Chromosomes have been studied in cultures of nucleated peripheral blood cells in 30 patients with myeloma. Both unstimulated cultures and cultures stimulated by phytohemagglutinin (PHA) were examined in all cases. Mitoses were observed in 13 unstimulated cultures of peripheral blood from 12 cases, providing evidence for the presence of circulating abnormal cells in these patients. In 19 stimula...

Diabetes insipidus and thrombocytosis were presenting symptoms in a case of adult ANLL-M1. Cytogenetic investigations revealed a typical 3q rearrangement, i.e. inv(3)(q21q26). A subclone with monosomy 7 was also found and documented by FISH analysis. Correlations between clinical/hematological features and cytogenetic/FISH results are discussed.

We report a remarkable association of recurrent (stereotyped) cytogenetic aberrations with two subsets of chronic lymphocytic leukemia (CLL) cases expressing IgG-switched, stereotyped B-cell receptors (BCRs). Comparison with cases with heterogeneous BCRs showed that these recurrent cytogenetic aberrations were subset-biased. These findings further support a role for antigen in CLL development.

BACKGROUND AND OBJECTIVE Successful cytogenetic studies in Hodgkin's disease (HD) are rare, and, except for hyperdiploidy, no chromosome changes typical for this disorder have been described. The purpose of this study was to collect cytogenetic information from a new series of lymphoid neoplasms diagnosed either as classical HD or as Hodgkin's-like anaplastic large cell lymphoma (HD-like ALCL),...

Cytogenetic analysis of mixed lymphocyte and epithelial thymoma in a nonmyasthenic female patient revealed deletion of part of the short arm of chromosome 6. To our knowledge, this cytogenetic abnormality in a benign thymoma has not been previously described in the literature, which is reviewed.

Cytogenetic investigation of endometrial polyps revealed the presence of a t(6;14)(p21;q24) as the sole abnormality in three cases. All tumors showed a histopathological pattern of predominant stromal hyperplasia with scarce representation of glandular elements, suggesting that a cytogenetic subgroup characterized by the t(6;14) translocation can be associated with endometrial polyps with a pre...

Background: A patient with multiple myeloma developed myelodysplastic syndrome (MDS). Chromosomal analysis performed after the development of MDS revealed monosomy of chromosome 9 in all the meta-phases. We wished to identify the extent of the clone with the chromosomal abnormality originating from MDS clone. Methods: A correlative interphase study by fluorescence in situ hybridization (FISH) w...

We describe a patient with acute myelomonocytic leukemia (AMML) in whom cytogenetic analysis revealed trisomy 4 associated with a ring chromosome. In addition, in a cytogenetically unrelated clone, trisomy 8 and 5q- abnormalities were detectable. The possibility of a subclinical myelodysplastic syndrome preceding the onset of AML is discussed on the basis of the morphological and cytogenetic fi...

The 2013 version of the European LeukemiaNet (ELN) recommendations for the management of chronic myeloid leukemia (CML) patients defines as optimal response the achievement of a partial cytogenetic response (PCyR) and/or BCR-ABL1 transcript ≤10% IS at 3 months, and of a complete cytogenetic response (CCyR) and/or BCR-ABL1 transcript ≤1% IS at 6 months.
