Circulating blood group related carbohydrate antigens as tumour markers

Abstract

The various blood group related carbohydrate structures which are in clinical use as circulating tumour makers are reviewed. Their location on carbohydrate chains and their structural characteristics are shown, and their clinical performance in various malignant diseases is reviewed. The available data on their sensitivity, specificity and predictive value are shown; and carcinomas of the pancreas, ventricle, colon-rectum and ovary are identified as diseases in which these markers can be of good benefit for follow-up. Future research should be devoted to studies of the function of these structures, and to studies of their gene-transcription.
