Abstract
The measurement of serum sialic acid in sera from individuals with leukemia, breast, gastrointestinal, lung and bladder cancers, brucellosis and manic depression is described. The serum sialic acid levels were also examined in mice bearing Landschutz ascites tumours. The presence of sialic acid-enriched glycopeptides in serum was shown. The results indicate that while sialic acid may be significantly elevated in sera of some tumour-bearing individuals, it is not solely tumour-derived. Its application as a tumour marker is limited and requires critical analysis.
