title: Assessment of genomic imbalances in malignant fibrous histiocytomas by comparative genomic hybridization.
abstract: In order to investigate genomic imbalances, comparative genomic hybridization was applied to 20 malignant fibrous histiocytomas. Deletions were rare and found mainly in chromosomes 2q33-35, 4q32-qter, 8p, 9p21-pter, 12p and 19p, whereas, over-representations frequently affected chromosomes 3, 4q31, 5p, 6, 7, 14q22-ter, 18p, as well as, five distinct amplifications within the regions 12q12-15 and 15q24-qter. The total number of genetic imbalances per tumor was slightly increased in primary tumors when compared to relapses. No relationship was found between the patterns of gain and loss when compared to the histological subtype, tumor grading, the clinical outcome and the p53 mutation status.
