Figure 1From: An array CGH based genomic instability index (G2I) is predictive of clinical outcome in breast cancer and reveals a subset of tumors without lymph node involvement but with poor prognosis tumoral classification according to array CGH genomic profile. Unsupervised hierarchical clustering using genomic copy number variation enables the classification of the 135 breast carcinomas into six branches. MR, black: metastatic relapse; HR, black: positive for steroid hormonal receptors; Her2, black: Her2 score 3+; p53, black: TP53 mutation or protein overexpression; NPI (Nottingham prognostic index) red: NPI-1, blue: NPI-2, green: NPI-3, orange: NPI-4; G2I (genomic instability index) red: G2I-1, blue: G2I-2, green: G2I-3.Back to article page
