Integrative survival analysis of breast cancer with gene expression and DNA methylation data

Isabelle Bichindaritz, Guanghui Liu, Christopher L. Bartlett

Abstract: Integrative multi-feature fusion analysis on biomedical data has gained much attention recently. In breast cancer, existing studies have demonstrated that combining genomic mRNA data and DNA methylation data can better stratify cancer patients with distinct prognosis than using single signature. However, those existing methods are simply combining these gene features in series and have ignored the correlations between separate omics dimensions over time.
