the expression of carcinoembryonic antigen ( cea ) and related antigens in 40 formalin-fixed paraffin embedded tissues of 4 histological types of lung carcinomas was examined immunohistochemically using five monoclonal antibodies ( moabs ) which distinguished different epitopes on cea , and the correlation with serum-cea ( s-cea ) level and tissue-cea ( t-cea ) was also investigated .
