- The impact of cytogenetic characterization based on chromosome banding analyses and fluorescence in situ hybridization on clinical decision making has increased dramatically during recent years. Therefore, laboratory techniques have to be optimized to provide reliable results for optimal patient care. In addition, quick and correct results save time and money by preventing unnecessary additional diagnostics and suboptimal treatment approaches. It was our aim to present proposals for standardized protocols to improve the diagnosis, and hence the treatment outcome, of hematologic malignancies.

- The only way to cure leukemia is by cooperative research. To optimize research, the European Leukemia Net integrates 105 national leukemia trial groups and networks, 105 interdisciplinary partner groups and about 1,000 leukemia specialists from 175 institutions. They care for tens of thousands of leukemia patients in 33 countries across Europe. Their ultimate goal is to cure leukemia. Since its inception in 2002, the European Leukemia Net has steadily expanded and has unified leukemia research across Europe. The European Leukemia Net grew from two major roots: 1) the German Competence Network on Acute and Chronic Leukemias; and 2) the collaboration of European Investigators on Chronic Myeloid Leukemia. The European Leukemia Net has improved leukemia research and management across Europe. Its concept has led to funding by the European Commission as a network of excellence. Other sources (European Science Foundation; European Leukemia Net-Foundation) will take over when the support of the European Commission ends.

- Myelodysplastic syndromes and acute myeloid leukemia with an isodicentric X chromosome [idic(X)(q13)] occur in elderly women and frequently display ringed sideroblasts. Because of the rarity of idic(X)(q13), little is known about its formation, whether a fusion gene is generated, and patterns of additional aberrations. We here present a SNP array study of 14 idic(X)-positive myeloid malignancies, collected through an international collaborative effort. The breakpoints clustered in two regions of segmental duplications and were not in a gene, making dosage effects from the concurrent gain of Xpter-q13 and loss of Xq13-qter, rather than a fusion gene, the most likely pathogenetic outcome. Methylation analysis revealed involvement of the inactive X chromosomes in five cases and of the active in two. The ABCB7 gene, mutated in X-linked sideroblastic anemia and spinocerebellar ataxia, is in the deleted region, suggesting that loss of this gene underlies the frequent presence of ringed sideroblasts. Additional genetic abnormalities were present in 12/14 (86%), including partial uniparental disomies for 9p (1 case) and 4q (2 cases) associated with homozygous mutations of JAK2 and TET2, respectively. In total, TET2 mutations were seen in 4/11 (36%) analyzed cases, thus constituting a common secondary event in idic(X)-positive malignancies.
