Different patterns of chromosomal imbalances in metastasising and non-metastasising primary breast carcinomas.

Abstract excerpt

In an attempt to identify chromosomal abnormalities that may be associated with a metastatic phenotype, we investigated the pattern of chromosomal gains and losses in 66 node-positive and 63 node-negative primary breast carcinomas. For both subgroups of tumours, losses were more common than gains and the losses were most often the result of structural aberrations. The exceptions were the long arm of chromosome 1,...
