A phase I trial was conducted to evaluate the feasibility, safety, and efficacy of a dendritic cell-based vaccination in patients with metastatic renal cell carcinoma (RCC). Autologous mature dendritic cells derived from peripheral blood monocytes were pulsed with the HLA-A2-binding MUC1 peptides (M1.1 and M1.2). For the activation of CD4(+) T-helper(More)
BACKGROUND Bloodstream infections (BSIs) caused by enterobacteria remain a leading cause of mortality in patients with chemotherapy-induced neutropenia. The rate and type of colonization and infection with ESBL-producing Enterobacteriaceae (ESBL-E) and their mode of transmission in German cancer centres is largely unknown. METHODS We performed a(More)
The aim of this phase I/II nonrandomized trial was to assess feasibility, safety as well as immunological and clinical responses of a mRNA-based vaccination in patients with stage IV renal cell cancer using granulocyte-macrophage colony stimulating factor (GM-CSF) as adjuvant. Intradermal injections of in vitro transcribed naked mRNA, which was generated(More)
During the past few years, a huge amount of information about HLA-presented peptides has been compiled: several thousand naturally processed ligands of such cell surface receptors are already known. Nevertheless, our knowledge covers only a minute proportion of the total peptide repertoire. The overall amount of different peptides presented by one given HLA(More)
PURPOSE Identification of tumor-associated antigens and advances in tumor immunology resulted in the development of vaccination strategies to treat patients with malignant diseases. In a novel experimental approach that combined comparative mRNA expression analysis of defined cell types with the characterization of MHC ligands by mass spectrometry, we found(More)
AIM Granulocytic sarcomas (GS) are rare extramedullary manifestations of myeloid or lymphoblastic leukaemia. Laboratory examinations are of limited use for diagnosis of extramedullary disease. Radiological imaging based on morphology is challenging. To date, the possible role of FDG-PET/CT as a method for combined metabolic and morphologic imaging is(More)
PURPOSE A prerequisite for the development of vaccination strategies is the identification and characterization of relevant tumor-associated antigen. Using microarray and reverse transcription-PCR analysis, we found matrix metalloproteinase (MMP)-7 to be extensively up-regulated in renal cell carcinomas and expressed in a broad variety of malignant cells.(More)
Advances in tumor immunology and Identification of tumor-associated antigens (TAAs) provide a basis for the development of novel immunotherapies to treat malignant diseases. In order to identify novel TAAs, we performed comparative microarray analysis of (heterogeneous) tissues and found regulator of G protein-signaling 1 (RGS1) extensively up-regulated in(More)
BACKGROUND Lung volume reduction (LVR) improves breathing mechanics by reducing hyperinflation. Lobar selection usually focuses on choosing the most destroyed emphysematous lobes as seen on an inspiratory CT scan. However, it has never been shown to what extent these densitometric CT parameters predict the least deflation of an individual lobe during(More)
HISTORY AND ADMISSION FINDINGS We report on the case of a young women presenting with macrohaematuria, petechiae and strong headaches. INVESTIGATIONS Laboratory showed a thrombotic microangiopathy with helmet cells, increased LDH levels (>600 U/l), and thrombocytopenia (<40,000/μl). DIAGNOSIS, TREATMENT AND COURSE Due to strong haemolytic activity and(More)
