the prognostic significance of FLs in(More)
Epigenetic modifications of cytosine residues in the DNA play a critical role for cellular differentiation and potentially also for aging. In mesenchymal stromal cells (MSC) from human bone marrow we have previously demonstrated age-associated methylation changes at specific CpG-sites of developmental genes. In continuation of this work, we have now(More)
PURPOSE The optimal regimen to prevent chemotherapy-induced nausea and vomiting (CINV) for patients undergoing high-dose chemotherapy and autologous stem-cell transplantation (ASCT) is unclear. To evaluate the effect of aprepitant in addition to a standard regimen, we conducted this randomized, placebo-controlled phase III trial. PATIENTS AND METHODS(More)
BACKGROUND We used 2-deoxy-2-[(18)F]fluoro-D-glucose (FDG) positron emission tomography (PET) to evaluate the FDG uptake in patients with soft tissue sarcoma (STS). Treatment effect was assessed with regard to prediction of therapy outcome. PATIENTS AND METHODS The ongoing evaluation includes 27 patients with high-risk STS receiving chemotherapy(More)
Mesenchymal stem cells (MSC) comprise a promising tool for cellular therapy. These cells are usually culture expanded prior to their application. However, a precise molecular definition of MSC and the sequel of long-term in vitro culture are yet unknown. In this study, we have addressed the impact of replicative senescence on human MSC preparations. Within(More)
