title: [Use of the carcinoembryonic antigen in the gastric juice for diagnosing pretumorous stomach diseases].
abstract: Radioimmunologic procedures were employed in comparing the levels of carcino-embryonic antigen in the gastric juice, blood plasma and saliva in cases of stomach cancer, gastritis, polyposis and gastric ulcer. No correlation between the antigen levels in different biological fluids was established. It was found, however, that the assay of carcino-embryonic antigen level in gastric juice may be instrumental in detecting precancerous lesions of the stomach.
