Percentage of samples within each TC group with gene expression profiling evidence for 3 or more trisomies of chromosomes 3, 5, 7, 9, 11, 15, 19, or 21
Percentage of samples within each TC group with an expression PI greater then 0.2. There is a PI >0.2 in 67% of relapsed samples, and 10% of newly diagnosed MM (P < 10-13)
Percentage of samples within each TC group from patients with lytic lesions on MRI. In pairwise comparisons, each of groups 11q13, D1, and D1 + D2 is significantly different (P < .05) from each of groups D2, 4p16, and maf
