title: [Antigen, containing tryptophan metabolite, 3-oxyanthranilic acid, in blood serum of patients with stomach neoplasms].
abstract: The results of studies of the antigen containing 3-oxyanthranilic acid (3-OAA-antigen), as one of determinantal groups, in blood serum of patients with tumor and pretumor lesions of the stomach indicated that the former is present in the majority of patients with cancer proved histologically and also in some patients with pretumor diseases of the stomach. 3-OAA-antigen is found to be absent in health donors blood serum. The importance of the data obtained for establishing an early diagnosis of gastric cancer is discussed.
