[Carcinoembryonic antigen. Evaluation in intestinal lavage fluids and in the tissue of colorectal tumors]

Abstract

Carcinoembryonic antigen in pre-operative or pre-endoscopic intestinal lavage rinsing fluids was assayed in 21 healthy subjects, 15 presenting polyps and 12 presenting colorectal cancer. Comparison of the results with those of histological and immunohistological studies showed that this assay did not allow detection of intestinal cancer or evaluation of its developmental stage.
