Serum sialic acid, fucose, sialic acid/fucose ratio as tumor markers in oral cancer.

To our knowledge, no study has been undertaken before by any researcher as to the direction of content of the components of serum glycoproteins simultaneously as well as their ratios in oral cancer patients. The aim of the present paper is to establish the direct relationship between fucose and sialic acid levels in the sera of such patients. The biochemical levels were studied among 37 oral cancer patients and were compared with 15 controls.
