THE RELATIONShIIP BETWEEN PROGNOSIS AND IMMUNO-HISTOCHEMISTRY OF CEA IN GASTRIC CAREINOMA:111 CASES

Gastric cancer specimens obtained fro m 111 patients who had undergone surgery were stained for carcinoembryonic antigen (CEA) by the avidinbiotin-perogidase complex (ABC) method. These findings suggest that CEA rectivity can be used as a diagnostic and prognostic marger for gastric carcinoma. The petients without lymph node metastasis 5-year survival rate was high especially in the CEA(-)group (81.82%), the survival rate of the CEA(+) group and the CEA(++) group were 53-97% and 10.95%. The patients with lymph node metastasis 5-year survival rate was low in the CEA(++) group. The survival rate of the CEA(++) group CEA(-) and CEA(++) group was 60%, 20.2% and 4.5%, respectively.
