Distribution of chromosome gains and losses as well as chromosomal breakpoints in the CKs of the present series within 3 aberrations (low-CK), 4 aberrations (intermediate-CK), and ≥5 aberrations (high-CK). (A) 3 aberrations (low-CK); (B) 4 aberrations (intermediate-CK); (C) ≥5 aberrations (high-CK). Gains, right green bars; losses, left red bars; translocation breakpoints, right blue bars adjacent to chromosomes. Ideograms were prepared with the CYDAS software package, freely available at www.cydas.org.
