Study on CEA Content of Gastric Mucosa and It's Clinic Significant

Abstract We determinated CEA content from the gastric mucosa of 306 patients who had gastric disease by immunohistochemical analysis. The CEA positive rate were 77. 22% in non-atrophic gastritis, 86. 47% in atrophic gastritisand 94. 68% in gastric cancer. Which meaning of diagnosis wasn't valuable. But the rank colleration analysis was strongly significance. The CEA content was positively correlated with the lesion degress of atrophic gastritis or gastric cancer (R 0. 7).From these results we conclue that determination of CEA content from gastric mucosa was valuable to monitoring atrophic gastritis prognosis.
