Hepatocellular cancer is a serious human disease with an unfortunately low survival rate. It further poses a significant epidemic threat to our society through its viral vectors associated with cirrhosis conditions preceding the cancer. A search for biomarkers of these diseases enlists analytical glycobiology, in general, and quantitative biomolecular mass spectrometry (MS), in particular, as valuable approaches to cancer research. The recent advances in quantitative glycan permethylation prior to MALDI-MS oligosaccharide profiling has enabled us to compare the glycan quantitative proportions in the small serum samples of cancer and cirrhotic patients against control individuals. We were further able to fractionate the major serum proteins from the minor components and compare statistically their differential glycosylation, elucidating some causes of quantitatively unusual glycosylation events. Numerous glycan structures were tentatively identified and connected with the origin proteins, with a particular emphasis on sialylated and fucosylated glycans.
