Genomic imbalances detected in individual samples. Gains (red) and losses (green) of genomic material were detected in all samples investigated by array comparative genomic hybridisation (aCGH). Each row corresponds to a separate sample and each column represents an individual chromosome. The respective relapse was investigated in four cases, and samples from the same tumour showed very similar patterns of aberrations. However, although the pattern of aberrations was almost identical, a few aberrations escaped detection in one of the samples from the same tumour. This was primarily found for low copy number changes and can most probably be explained by normal cell contamination (See online version for colour figure.).
