Distinct chromosomal imbalances in pleomorphic and in high-grade dedifferentiated liposarcomas.


Using comparative genomic hybridization, DNA copy number changes were studied in 14 pleomorphic liposarcomas and compared to those detected in high-grade areas of 9 dedifferentiated liposarcomas. A total of 251 gains and 84 losses were detected. The most frequent gains involved subregions of chromosomal arms 12q and 20q (70% each), 5p (57%), 6q and 9q (52… (More)
