title: [Ganglioside and carcinoembryonic antigens in the diagnosis of malignant tumors of the gastrointestinal tract].
abstract: Radioimmunologic procedures were used in a comparative assay of ganglioside and carcinoembryonic antigen levels in the blood plasma of patients with benign and malignant lesions at different sites. Measurements of ganglioside antigen level proved to be an efficient test for differentiating between benign and malignant tumors of the pancreas. However, it cannot be used as an aid to carcinoembryonic antigen test for detection of stomach and rectal cancers or their recurrences and metastases into the liver.
