Validation of 4 prognostic markers using CNAs inferred from independent data sets (GLSG2000 + BC Cancer). Kaplan-Meier curves for PFS are presented for (A) TP53 deletion, (B) CDKN2A deletion, (C) total aberration count among the 4 markers inferable from the m7-FLIPI study, and (D) total aberration count among the same markers in the current study. The 4 markers are deletions of TP53, CDKN2A, and CREBBP, and gain of CD79B.
