title: [Carbohydrate antigen 19-9 (CA 19-9) and carcinoembryonic antigen in gastrointestinal neoplasms. Comparison of markers].
abstract: CA 19-9, a new antigenic tumor marker for gastrointestinal tumors, has been assayed with Carcinoembriogenic antigen, in 90 healthy patients and 47 patients with gastric cancer (20) and colorectal cancer (27). A good specificity has been found for this antigen (97.7%). Its sensibility seems to be slightly superior to that of CEA. However the sensibility for tumors at Mo stage (38%) is indeed scarcely, on the contrary it clearly elevated for tumors at advanced stage (M1)(76%).
