Recurrent genomic abnormalities in (a) 19 relapsed and (b) 32 non-relapsed lymph node- negative (pN0) invasive breast cancer cases identified based on array CGH. Frequencies of genome copy number gains and losses are plotted as a function of genome location, with chromosome 1p to the left and chromosomes 22, X and Y to the right. Vertical lines indicate frequency of gain or loss. Gene copy-number gains and losses are indicated by red and green, respectively. Green asterisks are the regions that showed frequent gains in over 50% of the cases. Red asterisks are the regions that showed frequent losses in over 50% of these tumors. The chromosome loci that frequently showed gains or losses were common between the relapsed group and the non-relapsed group
