Figure 2: Genomic instability and patient age. The DNA index was plotted for patients aged<60 years in four increasing SSI intervals: ≤ 5 relative units (A), ≤ 8.8 relative units (B), ≤ 15 relative units (C), and ≤ 30 relative units (D). D- and T-type tumors dominated the two first SSI intervals, after which the triploid DI interval 1.2–1.8 increased, in particular the DI interval 1.4–1.8. Some few tumors with DNA-Index>3.0 were ecluded.
