Prognostic stratification of Dukes B colon cancer by a neoglycoprotein.

Disease progression of tumors is accompanied by structural changes of the glycan chains of cellular glycoconjugates. Within the concept of the sugar code the presence of complementary receptors such as lectins translates changes in ligand presentation into biological effects, for example in growth regulation and adhesion. By introducing neoglycoproteins to histopathological colon cancer analysis the questions are addressed as to whether specific binding sites for main N- and O-glycan components are present and whether they harbor potential for prognostic predictions.
