8. Consensus Molecular Subtypes (CMS) for
colorectal cancers
Guinney et. al., Nat Med. 2015.
• CMS are mostly driven by gene-expression
• 19 % can not be assigned to a subtype

17. We are looking for collaborations and
partnerships
• Platform for omics data with our DL/ML methods
• Looking for:
• Clinical variables: response, survival, resistance, etc.
• Tumor models or primary tumors
• Small samples (n=15-20) can work, we do data augmentation
