Chromosome Abnormalities in Leukemia

The renewed interest in the study of chromosome abnormalities in hematologic malignancies, particularly in the leukemias, is the result of technical improvements which permit the precise identification of each human chromosome, and of parts of chromosomes as well. The information obtained raises a number of questions regarding the validity of older notions, such as the variability of the chromo...

[Chromosome abnormalities in neuroblastoma].

The case is briefly reported of a 7-month-old boy with a disseminated neuroblastoma, whose marrow showed neuroblastoma rosettes and on direct examination on two occasions revealed a high proportion of cells with 48 chromosomes forming an abnormal cell line.

Making chromosome abnormalities treatable conditions.

Individuals affected by the classic chromosome deletion syndromes which were first identified at the beginning of the genetic age, are now positioned to benefit from genomic advances. This issue highlights five of these conditions (4p-, 5p-, 11q-, 18p-, and 18q-). It focuses on the increased in understanding of the molecular underpinnings and envisions how these can be transformed into effectiv...

Numerical and structural chromosome abnormalities

| Genetic instability, which includes both numerical and structural chromosomal abnormalities, is a hallmark of cancer. Whereas the structural chromosome rearrangements have received substantial attention, the role of whole-chromosome aneuploidy in cancer is much less well-understood. Here we review recent progress in understanding the roles of whole-chromosome aneuploidy in cancer, including t...
