Carbohydrate content of endoscopic gastric biopsies in carcinoma of the stomach.
Abstract
An investigation of the glycoproteins of gastric mucus from biopsies of patients with gastric cancer has shown a change in certain carbohydrate components. There is a significant increase (P less than 0-001) in mannose and a significant decrease in N-acetylgalactosamine in both secretors and non-secretors from cancer-free and cancer-bearing regions of the stomach as compared with normal stomachs. The possible reasons for this change and its relation to two possible glycoprotein fractions are discussed.
