TP53 and T-cell non-Hodgkin lymphoma: Chromosome gains were more frequent than chromosome losses and, although any of the 20 chromosomes could be affected, gains of chromosomes 14 and 15 were found in more than 50% of the metaphases analyzed in both T cell lymphomas (Figure 1B; Table S3), suggesting that one or multiple selection mechanisms shape aneuploidy in p53-deficient tumors.
