To evaluate the prognostic value of minimal residual disease (MRD) in patients with acute myeloid leukemia (AML) NPM1 mutation (NPM1(mut)).RNA-based real-time quantitative polymerase chain reaction (RQ-PCR) specific for detection six different NPM1(mut) types was applied to 1,682 samples (bone marrow, n = 1,272; blood, 410) serially obtained from 245 intensively treated younger adult who were 16 60 years old.NPM1(mut) transcript levels as a continuous variable significantly associated...

R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) is standard care for aggressive B-cell lymphoma. A prospective trial was conducted to investigate the role of additive radiotherapy (RT) bulky extralymphatic disease.The best arm RICOVER-60 (6×R-CHOP-14+2R [R-CHOP administered once every 2 weeks two additional applications rituximab] involved-field RT [36 Gy] sites initial [≥ 7.5 cm] disease involvement) compared with a cohort receiving same immunochemotherapy...

Based on histopathological examination of 264 exocrine pancreatic tumours (167 autopsy and 97 surgical) from the files Institute Pathology, University Hamburg, over a 15‐yr period (1966–1980), histogenetic classification is proposed. In addition to more common neoplasms this also includes rarer recently defined entities. Of tumours, 250 were duct origin, 10 acinar four uncertain histogenesis. Ductal adenocarcinoma, subdivided into well‐differentiated poorly‐differentiated type, was most...

Analogue peptides with enhanced binding affinity to major histocompatibility class (MHC) I molecules are currently being used in cancer patients elicit stronger T cell responses. However, it remains unclear as how alterations of anchor residues may affect receptor (TCR) recognition. We correlate functional, thermodynamic, and structural parameters TCR–peptide–MHC demonstrate the effect residue modifications human leukocyte antigens (HLA)–A2 tumor epitope NY–ESO-1157–165–SLLMWITQC on TCR The...

Purpose The tet oncogene family member 2 (TET2) gene was recently identified to be mutated in myeloid disorders including acute leukemia (AML). To date, there is increasing evidence for a functional role of TET2 mutations (TET2 mut ) AML. Thus, we explored the frequency, gene-expression pattern, and clinical impact large cohort patients with AML context other AML-associated aberrations. Patients Methods Samples from 783 younger adult were analyzed presence (coding exons 3 11), results...

Abstract. Accurate long-term monitoring of total ozone is one the most important requirements for identifying possible natural or anthropogenic changes in composition stratosphere. For this purpose, NDACC (Network Detection Atmospheric Composition Change) UV-visible Working Group has made recommendations improving and homogenizing retrieval columns from twilight zenith-sky visible spectrometers. These instruments, deployed all over world about 35 stations, allow measuring twice daily with...
