Abstract
We evaluated the incidence of trisomy 11 in acute myeloblastic leukemia (AML) and its correlation with the most relevant clinical, biological, and immunophenotypic disease characteristics in a total of 399 consecutive AML patients. Trisomy 11 was found in 15 patients (3.8%), in 3 of them as the sole abnormality. Median age was 68 years (range 48-87); 87% of patients were older than 60 years. Seven patients displayed multilineage dysplasia. Cytogenetics showed an association with trisomy 8 in six patients, and in five cases with a del(5q); nine patients had complex karyotypes. In all cases, in situ hybridization studies revealed three copies of the MLL gene, but no rearrangements or tandem duplications of MLL. Immunophenotypic analysis of blast cells showed a constant immature immunophenotypic profile with CD34 or CD117 expression (or both) in all cases analyzed. The complete remission rate was 43%; median survival time was only 2 months.

Abstract
Tetrasomy, pentasomy, and hexasomy 8 (polysomy 8) are relatively rare compared to trisomy 8. Here we report on a series of 12 patients with acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), or myeloproliferative disorder (MPD) associated with polysomy 8 as detected by conventional cytogenetics and fluorescence in situ hybridization (FISH). In an attempt to better characterize the clinical and hematological profile of this cytogenetic entity, our data were combined with those of 105 published patients. Tetrasomy 8 was the most common presentation of polysomy 8. In 60.7% of patients, polysomy 8 occurred as part of complex changes (16.2% with 11q23 rearrangements). No cryptic MLL rearrangements were found in cases in which polysomy 8 was the only karyotypic change. Our study demonstrates the existence of a polysomy 8 syndrome, which represents a subtype of AML, MDS, and MPD characterized by a high incidence of secondary diseases, myelomonocytic or monocytic involvement in AML and poor overall survival (6 months). Age significantly reduced median survival, but associated cytogenetic abnormalities did not modify it. Cytogenetic results further demonstrate an in vitro preferential growth of the cells with a high level of aneuploidy suggesting a selective advantage for polysomy 8 cells.

Abstract
Trisomy 8/8q is a common cytogenetic event in myelocytic malignancies, ranging from myelodysplastic syndrome (MDS) to acute myelocytic leukemia (AML) to blastic transformation of chronic myelocytic leukemia. Isochromosome 8q results in the same gene dosage effect. Duplication of i(8q), resulting in pentasomy 8q, has been reported only in two cases of AML. A patient with fibrosing alveolitis on prolonged cyclophosphamide treatment developed therapy-related MDS. Karyotyping, FISH, and CGH analysis showed a duplicated i(8q) among other complex abnormalities. The clinical features of 11 cases of myelocytic leukemia with pentasomy and hexasomy 8/8q were summarized. Compared with trisomy and tetrasomy 8, significant features included reduced median survival (90 days), treatment refractoriness (even with transplantation), monocytic differentiation, trilineage dysplasia, and radiation or toxin exposure. Increasing copy numbers of chromosome 8/8q may therefore be a marker of advanced leukemic evolution, exposure to toxins, underlying myelodysplasia, and an overall poor prognosis.

Abstract
Isolated trisomy 11 is the third most common sole trisomy in de novo acute myeloid leukaemia (AML). However, only 49 cases have been published, and for only a fraction of these cases has full description of clinical and haematological features been provided. As a result, little is known about the clinical characteristics of de novo AML patients with solitary trisomy 11. We have identified 13 patients (0.9%) with isolated trisomy 11 among a total of 1496 consecutive adult patients successfully karyotyped as part of a prospective Cancer and Leukemia Group B (CALGB) cytogenetic study (CALGB 8461). Nine patients (69%) were over the age of 60 (range 29-73 years). Eight patients (62%) were diagnosed with AML of FAB M2 subtype, three patients (23%) had FAB M1 AML and one patient each had AML of FAB M0 and M7, respectively. Seven patients (54%) had high, >100 x 10(9)/l, platelet counts (median 102 x 10(9)/l; range 17-207 x 10(9)/l). All patients received CALGB induction therapy with standard doses of cytarabine and daunorubicin. Six patients (46%) achieved a complete remission (CR). The median CR duration was 17.5 months (range 8.7-49.8). Only one patient, who underwent bone marrow transplantation in first CR, continues in initial CR. The median survival was 14.3 months (range 0.5-50.7); only one patient survives. We conclude that de novo AML with isolated trisomy 11 is predominantly associated with older age, M2 and M1 FAB subtypes, high platelet count and few long-term disease-free survivals, although it is currently unknown whether isolated trisomy 11 constitutes an independent prognostic factor.

Abstract
Tetrasomy 8 is a rare form of acquired aneuploidy found exclusively in the myeloid leukemias. Hexasomy 8 is even rarer: only one case has been reported, thus far. We describe here the second case of hexasomy 8 as the sole abnormality in an elderly female patient with myelodysplastic syndrome (MDS).

Abstract
We report four cases of polysomy 8 (one tetrasomy and three pentasomies) observed in acute monocytic leukemia (FAB M4 and M5). Three of them showed a rearrangement of 11q23 identified by conventional cytogenetic analysis and/or chromosome painting. Our cases as well as a review of the literature, suggest that polysomy 8 is preferentially associated with monocytic differentiation (24/31). These polysomies have been observed in 21 de novo leukemias and in 10 secondary hematological disorders. A 11q23 rearrangement has been detected in 9 out of 32 patients, by conventional cytogenetic techniques in 7 and by FISH in 2. We suggest that these cases should be analysed by FISH and molecular studies in order to detect a rearrangement of MLL/11q23. Monocytic differentiation is often associated with a change of the MLL gene and the polysomy 8 might be a particular clonal evolution secondary to 11q23 abnormality.

Abstract
We describe a case of a 14.5-year-old boy with a clinically aggressive pelvic Ewing sarcoma. The tumor cells showed the presence of a typical t(11;22)(q24;q12) aberration and gains of chromosomes 8, 10, 14, and 21. To determine the size of the trisomy and tetrasomy 8 clones an interphase analysis by fluorescence in situ hybridization with a centromere-specific chromosome 8 probe was performed. Significant quantitative differences between metaphase and interphase data were obtained. It was shown that culturing of bone marrow cells leads to enrichment of tetrasomy 8 population that may be explained by the proliferative advantage of the tetrasomy 8 cells.
