title: Tissue CEA as prognostic indicator in a series of 31 cases of gastric cancer.
abstract: The role of tissue CEA localization as a complementary factor in prognosis of patients affected by gastric cancer is analyzed. In a group of 31 gastric tumors, tissue CEA was always present in the apical portion of the tumor cell cytoplasm and in the glandular lumen, while in 23 cases it was found in the stroma, and in superficial and deep cell cytoplasm in 26 and 20 cases respectively. The serum marker levels were over 3 ng/ml in 19 patients. A relationship between CEA localization and tumor stage was observed. The more the tumors were advanced, the more the marker was found in the stroma and in the cytoplasm of superficial and deep cells. The same was found for CEA localization and serum CEA levels. The opposite trend was evidenced for the degree of tumor differentiation. In well differentiated tumors in a high percentage of cases the marker was present in the stroma and in the cytoplasm of superficial and deep cells as compared with undifferentiated tumors. No relationship between the histologic type and CEA localization was found.
