Abstract: The invention relates to methods for typing a sample of an individual suffering from a colorectal cancer, or suspected of suffering therefrom. A preferred sample is stool. The invention further relates to methods for determining a level of expression of at least two extracted protein expression molecules in stool, based on the quantified reaction products, and to methods of assigning treatment to an individual that was typed as suffering from colorectal cancer according to the invention.

Abstract: Protein-based methods and compositions for the diagnosis of colorectal adenocarcinoma are disclosed. A method for identifying cell-surface proteins, which are transmembrane proteins or proteins with a signal peptide and which are over-expressed in colorectal cancer (CRC) is disclosed. Biomarkers found with this method, diagnostic methods using them and contrast agents directed to them for use in magnetic resonance imaging (MRI) and/or magentic photon imaging (MPI) are disclosed. The methods and biomarkers allow for differentiating progressive (high-risk) CRC (adenocarcinomas) from non-progressive (low-risk) colorectal adenomas.
